IPC: F02B3/06
Filed: 1993-09-10
Abstract: PURPOSE:To prevent an engine from stopping by reducing a load, when it is charged, so as to lessen decreases in rotational speed (frequency). CONSTITUTION:In an automatic voltage regulator provided with a voltage control amplifier of outputting a control signal for controlling a field current of a generator 1 by amplifying a deviation signal between detection voltage VDET and reference voltage Vs, an FV limiter 15, outputting a limiter signal VFVL added to the deviation signal when decreased frequency voltage with a frequency voltage action frequency lower than an ordinary frequency of a generating set further set sufficiently adjacent to the ordinary frequency and in proportion to an input generator frequency, is provided. When a load is inputted, a generator frequency is decreased to output the limiter signal VFVL from the limiter 15, so that an output of the voltage control amplifier 16 is increased to decrease the field current, and generator voltage is decreased to reduce the load.

Title: Detection method for root gap
Inventor: SUGITANI YUJI
IPC: B23K9/095
Filed: 1986-09-26
Abstract: PURPOSE:To improve a welding quality by dividing the waveform of an arc voltage or that of a welding current at a fixed angle at the front and rear part points in the welding progressing direction and detecting the root gap based on the variation in the difference of the areas formed by each waveform. CONSTITUTION:The rotary welding of a wire 6 is performed by rotating an electrode nozzle 5 in a fillet welding of a lower plate 1 and vertical plate 2. In this case, the arc voltage waveform is divided in the right and left of the welding direction at the constant angle phi0<=+ or -90 deg. respectively with the front point Cf and rear point Cr as the center and the areas Scf, Scr of the waveform between the angle + or -phi0 are found. Since the variation from the reference value of the difference in these both areas has a close correlative relation with the root gap, the root gap and its variation can be detected with a non-contact and at real time by detecting the fluctuation value of the difference in both areas. Consequently the welding control is always optimized and welding quality can be improved.

Title: Apparatus for detecting presence of absence of body to be detected
Inventor: TAKEISHI SHINZO
IPC: H01L31/12
Filed: 1988-09-09
Abstract: PURPOSE:To prevent erroneous operation due to chattering without addition of a special circuit such as a Schmitt trigger circuit by coupling the current input side of a photodetector to the current output side of a light emitting element. CONSTITUTION:A collector which is the current input side of a phototransistor 3 is coupled to a cathode which is the current output side of a light emitting diode 1. When a body to be detected 8 is located at a position shown by a continuous line, light 4 which is emitted from the light emitting diode 1 is all inputted into the phototransistor 3. Therefore, a current Iq which can turn ON an output transistor 6 is flowing through the phototransistor 3. Hence, the detected output at an output terminal 7 is at a low level. When the body to be detected 8 is located at a position shown by a chain line, the light 4 emitted from the light emitting diode 1 is completely shielded with the body to be detected 8. Therefore, the detected output at the output terminal 7 is at a high level.

Title: Refrigerator
Inventor: KARAKAMI TOSHIO
IPC: F25B1/00
Filed: 1988-09-12
Abstract: PURPOSE:To improve stability for a load variation by providing two expansion valves having different capacities and switching a stationary expansion valve according to the magnitude of a load. CONSTITUTION:A solenoid valve 14a is opened in a maximum load state, and an expansion valve 3a is operated. If a load decreases in this state, gas refrigerant to a compressor 1 is slightly liquefied, Thus, the temperature of the inlet pipe of the compressor is lowered. A temperature detector 10 attached to the inlet pipe of the compressor detects it, and a switching unit 15 compares it with a set temperature. If it is lower than the set temperature, the valve 14a is closed, a solenoid valve 14b is opened, and an expansion valve 3b is operated. Since the valve 3b has a small capacity, it reduces a refrigerant amount in a refrigerating cycle to prevent the liquid refrigerant from flowing to the compressor. If a load is increased in this state, it is operated vice versa. If the detected temperature of the detector 10 is higher than the set temperature, the valve 3a is operated, and the valve 3b is stopped.
