Title: Camera shutter driving device
Inventor: YOKOYAMA SHINICHI
IPC: G03B9/24
Filed: 1987-11-30
Abstract: PURPOSE:To speed up the opening and closing of a shutter on the high brightness side of a shutter device by employing two sets of opening and closing shutters so as to open and close the shutter by means of bimorphs. CONSTITUTION:1st and 2nd sets of shutter opening and closing devices charging and deforming the bimorphs 1 and 1' are arranged on a shared optical axis close to each other. Prior to the 1st shutter A, the 2nd shutter B is opened, followed by the 1st shutter A. After the 1st shutter begins to open, or when the shutter reaches a prescribed opening, a control means 17 closes the 2nd shutter B with a prescribed delay, and regards the exposing time as a period until the 2nd shutter B is closed since the 1st of the influence of shutter inertia force arising in the opening action. Thus the operation can cope with the high brightness exposure time, and the opening and closing of the shutter devices can be speed up.

Title: Ventilating fan
Inventor: TOMINAGA RYUICHI
IPC: F24F7/013
Filed: 1986-12-19
Abstract: PURPOSE:To prevent flapping of a shutter, by a method wherein auxiliary twist coil springs for opening and closing a shutter are mounted to a plurality of shutter coupling levers and a ventilating fan body, regarding a displacement angle in the free state of the two arm parts of the coll spring, the displacement angle is increased more during opening than during closing. CONSTITUTION:A plurality of open type shutters 5 are coupled together through a coupling lever 6 and simultaneously opened and closed. A twist coil spring 8 for assisting opening and closing of the shutter 5 is located between the cou pling lever 6 and a ventilating fan body 2. An angle produced by the two arm part of the coil spring 8 is longer than 180 deg. under a free state, and is smaller than 180 deg. under a working state. Thus, a displacement angle of twist is increased in the closed position of the shutter 5 than in the opening position thereof. This constitution minimizes an auxiliary force in an opening direction under the closed state of the shutter 5 for stabilization and prevents flapping of the shutter 5 due to wind under a closed state.

Title: Sporting apparatus improved in toughness
Inventor: NAKAI YOSHINAGA
IPC: A63B102/18
Filed: 1988-11-30
Abstract: PURPOSE:To improve the apparatus in its total toughness by means of a channel so as to strengthen the apparatus against external forces, especially impact, by providing a helical channel, the bottom of which is formed by a smooth curved face, on the outer surface of a portion at which relatively high stress may be generated. CONSTITUTION:For example in a baseball bat, a helically-shaped channel 4 is formed which extends from the root portion of a heat 1 to a grip 2. A bottom 5 is formed by a smooth curved face with a predetermined radius (r) of curvature, the size of which is varied in accordance with applications and the kinds of their materials. The form of the bottom 5 of the helical channel 4 is not limited to a circle with a certain radius r of curvature nor, so long as it is a smooth curved face, should be limited to a specific one; a V-shaped channel should be avoided to prevent stress concentration when impact acts thereon. The helical channel is thus formed on the outer surface and the apparatus is improved in its total toughness by the helical channel so as to prevent the apparatus from being broken.

IPC: F16C3/02
Filed: 1994-12-08
Abstract: PURPOSE: To manufacture a spindle excellent in the press-in property to a knuckle arm with good productivity. CONSTITUTION: A round bar 10a is formed into an intermediate worked product 10b by 'header working', and refining by 'thermal treatment', and 'shot' and 'lubricating treatment', as occasion demands, are executed. A screw groove is worked by 'rolling' on a male screw part, and the resulting product is set in a press metal mold to execute the shaft diameter finishing of a bearing installing part and a knuckle press-in part by 'press working'. Since the surface of the knuckle press-in part is made into a drawn surface, the resistance at knuckle press-in is minimized, and the press-in property is improved. Since cutting and grinding are dispensed with, the productivity can be improved.

Filed: 1989-11-25
Abstract: PURPOSE:To allow scrupulous performance by driving and stopping a string oscillation detecting means along the longitudinal direction of a string by a driving means, such as step motor, which operates with the operation of an operating means. CONSTITUTION:The step motor 25 as the driving means drives the string oscillation detecting means 23 along the longitudinal direction while the operating means is kept operated when the operating means is operated.

SOLUTION: After formation of a cover film 2 such as a silicon oxide film or the like on a silicon substrate 1, impurities are introduced into the silicon substrate 1 to form a source and drain regions 31. Next, the cover film 2 is removed by dry etching by chloric gas or the like, and then a selectively grown silicon film 52 high in flatness which does not depend upon the crystal property of the base and does not contain defects is formed preferably in relatively large flow of 5 SCCM or over and at a growth temperature of about 650 deg.C or under on the defective layer 4 existing on the surface of the silicon substrate 1. By going through such a process, even if a high fusing point metal silicide film 7 is made later, a high fusing point metal silicide film high in flatness can be formed.
