Patent JP-S574187-A (JP)
Title: Semiconductor laser device
Inventor: KAZUMURA MASARU
IPC: H01S5/00
Filed: 1980-06-09
Abstract: PURPOSE:To match a grating constant, and to lengthen the life of the device by a method wherein double hetero structure is formed by an active layer by AlxGa1-x AsyP1-y and a clad layer on a GaAs substrate, and the ratios of mixed crystals x, y are selected according to predetermined manners. CONSTITUTION:Stress due to the mismatch of the grating constant increases in the active layer with short wavlengths in the GaAs-Ga1-xAlxAs group double hetero structure, and the life is shortened. Compressive stress increases extremely when the ratio of the mixed crystal x is 0.1 or higher. Accordingly, a range of x=0.07-0.45 and y=0.92-0.99 is used as the active layer and a range of x= 0.15-0.95 and y=0.90-0.98 as the clad layer, and x and y are selected from relationship with a band gap. According to this constitution, stress applied to the active layer of a double hetero epitaxial crystal is reduced remarkably in an extent which cannot be measured, a long life can be attained, the device oscillates in the low threshold and even 700nm wavelength can be obtained.

Title: Amplifier
Inventor: KAWAMURA MASAAKI
IPC: H01L33/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an amplifier which enables temperature compensation without changing electric properties. SOLUTION: When a high-frequency input signal is inputted, the direct current is cut at a capacitor C11 and the input signal is inputted to a gate of a gallium arsenide field-effect transistor Q11. The gallium arsenide field-effect transistor Q11 controls the drain current and amplifies the input signal, and the signal is outputted from a high-frequency output terminal via a capacitor C13. A temperature sensor 11 detects the temperature of the gallium arsenide field-effect transistor Q11 itself or the temperature on the periphery thereof. A current is supplied to a light-emitting diode LED so as to increase the current of a current control circuit 12 along with the rise in temperature, thus controlling the emission intensity. A channel of the gallium arsenide field-effect transistor Q11 is irradiated with a light.  A gain reduced by the rise in temperature is increased by irradiating the channel with a light, thus performing temperature compensation.

Title: Serial communication equipment
Inventor: USHIO YUKIHIDE
IPC: H04B10/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To use a general low-cost infrared ray LED by giving a serial communication request signal to a CPU when it is recognized that a state of input information is subject to change. SOLUTION: Even when no update is found out in output data from a CPU 3, when even one of plural input data given to an electric printed circuit board unit 2 has a change, EXOR circuits 39-43 compare input output states of latch circuits to confirm detection of a state change. Even when there is any state change even in one of the plural EXOR circuits 39-43, a multi-input OR circuit 44 recognizes a state change to provide a communication request signal to the CPU 3. That is, only when re-communication is required due to a communication error, serial communication is executed. Thus, number of times of execution of the serial communication is minimized, and in the case of executing optical communication especially, a general low-cost infrared ray LED is employed for the purpose.

Title: Method for controlling coating weight of hot dip coating and device therefor
Inventor: KURAI MASATOSHI
IPC: C23C2/14
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy and responsiveness in the control of a coating weight for hot dip metal coating. SOLUTION: An operation table indicating the corresponding relation between the coating weight of the coating metal sticking to a steel strip 7 and the injection pressure of the gas injected from nozzles 6 is stored in a mamory 18a. A first arithmetic and logic unit 18 computes the actual coating weight in response with the output of a coating weight meter 13 and executes the computation relating to the corresponding relation in response with the output of a command CPU 16 which emits a production command. The correction coefft. for correcting the injection pressure is stored in a memory 19a. A second arithmetic and logic unit 19 outputs a correction pressure by executing the computation relating to the correction.  A control CPU 17 transmits a control signal to a pressure regulator valve 14 in such a manner that the detected pressure of a pressure gage 15 attains the correction pressure in response with each output. The injection pressure obtd. from the operation table is corrected by the correction coefft. and since the control of the injection pressure is executed in accordance with the corrected injection pressure, the actual coating weight and the target coating weight may be made coincident with each other with good accuracy.

Title: Ultrasonic snowfall sensor
Inventor: SATOU TSUTOMU
IPC: G01W1/14
Filed: 1979-06-21
Abstract: PURPOSE:To detect the surface of snow securely by making a reflective surface of a substance that has higher reflectivity of an ultrasonic wave than that of snow and then by comparing a reflection level in snowfall to that of the reflective surface as a reference level. CONSTITUTION:Detection surface 3 is made of concret, asphalt, etc., high in ultrasonic reflection coefficient and its reflection level is adjusted by gain control part 35 with the output of detector 23 set to level A, thereby regarding level A as 100% reflectivity. Comparison reference setting part 26 generates the value of level AXalpha(alpha=0.8-0.7), which is input to one input terminal of comparator 24. When  a snowfall is zero, comparator 24 receives a greater reflection input than level B and sends out to output 201 a signal changing from ''H'' to ''L'' and when snow falls, no greater signal than level B is input, so that output 201 will be at ''H'' at any time. Therefore, the output of comparator 24 is considered a reflection output to find the relation to a transmitted wave from head 21 to the reflective surface, so that the snowfall can securely be detected.

Title: Gas cut-off valve
Inventor: TOMOE SHINJI
IPC: F16K31/06
Filed: 1986-04-04
Abstract: PURPOSE:To reduce operating power of a cut-off valve, by preventing that the sliding resistance of an O-ring of a gas sealing means is badly influenced by operating power, when the cut-off valve is closed. CONSTITUTION:A contacting joint between the first plunger 6 and the second plunger 5 is tight, and these plungers 6, 5 are attracted with each other, by operation of magnetic line of force of a permanent magnet 1. When an excitation current is sent to a coil 12 by valve closing signal, the magnetic line of force at the joint between both plungers 5, 6 is weakened, and a valve disk 8 is closed by a spring 9. Then, the magnetic line of force of the permanent magnet 1 acts on the contacting joint between both plungers 5, 6, and both plungers 5, 6 are attracted with each other. As only the second plunger 5 is formed with gas seals 15, 18, small operating power is enough to drive the cut-off valve.
