Abstract: PURPOSE:To prevent the internal cracking and component segregation of an ingot and to increase speed by forming sleeve-shaped deep grooves on the end faces in both end parts in the axial direction of a roll along the circumferential edges of the end faces and in the axial direction of the roll. CONSTITUTION:The part of the width L2 in the central part in the body part of a support roll 11 for continuous casting is constituted of a solid circuilar columnar part having rigidity; therefore, if the load by the static pressure of the molten steel of a continuous casting ingot is exerted on said part, said part deflects parabollically peaking at the center of the body part shown by a dotted line and the quantity of deflection is delta2. The parts of respectively width L1 at both ends, on the other hand, are of a hollow cylindrical shape and are of flexible and soft construction; therefore, if the load of the continuous casting ingot is exerted on said parts, the parts deflect in the direction reverse from the case of the solid roll as shown by dotted lines, and the quantity of deflection delta1 is generated at both ends. In other words, the deflections of the roll show the curve of a two crest shape peaking at the central part of the body part and both end parts and it is possible to make the absolute value of the quantity of deflection mush smaller.

Title: Synchronizing pulse generator
Inventor: OOWADANO HIROSHI
IPC: F02P5/155
Filed: 1980-02-27
Abstract: PURPOSE:To smooth the starting and running of an internal combustion engine even when the power source voltage is lowered, by delaying the ignition timing. CONSTITUTION:An ignition pulse is outputted from circuit 3 in rsponse to the timing of the half-wave dropping to zero potential, by applying to clipper transistor T2 a half-wave corresponding to the number of cylinders which is obtained by detecting through diode Dd. When the power supply voltage is lowered, the potential difference between the emitter and the collector of transistor T1 is maintained constant by means of Zener diode DZ, however the electric potential between the base and the collector is lowered. Therefore, the emitter current increases, and the oscillation output increases. The ignition timing delays because the output half- wave from the clipper circuit also increases, and the point of zero electric potential dealys. Thereby, the ignition timing is delayed when the power supply voltage is lowered, thus in accordance with a variation of power source voltage, and starting and running of the internal combustion engine shall be smoothed.

IPC: G01S15/58
Filed: 1989-02-01
Abstract: PURPOSE:To reduce the influence of an external noise and to improve reliability by using periodic pulses with specific width which are the output signal of a periodic pulse generator as a control signal and outputting a high-frequency signal to an ultrasonic transmitter intermittently. CONSTITUTION:The high frequency signal 101 generated by a high frequency generator 1 is converted into an intermittent wave 103 by a gate circuit 3 which uses the periodic pulses 102 generated by the periodic pulse generator 2 as the control signal. When the intermittent wave 103 is applied to the ultrasonic wave transmitter 4, an ultrasonic wave S1 which is sent 4 is an intermittent wave. Consequently, a reflected wave S2 that an ultrasonic wave receiver 5 receives and a received signal 104 which is converted into an electric signal are intermittent waves. The pulses 102 are delayed by a delay circuit 5 by the time of the reception 5 of the ultrasonic wave S1 after reflection and the delayed periodic pulses 105 are used as the control signal to control the conduc tion of the signal 104 by a gate circuit 7, so that an electric signal 106 is input ted to a mixer 9 only when the signal 104 which is an intermittent wave is inputted. Therefore, noises which are inputted while the signal 104 is absence are cut.
