Title: Focus servo gain adjusting circuit for optical disk reproducing device
Inventor: HAYASHI YASUHIRO
IPC: G11B7/095
Filed: 1986-08-12
Abstract: PURPOSE:To execute the correct focus servo gain adjustment for a short time by oscillating an objective lens near a focus point position. CONSTITUTION:A focus error signal FE from a subtracter circuit 12 is supplied to a lens driving signal generating circuit 15. The generating circuit 15 inverts the polarity of a lens driving signal each time of a focus error signal is supplied. Thus, in one cycle period of a lens driving signal, since the objective lens passes through a focus point position plural times, plural focus error signals FE can be obtained, the level detection of the focus error signals FE can be correctly executed by an FE level detecting circuit 19 and consequently, the correct focus servo gain adjustment can be performed for a short time.

Title: Control device for air-fuel ratio
Inventor: KITAHARA TAKESHI
IPC: F02D41/00
Filed: 1983-10-07
Abstract: PURPOSE:To enable control of an air-fuel ratio to a target air-fuel ratio by discriminating whether the air-fuel ratio is larger or smaller than the target air-fuel ratio by the output from the 1st oxygen sensor and discriminating the deviation thereof from the target air-fuel ratio according to the flush current value to the 2nd oxygen sensor. CONSTITUTION:Whether an air-fuel ratio is larger or smaller than a target air- fuel is discriminating by the output Vs1 of the 1st oxygen sensor 20. Whether said ratio is to be corrected for an increase or for a decrease is determined according to the result of the discrimination. On the other hand, the magnitude of the deviation of the air-fuel ratio from the target air-fuel ratio is judged by detecting the magnitude of the flush current I2 to the 2nd oxygen sensor 21. The fuel can be therefore gradually increased or decreased when the deviation of the air-fuel ratio from the target air-fuel ratio is small and the air-fuel ratio can be controlled always to the target air-fuel ratio without deviating the air-fuel ratio more than necessarily from the target air-fuel ratio. If the air-fuel deviates considerably from the target air-fuel ratio on account of fuel cut, etc., the fuel can be quickly increased or decreased, by which the air-fuel ratio is controlled quickly to the target air-fuel ratio.

Title: Page printer
Inventor: TSUCHIDA TOSHIYA
IPC: G03G15/00
Filed: 1989-07-21
Abstract: PURPOSE:To precisely detect toner residual and to display a toner residual alarm by controlling the toner residual from printing density and printed data volume. CONSTITUTION:A printed data volume control part 4 calculates a printing area of a printed page from the type and volume of received data and controls it. A toner residual control part 5 calculates toner consumption of the printed page from printing density obtained from a printing density controller 6 and from the printing area obtained from the printed data volume control part 4, and controls a cumulative toner consumption. When it reaches a critical value, toner residual alarm display part 7 displays the toner residual alarm. Consequently, the error between an actual toner residual and an estimated toner residual, which arises from a change in printing density and variance in printed data volume, can be minimized.

Abstract: PURPOSE:To improve cross color without the distortion of a waveform by calculating the amplitudes of adjacent points at an interval, which is the integer multiple of 1/2 for a chrominance subcarrier waveform, in a video signal calculating the plural minimum values of the combination of the two points out of these points, and calculating a maximum value out of the minimum value of each combination as mentioned above. CONSTITUTION:When the component of an inputted chrominance subcarrier band is a signal like a waveform (a), the signal is delayed by 140nsec as a half waveform in delay circuits 12 and 13 and the output signals of waveforms (b) and (c) are obtained in outputs of the delay circuit 13 and an inverter 14. When a reference potential is defined as zero, in an output F point where the minimum value is selected out of a reference level 19 signal and output signals (d) and (e) of MAX computing elements 23 and 24, a waveform (f) is obtained as the lower half waveform of a MIN (d, e). Thus, in an output terminal 31, signals (f) and (i) are added by an adder 29 and afterwards, the added signal is inverted by an inverter 30. Then, the signal of a waveform (j) is obtained. When the waveform (j) is observed, a chroma component is outputted as it is without waveform distortion.

Title: Variable counting circuit
Inventor: OOTSUKA YASUAKI
IPC: H03K23/66
Filed: 1990-07-18
Abstract: PURPOSE:To decrease the capacity of a ROM by dividing an output of a counter into two as high and lower-order bits, giving the high-order bit to a selector and the low-order bit to the ROM respectively and selecting an output of the ROM by the selector. CONSTITUTION:A data of a ROM 6 is set so that a result of discrimination is logic '1' when an output of a counter 5 exceeds a threshold level. That is, the result of discrimination is set to logic '1' when an output of the counter 5 exceeds the threshold level while output bits of the ROM 6 selected by the high-order (l) bits are combined with the address depending on the low-order m-bits. Output n-bits of the counter 5 is divided into high-order (l) bits and low-order m-bits, the low-order m-bits enter the ROM 6 as its address and the high-order (l) bits are used for a select signal of the selector 7. Then the m-bit ROM 6 and the (l) bit selector 7 act like an (m+l) bit ROM. Since the input bit number of the ROM 6 is decreased, the capacity of the ROM is reduced.

Title: Optical axis adjusting device of head lamp
Inventor: SAITOU KUNIHIRO
IPC: G01M11/06
Filed: 1983-10-14
Abstract: PURPOSE:To reduce a temperature variation and a secular change by using a combination of switches in order to detect a direction of an optical axis, and using a relay circuit in order to rotate a motor forward and backward. CONSTITUTION:In case a load is applied to a vehicle, a selecting switch 7 is switched by selecting a scale by a degree of the load in order to prevent an optical axis of a head lamp from turning upward. When ''0'' is switched to ''1'', a + current passes through a reverse-current preventing diode 3 and 10, a relay Ry2 and Ry4 are turned on through a switch B and B', and a contact P2 and P4 are switched. A current iB and a current iB' flow to a right motor 4 and a left motor 11, respectively, motors 4 and 11 rotate, and the optical axis of head lamps 6, 13 is varied. A slide contact of an optical axis detecting switches 2 and 9 moves toward ''1'' from a position ''0'', and when it reaches ''1'', switches B and B' become off, therefore, relays Ry2 and Ry4 become off, contacts P2 and P4 are reset, and motors 4, 11 stop. In this state, when the selecting switch 7 is switched to ''1'' from ''0'', the optical axis is varied to a position of ''1''.
