Title: Air-fuel ratio control device for internal combustion engine
Inventor: TAKAHASHI TOSHIHISA
IPC: F02D41/14
Filed: 1988-03-10
Abstract: PURPOSE:To prevent an air-fuel ratio control of low accuracy from being performed by stopping a feedback control and performing an open loop control when temperature of an oxygen concentration detecting means, detected by a temperature detecting means, is in a predetermined value or less. CONSTITUTION:An air-fuel ratio sensor 8 generates in its oxygen concentration cell part 23 electromotive force in accordance with a difference of oxygen concentration between the atmosphere and exhaust gas. This electromotive force is compared with reference voltage in an operational amplifier 27, and in accordance with the difference, a pump current Ip is supplied to an oxygen pump part 22 through a voltage current converter 28. This pump current Ip is converted into voltage by a current voltage converter 29 and output to an air-fuel ratio control circuit as an air-fuel ratio signal, and a feedback control is performed. Here in case of an element temperature, detected by a temperature sensor 26, being a predetermined value or less, the air-fuel ratio sensor 8 is decided not to perform its activation, and an open loop control is performed. Thus preventing an air fuel ratio control of low accuracy caused by an air-fuel ratio feedback control performed when an element is inactive, control accuracy can be enhanced.

Patent JP-H08256472-A (JP)
Title: Semiconductor pump circuit
Inventor: YOSHIDA MASAKO
IPC: G11C11/407
Filed: 1995-03-16
Abstract: PURPOSE: To enable the significant reduction of current required for boosting in at least two pump circuits to which input signals of opposite phases are fed, by causing a short circuit immediately before the input signals of opposite phases are inverted. CONSTITUTION: What is different from prior arts is as follows: Immediately before VIN and /VIN are inverted, a clocked inverter is turned off, and VPHI is brought into the HIGH level to short-circuit N1 and N3. After both N1 and N3 have become 1/2 Vcc, VPHI is brought into the LOW level to separate N1 from N3, and VIN and /VIN are inverted to turn on the clocked inverter. This makes it possible to halve the current passing when the inverter is inverted and thus reduce the current consumption. The effect of current consumption is most remarkable when the output potential OUT is close to the supply voltage Vcc.

IPC: B67D7/54
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a valve mechanism for recovering the oil vapor from a fuel tank by suction. SOLUTION: In a refueling nozzle 8 the valve shaft 45 of the main valve for driving a main valve body 27 open and closed serves also as a valve mechanism for opening and closing an oil-vapor suction passageway.

Abstract: PURPOSE:To detect all paper sheets to be entered into a tray by moving a side regulation board in the lateral direction of paper to a position where an entered paper can not be detected by means of a paper sheet detecting means upon completion of entrance of a sheet of paper. CONSTITUTION:Parallel step sections 2a, 2b are formed in the entering direction A of paper on the upper face of an intermediate tray 1, then side regulation boards 3, 4 having approximately C-shaped cross-section are inserted into respective step sections 2a, 2b to be movable laterally through a rack gear 8 bearing with a pinion gear 10 which is rotated by means of a motor 9. A paper detection sensor 5 is arranged on the upper face of the side regulation board 3. When the paper is entered, both side regulation boards 3, 4 are set such that the distance between respective inside faces 3a, 4a equals to the width of paper, and the entrance of paper is detected when the paper contacts against the paper detection sensor 5 under this condition. When a predetermined time has elapsed, the side regulation boards 3, 4 are moved to the outside so as to fall and store the paper onto the upper face of the intermediate tray 1.

Title: Image pickup device
Inventor: KAWAHARA HIDEO
IPC: H04N5/20
Filed: 1988-03-10
Abstract: PURPOSE:To eliminate a sense of disorder of a video image by compressing an image pickup signal depending on the compression characteristic in response to the output of the detection means so as to limit an output of a compression detection means. CONSTITUTION:An amplification factor of an inverse amplifier 105 is set to, e.g., -1/2 and the base-on voltage of a transistor 110 is adjusted by using an offset voltage of the inverse amplifier 105 so as to be 110% with the conversion of, e.g., an input image pickup signal and similarly, a limit voltage of a limiter circuit 107 is set to, e.g., 60% by the conversion of the input image pickup signal. Thus, when a peak value of the input image pickup signal is set to 110% or below, the input image pickup signal appears at an output terminal 103 as it is. When a peak value of the input image pickup signal is set to 110% or over, a compression start point is decided in response to the time constant of an integration device 106 and the peak value of the input image pickup signal, and the image pickup signal over the compression start level or over appears at the output terminal 103 while being attenuated by a ratio decided by the ratio of the 1st resistor 108 and the 2nd resistor 109. Thus, deformation in the image pickup signal caused in the input of a spot with high brightness is prevented.

Filed: 1978-05-15
Abstract: PURPOSE: To control air-to-fuel ratio of cylinders with use of a feedback control circuit, and to control others in the same proportion to cylinders on one hand side of the cylinders by providing an air-to-fuel sensor only on the exhaust system of the cylinders on one hand in an engine consisting of two cylinder gourps.  
     CONSTITUTION: An air-to-fuel sensor 5 is provided only on an exhaust pipe 3a of cylinders on one hand. A compensating control circuit 9 is given input of a signal of a feedback control circuit 6, when integrating output of an integrating circuit 62 increases, it yields low level, when it decreases, it yields high level, in short, integrating output means an output in which signals superimposed by anti-phase short wave-form signal output with average output of the integrating circuit 62 are given on a compensating circuit 7b on the other hand. In consequence, for example, in case where air-to-fuel ratio on the cylinders on one hand is going to be rich in the increase of integrating output C, air-to-fuel ratio on the cylinders on the other hand is to be lean without fail, which offsets the rotational fluctuating factor of the engine, and enables to repress the rotational fluctuation.

Title: Signal correcting device for magnetic head
Inventor: MATSUI YASUTAKA
IPC: G11B5/02
Filed: 1990-03-12
Abstract: PURPOSE:To allow the good use of a tape device even when a magnetic head of a medium sliding type constituted of a magneto-resistance effect element is worn by providing a means for measuring the DC resistance of the head, a means for storing the compared value of a predetermined resistance value and a means for reproducing the plural different signals of reproduction signals. CONSTITUTION:The output of a comparator 28 is low and changeover switches 24, 25 select a 1st preamplifier 22, which amplifies the read signal at an adequate amplification factor when the initial DC resistance to be used of the magnetic head 21 is low. The sectional area of the head decreases when the head 21 is worn on continuation of use and, therefore, the DC resistance value increases and the output of the comparator 28 attains a high level when the resistance value exceeds a prescribed value. The changeover switches 29, 30 select the 2nd preamplifier 23 which adequately amplifies the read signal at the low amplification factor. The long-term use without exchanging the head is executed in this way if the above-mentioned device is constituted in such a manner.
