IPC: G03G15/20
Filed: 1988-05-20
Abstract: PURPOSE:To prevent the transition and adhesion of toner to a fixing roller and to facilitate satisfactory image fixing by covering the surface of one rotating body with a tube of a thin, heat-shrinking fluororesin film and arranging an elastic layer containing a filling material whereto a cation treatment is applied on the other rotating body. CONSTITUTION:A fixing device consists of a pair of rotating bodies, which are the fixing roller 101 and a pressure roller 2. The surface of the rotating body 101 is covered with the tube of the thin, heat-shrinking fluororesin film 104. The elastic layer part 6 of the rotating body 2 contains the filling material whereto the cation treatment is applied. As a result, it is prevented that an image carrier wind around the pressure roller 2, without providing a separating claw. In addition, the transition and adhesion of the toner to the fixing roller, which causes the image of a line to be blotted, is also prevented, without supplying silicon oil gradually from outside to the fixing roller 101 with a felt pad, or cleaning offset toner with a cleaner. To facilitate the satisfactory image fixing is thereby achieved.

Title: Beam lead type diode
Inventor: KAJIMURA TAKESHI
IPC: H01L21/60
Filed: 1987-05-20
Abstract: PURPOSE:To reduce the floating capacitance of a beam lead, and to improve high-frequency characteristics by forming a Schottky junction section and the beam lead connected to an ohmic contact section and disposed onto a columnar body and shaping an air gap between the beam lead and an insulating film. CONSTITUTION:An insulating film 12 is formed onto a semiconductor section 14, one parts of the insulating film 12 are removed through etching, etc., and a Schottky junction section 11 and an ohmic contact 15 are shaped. Columnar bodies 16 are formed to one parts of the insulating film 12 by a metal, and beam leads 13 are shaped onto the columnar bodies 16. Floating capacitance among the semiconductor section 14 and the beam leads 13 is made largely smaller than that only of the insulating film 12 having large permittivity because air gaps 17 having small permittivity are formed, thus improving high-frequency characteristics. Since the beam leads 13 are joined by a P-N junction section 20 in the P-N junction section 20 and columnar sections 21 shaped by an insulator, a beam lead type diode is applied to not only a Schottky diode but also a P-N junction section diode.

Filed: 1988-05-24
Abstract: PURPOSE:To obtain the low-loss and simple optical fiber mode matching device by subjecting single mode optical fibers of spot sizes different from each other to fusion splicing, then stretching the fiber under heating to form a tapered part around the spliced point. CONSTITUTION:The single mode optical fibers 11, 11 having the spot sizes 2a1, 2a2 respectively are fusion-spliced by the discharge from an electrode 2. The optical fibers 11 and 12 are thereafter stretched to form the tapered part 3 around the spliced point in a part of the fibers 11 and 12 while the part near the splice is heated by a burner 4, etc. The effect of confining an electromagnetic field in the tapered part 3 is weakened as the size of said part is smaller. As a result, the electromagnetic field bleeds to the clad layer and the spot size increases substantially. The low-loss and simple optical fiber mode matching device is thereby obtd.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory which designed to efficiently inject electrons in a floating gate and moreover, to efficiently draw the electrons from the floating gate, and to reduce power consumption. SOLUTION: A floating gate 6 on a tunnel oxide film 5 is divided into an N-type region 61 and a P-type region 62. For this, at the time of writing data, a depletion layer is formed in the region 61, but the depletion layer is not formed in the region 62. Therefore, electrons are efficiently injected in the region 62. On the other hand, at the time of erasing data, the depletion layer is formed in the region 62, but the depletion layer is not formed in the region 61. As the result, a drawing of the electrons from the region 61 can be efficiently performed.

IPC: C21D1/00
Filed: 1986-05-29
Abstract: PURPOSE:To improve the heat treatment accuracy of a metallic material by determining the permissible range of temp. and time parameters for obtaining required mechanical properties as the relation between the target treating temp. and target holding time. CONSTITUTION:The permissible range of the temp. and time parameters for satisfying the mechanical properties required for the central part and surface part of a material to be treated is empirically determined as the relation of the permissible range between the target treating temp. and holding time of the surface. The surface temp. of the material to be treated is measured at the prescribed time intervals and the corresponding treatment time regarded to be the time when the material to be treated is treated at the target temp. is determined from the time intervals and the arithmetic mean temp. of the detected temps. The corresponding treatment time is accumulated and the heat treatment is ended when the total corresponding treatment time attains the value within the target holding time. The influence of the variance inevitably arising in the atmosphere temp. of a furnace is averted by the above-mentioned method, by which the material to be treated is treated at and within the target temp. and holding time.
