Title: Canister purge controlling method and device for internal combustion engine
Inventor: NEMOTO MAMORU
IPC: F02D41/00
Filed: 1993-09-20
Abstract: PURPOSE:To suppress unnecessary fluctuation of an air-fuel ratio which is generated when a purging rate is abruptly varied in the case that recovered fuel in a fuel evaporation recovery device for an automobile is purged to an engine. CONSTITUTION:A purging rate is controlled by a throttle valve 6 in proportion to an air amount intaken from an inlet 3 of an air cleaner 2 to an internal combustion engine 1. During normal operation, a purging air-fuel ratio is calculated by means of a control unit 30 through a purging ratio and a feedback controlling rate of an air-fuel ratio. During transient operation of the internal combustion engine, a target air-fuel ratio feedback controlling rate is calculated through the purging ratio and the purging air-fuel ratio. When difference between the air-fuel ratio feedback controlling rate and the target air-fuel ratio feedback controlling rate is a specified value or more, the air-fuel ratio feedback controlling rate is corrected to be the target air-fuel ratio feedback controlling rate. It is thus possible to suppress unnecessary fluctuation of the air-fuel ratio to be supplied to a cylinder which is generated when the purging ratio is abruptly varied.

Title: Sunroof device of vehicle
Inventor: TSURUO AKIRA
IPC: B60J7/057
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce the cost with a simple structure and prevent the reduction in power transmission efficiency or the generation of noise by buckling by providing a buckling preventing shoe having a sectional form more adjacent to the inner wall of a guide rail than the circumferential surface of a rod in a prescribed position of the rod. SOLUTION: Guide members 41, 44 are also slid within a guide rail by pushing and pulling a rod 30. Even if a pressing directional load is added to the rod 30 by the frictional resistance of the guide members 41, 44 at that time, the rod 30 is strong and relatively difficult to buckle. When a considerably large pressing directional load is added to the rod 30 to buckle it, a shoe 31 situated in the intermediate part 30c of the rod 30 is pressed to the guide groove inner wall of the guide rail while sliding thereon. The buckling of the rod 30 is surely prevented by such a simple structure, and the reduction in power transmitting efficiency or generation of noise by buckling can be surely prevented without increasing the cost.

Filed: 1988-09-16
Abstract: PURPOSE: To set hair without damaging the hair, by setting a steam-generating- heater energization control position between the power source shut-off position of a switch and a motor energization control position. CONSTITUTION: For styling hair, steam is emitted out of the small holes 13 of a brush body 11 by plugging a power source code 6 into an electric outlet and operating a switch 19, thereby energizing a steam-generating heater 9. Thereafter, steam is continuously generated. This way, from the start to the end of making a curl in hair, proper moisture is given to the brush body 11 so as not to damage hair.

Title: Semiconductor photo detector
Inventor: KAGAWA SHIYUUZOU
IPC: H01L31/107
Filed: 1982-12-24
Abstract: PURPOSE:To obtain a device wherein a protection ring is unnecessitated and the surface is flat by providing a recess in a compound semiconductor substrate, and forming a compound semiconductor photo detector in the recess. CONSTITUTION:An SiO2 film is formed on the p<+> type InP substrate 11, and the recess of a diameter of approx. 300mum is provided by boring a window. Next, an n type InP multiplying layer 12, an n type InGaAs absorption layer 13, and an n<+> type InP connection layer 14 are successively laminated by an arbitrary method. The SiO2 film is flatted by polishing, and the surface is flatted by removing the other unnecessary part. Thereafter, the protection ring, a photo detecting window, and an electrode are formed as normal, thus completing the photo detector. This constitution causes an electric field to become rough at the part of the large curvature at a P-N junction. Therefore, the element does not yield even without the protection ring. Besides, since the surface is flat, there is no inconvenience to form the protection ring or the electrode.

Title: Digital-analog converting circuit
Inventor: HINO YOUJI
IPC: H03M1/00
Filed: 1982-12-29
Abstract: PURPOSE:To improve the linearity of an analog output to an input digital signal by connecting a D/A converter to a power supply or the earth via one of the 1st and 2nd resistances having different resistance values. CONSTITUTION:A P-MOS transistor TR1 of a switch means I0 consisting of an inverter of C-MOS structure is turned on by a digital signal A0. Then an analog signal is delivered to the VOUT by the earth through a resistor 2R'' when a TR2 of N-MOS is turned on by the Vref through the 1st resistor 2R'. The compensation is previously given to the change of resistance value of an integrated resisttor which is due to the back voltage of the bias applied to a substrate on the basis of the prescribed resistance value shown by resistors 2R' and 2R''. Thus it is possible to eliminate the effect of the substrate bias and to improve the linearity of an analog signal to a digital signal.
