Title: Air-fuel ratio control method
Inventor: AMANO MATSUO
IPC: F02D41/00
Filed: 1986-03-03
Abstract: PURPOSE:To improve accuracy of air-fuel ratio control by assuming a difference between a reference value and a manipulation amount obtained by proportional integration based on a deviation of air-fuel ratio obtained with an air-fuel ratio sensor from a target air-fuel ratio to be a learning amount and feedback-controlling the air-fuel ratio based on the learning amount and the manipulation amount. CONSTITUTION:When an engine is running, a fundamental fuel injection time is calculated from a suction air flow rate obtained with a suction air flow rate sensor 24 and an engine rpm. The calculated result is multipiled by a coefficient of set air-fuel ratio to obtain a fuel injection time for producing approximate target air-fuel ratio. And finally a fuel injection time is obtained so that the target air-fuel ratio is obtained by means of a feedback manipulation amount beta obtained with an air-fuel ratio sensor 142. Here, the manipulation amount beta is obtained by proportional integration operation process based on a deviation of an air-fuel ratio detection signal with the air-fuel ratio sensor 142 from the target air-fuel ratio. And assuming the difference between the manipulation amount beta and the reference value to be a learning amount corresponding to operating conditions, the air-fuel ratio is controlled according to the feedback of the learning amount and the manipulation amount beta.

Title: Correction system for color television luminance signal
Inventor: YUYAMA ICHIRO
IPC: H04N11/24
Filed: 1985-03-06
Abstract: PURPOSE:To reduce the deterioration of the high range components of brightness signals in the high quality image by converting output line type three prime color signals of the image pickup element into a luminance signal and two chrominance signals for bandwidth limitation in a color television transmitting and receiving system provided with a gamma correcting circuit at the transmitting side, changing these signals into different linear three prime color signals by a back conversion circuit and passing these signals through a gamma correcting circuit. CONSTITUTION:An encoder 4 and a decoder 7 of a correcting part execute conversion and back conversion between output signals R, G and B and Y, CW and CN of image pickup tubes I, II and III. The ranges of low-pass filters 5, 10 and 6, 11 are limited to the band width allotted in the transmission channel to the broad band chrominance signal and the narrow band chrominance signal. In this case, the chrominance signals above the chrominance signal range as to the correcting part output R', G' and B' are monochromatic as to the component above the chrominance signal range. As to the monochromatic signals, transmission becomes possible without damaging the luminance information even if encoding is effected after the gamma correction, so that the high quality information above the chrominance signal range may be reproduced in the receiving tube.

CONSTITUTION:In a procedure, an inverse exciting start in which an exciting current including an inverse excting and driving operation inverting an electricity-feeding operation without substantially including a suspension period is suppllees is performed (Step S1). Then, whether the number (n) of revolutions of a motor is larger than the first set number (M1) of revolutions or not is judged (Step 52). When the number (n) of revolutions is lower than the set number (N1) of revolutions, the procedure is returned to the setp S1, and the inverse exciting start is repeated. Then, a phase is shifted (Step S3), and, in succession, an electricity-feeling pattern supplying an exciting current is changed over (Step S4). A unipolar drive which supplies the exciting current to a single phase is performed (Step S5). In addition, whether the number (n) is larger than the steady number (N0) of revolutions of the motor or not is judged (Step S6). When the number (n) of revolutions is lower than the steady number (N0) of revolutions, the procedure is returned to the step S5, and the unipolar drive is continued and repeated.

Title: Moisture responsive thin film and manufacture thereof
Inventor: YOKOYAMA MASAO
IPC: H01C7/00
Filed: 1988-02-26
Abstract: PURPOSE:To improve a response speed by forming a thin film by involving an alkali metal to tin oxide and increasing a change in impedance due to water adsorption. CONSTITUTION:A thin film is formed with tin oxide involving alkali metal. Thickness of the thin film is of 0.02-5mum. The alkali metal is of at least one kind selected among lithium, sodium, and potassium. The content of the alkali metal is 0.1-500mol% with respect to tin. Here, once water is adsorbed on a tin oxide thin film containing the alkali metal, a water molecule is partly dissociated to release a proton. Since the amount of adsorption of water molecule changes in response to a change in relative humidity, proton concentration also changes in response thereto, producing an enough impedance change depending on the change in the relative humidity. Hereby, a response speed is improved.

Title: Throttle
Inventor: NOMURA YURIO
IPC: F16K1/22
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a throttle which can reduce noise generated in opening a throttle valve. SOLUTION: A valve plate 52 in a throttle valve is constructed of an upstream portion 48 which rotated upstream of intake air and a downstream portion 49 which rotates downstream of intake air with a rotation axis 47 as a boundary. A guide vane 50 is formed further upstream from the upstream portion 48 in a projecting part 46. The guide vane 50 having an upstream surface inclining toward intake air flow functions as a buffer member to block the intake air flow partially. Thus, the cross section for the intake air defined between the guide vane 50 and a passage wall gradually becomes small from the upstream to the downstream so that the pressure near the outlet(downstream side) of the guide vane 50 is reduced, resulting in less pressure difference caused at the space on the tip of the upstream portion 48.
