Patent JP-H05302639-A (JP)
Title: Hydraulic damper
Inventor: ASHIBA MASAHIRO
IPC: B60G17/015
Filed: 1992-04-24
Abstract: PURPOSE:To adjust a damping force characteristic on both an expansion side and a contraction side according to vibration of a stroke of a piston rod in a hydraulic damper. CONSTITUTION:A piston 2 is fitted into a cylinder 1. Main oil liquid passages 3, 4 are formed in the piston 2. A bypass passage is constituted of an oil liquid passage 9 and a passage member 8. A guide 15 is disposed in the passage member 8. A shutter 22 is fitted to the guide 15. The shutter 22 is held in the neutral position by springs 29, 30, where the bypass passage can be opened. A chamber 15a inside the guide 15 is communicated with a cylinder chamber 1a by a passage member 17 via an orifice mechanism 24 and an orifice 25a while a chamber 15b is communicated with a cylinder chamber 1b via a communicating path 23a. In the case of large vibration of a stroke of the piston rod 7 flow resistance of the orifice becomes large. Accordingly, displacement of the shutter 22 due to an oil pressure is small, thus opening the bypass passage so as to decrease damping force. In the case of small vibration, resistance of the orifice becomes small. Consequently, displacement of the shutter 22 due to an oil pressure becomes large, thereby closing the bypass passage so as to increase damping force.

Title: Semiconductor memory device
Inventor: KIKUCHI HIDEKAZU
IPC: H01L27/108
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory device by which delays in the control signals for control sensing amplifiers can be suppressed effectively without significantly changing the manufacturing steps actually used. SOLUTION: Dummy bit line pairs DBL and/DBL are disposed between desired bit line pairs in a memory cell array 100. Since the dummy bit line pairs DBL and/DBL have no bearing on normal operations, such as reading out of data stored in the memory cell or the like, there is not need to dispose sensing amplifiers SA in a region X in a sensing amplifier array 110 adjacent to the dummy bit line pairs DBL and /DBL. In this way, a vacant region X is formed in the sensing amplifier array 100. The region X has at least a width W, corresponding to the space between the dummy bit line pairs. A contact part C for electrically connecting between a sensing amplifier controlling signal line SLA and a low-resistance sensing amplifier controlling signal line SLB is formed. That is to say, the region X is used as shutting region of the sensing amplifier control signal line.

Abstract: PURPOSE:To execute a development of a high picture quality by forming a thin layer mainly composed of a toner, by setting a gap between a sleeve and a developer control member, to 1.5-6 times of the particle diameter of a carrier. CONSTITUTION:A gap between a rotatable sleeve 2 and a developer control member 6 is set so as to become 1.5-6 times of an average particle diameter of a carrier 4, and also, to the sleeve 2, a superposed voltage of AC and DC is applied from a developing bias power source 9. At the time of a usual development, the sleeve 2 is brought to a high speed rotation of about 115 rotations, therefore, since a frictional resistance of the magnetically adsorbed carrier 4 and the sleeve 2 is small, and also, the gap of the control member 6 is minute, an outflow of the carrier 4 is obstructed, and in a part B, a high concentration thin layer of only a toner 5 is formed. Therefore, a development of a high picture quality can be executed without stirring a developer.

Filed: 1986-06-06
Abstract: PURPOSE:To easily perform the fine adjustment of tracking correction by providing a driving means, which finely moves a rotating shaft in the axial direction, for the rotating shaft to which a single screw thread is attached. CONSTITUTION:A driving part 30 for tracking correction is not especially required at the time of recording. At the time of reproducing, a tracking correction signal is obtained by a magnetic head 1 and a correction voltage based on this signal is applied to a piezoelectric element 21 of the driving part 30. Thus, the variation of thickness of the piezoelectric element 21 moves a rotating shaft 4 in the axial direction through a thrust bearing 22 to perform tracking correction. Since a spring 12 is provided on the side opposite to the driving part 30 of the rotating shaft 4 through a pivot bearing 10, the force with which the shaft 4 is returned toward the piezoelectric element 21 is always applied, and the shaft 4 is finely moved for tracking correction corresponding to the correction voltage applied to the piezoelectric element 21.

Abstract: PURPOSE:To increase the Q0 of an oscillation multiplier circuit and to facilitate comparatively the adjustment of the coupling degree by applying an output of a transistor oscillation multiplier to an oscillation multiplier circuit comprising a band-pass filter using a dielectric resonator so as to extract a desired multiplied wave. CONSTITUTION:The oscillation multiplier circuit 5 to extract a multiple wave consists of a band-pass filter using a dielectric resonator 5-2. Since Q0 of the circuit 5 has nearly 50-30 times of that of a circuit comprising a microstrip line, the multiplication efficiency is improved with a low loss and the possibility to output various modes is decreased. Further, the degree of coupling is changed easily by moving distances d3, d4 between the dielectric resonator 5-2 and a line 5-1 and between the resonator 5-2 and a line 5-3 toward the arrow through the change of the thickness d5 of a quartz-made spacer 6 arranged under the dielectric resonator 5-2. Finally, a desired filter characteristic is obtained easily to improve the multiplication efficiency.
