Title: Control device for vehicular automatic transmission
Inventor: KOYAMA HIDEO
IPC: F16H61/16
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To precisely perform transmission prohibition in up-shifting from the second speed to the third speed when slippage occurs in up-shifting from the first speed to the second speed by prohibiting up-shifting of an automatic transmission for a second specified time in the case that a shifting time counting means counts the up-shifting time shorter than a first specified time. SOLUTION: When a shifting time counting means M9 counts up-shifting time of an automatic transmission shorter than a first specified time, occurrence of slippage is determined during the up-shifting. A transmission prohibition means M3 prohibits further up-shifting of the automatic transmission for a second specified time without depending upon normal determination of a slipping condition by means of a slipping condition determination means M2. The first specified time is so set as to surely detect presence of slippage during up- shifting. The second specified time is so set as to sufficiently enable transmission prohibition of the automatic transmission 1 based on determination of the slipping condition by means of the slipping condition determination means M2.

Title: Block replicator of ion implantation bubble device
Inventor: BETSUI KEIICHI
IPC: G11C11/14
Filed: 1982-12-28
Abstract: PURPOSE:To simplify structure and to reduce the independence of pulse width of cut current by forming a holed conductor pattern between a major line and a minor loop and then forming an area in which no bubble can be included on an intermediate position of one side parallel to the holed pattern. CONSTITUTION:A hole 12a is formed on the conductor pattern 12 between the major line 10 and the minor loop 11 and the area 13 in which no bubble can be included is formed on the intermediate position of a side c-d. A bias magnetic field is formed upwards and perpendicularly to the surface of paper. If current of an I1 direction is made flow into the pattern 12 when a bubble reaches a point (a), the bubble 14 is extended along a side a-b. The direction of a driving magnetic field is about 270 deg. at that time. If current I2 is made flow when the magnetic field reaches close to 315 deg., the bubble 14 is drawn to a side c-d and is formed like a bent shape. At that time, a magnetic field cancelling the bubble is generated in the side a-b and the bubble 14 is divided into bubbles 14', 14''. Since a cusp (c) and a tip (d) are made absorbing state when the magnetic field is 90 deg., the bubbles 14', 14'' are absorbed to the points c, d if current is 0 and then transferred on the loop 11 and the line 10 respectively to be detected.

IPC: H01L21/58
Filed: 1983-12-02
Abstract: PURPOSE:To improve the heat sink efficiency of a semiconductor device by securing a semiconductor chip through a metal plate having a thermal conductivity higher than an insulating substrate on the substrate. CONSTITUTION:A semiconductor chip 5 is secured through a metal plate 6 of copper having an area larger than the bottom area of the chip to an insulating substrate 1 made of BeO or Al2O3. Since the plate 6 has thermal conductivity higher than the substrate 1, heat stream from the chip 5 expands in not only the thicknesswise direction but also inthe lateral direction of the plate 6 to increase the sectional area of the heat stream, and flows to the substrate 1. Accordingly, the heat stream sectional area increases in the substrate 1, and the thermal resistance of the portion of the substrate 2 can be reduced.

Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To surely recognize a pattern consisting of a combination of a couple of reflecting bodies, having different reflection factors without being affected by variance in photocurrent conversion elements. SOLUTION: The reflecting bodies combined, having a large and a small or a small and a large reflection factors, are irradiated with illumination lights from LEDs 11 and 12. Reflected lights from the reflecting bodies are made incident on phototransistors 14 and 15 as photocurrent conversion elements. The phototransistors 14 and 15 are connected in series, and when the photocurrent is larger on the side of the phototransistor 14, the current flows from the phototransistor 14 to a resistance R7, but when the photocurrent is larger on the side of the phototransistor 15, the current flows from the resistance R6 to the phototransistor 15, so that the direction of the current at (a) is reversed according to the large/small relation between the phtocurrents.  Here, a voltage comparator 16 detects the direction of the current at (a) and has a signal output, showing whether the reflection factors of the pattern is large and small, or small and large.

Title: Driving system for liquid crystal element
Inventor: ITO AKIHIKO
IPC: G02F1/133
Filed: 1985-10-14
Abstract: PURPOSE:To attain multiplex driving capable of indicating gradation by a ferrodielectric liquid crystal by inverting the polarity of a signal to be impressed to a signal electrode during a selecting period to turn positive and negative voltages to the same level, and impressing the signal whose voltage is modulated by gradation data. CONSTITUTION:Since the voltage of a signal electrode waveform 132 to be impressed during the non-selection period of the liquid crystal element is always lower than Vth1, Vth2, the status of the liquid crystal element in the selection period is also held in the non-selection period almost without any change. A scanning electrode 141 and a signal electrode 142 can be similarly driven by setting up the waveforms of both the electrodes 141, 142 to the same phase and setting up the driving voltage condition of a scanning electrode waveform to (¦V2¦-¦V1¦)>¦Vsat2¦, V1>sat1 and (V1-V3)<Vth1. The number of gradation levels can be optionally changed by selecting the number of divisions of a volt age 0-V3 volt and 0--V3 volt to be a voltage for a signal electrode side waveform 132. Consequently, the gradation indication driving of the ferrodielectric liquid crystal can be attained.
