Title: Method for erasing information in magneto-optical recording
Inventor: KIRINO FUMIYOSHI
IPC: G11B11/10
Filed: 1992-06-18
Abstract: PURPOSE:To suppress the deterioration of the output of regenerative signal due to the repetition of recording/erasing by intermittentely irradiating a magneto-optical recording medium with a laser beam for erasing. CONSTITUTION:Silicon nitride layer 2, magneto-optical recording film 3, silicon nitride film 4, metallic film (Ni film) 5 and metallic film (Al film) 6 are formed on a substrate 1 having rugged guide grooves. After recording information on the formed magneto-optical disk by a laser beam, the recorded information is erased by intermittentely irradiating the magneto-optical disk with laser beam pulses. When the laser power for erasing is projected in a pulselike form thereon, effective energy imparted to the recording film 3 is reduced, so the erasing is executed without generating a structural relaxation of the recording film 3. Consequently, rewriting characteristic of the disk is improved.

Title: Control circuit of hydraulic shovel
Inventor: TSUKAMOTO HIROYUKI
IPC: E02F3/43
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To increase the operational efficiency and improve the operability, by connecting the driving oil passage for the boom to the driving oil passage for the arm and providing a changeover valve in the connection oil passage. SOLUTION: In an operation like start of floor excavation, operation of the arm and the rising operation of the boom are simultaneously carried out. In this time, respective pilot hydraulic pressures of the arm remote controller 33 and the boom remote controller 32 are made almost equal to each other. As a result, as a spring 31C force acts on the changeover valve 31, a disconnection condition is kept. In this condition, the hydraulic oil from the second hydraulic pump 11 is all supplied to the cylinder 19 for the boom through the changeover valve 31 and hence, the boom is raised well.  In the middle stage of the operation, since the rising speed of the boom is reduced, the rising operation of the boom starts returning and the pilot hydraulic pressure of the remote controller 32 decreases and further, the changeover valve 31 starts to transfer from the opened state to the closed state. In this way, the hydraulic oil of the pump 11 starts partly flowing to the changeover valve 3 for the arm and the arm speed increases and the operation efficiency increases and further the gain of the boom decreases. Hence, the unsteady state of the boom is eliminated and the operability is improved.

Title: Malfunction preventing device for microcomputer for automobile
Inventor: TOMIZAWA NAOMI
IPC: G05B9/02
Filed: 1987-06-29
Abstract: PURPOSE:To set the time of system-down to the minimum required, by delaying a crystal oscillation stable waiting time only when a clock has disappeared, and releasing a reset state, at the time of releasing the CPU reset state caused by an instantaneous drop of a CPU operation power supply voltage. CONSTITUTION:A clock disappearance detecting circuit 6 monitors a clock signal of a CPU 1. When the clock signal is being generated normally, an integral output voltage of an integration circuit 7 is high, and an output of a comparing circuit 8 is not varied, therefore, changeover switches 4, 5 are held at an (a) position. Accordingly, in this case, when a CPU operation power supply voltage VCC is recovered to a prescribed deciding level voltage V1 and an output of a comparing circuit 3 is inverted to an H level, it is sent as it is to the CPU 1, as a reset release signal, and a reset state is released. In such a way, the time of system-down is minimized.

Abstract: PURPOSE:To obtain a picture satisfying the resolution of a character section and the gradation of a picture section simultaneously by referencing not only the characteristic information of a noted picture element of the local area but also the identification result of the peripheral picture element so as to discriminate the kind of the picture. CONSTITUTION:A peripheral picture element characteristic information calculation circuit 26 calculates the information weighting a peripheral picture element with a coefficient decided in response to the distance from a noticed picture element as the characteristic information of the peripheral picture element and sets dynamically a discrimination threshold level Thb in response to the characteristic information of the peripheral picture element. A normalized maximum density difference resulting from the maximum density difference obtained by subtracting the maximum density and the minimum density calculated by a maximum value minimum value calculation circuit 21 with a subtractor 22 divided by a mean density obtained from a mean value calculation circuit 23 based on the discrimination threshold level Thb is discriminated as the characteristic information of the noted picture element. Then the kind of the picture of the noted picture element is discriminated to decide a threshold level Th binarizing the picture information of the noted picture is decided based on the result of discrimination to binarize the picture information. Thus, both the resolution of the character section and the gradation of the picture section are simultaneously satisfied.

Title: Television signal processor
Inventor: OGAWA YOSHIHIKO
IPC: H04N9/66
Filed: 1994-07-12
Abstract: PURPOSE:To prevent disturbance of a picture due to a clock skew in a video signal by delaying the signal whose extent of delay exceeds a prescribed value by decoding processing so that this signal is about an integral multiple of the field period of an input television signal. CONSTITUTION:Y (luminance) and I and Q (demodulated signals of a color C signal) signals outputted from a letter box decoder 15 are inputted to switches 24 to 26 through delay circuits 54 to 56. Delay circuits 54 to 56 delay the Y, I, and Q signals from the decoder 15 so that differences in extent of delay between these Y, I, and Q signals and Y, I, and Q signals from a sequential scanning conversion circuits 20, 22, and 23 are about integral multiplies of the field period (about one field period). Therefore, a clock skew doesn't exist in the video signal part or the television signal subjected to decoding processing even if a clock skew exists in the vertical synchronizing signal part. Consequently, the disturbance of the picture due to a clock skew in the video signal is prevented.
