Title: Transfer device for image recorder
Inventor: KAMATA AKIRA
IPC: B41J2/44
Filed: 1993-01-22
Abstract: PURPOSE:To improve the fault of a transferred image by a leakage current through paper or thrust force generated on the paper within the range of an image recorder having a restricted size. CONSTITUTION:In a transferring cycle just after attracting stage, image forming and developing stages are not executed but only the attracting stage is executed, thereby the paper 4 is surely attracted to a transfer film. Then, the transferring cycle is started, and a toner image is transferred to the paper 4. Thus, even though the thrust force acts on the transfer film in the case of attraction, it is softened in the case of transfer, so that the paper 4 is not moved and the excellent transferred image having no positional deviation is obtained. Since the attracting cycle and the transferring cycle are not overlapped even in the case of the paper having the high moisture content, the leakage of a transfer current is prevented even though the paper has a high moisture content. Furthermore, even when a distance between a paper feeding roll 9 at the time of feeding the paper 4 to an attracting position and an opposed roll 8 at a position opposed to an attraction corotron 11 is short the excellent image is obtained.

Abstract: PURPOSE:To raise the recording efficiency by magnetizing a main magnetic pole including its tip, so that a short circuit accident of a terminal can be avoided, by constituting a coil consisting of a conductive layer with a platelike shape perpendicular to a main magnetic pole, and providing a coil terminal on the inclined surface of a substrate. CONSTITUTION:On one main surface 11a of a substrate (example: an Ni-Zn ferrite substrate), a pedestal 12 consisting of a magnetic material is provided projectingly. Also, on the surface 11a, a coil 13 consisting of a conductive layer of Cu, etc. is made to adhere and is placed so as to surround the circumference of the pedestal 12. On the pedestal 12, a main magnetic pole 14 consisting of a magnetic thin film of permalloy, etc. is extended and placed in the direction perpendicular to the surface 11a. Also, a pair of inclined surfacs 15a, 15b adjacent to the surface 11a are formed, and each terminal 13a, 13b of the coil 13 is extended and led out onto these surfaces. Since the coil 13 is constituted with a platelike shape perpendicular to the main magnetic pole 14, a parallel magnetic field can be formed, the main magnetic pole including its tip can be magnetized without generating a local magnetizing saturation in the main magnetic pole 14, and the recording efficiency can be raised. Also, since the coil 13 consists of a conductive layer, mass productin of a head whose characterstic is uniform can be realized.

Title: Die-bonding method for semiconductor element
Inventor: TSUBOTA TAKASHI
IPC: H01L21/52
Filed: 1987-02-12
Abstract: PURPOSE:To prevent the generation of vacancy between a header and a semiconductor element by a method wherein the header is subjected to diebonding only after the metal electrode for semiconductor element diebonding has been caused to melt. CONSTITUTION:An approximately 1.2mum-thick film or a die-bonding electrode material Sn 12 is formed on a semiconductor element 11 by using a resistance heater type vacuum evaporation unit. Next, a header 13 is heated to and kept at approximately 300 deg.C by a heater 14, and nitrogen gas 18, heated to approximately 300 deg.C by a heater 17 in a glass tube 16, is blown upon the semiconductor element 11 sucked by a collet 15. In this process, the Sn 12 on the semiconductor element 11 is melted, with its surface roundish due to surface tension. A process follows wherein diebonding is accomplished of the semiconductor element 11 to the header 13. The temperature of the heater 14 is allowed to lower, for the completion of the die-bonding process for the semiconductor element 11. In this way, a strong die-bond excellent in heat conductance may be obtained.

Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To provide an utility knife capable of resisting force in an axial direction tending to push back a blade into a handle though the blade is easily moved in the handle. SOLUTION: A button 30 is depressed and an actuator 50 and a blade carrier 48 are slid along glideaways 82 and 61 to extend or retract the blade through a front slot. The elastic member 74 on the actuator 50 urges projections 76 on the actuator 50 into engagement with detents provided within the handle. During cutting, in order to resist upward force applied to the blade, a blade guard surrounds at least a part of the front slot. On the other hand, in order to protect the carrier 48 from a damage by the blade, a carrier guard 60 is in contact with a blade tip within the handle. The carrier 48 and the actuator 50 include abutting surfaces for effectively transmitting axial compression forces on the blade from the carrier 48 to the actuator 50 without exerting excessive force on the joint between both of them.
