Title: Clamp device for optical disc
Inventor: KOKADO HIROSHI
IPC: G11B17/028
Filed: 1982-02-02
Abstract: PURPOSE:To reduce face runout of a disc and the burden on the electric circuit system, of an objective lens driver by using a centrifugal force produced from high speed revolutions, and enhancing the hold of the disc with a turn table and a clamp cup. CONSTITUTION:When a current flows to a motor 2 and a motor shaft starts rotation, a spindle stand 4 also rotates, each weight 19 fitted to the stand 4 via a plate spring 16 receives a centrifugal force and is moved far from the rotation center shaft of the stand 4. A notch taper section 19a of each weight 19 contacts a taper 13a of an opening 13 provided for the clamp cup 12 not contacted at standstill and when the rotation of the stand 4 is further increased, the centrifugal force is enhanced to press the said taper 13a outside. When the taper 13a  is pressed, a force moved to the turn table 8 is exerted or the clamp cut 12 and  a force holding the disc 10 from the upper and lower part is further enhanced at rotation.

Title: Semiconductor detecting circuit
Inventor: KADOTA HIROSHI
IPC: G11C17/00
Filed: 1983-01-31
Abstract: PURPOSE:To obtain a semiconductor detecting circuit which has a high-speed operation and low power consumption with a simple constitution by using a diode structure connecting the gate and the drain of an MOS transistor(TR) as a constant voltage source connected with the source of the MOS transistor for initialization. CONSTITUTION:The reset pulse is impressed to a terminal 6 to reset the potential of a bit line 1. Here the potential is set at VDD-VTP for the line 1 to be reset if the mutual conductance of TRp7 is set at sufficiently large value. While the gate-source voltage difference is kept off by the threshold voltage of the TRp7 in a reset mode as long as the threshold voltage of a TRp2 is set equal to the TRp7. If the mutual conductance ratio of a CMOS reverse amplifying circuit is set large with p channel and small with n channel respectively, the identification potential VR of the reverse amplifying circuit approximates to VDD-VTP. Here if VR=(VDD-VTP)-DELTAV(DELTAV: microvoltage) is satisfied, the read-out time is set as tauRD=C1 or V/Inl. Thus the read-out time tauRD is reduced compared with the conventional value. Here VTP is the threshold voltage of the TRp7 and Inl is the ON current of n1.

Filed: 1990-01-26
Abstract: PURPOSE:To hold the picture quality of a sent or copied original excellent at all times by correcting the shading distortion of an image signal at the time of a read of the original by using a shading distortion signal. CONSTITUTION:An averaging means 2 averages the shading distortion signal, obtained by reading a white reference surface by a photoelectric converting element, at intervals of a specific number of picture elements and write means 3 and 8 write the averaged shading distortion signal in a memory 4 in specific picture element units. A subtracting means 3 calculates the difference between the shading distortion signal of each picture element and the averaged shading distortion signal written in areas of the memory 4 corresponding to the respective picture elements. When it is decided that the difference is less than a specific value, the correction write means consisting of a comparator 5, a constant setter 7, a selector 3, and an address counter 8 writes shading distortion signals obtained from picture elements in their corresponding areas of the memory 4. Consequently, a corrected image signal with shading distortion of high quality is obtained at all times.

Title: Equipment for cutting off steel plate during its movement
Inventor: MARUI TOMOTAKA
IPC: B23D36/00
Filed: 1981-02-05
Abstract: PURPOSE:To accurately cut off a steel plate, by providing an automatic control circuit which measures the distance of movement of the steel plate and compensates the deviation of the cut-off position of the plate on the basis of the difference between the measured value and a set value. CONSTITUTION:A pair of drum-shaped rotary cutters 14 are rotated by a drive means 12 to cut off a steel plate 10 being conveyed at a constant speed V. Errors occur between the starting time and revolution speed of the cutters 14 and values instructed by a control circuit 24, so that the position of the cutting- off would deviate. The control circuit 24 compensates the deviation of the cutting-off position. At that time, the circuit 24 integrates the conveyance speed of the steel plate 10 from the time of detection by a detector 16 until the time of the cutting-off end found out by another detector 18, to measure the distance of movement of the steel plate. The control circuit 24 calculates the deviation of the cut-off position of the steel plate 10 from the difference between the measured value and a set value to control the drive means 12 to compensate the deviation. Therefore, the steel plate 10 is accurately cut off.
