Patent JP-S6119169-A (JP)
Title: Multi-emitter transistor
Inventor: HATANO TSUTOMU
IPC: H01L29/73
Filed: 1984-07-06
Abstract: PURPOSE:To reduce the dispersion of characteristics due to the positions of emitters by increasing the size of emitter regions in succession in response to distances among a base contact and a plurality of emitter contacts. CONSTITUTION:The areas of emitter regions 7a, 8a, 9a in input emitter terminals E1, E2, E3 are augmented in succession in response to distances among a contact 15 for a base terminal B and emitter contacts 17a, 18a, 19a. Transistor currents are in proportioned to junction areas, and are represented by the exponential function of junction voltage, and junction voltage is reduced with the increase of junction areas at fixed currents. Accordingly, junction voltage is minimized with a separation from the base terminal of emitter terminals, and base resistance at a time when voltage at a low level is inputted to the terminal E3 is made larger than that at a time when it is inputted to the emitter terminal E1, while base- emitter voltage is reduced, thus minimizing the dispersion of input currents.

Title: Broad band lan system
Inventor: YAGYU KAZUO
IPC: H04N7/16
Filed: 1986-06-18
Abstract: PURPOSE:To send out an image pick up output to a picture image channel at only a camera connected to an adapter by superposing a camera switching command on the cable of FM/television broadcast and data communication, etc., and operating in a specified mode an adapter between the camera and a transmission line while responding the reception of the command. CONSTITUTION:The adapter 7 consists of a data transmitting/receiving section 10 and a camera signal switch 76. A demultiplexer/multiplexer 71 takes out the outgoing signals for data transmission from input signals from a transmission system and synthesizes incoming signals from a camera and incoming signals for data transmission and sends out to the transmission system. Data (command) from the data terminal of a monitor side are stored in a memory 74 through an RF (radio frequency) MODEM 72 and a communication control processor 73. A local processor 75 controls signal transmission from the camera to the transmission system by analyzing the command in the memory and turning the switch 76 on/off. The RF MODEM 72 executes mutual conversion between high frequency signals and digital signals. Accordingly, the signals from plural cameras can be monitored by an moving image 1 channel by designating a camera from the monitor side terminal.

Abstract: PURPOSE:To increase an S/N ratio with an oscillator of low output, by emitting simultaneously an electromagnetic wave of 2 and more wave length elements including wave length element of, at least, the highest strength among the total electromagnetic wave emitted from laser onto the surface of a sample to be detected. CONSTITUTION:From a laser light oscillator 14b are emitted as outputs, for instance, the total wave lengths from 457.9nm to 514.5nm of the argon laser, and the outputs is projected as a band-shape light emitted area 10a onto a surface of a high-temperature slab 10 from a light-emitting lens system 22 including a cylindrical lens, etc., as a band-shaped light projection part 10a. In the conventional method, the argon lase of 514.5nm single wavelength has been employed as the source and projection of the laser light of approx. 1W at the output end with the conventional apparatus reveals an S/N ratio of flaw signal as approx. 2.5. However, the S/N turns out 4 and above for a source of total wave lengths available for above oscillator. Consequently, the S/N is raised even with an oscillator of a limited output.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject manganese bearing molecular sieve structure and exhibiting high catalytic activity even under highly humid conditions by mixing and reacting a solution of manganese (II) salt(s) with a solution of permanganate(s) in the presence of a soluble titanium salt to effect precipitation. SOLUTION: This manganese is obtained by mixing and reacting a solution of 60 pts.wt. of one or more kinds of manganese(II) compound (e.g. MnSO4 ) with a solution of 40 pts.wt. of one or more kinds of permanganate compound (e.g. KMnO4 ) in the presence of a soluble titanium salt (e.g. titanium chloride) pref. at <=pH 3 and 50-150 deg.C to afford a precipitate as the aimed compound; wherein the titanium content of the final manganese is adjusted so as to be 0.5-50 wt.%. The manganese which contains titanium and has molecular sieve structure, yields synergistic effect owing to a combination of the titanium with the molecular sieve structure, resulting in markedly improvement in its oxidative catalytic activity compared to that exhibited by a manganese alone and suppressing the deterioration of its catalytic activity due to water formed or humidity.

Title: Electricity generation control circuit for internal- combustion engine
Inventor: BITOU HIROMICHI
IPC: F02D29/06
Filed: 1981-09-08
Abstract: PURPOSE:To improve the fuel efficiency of an engine particularly in its light- load operation, by providing a means for detecting the stationary operating condition of the engine and a means for restraining the produced power of an electricity generator under the stationary operating condition. CONSTITUTION:When an electric load 16 is off and a transistor T5 is on and the speed of an engine is nearly constant, a transistor T4 is turned on to connect a resistor R2 in parallel with a voltage dividing resistor R1. As a result, a voltage applied to a Zener diode Dz rises to turn on a transistor T3 and turn off transistors T1, T2 to lower the output voltage of an electricity generator 2. Consequently, the transistor T3 is turned off so that the voltage rises again. The same process is repeated to keep the voltage constant. In that case, the output voltage of the generator 2 is lower than a rated value. While the output voltage is lower than the rated value, a battery 4 is discharged and the restraint of electricity generation is maintained until the terminal voltage of the battery becomes lower than the output voltage of the generator 2.
