Title: Video signal processing unit, video signal processing method, video signal recording/reproducing device and recording medium
Inventor: KORI TERUHIKO
IPC: H04N5/913
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To reduce disturbance on display by a television monitor and to ensure copy prevention effect in the processing of an analog video signal. SOLUTION: A burst signal whose phase is partly inverted is arranged to a (5n+0)th line and (5n+2)th line. A burst correction signal with a larger amplitude is arranged to a (5n+1)th line and (5n+3)th line. A regular burst correction signal is arranged to a (5n+4)th line. The 5 lines are used for a macro block and plural macro blocks are used to form a block for copy prevention signal. Since the inverted burst signals are arranged intermittently, the frequency in the unit of lines is increased and no image disturbance is caused on a monitor with a narrow automatic phase control circuit(APC) frequency response range but image disturbance is caused on a monitor with a wide range video cassette tape recorder(VCR) or the like.  Since the burst correction signal is arranged, the integration characteristic of the burst signal is corrected and even when disturbance is generated on a monitor, the disturbance is corrected.

Abstract: PURPOSE:To enable to produce the signal pulse output even with distorted input waveform, by cascade connection of flip flop's and giving the input pulse via Schmitt circuit to all the reset terminals. CONSTITUTION:The waveform after passing through the Schmitt circit causes pulse distortion at the leading and trailing.

While this input, the clock pulse C is inputted, and although inversion is sequentially caused from the first stage to the final stage of flip flop, the final stage can not be inverted due to the input pulse R to keep the output of Q  as ''1''. After the last part of the input pulse is inputted, Q  is first reset with the inversion by clock.

Title: Combustion device
Inventor: ITO MASARU
IPC: F23N1/00
Filed: 1986-04-04
Abstract: PURPOSE:To facilitate ignition, by a method wherein a resistor is situated in the middle of a feed air pipe, through which combustion air is guided from a fan in an evaporating cylinder, a connecting tube running from the upper stream side to a constant oil level device is branched, and an air amount regulating means, reducing an amount of combustion air to the evaporating cylinder during ignition, is situated on the downstream side. CONSTITUTION:During ignition, an electromagnetic valve 34 located down a line from a resistor 25 is opened and an escape port 35 is opened, and thereby an amount of combustion air to an evaporating cylinder 17 is decreased. Namely, an amount of air exhausted from a fan 24 during ignition, which is controlled by the resistor 25, is the same as that during constant combustion. As a result, a pressure guided to a constant oil level device 29 and a flow rate of fuel to the evaporating cylinder 17 during ignition are also respectively the same as those during constant combustion. However, since the escape port 35 is opened during ignition, a part of combustion air flows out, and an amount of combustion air to the evaporating cylinder 17 decreases. This constitution decreases the excess air factor of air-fuel premixture produced in the evaporating cylinder 17 during ignition, and facilitates ignition.

Inventor: TSUBOUCHI TAKUMI
IPC: G06F13/28
Filed: 1987-03-31
Abstract: PURPOSE:To take a continuous DMA (direct memory access) address even in case of data transfer beyond the page limit by using a DMA address conversion table to perform DMA independently of a memory management unit. CONSTITUTION:A CPU 11, a main memory 13, and a DMA device 14 are connected through a system bus. A memory management unit (MMU) 12 converts the logical address given by the CPU 11 to a physical address with an incorporated address conversion table when the memory 13 is accessed from the CPU 11. A memory management unit 15 is read/written by the CPU 11 and uses the incorporated DMA address conversion table to convert the address outputted from the device 14 to the physical address and performs DMA independently of the MMU 12. Thus, a continuous DMA address can be taken even in case of data transfer beyond the page limit. Further, the quick memory access of the CPU is possible.

Title: Automatic equiliblium adjusting circuit of metal detection apparatus
Inventor: FUJIMURA TAKESHI
IPC: G01V3/11
Filed: 1995-03-13
Abstract: PURPOSE: To stabilize an operation when a power supply is turned on by a constitution in which an A/D conversion circuit, a programmable gain amplifier and a microcomputer are added to an automatic equilibrium adjusting circuit. CONSTITUTION: By means of a microcomputer 109, digital values according to input digital values from A/D conversion circuits 108a, 108b are normally outputted to programmable gain amplifiers 110a, 110b, and they are fed back negatively in a route from a differential amplifier circuit 5 via an automatic equilibrium adjusting circuit 100 to the circuit 5. As a result, the adjustment of equilibrium advances to a convergent direction, and the balance is adjusted automatically to an equilibrium even when the equilibrium state of a received signal is collapsed. In prior art cases, an adjusting speed is decided by an integrating circuit. In this invention, an adjusting speed can be changed by the program of the microcomputer. The arithmetic operation of the microcomputer 109 is a digital filtering processing operation such as a running average operation or the like. The number of running average operations is small when a power supply is turned on, and the number of running average operations is increased in an ordinary inspection. Thereby, a response speed, i.e., an automatic equilibrium adjusting speed, can be changed freely by the program.
