Title: Compressed spring device
Inventor: IHARA YASUSHI
IPC: F16F3/04
Filed: 1980-06-27
Abstract: PURPOSE:To improve the degree of weight balance of a rocker arm, by using a plurality of compressed springs and by gradually reducing the constant of the springs according as the deflection increases. CONSTITUTION:A compressed spring device C1 is provided with a first spring 15 of a constant K1, a second spring 16 of a constant K2 and a third spring 19 of a small constant. When a rocker arm 3 is in a swung position of 40 deg., the elastic forces of the springs 15, 16 are equalized to each other and set almost equal to clockwise torque based on the weight of the arm 3. Within the swing range of the arm 3 from its horizontal position to 40 deg., the springs 15, 16 act as a series-connected spring whose constant is smaller than that K2 and the counter-clockwise torque of the arm 3 is shown by a line B1. Within the swing range of the arm 3 from 40 deg. to 90 deg., only the spring 16 acts and the torque of the arm 3 is shown by a line B2. Within the swing range of the arm 3 over 90 deg., the torque of the arm 3 based on the spring 19 can be neglected. Since the differences between the lines B1, B2, A1, A2 are reduced, the degree of weight balance of the arm 3 is improved.

Filed: 1990-04-03
Abstract: PURPOSE: To obtain a highly reliable solid chemical sensor in which drift is suppressed by providing an intermediate layer for establishing an equilibrium reaction in a polymer ion photosensitive membrane and/or a solid between them. CONSTITUTION: As a solid for forming an ion sensitive membrane, a silver plate 1 is immersed into a hydrochloric acid and a silver chloride layer 2 is formed on the surface of the silver plate 1 through electrolysis using a platinum counter electrode. The silver/silver chloride electrode is then sealed with epoxy resin 5 except a detecting part 3 and a take-out electrode 4. Subsequently, agar of KCl solution is injected into the surface of the silver plate 1 at the detecting part 3 and eventually cooled to form a gel intermediate layer 6. A potassium-sensitive membrane 7 composed of polyvinyl chloride, bis, adipate, etc., is formed on the intermediate layer 6. Consequently, the potential on the interface of the solid/intermediate layer and the intermediate layer/ion sensitive membrane is stabilized electrochemically resulting in a highly accurate analysis.

Title: Wire type material protecting apparatus and wire type material protecting apparatus winding device
Inventor: UENO TOSHIYUKI
IPC: B65H75/44
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To reduce an area required for winding even when a wire type material protecting apparatus is wound up and to reduce stress to the wire type material protecting apparatus and to the wire type material. SOLUTION: In a wire type material protecting apparatus 1 constructed by connecting multiple protection tools into a chain shape by means of pins and pin holes, a wire type material (a cable and the like) is stored in the inside. On one side in the pin hole, a hole diameter is increased, so that the pin can be oscillationally moved in the pin hole. Therefore, the wire type material protecting apparatus 1 can be wound spirally on the circumference face of a drum 12. Even when the wire type material protection apparatus 1 is long in length, a winding diameter is not changed though a winding height is increased, so that an area required for winding is small, while stress onto the wire type material can be reduced because of no fluctuation in the winding diameter.
