Abstract: PURPOSE:To shorten the calculation time by directly executing numerical analysis of a differential equation by hardware and simplifying the processing before execution of operation to reduce error. CONSTITUTION:The numerical analysis calculation work of a given Poisson's equation is executed by chips, namely, hardware. With respect to the work of one chip, values psi(i,j) are taken from four peripheral chips (i,j) and an average value is obtained, and a correction value h<2>rho(i,j) recorded in the chip itself is subtracted from said obtained average value to obtain a value, and this value is stored in a certain address. Chips which perform this work are arranged at a pitch (h) and the number of prepared chips corresponds to the number of mesh points, and all chips are operated in parallel. By this constitution, the compile link processing like translation or linkage editing before execution is eliminated, and error is reduced because the preprocessing is simple, and processings of a controller and a main memory are reduced, and the calculation time is shortened.

Title: Testing machine for flexible container
Inventor: YADA FUMIO
IPC: G01M99/00
Filed: 1985-06-25
Abstract: PURPOSE:To make it possible to stably hold a flexible container (FC) to a constant compressed state over a long time, by compressing FC by upper and lower clamping bodies by rotating a screw rod by predetermined quantity. CONSTITUTION:When a motor is started, each screw rod 5 is rotated and a lift body 9 and a lower clamping body 13 rise to compress FC between the clamping body 13 and an upper clamping body 35. At this time, because a spring member 15 is interposed between the lift body 9 and the clamping body 13, even if the content in FC is received non-uniformly, the clamping body 13 is uniformly contacted with the lower surface of FC in an inclined state by the action of the member 15 and average compression force is imparted to the whole of FC. If the rotation of the screw rod 5 is stopped when FC was brought to a predetermined compressed state, the lift body 9 and the clamping body 13 are stopped at the predetermined rising position. Therefore, FC can be stably held to a predetermined compressed state for a long time.

Title: Compound semiconductor crystal growing method
Inventor: KAMATA ATSUSHI
IPC: H01L21/365
Filed: 1985-06-28
Abstract: PURPOSE:To realize a group II-VI cystal growth layer wherein the generatoin of group II vancancies are inhibited to the maximum extent by a method wherein the partial pressure whereat a group II material is supplied is kept higher than the saturation vapor pressure of the group II element and the partial pressure whereat a group VI material is supplied is kept lower than the saturation vapor pressure of the group IV element, at least on the surface of a substrate at the growth temperature. CONSTITUTION:For example, dimethyl zinc DMZ, hydrogen sulphide H2S, and an N-type impurity triethyl aluminum TEAl are grown into a ZnS:Al layer on a GaP substrate. The growth should be accomplished at a temperature of 400 deg.C, the partial pressure of the supply of DMZ of 2Torr, the partial pressure of the supply of H2S of 10Torr, where the pressure of TEAl should be 1X10<-4>Torr. Under these conditions, SA luminescence is remarkably inhibited, and a much greater controllability is attained over carrier concentration. Such an effect is attained probably because the sharp decrease in the number of positions lacking Zn enables the added Al to function effectively as donors.
