Title: Control circuit for ac power semiconductor switch device
Inventor: MIURA SHIYUNJI
IPC: H02M1/08
Filed: 1977-12-23
Abstract: PURPOSE: To smiplify the constitution of the semiconductor switch device control circuit, by using the negative resistance element which flows current at the applied voltage lower than a value and does not flow current at the greater voltage than a value.  
     CONSTITUTION: When AC voltage is fed between the terminals AC1 and AC2, the voltage rectified with the diodes D2 to D5 is fed to the negative resistance element A via the photo variable resistance element PC. Further, the element A consists of the n channel FET1 and p channel FET2, and it is conductive when the voltage fed between the terminals AC1 and AC2 is low and not conductive when it is high, operating as the detection element near the zero potential of AC voltage. When the LED photo-coupled with the element PC is illuminated, the element PC is lower in resistance, and the element A is operated, and one of the SCR's with the gate G1 or G2 of SCRGR1 and FR2 in anti-parallel connection. Accordingly, current flows to the load connected between the terminals AC1 and AC2. Thus, the control circuit of a simple circuit constitution can be obtained.

Abstract: PURPOSE:To detect even the motion of a color signal in prescribed or higher frequencies by the sum in one frame of the color signal due to inter-line separation using correlation detection. CONSTITUTION:The composite video signal inputted from an input terminal 101 is supplied to a correlation detecting circuit 116 through a BPF 113. The circuit 116 detects the degree of color correlations between the signal delayed by 1H and 2H through line memories 114 and 115 and the output signal of the BPF 113 and converts it to a coefficient beta, A control circuit 118 outputs a color signal CL' for moving picture through subtractors 119 and 120 and a multiplying circuit 121.

Title: Volume control mechanism for internal announcing device for railroad vehicle or the like
Inventor: NISHIYAMA TOYOO
IPC: H03G3/32
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To improve follow-up of announcing sound volume because of a difference in the voice volume caused by the personal difference of crews by controlling the amplifier so as to fix a ratio between a noise level in a vehicle and an announcement sound level in a car provided with a microphone arranged in each vehicle. SOLUTION: The amplifier is controlled so as to fix the ratio between the noise level in the vehicle and the announcement sound level in the car provided with a microphone 1. Concerning such a volume control, when there is a signal, the voice signal is switched to a sample/hold circuit 13 for announcing and sampled/held. When there is no signal, on the other hand, the voice signal is switched to a sample/hold circuit 14 for noise and sampled/held. As a result, a subtraction circuit 15 extracts a difference between both held signals so that only the signal output of the voice can be provided. Corresponding to this signal, the resistance of a volume control element is changed and the gain of the device can be varied.

Abstract: PURPOSE:To prevent a drop in contrast, which is caused by repeating reflection between a glass plate and detection elements when a micropattern is detected by providing a light transmitting member for hermetically sealing a package storing light detection elements with a coating layer preventing the reflection of light. CONSTITUTION:A substrate 20 is stored in the package, and a window reflecting light is hermetically sealed by the glass plate 24, for instance, being a light transmitting member. The glass plate 24 is provided with the coating layer 33 to prevent the reflection of light. Fluorinated magnesium is used for a coating material. With such single coating layer, the reflectance of the glass plate 24 is about 3% including both surfaces. As for multilayers, the reflectance is reduced to about 1%. Incident eight with an angle theta is reflected on the surface of a conductor 23. However, the light towards the glass plate 24 through an optical path 28-1 is hardly reflected on the lower surface of the glass plate because of the coating layer 33 on the glass plate 24, and transmits the glass plate 24 to the outside. As a result the light making incident on the detection element 26 is only direct light as an optical path 27 shows.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To detect an abnormal operation of a printing means, e.g. repetition of printing operations irrespective of print data at an early stage and automatically stop the printing means. SOLUTION: A laser beam printer sets a required count of print pages added to a header information from a host computer, thereby carrying out a printing process (steps S13, 14). Then, an output count of recording papers is counted on the basis of a detection signal of a paper output sensor, and whether or not the counted value (present output count) is larger than the set value (required count of print pages) is detected. When the counted value exceeds the set value, a printing part is judged to go out of control by some reason and operate abnormally, whereby the printing process is stopped to forcibly stop the operation of the printing part (steps S15, 16, 19).

Title: Control device for bubbly stream generator
Inventor: SONEDAKA KAZUNORI
IPC: F24H1/00
Filed: 1992-06-16
Abstract: PURPOSE:To enable the device to rise quickly at the time of restarting operation by stopping a pump to pressurize water after a specified period of time has passed sine the stoppage of an air intake device which introduces the air to be dissolved into water. CONSTITUTION:Water is circulated in a circulating circuit A by a pump 5, and the water is discharged to a water tank 1 from a feeding pipe 3. An ejector unit 8 introduces the air from an air intake device 15 and the water from the water tank 1 through a returning pipe 17 to the circulating circuit A. For this reason, the air is pressure-dissolved into the water, and the water is discharged to the water tank 1 from the feeding pipe 3 while the pressure is reduced, and a bubbly water stream is generated. When the operation to generate the bubbly water stream is stopped, the pressure of the pressurizing passage inclding the pump 5 is reduced, and the air dissolved in the water is re-gasified, and resides in the passage. Then, a control means 18 stops the pump 5 only by delaying the timing by a specified period of time than the timing of the air intake device 15 when the operation is stopped. Thus, the water in which the air is dissolved is discharged to the water tank 1 by the pump 5 while preventing air from entering. By this method, an air biting of the pump at the next operation is reduced.

Title: Motor controller
Inventor: HAYASHI TOMOHISA
IPC: H02P29/00
Filed: 1985-07-16
Abstract: PURPOSE:To prevent a controller from erroneously operating owing to a noise by providing electric insulating means in a passage of a sensor signal. CONSTITUTION:A PWM signal generator 2 which receives the signal of a controller 1 supplies a PWM signal to a power unit 3, but since it is electrically insulated by a photocoupler 12A during this period, a switching noise generated when a power element is switched by the power unit 3 is not transmitted to the generator 2 and the controller 1. Since a sensor 5 mounted on a motor 4 and the controller 1 are electrically insulated from each other by a photocoupler 12B, only a signal component is transmitted to the controller 1. Thus, it can prevent the invasion of a noise from erroneously operating this device.
