Title: Glass melting furnace
Inventor: KAWACHI SHINJI
IPC: C03B5/027
Filed: 1994-05-02
Abstract: PURPOSE:To prevent reduction and precipitation of a metallic oxide to be readily reduced, to suppress foaming of a component to be easily expanded and to obtain high-quality glass, by connecting each of a pair of electrodes in a glass melting furnace to an earth in such a way that the direction of an electric current flowing from the earths to the electrodes is fixed. CONSTITUTION:A glass melting furnace 1 has a glass raw material feed opening 3, an outlet 4 and an overflow part 5, 12 pairs of current-carrying heating electrodes 6 from a transformer 7 are installed on the bottom of the furnace. A connecting line 8 between the electrodes 6 and the transformer 7 is connected through current rectifiers 9, variable resistances 10 and variable reactors 11 to earths E. In the case where the reduction of a plus ion of a metal oxide becomes a problem in glass in the melting furnace 1, the earths are connected through the current rectifiers 9 to the electrodes so that only a positive electric current flows from the earths E to the electrodes 6 to prevent reduction and precipitation. In the case where the oxidation of a minus ion as an oxygen ion becomes a problem, the earths are connected through the current rectifiers 9 to the electrodes so that only a negative current flows from the earths E to the electrodes 6 to prevent oxidation.

Title: Structure of wafer receiving base for ion implantation device
Inventor: MIYAZAWA HIDEAKI
IPC: H01J37/34
Filed: 1981-07-24
Abstract: PURPOSE:To make no time to be consumed for shift adjustment of pins and absorptional exhaustion of a case, and prevent any possibility of the contamination of an ion- implantation-part container, which might be caused by opening and closing of the ion- implantation-part container, by using a wafer receiving base which has a special multiple-grooved structure so that the centers of wafers correspond to the center of an ion beam. CONSTITUTION:In the figure, a wafer receiving base which has a double-grooved structure and is used for two kinds of wafers having different diameters is illustrated. The above base has a special structure so that the centers of wafers attached to the grooves correspond to one another. Here, a wafer having a larger diameter is attached to a groove 10, and a wafer having a smaller diameter is attached to a groove 11. Since the centers of wafers and an ion beam correspond to each other when the wafers are attached to the grooves 10 and 11, two kinds of wafers with different diameters can be subjected to ion implantations successively. The above multiple-grooves structure may be a four-grooved structure, five-grooved structure and so forth. By thus combining a multiple-grooved structure or a plural number of pins, even not less than 4 kinds of wafers with different diameters can be attached to a multiple-grooved base, with the centers of the wafers and the centers of an ion beam corresponding to each other.

Filed: 1986-05-20
Abstract: PURPOSE:To improve the processing effect by allowing each processing unit to divide the processing sequentially at a branch comparatively close to a route of a retrieval tree so as to reduce number of times of divisions. CONSTITUTION:Since a state bit of an idle processor is sent in a state of logical '1', a request reception section 52 receives a time slot whose state bit is logical '1' in the request receptionable state, then a processor address of its slot is informed to a processor on the condition that the its own control flag stored in a state display storage section 51 is logical '0'. The processor divides the processing by the notice and the processor brings its own control flag to logical '1'. Further, the processor subject to division brings its own state bit to logical '0'. Since the processing division in the parallel processing division in the parallel processing of a program such as PROLOG is executed in a comparatively large unit, the division overhead is reduced to improve the processing efficiency of the computer system.
