Title: Data demodulator
Inventor: ENDO KAZUHITO
IPC: H04L25/40
Filed: 1990-08-27
Abstract: PURPOSE:To employ digital circuit components almost for the demodulator circuit by obtaining a maximum count for an inversion interval of a data for a prescribed period, recognizing whether an oscillating frequency at that point of time is higher than a desired frequency or lower based on the result of discrimination of quantity between the count and a prescribed value and controlling a PLL to implement locking. CONSTITUTION:A latch 71 receives an initializing signal from a timing control circuit 73 for each prescribed period and is initialized, a comparator circuit 72 compares an output of the latch 71 with a count of a counter 22 and a latch clock is fed to the latch 71 only when the output of the counter 22 is larger. Thus, a maximum count M for each inversion interval of a reception data is sequentially revised and latched in the latch 71 for two initializing pulse periods. A frequency control circuit 74 compares a maximum count M for each prescribed period with a prescribed value N and discriminates it that the oscillating frequency is higher than the desired frequency in the case of M>N and discriminates it that the oscillating frequency is lower than the desired frequency in the case of M<N and controls the oscillating frequency of a VCO 33 indirectly by controlling a phase comparator 31.

Title: Method of eliminating defects on surface of silicon substrate
Inventor: TANIGUCHI ICHIRO
IPC: H01L21/302
Filed: 1986-09-24
Abstract: PURPOSE:To enable surface defects to be eliminated by a dry etching process which is not complicated in handling or in construction of related apparatuses, by contacting chemically activated species produced by high-frequency discharge of NF3 with the surface of a silicon substrate having defects caused by reactive ion etching, for eliminating the surface defects. CONSTITUTION:Surface defects, for example those defects caused on a silicon substrate by a reactive ion etching process using CF4, can be eliminated by contacting therewith chemically activated species produced by high-frequency discharge of NF3 caused at another location. The surface defects that can be removed in this way are not only those caused by CF4 but also those surface defects caused by a reactive ion etching process using a halogen etching agent producing halogen ions. Thus, improved etching characteristics, namely approximately vertical side walls with little side etching can be ensured by a drying etching process which is not complicated in handling or construction of related apparatuses and silicon substrates freed of surface defects can be manufactured with a desirable selection ratio and a high productivity.

Title: Control method for injection molding machine and its device
Inventor: FUJIKAWA MISAO
IPC: B29C45/77
Filed: 1989-08-31
Abstract: PURPOSE:To control the resin temperature with good response and retain fluid resistance of resin optimum by comparing the pressure variation speed with the preset reference value and increasing and decreasing hydrostatic pressure of thermoplastic resin in the plasticizing process when the speed is out of the set range. CONSTITUTION:Injection pressure is sensed by a crystal piezoelectric sensor 17 and monitoring computation computed as the rate of change of injection pressure P per hour, that is pressure change speed, is computed by an operator. The computed rate of pressure change is compared with the reference pressure change speed, and the difference from the reference value (range of change) is input in a CPU. The CPU decides if the width of change is out of the set allowable range and in case it is out, other injection conditions are checked. If the conditions are all as set, the CPU controls the torque of a sevomotor 12 in the plasticizing process to stabilize the power pressure, or hydrostatic pressure, corresponding to the range of change to the resin being in the course of plasticization. The temperature of molten resin is changed quickly by said process, and fluid resistance control is controlled quickly to be in the optimum state.

Abstract: PURPOSE:To obtain an electrode material with little hydrogen generated at the time of a charge and high current efficiency and high cell conductivity by using carbon fibers with the relative integrated intensity of the nitrogen element/carbon element determined by the ESCA surface analysis and the specific resistance specified. CONSTITUTION:Carbon fibers with the relative integrated intensity of the nitrogen element/carbon element determined by the ESCA surface analysis of at least 0.04 and the specific resistance of 2X10<-3>OMEGA.cm or less are used as the electrode material of a redox flow battery. The carbon fibers with such surface characteristic are obtained by the electrolysis processing in the aqueous solution of ammonia or the like using carbon fibers as a positive electrode or the plasma processing in the atmosphere of ammonia or the like, for example. The introduced nitrogen elements exist on the surfaces of carbon fibers as the amino amide group, and the deoxidation reaction is accelerated by such carbon fiber electrode. The generation of hydrogen gas on a negative electrode at the time of a charge is thereby suppressed, and the current efficiency and electric conductivity can be improved.

IPC: G06F11/00
Filed: 1985-10-14
Abstract: PURPOSE:To prevent the display of a display device from changing suddenly and to prevent a user from recognizing it as malfunction by making delay a reset signal in a power-on reset circuit for a prescribed time with a delay circuit after a power source has been turned on. CONSTITUTION:When the power is turned on at a time t0, the input of a reset terminal 2 becomes a high level H at a time t1 by a power-on reset circuit 4. Meanwhile, the signal of the circuit 4is delayed by time tau at a delay circuit 7, and is inputted to an input terminal 6 as a high level signal H at the time t1. At a time t2, when a program runs away, a pulse from an output terminal 3 is terminated and a low level signal L is outputted from a runaway detection circuit 5, but, an influence on the inputting of the delay circuit 7 can be evaded by the presence of a buffer 8. When the input of the reset terminal 2 becomes the high level H at a time t3, the input of the input terminal 6 keeps the high level H, and therefore, the check of the display is not performed, a process being moved instantly to a normal process.
