Title: Driving method for solid-state image pickup device
Inventor: MATSUDA YUJI
IPC: H04N5/335
Filed: 1985-01-10
Abstract: PURPOSE:To reduce a smear of an element when a signal charge is generated on a photoelectric transducer by impressing a prescribed voltage on a read out gate and transferring a signal charge leaked to a vertical transfer part to a photoelectric converting part. CONSTITUTION:The signal charge that is stored at a photodiode 11 is transferred to a transfer channel 13 by impressing the pulse of one line per one horizontal period on a read-out gate 12 by a read-out shift resister 16. Next, it is transferred toward a vertical direction by a pulse from a transfer shift resister 17 and is transferred to a horizontal CCD14. Although an electric potential of the read-out gate 12 and that of transfer gate 18 are both kept at a low level in a normal state, the electric potential under the read-out gate 12 is kept higher than that of the transfer gate 18 to transfer the leaked signal charge under the transfer gate 18 of the transfer channel 13. After that, the signal charge is read out following a prescribed time and the signal charge under the transfer gate 18 is transferred to the transfer channel 13.

Filed: 1990-01-10
Abstract: PURPOSE:To stabilize the C/N and error rate by forming an oblique vapor deposition film as the surface layer of the head sliding side of a Co-Cr perpendicular magnetization film. CONSTITUTION:For example, polyimide particles of 160Angstrom diameter are dispersed by the distribution of 16 particles/mu<2> on a 10mum thick polyimide film 1 having 20Angstrom  average surface roughness. The film is electrostatically stuck to an endless belt comprising a 100mum thick titanium foil, on which the Co-Cr film is formed by electron beam vapor deposition while the conveyer system is varied in speed to form a continuous structure of the perpendicular magnetization film 2 and oblique vapor deposition part 3. This film is then transferred to another vacuum chamber, where a plasma polymn. film of 100Angstrom  thickness is provided on the film, and a hard carbon film of 120Angstrom  thickness having 2,700 Knoop hardness is formed by sputtering as a type-A protective layer 4 containing 'Fonplin Z-25(R)' by the amt. corresponding to 50Angstrom  thickness. Further, a type-B lubricant layer 5 comprising a mixture of amide stearate by the amt. corresponding to 20Angstrom  thickness and stearyl stearate corresponding to 30Angstrom  thickness is provided on the layer 4. Then a back coating layer of 0.5mu thickness essentially comprising carbon and urethane is provided to constitute the magnetic tape. By this method, the C/N and error rate of the medium can be stabilized at preferable values.

Filed: 1993-01-13
Abstract: PURPOSE:To improve the performance and to quicken the response of the control loop system by setting an optimum dynamic range regardless of the quantity of crosstalk of a reproduced chrominance signal. CONSTITUTION:An input recovery chrominance signal 100 is given to an ACC feedback loop comprising a variable gain amplifier 1, a frequency converter 2, a BPF 3 and a peak detector 4, in which a peak level is made constant in matching with a large level for each 1H to increase the S/N.

Filed: 1979-01-17
Abstract: PURPOSE: To decrease leak of working oil by providing a tip with a flat section around the central hole of a valve seat and contacting this section of the end face of a plug.  
     CONSTITUTION: When a hydraulic booster is not actuated and a power steering device is actuated, the upper hydraulic pressure of the power steering device all rises, that is to say, the pressure of the ports 52 and 53 rise also through the throttle valve of the booster if the relief valve mechanism is actuated. As a result, the pressure of the main valve room 59 rises also. When the pressure of the main valve room 59 exceeds the preset value, the pilot valve 67 is actuated, the flat section at the tip 61c of the valve seat 61 contacts the end face 57a of the plug 57, and a double orifice is formed with the orifice 63. By applying the pressure of the pilot room only the this flat section and controlling the leak of working oil, the response of the power steering device is prevented from being lowered.

Title: Light displacement measuring apparatus
Inventor: TAKAGI JUNICHI
IPC: G01S17/06
Filed: 1986-01-14
Abstract: PURPOSE:To achieve higher resolutions, by a method wherein an interference light electrical signal with its peak value controlled fixed is binary-coded and counts corresponding to the binary coding of a displacement of an object to be measured based on the counting thereof are determined to interpolate a measured value corresponding to the binary coding according to a level of an interference light electrical signal with its peak value controlled fixed. CONSTITUTION:An output of an AGC circuit 71 is converted into a digital value by an A/D conversion circuit 78 to be inputted into a CPU76. An output of a monostable multivibrator 73 corresponds to a peak value of an output signal of the AGC circuit 71 and hence, the measuring accuracy becomes lambda/4. When an output curve rises from a measuring point (displacement value A), a displacement value (a) corresponding to a level V is given by a=(lambda/4).(V/Vo) if this curve can be approximated linearly, wherein Vo is a level difference between peaks. Therefore, a more correct measured value will be A+a. CPU76 performs an interpolating computation to display a displacement value finally obtained on display unit 77.
