Title: Microprocessor containing redundant register
Inventor: SATO YUJI
IPC: G06F11/16
Filed: 1990-04-27
Abstract: PURPOSE:To improve the yield of an integrated circuit by providing a redundant register, a storage means which stores a specific register having a trouble, and a switch means. CONSTITUTION:One or more stand-by registers Rs are provided to (n) pieces of registers R0 - R3 included in a microprocessor 501. The storage means 160 - 163 store the troubles if detected in those registers R0 - R3. Then a switch means 505 has the accesses to the registers Rs according to the means 160 - 163 when the accesses are applied to the register R0 - R3. Thus the access given to the faulty one of registers R0 - R3 is switched to the access given to the register Rs. As a result, the manufacturing defects can be evaded to the registers and the yields of these registers are improved.

Title: Dynamic ram and testing thereof
Inventor: SATO KATSUYUKI
IPC: G11C11/404
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To prevent flow of a DC current between both MOSFETs by supplying, to the gates of both MOSFETs, a common divided voltage through the level shift with the diode type MOSFET of the same conductivity type having the threshold voltage which is higher than the threshold value in the absolute voltage of the respective output MOSFETs. SOLUTION: The threshold voltage Vthn1 of MOSFET Q53 is set in the absolute value to smaller than the threshold voltage Vthn2 of corresponding output MOSFET Q56 and the threshold voltage Vthp1 of MOSFETQ54 is set in the absolute value smaller than the threshold value Vthp2 of the corresponding output MOSFET Q57. Under this condition, MOSFETQ56 turns off because only the threshold voltage Vthn1 of MOSFETQ53 which is smaller than the threshold voltage Vthn2 is applied across the gate and source. The output MOSFETQ57 also turns off. As a result both output MOSFETs Q56, Q57 are also turned off.

Title: Preamplifier
Inventor: KATO MINORU
IPC: H04N5/335
Filed: 1986-05-16
Abstract: PURPOSE:To suppress the occurrence of noise and to improve the sensitivity of a video Camera by temporarily storing signal charges in the input capacitor of the titled amplifier, reading them by an amplifier of open loop, and resetting it instantaneously by an amplifier of closed loop at the time of resetting an input voltage. CONSTITUTION:The signal charges are outputted from a photoelectric conversion circuit 8 in synchronism with pulses HP. When a pulse RP is in a low level, the pulse HP is in a high level, and the signal charges Q are outputted by the circuit 8 and stored in a capacitor 3. The output voltage of an amplifier 4 is feedbacked through a feedback resistor 5. The larger the amount of the feedback comes, the more the said charges are stored in the capacitor 3. Therefore, the resetting of the capacitor is executed dynamically. Dy turning off a MOS transistor 6, the signal charges are read out as a voltage, and the preamplifier operates. At the time of the signal-reading, the amplifier 4 comes to be open looped, and consequently, the noise level is made lower in comparison with a conventional preamplifier.

Title: Method and device for automatic detection of welded part of wheel rim or the like
Inventor: KUWAJIMA HIDEAKI
IPC: G01N21/88
Filed: 1978-09-09
Abstract: PURPOSE:To make it possible to detect a welded part automatically and definitely by making use of a difference in color or reflection coefficient between the welded part and base metal, by projecting light on the circumferential surface of a wheel rim while the welded wheel rim is turned once. CONSTITUTION:Wheel rim 1 is rotated by rim rotating unit 2 at a constant speed and in a constant direction. Light 4 emitted by light projector 3 strikes the circumferential wall of wheel rim 1, where it is reflected to reach photo detection part 5 of light projector 3. At this time, even after the welding of part 6 of wheel rim 1, it is darky in comparison with other wheel base metal parts, so that a scan by projecting light 4 will change the reflected light in color. The change of the reflected light like this is transferred to color-difference or reflection-coefficient difference discriminator 7, where when the change of the reflected light, i.e. welded part 6 is discriminated, a signal is immediately sent out to rim rotation controller 8, thereby stopping the drive of rim rotating unit 2.
