Title: Sodium vapor trap
Inventor: YAMAMOTO HAJIME
IPC: B01D8/00
Filed: 1979-04-23
Abstract: PURPOSE: To conduct an efficient, long-period sodium-trapping operation by installing a means to control the temperature of cover gas entering container to a temperature at which sodium vapor and mist collected with a trapping means is condensed.  
     CONSTITUTION: Cover gas is cooled by a cooler 17 to a given temperature, flowed through gas inlet 11a into container 11, passes through metal net 16, and goes toward gas outlet 11b. At this time, the surface of the metal net 16 traps sodium vapor and mist from the cover gas, and as a result, pressure difference is generated between the inlet and outlet. The pressure difference ΔP is always measured with a differential pressure oscillator 20 in controlling means 19, and when it exceeds the set value ΔPs of the comparator-judgement unit 21, a blower 18 of the cooler 17 is stopped. This causes collected sodium particles to be condensed into liquid and flowed down the metal net 16, which is accumulated into the container 11 bottom and discharged to the outside.

Abstract: PURPOSE:To improve the use efficiency of an FPC (flexible printed circuit) negative by designing it so that it has a shape corresponding to the front of a camera when being bent at 180 deg. along a perpendicular line. CONSTITUTION:When a second part 1b is bent at 180 deg. along bend predeterminate lines (a) and (b) at the time of setting an FPC to the front of the camera, it has a shape corresponding to the shape of the front of the camera. That is, a second part 1b in the right of the bend predeterminate line (b) is bent at 180 deg. toward the front of the surface of paper in the position of the predeterminate line (b) and is matched to a second part 1b in the left of the predeterminate line (b) and is bent at 180 deg. toward the rear of the surface of paper in the position of the predeterminate line (a). Then, a curved edge part 1d of the side edge of the second part 1b faces a curved edge part 1e of the first part 1a, and as the result, the shape of the FPC correspond to the front of the camera and can be attached to the camera front except a barrel part D. Thus, the FPC whose slug due to punching is considerably reduced is offered. Thus, the production cost is reduced and the use efficiency is improved.

Title: Current limiting device
Inventor: ISHIKAWA TOSHIHIRO
IPC: H01H37/76
Filed: 1988-03-04
Abstract: PURPOSE:To enable a device to be automatically released after the working of limiting current, by setting superconducting material having critical current almost equal to interrupting current, between electrodes. CONSTITUTION:When limited current flowing through a circuit exceeds specified limit current and comes to an interrupting current value, then superconducting material 11 exceeds critical current density, and accordingly, a superconducting state is broken, and electrical resistance is suddenly changed to be heightened. In this manner, the superconducting material 11 is changed into an ordinary conduction state from a superconducting state, and then, current limiting action is performed. Besides, change between the superconducting state and the ordinary conduction state is reversible, and so after current flowing through a circuit is limited, if the excess current of short circuit current or the like is gone, the superconducting material 11 is released in the superconducting state, and accordingly, automatic release can be performed.

Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently form fine grooves on a glass disk substrate by press-forming glass with metal molds for forming to form the substrate transferred with the working grooves of the metal molds for forming, then forming a magnetic recording layer on the substrate. SOLUTION: The glass 3 is first packed between the metal molds 1, 2 for forming worked with the fine working grooves on the surfaces and after the glass 3 is softened by heating, the glass 3 is pressed by the metal molds 1, 2. At this time, the working grooves of the metal mold surfaces are transferred to the surface of the glass 3. Since the glass disk substrate has the high hardness of the surface, the fine working of the surface by a cutting method is difficult, but the formation of the glass disk substrate having the fine grooves on the surface is made possible according to this method. Next, the magnetic recording layer is formed directly or via a ground surface layer on the glass disk substrate formed by the method.
