Title: Suction system device for direct-injection type diesel engine
Inventor: HASEGAWA SHIYUNPEI
IPC: F02B31/00
Filed: 1984-06-29
Abstract: PURPOSE:To form an optimum swirl over the whole operation range of an engine as well as to improve charging efficiency and combustibility either, by making a sense of a straight port direct little to a cylinder center, in case of an engine having a helical port to be normally opened and the straight port to be opened in time of high load. CONSTITUTION:Two suction ports 10 and 11 and one exhaust port 13 are all installed in one cylinder, and the suction port 10 is formed in spiral from and set down to a swirl port, while the suction port 11 is set down to a straight port. And, the swirl port 10 sucks air at the whole operation range from low load to high of an engine by the straight port 11 preforms suction air only in time of high load. Therefore, in time of low load, there is formed a strong swirl, while in the time of high load, a suction passage 9 of the straight port 11 is made to tilt toward the center of a cylinder 7 so that it works so as to cancel the strong swirl, thus improvements in stability in combustion and charging efficiency is promoted.

Title: Friction wheel power transmission mechanism
Inventor: HIRAOKA TAKAFUMI
IPC: F16H13/08
Filed: 1988-06-03
Abstract: PURPOSE:To carry out always stable lubrication in all circumstances in a friction-wheel power transmission mechanism consisting of a driving friction wheel and a driven friction wheel by providing a means of feeding the shifted film of a sold lubricant to the contact power transmission faces of the friction wheels. CONSTITUTION:A driven side friction wheel 2 as a driven wheel is brought into contact with a solid lubricating material block 3 on the outer periphery thereof immediately before the contact point A with a driving side friction wheel 1 as a driving wheel. A pressure contact force acts on a contact face B by means of a leaf spring 5 for joining a fulcrum 4 and the block 3. In such a structure, since the lubricant deposited on the surface of the driven side friction wheel 2 is sufficiently compressed and solidified by the pressing force acting on the contact point A, the films of the lubricant are formed on the surfaces of the friction wheels 1, 2. Thereby, always stable lubrication can be carried out in all circumstances.

Title: Vapor deposition pre-processing method
Inventor: KOBAYASHI TOSHIHIRO
IPC: H01L21/302
Filed: 1977-11-14
Abstract: PURPOSE: To form the evaporation film which features high adhesive force and causes no step break of the wiring through evaporation after the residue is removed through the sputtering process via the inactive gas of the incineration with O 2 .  
     CONSTITUTION: The complete removal of the resist film is difficult by the photo resist process before evaporation, so the organic matters and the impurities remain on the surface of the PSG film or the like. As a result, the step coverage is  deteriorated to produce the step break for the wiring evpaporation film of the  device. In this connection, the ozone sulphuric acid treatment is given to the opening surface of the electrode window before evaporation to remove the residue and  then to have the incinaration process. Otherwise, the residue is removed only  through the incineration process with no ozone sulphuric acid treatment, and then  Al is evaporated. Thus, the step break is reduced greatly. The sputtering process in  place of the incineration process can secure the same effect.
