Title: Forming method of element for slide fastener and its device
Inventor: FUKUROI TAKEO
IPC: B21D53/50
Filed: 1979-10-29
Abstract: PURPOSE:To form projecting parts at a constant pitch, migrate excess metal and improve element strength by pressure-grasping the projecting parts in the longitudinal direction of the inside surface of the V-shaped legs of a metal straight bar body of a Y shape in section by means of forming rolls. CONSTITUTION:The entire outside circumferential surface and entire inside circumferential surface of a straight bar body 1 of an approximately Y shape in section comprising a metal material are pressure-grasped by means of the forming circumferential surfaces 24, 25, 26, 27 of forming rolls 20, 21, 22, 23 so as to leave no clearances. Parts 18, 19 of the projecting parts 14, 15 of the opposing inside surfaces 12, 13 of a pair of leg parts 10, 11 expanding in the form of V are pressed by means of the forming rolls 20-23. As a result, the straight bar body 1 closely contacts the forming rolls 20-23 and is formed to the shape conforming to the forming cavity. It causes work hardening by the migration of excess metal formed same to the shape of forming space. This blank material 100 is cut with the central position of each projecting part of at least one leg part as a cutting position, whereby it is formed to fastener elements.

Abstract: PURPOSE:To accurately detect a flow rate without receiving the effect of disturbance light by constituting the title apparatus so that a fluid to be measured flows in a vortex chamber and the ball in the vortex chamber is revolved in the vortex chamber by the vortex stream of the fluid to be measured. CONSTITUTION:A vortex case 1 composed of a translucent resin is constituted by integrally forming a vortex chamber 2 having a vertical circular cross-section, the inflow port 3 provided to the outer periphery of said chamber in the tangential direction thereof and the outflow port 4 provided thereto in the direction of the horizontal center axis thereof.

A light emitting element 9 and a photodetector 8 are provided on the outer peripheral side of the case so that the center of an optical axis passes on the revolving track of the ball 5. When the fluid to be measured flows in the vortex chamber 2, the ball 5 is revolved in the vortex chamber 2 by the vortex stream of the fluid to be measured. The number of revolutions of the ball 5 are proportional to the flow rate of the fluid to be measured and, by the blocking of light when the ball 5 is revolved, a stable flow rate signal can be taken out.

IPC: G01N27/416
Filed: 1985-06-25
Abstract: PURPOSE:To make it possible to measure the salinity of sea sand or sea gravel with a reduced measuring error, by using a chloride ion selective electrode. CONSTITUTION:Silver chloride is mixed with a solution of salt adhered to sea sand or sea gravel or an uncured kneaded mixture of sea sand and cement.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a stick-slip and realize a maintenance free by forming a groove whose side wall is slanted for a slide direction, one end is a dead end and other end is released to the side end edge on a slide surface. SOLUTION: Grooves 6d, whose one end is a dead end, slanting for the slide direction are engraved at an equal interval on the slide surface 6a of a slide shoe 6. These grooves 6d are extended in the slant direction facing to both ends alternately while keeping some interval mutually from the center line of the slide direction of the slide surface 6a and its tip is released to the side end edge. As the one end having an angle for the slide direction formes the groove 6d with a dead end, by the telescopic motion of a boom the worn powder generated on the slide part of a third step boom (a second step boom 1b) and the slide shoe 6 is entered to the groove 6d of the slide surface 6a and discharged to the outside through this groove 6 and the condensation of the worn powder can be prevented by the slide surface 6a. Thereby, the stick-slip at the slide part can be prevented.

IPC: B65G17/38
Filed: 1985-06-26
Abstract: PURPOSE:To reduce a degree of wear in a chain so sharply as well as to maintain its exact pitch accuracy, by interlinking a lap part between both internal and external link plates, upon locking one side, with a join pin having an antifriction bearing in a space with the other side. CONSTITUTION:A chain 1 is interlinked by each join pin 6, while inside link plates 2 and 2 are locked to the join pin 6, and outside link plates 3 and 3 are installed by an antifriction bearing.

Title: Recording method
Inventor: ITO YOSHIMASA
IPC: B41J2/015
Filed: 1990-05-30
Abstract: PURPOSE:To enable recording to be performed by discharging ink without using a micro-nozzle by a method wherein ink is replenished in a liquid state to a vibratile filament material so as to stick thereto, a side wave is generated at both ends of the filament material with a vibration driving source, an ink drop is discharged at a position where two side waves overlap each other to be amplified, and a recording medium is recorded on. CONSTITUTION:Since ink A flows down to a lower ink reservoir 3b along a filament material 2 from an upper ink reservoir 3a under a still state of (a), the ink is replenished so that the ink A may stick to an overall length of the filament material 2. Therefore, when a pulse is applied to vibration driving sources 4a, 4b at both ends, the filament material 2 comes to be of a vibration initial state as given in (b), and respective side waves W1, W2 are generated at both ends of the filament material 2 at that time. Then, since two side waves W1, W2 overlap each other at a specific position of the filament material 2 to be amplified in discharge of (c), a large side wave W3 is generated. Therefore, a portion of the ink A becomes an ink reservoir B to be discharged sidewards, which is stuck to recording paper 5 to be recorded.
