Title: Force sensor
Inventor: YASUI RYOJI
IPC: G01L5/16
Filed: 1989-10-27
Abstract: PURPOSE:To accurately measure axial tension and moment by providing the electric circuit means connected to a sensor means and simultaneously measuring the rectilinear component in a vertical direction applied between rigid body like flat plates and the moment component of rotatory power. CONSTITUTION:A sensor means 10 are mounted between two bodies 22, 24 and, when the compression or tensile force (axial force F) vertically applied to the bodies 22, 24 and the moment M applied to a horizontal rotary axis S1-S2 are allowed to act on the sensor means 10, strain outputs are generated in strain gauges 8-1 - 8-4 corresponding to the forces applied to support posts 4-1 - 4-4. When the axial tension F is measured, the outputs of the gauges 8-1 - 8-4 are applied to an operation circuit 16 through a bridge circuit 12 and an amplifier 14 and the sum of the respective outputs is operated. When the moment M is measured, in such a case that the distances from the rotary axis S1-S2 are same, the moment M can be calculated using the differences between the strain outputs V1, V2 and V3, V4 measured by the strain gauges present on both sides by two.

Title: Method for controlling two-cylinder type dehumidifying apparatus
Inventor: HANEDA YASUHISA
IPC: B60T17/00
Filed: 1986-11-21
Abstract: PURPOSE:To prevent the excessive lowering in the internal pressure of the piping from an air compressor to a dehumidifying cylinder, by a method wherein both of dehumidifying cylinders are brought to a regeneration or dehumidifying state when the emitting side pressure of the air compressor lowers to predetermined pressure or a predetermined time is elapsed after the air compressor is stopped. CONSTITUTION:When the continuous operating time of an air compressor CO is below the set time being the dehumidifying limit of dehumidifying cylinders or the air compressor CO transfers from operation to stop, the dehumidification and regeneration of the dehumidifying cylinders DR1, DR2 are not changed over. When the compressor transfers from stop to operation, both cylinders are changed over so as to become opposite to the state of the final period at the time of the previous operation and, at the time of continuous operation, dehumidification and regeneration are changed over at every set time. Further, when the compressor CO stops and a stop time reaches a predetermined time or when the emitting side pressure of the compressor CO lowers to a predetermined pressure, both the dehumidifying cylinders DR1, DR2 are changed over to a dehumidifying state to prevent the further lowering in the pressure within piping, and the delay of the replenishment of dry air to the outlet sides of the dehumidifying cylinders at the time of the next operation is reduced.

Title: Dynamic ram
Inventor: MATANO TATSUYA
IPC: G11C11/407
Filed: 1992-10-19
Abstract: PURPOSE:To increase the operation speed of data lines from a sense amplifier to a current read data amplifier and to reduce the power consumption. CONSTITUTION:When information from memory cells is transmitted to a pair of data lines DL and the inverse DL through a pair of bit lines BL and the inverse of BL by a read circuit, MOS transistors TRs Q1 and Q2 for data line precharge are made conductive by a signal PYS to pull up the potentials of data lines DL and the inverse of DL. When potentials of data lines rise to the precharge level, the signal PYS is cut off to stop precharging. Thereafter, a signal RS is inputted to discharge the electric charge of the data line DL, and the current difference between lines DL and the inverse of DL is detected by a flip flop FF circuit of a current read data amplifier 14. Since precharging is not continued till data output and is controlled by the signal PYS, the current difference which does not bring about the malfunction of the FF is quickly obtained to increase the operation speed, and the power consumption is reduced.

Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To eliminate the nonuniformity in temperature by fixing a heat storage body onto the rear surface of a floor material, and at the same time by allowing a side surface opposite to a side surface where a heat exchange pipe is connected out of the side surfaces of a main pipe to be brought into contact with the heat storage body.
