Title: Exciting circuit for generator
Inventor: IINUMA YOSHINORI
IPC: H02P9/30
Filed: 1989-04-27
Abstract: PURPOSE:To permit the avoidance of abnormal noise generated upon stopping a generator by a method wherein the output of an automatic voltage regulator is stopped based on the detecting signal of a speed detecting means under a condition that the speed of the generator is reduced to a speed lower than a predetermined speed upon stopping the generator. CONSTITUTION:A transformer 5 is provided with the speed detecting means of a generator 2 or a frequency detector 15 at the secondary side thereof while a control contact 16, intercepting the conduction of a transistor 8 by biasing the base current thereof by the output signal of the frequency detector 15, is connected to the base side of the transistor 8 in an automatic voltage regula tor 6. Further, the frequency detector 15 puts the control contact 16 ON by the output signal thereof under a condition that the speed of the generator 2 is reduced to a speed lower than 80% of the rated speed of the generator 2. Then, the transistor 8 is put OFF forcibly and the function of the automatic voltage regulator 6 is stopped whereby the output of the same is shopped. According to this method, the possibility of generating electromagnetic abnormal noise on the decelerating process until the generator 2 is stopped may be elimi nated.

IPC: C30B11/04
Filed: 1987-05-06
Abstract: PURPOSE:To obtain the title compd. semiconductor single crystal of a stabilized quality by gradually lowering a crucible contg. a compd. semiconductor melt toward a lower low-temp. zone while fixing the temp. distribution and position of a heater to keep the cooling rate at a solid-liq. interface constant. CONSTITUTION:A main heater 31 is energized to melt a raw polycrystal material 51, and the compd. semiconductor melt is formed. After the melt is formed, the temp. at the contact part between a seed crystal 49 and the melt is raised to a temp. slightly higher than the m.p. of the compd. semiconductor to melt a part of the seed crystal 49, and the crystal is fitted to the melt. A lower shaft 27 and an upper shaft 23 are then simultaneously lowered to lower a crucible 15 along with a growth vessel 13, and a single crystal is grown from the seeding part toward the upper part. In this case, the growth vessel 13 is rotated to improve the symmetry of the temp. distribution. Since an auxiliary heater 37 is lowered along with the lower shaft 27, the crucible 15 is lowered, hence a group V element 53 is heated at a constant temp. during the crystal growth, and the vapor pressure of the group V element in the growth vessel 13 is kept constant.

Title: Information management method for atm communication system, list structure control method, buffer address management method and their system
Inventor: HASEGAWA JUN
IPC: H04L12/28
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To provide the management method for channel information table and the system where a period for maintenance processing is ensured in addition to pass processing even in the case that the cell arrival interval is reduced. SOLUTION: ATM cells arrived at a prescribed time interval are stored in a buffer memory 21. Information required for the pass processing is stored in a channel table memory 13 and an update means 15 applies passing processing to the ATM cells stored in the buffer memory 21. A maintenance management means 18 applies maintenance management to the information in the channel table memory 13. A control means 12 allows the update means to conduct passing processing for the ATM cells stored in the buffer memory 21 arrived sequentially by a shorter processing time than the prescribed time interval in the order of the arrival and allows the buffer memory 21 to consume the wait time till the passing processing is started for the cell.  When a difference between the prescribed time interval and the processing time is accumulated and reaches a time required for the maintenance processing, the control means 21 allows the maintenance management means to conduct maintenance processing.

Title: Hot-electron-transistor and manufacture thereof
Inventor: IMAMURA KENICHI
IPC: H01L29/205
Filed: 1985-05-23
Abstract: PURPOSE:To prevent the lowering of withstanding voltage between a collector and a base by forming an electron supply layer combining a potential-barrier on the N-type AlGaAs emitter side and a base electrode being in contact with a GaAs base layer. CONSTITUTION:An N<+> type GaAs emitter layer 17 is etched until it reaches an N-type AlGaAs etching stopping layer 17' while using an emitter electrode 19 as a mask. The layer 17' is removed, a base electrode 20 is shaped, and the residual layer 17 is etched until the etching reaches an electron supply layer 16 combining a potential-barrier on the N-type AlGaAs emitter side while employing the electrode 20 as a mask, thus forming a collector electrode 21 being in contact with an N-type collector region 13. Consequently, a two-element electron gas layer is formed in a GaAs base layer 15 at a low temperature even when the layer 15 is shaped in approximately 100-200Angstrom , thus increasing both carrier concentration and carrier-mobility. Accordingly, the lowering of withstand voltage between a collector and a base can be prevented.

Abstract: PURPOSE:To save wires for the device and to attain long service life by changing over the operating state of a camera section into the pre-heat state and the normal operating state by means of one cable for supplying video signal from the camera section for supervision to a monitor section. CONSTITUTION:A commercial power supply is lowered a voltage by a transformer 4 in the monitor section 1 at first, the power is rectified and smoothed by a rectifier and smoothing circuit 5 to obtain a DC power supply. On the other hand, a reference voltage is formed by a reference voltage generating circuit 12 from a voltage applied via a cable 3 in the camera section 2. In order to changeover the state, a voltage discriminating circuit 17 compares a reference voltage from the reference voltage generating circuit 12 with a voltage dividing a supply voltage from the cable 3 at first to discriminate whether the voltage applied from the monitor section 1 via the cable 3 is a stand-by voltage or the operating voltage. Further, when the stand-by voltage is applied, the circuit is changed over so that the stand-by changeover circuit 18 is controlled and a pre-heat voltage is generated from a per-heat voltage generating circuit 13.
