Title: Flow throttling device with temperature compensator in hydraulic circuit
Inventor: MIKI NOBUAKI
IPC: F16H45/02
Filed: 1983-09-07
Abstract: PURPOSE:To compensate for changes in the amount of oil flow caused by temperature changes of hydraulic fluid by opening and closing one of two throttles at least placed in parallel using shape-memory alloy valves. CONSTITUTION:A throttle valve 302, equipped with a check valve having a check ball 300A, has a throttle valve 311 which is open all the time, and an auxiliary throttle valve 331 which is formed in parallel with the throttle valve 311. This auxiliary throttle valve 331 is open-close controlled by a shape memory alloy plate valve 312. In other words, when the hydraulic fluid is lower in temperature than its transformation point, it is transformed to open the auxiliary valve 331, and when it is higher, it is restored to its former plate shape to close the auxiliary valve 331, thus the changes in the flow of hydraulic fluid due to temperature changes can be compensated.

Title: Recording and reproducing device
Inventor: SATO HITOSHI
IPC: G11B15/43
Filed: 1990-06-27
Abstract: PURPOSE:To prevent slackening of a tape even when a brake is worked by cutting off a power source during high speed traveling by connecting a load to a reel motor before an output voltage is lowered depending upon a tape traveling state at the time of detecting a power voltage drop. CONSTITUTION:When a power voltage drop is detected, the load 104 is con nected to the reel motor 102 in place of a motor driver 103 before the output voltage of a power source circuit 112 is lowered, but depending upon the tape traveling state. The reel motor 102 or 107 connected with the load 104 or 109 is worked as an electrical brake for a reel which will continue to rotate by inertia. Afterward, when the output voltage of the power source circuit 112 is lowered a brake device is operated. By this method, even when the power voltage is dropped during the high speed traveling of the tape, one reel motor having larger inertia is worked as the brake, and since the brake device in the main body is operated after the rotating speed of the reel is lowered, slackening of the tape is therefore prevented.

Since these layers are thus arranged, the asymmetric property of the operating characteristic is secured, and the half-selection current can be reduced when a matrix is driven.

Also, length adjustment at a work site can be easily performed by cutting only. Because the connecting metallic parts 4 are fixed to the ceiling bars 3 by screwing the screws 9 in the screw-in parts 8, work can be simply executed by using a general-purpose tool.
