The K. K. Toyota Chuo Kenkyusho patent solves the following problem:

The present invention relates to the development of recurring type swirl injection nozzle atomizing fuel using a tangential passage and a swirl chamber to give a nearly conical fuel spray by a hole nozzle, and especially into a recurring type swirl injection nozzle that is capable of controlling fuel spray angle, spray penetration (the reach of the spray) and atomization characteristics equivalent to lifting the needle valve, and thus the most suitable for use as a swirl injection nozzle designed to improve the performance of a direct-injection internal combustion engine with a single-hole, bowl-type especially in terms of reduced concentration.

Our analysis of this patent is as follows:

K. K. Toyota Chuo Kenkyusho’s patent US 4653694 A deals with Intermittent type swirl injection nozzle.
In a recurring type swirl injection nozzle including a nozzle body having a through hole and a spray hole, a needle valve is inserted into the through hole, and a partition member in a cylindrical form fittedly and fixedly inserted into the through hole, a gap between the needle valve, and the partition member increases according to lift the needle valve. For this purpose, a tapered portion and a top end face given to members of the partition in a way that they are in contact with a tapered portion and a measure of which the needle valve when the needle valve is in a position to close the spray hole. The resulting injection nozzle has a variable injection rate and spray angle.

The Data Medi-Card, Inc. patent solves the following problem:

This creation relates generally to a medical data card containing a summary of the medical history will be involved in his current medical condition, and especially an internal illuminated card in this manner that the front and rear transparencies component in a relatively large data capacity, the data taken as read and read directly without the need for optical lens.

Our analysis of this patent is as follows:

Data Medi-Card, Inc.’s patent US 4648189 A deals with Laminated medical data card.
An internal illuminated medical data card in a credit card format containing a summary of the medical history will be involved in his current medical condition. The card, which is laminated construction, includes a plastic core panel with light-passing property, a face of the panel that formed on it a metallized layer functioning as a double-face mirrors. Mounted on the surface layer and the other face of the panel, respectively, the front and rear film transparencies containing medical data in a direct read scale, the combined data elements needed summary. The long side and one end of the panel in a concave formation to define reflective convex end where the light to enter the remaining flat end panel and transmitted through the convex end and by the inner surface of the glass providing many internal reflection, causing the light to shine before transparency to improve its readability. And that light outward face in the mirror serves to increase the readability behind transparency.

The Manfred Ruedle, , Kurt Stoll patent solves the following problem:

The servo valve is used in a number of different forms. Deputy for the valve was found in compressed air and hydraulic circuits for vehicles, especially trucks. For the purposes of the servo valve must be made in general small production runs of different design details, as for example for working pressures of 10 to 16 bar. A lack of known servo valve so that it is difficult to make small production runs of customized valve at low prices. A further point is that, if for some reason or the other holes for fixing the valve in place and screw or the like for this purpose placed closer to each other, with additional deficit of the valve should be made smaller in size, it cut the rate of flow therethrough, that is to say the size of the ducts for the controlled fluid.

Our analysis of this patent is as follows:

Manfred Ruedle, , Kurt Stoll’s patent US 4646785 A deals with Spool valve.
A valve that includes a house, two axially spaced liners and a spool inner liners made screws running through the housing. To make it possible for the screws to be placed close together but not to make liners any smaller in diameter, the screw hole is cut through the liner portion of the housing. The screw holes are sealed from the outside by the washers provided under the screw heads and a gasket provided between the outer housing (over the head) and a support to the screws extend.

The Allied Corporation patent solves the following problem:

Our analysis of this patent is as follows:

Allied Corporation’s patent US 4646889 A deals with Compressor drive with oil distribution sleeve.
A compressor drive controls the driving connection between a vehicle engine and an air compressor. drive includes a clutch disc pack lubricated with lubricating fluid expressed through a passage of the spindle where the disc pack mounted. An arm mounted on the passage provides a flow-restricting orifice that controls communication into an annular chamber defined between the arms and the passage. Axial-spaced apertures allow fluid communication from the annular chamber of each pair of plates in the disc pack.
