Title: Leveling plate for cutting
Inventor: KOJO AKIRA
IPC: B25H1/00
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To maintain the quality of a cut material by erecting a plurality of cast iron plates on frames at prescribed spaces apart, placing and supporting the material to be cut, and thereby preventing melt at the time of cutting from sticking to the rear face of the material by the return of a plasma arc or an assist gas, even if a cutting torch is right above the plate. SOLUTION: A plurality of cast iron plates, which are each inserted between a pair of brackets 13 oppositely placed on frames 10, 11, 12, are erected at prescribed spaces apart, to form a level block for cutting in accordance with a moving distance of a plasma cutting device. Since a cast iron plate is easier to melt than a steel plate, these cast iron plates 14 for placing and supporting a material to be cut are likely to melt at the time of cutting; hence, the melt from the cutting is provided with a constant relief, enabling the cut material to retain quality. In addition, being erected, these cast iron plates 14 are less susceptible to erosion in the cutting operation of the material and provided with a comparatively long life. If the cast iron plates become unstable in supporting the material to be cut because of increased erosion, they are easily replaceable.

Abstract: PURPOSE:To enable the formation of excellent blanking line erase pulse, by detecting rapid current or voltage change produced between the feedback period of output and scanning period with the signal path on and after the negative feedback amplifier of the vertical deflection circuit. CONSTITUTION:The inputs v1, v2 of the differential amplifiers Q1, Q2 during scanning period, are almost equal because of negative feedback from the vertical output circuit 3, and all the circuits are operative at active area. At the blanking period, the feedback signal v2 to ramp signal v1 is lower potentially, the differential amplifier is perfectly inverted to turn off the differential amplifier Q2, resulting that the differential amplifiers Q4, Q6 are OFF. The base potential v3 of the differential amplifier Q6 is almost zero during the output blanking period. Accordingly, by detecting the period when this v3 is at 0 level, the blanking erase pulse can be made.

Abstract: PURPOSE: To obtain a delay circuit, which can securely delay a given signal in response to a clock signal by providing a transfer means, which transfers the held data signal from the first holding means to the second holding means, in response to the holding of the second holding means. CONSTITUTION: Since a transistor 1 is turned on in response to the rising of a clock signal CK, an input data signal D is held in the master latch constituted of inverters 2 and 3. A transistor 4 is also turned on in response to the rising of the clock signal CK. Since a transistor 5 is connected between the transistor 4 and a slave latch, however, the timing of the supply of the data signal held in the master latch to the slave latch is controlled by a signal CTI. Therefore, the data signal held in the master latch is imparted to the slave latch through the transistors 4 and 5, in response to the rising of the signal CTI.
