Title: Optical head device
Inventor: TATSUNO TORU
IPC: G11B7/09
Filed: 1988-04-25
Abstract: PURPOSE:To reduce the thickness of an optical head device, to evade an adhering phenomenon in a low-temperature environment, and to eliminate the colliding sound of an object lens holding body by using a limiter which is composed basically of a fluorocarbon resin mixed with a filler. CONSTITUTION:The limiter 13 has an annular shape and is composed basically of a tetrafluoroethylene resin mixed with fillers, such as glass fibers, graphite, carbon fibers, bronze, molybdenum dioxide, etc., so as to improve the mechanical strength and wear resisting property. If the object lens holding body 1 is light in weight and its colliding force is not strong, another kind of fluorocarbon resin can be used for the limiter. Especially, even when a hot-melt type fluorocarbon resin ETFE, etc., is used, the stability of the dimensions can be improved by mixing fillers. Since such constitution is excellent in chemical resistance, wear resistance, low-compression deforming property, and self- lubricating property, this optical head device can be reduced in thickness and no adhering phenomenon occurs in a low-temperature environment. In addition, the eliminating effect of the colliding sound of the object lens holding body is high.

Title: Method for detecting electric discharge machining condition by ultrasonic wave
IPC: B23H1/02
Filed: 1992-03-30
Abstract: PURPOSE:To easily detect an abnormal discharge condition or an unstable discharge condition by measuring and detecting various behavior in regard to an electrode and a work in electric discharge machining. CONSTITUTION:When electric discharge machining is carried out while a discharge electrode 1 is separably brought in contact (jumping) with a work 2 properly and timely, ultra sonic waves are irradiated on an electric discharge machining area via the discharge electrode 1 or the work 2, so that propagating time for the ultrasonic waves to be propagated to respective boundary surfaces in the light path is measured by means of ultrasonic wave receiving signals 7. By this constitution, measurement is made of the dimension of the work 2 which is being machined, a gap between the electrode 1 and the work 2, a consumption of the electrode 1, and of the volume of stock removed from the work 2 by machining. This constitution thereby enables machined dimension to be enhanced in accuracy, and concurrently enables an abnormal discharge condition and an unstable discharge condition to be detected with ease.

Title: Stand assisting chair
Inventor: TAKEYASU YOSHIHIRO
IPC: A47C7/56
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To assist a user to stand up from/sit down on a chair, by moving the upper end of a gas spring autonomously to the front end part of a rail and, next, being drawn by a drawing spring to the rear end of the rail to push the seat face further upward. SOLUTION: The lower end of a gas spring 6 is rotatably connected with the lower part of a chair frame, and a roller on the upper end of the gas spring 6 slides in a rail 5 and usually has reactive force to push the rail 5 upward in a contracting condition. A drawing spring 7 draws the gas spring 6 rearward by stronger force during extending the gas spring 6 and weaker force during contracting. When the body weight load to stop the gas spring 6 to the front end of the rail 5 is eliminated by leaving of a seater from a seat face 1, the seat face 1 and arms 2, 3, 4 are further pushed upward by the force of the drawing spring 7 and the gas spring is drawn backward.  When the gas spring has force slightly larger than the force corresponding to the body weight of the seater, the seater can easily stand up from the chair, and moderately sit down on the chair since the force of the gas spring 6 acts to support the body weight.
