Title: Window opening shape of external pickup metal electrode of semiconductor element
Inventor: WAKAMOTO FUSHINOBU
IPC: H01L29/417
Filed: 1983-10-28
Abstract: PURPOSE:To prevent a pad electrode from corroding by providing a window opening shape with a smooth curved structure like arcuate at the inner wiring side and with a slender slit at the end in an acute angle at the reverse side. CONSTITUTION:Ultrafine particles of silicon bonded to a pad electrode in dicing step to drying step, wear chips of dicing saw and impurities in the atmosphere are secured to corners B, C, D farther from the corner A near the inner wirings by utilizing the surface tension of water. Even if a separation occurs between resin and the surface of a chip due to the use for a long period and a water film is produced in the boundary, acute corner and slender slit are formed at the corner, thereby securing the produced water film to the corners of B, C, D farther from the inner wirings. Thus, even if the pad electrode is corroded, it occurs at the farther portion from the inner wirings. Accordingly, the lifetime reaching the disconnection can be increased.

Title: Power amplifier
Inventor: HORI FUMIO
IPC: H03F3/21
Filed: 1981-12-17
Abstract: PURPOSE:To attain a large output simply and to reduce heat loss, by connecting ground side of a load to a positive or negative terminal of both polarity power supply with a large input signal and connecting the ground of the load to the common point of the power supply with a small input signal. CONSTITUTION:When an input signal ei is smaller than a positive power supply Vcc, a switch circuit SW is connected to a common point (b) of both polarity power supplies Vcc, Vcc', and the amplifier acts like a conventional class B amplifier. When the signal ei is higher than the power supply Vc, the circuit SW is connected to the negative terminal (c) of the power supply Vcc'. When the signal ei is larger than the power supply Vcc', the circuit SW is connected to a positive terminal (a) of the power supply Vcc. Thus, the maximum output is four times in using the same power supply voltage. Since the power supply voltage is low with a small output and the power supply voltage is larger with a large output, the same efficiency as that at the maximum output can be obtained with the small output. Thus, the heat loss is small, and large output, high efficiency and low loss can be realized at the same time.

Title: Photoengraving process in silk screen printing and laminated sheet used for the same
Inventor: MAEDA HIKARI
IPC: B41C1/14
Filed: 1986-08-30
Abstract: PURPOSE:To enable the photograving process, without an aspirator by sticking the surface of an adhesive layer of a positive sheet which is peeled off a protective layer to a photosensitive resin film which is formed on the screen, followed by exposing it. CONSTITUTION:The positive sheet 15 exposes the adhesive layer 4 by peeling off the protective film layer 5 resulted in enabling to stick it with the photosensitive resin film. The positive sheet 15 is stuck with the photosensitive resin film 9 which is shaped in the screen by applying it to a screen frame 10 utilizing the adhesive layer 4. Thus, the positive sheet 15 is stuck easily and completely with the photosensitive resin film 9, followed by exposing the film 9. The photosensitive resin film 9 becomes insoluble to a solvent in the exposed part (t) due to a difference of photoenergy between the exposed part (t) of a translucent portion 8 in the positive sheet 15 and a shading part (n) which does not pass a light in said sheet 15. The photosensitive resin film is treated with the solvent after peeling off or during sticking to the positive sheet 15, thereby remaining the exposed part (t) of the photosensitive resin film which converts to passive state against the solvent and forming the shading film against an ink, resulted in forming a printing plate.
