Title: Air-fuel ratio control device for engine
Inventor: YOKOTA KAZUYA
IPC: F02D41/14
Filed: 1986-10-30
Abstract: PURPOSE:To judge the malfunction of an oxygen sensor irrespective of any variation in a supply of vaporing fuel, by installing a controlling device setting a purge valve down to non operation at a time when detecting output of an air-fuel ratio sensor is continued as long as the specified time and fixed to the overrich side or the lean side and, what is more it fails to reverse. CONSTITUTION:An electronic controller 9 performs air-fuel ratio feedback control by each detecting signal out of an air flow meter 2, an oxygen sensor 4 or the like. At this time, when exceeding an idle range, boost pressure comes to more than the specified value, whereby a purge valve 21 is opened by the negative pressure, and vaporing fuel in a canister 16 is fed to a suction passage via a three-way solenoid valve 30. Now, if detecting output of the oxygen sensor 4 is fixed to the overrich side or the lean side as long as the specified time, a signal is outputted to the three-way solenoid valve 30 from the ECU9, setting the purge valve down to nonoperation. Therefore, any malfunction of the oxygen sensor is kudgeable irrespective of variations in a feeding state of the vaporing fuel. Accordingly, such a possibility that air-fuel ratio feedback control is stopped by mistake, though the oxygen sensor is normal, is avoidable.

Title: Perfect adhesion type image sensor
Inventor: KASUYA YUKIO
IPC: H01L31/12
Filed: 1988-10-17
Abstract: PURPOSE:To miniaturize and lighten the whole remarkably, and to form a light-emitting device and a photodetector accurately at the positions of precise arrangement by shaping the photodetector onto a substrate and forming an integral structure in which the light-emitting device is shaped into the hole of the photodetector. CONSTITUTION:An image sensor is composed of at least a substrate 30 for loading an element, a photodetector 32 formed onto the substrate, a hole 34 shaped in a specified region in the photodetector, a light-emitting device 35 formed into the hole and a light-transmitting protective film 38 applied onto the photodetector and the light-emitting device. Since the photodetector 32 and the light-emitting device 35 are shaped onto the same substrate 30, the photodetector 32 and the light-emitting device 35 can be formed accurately at the positions of precise arrangement on a manufacturing process. Accordingly, the complicate operation of positioning at the time of the assembly work of a light source and the photodetector as seen in conventional devices can be omitted, thus simplifying the manufacturing process while enhancing reliability by the improvement of the accuracy of the coincidence of an optical axis.
Patent JP-H0574155-A (JP)
Title: Semiconductor memory device
Inventor: WADA ATSUSHI
IPC: G11C11/408
Filed: 1991-09-11
Abstract: PURPOSE:To check useless consumption of current flowing through an address recorder selecting no word line by arranging first and second transistors connected in series to operate complementarily and a plurality of third transistors connected in series. CONSTITUTION:When an array selection signal AS of a 'L' level is inputted, a transistor TRPT1 is turned ON and a TRNT2 is turned OFF while a node N1 is precharged to turn ON the TRPT2. With the TRPT2 ON, a PRNT5 is turned OFF. On the other hand, with a TRNT6 ON, a word line WL is held at the 'L' level even if a word line source generation circuit WLS is at a 'H' level and WL is not selected. Thus, when the WL is not selected, a circuit for connecting the node N1 and the TRNT1 is cut with a TRNT7. Thus, no consumption current flows through the TRNT1, NT2 and NT3 from the node N1.

Filed: 1989-10-05
Abstract: PURPOSE:To make the effective lighting time of a light source means which generates an exposing beam longer and to improve working rate by temporarily turning off the light source means for a specified time until the exposing beam reaches a photosensitive material. CONSTITUTION:A light source control means 5 is provided, which turns off the light source means 1 according to a signal showing the detection of the exposing beam by an exposing beam detection means 4 and turns on to recover the means 1 after the lapse of the specified time until the exposing beam reaches the photosensitive material 2 form the point of time when the means 1 is turned off. Namely, the light source means 1 is temporarily turned off only for the time corresponding to a specified scanning range in which the exposing beam from the means 1 reaches the photosensitive material 2. Therefore, the lighting time of the means 1 with respect to the number of scanning exposing times is shortened by the time corresponding to the unlighted time. Thus, the time for using the light source means 1 is made longer.

Title: Base frame structure of electronic timepiece
Inventor: FUJIMORI MOTOYUKI
IPC: G04B29/02
Filed: 1985-11-21
Abstract: PURPOSE:To reduce the thickness of a timepiece by deviating the pressing part of a circuit retaining member from the center of a crystal resonator unit so that said unit does not jump out of the top surface of a timepiece body. CONSTITUTION:The crystal resonator unit 3 is pressed by the circuit retaining member 15 from the position deviated from the center of the unit. The unit is fixed by means of a screw 13b via a negative terminal 16 of a battery and a circuit substrate 5 to a train wheel bridge 9 guided by a leg 14b of a base frame 1. The lower side of the unit 3 is housed, held and fixed into the recess of the frame 1. The recess is so formed that >=2 slopes including gently graded slope 1d and steeply graded slope 1e sandwich a base 1f. The unit 3 is supported by the slope 1e and base 1f. The unit 3 which is pressed and fixed off the center by the retaining member 15 receives the hither partial pressure to be exerted in the horizontal direction and is made easily disengageable from the recess but the horizontal component of force is absorbed by the steeply graded slope 1e. The base 1f of the recess is reinforced by providing the slope 1d. Since the top end of the retaining member 15 to press and fix the unit 3 is disposed within the thickness of the timepiece body, the thickness of the timepiece is reduced.

The thickness of the SiO2 film 15' on the polycrystalline silicon film 14 is thinned to approximately 1,000-2,000Angstrom  by etching the whole surface, and the SiO2 film 12' in 300-500Angstrom  film thickness on the upper surface of the silicon substrate 1 is all removed through etching. A novel SiO2 film 12 in 300-500Angstrom  film thickness is formed onto the silicon substrate 11 through oxidation in an oxidizing atmosphere at a high temperature (1,000-1,100 deg.C). Oxidation also progresses similarly onto the polycrystalline silicon film 14 at that time, and an SiO2 film 15 in 1,200-2,200Angstrom  film thickness is formed.
