IPC: H01L21/86
Filed: 1984-04-04
Abstract: PURPOSE:To enable the formation of MgO single crystal films of high water- resistance and high acid-resistance by a method wherein a single crystal film of MgO ih which Ti dissolves is formed on an Si single crystal substrate. CONSTITUTION:A Ti 2 and an MgCl2 3 are placed in the raw-material chamber 1 of a reaction tube and each is heated to a required temperature. On the other hand, HCl and H2 gasses are introduced through a gas introduction port 4, thus producing TiCl4 gas, which is then transported to a growing chamber 6 together with the evaporated MgCl2 gas by means of Ar gas introduced through the gas introduction port. Besides, CO2 and H2 gasses are transported to the growing chamber 6 through a gas introduction port 7. Thereby, a single crystal film of MgO dissolving Ti is produced on the Si single crystal substrate loaded on a substrate holder 8. Since the crystal film thus formed is excellent in water resistance and acid resistance, it becomes possible to clean its surface; then, Si and GaAs single crystal films of high quality can be grown on the surface of that crystal film with good reproducibility.

IPC: G11C11/407
Filed: 1995-03-27
Abstract: PURPOSE:To hold a selecting state of a word line stable by providing a latch circuit in an output side of a decoder. CONSTITUTION:When output VA of address buffer out of four input of a first stage decoder circuit 8X11 are all high potentials and a high potential signal is added to a reset signal phiR, its output V1 is made a low potential, and an output V3 of 8X12 is made a high potential. Then, if a latch signal phiL is high potential, the potential of V3 is held in latch circuits 8X12, 8X13. Next, while the phiR is a low potential and the phiL is a high potential, the potential of V3 is fixed independently of variation of an address input signal. While the phiR and phiL are both a low potential, all word lines W are made non-selection independently of VA. When an ADR input is varied in the next operation cycle and one of three input VA of 8X11 is made a low potential, though the phiR, phiL is same as the cycle, the word line W is not any longer selected, and the other word line is selected.

IPC: G06F11/14
Filed: 1990-03-20
Abstract: PURPOSE:To easily set a personal computer, etc., into a system by interruption temporarily the power supply of an equipment to be initialized when no signal is received any more, and initializing said equipment after energizing it. CONSTITUTION:When the normal processing is carried out any more, no watchdog timer signal W is produced. Thus the output of the signal W is stopped. Under such conditions, a normalcy/abnormality deciding part 4 detects the stop of the output of the signal W and produces a temporary OFF signal C. Thus the power supply MP outputted from a power supply open/close part 5 is temporarily interrupted. As a result, the reset circuit of a personal computer 1 works and each circuit part of the computer 1 is initialized. Thus the runaway of the computer 1 if occurs is detected and the MP is temporarily interrupted and initialized. Then a normal personal computer, etc., can be automatically initialized and then easily set into a system.

Title: Command device for rolling stock
Inventor: KITAGAMI MASAAKI
IPC: B60T13/66
Filed: 1987-03-23
Abstract: PURPOSE:To eliminate erroneous detection and to detect a fault accurately by arranging a command system such that a check signal is outputted from an interlock section when a handle is operated to predetermined position, and a judging section outputs a fault signal if a mismatch detection signal is outputted under a condition where the check signal is inputted to the judging section. CONSTITUTION:Comparing section ER1-ER4 compare multi-system commands, and output a mismatch detection signal if they are not matched. An interlock section LOC does not output a check signal when command is switched through a handle operation and judging sections AN1-AN4 do not output fault signals even if a mismatch signal is provided. Fault signal is outputted upon provision of a mismatch signal under the condition where a check signal is provided from the interlock section LOC to the judging sections AN1-AN4 when the handle is operated to predetermined position. Consequently, fault detection signal is not outputted even if mismatch is detected due to shift of command switching timing, thereby erroneous detection is eliminated, and since the check signal is outputted at predetermined position, fault in command system can be detected accurately.

Title: System for controlling bus or line
Inventor: YONEZAKI MASASHI
IPC: G06F13/36
Filed: 1988-03-23
Abstract: PURPOSE:To lower an error rate and to heighten the percentage of success of a retry operation by controlling the output level of a power source for a driver at need. CONSTITUTION:When the retry operation is performed at the time of retry after generation of an error, a signal potential difference is set at a prescribed large value. Also, in an ordinary operation, a processor 12 changes the output of a power source box 13 for a driver/receiver correspondingly to a transfer speed desired to use at that time when a module 1 acquires the right of using a line 10, and controls the output of a driver/receiver 11, that is, the signal potential difference on the line 10. Thus, since the transfer speed on the line 10 is interlocked with the signal potential difference, it is possible to suppress the error such as a bit error at the time of transferring the data at high speed from being generated, and to heighten the percentage of success in the retry operation by setting a large signal potential difference in the retry operation at the time of generating the error, thereby, the reliability of a system can be improved.
