Abstract: PURPOSE:To improve the success rate of blowout, and to enhance reliability by forming a passivation film, to which a window is shaped, to a section corresponding to a region to be blown out in a fuse element and forming a resin layer for protection after the fuse element is blown out. CONSTITUTION:A polycrystalline silicon layer is patterned on a field oxide film 11 shaped on a semiconductor substrate 10 to form a fuse element 12. An inter- layer insulating film 13 is formed, and conductor wiring layers 15a, 15b connected to the fuse element 13 through contact holes 14a, 14b are shaped. A passivation film 16 is formed, and a window 17 reaching to the inter-layer insulating film 13 is bored, thus constituting a redundant circuit. Laser beams are projected through the window 17, and a region to be blown out in the fuse element 12 is blown out. A resin layer 18 is shaped, thus obtaining a semiconductor device 20. A polyimide resin having the shielding action of alpha-rays is used as the resin layer 18. The sufe element 12 can be blown out at a very high success rate because the window 17 is bored.

Abstract: PURPOSE: To reduce the water pressure pulsation of hydraulic machinery by prescribing the shape of the inlet part of a draft tube.  
     CONSTITUTION: The shape of this draft tube 3, (a) permits a conical spreading pipe to be arranged without forming a direct circular pipe at the inlet part of a draft fube 3. (b) The length H of the conical spreading pipe part at the inlet part is set at 0.6 D-H≤1.2 D for the diameter D of the inlet part of the draft tube 3. (c) The angle θ of spreading of the pipe wall 6 of the conical spreaded pipe at the inlet part is prescribed within the range θ=15W22°. When such prescription is formed, if water stream has revolution characteristic, a sharp pressure increase is formed at the center of the inlet part of the draft tube 3, and thus, the dead water core range can be destroyed rapidly, and thus the peak of water pressure pulsation can be reduced to about 1/3 of the conventional hydraulic machinery.

Abstract: PURPOSE:To decrease the voltage applied on a driver for driving a liquid crystal panel by the method for simultaneously selecting plural lines. CONSTITUTION:This device comprises a liquid crystal panel 1, a controller 2, a common driver 3 and a segment driver 4. The controller 2 generates an orthogonal signal represented by a set of orthogonal functions, performs the product-sum arithmetic operation using a set of orthoganal signals and a set of pixel data and generates the product-sum signal in accordance with the result. The common driver 3 applies a row driving wave form having a prescribed voltage level (+Vr, Vo, -Vr) to the row electrode of the liquid crystal panel 1 by group-sequential scanning for every selection period according to the orthogonal signal. The segment driver 4 applies a column driving waveform having a prescribed voltage level (V1-Vn) to the column electrode of the liquid crystal panel 1 synchronized with groupsequential scanning according to the product sum signal. The common driver 3 outputs a row driving waveform on a comparatively high voltage level supplied from a high voltage power source (+VLC, -VLC) while the segment driver 4 outputs a row driving waveform on a comparatively low voltage level supplied from a low voltage power source (VDD, GND).

Filed: 1989-02-14
Abstract: PURPOSE:To attain low power consumption by providing a delay element between a control terminal controlling the output state and a pulldown (pullup) transistor(TR). CONSTITUTION:When an L level is provided to a control terminal 205, a signal supplied to the control terminal 205 turns off a pulldown TR 202 after a switching time of a delay element 203 being a buffer. When the level of the control terminal 205 is selected to an H level conversely, the signal supplied to the control terminal 205 is delayed by a switching time of the delay element 203 being a buffer, turns on the pulldown TR 202, resulting that the output terminal 206 goes to an L level. Thus, the short-circuit current flowing through the pulldown (pullup) TR is decreased in the signal switching of the control terminal in the pulldown (pullup) output driver to attain low power consumption.
