CONSTITUTION:The position of a pickup provided in an optical system 9 on the magneto-optical disk 1 rotated and driven with a fixed angular velocity is detected by a processor 36 provided in a channel clock forming device 2. Then, by a gain correction circuit 31, the level of phase error detection data showing the phase error of the channel clock for the servo pattern detection data formed by a phase generator 23 is corrected based on the detected position of the pickup. The phase error detection data are supplied to a VCO 35 through a D/A converter 33, a phase compensation circuit 34. By the VCO 35, the frequency of the channel clock outputted according to the phase error detection data is varied.

Abstract: PURPOSE: To prevent the generation of a local potential distribution on a base by arranging a resistor between one end of a base support member and the other end to be connected to an earth. CONSTITUTION: A base 100 is formed of a glass base 101, a metal wiring for connecting a TFT array, or signal line or scanning line 102, an orientation film 103, a liquid crystal 103, a seal layer 105, and a color filter 106. A base support member 110 is formed of one end 111 of a L-shaped base support member 110, the other end 112 of the base support member 110 connected to an earth; and a resistor 113 arranged between the one end 11 and other end 112 of the base support member 110. Thus, when the base 100 is charged with a charge (a), a charge (b) having the reverse polarity to the charge (a) is supplied through the base support member 110. Consequently, the base 110 is laid in the macroscopically neutralized charged state, or a substantially zero potential state where the charge (b) is removed, and the generation of a trouble by electrification can be reduced. The resistance value of the resistor 113 is desirably 50KΩ or more and less than 1GΩ.

IPC: H04M1/00
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a transfer telephone set which eliminates personal payment of a speech charge of a caller side. SOLUTION: When an incoming call is received and a bell signal is detected, a caller information detection means 3 in the transfer telephone set acquires a telephone number of a caller.

When a reply is obtained from the transfer destination, the 1st telephone line 1 and the 2nd telephone line 9 are connected directly, to connect the speech state between the caller called at first and the transfer destination. Thus, the payment of the speech charge by the caller side is eliminated.

Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of a system bus by setting a write latency variable in accordance with the CAS latency of a clock synchronization type memory. SOLUTION: In an operation at the time of setting every CAS latency CL, read latency and write latency to 2 and a burst length BL to 4, a write command Write (a), a read command Read (b) and a write command Write (c) are respectively issued at a first cycle, a second cycle and a sixth cycle as commands COM in synchronization with a clock signal CLK, In the operation of this continuous write operation-to-read operation-to-write operation, since the write latency and the read latency are both 2, an idle time is not generated on buses of input-output data I/O even at the time of the write operation-to-the read operation. Moreover, an interruption and a high impedance control in the course of a burst read are made unnecessary in the read operation-to-the write operation.

Title: Optical flip flop
Inventor: YANASE TOMOO
IPC: H01S5/026
Filed: 1987-02-16
Abstract: PURPOSE:To remove crosstalk at the time of optical coupling and to execute integration by using optical thyristors for radiating laser beams as an element for an optical flip flop (FF). CONSTITUTION:The optical thyristors 17, 18 and photodetectors 19, 20 are integrated on a semiconductor substrate 36. When a trigger beam 11 is made incident upon the thyristor 17, the thyristor 17 executes laser oscillation because it is provided with resonance structure based upon the end faces 22, 23 of resonators and double hetero structure. A part of the laser beams is optically coupled with the photodetector 19. Consequently, voltage impressed to the photodetector 19 and the optical thyristor 18 is reduced and the thyristor 18 is turned off. When trigger beams 12 are made incident upon the thyristor 18, the thyristor 18 executes laser oscillation and a part of the laser beams is optically coupled with the photodetector 20. Consequently, current is allowed to flow into the detector 20, the voltage impressed to the thyristor 17 is dropped and the thyristor 17 is transferred to off. Consequently, an RS type FF can be formed, crosstalk can be reduced because the output beams and coupled beams are laser beams, and the beams can be easily coupled with another FF.

Abstract: PURPOSE:To reduce time for moving image analysis and image compression and the cost of a hardware or the like by detecting a scene change point corresponding to the two kinds of differential data for a certain frame and frames with fixed width positioned before and behind that frame. CONSTITUTION:Among transformed data obtained at a DCT part 12, the DC component coefficient of that block is inputted by a DC component arithmetic part 16, after those coefficients are simultaneously added, they are divided with the number of blocks so as to calculate an average luminance value in the entire frame. The calculated value is transmitted to an inter-frame difference part 18 as it is and temporarily stored in an arithmetic result storage part 17a at a storage part 17. The difference part 18 calculates difference between the average luminance value transmitted from the arithmetic part 16 and an average luminance value for preceding one frame read from the storage part 17a. The calculated inter-frame difference is stored in a differential result storage part 17b for each frame number. Since the storage part 17b stores the inter-frame difference totally for the 61 frame of that frame and respectively preceding and following frames 30 while always updating it, the differential result stored in the storage part 17b is read to a detection part 19 and here, the scene change point is detected by any statistical method.
