Title: Air-fuel ratio control method for internal combustion engine
Inventor: YAMAMOTO TOSHIO
IPC: F02D41/14
Filed: 1990-04-03
Abstract: PURPOSE:To improve controllability by determining a learning value based on a value in the case when a feedback control value is switched from an increase side to a decrease side in a plurality of learning zones which correspond to respective engine loads and a value in the case when it is reversibly switched. CONSTITUTION:A main O2 sensor 6 is arrange upstream from a Maniverter 14 which is a catalyst converter, and on the other hand, sub O2 sensor 7 is arranged downstream from the Maniverter 14, and the output signals thereof are inputted to an electronic controller 9. A basic injection quantity TP is then corrected by an air-fuel ratio feedback compensation factor FAF based on the feedback signal (f) of the main O2 sensor 6 so as to determine a final electrification time T. In this case, in a leaning zone of an engine load in which the initial value and the required value of a feedback control value are close to each other, the feedback control value is rapidly transferred to the vicinity of the required value, so that the learning value may be determined based on a control value which varies in the vicinity thereof. In the case when the engine load is varied, an air-fuel feedback control is carried out with the corresponding learning value of the engine load considered as its starting point.

IPC: H01S5/023
Filed: 1982-05-28
Abstract: PURPOSE:To extend operating life of semiconductor laser element by mounting a semiconductor laser element to the area near the center of a submount and by giving an inclination to the one side surface of the submount so that the edge of submount is not irradiated with the laser beam. CONSTITUTION:A submount 7 is composed of molybdenum or silicon and is brazed to a step 6 consisting of copper or iron through a brazing material 8. A semiconductor laser element 9 is brazed to the area near the center of mount 7 with a brazing material 10 and the one side end of submount 7 is the inclined surface 7a being cut at the angle of at least 30 degrees for the bottom surface and is coupled at the contact position with the reflecting surface 9a. Moreover, since the lower end of inclined surface 7a is coupled to the edge of stem 6. Therefore, if a semiconductor laser element 9 is placed on the area near the center of submount 7, when it emits the laser beam, the stable laser beam can be obtained without irregular reflection of laser beam. Since a semiconductor laser element 9 is coupled to the area near the center of submount 7, difference of line expansion coefficient to the semiconductor laser element 9 is reduced, suppressing the generation of strain.

Abstract: PURPOSE:To improve the performance of a photosensor and to reduce its cost by providing a metallic film on the flank of a light receiving element while the element is still in a chip shape, and carrying out a light shielding treatment. CONSTITUTION:A light emitting element 1 and a light receiving element 2 are arranged on a substrate 3 formed of a printed board, etc. At this time, the element 1 is arranged while still in the semiconductor chip shape, but the metallic film 2a of aluminum, etc., is formed on the flank of the chip by vapor deposition, etc., and the light shielding treatment is carried out. Consequently, the element 2 has no light receiving sensitivity in its flank direction and even if the element 2 is arranged on the substrate 3 nearby the element 1, it is not affected by direct light from the element 1, so that the elements 1 and 2 are arranged on the substrate 3 closely to each other. Thus, the photosensor is reduced in size and cost.

Title: Rotary transformer
Inventor: KAJINO OSAMU
IPC: H01F38/14
Filed: 1988-04-12
Abstract: PURPOSE:To reduce crosstalk between adjacent core pairs by a method wherein constitution is made by a number of coil pairs consisting of a rotor side coil and a stator side coil which face each other and a conducting material or a superconducting material approximately as large as a facing surface located between the facing surfaces of the core pairs. CONSTITUTION:Signal is transmitted when flux in which a current flowing in a rotor side coil 12a induces electric current to a stator side coil 11a. However, since a superconducting material 17 located between the rotor side coil 12a and a rotor side coil 12c shuts flux generated in the rotor side coil 12a, signal is not induced to the rotor side coil 12c preventing crosstalk from occurring. Locating the superconducting material between a rotor core 14a and a rotor core 14b to form them in one piece can reduce crosstalk occurring between a core pair consisting of a rotor core 13a and a stator core 14a and a core pair consisting of a rotor core 13b and the stator core 14b to extremely small amount.

IPC: H04B10/50
Filed: 1990-04-04
Abstract: PURPOSE:To decrease the size of a photodiode for dark current generation by increasing the transfer impedance of a reference voltage circuit larger than the transfer impedance of an amplifier circuit. CONSTITUTION:An amplifier circuit 2 consists of two transistors(TRs) 7, 8, and three resistors Rc1, Re1, Rf1, a reference voltage circuit 4 consists of two TRs 9, 10, and three resistors Rc2, Re2, Rf2 and the relation of Re2=Re1, Rf2=2XRf1, and Rc2=2XRc1 exists. Assuming Id1 as the dark current of a photodiode 1, and Id2 as the dark current of a photodiode 6, then a DC output level V1 at non-signal and a reference voltage V2 by the dark current are increased respectively by DELTAV1=Id1.Rf1, DELTAV2=Id2.Rf2. In order to keep the relation of DELTAV1=DELTAV2, since the relation of Rf2=2XRf1 exists, the relation of Id2=Id1/2 exists, and since the Id2 is enough to be Id1/2, the area of the photodiode 6 is a half the area of the photodiode 1. Thus, the area of the photodiode for generating a dark current is decreased.

Title: Water feeder for automatic ice-making device
Inventor: KONISHI HIROSHIGE
IPC: F25C1/24
Filed: 1993-04-16
Abstract: PURPOSE:To shut out bacteria in the air by disuse of a water-receiving part so as not to expose water to air. CONSTITUTION:When a solenoid 57 is not in action, a cone 61 is down, a spring 75 is in its elongated state, and an interlocking shaft 69 is at its lowered position. In this state an inflow hole 65 is open; water flows from a water tank 59, through a activated carbon 73, and into an upper case 72; from thence through the inflow hole 65 and with an outflow hole 67 closed the water enters a fixed-quantity chamber 64 until this chamber becomes full. When subsequently the solenoid 57 works, the cone 61 is lifted and the inter locking shaft 69 rises to close the inflow hole 65 and open the outflow hole 67 so that the water inside the fixed-quantity chamber 64 is discharged through the outflow hole 67 and made to flow through a water-feeding channel 63 to an ice-making dish 56. All this thus takes place in the water tank 59, which is closed and keeps the water unexposed to the outside air, so that bacteria suspended in the air are shut out from the entry and there are virtually no bacteria occurring in the water. A cap 70 has a diameter which is large enough to allow a hand through so that the inside of the water tank 59 can be cleaned easily.
