Title: Image forming device
Inventor: OGAWA KATSUTOSHI
IPC: G03G15/16
Filed: 1992-08-06
Abstract: PURPOSE:To obtain a high-quality image without fogging or the staining of the back surface of a material to be transferred by making a distance from a magnetic field generating means to the surface of an image carrier longer than a distance from a magnetic body to the surface of the image carrier. CONSTITUTION:This device is provided with a transfer means 1 obtained by forming a non-magnetic conductive member 1b on the magnetic field generating means 1a, the non-magnetic image carrier 2 obtained by forming a photoconductive film 2b on a non-magnetic conductive base material 2a, and the magnetic body 3 magnetized by the means 1a. The distance from the magnetic body 3 to the surface of the image carrier 2 is made longer than that from the means 1a to the surface of the image carrier 2. Namely, the magnetic body 3 is arranged on the back surface of the image carrier so that the distance to the surface of the image carrier 2 from the body 3 may be shorter than the distance between the surfaces of the means 1a and the image carrier 2 in the case of viewing in a vertical direction to the surface of the image carrier 2. Therefore, mechanical adhesive force to a transfer roller side is negated by magnetic attracting force to the image carrier side, and toner which is not electrified yet is held on the image carrier 2 side by the magnetic force.

Title: Magnetic recording apparatus
Inventor: YONEZAWA SEIJI
IPC: G11B21/10
Filed: 1993-08-25
Abstract: PURPOSE:To achieve high-density recording by performing highly accurate tracking by means of pits of irregular depths provided zigzag via a predetermined distance in a direction of tracks. CONSTITUTION:A magnetic head 1 for magnetically recording/reproducing data on a magnetic disc and a capacity detecting head 2 for electrically detecting a tracking signal are supported by a supporting mechanism 3. A head part of the supporting mechanism 3 is movable in a radial direction of the magnetic disc as shown by an arrow by the action of an actuator. The capacity detecting head 2 is used not only to track the magnetic head 1, but to reproduce ROM data detected by the quantity of electricity if tone data is recorded unevenly on a magnetic recording face. Accordingly, the apparatus is able to detect the tracking signal with a high S/N ratio, and simultaneously record data by the magnetic head and reproduce a ROM by the capacitive head with the use of a single disc.

Filed: 1989-08-17
Abstract: PURPOSE:To synthesize the natural expression of a face image by adding a movement parameter and an expression parameter obtained based on a human instinctive or unconscious action which is not included in the input face image information to this image information. CONSTITUTION:When an expression/movement parameter input device 9 inputs the expression and movement parameters, a structure model deforming device 13 reads the coordinate value of each apex of a cubic structure model of a face, etc., out of a structure model data storage part 1. Then an additional processor 11 reads the combination of expression and movement parameters out of a process action storage part 12 to perform a non-periodical process and outputs the parameter combination to the device 13 and a coordinate converter 14. The device 13 reads the position, the direction and the size of the apex of the structure model corresponding to the type of the relevant expression out of an expression synthesization rule storage part 5 to send these factors to the converter 14. Then the device 13 outputs the coordinate value of the deformed structure model to an image synthesizer 8 after the parallel shift, the rotation, etc. Then the corresponding gradation information is read out of a gradation information storage part 7 for each polygon and outputted to an image display device 10 as a synthetic image. Thus the natural expression is synthesized for the face image.

Title: Method of forming wick of heat pipe
Inventor: NAKAZAWA HARUJI
IPC: F28D15/02
Filed: 1984-10-08
Abstract: PURPOSE:To cause a wick to uniformly hold a working fluid and to facilitate the method of forming the wick by burning and solidifying a cotton-like stainless steel cloth directly on the inner wall of a stainless steel cylinder so as to form the wick. CONSTITUTION:By use of a forming tool shown in the drawing, a cotton-like stainless steel cloth 4 is heated for a predetermined time and held in a vacuum furnace, and is burnt and hardened to form a wick. In this method, the state of the stainless steel cloth 4 formed by a stainless steel cylinder 6 and a quartz glass core 7 can be observed with eyes through the transparent quanty glass core 7, and hence it is possible to discriminate whether the compressed and formed state is good or bad. Further, in the vacuum furnace, the cotton-like stainless steel cloth 4 is held for a predetermined time and is burnt and hardened, and thereafter the quartz glass core 7 and a support 8 can be easily separated from other parts. Accordingly, unlike the conventional method in which a semicylindrical material is molten and welded, the stainless steel cloth is burnt and hardened directly to the inner wall of the cylinder. Hence, the working fluid can be held uniformly and the forming method is carried out easily.
