Filed: 1979-02-20
Abstract: PURPOSE: To make efficiency of manufacture higher by a construction wherein the bonding area of semiconductor chip is extended along the lead wire direction in case of wire bonding wherein the wire of chip reaches the bonding area outside this semiconductor device.  
     CONSTITUTION: The bonding area 2E, 2B of semiconductor chip 1 is contrived so that bonding area's longer side may be pointed along the wire 3 as indicated in the drawing. By this construction the areas 2E' 2B' are useless, so they are utilized as the forming area for the other kind of divided element. Thus it is desirable that the converted active areas are increased by lessening the bonding areas by the unit area of divided element in case of the transister in which a device consists of many divided elements. By this method the shortest wiring is achievable and the manufacturing efficiency of wire bonding and moreover increase of active area is achievable.

Abstract: PURPOSE:To obtain an electromagnetic apparatus which is strong against dew- condensation by providing a covering insulation plate which covers outside of an iron core and a coil fitted on the core, is fitted on the core with the coil and insulates between the coil and the core and by adhering the end of the covering insulation plate projected outside between the coil and the core to the side of the coil. CONSTITUTION:A covering insulation plate 18 fitted on a secondary coil 13 covers and insulates up to near the end of the secondary coil 13 and is fixed on the coil 13 by previously winding the end of the plate 18 projected outside of an iron core 11 where there is the corner of the coil 13 with an adhesive tape 19 several times. Dew becomes a water drop by temperature rise due to operation of a transformer 10 and the water drop flows down on the surface of the plate 18 since the plate 18 is adhered closely to the end of the coil 13 when the water drop flows outside of the core 11 down to the surface of the coil 13. For this reason, the water drop does not stay between the coil 13 and the plate 18 and the interlayer short-circuit of the secondary coil 13 can be prevented.

Title: Taper correcting method of work-piece in grinding machine
Inventor: SAEGUSA TOSHIAKI
IPC: B24B49/02
Filed: 1980-02-19
Abstract: PURPOSE: To prevent a work-piece from being tapered by wear of a grindstone surface of the cylindrical grinding machine and transformation of the machine body by a method wherein a taper degree is judged just before the finish of a rough cutting- depth and a closed cutting-depth and after the specified lengths.  
     CONSTITUTION: The center of the cylindrical grinding machine is adapted to enable to be moved rectangularly to an axis of the work-piece and the construction is such that the centering is conducted individually by a hydraulic cylinder and a worm gear. A sizing devices are provided at two spots (positions of L and R) in the longitudinal direction of the work-piece. The sizing device itself is enough to be made a general structure. When the device is worked from a matter diameter d w   ϕ  to a diameter d 1   ϕ  by a rough grinding feed, an amount of an error of the taper is calculated from the difference of the measured values of the two sizing devices and the center is shifted by a cylinder device to cause the taper to be corrected. When the work-piece diameter is d 2   ϕ , the measurement is made again to permit a precise taper correction to be performed by the worm gear.
