Title: Television receiver
Inventor: TSUDA HIDETOSHI
IPC: H04N3/185
Filed: 1981-07-11
Abstract: PURPOSE:To obtain a stable horizontal deflection without using a stabilized power supply, by providing a deflection current compensating means controlling the deflection current and the amplitude of horizontal collector pulse to a constant value and a pulse voltage compensating means for a horizontal deflection circuit. CONSTITUTION:An unstabilized voltage VA of an output of a power supply rectifying circuit 2 is applied to a horizontal deflection circuit via a primary winding L1 of a flyback transformer T1. A diode modulator 7 even with the voltage VA controls a deflection current flowing to deflection yoke L2 by controlling a voltage Vm across a capacitor C5. A current control circuit 8 changes the inductance of a secondary winding L5 by controlling the current supplied to a primary winding L6 of a transformer T2 in response to the voltage VA. A current detection circuit 9 controls the Vm to keep the deflection current constant in response to the VA.

Abstract: PURPOSE:To obtain a hetero bipolar transistor having excellent characteristics by forming a reaction preventing layer not reacting with a gas used for vapor growth, on a silicon substrate, by forming an opening part opening on the reaction preventing layer and exposing an active region of the silicon substrate, and by forming a silicon carbide film on the silicon substrate in the opening part. CONSTITUTION:A P-type base region 4 is formed by ion-implanting boron in an active region 21 of a silicon substrate 1. By a chemical vapor growth (CVD) method, a silicon oxide film 31 is formed on the whole surface. Subsequently, a titanium nitride film 5 is deposited as a reaction preventing layer 5 on the whole surface by a conventional sputtering method. In order to form an emitter, first a resist pattern having an opening on the titanium nitride film 5 on the active region 21 is formed and the titanium nitride film 5 and the silicon oxide film 31 are removed by etching from the opening, so as to form an opening part 51 exposing the base region 4. On the base region 4 in the opening part 51, a silicon carbide film 6 is made to grow epitaxially by the CVD method using trichlorosilane and methane. On the occasion, phosphorus is doped to make the film be of an (n) type, and the silicon carbide film 6 having grown epitaxially becomes an emitter region.

Title: Auxiliary steam control method for electric power plant
Inventor: SAITO SHUJI
IPC: F01K13/02
Filed: 1987-05-06
Abstract: PURPOSE:To make a stable control of auxiliary steam under maintaining the safety operation of each electric power plant by controlling an auxiliary steam adjusting valve using a master controller into which an operating state of each electric power plant and a header pressure of the auxiliary steam are inputted. CONSTITUTION:Pressure in an auxiliary steam header 5 is detected by a pressure transmitter 10 and inputted into a master controller 12. The master controller 12 into which the operating state of each electric power plant A-C is also inputted makes controlling computation to control the pressure in the auxiliary steam header 5 at a certain pressure based on these said signals. The computed signal is delivered to auxiliary steam adjusting valves 6A-6C through auxiliary steam adjusting valves 11A-11C of each electric power plant A-C. Due to this measure, the master controller 12 controls the pressure in the auxiliary steam header 5 and transmits this control state of the auxiliary steam to a control device 13 of the electric power plants. Therefore, controlling stably the pressure in the auxiliary steam header 5 even if equal load state occurs at the starting time, enlargement of extracted steam from each electric power plant A-C can be prevented.

Abstract: PURPOSE: To promote separation and ascension of bubbles by putting thereof together so as to be enlarged in diameter through colosion and turbulenece caused in a curved passage comprising a plurality of upward and downward streams formed by faffles provided side by side in the passage to the pump from the upward passage.  
     CONSTITUTION: Baffles are arranged at the right angle to the direction of the flow in an overflow section from the upper portion of the upward passage B to a tank 6b to form a zig zag passage F comprising upward and downward stream. The cross-sectin area of the upward stream is made larger than that of the downward stream so that the upward flow of the liquid in the curved passage F moves at a higher velocity than the downward flow thereof. In this manner, the liquid is caused to come into colision with the baffles in such a manner that the bubbles combine together with each other. Accordingly, the bubbles can be enlarged in diameter, eventually led to be broken, ascending away from the liquid while the higher velocity of the upward stream promotes the deairing

Filed: 1982-06-24
Abstract: PURPOSE:To secure a clear broadcast while preventing interference sound between speakers without reducing conventional calling capacity, by employing a system which changes signals in sending order for a selective calling system. CONSTITUTION:Figures I and II show the signal constitution of the conventional system and a figure III shows inverted signal constitution. In the figures, 21, 23 and 21' are calling codes and 22 is a voice signal for announcement. The constitution in the figure I allows the 1st and the 2nd two receiving stations to be called at the same time by a signalcall and the system in the figure II calls the 1st receiving station corresponding a calling code ABV for the 1st time and the 2nd receiving station with a calling code ADE for the 2nd time. The system in the figure III is similar to that in the figure II, but only the constitution of a selective calling number is different. Namely, the system in the figure II requires different calling codes like ABC and ADE and the inverted system in the figure III replaces only the 2nd and the 3rd codes in the calling code with each other lide ABC and ACB, so freqeuncy selecting filters of the same constitution is attached merely in the opposite direction and the combination of the same code is usable.

Title: Automatic focusing device of electronic scan microscope
Inventor: NAMAE TAKAO
IPC: H01J37/21
Filed: 1977-09-12
Abstract: PURPOSE: To secure the use of the automatic focusing device in the optimum state at all times by keeping a constant scanning speed automatically for the period during which the automatic focusing is being given, and thus to enhance the operation performance of the electronic scan microscope.  
     CONSTITUTION: With transmission 15 of the start signal, a constant scanning speed suited to the signal process circuit is given immediately even though speed control circuit 16 may be set to any scanning speed. The start signal is applied to automatic focusing device 14 via delay circuit 17, so a constant scanning speed is set when device 14 is actuated. Thus, a focal correction is given in the optimum state. When the automatic focal adjustment is over, the end signal is given to circuit 16 from device 14 to switch the scanning speed again to that of before application of the start signal. As a result, the operator can perform observation in the optimum state through operation of the automatic focusing device and irrespective of the scanning speed.
