Title: Device for holding opened condition of slide door incorporating automatic closing device
Inventor: SEKINE TAKAHARU
IPC: E05F3/22
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a device for holding a slide door incorporating an automatic closing device, in an opened condition, which can hold the door in the opened condition by a force which is always stable even though a coupling end of the automatic closing device with respect to the slide door, and the door itself are vertically biased. SOLUTION: A locking spring member 3 incorporating vertical locking rib 1 which are projected in opposite directions at the opening edges, and formed therein with a locking groove 2 is attached to the slide door opening side end part of a groove 4 in a door header for guiding a slide door, so that locking groove 2 faces the upper end of the rear edge of the slide door. A U-like locking groove 2 formed in the locking spring member 3 has a same cross-sectional shape in the vertical direction, and accordingly, an opening force does never be affected when a holding force and an external force are applied thereto even though members which are engaged with each other by the locking groove 2 are vertically biased.  That is, even though the coupling end 14 and the slide door are vertically biased, a holding action at the opening side end of the slide door, and an external force required for completing an opening condition thereof are held always constant.

Title: Valve unit for regeneration circuit
Inventor: TAKAHASHI KINYA
IPC: F15B11/02
Filed: 1993-04-20
Abstract: PURPOSE:To offer a valve unit for a regeneration circuit capable of corresponding to any kind of an attachment without being removed or fitted. CONSTITUTION:A main valve 12 is provided between the rod side and the bottom side of a hydraulic cylinder 2 and a changeover valve 15 is provided between the rod side and the flow control valve 3. When speed is necessary to be increased, a stop valve 28 is closed. When the hydraulic cylinder 2 rod is extended, a check valve 26 is closed because differential pressure does not yield on a throttle 26s, and the main valve opens by the pressure from the rod side causing pressure oil on the rod side to reflux to the bottom side and increase speed. When load on the hydraulic cylinder 2 increases, a changeover valve 15 is switched, pressure oil on the rod side is discharged to a tank 5 and necessary thrust is obtained. When speed increase is not necessary, the stop valve 28 is opened. When the hydraulic cylinder 2 rod is extended, the main valve 12 does not open and speed increase is not be performed because the check valve 26 opens by the differential pressure of the throttle 26s and pressure oil on the rod side is discharged to the tank 5.

Title: Product dispenser
Inventor: JIAN RUI GERE
IPC: A45D40/02
Filed: 1989-04-14
Abstract: PURPOSE: To obtain a dispenser equipped with an interchangeable reservoir by providing the reservoir with a frustoconical surface that comes to be pressed against a corresponding frustoconical surface of a nut or a support or both of them when integrally joining the reservoir to the support and tightening each sector of the nut around a threaded rod. CONSTITUTION: When a support 7 is further pushed forward in the cylindrical portion 1b so as to fit this, thread of a rod 5 pushes to widen two half-nuts separated by a slit 10 because these two half-nuts are not mutually restricted. The rod 5 slides in a nut 9 accompanied by friction until the nut 9 returns to the position where the refraction completely finishes within the support 7. And a plunger 4 pushes a flat portion 12 of the nut 9. It pushes the frustoconical surface 1c when reaching this position, and makes the two half-nuts no longer being capable of spreading apart by locking them. In this manner, the screw of the hole 11 engages again with the screw of the rod 5, which is thus driven so as to perform translation with respect to the reservoir l when the rod 5 starts rotating with mechanism integrated in the support 7, so that the product 3 can be dispensed.

Title: Formation of carbon coating and device therefor
Inventor: NAKAHIGASHI TAKAHIRO
IPC: C23C16/26
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To optionally control the coating forming rate and the strength and internal stress of carbon coating to be formed by executing coating formation while the degree of vacuum is changed. SOLUTION: The degree of vacuum in a vessel 1 in the process of coating formation is regulated to 0.01 to 1Torr by an evacuating apparatus 6 and is suitably changed so that the prescribed coating forming rate, film hardness and film stress can be obtd. More concretely, the degree of vacuum in the initial stage of the coating formation is regulated to certain value within the range of 1 to 0.6Torr to form an adhering layer with the object S to be coating- formed, and, after that, the degree of vacuum is improved in the ratio of about 0.01Torr/min within the range of 0.5 to 0.01Torr, i.e., the pressure in the coating formation is reduced in this ratio to form a gradient layer on the adhering layer. By changing the degree of vacuum in the process of the coating as the above, the film forming rate can be controlled.  Moreover, since the hardness and inside stress of the carbon film formed simultaneously can be controlled respectively in the thickness directions, even in the case thick film is formed, the carbon film having high hardness and good in adhesion can be formed.
