Filed: 1982-05-15
Abstract: PURPOSE:To suppress a signal transmission delay of a word line to a small value by forming the word line of a line direction conductor and a conductor which is connected to the line direction conductor at every prescribed interval. CONSTITUTION:A word line is wired with both a polysilicon layer 24a which operates also as a gate electrode of a signal transfer transistor 27 and an aluminum layer 24b, and both are connected through suitable contacting hole. Thus, the resistance of the layer 24a is large, but the resistance of the layer 24b is so small as to be ignored. Accordingly, it becomes equivalent to the provision of a line decoder at the position of the contacting hole. In this manner, when the contacting holes are provided at start, middle and end points, the CR time constant of the length of the half of the distance between the contacting holes may be considered, and it accordingly becomes equivalent to that the word line is divided into four, with the result that the CR time constant becomes 1/16.

Title: Turboexpansion device for supercryogenic refrigerating machine
Inventor: WATANABE YUUJIROU
IPC: F25B9/06
Filed: 1989-03-31
Abstract: PURPOSE:To make a turbine shaft rotate smoothly so that it can be rotated at high speed by providing a load-controlling device which comprises a first curb part set inside an expansion chamber and a second curb part fixed integrally with a turbine shaft and designed to curb a load acting thrustwise upon the turbine shaft by a repulsive force from the first curb part. CONSTITUTION:A load-controlling device 5 comprises a first curb part consisting of an electromagnet 52 provided inside an expansion chamber 1d and a second curb part consisting of a bolt 51 of permanent magnet fixed integrally to a turbine shaft 2 and designed to curb a load acting thrustwise upon the turbine shaft by a repulsive force from the electromagnet 52. A flow of supercryogenic actuating gas, passing a volute chamber 1a and expanding as it passes a nozzle 12, reaches the turbine 3 and rotates it as the gas passes into an expansion chamber 1d. Then the turbine shaft 2 is given a thrust toward the expansion chamber, since the pressure in the expansion chamber is lower than the pressure in the bearing chamber 1a. But the turbine shaft also gains a force counteracting the thrust because of repulsion acting against the second curb part 51 from the first curb part 52. Therefore, by neutralizing the thrust given to the turbine shaft by a reactive force from the first curb part 52, the turbine shaft is made to rotate smoothly at a gas-thrust bearing 21 so that the turbine can be rotated at high speed.

Title: Locking mechanism for safe
Inventor: TAGUCHI YASUNORI
IPC: E05G1/02
Filed: 1993-04-09
Abstract: PURPOSE:To prevent an upper door from being left open and to reduce the number of part items by providing a cam mechanism at the side portion of a safe, and permitting cams to rotate as a locking device for an upper door operates, thus preventing rotation of the cams when the upper door is open. CONSTITUTION:When an operator slides an upper door 10 open in the direction of arrow C', a regulating member 55 is pulled by a spring 66 during movement of the upper door 10 and is moved in the direction of arrow C'. The regulating member 55 is stopped where an end portion 67 is located immediately above the upper end portion 62 of a locking member 54, for regulating movement of the locking member 52 in the direction of arrow E. Since the locking member 54 becomes unable to move in the direction of arrow E, a circular cam 53 is kept from rotating in the direction of arrows K-K' by the locking member 54; i.e., when the upper door 10 is open the locking member 54 cannot be moved and the circular cams 53 and 52 cannot be rotated, so a locking mechanism 51 cannot be unlocked. Therefore even when the operator tries to draw out a safe 1 with the upper door 10 left open, the projecting portion 59 of the circular cam 52 is hooked to the diagonal portion 69c of a plate cam 69 and the safe cannot be drawn out any further.
