Title: Formation of silicon nitride film
Inventor: MIKATA YUICHI
IPC: H01L21/318
Filed: 1990-06-28
Abstract: PURPOSE:To form a uniform thin film of Si3N4 on the surface of a substrate by supplying a gaseous mixture consisting of an organic compound gas containing Si and amine groups and an NH3 gas or an N2-containing gas into a vacuum tank containing plural substrates and decomposing this gaseous mixture by means of heating, etc. CONSTITUTION:Plural substrates 2, such as semiconductor wafers, are piled up in a tube furnace 1 having a heater 3 on the side wall, and the inside of the furnace is evacuated via an exhaust hole 4. An organic compound gas, such as Si[N(CH3)2]4, having a composition containing Si and amine groups and free from Cl is supplied via an air supply pipe 5 into the furnace, and an organic gas of NH3, etc., containing N and free from Cl, is mixed via an air supply pipe 6 under reduced pressure, and the resulting gaseous mixture is brought into contact with the surface of respective surfaces of the substrates 2 heated by the heater 3. The gaseous mixture is decomposed and allowed to react by heating or by means of forming into plasmic state, radiation excitation, etc., by which an Si3N4 film having uniform thickness is formed on the surface of each substrate 2. Since the raw-material gas is free from Cl in this case, the contamination of the Si3N4 film due to the formation of (NH4)Cl can be prevented.

Title: Multiprocessor system
Inventor: MIYAMOTO YUKIMASA
IPC: G06F11/20
Filed: 1990-06-30
Abstract: PURPOSE:To decide again the combination of CPUs by providing a CPU combination deciding means to decide again the number of processors according to the load states of these processors or the combination of CPUs forming each processor. CONSTITUTION:A CPU combination deciding part 2 changes the number o processors in accordance with the load states of these processors and also decides the combination of CPUs belonging to each processor. A 1-processor/3- CPU constitution is usually applied as shown in a separate diagram and therefore three processors A-C are actuated. When a control part 1 decides that the number of processors must be increased due to the increase of the load, it is decided whether a task that should be processed in a 3-CPU constitution exists or not based on the task information. A diagram shows an example where only the task that is processed by a multiprocessor B must be processed in the 3-CPU constitution. Then the part 2 leaves the CPU 4-6 of the multiprocessor B in the 3-CPU constitution and changes all CPUs except a stand-by CPU 10 into a 2-CPU constitution per processor.

Title: High frequency switching circuit
Inventor: MATSUURA SOHEI
IPC: H03K17/74
Filed: 1987-07-10
Abstract: PURPOSE:To provide a high-isolation and small-loss characteristic and to improve the frequency characteristic of switching response by connecting a variable capacitance diode to the middle point between input and output coupling capacitors and using the change of high frequency impedance of the junction capacity of the diode element itself as the switching operation. CONSTITUTION:When the bias of a bias control terminal 3 is not applied to a variable capacitance diode 4, the signal path from an input signal terminal 1 to an output signal terminal 2 is in the conductive state because the high frequency impedance of the variable capacitance diode 4 is very low. When a reverse voltage is sufficiently applied as the bias of the bias control terminal 3, the signal path is cut off because the high frequency impedance of the variable capacitance diode 4 is very high. Thus, an off through circuit is constituted which has the conductive characteristic for turning-off of a bias power source. Thus, the high-isolation and small-loss characteristic is realized, and the frequency characteristic of switching response is improved in comparison with a conventional PIN diode or transistor.

Abstract: PURPOSE:To obtain a pulse string having 50% duty from a comparator by inputting a DC voltage obtained by smoothing an input pulse string to one input of the comparator and the input pulse string to the other input. CONSTITUTION:An input pulse string is branched and inputted to a low pass filter in which frequency fc smaller than the repeating frequency (f) of the input pulse string is set up as interruption frequency to obtain a smoothed signal VR.

Title: Hot water mixing device
Inventor: TAKAHARA KAZUHIRO
IPC: G05D23/13
Filed: 1990-06-29
Abstract: PURPOSE:To obtain a hot water mixing device which maintains mixed hot water virtually at a constant temperature even when an attempt is made to change flow rate setting dramatically by allowing a control means to make ON/OFF control of both a hot water valve and a water valve in order to obtain mixed hot water at targeted temperature when a limit detection means detects either the hot water valve or the water valve is under a full-opened or full-closed limit condition. CONSTITUTION:A control device 9 determines a manipulated variable f based on fuzzy theory from deviation T-t between preset hot water temperature and detected temperature t and variation and a manipulated variable k from deviation Q-q between preset flow rate Q and detected flow rate q. When a limit detection means 15 detects full opening or full closing of a hot water valve 3 or a water valve 4, the control device 9 is arranged to mask the manipulated variable k and open and close the hot water valve 3 and the water valve 4 only based on the manipulated variable f. Only when mixed hot water at the preset temperature is called for, both the valves 3 and 4 are opened and closed. When the water valve 4 is full-opened, it is necessary to avoid a rise in the temperature of mixed hot water. Even when the preset flow rate is changed unexpectedly and the hot water valve or the water valve 4 is full- closed, the utmost effort must be made to inhibit temperature change.

Abstract: PROBLEM TO BE SOLVED: To effectively prevent unfair action such as exchanging a game control devices, by equipping a game control acknowledgement means to instruct acknowledging game control to the game control means when the validity is satisfied by the proper identification information by a validity judgement means to judge the validity of proper identifying information. SOLUTION: When a calculation device 200 is connected to this monitor first, the monitor judges the validity of the calculation device 200 by a common ID at first, and, next, sets a proper ID, which specifies the calculation device 200 to be connected to the monitor and managed by the monitor, on the calculation device 200, and, afterward, the validity of the calculation device 200 and the calculation device 200 to be managed by the monitor are judged by the proper ID. Thus, since only the proper ID set by the said monitor is stored in the calculation device 200, when another monitor is connected to the calculation device 200, the acknowledgement OK can not be given to prevent moving or falsifying the calculation device 200.
