Title: Multibeam scanner and its light source device
Inventor: HAYASHI YOSHIAKI
IPC: G02B26/10
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To effectively reduce the fluctuation in the pitch of a scanning line caused by an environmental change such as temperature and humidity by setting an adhesive coating area on the peripheral surface part of a coupling lens held by a holder under 1/2 of the entire periphery of the peripheral surface part of the lens. SOLUTION: A coupling lens 2b is stuck and fixed on a holding part 8c2 in which the cross-sectional shape of a holder 8 is an arc, with an adhesive 8e. An adhesive coating area that the peripheral surface part of the lens 2b is coated with the adhesive 8e is set to be under 1/2 of the entire periphery of the peripheral surface part. Then, the lens 2b is held up and down by a jig for holding 10 and its position in an optical axis direction is adjusted with respect to the holding part 8c2 to adjust positional relation between the light emitting part of a light source and the optical axis. In this case, since the adhesive coating area is under 1/2 of the entire periphery of the peripheral surface part of the lens, a situation that the adhesive 8e is stuck to the jig 10 to disturb adjusting operation is prevented even though the lens 2b is held by the jig 10.  When the positional adjustment is completed, the adhesive 8e is irradiated with ultraviolet rays U.V to be cured.

Title: Scanning optical device
Inventor: KAKO RYOSUKE
IPC: G02B26/10
Filed: 1989-09-20
Abstract: PURPOSE:To make the scanning optical device compact and to improve maintenance work by arranging prescribed reflectors so as to pass reflected light through a gap between a scanning means and a lens group. CONSTITUTION:The reflectors 4, 5 are arranged so that reflected light can pass the gap formed between a rotational polygon mirror 1 and lens groups 2, 3, a notched hole 16A is formed on the center part of an optical unit 16 and a photosensitive drum 6 is arranged on the lower part of the center part of the unit 16.

Title: Temporary fixing method of film and device therefor
Inventor: FUJIKAWA NOBORU
IPC: B32B43/00
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality product, in which no wrinkle develops at all in a film at its temporary fixing by a method wherein the tip of the film is temporarily fixed to the tip of a base material after the wrinkles developed in the film are removed by stretching them. SOLUTION: A film 3 is sucked by a vertically movable sucking plate 10 and a vertically movable and pivotable temporary fixing roll 30 positioning on the downstream side in the running direction of the film from the sucking plate 100. By turning that temporary fixing roll 30 to the running direction of the film, the tip of the film 3 is moved along the peripheral surface of the temporary fixing roll 30 to a base material fed to the predetermined position so as to temporarily fix the tip of the film 3 to the tip of the base material 4 under pressing. As a result, even when fine wrinkles develop in the film, the wrinkles can be removed by being stretched on the peripheral surface of the temporary fixing roll.  Thus, at the temporarily fixing of the film to the base material, no wrinkle develops at all and also no bubble is entrapped in the film, resulting in allowing to temporarily fix the film continuously.

IPC: G11B19/02
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a disc apparatus that sufficiently suppresses the generation of damages to discs and has a long service life and high reliability. SOLUTION: A reset signal (h) prohibiting the rotation of a disc-driving motor is supplied to an input-clearing reset priority RS flip flop 20 of a floppy disc apparatus from the computer side when the disc apparatus is turned on. Since the disc-driving motor does not start rotating only by the supply of electricity to the floppy disc apparatus, the rotation is not continued with a data write-read head of the disc apparatus positioned on the same track, so that the disc can serve for a long time.
