Title: Phase error detection circuit
Inventor: WATANABE KYOJI
IPC: H03L7/095
Filed: 1986-03-07
Abstract: PURPOSE:To improve the transmission quality and reliability by detecting a control signal controlling the oscillation frequency of a voltage controlled oscillator of a phase locked loop (PLL), comparing the signal with a reference voltage and outputting an alarm signal so as to detect the increase in a phase error even with the PLL in the locking state. CONSTITUTION:A control signal detection circuit 2 detects a control signal VC controlling the oscillated frequency of the voltage controlled oscillator 14 and a comparator circuit 3 outputs an alarm signal VA when the output voltage of the control signal detection circuit 2 exceeds a preset reference voltage VR within the frequency holding range of the PLL 1. The circuit 2 acts like an absolute value circuit with the relation of VD=V>=C at VC>0, VD=-VC at VC<0, that is VD=VC in the relation of resistors R1=R2=R3=2R4=R5. The comparator circuit 3 having an amplifier 31 compares the voltage VD with the reference voltage VR and when the voltage VD exceeds the reference voltage VR, the alarm signal VA is outputted.

IPC: H01L21/316
Filed: 1982-03-27
Abstract: PURPOSE:To enable to perform surely and simply screening of gate oxide films at the wafer phase, and to contrive to enhance reliability of the semiconductor device by a method wherein the gate oxide films are formed on the wafer, electrode material layers are formed at gate electrode formation programing parts on the films thereof, and a voltage is applied to said electrode material layers before the diffusion layers of a source, a drain, etc., are to be formed. CONSTITUTION:After the wafer 11 is selectively oxidized to form field oxide films 12, a thermal oxidation treatment is performed to form the oxide films 13 to be used as the gate oxide films in respective element regions isolated by the field oxide films 12. Then the electrode material layer, the phosphorus doped polycrystalline silicon layer for example, 14 is stacked on the whole surface, and the high voltage is applied between the electrode material layer 14 and the wafer 11. Because no diffusion layer of source, drain, wiring, etc., is formed on the wafer 11 in this phase, the voltage sufficiently higher than the working electric power source voltage of the LSI can be applied, and inferiority of the gate oxide film 13 is destroyed nearly completely. Accordingly the high reliable LSI product can be obtained, and moreover, an inferior chip to be caused by the gate oxide film can be removed in the wafer stage.

That is, a film of silicon oxide is formed on a substrate 4 and the heat treatment process is applied thereto. Next, the heat treatment process is applied to it after immersing it in a solution of lead acetate and the heat treatment is applied to it after immersing it in a solution of manganese acetate, further the heat treatment is applied to it after immersing it in a solution of natrium acetate.

IPC: H01L21/268
Filed: 1980-04-18
Abstract: PURPOSE:To accurately control the resistance value of an ion-implanted layer so as to produce a given high-resistance layer by a method wherein a polycrystalline semiconductor injected with oxygen or carbon ions is irradiated with a pulse laser or electron beam in a high vacuum. CONSTITUTION:For example, the resistor-forming region of an FET produced in the polycrystalline Si process is exposed and injected with oxygen or carbon ions 7 to provide an ion-implanted layer 6. Then, said cell 10 is connected with an NC system or monitoring resistor 9 and arranged in a highly vacuum container 11. Under said condition, the cell 10 is irradiated with a pulse beam 8 by using an Nd-YAG laser, for example, in order to vary (decrease) the resistance value of the implanted layer 6. The irradiation intensity is lowered from the point of time when the resistance value has approached to the preset value, and the irradiation is stopped when the resistance value has reached the preset value. Thereby, a polycrystalline Si high-resistance layer can be formed while being highly accurately controlled, and the production of an E/R inverter, for example, can be facilitated.

Title: Modem capable of calling
Inventor: TOYAMA MAKOTO
IPC: H04L27/00
Filed: 1994-02-10
Abstract: PURPOSE:To realize simultaneous communication between a telephone call and computer communication with one telephone line by timedivisionally transmitting/receiving compressed sound signal and computer communication signal. CONSTITUTION:The sound signal found by a transmitter 31 is fetched into a compression circuit 211 in MODEM 2 on a real time, is converted into the compression sound signal of short time and is transmitted to a transmission circuit 21. In a compression method, a time base can merely be shortened so as to shorten the signal. Since a compression rate is limited, it is preferable to make the signal into PCM or to digitalize it, to compress it and to modulate it again into an analog signal. A digital signal from a computer 1 is fetched into a modulator in MODE 2, is modulated into an AC analog signal toward the telephone line and is transmitted to a transmission circuit 210 in parallel to compression. The transmission circuit 210 time-divisionally transmits the compressed sound signal and the modulated signal from the computer to the telephone line. Thus, computer communication and the regular call can be conducted with one telephone line.

Title: Production of hot rolled material consisting of alpha+beta type titanium alloy
Inventor: SENUMA TAKEHIDE
IPC: C22F1/18
Filed: 1985-03-14
Abstract: PURPOSE:To produce a hot rolled material of an alpha+beta type titanium alloy having uniformly dispersed fine alpha grains and high quality by subjecting an alpha-beta type titanium alloy to a heat treatment under adequate conditions and to working at a high ratio in an adequate temp. range then annealing the alloy in a specific temp. region. CONSTITUTION:The alpha+beta type titanium alloy is heated to the temp. of beta-transus or above to suppress the precipitation of the alpha-phase. The alloy is then cooled at <=15 deg.C/sec average cooling rate from the beta-transus down to 800 deg.C to prevent the formation of martensite. The alloy is worked at least at >=70% in the temp. region from the beta-transus down to 650 deg.C within 10min upon passage of the beta-transus in the above-mentioned cooling process so that the fine alpha grains are uniformly precipitated. The alloy after the working is then annealed in a 600-800 deg.C range by self-annealing etc. The hot rolled material consisting of the alpha+beta type titanium alloy having excellent ductility and high quality is thus obtd. at a high yield and low cost.

The temperature signal is inputted to a computing device, and the average temperature of each pipe group is calculated. In the computing device, a previously set temperature difference range, being applicable to each pipe group, is stored. When a difference between the temperature of each coal feed pipe 8 and the average temperature of each pipe group exceeds the temperature difference range, the coal feed pipe is decided to be blocked, and with shut-off valves 14 and 15 shut off, a lodging substance present between the valves is removed.
