Title: Electrode support rotating device of electric discharge machining device
Inventor: MORO TOSHIO
IPC: B23H7/26
Filed: 1981-03-06
Abstract: PURPOSE:To improve mounting accuracy of an electrode, by applying static pressure of fluid to the thin thickness part of an electrode holding sleeve, expanding the thin thicknes part to a direction of the center and supporting the electrode of the above described support rotating device. CONSTITUTION:Oil pressure from an oil pump 92 acts upon a piston 74, if an operating lever 76 is lifted against a spring 84, a fluid pressing piston 62 loses its pressing force to cause pressure of fluid 60 to be almost 0. In this way, an electrode 38 is positioned by positioning pins 36, 42 and mounted. When the oil pressure is removed by a solenoid valve 88, the piston 74 and the operating lever 76 are lowered by the spring 84, and high pressure is applied to the fluid 60 through the fluid pressing piston 62. Thin thickness parts 170, 172 of an electrode holding sleeve 50 are expanded by this fluid pressure to make the displacement to a direction of the center, and an electrode shank 40 is held in an automatically aligning state.

Title: Massaging machine
Inventor: TAKAMA TOSHIKI
IPC: A61H15/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To massage two massaging sites, both feet for example, at a time, by means of a simple structure by mounting a roller having many stimulating protrusions in the center of a driving shaft and mounting a pair of massaging rollers on both outsides of the roller. SOLUTION: When a driving shaft 9 is rotated with a motor 6, a massaging base 23 rotates. However, when an idling portion 25 gets into a loaded condition by the insertion of feet between a pair of idling portions 25 and 26, it retains a non-rotating condition, accompanied by the rolling of a steel ball 24, and the inclination of the sliding face of the steel ball 24 causes the opposite face repeat separation and contact. Therefore, massaged areas such as feet or the like held between them are massaged by a pair of massaging rollers 22a and 22b. At this time, if loads increase, the inside massaging base 23 is withdrawn inward against an elastic body 31. The rotation of the driving shaft 9 makes the roller 16 rotate, and the rotation of stimulating balls 20... massages foot soles or the like.

Title: Variable limiter
Inventor: SAKADO YOSHITOMO
IPC: H03G11/00
Filed: 1980-03-14
Abstract: PURPOSE:To enable to simplify the circuit, when both the functions of a variable limiter and a variable resistive attenuator are required, by using the characteristics between drain and source of a field effect transistor. CONSTITUTION:When the voltage VGS between the gate and source of a P channel FETQ1 is greater than the pinch-off voltage, if the voltage VDS between drain and source is negative, almost no current IDS flows to the drain/source and the potential of the output terminal D is almost equal to the potential at the input terminal C. On the other hand, if VDS is positive, the value is not greater than a value determined with VGS, the potential at the output terminal D is limited to a value or less determined with VGS, and the value can be made greater as VGS is greater. Further, when VGS is a pinch-off voltage or less, FETQ1 operates as a pure resistance at small range of VDS and it can be used as a resistance attenuator with the resistor R1.

Title: Controller for stroboscope of camera
Inventor: YOKONUMA NORIKAZU
IPC: G03B15/05
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To make a built-in stroboscope and an external stroboscope optimally emit light by making the start of the light emission of the built-in stroboscope later than that of the external stroboscope. SOLUTION: Just after starting an image pickup by a CCD, a light emission preparation signal XE is outputted from a controller 11. Then, a light emission start signal X is outputted to the external stroboscope from an external strobescope light emission start circuit 41, so that the external stroboscope starts to emit light. Simultaneously, a built-in stroboscope light emission preparation circuit 40 completes the preparation of the light emission by the built-in stroboscope. When specified time elapses after the signal XE is outputted, a light emission start signal TG is outputted from the controller 11, and the built-in stroboscope starts to emit the light by a trigger circuit 36. Namely, when the signal XE is outputted, the external stroboscope starts to emit the light.  When the specified time elapses after that and the signal TG is outputted, the built-in stroboscope starts to emit the light. Therefore, the external stroboscope emits the light first, and the built-in stroboscope emits the light after the specified time.
