Patent JP-S5812432-A (JP)
Title: Integrated circuit device
Inventor: SUGAWARA MITSUTOSHI
IPC: H04B1/10
Filed: 1982-06-28
Abstract: PURPOSE:To eliminate the influence of voltage fluctuation due to power source impedance by converting the output signal of a signal processing circuit into a current, and then supplying this current to a load resistance connected to a reference potential at one end. CONSTITUTION:One output signal of a demodulating circuit 16 is converted into a current by the current mirror circuit composed of a diode 351 and a transistor TR352, and the current is supplied to a load resistance 319 connected to an earth terminal 308 at one end. The other end of this resistance 319 is connected to an output terminal 317. Similarly, the other output of the circuit 16 is supplied to the current mirror circuit composed of a diode 353 and a TR354, and is converted into a current, which is supplied to a load resistance 321 connected to the terminal 308 at one end and to an output terminal 318 at the other end. In this constitution, voltages developed across the loads 19 and 321 are insensitive to fluctuation in power voltage. Therefore, even if the potentials at terminals 5 and 7 vary with the internal resistance 2 and fine resistance of a power source 1 during switching, the DC components of the voltage at output terminals 33 and 34 never vary.

Title: Tracking servo-drawing-in unit of optical information reader
Inventor: OKANO TAKASHI
IPC: G11B7/085
Filed: 1978-09-09
Abstract: PURPOSE: To perform stably servo-tracking by closing a servo-loop at the point in time when a relative speed between search irradiation light and a track decrease down to a minimum through the eccentric rotation of a magnetic disc and a regenerated optical signal increases up to a maximum.  
     CONSTITUTION: When irradiation light moves in a direction crossing tracks Y of magnetic disc 8 for a search for a track, track position error voltage A corresponding to reflected light is developed through a photo detecting element to generate sine-wave signal C, corresponding to a relative speed between the irradiation light and disc turning eccentrically during a single rotation by differentiating circuit 21 and envelope detection circuit 22. Then, when this signal is applied to comparator 23 applied with a reference voltage and the relative speed decreases down to its minimum, the output of comparator 23 is held at a high level. On the other hand, when a regenerated optical signal through the envelope detector corresponding to a shift in track reaches to a fixed value, the output of comparator 25 is inverted into a high level. Therefore, closing a servo-loop when comparators 23 and 25 generating high-level outputs through OR circuit 26 disallows the irradiation light to jump over track 7, thereby performing stably servo-tracking.

Abstract: PURPOSE: To prevent electrodes from being separated by a method wherein a roughened surface is formed on the form of the surface of the lower electrode layer of a photoelectric conversion device of a structure, wherein the lower electrode layer, a photoelectic conversion semiconductor layer and a transparent upper electrode layer are laminated in order on a flexible and insulative substrate, and the mean thickness of the roughened surface and the mean interval between the roughened mountaines of the roughened surface are formed within a prescribed value. CONSTITUTION: Ag is subjected to DC sputtering in Ar gas on an insulative and flexible substrate 1 to form a lower electrode layer 2. A substrate temperature at the time of the sputtering of the Ag is controlled at 200 to 400 deg.C to form a roughened surface 8, which has a mean film-forming thickness of 250μm or thinner, the mean interval of 150 to 1000nm between roughened mountains and a difference of altitude of 50 to 150nm. After an N-type a-Si layer 3, an I-type a-Si layer 4, an I-type u-SiO layer 5 and a P-type u-SiO later 6 are deposited in order on the layer 2 by a chemical vapor deposition method, the layer 6 is subjected to RF sputtering to deposit an indium-tin oxide on the layer 6 and a transparent upper electrode layer 7 is formed.  Thereby, separation of the electrodes and a short-circuit between the electrodes are prevented from being generated and the characteristics of a photoelectric conversion device are improved by a light scattering effect.

Title: Nonlinear ad converting circuit
Inventor: AKAGIRI KENZOU
IPC: H03M1/38
Filed: 1982-06-28
Abstract: PURPOSE:To prevent the reduction in resolution, by feeding back a component of a pass band or below of an AD converter in a feedback signal to a comparator after carrying the digit of the component by one in the AD converting system having a nonlinear AD converter in a negative feedback loop. CONSTITUTION:An output signal of the nonlinear AD converter 2 is inversely amplified at an inverse amplifier 4, after only the frequency component of the pass band or below of the converter 2 is filtered at a low-pass filter 5, the result is summed with the output signal of the converter 2 at an adder 6. Thus, a signal inputted from the adder 6 to the comparator 3 is increased for the rate of feedback of a low-frequency component among the rate of feedback of a feedback system. Thus, since a DC offset of the comparator 3 is canceled with the negative feedback system having frequency-gain characteristics, the error of AD conversion is decreased and the accuracy of quantization relating to a small level analog input signal is improved especially.

Filed: 1983-06-20
Abstract: PURPOSE:To improve volumetric efficiency by providing projections, inserted in an intake port and an exhaust port respectively when a piston is in the top dead center, on the top surface of the piston. CONSTITUTION:Projection parts 36, 37, provided on the top surface of a piston 20, are inserted respectively in an intake port 13 and an exhaust port 14 at the end of a process of compression for a cylinder 3 of supercharge.

Inventor: EGUCHI TAKAAKI
IPC: B62D7/14
Filed: 1989-05-02
Abstract: PURPOSE:To enable a driver to feel a presentiment of grip limits of a tire by changing a proportional constant related to steering value and a differential constant related to steering speed so as to come nearer to a characteristic when yaw damping is in rear-wheel nonsteering in response to lateral acceleration in a vehicle. CONSTITUTION:Each signal out of a steering angle sensor 18 detecting a steering angle, a car speed sensor 19 detecting car speed V, and a lateral G sensor 20 detecting lateral acceleration G in a vehicle is inputted into a controller 17. Then, steering angle speed is operated, and a differential constant tauconformed to the car speed V and a proportional constant K conformed to the car speed V and the lateral acceleration G are looked up in a table. Next, the proportional constant K or the differential constant tau is changed according to the lateral acceleration G, and it is gradually decreased in proportion as going toward a limit area via a nonlinear area from a linear area. Accordingly, a yaw rate gain characteristic at each area comes nearer to a characteristic at time of rear-wheel nonsteering in proportion as going toward the limit area. With this constitution, a driver is able to predict grip limits of a tire, thus he can quickly deal with a car body behavior change.
