Title: Method of and apparatus for controlling motor operation
Inventor: FUJIWARA MASATAKA
IPC: H02P7/292
Filed: 1979-03-30
Abstract: PURPOSE:To improve the controlling performance of a mechanical equipment for intermittent load operation by switching to current minor control from the speed feedback control by detecting the load application starting point with a position detector mounted to the machine side whenever the load suddenly changes. CONSTITUTION:The limit switch 12 mounted to an intermittent load 11 including a press machine is so arranged that the press starting point is mechanically detected and receiving the detection output through a cable 14, FF16 produces the output of ON until the limitting switch 13 begins to work from the action of the switch 12 at the time of pressing. By the output signal of the FF16, the FET 17 is turned on during the pressurization to apply a given constant potenial to the current controlling amplifier 4, whose output is applied to the thyrister stack 6 during the pressurization through a phase control circuit 5 to fire the element whereby the DC motor 7 is accelerated with the output voltage. By this, the controlling performance of the mechanical device subject to intermittent load at a fixed cycle can be improved along with the higher safety and the workability.

Title: Semiconductor switch unit
Inventor: UCHIDA RIYOUHEI
IPC: H03K17/732
Filed: 1978-03-29
Abstract: PURPOSE:To reduce the loss of commutaion transistor and diode and to simplify the switch and to make small the unit in size, by performing sure commutation through the suppression of the collector current of commutation transistor to slightly greater value than the load current. CONSTITUTION:When switch-on is made by giving the drive signal Sg to the auxiliary transistor QC, the voltage of the control power supply Vc is fed to the winding N12 wound on the core T1. The winding N11 voltage induced feeds the base current iB limited with the resistor R for commutation QM. When QM is turned on, the voltage induced on the winding N21 wound on the core T2 is approximately zero and the voltage induced on the winding N10 wound on the core T1 gives the back bias voltage to the thyristor CR via QM turned on. As a result, the current flowing to CR starts commutation to QM and the rapid increase in the collector current of QM is restricted with the inductance component of the circuit.

IPC: G07G1/01
Filed: 1979-03-28
Abstract: PURPOSE:To make adjustment possible easily independently of the amplification charactertistic of a tape deck, by measuring the time width of a shaped pulse waveform in the cash register side to decide and display whether the reproducing level in the tape deck side is proper or not. CONSTITUTION:The deck side signal is caused to pass through cable 5 and is amplified by amplifier 7 of electronic apparatus 3 and is rectified and integrated by integrating equipment 8, thereby obtaining a square wave in waveform shaping circuit 9. The pulse time width of this wave is measured by measuring circuit 10. Decision circuit 11 compares time width T of the measured pulse with a set value and outputs true value 1 and true value 1 to output end d1 and output end d2 respectively for larger time width T and smaller time width T respectively. Signal H passes through AND gate 14 to display signal H indicating an excessive level on display part 16, and signal e2 at output end d2 passes through AND gate 15 to display M indicating a proper level on display part 16. Reproducing level detection circuit 17 detects a level lower than a prescribed value to inhibit the operation of circuit 11, and simultaneously, circuit 17 sends a signal indicating a too-small level through AND gate 19 to display L on the display part.

Title: Method of and apparatus for measuring sun shade time
Inventor: TSUJI HIROSHI
IPC: G04F13/00
Filed: 1979-03-31
Abstract: PURPOSE: To accomplish accurate and quick measurement of sun shade time by indicating the position in the solar direction line so as to be proportional to the interval of solar time.  
     CONSTITUTION: 11P and 10P are solar direction lines at the sun shade measuring time. LSP11, LSP10 and the like are azimuths determined from the latitude, solar declination and time interval at the point P of measuring sun shade time. When the center of the eccentric circle curve is expressed by Q, PQ=M. The radius of the circle is expressed by L. In this case, there is no proportional relationship between the azimuth and the time interval. for example, when the measurement is made in the direction from 12 to 8, the increment of the azimuth is lessened, as the time interval increases. However, if L and M are established to make the length of each circular arc of the eccentric circle equal when the circle is cut by the solar direction line, every angle of the center becomes equal with the center Q as the vertex, thus proportional to the time interval. Therefore, the relation is determined between the time interval and the time scale indicating angle at the center Q by choosing a proper ratio of M/L and then, the ratio is corrected by the result. By this, each angle of the center with the center Q as the vertex can be determined at a correct proportion.

Abstract: PURPOSE:To display the amount of water in a container stably and accurately even though the conditions in the container are fluctuated to a large extent, by always supplying cooling water from the lower parts of a pressure difference pipe, which communicates the container with a reference level device, so that the temperature of the water in the differential pipes and the reference level device does not exceed a boiling point. CONSTITUTION:The reference level device 1 is communicated to the container 3 by the pressure difference pipes 2A and 2B. A differential pressure gage 4 is provided in the middle of the pressure difference pipe 2B. A cooling water supply pipe 8 is connected to the pressure difference pipe 2B on both sides of the differential pressure gage 4. A cooling water pump 9 is connected to the cooling water pipe 8.

Thus the temperature of the a water in the reference level device 1 and the container 3 can be maintained at the low value. Even though the pressure in the container 3 is decreased to an atmospheric pressure, possibility of boiling is completely eliminated.

Title: Exhaust diffuser
Inventor: AOKI SUNAO
IPC: F01D25/30
Filed: 1993-02-26
Abstract: PURPOSE:To reduce the generation of exhaust noise and reduce the length of an exhaust gas duct by a method wherein a sound absorbing material is mounted in a stretched state on the outer periphery of a strut arranged in a state that it is spread toward a downstream and protruded toward the inner surface of an outer cylinder, through which exhaust gas flows, to support an inner cylinder. CONSTITUTION:In an exhaust diffuser 1, a plurality of struts 2 to support an inner cylinder 4 are disposed such that the strut is formed with front side rear so that peeling is prevented from occurring owing to back wash. A sound absorbing material 3 is mounted in a stretched state to the strut 2 and additionally functioned as a muffler for exhaust gas. The flow of exhaust gas is impeded by the sound absorbing material 3 of the strut 2 and accelerated. By utilizing the acceleration, the outer periphery of an exhaust gas diffuser 1 is spread to a maximum of 30-40 deg. in a range wide enough to prevent the occurrence of peeling and the area of a flow passage is sufficiently ensured without being ensured. Since, as noted above, the length of an exhaust duct 6 is decreased, a space for equipment and the cost are reduced and noise of a low frequency is prevented from being generated.
