Title: Method for reducing residual stress in rolled stock
Inventor: SUGAYA KAZUO
IPC: B21B15/00
Filed: 1988-11-08
Abstract: PURPOSE:To reduce residual stresses in the width direction of a rolled stock by bringing a thickness of edge parts of an intermediate stock before rolling to be thinner than that of the central part and rolling the stock in that formation. CONSTITUTION:A thickness of both edge parts 1a of an intermediate stock 1 before rolling is formed to be thinner than that of a central part 1b. The intermediate stock 1 having such a section is rolled by an ordinary rolling mill and a section of a finished stock 2 after rolling is formed to be a rectangular section where edge parts 2a and a central part 2b have the same thickness. By that, rolling is performed under a condition in which a draft at the central part 2b of a finished stock 2 is large and a draft at the edge parts 2a is comparatively small. Residual stresses in the edge parts 2a reverse to plus state, that is, the residual stresses originally being compression change to tension and an absolute value of the residual stresses is markedly reduced. Hence, a stress distributing condition is changed and breakdown of saw teeth caused by sandwiching the teeth by cut faces in cutting is prevented.

Abstract: PROBLEM TO BE SOLVED: To attain the mass production of piezoelectric vibrators by means of an inexpensive machine tool and also to increase the solder-welding surface area for mounting the vibrator on a circuit board to improve the electrical connection reliability by connecting the tips of paired lead terminals to a conductive layer soldered to a print electrode of the circuit board by soldering via an insulating plate. SOLUTION: Every lead terminal 1 of a piezoelectric vibrator is previously cut by means of a tool in the length almost equal to the thickness of arm insulating plate 3, and also a recessing/projecting part 4 is formed at the tip of every terminal 1. The tips of paired terminals 1 are set opposite to the paired holes 2 of the plate 3 and put into the holes 2 respectively with light pressure. The plate 3 is made of an elastic material and temporarily deformed by the pressure to open every projection 6 and to make the tip of terminal 1 pass through. Thus the plate 3 is restored and engaged with the terminal 2 at the part 4.  Under such conditions, an anti-high temperature conductive paste is applied on the surface of the plate 3 at a part where the plate 3 touches the print electrode of a circuit board in the width that secures a short circuit between two conductive lands on the circuit board. Thus a conductive layer 5 is formed.

Title: Protecting method for hydraulic iron pipe during inoperation of pressure regulator
Inventor: KAWAKAMI KAZUMI
IPC: F03B15/18
Filed: 1985-12-17
Abstract: PURPOSE:To prevent an increase of a water pressure through simple constitution, by a method wherein, when a pressure regulator, adapted to prevent increase of a water pressure in a hydraulic iron pipe, is inoperative, a water turbine guide vane is slowly closed, and a small capacity auxiliary pressure regulator separately mounted is actuated. CONSTITUTION:A pressure regulator 5, adapted to prevent increase of a water pressure in a hydraulic iron pipe 1, is mounted to a water turbine casing 2, and is controlled by a hydraulic type controller 6. When a guide vane 3 is opened and closed at a speed, for example, lower than the set value of a dash pot, the pressure regulator 5 is closed. In this constitution, an auxiliary pressure regulator 7 having proper small capacity is attached to the water turbine casing 2. When the pressure regulator 5 is brought into an inoperative state, the guide vane 3 is slowly closed, and the auxiliary pressure regulator 5 is actuated to discharge water. This constitution causes water to be discharged by an amount equivalent to a flow rate which is throttled to a water turbine non-constraint running state, and prevents increase of a water pressure in the hydraulic iron pipe 1. Water is discharged in a tailrace, and a particular channel is not needed.
