Title: Frequency detecting circuit
Inventor: KONDO TOMOJI
IPC: G01R23/10
Filed: 1985-05-17
Abstract: PURPOSE:To prevent reverse runaway at the damping time of a motor by using a shift register in a frequency detecting circuit and giving a time hysteresis at the switching time of a frequency detection signal. CONSTITUTION:If one or more leading edges of the output signal of a counter 3 exist between leading edges of the FG signal of an input terminal 2, outputs of D FFs 4-7 are switched to the low level; and if four or more leading edges of the FG signal exist after the trailing of the output signal of the counter 3, the output level of the FF7 is switched to the high level. Consequently, the motor is braked and decelerated while a reverse torque acts upon the motor; and when the FG signal frequency is lower than the output signal of the counter 3, outputs of FFs 4-7 go to the low level and it means the detection of stop of the motor. The motor starts reversing to try to stop by friction after the torque of the motor is zero and since the output level does not go to the high level unless four or more leading edges exist continuously though the FG signal frequency is higher than the output of the counter 3, the motor is stopped by friction.

Title: Method for forming glass pipe
Inventor: IMAMURA HIROSHI
IPC: H01J9/24
Filed: 1984-05-24
Abstract: PURPOSE:To form easily a glass pipe having a noncircular cross-section by putting inner dies in a glass pipe having a circular cross-section, placing a lower die provided with a softening deformation sensor under the glass pipe, heating the whole pipe, and deforming it while monitoring the softening state. CONSTITUTION:A glass pipe 1 is placed in an electric furnace so that it is suspended by an inner die 2. When the inside of the furnace is heated to 635- 685 deg.C which is above the softening point of the pipe 1 by 20-50 deg.C, the pipe 1 begins t soften. As softening proceeds, the lower end of the pipe 1 approaches a small hole 4 in the die 3,and a sensor acts to reduce the internal temp. of the furnace to 435-450 deg.C close to the slow cooling point of the pipe 1. The pipe 1 is then cooled slowly to the strain point (395-420 deg.C) or below, and it is allowed to cool to manufacture a glass pipe 1' having an elliptical cross-section. A low voltage discharge lamp having an elliptical or sectorial cross-section which is desirable in respect of pipe efficiency (the quantity of light emitted per unit input) can be easily manufactured.
