Title: Air fuel ratio control method
Inventor: SAKURAI SHIGENORI
IPC: G01N27/41
Filed: 1982-04-05
Abstract: PURPOSE:To make it possible to very accurately control an air fuel ratio by adjusting the amount of fuel supply while properly changing the voltage to be applied to a sensor element part in responce to the target air fuel ratio and comparing the resultant output current from the sensor element part with the current at the target air fuel ratio. CONSTITUTION:A target air fuel ratio is set in a target air fuel ratio operating circuit within a control circuit 20, using the output signals from an air flow meter 24, a distributor 12 and a cooling water temperature sensor 12, and a basic fuel injection amount for an injector 30 is set in a basic fuel injection operating circuit. Said target air fuel ratio is converted into the target oxygen concentration, and thereby a current value (reference current value) corresponding to the target oxygen concentration is determined, according to the curve implying a prescribed applied voltage to a sensor-output current characteristic, in a reference current operating circuit. And, on the basis of this reference current value, the applied voltage is read from a memory, and said applied voltage is applied to an oxygen sensor 36. Further, following the deviation between the reference current value and the output current value of the sensor 36, the injection fuel amount is corrected.

IPC: G01S7/521
Filed: 1989-03-10
Abstract: PURPOSE:To improve S/N to improve the distance resolution by arranging an ultrasonic oscillator on the inside surface of the bottom of a closed vessel with liquid between them. CONSTITUTION:An ultrasonic oscillator 3 arranged on the inside surface of the bottom of a closed vessel 1 with the liquid for ultrasonic propagation between them is movably crowned with front end parts of plural oscillator cap screws 15 engaged with a cap screw holding plate 14 and is pressed and fixed to the inside wall of the bottom of the vessel 1 with an insulating member 18 between them by a bottomed cylindrical shoe 16 which is always energized toward the upper face of the oscillator 3 by a spring 17. Consequently, the vessel contact surface of the oscillator 3 flexibly profiles the inside surface of the bottom of the vessel 1 because a recessed part is filled up with the liquid though existing in the inside wall of the bottom of the vessel 1 and pressing of the oscillator 3 can be locally adjusted by oscillator cap screws 15 and the shoe 16. Further, the shoe 16 provided in front ends of screws 15 is moved in accordance with thermal expansion between the oscillator and the inside surface of the bottom of the vessel 1 due to the change of temperature to make the thickness of liquid uniform between the oscillator 3 and the inside surface of the bottom of the vessel 1, thus improving S/N.

Title: Thermal sensitive transfer material
Inventor: SATO HIROSHI
IPC: B41M5/42
Filed: 1988-03-09
Abstract: PURPOSE:To print with high density and good sharp feeling even on a recording medium having insufficient surface smoothness by incorporating heterogeneous structure particles in a thermal sensitive transfer ink layer on a support. CONSTITUTION:A thermal sensitive transfer material 1 is formed by forming a heat transfer ink layer 3 containing heterogeneous structure particles on a sheetlike support 2. Resin A is distributed on a whole area in the particles, and resin B having different glass transition point from that of the resin A is locally disposed at the center of the particle. Such particles are contained in the layer 3. Thus, when heat is once applied by heating means, such as a thermal head or the like to the ink layer, the resin B at the center is moved to the peripheral edge of the particle to accelerate the fusion-bonds of the particles thereby to provide suitable film strength, and to further improve adhesive properties to a recording medium. On the contrary, since a sharp feeling is maintained at a boundary between the heated part and the nonheated part of the ink layer, a sharp feeling is indicated.

IPC: H04B1/26
Filed: 1980-04-29
Abstract: PURPOSE:To prevent the lowering of mixture gain for a high band frequency and at the same time improve the image ratio, by connecting a coil in series to the collector of a grounded emitter transistor and thus cancelling apparently the junction capacity. CONSTITUTION:The coil L2 is connected between the collector of transistor Q and the joint between coil L1 and capacitor C4. With such insertion of coil L2, a series connection is secured to the junction capacity CC. As a result, a series resonance circuit comprising a series circuit of capacity CC, coil L2 and capacitor C4 is obtained. The resonance frequency of this case is C4>>CC and thus decided virtually by L2 and CC. In such way, a series resonance circuit of CC and L2 is substantially formed. As a result, the capacity CC can be apparently cancelled.

Filed: 1990-03-07
Abstract: PURPOSE:To eliminate the need for complicated program control even in the case of a fault of a secondary switch by omitting control of a redundancy switch from a switch controller and a selecting drive control of the switch between the controller and the switch. CONSTITUTION:A drive switching circuit 50 always transfers and outputs the output of a controller 40 to a switch as it is and selects one of faulty secondary switches to a redundant 2n-th secondary switch 22n upon the receipt of a secondary switch fault notice. Thus, an address relating to the faulty secondary switch is outputted while being converted into an address of the redundant 2n-th secondary switch 22n. The control of outgoing terminals of primary switches 11-1N/n and incoming terminals of ternary switches 31-3N/n is selected into the control of the terminal connecting to the 2n-th secondary switch 22n from the faulty secondary switch. Thus, even in the case of the secondary switch fault, no complicated program control is required.

Title: Heat-sensitive transfer paper
Inventor: AKISHIMA HIDEO
IPC: B41M5/26
Filed: 1981-04-17
Abstract: PURPOSE:To prevent the production of a change in size of a base paper due to humidity and heat, by using a paper, having a density of 0.76-1.05g/cm<2>, as a base paper of a heat-sensitive transfer paper. CONSTITUTION:In a heat-sensitive transfer paper, in which thermal fusing ink is applied on a base paper, a paper, having a thickness of 9-25mu, a density of 0.76-1.05, especially 0.76-1.0g/cm<2>, is used as the base paper, and this improves stability on size, being influenced by humidity and heat, of the base paper of the heat-sensitive transfer paper to prevent the production of wrinkles and curl. Compared with a paper of a high density, a paper of a low density of 0.76-1.05g/cm<2> is excellent in stability on size, which is related to a gap size. Or, elongation of a paper, having a low density, is absorbed in a gap to prevent the elongation from propagating, which results in preventing size from increasing. Finally, the thickness of the paper is preferably 9-25mu in terms of thermal energy and mechanical strength.
