Title: Drilling and cutting method and cutting device
Inventor: MEGURO HISAO
IPC: B23K26/142
Filed: 1988-09-28
Abstract: PURPOSE:To splash slag and to maintain a quality state by injecting pressurizing fluid to a drilling position and executing drilling by irradiation of a laser beam and injection of a low-level assist gas and changing the assist gas to a high level after the drilling, then stopping the pressurizing fluid. CONSTITUTION:The pressurizing fluid is injected from a nozzle 9 toward the drilling position of a metallic plate A; thereafter, the drilling is started by irradiating the drilling position with the laser beam and injecting the assist gas of the Lo level along the beam. The slag is blown off by the pressurizing fluid and the sticking of the slag to the tip is obviated. The assist gas is changed to the Hi level and the injection of the pressurizing fluid is stopped, following which cutting is started when a through-hole is formed in the metallic plate. Since the slag does not stick to the tip, the tip is used as a sensor to detect the electrostatic capacity between the tip and the metallic plate and the height of the tip is adjusted and is set in a specified range. The cut surface is maintained at the specified quality in this way.

Abstract: PURPOSE:To improve the quality of a reduced picture by providing a low-pass filter at the input side of a variable magnification processing part, and removing the component of high spatial frequency of picture data before reducing magnification variation is performed. CONSTITUTION:When the signal of reduction is inputted from a CPU 100, the picture data is passed through this circuit by an AND circuit 101.

Then, before the reduction is performed, the high spatial frequency component of the picture data is removed by making it pass through the low-pass filter of a ROM 16 to store eight kinds, for instance, of filter factors so that reflected distortion does not occur at the time of sampling. Thus, the quality of the reduced picture at the time of the reduction variation can be improved.

Title: Variable gain circuit
Inventor: NAKAMURA TOORU
IPC: H03G3/10
Filed: 1983-12-21
Abstract: PURPOSE:To control the change of a working point of a transistor due to the gain variation to the minimum level by providing the variable current sources at both inflow and outflow sides to supply a current to a diode having its variable working resistance connected to the bases of paired differential transistors. CONSTITUTION:The input signals impressed to the bases of buffer amplifying transistors (TR) Q3 and Q4 are supplied to the bases of differential TRs Q1 and Q2 via resistances R1 and R2 respectively. Diodes D1 and D2 having variable working resistances are connected to the bases of the TRs Q1 and Q2, and the emitters of these TRs are connected in common to a constant current source I1. Variable current sources I3 and I4 are connected to the anodes of diodes D1 and D2 respectively, and the cathodes of these diodes are connected in common to a variable source I2. The amount of currents flowing to both D1 and D2 are set equal to each other at 1/2 current of the source I2. As a result, a current which changes the gain is not virtually supplied to resistances R1 and R2. Thus the base working points of both TRs Q1 and Q2 have no variation to produce the margin for setting a DC bias setting. In this way, the highly effective use of the power supply voltage is ensured.

Title: Rope for shock absorbing fence
Inventor: YOSHIDA HIROSHI
IPC: E01F15/06
Filed: 1993-09-02
Abstract: PURPOSE:To obtain a rope for shock-absorbing fence having a stable sliding resistance which can be simply processed, by weaving additionally a reinforcing wire into a spiral groove continuously formed between respective bundles of strands. CONSTITUTION:A plurality of bundles of strands 2 (usually three bundles) are twined. A reinforcing wire 3 is additionally woven in the spiral groove continuously formed between resprective bundles of strands to obtain a rope 1 for shock-absorbing fence. This rope for shock-absorbing fence is laterally laid across posts erected at every specified interval. When the shock-absorbing rope 1 has received an impulse, the impulse is absorbed by the rope while making the rope slide. At that time, the reinforcing wire 3 prevents respective strands 2 from deforming flat or slipping off. In this way, since the section of rope forms an even circular at all positions by the reinforcing wire 3, a stable sliding resistance can be obtained.

Title: Optical bidirectional transmission system
Inventor: SOMA MASAHIRO
IPC: H04B3/46
Filed: 1990-09-12
Abstract: PURPOSE:To immediately detect the disconnection fault of an optical cable by modulating the pulse amplitude of a service data to a main data by a modulating means while using carrier frequencies respectively different on the side of transmission and reception, monitoring and detecting this modulation by a demodulating means at a counter station. CONSTITUTION:When the optical cable connecting counter stations is disconnected, an optical signal (a) is passed through a directional coupler 3 reached to the cut face of an optical cable 11, reflected and reached again through the directional coupler 3 to a demodulator 5 of a reception part 2. At such a time, since the optical cable 11 is disconnected, an optical signal (b), which pulse amplitude is modulated by a carrier frequency f2 from the counter station, does not arrive at the demodulator 5. Since the demodulator 5 is set to the carrier frequency f2 and a demodulator 10 is set to a carrier frequency f1, the service data in the optical signal (a), which pulse amplitude is modulated by the carrier frequency f1, is not demodulated by the demodulator 5, and the optical signal (b) can not be received, either. Thus, the disconnection of the optical cable can be recognized.
