IPC: B60T8/26
Filed: 1978-11-23
Abstract: PURPOSE: To provide better proximity against an ideal brake force distribution curve line than a single break point by using a pressure reducer having multiple break points, allowing the first break point to be an operating fluid pressure when a certain deceleration is obtained.  
     CONSTITUTION: On building-up an operating fluid pressure, first piston 10 is displaced to a right direction caused by the force balance between the right-lift area difference and first spring 12 to allow to cut-off a passage 14. Second piston 11 is also displacing to a right direction by the force balance caused by the right area and second spring 13. On reaching a certain deceleration, an inertial body 4 is displaced against a slope to close a valve seat 5 to allow to cut-off the communication between an inlet 2 and an exit 3. Besides, when the operating fluid pressure is increased, the piston 10 is pushed back to the left direction to allow the piston 11 pushed to the right direction to come finally in contact further allowing the additional built-up pressure to displace to the left direction together with the piston 11.

Filed: 1990-06-01
Abstract: PURPOSE:To suppress the ariation of scanning lines due to the variation in the wavelength of a laser beam by providing an actuator which drives a laser beam source uniaxially. CONSTITUTION:The laser beam emitted from a laser beam source 6 passes through a beam splitter 10 and is diffracted by a hologram disk 8 to form its image on a scanned surface. Even if the wavelength of a semiconductor laser is varied, the variation in the subscanning direction is suppressed and the laser 6 is displaced by a laser actuator in a direction different from the optical axis so as to form the image on the scanned surface without fail. Further, the laser beam which is separated by the beam splitter 10 so as to detect the wavelength at all times passes through a diffraction grating 11 for wavelength detection and is made incident on a detector 12. Thus, the actuator which drives the laser beam source uniaxially is provided to suppress the variation of scanning lines due to the variation in the wavelength of the laser beam.

Title: Transformer cooling apparatus
Inventor: FUJIWARA TOSHIHIKO
IPC: H01F27/08
Filed: 1982-08-19
Abstract: PURPOSE:To eliminate the insertion loss of a variable-frequency inverter and contrive an improvement in efficiency, by a method wherein a cooler is driven by the variable-frequency inverter when a transformer is in a light load condition thereby to reduce the auxiliary loss and is directly driven by a commercial frequency power source when the transformer is in a load condition near its rated load. CONSTITUTION:With an electromagnetic contactor 8 opened, electromagnetic contactors 13 and a no-fuse breaker 9 are closed to connect a cooler 2 to a variable-frequency inverter 12. Any change in output frequency of the inverter 12 changes the revolution numbers of oil transfer pump motors 3 and fan motors 4, resulting in changes in oil transfer rate and air-supply rate. Consequently, the cooling capacity and auxiliary loss of the cooler 2 change. On the basis of a signal detected by a detection unit 5, an arithmetic control unit 1 obtains a required cooling capacity in accordance with the load condition of the transformer. The electromagnetic contactors 8 and 13 in combination constitute a selector circuit for selectively changing over between a commercial frequency power source 10 and the variable-frequency inverter 12. When the transformer is in a load condition near its rated load and the insertion loss of the variable- frequency exceeds the auxiliary loss reducing effect offered by the control of revolution number of the cooler, the selector circuit changes over to the commercial frequency power source to drive the transformer directly by the commercial frequency power source.
