Title: Transversal waveform equalizer
Inventor: TOKIMASA SATORU
IPC: H03H15/00
Filed: 1979-01-16
Abstract: PURPOSE:To constitute an equalizing unit cheaply by performing adjustment with shapes of variable waveforms common to respective taps when the transversal waveform equalizer is constituted by the IF band. CONSTITUTION:A transversal equalizer is constituted by delay circuit 41, gain adjustment circuit 42, branch circuit 43 and synthesizer 47, and phase rotation in echo signal path 45 is equal to every tap, and the phase relation of the input part of synthesizer 47 is held. Consequently, since phase equalization of 180 deg.Xn (n is an integer) is facilitated with the IF band carrier frequency while securing a prescribed delay quantity at every tap interval of the transversal waveform equalizer of the IF band, the equalizer can be adjusted with a uniform variable form by using wideband waveforms such as test pulses and converting them to the base band to detect waveform distortion.

Title: Digital-to-analog converter
Inventor: SHIRAISHI HIDEKI
IPC: H03M1/70
Filed: 1981-01-16
Abstract: PURPOSE:To set an optional voltage variable range, by connecting two operational amplifiers across a load. CONSTITUTION:When the digital input to be applied to weight resistances R1- Rn is 0, the initial voltage to be supplied to a load RL is set by a semifixed resistance VR2. In this case, the voltage to be supplied to the load RL has virtually no change although a semifixed resistance VR1 is actuated. Then the digital input of a D/A converter is set maximum to set the voltage of point B at a certain level except for 0. Thus an operational amplifier OP1 functions as a noninverse amplifier. Accordingly the output voltage of the amplifier OP1 varies by the control of the resistance VR1 to set the maximum voltage. When the digital input is set again at 0, the voltage of the point B is also set at 0 again. Thus the change of the resistance VR1 does not emerge at the output. As a result, both the initial voltage and the maximum voltage can be set simply by controlling once the resistances VR1 and VR2.

Title: Sputtering device
Inventor: CHIBA TAKASHI
IPC: C23C14/56
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To correctly measure the residual amt. of a target with a simple structure, in a magnetron type continous sputtering device, by forming pares 20 for discriminating the consuming degree on the face side opposite to a magnet in the target. SOLUTION: In a vacuum chamber, a backing plate having a function as a cathode electrode connected to a power source, a target placed thereon and a magnet arranged oppositely to the target below the backing plate are disposed, and sputtering is executed to a supporting body. In this device, on the 21b side of the opposite face to the magnet which is the back face of the target 21, pores 20 discriminating its consuming degree are plurally formed. Thus, the consumption (erosion) of the target progresses, and, in the case the pores 20 appear, the sputtering is stopped. As the result, the situation that the target partially penetrates from the surface to the back face can effectively be prevented.

Title: Magneto-optical recording medium
Inventor: MIYAMOTO ISAO
IPC: H01F10/13
Filed: 1989-01-10
Abstract: PURPOSE:To realize high-speed and high-density recording by forming a recording layer consisting of a specific amorphous magnetic alloy film with easily magnetizable axis perpendicular to the film surface. CONSTITUTION:The recording layer consists of the amorphous magnetic alloy film expressed by formula I having the easily magnetizable axis perpendicular to the film surface. In the formula, X, Y, Z, A satisfy 0.001<X<1.00, 0.01<=Y<=0.50, Z>Z0 (wherein Z0 is a compensation composition of rare earth metal at room temp.), and 0.001<=A<=0.20. If the magnetic film is rich in rare earth metal, the coercive force Hc - temp. curve declines drastically near the Curie temp. Tc compared to a magnetic film rich in transition metal. Thereby, recording bits have sharp forms with small bit length. When recording is performed by magnetic field modulation method which enables overwrite, bits with short tails and less irregular shape can be obtained. By this method, the rotation speed of the disk and recording frequency can be increased as well as high density recording can be performed.

Title: Video reproduction speed converter
Inventor: KURODA KAZUO
IPC: G09G5/39
Filed: 1992-01-13
Abstract: PURPOSE:To prevent undesired deterioration in display quality of a display pattern by implementing data transfer in a memory in response to an outrun detection signal. CONSTITUTION:When an outrun detection signal S1 is not received and no outrun processing inhibit signal Sd is outputted from an outrun processing inhibit section 4, an outrun processing section 6 transfers preceding 1st video data V1 written in a 1st area of a memory 2 to a 2nd area. In parallel with the write of succeeding data V1 to the 1st area, 2nd video data V2 are read again from the 2nd area to insert a same pattern. When a signal S2 is outputted but the signal Sd is not outputted, the write of the 2nd video data V2 to the memory 2 is inhibited to interleave the pattern. Moreover, when the signal Sd is outputted, no processing is implemented. Thus, even when an outrun state takes place for a period when no effect is given on the valid display picture of a display section 5, the operation of the outrun processing section 5 is inhibited to prevent undesired deterioration in the display quality of the display pattern.
