Abstract: PURPOSE:To improve the rate of monocrystallization of a semiconductor layer, by a method wherein a part used as a seed crystal is made to project from the other part so as to be even with the surface of an insulation layer on the occasion when a part of a single crystal layer covered with the insulation layer is exposed, then a semiconductor layer is grown on the whole surface containing the above exposed part, and the semiconductor layer grown by using the exposed part of the single crystal layer as the seed crystal is monocrystallized. CONSTITUTION:A semiconductor layer 411 is piled on an insulation layer 401 surrounding a semiconductor single crystal layer, and the whole surface is covered with an insulation layer 402. Next, a semiconductor layer 412 is further  piled thereon, and is then monocrystallized in the following way. An opening is  made in a prescribed position of the insulation layer 402, the semiconductor layer 411 is exposed therein, a semiconductor layer 42 to serve as a seed crystal is buried therein, and the semiconductor layer 412 is piled thereon. Then, annealing is applied, beginning with the semiconductor layer 42, and by using this layer as a seed, the entire layer 412 is turned into the single crystal sequentially. By this constitution, the piled semiconductor layers can be easily monocrystallized, and the alternate lamination of semiconductor layers as occasion calls is simplified.

Title: Detecting circuit for open phase of encoder signal
Inventor: HORISAKI KAZUHIRO
IPC: G01D5/245
Filed: 1989-06-14
Abstract: PURPOSE:To enable detection of phase omission even when both phases A and B are omitted, by delivering a detection signal when one or both of the phases A and B are omitted, on the basis of an output of a count value of a phase X and an AND output of count values of the phases A and B. CONSTITUTION:8-bit shift registers (SR) 1a and 1b and a 2-bit SR 6 count a phase A of an encoder signal, a phase B different by 90 deg. from the phase A and a phase Z delivered every one rotation of an encoder, respectively. A D flip-flop (FF) 5 delivers a detection signal when one or both of the phases A and B are omitted, on the basis of an output of a count value of the phase Z and an AND output of count values of the phases A and B. When the count value of the phase A or the phase B exceeds a prescribed number, all the count values are reset by an NOR circuit 3. The DFF 5 is designed to be preset on the basis of an output of the SR 6, and when both of the phases A and B are omitted, the SR 1a and 1b do not count incrementally. Therefore the SR 6 is not reset and, consequently, phase omission of both of the phases is detected.

Title: Descaling method for steel plate
Inventor: ASAI HITOSHI
IPC: B21B45/06
Filed: 1980-10-28
Abstract: PURPOSE: To make descaling uniformly and improve work efficiency by coiling a hot-rolled steel plate at specified low temperature, and after cold-rolling at specified low rolling reduction passing it through brushing rolls.  
     CONSTITUTION: A hot-rolled steel plate 1 coiled at low temperature of ≤500°C after hot rolling is uncoiled from an uncoiler 2, and cold-rolled and cold-worked at ≤20% rolling reduction to form fine cracks in scales on the surface of the steel plate. The plate is then descaled by passing through a mechanical descaler 6 provided with brushing rolls 4 such as wire brushes and supporting rolls 5, and coiled to a coiler 7. The rolling reduction is specified since if it is ≥20%, descaling becomes difficult as scales are thrusted into the steel. Regarding coiling temperature, if temperature becomes ≥500°C, descaling rate at the edge of the hot-rolled steel plate declines.

Filed: 1984-07-25
Abstract: PURPOSE:To obtain a simple, inexpensive voltage detecting circuit with good detection precision and high reliability by constituting the titled circuit of resistances, diodes, and a photocoupler. CONSTITUTION:The resistance 19 and diodes 20-22 for level shifting are connected forward, and a diode 22 is connected to the anode of the light emitting diode 9 of the photocoupler.
