Title: Printing head in wire dot printer
Inventor: HASHIMOTO TADAO
IPC: B41J2/28
Filed: 1987-06-02
Abstract: PURPOSE:To contrive a high-speed printing and to facilitate a production working, by a method wherein, a plurality of movable parts each consisting of an armature and a shaft body are so composed that magnetic circuit members therefor are commonly fixed to a base member made of non-magnetic material through fitting mechanisms. CONSTITUTION:A plurality of movable parts each consisting of an armature 30 and a shaft body 29 are so constructed that magnetic circuit members 24 therefor are securely held to a housing 13 of a non-magnetic material through fitting mechanisms 37. In this manner, the center of gravity of the movable part can be made to just or nearly coincide with the shaft body 29, which results in the decrease of the moment of inertia of the movable part to the shaft body 29 causing the enhancement of a printing speed. Additionally, all the two or more magnetic circuit members 24 are insulated from each other by the housing 13 of a non-magnetic body, thus eliminating the magnetic interference and enabling the enhancement of a printing speed. Furthermore, since unit printing mechanisms 36 are preassembled and the magnetic circuit members 24 thereof are fixed to the housing 13 through the fitting mechanisms 37, the production of printing heads can be facilitated.

Title: Optical coupling device
Inventor: IWASHIMA OSAMU
IPC: H01L31/12
Filed: 1985-06-25
Abstract: PURPOSE:To contrive miniaturization of a mold package by a method wherein the light, which becomes the transmission medium of the signal, emitted from a light emitting element is brought to a light receiving element by the scattering effect of the light scattering agent contained in resin without utilizing the reflection generated by the interface of the resin. CONSTITUTION:A light-scattering agent is put in the resin 11 containing a light-emitting element 13 and a light-receiving element 14, and the light-emitting element and the light receiving element are optically coupled by the scattering effect of the light-scattering agent. As a result, even when the interface of the light coupling resin 11 and exterior molding resin 13 is changed, the quantity of light reaching the light-receiving element is unchanged, because the reflection of light on the interface is not utilized. Also, as the device is formed in double structure using the photo-coupling resin and the exterior molding resin, the mold package smaller in size than the conventional triple structure optical coupling device can be manufactured.

IPC: H01L21/00
Filed: 1983-07-29
Abstract: PURPOSE:To improve abrasion resistance, to stabilize suction by a vacuum collet and to enhance the reliability of products by forming the tip section of a pellet push-up needle used for a semiconductor pellet bonding device by diamond. CONSTITUTION:When a plurality of semiconductor pellets 2 aligned on a masking sheet 1 are sucked in succession by a vacuum collet 3, the semiconductor pellets 2 are sucked easily by breaking the masking sheet 1 through by a pellet push-up needle 11. The pellet push-up needle 11 is constituted by bonding diamond 13 with the nose section of a main body 12 formed by carbon steel SK. Accordingly, since abrasion resistance is improved and the nose section of the main body 12 is not flattened, the pellets 12 can be pushed up stably, a mistake on a suction is eliminated, and excellent bonding is attained.

Abstract: PURPOSE: To reduce noises with a forward-current recovery time made long by diffusing a killer to a dummy pellet whrer no PN junction is formed without diffusing the life time killer to a pellet with a PN junction and by connecting it in series to the PN junction pellet.  
     CONSTITUTION: Semiconductor pellets 3 with a PN junction formed are connected in series, and sndwiched between electrodes 2 fitted with lead line 1 to constitute the current unit. At this time, a life-time killer is not diffused to pellet 3 and dummy pellets 4 to which a killer such as Pt and Au has been diffused are fixed to both the side of lamination pellet 3. At this time, dummy pellet 4 when employing a P- type Si pellet gains more effect of prolonging a recovery time in terms of mobility.  As a result, there is no need to insert a seies resistance into the semiconductor  element, no dispersion of characteristics appears because of no killer diffusion of the  PN-junction pellet, and the voltage drop is also reduced.
