Title: Control system for follow-up error
Inventor: KUMAMOTO SATOSHI
IPC: G05B19/18
Filed: 1985-03-20
Abstract: PURPOSE:To improve the contouring accuracy by correcting a feed pulse by a position error between a command position and a load position and using this corrected pulse to control the load shift amount. CONSTITUTION:A feed pulse related to a speed command is supplied to a rate converting circuit 30 from a feed pulse generating circuit 11. This pulse is also supplied to a command position counter 12 of a correction pulse generating circuit 10. While the degree of displacement of a work table is supplied to a load position counter 14 of the circuit 10 from a pulse generator 46 in the form of a pulse train. The circuit 10 calculates the difference of count value between both counters 12 and 14 and produces a polarity signal in response to the pulse of the frequency corresponding to said difference and the difference polarity. This polarity signal is supplied to the circuit 30. Thus the feed pulse supplied from the circuit 11 is corrected at the circuit 30 by the output of the circuit 10. Both the output of the circuit 10 and the output of the generator 46 are supplied to a deviation detecting circuit 32. Then a work table 44 is driven by the deviation data given from the circuit 32.

Abstract: PROBLEM TO BE SOLVED: To easily suck and remove refuse and hair within a bathtub by mounting a hose on a rubber plug and mounting a suction port on which a sucker is mounted on the head part of the hose. SOLUTION: A hollow rubber plug 1 is fitted and fixed into/to one end part (lower end part) of a hose 2 and this plug 1 is fixed by a band 5. A suction port 4 on which a sucker 3 is integrally mounted is fitted and fixed into/to the other end part (upper end part) of the hose 2 and this suction port 4 is fixed by the same band 5. When a refuse removing tool is used, the rubber plug 1 is installed within bathing hot water, the positioning of the suction port 4 is performed so as to align the surface of the water within a bathtub and the tool is sucked by the sucker 3 at the depth of the bathtub. In this state, refuse and hair floating on the surface of the water of the bathtub are sucked from the suction port 4 and are removed. When the refuse removing tool is not used, the suction port 4 is covered with a cap 7 and water leakage from the suction port 4 is prevented.

Title: Three-phase instantaneous power control type pwn control method
Inventor: ONISHI NORIO
IPC: G05F1/66
Filed: 1990-03-08
Abstract: PURPOSE:To enable efficient switching control by adopting a three-phase batch control system based on three-phase instantaneous effective power and instantaneous reactive power. CONSTITUTION:In respect to instantaneous effective power (p), a paired output pulse VA or VB is applied when the (p) reaches a level PH so that the control effective power (p) can be settled down within the range of two comparative reference levels PH and -PL to be decided according to a reference amount pr and control width, and when the (p) reaches the level -PL, a paired zero voltage output pulse VO is outputted. On the other hand, in respect to instantaneous reactive power (q), similarly to instantaneous effective power control, the operation is moved to a switching state according to the two comparative reference levels qH and -qL to be decided according to a reference amount qr and control width so that the paired output pulse VA can be outputted when the (q) reaches the qH and that the paired output pulse VB can be outputted when this (q) reaches the -qL. In such a case, when this (q) is not settled down within this control range, the range disabling the instantaneous control can be eliminated by outputting a paired output pulse VC when the (q) exceeds a much higher comparative reference range qHH. Thus, efficient switching control is enabled.

Abstract: PROBLEM TO BE SOLVED: To obtain a high single crystallization by holding the melt of semiconductor raw material for a prescribed time or longer under conditions higher by prescribed temperature than the melting point of the semiconductor raw material before the growth of a bulky single crystal from the melt is started. SOLUTION: The semiconductor raw material consists of periodic table 12th (2B) group and 16th (6B) group elements and is preferably a ZnTe compound semiconductor. If the melt at the time of start of the crystal growth is in a cluster form having various face bearings, polycrystals are liable to be formed. The melt is preferably held for >=2 hours under the conditions higher by >=30 deg.C than the melting point of the semiconductor raw material. As a result, the clusters in the melt may be finely segmented and the single crystal is obtained at a high yield by suppressing the influence of the clusters. If the semiconductor raw material is melted within a pressure vessel, the holding conditions of the melt may be optimized. The bulk single crystal may be grown at the additionally higher yield.
