Title: Discharge lamp high frequency lighting circuit
Inventor: BERGERVOET JOZEF REINERUS M
IPC: H02M1/00
Filed: 1993-11-24
Abstract: PURPOSE: To reduce a quantity of generated disturbance by means of such sequential processes as jointing one end of the second branch passage to a DC-AC converter, the other end thereof to a rectifying means, the second branch passage is made conductive to both alternate currents and jointing the other end to an input terminal. CONSTITUTION: The first branch passage is composed of a capacitor 16, and the second branch passage is composed of a capacitor 22. When terminals 1, 2 are connected to a voltage source, current rectification is carried out by means of a diode bridge G and DC voltage is generated across the both ends of the capacitor 16. Simultaneously, a control circuit S sets switching element 18, 19 alternately conductive and non- conductive at a high frequency. Resultantly, high frequency current flows and a high frequency voltage is generated at a common jointing point to a capacitor 36 and a discharge lamp 20.  Since this common jointing point is connected to the terminal 2 via a capacitor 22, during the period of time when the instantaneous amplitude of a low frequency power supply voltage becomes lower than a voltage between both ends of capacitor 16, a low frequency voltage source comes in its state to generate electric current. This fact stands for reduction of the quantity of disturbance generated from the circuit.

IPC: H01L21/8238
Filed: 1989-11-10
Abstract: PURPOSE:To prevent malfunction due to effect of ground level noise by devising the device such that the ground level noise gives an effect on one N-channel MOS TR and other P-channel MOS TR of a couple of CMOS inverters simultaneously so as to reduce the mutual conductance of them. CONSTITUTION:When noise is generated in ground level, a mutual conductance of an N-channel MOS TR Q2 at an inverter 2 receiving a logic input A is decreased similarly in the case of a conventional device to increase a level of a logic output B, and a mutual conductance of a P-channel MOS TR Q3 at an inverter 3 receiving a logic input A' is decreased to decrease a level of a logic output B on the other hand. Thus, a level change in the logic output B in total is suppressed small. Then the disturbance on the circuit operation due to fluctuation of a ground level due to noise is avoided.

IPC: B21B15/00
Filed: 1990-11-01
Abstract: PURPOSE:To make the travelling speed of a cutting device for band steel travelling at high speed high-speedy to improve productivity by cutting band steel by tensile force given to the band steel between upper and lower pinch rolls and the shearing force of upper and lower knives on the outer peripheries of drum shears for band steel travelling at high speed when a band steel coil attains fixed weight. CONSTITUTION:When a band steel coil Sc has attained fixed weight, the upper and lower drums 11,12 and upper and lower knives 13,14 of drum shears 4 for band steel travelling at high speed are rotated at, for instance, the peripheral speed of the maximum 500m/min at the time of cutting process. The band steel S is cut by the shearing force caused by fly wheel effect of the upper and lower knives, tensile force generated between an outside pinch roll 5 and an inside pinch roll 5 by slight increase in the number of rotations of the outside pinch roll 5, and tension caused by knife peripheral speed at the beginning of cutting process slower than the travelling speed of the band steel S. In order to prevent the rupture of the band steel S caused by increase in the tensile force between the outside and inside pinch rolls 5,7 at cutting time, the rotation of the pinch roll 7 in front of a coiler is slightly lowered to loose the tension of the band steel S between the pinch rolls 5, 7.
