Title: Air bag device
Inventor: USUI YASUSHI
IPC: B60R21/26
Filed: 1994-06-28
Abstract: PURPOSE:To improve instantaneous gas generation ability and quicken inflation speed so as to improve safety by arranging other end part of an unsealing metal fitting having U-shaped notched part approaching to the piston projection side of a trigger device. CONSTITUTION:When impact caused by collision with a vehicle is sensed, a trigger device is electrically triggered, thereby a piston in a cylinder is projected to the inside of a main. body cover 7 of an air bag, and one end of an unsealing metal fitting 12 opposing to a state approximately approaching to the piston is pressed. Then, respective thin notched parts formed at an aperture edge part of a cylinder to which U-shaped notched parts 13, 13 formed at the other end side of the unsealing metal fitting 12 are engaged are raised in the aperture direction of the cylinder by the principle of a lever so as to entirely remove the aperture edge part having a sealed plate at the tip and the storage gas in the inside is instantaneously released in the main body cover 7. Jetted gas is jetted to the air bag through through holes of the main body cover 7 so as to instantaneously inflate the folded air bag.

Title: Laser diode lighting system
Inventor: HASHIMOTO NOBUYUKI
IPC: H04N1/113
Filed: 1986-08-29
Abstract: PURPOSE:To make the amount of exposure per unit area constant by a method in which the light output of laser diode is modulated in such a way as to equalize exposure amount on a photo-sensitive material according to scanning speeds of a laser printer on the photo-sensitive material. CONSTITUTION:A reference voltage signal VR is applied to the inversional input terminal 13 of an operating amplifier 17. When the light output of a laser diode 7 increases for any cause, the monitor current of a photo diode 9 increases, voltage to be applied to a positive input terminal 15 and output potential of the amplifier 17 raise. The base potential of PNP-type transistor 5 also raises, and collector current reduces and thereby the light output of the diode 7 reduces. When the light output of the diode 7 decreases, the light output increases on the contrary to the foregoing. By using voltage proportional to the manitude of scanning speed of the laser beam of the diode 7 on a photo sensitive material as a reference voltage signal VR, the exposure amount per unit area of lasers can be made constant.

Title: Fuel injection device
Inventor: SUGA YOSHIMICHI
IPC: F02M67/02
Filed: 1991-07-16
Abstract: PURPOSE:To improve driving and prompt acceleration functions and fuel profitability of an engine in a high opening region by opening a switching valve of a second air route at middle to high opening regions of a throttle valve, and whereby forcibly supplying the compressed air in a surge tank into an injection valve injection route. CONSTITUTION:The negative pressure in an intake route 2A lower than a throttle valve 4 becomes smaller than the negative pressure in a low opening region of the throttle valve 4 when the throttle valve 4 is opened to middle to high regions from the low opening region of the throttle valve 4, and is thus driven. Since an ON signal is output to a switching valve 14 by a pressure sensor, a second air route 10 is opened by the switching valve 14, and the compressed air of no less than a fixed pressure which is accumulated in a surge tank 12 is injected from the second air route 10 to a first air route 8. The compressed air is mixed well with a fuel running through an injection valve injection route 7, and the mixed air is injected from an annular gap S into the intake route 2A. Since compressed air is forcibly supplied from the route 10 into the injection route 7 even when the amount of air or air current speed are reduced, a good mixed condition is provided.

Title: Protective layer for optical recording medium and its production
Inventor: SUGIYAMA YASUYUKI
IPC: G11B7/26
Filed: 1989-08-04
Abstract: PURPOSE:To prevent deterioration of disk performances due to repeated recording and erasing by forming dielectric protective layers having specified composition on both sides of a thin film recording layer by ECR plasma CVD method. CONSTITUTION:N2 plasma is produced in a plasma generating chamber 2 and blown from an outlet, into which SiH4 gas, for example, is introduced to be decomposed at high efficiency. Thus, a SiN film is formed by a vapor phase reaction and reaction on the substrate surface. SiN films, for example, are formed on both sides of the thin film recording layer by ECR plasma CVD method. As for the protective layers, Si-C, Si-O, and C-H can be used as well as Si-N. By this method, residual stress in the film can be arbitrarily controlled. By forming protective films having low residual stress, deterioration of disk performances due to repeated recording and erasing can be prevented. By this method, films can be deposited fast, which largely reduces the time of producing protective films.

Title: Freezer
Inventor: SHIMIZU YASUJI
IPC: F25B1/00
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent operation of a freezer from being interrupted under high fresh air temperature by providing means for changing over the flow of a liquid refrigerant to a gas/liquid heat exchanger and a bypass circuit on an inlet side of the liquid refrigerant of the gas/liquid heat exchanger, and controlling the changeover means such that discharge gas temperature from a compressor falls within a predetermined range. SOLUTION: Once discharge gas temperature from a compressor 3 exceeds an allowed value, a controller 17 that has received an output from a discharge gas temperature sensor 13 changes over an outlet of a three-way valve 14 from a gas/liquid heat exchanger 8 side to a bypass pipe 15 side. Thereupon, a fluid refrigerant from a condenser 4 bypasses the gas/liquid heat exchanger 8 and is fed to an expansion valve 9 after passage through the bypass pipe 15 where it undergoes heat insulation expansion. In the cource of its flowing through art evaporator 10 it heat exchanges and is evaporated with circulation air in a refrigerator into a gas refrigerant which in turn enters the gas/liquid heat exchanger 8.  Since the liquid refrigerant is unlikely to flow through the gas/liquid heat exchanger 8, the gas refrigerant is prevented from heat exchanging with the liquid refrigerant, and hence it is returned to the compressor 3 without increasing the degree of overheating.

When the answer is NO, a value obtained by subtracting the value STEP from the preceding output signal is sent to the 2nd output means S10 as a current output signal.  Each of the signals sent from the output means 4, 8, 10 is converted into an analog signal by a D/A converter and the analog signal is supplied to a speaker.
