Title: Clock synchronous circuit
Inventor: YOSHIDA YASUTSUNE
IPC: H04L7/027
Filed: 1985-05-28
Abstract: PURPOSE:To obtain a circuit obtaining a clock signal with less jitter without using a limiter circuit and realized economically with a small circuit scale by applying a narrow band filtering to an output being nonlinear control of an input signal and controlling a voltage controlled oscillation means with an output being the sampled output of the filter output. CONSTITUTION:A clock component is outputted from the tank circuit 204 of a clock synchronous circuit 21. The output is adjusted for a DC voltage by using a bias voltage Vb, sampled by a clock signal C2 at a flip-flop 211 and when the sampling value is larger than the threshold value of flip-flop 211, the output at an output terminal Q goes to 1 and when smaller, the output goes to 0. When the input at the input terminal D changes to the states (a-c), the output of the output terminal Q shows the phase comparison characteristic representing the relation of phase between the input at the input terminal D and the clock signal C2. Thus, the signal is used as the control signal of the voltage controlled oscillator 208 via a low pass filter 207, then the clock synchronous circuit 21 acts normally like the clock synchronus circuit.

Title: Semiconductor laser
Inventor: YUASA TSUNAO
IPC: H01S5/00
Filed: 1990-04-27
Abstract: PURPOSE:To stabilize a fundamental transversal mode and to reduce a threshold value by a method wherein the constitutive element of a quantum well structure in an active layer in an oscillation region is made partly different from that in other regions. CONSTITUTION:An n-type AlGaAs clad layer 2, a quantum-well active layer 3, a p-type AlGaAs clad layer 4 and a p-type GaAs cap layer 5 are grown sequentially on an n-type GaAs substrate 1. When the quantum well of the active layer 3 is grown, trimethylindium is used as a raw material which contains In, Ga or As. The growth temperature of only a stripe region 10 is set selectively at 700 deg.C or lower only when the active layer is grown, and the growth temperature in regions other than it is set at a high temperature of 750 to 800 deg.C. When the growth temperature is at 750 to 800 deg.C, In is disconnected from a substrate and is hardly taken in at an epitaxial growth operation. On the other hand, Al, Ga and As are taken into a growth layer at the temperature. Consequently, when the active layer 3 is grown at a temperature distribution, an InGaAs quantum well is formed only in the stripe region 10, and a GaAs quantum well is formed in a region adjacent to the region 10.

Title: Charged program service system of two-way catv system
Inventor: FUNAMOTO KAZUO
IPC: H04N7/16
Filed: 1982-06-30
Abstract: PURPOSE:To reduce a load on a center controller, by informing a viewer that a selected program is charged if the program is to be charged, and starting charging processing according to answering operation by the viewer. CONSTITUTION:When the viewer presses one of charged channel keys on a key pad 520 to request a charged channel, a terminal device 500 sends charging information on it to a centerl controller 110 and the charging information is stored in the memory in the terminal device 500 as well. In this case, if the charged channel is requested again, the charging information is prevented from being sent to the center controller 110 again. Consequently, the load on the center controller 110 is reduced. When the terminal device 500 requests the charged channel and the channel is uncharged, the viewer is informed that the channel is charged, and the charging is started after the intention of the viewer is confirmed. Consequently, only when real charging is performed, the charging is reported, so the viewer is prevented from being offered the service over the charged channel by mistake and vaguness about whether the charging is done double or not is eliminated.

IPC: G11B20/10
Filed: 1986-05-20
Abstract: PURPOSE:To make it possible to heighten speed of processing by reading ID information of an ID part of a file according to the result of detection when reading and writing the file. CONSTITUTION:After reading and writing data in a file, a controlling section 8 makes a disk change flag off at all times, and starts a timer 9.

Thereby, at the time of file changing, ID information of the ID part of a changed file is read always. On the other hand, when continuous reading and writing are requested, ID information of the ID part is read only at the beginning of the request, and thereafter, data are read from the file without reading ID information to the file.

Title: Single cylinder hydraulic buffer
Inventor: HAYASHI MAKOTO
IPC: F16F9/32
Filed: 1987-05-12
Abstract: PURPOSE:To accomplish smooth operation of a hydraulic buffer in a simple constitution by providing a plurality of main lips, a dust lip and a covering element which are fitted to the outer surface of a core and integral with a free piston sliding in a tube of the hydraulic buffer. CONSTITUTION:A free piston 10 is brought into contact with the inner peripheral surface of a tube 1 through two main lips 17, 18, so that inclination centering around the shaft center is prevented not to cause disadvantages such as abnormal friction with the inner surface of the tube 1, seizure due to the abnormal friction and so on. Foreign matter can be effectively prevented from entering a sliding surface by a dust lip 19. If internal pressure in an oil chamber 3 changes, an elastic film 20 is first sagged, so that a piston provided in the oil chamber 3, to which a rod is connected, is smoothly moved and the internal pressure of the oil chamber 3 is further changed. When the force applied to the free piston 10 becomes more than the maximum frictional force with the tube 1, the free piston 10 starts to move. Accordingly, the movement of the whole buffer can be smoothed.

Filed: 1994-05-27
Abstract: PURPOSE:To attain zooming keeping focusing without looking over an object by selecting a size of a range finding frame during zooming in response to a state of the range finding frame in the AF control before the zooming. CONSTITUTION:A gate circuit 111 passes through an image pickup signal only corresponding to a focus detection area (range finding frame) in which a set focal is matched to a predetermined position in a screen from an image pickup signal outputted from an AGC circuit 107. Then the gate is open to the image pickup signal being an output of the circuit 107 only for an output period of the signal corresponding to the range finding frame and the gate is closed for a period other than the output period to interrupt the signal. Thus, the switching timing is controlled by a microcomputer 118 to vary the position and size of the range finding frame in the screen. Thus, the range finding frame in zooming is made proper and looking over of an object attended with a range finding frame changeover or missing of the object in the screen due to a change in a field angle is prevented.
