Title: Correcting system of memory error
Inventor: MIYOSHI KENTAROU
IPC: G06F11/10
Filed: 1983-08-17
Abstract: PURPOSE:To reduce the overhead of a processor due to memory patrol by controlling a system so that rewriting is executed by an error correction code logical circuit when one bit error is detected in a read cycle. CONSTITUTION:When one bit error is detected in the read cycle, error correction based upon a syndrom signal is executed by the error correction code logical circuit ECC2 and the corrected result is set up in a data register 3. The corrected data are returned to the ECC circuit 2 again to add a check bit to the data dna the check bit-added data are rewritten in a memory 1 by a memory write pulse. If one bit error is detected in the read cycle in case of writing operation, the data corrected by the ECC circuit 2 are set up in the register 3 and the system is controlled so that a partial writing is executed by the data set up in the register 3 and write data. Said control makes it possible to include an ordinary memory patrol function and reduce the overhead of the processor due to the memory patrol.

Title: Eccentric brake type vibration damping device
Inventor: IMAZU ICHIROU
IPC: F16F7/10
Filed: 1982-08-31
Abstract: PURPOSE:To obtain large damping force by a simple constitution wherein a revolving inertial body is made eccentric in high acceleration vibration, resulting in frictionally engaging the outer periphery of the inertial body with the inner periphery of a tubular case in the vibration damping device of apparatuses in piping system or the like. CONSTITUTION:A ball and nut member 3 is eccentrically screwed onto a screw rod 2. The ball and nut member 3 and an inertial body 4 are coupled with each other elastically in the direction of rotation. In low acceleration vibration, the inertial body 4 rotates in following up with the ball and nut member 3. In contrast to this, in high acceleration vibration, the inertial body 4 can not follow up to the abrupt pivoting of the ball and nut member 3, resulting in compressing a spring 6 and causing relative pivoting between the inertial body 4 and the ball and nut member 3. At this time, because the ball and nut member 3 is eccentric to the screw rod 2, the inertial body 4 is pushed radially outwards, resulting in frictionally engaging the outer periphery of the inertial body 4 with the inner peripheral surface of the case 1.

CONSTITUTION:A power source switch 1 is turned on, a voltage of a power supply battery 2 is boosted by a DC/DC converter 7, and a first capacitor 11 with small capacitance is charged. After its capacitor 11 has reached a prescribed voltage, this voltage is inputted and charged to a second capacitor 22 with large capacitance. Also, an LED 4 of an auxiliary light emitting means is allowed to emit a light beam in a photographing preparation stage by using in common the first and the second capacitors 11, 22, and the power supply battery 2. Subsequently, when an auxiliary light emission instructing signal from a controlling circuit 35 of a camera is inputted to a controlling circuit 34, a signal is outputted from a terminal A and the LED 4 is allowed to emit a light beam, and simultaneously, charging to the second capacitor 22 is inhibited forcibly. Accordingly, since the auxiliary light emitting means is allowed to take precedence over charging of the second capacitor, it is possible to cope exactly with a quick photographing property.
