Title: Screw holder
Inventor: OZAWA FUMIO
IPC: F16B41/00
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To facilitate fitting and removal of a screw at a narrow space where apparatus and machines hesitating magnetic force are installed by using a screw holder with the screw attached onto the claw of a body which is fixed with fixing screws by inserting a screwdriver in the screw holder. SOLUTION: A non-slip grip 2 is provided for a body slide part 1 having a claw at a hollow shaft. An O-ring fixing guide 4, an O-ring 5, O-ring retainer 6, and a fixing male screw 7 are fitted on a fixing female screw 3 having a slide shaft. For its use, a screwdriver is inserted to tighten it with the fixing female screw. By tightening, the O-ring 5 is pushed and fixed on the screwdriver. At this time, it is fixed so that the position of the claw of the body 1 may engage with the head of the screw, and the screw is fitted on the claw. The claw becomes spring-shaped, therefore, the screw is fixed. When the screw is screwed in and advances to some degree, a grip 2 is pulled to this die. With the claw disengaged from the screw, the screw holder can be also used when the screw tightened to the end is removed.

Abstract: PURPOSE:To perform calibration automatically even with high concentration even when the calibration is performed with low concentration by varying the attenuation degree of an attenuator which attenuates the output of the operational amplifier of an oxygen sensor and varying the output of the attenuator automatically. CONSTITUTION:The output of the oxygen sensor 1 is changed by a resistor 11 into a voltage value, which is multified by the operational amplifier 2 and then the output voltage is divided by the attenuator 12 consisting of a resistor 3 and a resistor group 4. Its output is compared by a comparator 7 with a reference voltage 9 and when the output decreases below the reference voltage 9, a signal indicating a decrease in oxygen concentration is sent to an alarm circuit 10 to perform an alarming display. The output of the attenuator 12 is inputted to a comparator 6 and compared with a reference voltage 8 and when the output is larger, the counted value of the binary counter of a switch control circuit 5 is advanced so as to decrease the amplification degree of the operational amplifier 2 to open and close switches S1-S6 of the resistor group 4 which decreases the degree of attenuation properly.

Title: Write protection circuit for power failure
Inventor: IWAMOTO AKIRA
IPC: G06F12/16
Filed: 1978-04-24
Abstract: PURPOSE: To prevent a system from stopping operating unnecessarily even if a power failure occurs during write operation, by avoiding error occurrence at the  time of reading.  
     CONSTITUTION: Power-failure detection circuit 1 detects a power failure, if occurring to an AC power supply while write data are being written from a memory to a write method, and data control circuit 2 mades write data after the power failure into a specific pattern and the write them to the write method. After the write data made into the specific pattern are transferred to the end part of a sector, stop circuit 5 stops the write operation forcibly. As a result, when the write data are read out after the power supply recovers, data for one sector, even if incorrect, are not  regarded as an error because of no absence of data during the write operation.

Title: Clock signal distribution system
Inventor: GOTO HIDEKAZU
IPC: G06F1/10
Filed: 1995-02-14
Abstract: PURPOSE: To supply an in-phase clock signal as a standing wave by constituting the clock signal distribution system by using an electromagnetic transmission line, an amplifying element, and a means which advances the phase of a periodic clock signal, and correcting the transmission phase lag and amplification phase lag of the clock signal. CONSTITUTION: Electromagnetic wave transmission lines SL and SL1 transmit the clock and have open ends as their far ends. This system is provided with an amplifying circuit A equipped with a phase advancing means and a flip-flop F which is supplied with the clock. The clock transmitted through the electromagnetic wave transmission lines SL and SL1 is a sine wave and propagated as a standing wave through the transmission lines SL and SL1. For example, the phase advancing circuit and amplifying circuit are constituted by combining a capacitor C and a resistor R. Then the phase lag of the amplifier is compensated by this phase advancing circuit. When the sine wave is amplified, the level of the input to the amplifier need not be equal to the level of the output, so capacitive coupling can optionally be used for a connection between stages.
