Title: Method for continuously and electrolytically cleaning strip
Inventor: FURUYA TAKUMI
IPC: C25F7/00
Filed: 1987-11-26
Abstract: PURPOSE:To prevent the damage of an electrode due to the contact of the electrode with a deformed part of the strip, the shortening of the service life, and the breakage of the strip by making the interval between the electrodes provided in an electrolyte larger than a normal value when the deformed part of the strip passes between the electrodes. CONSTITUTION:When the deformed part of a band steel F such as the welded joint and lug passes through a shape detecting part 10, an abnormality signal is transmitted to a control panel 11 from the detector 10. The time necessary for the band steel F to travel from the detector 10 to the electrodes 5a and 5b is calculated by the control panel 11 from the line speed. A driving command is imparted to an actuator 9 immediately before the deformed part of the band steel F reaches the electrodes 5a and 5b while taking account of the delay actuation time of the actuator 9. As a result, the electrodes 5a and 5b are moved through cross beams 7a and 7b and supporting plates 6a and 6b as shown by the alternate long and two short dashes line in the figure, hence the interval is widened, and the deformed part is passed. When the detection value of the detector 10 returns to an allowable range, a command is transmitted to the actuator 9 from the control panel 11, and the interval between the electrodes 5a and 5b is returned to a specified set dimension.

Title: Driving circuit for end face luminous type led
Inventor: YAMANE KAZUO
IPC: H04B10/564
Filed: 1986-12-15
Abstract: PURPOSE:To effectively protect an end face luminous type LED from the induced emission by supplying the output signal of a comparing circuit, which compares the output signal of a reception light monitor circuit with a reference signal, to a driving control circuit as the signal which cuts off a driving current. CONSTITUTION:If an LED which naturally emits light causes laser light emission, namely, induced emission especially at a low temperature, the quantity of light emitted from the LED 10 is increased. As the result, the voltage value given from a light reception monitor circuit 14 to a comparing circuit 16 exceeds a reference voltage Vref, and a signal of the high level is outputted from the comparing circuit 16. A transistor TR 2 receives this signal and is turned on and supplies a low voltage -V to the anode of a clamping diode D1 to turn off a TR 1, and constant current driving of the LED 10 is stopped. Thus, the LED 10 is protected from element breakdown due to induced emission.
