Title: Head device for magnetic tape
Inventor: OTANI KENJI
IPC: G11B5/10
Filed: 1994-03-31
Abstract: PURPOSE:To improve the running state of a magnetic tape by generating the sliding force toward an edge abutting part against the magnetic tape in accordance with the inclined surface or curved surface on the rise part succeeding to the face abutting part of a fixed azimuth tape guide. CONSTITUTION:At the time of the recording or reproducing operation, a magnetic surface 4a of the magnetic tape 4 is run in the state of pressurized contact with a head chip 2, the face abutting part 5a of fixed azimuth tape guide 5 and a tapered guide 8.

Title: Cylinder driving method
Inventor: TORII TAKAYOSHI
IPC: F15B11/06
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation width of thrust caused by the fluctuation of original pressure of fluid, stably perform low thrust drive of cylinders and make high thrust drive possible. SOLUTION: The drive method for a cylinder 14 is to supply pressurized fluid to the inside of a pair of chambers 14u and 14d composed of a cylinder tube and a piston, and to increase pressure differential after moving the piston to a scheduled position by force caused by the pressure differential of the pressurized fluid. Since the fluid pressure can be maintained high in the drive of the cylinder 14 at low thrust, the pressurized areas A1 and A2 of the piston can be reduced, and the width of fluctuation of the thrust caused by the fluctuation of original pressure of the fluid can be reduced due to the decrease of the pressurized areas A1 and A2. After moving the piston to a schedule position, high thrust drive is possible.

Filed: 1982-04-15
Abstract: PURPOSE:To enable to reduce the resistance of the diffusion layer as well as to perform a high speed operation of the titled semiconductor device by a method wherein source and drain diffusion layers are formed in slanted shape. CONSTITUTION:An insulating film 15 is thickly and inclinationally formed on the side face of a gate polycrystalline silicon 14. Then, when the high density impurities having the conductivity type reverse to that of a substrate 11 are introduced by performing an ion-implantation method, an ordinary ion implantation is performed on the part 17 where an insulating film 15 is thinly formed at the plane part of the source and drain reion. However, as the introduction of impurities by ion implantation is blocked at the section around the gate polycrystalline silicon 14 where the insulating film 15 is thickly formed, thick impurities are not introduced and the region 16 has gradient in concentration, thereby enabling to form a thin and shallow density ion implanted layer on the region close to the gate electrode and a thicker and deeper ion implanted layer as separating from the gate electrode.

Inventor: TASHIRO HIDEO
IPC: H01S3/108
Filed: 1991-03-27
Abstract: PURPOSE:To realize a Raman laser having he average output by introducing gas carbonate laser light into a Raman cell so as to generate secondary inductive Raman dispersion. CONSTITUTION:Laser light is synchronized with a primary stokes light length. Laser light outgoing therefrom is superposed on the gas carbonate laser light and introduced into a Raman cell. A Raman cell part 5 has a multiplex reflection optical system and a gas cooling mechanism. Heavy hydrogen gas or pure orthoheavy hydrogen gas is used as a Raman medium. The multiplex reflection optical system makes two convex mirrors to face each other for making a laser beam to perform multipath reflection therebetween. Thereby, an effective Raman medium length is increased. Further, at every one time reflection, a laser beam is subjected to focusing and also thereby Raman conversion is promoted. Then, a laser pulse transmitted through this Raman cell part 5 is converted into 16mum light through secondary dispersion process.

Title: Image forming device
Inventor: HARA AISUKE
IPC: G03G15/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent fixing tailing in the fixing and re-electrification scattering on a second surface in the case of forming double-sided images by controlling so that re-electrification bias may not be applied on a re-electrification means from a re- electrification power source in the case of forming the image on one surface of transfer material and then forming the image on the other surface of the transfer material. SOLUTION: In this image forming device 1; the moisture of the transfer material S is evaporated as water vapor when the transfer material S passes a fixing device 7 in the image formation on the first surface in the case of forming the image on both surfaces of the transfer material S. Therefore, in the case of forming the image on the other surface (second surface), the moisture qauntity of the transfer material S is decreased and the water vapor generated from the transfer material S is decreased, so that the fixing tailing hardly occurs. In the case of forming the image on both surface of the transfer material S, a controller 15 controls so that a current may not be applied on a re-electrification needle 19 in the case of forming the image on the first surface of the transfer material S and then forming the image on the other surface (second surface).  Thus, the re-electrification scattering caused in the case of forming the image on the second surface is prevented.
