Title: Method for laying out semiconductor integrated circuit
Inventor: IWASAKI TADASHI
IPC: G06F17/50
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To improve the operating frequency of an integrated circuit by suppressing the wiring delay time of a signal transmission time by calculating the value of a specific formula from the interval between adjacent wirings and the corresponding wiring length, and connecting the input and output of a functional cell so that the value of the formula becomes small. SOLUTION: A functional cell for realizing a plurality of fundamental logics is disposed, and the input and output terminals of the cell are connected by wining. Then, an initial value '1' is substituted for the variable (n) for counting the number of repeated times of wiring. Then, adjacent wiring interval di of all the signal wirings except the clock signal wiring is extracted, and the wiring length ai disposed in parallel at the interval di is extracted. The formula is calculated for all the wiring lengths of the wirings, and individual signal wirings are sequentially rewired so that the value of Cp becomes small. Further, the number of repetition of the rewirings is set, for example to five times as the upper limit value, and the number of times of the wirings for the entire integrated circuit is counted, and when the counted value becomes 6, the rewirings process is finished.

Title: Pulley having high friction surface
Inventor: TAKAHASHI HIROSHI
IPC: F16H55/38
Filed: 1987-01-20
Abstract: PURPOSE:To obtain stable quality by mixing metal, ceramic and resin materials in particles, molding the mixture in a die under high temperature and pressure to form a pulley, and effecting chemical corrosion to dissolvingly remove only metal particles exposed in the outer surface. CONSTITUTION:Metal particles 4 exposed in the surface of a pulley 1 is dissolved to form recesses at the positions where the metal particles 4 existed in a plastic material 2 which is a basis. Therefore, when a metal belt is applied around the pulley 1 to be driven, contact of the peripheral surface of the pulley 1 and the peripheral surface of the belt causes abutment of the belt surface with the corroded surface to impart resistance against rotation which provides stability of the driving force. As remaining ceramic particles 3 have flat surfaces, rotation of the pulley causes no damage to the surface of the belt driven for rotation, assuring satisfactory protection of the belt during long use. Furthermore, die casting permits mass production as well as assures stable quality.

IPC: G06F1/18
Filed: 1989-01-19
Abstract: PURPOSE:To allow one connector to correspond to use of plural packages and to prevent a device body from being expanded in size by providing a means capable of switching I/O signals to/from the package by a signal from another part of the device on the backboard. CONSTITUTION:Each buffer 3 switches data signal lines 401 to 422 from other parts of the device and connects the selected signal line to the connector 2. When the device is allowed to correspond to two kinds of packages and either one of SELECT signal lines 31, 32 is set up to logic 1 in accordance with the package inserted into the connector 2, either one of data line groups, 401, 411, 421 or 402, 412, 422 is connected to the signal outputted from the connector 2. In case of inserting a function expanding package, either one of the SELECT signals 31, 32 uses a signal formed by manually switching the switch in the device or electrically switching it by software. Consequently, the same connector can use two kinds of packages having respectively different I/O signals and the increment of the mounting capacity can be suppressed.

Title: Fabrication of semiconductor device
Inventor: SASAKI YUJI
IPC: H01L21/28
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To eliminate missing or generation of voids in an Al alloy film formed by annealing,a laminate of thin Si film and Al film. SOLUTION: (111) orientation of Al alloy film is enhanced by setting the ratio of thickness of a thin film of Si to a thin film of pure Al in the range of 4-8%. Since a most compact face of a face-centered cubic lattice having lowest surface free energy, i.e., the (111) face, is directed toward the surface of Al alloy film extending in parallel with the underlying layer, the (111) face facing the grain boundary is decreased and missing or generation of voids is suppressed along that face. When such Al alloy film is employed as the upper electrode 12a of an MIS type capacitor, etchant is prevented from intruding into the upper electrode 12a even when a via hole 15 is made through an interlayer insulation film 13 of SiN covering the upper electrode 12a by etching and thereby no pinhole is generated in a capacitor insulation film 9.  Consequently, an MIS type capacitor is protected against dielectric breakdown.

Title: Through-current preventing circuit of output inverter
Inventor: AOKI HIROSHI
IPC: H03K17/16
Filed: 1985-01-24
Abstract: PURPOSE:To prevent a through-current with a few elements by connecting a constant current circuit between P and N channels receiving a common input signal to their gate and connecting the output of the P and N channels to a gate of the P and N channels of an output inverter respectively. CONSTITUTION:When a level of a terminal (a) is inverted from 1-0 as shown in a figure (a), a P channel P2 is turned on and a gate capacitance C1 is charged rapidly as shown in a figure (b). When the level of the terminal (a) is inverted from 0-1, the N channel N2 is turned on. Thus, a gate capacitance C2 is discharged rapidly as shown in a figure (c). On the other hand, the gate capacitance C1 is charged slowly by a constant current through the N channel N3 as shown in the figure (b). Thus,both the P channel P1 and the N channel N1 are turned off for a time t4. The P channel P1 and the N channel N1 are turned off without fail when the level of the terminal (a) is inverted to prevent the through-current. Further, the circuit is effective without being affected by the operating power supply voltage for a solar battery for the power supply especially.

Abstract: PURPOSE:To obtain a high-quality output image by a method wherein whether a graphic image is drawn on a graphic image memory or on a character image memory is discriminated, and the image data approximated and stored in the character image memory is synthesized, as required, to be outputted. CONSTITUTION:Whether a pixel is perfectly inside a character boundary is discriminated. If the pixel is not across the character boundary and perfectly inside the character boundary, it is stored in a graphic image memory 5. On the other hand, when the pixel is not perfectly inside the character boundary, whether it is perfectly outside the character boundary is discriminated. If the pixel is outside the boundary, the pixel should be clipped so as not to come to an image. Therefore, the processing of the pixel is finished without drawing. On the other hand, when the pixel is not perfectly outside the character boundary, it is across a character profile. Thus, the graphic image is clipped at the character image profile. At this time, graphic image data in the pixel data is not drawn in the graphic image memory 5 but in a character image memory 4.

Abstract: PURPOSE:To obtain a recording material superior in information recording/ erasing properties, by using a material wherein a change in optical characteristics is locally induced by an endothermic reaction. CONSTITUTION:As a concrete material, a metal and an alloy of semimetal element ranging from Ib to IVb in the periodic table, especially an alloy of 1.45 or more average electron concentration, is used. Particularly, a beta' phase (an order phase of CsCl type) formed in an alloy of Ag-Zn series produces a pink, thus resulting in a remarkable change in an optical characteristics from a zeta phase (silverwhite) existing in the aforesaid alloy series. With an initial state of the zeta phase in the alloy, a transformation zeta beta' corresponds to a recording, and a transformation beta' zeta is an erasing. In this relation, since the transformation zeta beta' is quenched after completion of a transformation zeta betato establish the beta' phase, it is desirable that the transformation zeta beta is substan tially endothermic. It is the most desirable, however, as a recording material that both the above transformations are made endothermic by adding Al, Ga, In, Sn, Sb in the range of 10wt%.
