Title: Rgb video amplifier system incorporating blanking and luminance conrol tracking
Inventor: RONARUDO DABURIYU PEIJI
IPC: H04N5/18
Filed: 1992-01-23
Abstract: PURPOSE: To extend an operating range by providing a DC re-insertion circuit to clamp a DC bias, so as to suppress a saturation operation of a video amplifier. CONSTITUTION: During a blanking period, a switch 39 is thrown to the upper position for applying a bias to an amplifier 37, thereby generating a positive blanking pulse to the cathode of a CRT 10. The switch 39 is thrown to the lower position for a blanking pulse interval to allow a video circuit to be configured. When a switch 36 is operated by the clamp pulse, a capacitor 33 is charged so that an inverting input and a noninverting input are made identical by a ga amplifier 35 through the adjustment of a level of a cut-off adjustment control 18 and a black-level control 42. Thus, a good control is attained by keeping a level of the blanking pulse in the cathode of the CRT 10 higher than the black level, and a lock state is avoided without saturating the amplifier 11.

Title: Decimal arithmetic device
Inventor: NAGURA KUNIHIRO
IPC: G06F7/38
Filed: 1982-01-26
Abstract: PURPOSE:To improve the performance, by detecting zero by hardware, and omitting a step for searching zero, when transferring an operand data to a bufffer register, in a data processor for processing a decimal data. CONSTITUTION:In a data processor which is controlled by a microprogram and processes a decimal data, when an instruction is fetched from a main memory and it is recognized that it is a decimal operation instruction, an operand data is fetched to a data buffer 11, and is transferred to a buffer register 13. During the time, a zero deteting circuit 18 checks at every transfer whether a 1 digit data of 4 bits which is tansferred is zero or not, and unless it is zero, a signal NZEROI is made active. In the course of transfer, when the signal NZEROI is active even once, a flip-flop 19 is reset. By a micro-instruction, values of a flip-flop 18 and an effective length register 20 are read, and unless all are zero, the value of the effective length register 20 is loaded as length for the operation, to a register 16.

The catalyst particles are thereafter separated by a cyclone 15 and are circulated from a flow passage 16 to the thick layer. The once recovered high-pressure steam is cyclically used from a flow passage 18.

IPC: G11B21/21
Filed: 1993-01-27
Abstract: PURPOSE:To measure a variation in a floating amt. of a magnetic head under operation in an actual magnetic disk device. CONSTITUTION:A signal of a constant amplitude and a constant frequency is recorded with some number of waves in each sector of all tracks on a disk 2, and the recorded signal is regenerated by a head 1 and a read/write circuit 14, and is fullwave-rectified and integrated in each sector and peak-held by circuits 21-23. In order to equalize integrated peak values for individual sectors in all of the sectors when a floating amt. is stable, the number of waves of the signal in each sector is modified and recorded, and this operation is repeated. By this method, effect of a variation in positional sensitivity of the disk is eliminated, and a regenerated output for a constant floating amt. can be constant in all the recording areas (sectors). When the regenerated output is varied at the time of measurement, since this change is purely based on a variation in a floating amt., the floating amt. can be calculated by using a relational expression of the regenerated output and the floating amt. from the regenerated output change.
