Filed: 1991-07-16
Abstract: PURPOSE:To convey electronic parts at a high speed without damaging them by increasing the conveying speed of the electronic parts between one end of a pipe equipment to a window and reducing the speed between the window to a terminal end. CONSTITUTION:When the conveying of an electronic part 13 is started, a shutter 1-2, solenoid valves 10 and 24 are all set to open state. In this state, the electronic part 13 inside a tube 2 is strongly sucked by the sucking force created by the first sucking device and the second sucking device and is conveyed at a high speed. An air window connected to a suction cup 21 and provided in a pipe 20-3 of an air window device 20 is a hole smaller than the outer shape of the electronic part 13, so that the electronic part 13 reaching the pipe 20-3 does not pass through the air window and, instead, reaches a backup plate by inertia. In this backup plate and inside a subsequent tube 4-A, the electronic part 13 is carried at a low speed by the first suction device, the sucking force of which is adequately adjusted by a regulator 14.

Title: Optical reproducing device for information signal
Inventor: UENO ICHIRO
IPC: G11B7/14
Filed: 1988-07-15
Abstract: PURPOSE:To prevent crosstalk from being generated by arranging almost the same number of optical fibers as that of apertures of a lens to converge light on the optical fiber at the front plane side of the photoreceiving planes of plural photodetectors, respectively. CONSTITUTION:A polarized beam splitter 4 and a 1/4-wave plate 5 comprise a light isolator, and a convex lens 7 and a cylindrical lens 8 comprise a detecting optical system. And the photodetector PDA is constituted by arranging almost the same number of optical fibers (16-18) as that of apertures of the lens to converge the light on the optical fiber at the front plane side of the photoreceiving plane of each of the plural photodetectors (9-14) in a multiple divided type photodetector PD. Therefore, plural incident light beams to one objective lens 6 are made incident in a state with providing a certain angle against the optical axis of the objective lens 6, and aberration is generated in the light beam, thereby, no light with a large incident angle advances through the optical fiber. In such a way, it is possible to prevent the crosstalk from being generated in the photodetector.

Title: Ball joint
Inventor: NEMOTO AKIRA
IPC: F16C11/06
Filed: 1995-06-20
Abstract: PURPOSE: To restrain increase in operational torque by constituting a bearing support arm of a main body part made of bar material and a housing part formed on its end part in an annular shape, and engaging a bearing convex part with a sink on the inner circumference near a base part continuing to the main body part of the housing part. CONSTITUTION: The spherical head part 4 of a ball stud 2 is inserted into an inner spherical surface 7 from the opening 6 of a bearing 5. The bearing 5 is made of extendable/contractible synthetic resin material, its opening 6 is expanded in its diameter so that the spherical head part 4 may pass it. Then, the housing part 12 of an arm 11 is fittingly attached to the housing attaching part 8 in such a state of the projection 10 of the bearing 5 coinciding with the sink 14 of the arm 11. Since the inner diameter of the housing part 12 is shorter than the outer diameter of the housing attaching part 8, the bearing 5 is tightened by the housing 12, the spherical head part 4 can not be pulled out from the bearing 5 which makes no relative turning motion to the arm 11. Thereby, any increase in operational torque is restrained so that the position of a bearing opening can be regulated.

Title: Disposer for strip-shaped object such as film
Inventor: SATO YOICHI
IPC: B65H20/16
Filed: 1988-07-18
Abstract: PURPOSE:To discharge film as uniform scrap film from an outlet of a disposer by providing a center slitter between clip chains which slits a strip-shaped object and holding the object evenly with clips on both sides. CONSTITUTION:A strip-shaped object, such as film, is fed into a disposer with its edges gripped by clips 2. As a certain period of time elapses after feeding is started, the film 1 splits to become scrap film. Subsequently, as a center slitter 20 located between chains 18 of clips 2 rises, a slit is made in the film 1 that has been scrapped, and the film 1 is conveyed, with its edges gripped evenly and uniformly with the clips on both sides, to the outlet of the disposer for positive discharge. After gripping with the clips 2 at the inlet of the disposer has been done positively and stabilized, the center slitter is returned to its original position, and the film 1 is discharged from the outlet as film that has undergone enlargement.

Title: Head slider and disk device
Inventor: KAMEYAMA MASAKI
IPC: G11B5/41
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To maintain the stable floating characteristic of a head slider and to prevent the occurrence of recording/reproducing damage or head clashing by providing a pad in a part other than the rail surface of a substrate surface and reducing the amount of dust deposited on a rail surface. SOLUTION: Pads 14a to 14d are arranged in positions receiving little influence of a floating characteristic so as to be protruded from a substrate surface 10b outside rail surfaces excluding the rail surfaces 12b and 13b of slider rails 12 and 13. Thus, a space between the left and right pads of the substrate is increased, and a slider 10 is supported with good balance at the time of CSS. Also, since the pads are arranged in the vicinity of the slider rails 12 and 13, the contact of the rail surfaces 12b and 13b with a disk surface is prevented and adsorption is prevented. When a disk 20 is rotated, the slider 10 is caused to followingly float by the air flow of medium rotation direction, and dust G flows from the air inlet terminals of the rails surfaces 12b and 13b to outlet terminals.  At this time, for the slider 10, the air flow is not cut off on the rail surfaces 12b and 13b, and the deposition of dust on the surface is suppressed.

Abstract: PURPOSE:To efficiently mark white lines on the ground by sucking a coating material inside a tank with a pump to inject it from a nozzle of an arm, to easily set the position of a white line by extending/contracting the arm, and to allow the device to be stored in compact size. CONSTITUTION:When white lines are marked on the ground, first, an aqueous white coating material is filled in a tank 21, and an arm 9 is rotated and to be locked at a specified position. While a handle 4 is pushed to move a frame 1 with several wheels 2 and 3, a switch 24 is turned on to flow current to a battery for operating the pump. The coating material in the tank 21 is sucked and passed through a delivery conduit and a tube 30 to be injected from a nozzle 14 to the ground. Since the arm 9 is attached so that it can be extended from or contracted to an arm holder 5, a coating material injecting position can be set freely. Since the arm 9 is rotated freely, it can be folded into compact size when not in use.
