Title: Damping force adjustment type hydraulic shock absorber
Inventor: MACHIDA HIROMI
IPC: F16F9/46
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To lessen the driving torque of a rotary shutter for a damping force adjustment valve in the clamping force adjustment type hydraulic shock absorber. SOLUTION: A piston 7 is fitted in a cylinder 2, and a cylinder lower chamber 2b is communicated with a reservoir chamber 6 through a base valve 12. A cylinder upper chamber 2a is communicated with the reservoir chamber 6 through a communication path made out of an oil passage 5a, an annular passage 5, an oil passage 22, an oil passage 24, an oil chamber 37, a hydraulic oil passage 38, a guide port 41, a shutter port 42, a shutter 40 inner, a guide 33 inner, an engaging part 26, and of an oil passage 23. One directional oil flow from the cylinder upper chamber 2a side to the reservoir chamber 6 side is formed by check valves 16 and 18 in the communication path at both the sides of the extension and contraction of a piston rod 8, and the passage area of the communication path is changed by the rotation of the shutter 40, so that damping force is thereby adjusted.  Since hydraulic oil flowing in the shutter 40 is lowered in pressure by the shutter port 42, directional force in the axial direction is lessened, so that driving torque can thereby be lessened.

Abstract: PURPOSE:To allow a trunk line to execute continuously a call to plural extensions without interposing an operator by constituting a titled exchange so that an extension number which the operator has dialed continuously in accordance with a request of the trunk line is accumulated successively in a series call extension number memory, and when the extension has ended a call to the trunk line and has been released, a central control device reads out the next extension number to be connected, from said memory, and connects the trunk line and the extension concerned. CONSTITUTION:In case when a trunk line E has desired a series call, an operator dials an extension number '320' of an extension A first, and subsequently, pushes '#', and also dials an extension number '350' of an extension B. These extension numbers '320', '#' and '350' are accumulated successively in a register memory 51 by a central control device 40. The central control device 40 fetches the extension number '320' of the extension A to be connected first, from a series call extension number memory 52, and shifts to a connection control of the trunk line E and the extension A. Subsequently, when a call of the trunk line E and the extension A is ended, and the extension A is released, the control device 40 fetches the extension number '350' of the extension B to be connected in the next time from a '0' block of the memory 52, and shifts to a connection control to the extension B.

Abstract: PURPOSE:To ensure a correct left margin of paper even if paper is cued with a longitudinal shift by a method wherein a carrier is provided with a paper detection means for detecting the presence or absence of paper on a platen, and the paper detection means is connected to a control part. CONSTITUTION:On a carrier 12, a paper sensor 1 serving as a paper detection means is provided in the left part thereof opposedly to a platen 11. As the paper sensor 1, for example, a reflection-type photoelectric sensor is used. A light quantity reflected by the platen 11 in the presence of paper differs that in the absence of paper.

A control part 2 controls the rotation of the platen 11 and the movement of the carrier 12 by controlling the rotation of stepping motors 13, 16 in accordance with a predetermined program and an external command, furthermore controlling the printing action of a print head 10. The control part 2 detects the left end position of paper by the output of the paper sensor 1 and determines a printing start position by referring to the left end position. Therefore, a correct left margin of paper can be ensured even if a longitudinal shift exists at the time of paper cuing.
