Title: Control of inverter
Inventor: OGAWA KIYOSHI
IPC: H02M5/45
Filed: 1978-05-30
Abstract: PURPOSE: To compensate the delay of chopper circuit control by adding a controllable function at transient time to power inverter.  
     CONSTITUTION: The main circuit consists of the rectifier 5, the DC filter circuit 2, the chopper circuit 6, the DC filter circuit 7, the inverter 3, and the output transformer 4. In the steady state, the chopper 6 is controlled by the phase signal 16 from the amplification by the error amplifier 15 of the deviation between the output of the output voltage detector 14 and the voltage reference value so as to keep the output voltage constant. In the transient time, e.g., the abrupt change in load, etc., the error amplifier 25 is operated to dispatch the output phase control signal 26 by which the power inverter 3 is operated to control output voltage temporally, displace it with control system for the chopper circuit 6 after 2 to 3 cycles, and transfer it to the transient time control system with the chopper circuit 6 again. Thus, it is possible to prevent the variation in output voltage at transient time due to the response delay of DC controller.

Title: Light-applied vibration sensor
Inventor: HOSOE KATSUHIRO
IPC: G01H9/00
Filed: 1984-03-31
Abstract: PURPOSE:To make it possible to detect even minute vibration including high frequency vibration highly sensitively and to make the entire structure compact, by utilizing the bending resonation of a vibrator. CONSTITUTION:A vibration sensor is constituted by the following parts: a light sending optical fiber 3, a light receiving optical fiber 5, a reflecting surface 17 and a vibrator 15, whose one end is attached to a wave receiving surface 13 of vibration and other end supports the reflecting surface 17. When the wave receiving surface 13 does not receive the vibration, most of the light emitted from the light sending optical fiber 3 is inputted to the light receiving optical fiber 5. When the wave receiving surface 13 receives the vibration, the vibration having the large amplitude is yielded in the vicinity of the natural vibration frequency of the vibrator 15. The reflecting plate 17 is vibrated at the large amplitude. As a result, the amount of the light, which is inputted to the light receiving optical fiber 5, is changed. The vibration amplitude of the reflecting plate 17 is proportional to the strength of the vibration. The amount of the light inputted to the light receiving optical fiber 5 depends on the magnitude of the vibration amplitude of the reflecting plate. Therefore, the strength of the vibration can be detected based on the amount of the received light.

Title: Roll for counter measure against higher temperature of continuous casting
Inventor: YAMAGAMI YOSHIAKI
IPC: F16C13/00
Filed: 1979-05-24
Abstract: PURPOSE:To use heat-resisting steel only in the required places and achieve the reduction of heat transfer from the continuously cast product to the roll by winding the wires made of heat-resisting steel on the portions of the roll shaft having a cooling water hole at the shaft center part in contact with the product being produced continuously thereby protecting the roll surface by the heat-resisting steel. CONSTITUTION:A wire-stopping protrusion 6 is provided at one end of the roll shaft 10 provided with a cooling water hole 1 at the axial center 9 and the wires 5 made of heat-resisting steel (for example, 25Cr-20Ni) are wound on the roll shaft 10 to externally envelope the same. The entire roll shaft surface in contact with the continuously cast produce 11 is wound by these wires 5. A wire-stopping sleeve 7 made of ordinary steel is welded and fixed 4 to the other end of the roll shaft 10 to prevent the deviation and loosening of the coiled wires 5. This method averts the reduction in the roll diameter owing to roll fracture and oxidation required as a continuously cast roll C and even if inexpensive ordinary steel is used for the roll shaft 10, the roll shaft is able to provide its function sufficiently because the heat transfer to the roll C is less.
