Title: Production of fine powder
Inventor: IWAMA SABUROU
IPC: B01J19/08
Filed: 1981-11-05
Abstract: PURPOSE:To produce fine powder efficiently by applying electron beams alternately to plural pieces of wire like or barlike materials thereby heating the materials locally to high temp. CONSTITUTION:After the inside of an irradiating chamber is evacuated, an atmosphere gas necessary for formation of the intended fine powder is supplied through a piping into the irradiating chamber. The degree of vacuum in the chamber is measured and the gaseous atmosphere is maintained at prescribed low pressure. Thereafter, the irradiating direction of electron beams is fluctuated by operating a deflection coil 4a provided in an irradiating system for the electron beams to oscillate the electron beams at a specified period at an amplitude L so that the beams are applied alternately upon the preceding ends of respective materials 10a-10e. Therefore the electron beams are irradiated intermittently to the preceding end parts of the materials 10a-10e, by which the respective preceding end parts are heated to melt, and the materials are evaporated from the surfaces of the molten parts. The preceding end parts are located within the amplitude L of the beams by letting off the materials from rolls in conformity with the rate of evaporation.

Title: Method and device for test of memory
Inventor: ISHII HIDEO
IPC: G06F11/22
Filed: 1990-07-04
Abstract: PURPOSE:To decide a fixed fault of a memory array by checking a defective position of the row address connected to the memory array. CONSTITUTION:A defect is detected in the 2nd read data of the n-th row address read out of a 1st comparison means 9 when the data on the n-th row address of a memory array 1 is read out. In such a case, the defective position information on the array 1 is stored. Then the defective position information on the 2nd read data on the 1st row address is compared with that of the 2nd row address by a 2nd comparison means 11 when a defect is detected in the 2nd read data on the (n + 1)-th row address of the array 1. When the coincidence is secured between both defective position information, a fixed fault is decided. Thus the fixed fault is automatically decided.

Filed: 1989-07-11
Abstract: PURPOSE:To speed up the changeover of transmission reception by allowing a master station to use a clock generated by a DPLL circuit from a reception signal for only a reception clock and allowing a slave station to use a clock generated by the DPLL circuit both for transmission and reception clocks. CONSTITUTION:A transmission control section 4 controls a driver 8 to be enable and a receiver 9 to be disable. Thus, a signal synchronously with a transmission clock signal 20 of a master station 1 is outputted to a transmission line 25 and inputted to slave stations 2-n. A transmission control section 10 of the slave station 2 controls a driver 13 to be disable and a receiver 14 to be enable and an output signal from the master station 1 is inputted to a reception control section 11 as a reception signal 27. The reception signal 27 is also inputted to a digital phase locked loop(DPLL) circuit 12 and a transmission reception clock signal 28 synchronously with the reception signal 27 is generated after the synchronization of the DPLL circuit 12 is established. Since the synchronization is always taken, the synchronization establishment wait time of the DPLL circuit is not almost required and the changeover of transmission and reception is quickened.
