Title: Line driver circuit
Inventor: IIZUKA EIJI
IPC: H04L25/03
Filed: 1990-11-21
Abstract: PURPOSE:To prevent the fluctuation of the pulse width of a pulse outputted to a line by monitoring a signal outputted to the line in order to detect the pulse width, and transmitting a clock signal whose pulse width is controlled to be an optimal value to an encoder based on this detected result. CONSTITUTION:A pulse width detecting circuit 7 detects the pulse width of the pulse outputted through a buffer 8 to the line, and converted it into a signal such as a voltage or a code. A pulse width controlling circuit 6 controls the pulse width of the clock signal from this signal in order to adjust the pulse width of the output of a driver 2 to be the optimal value. An encoder 1 converts the clock signal whose pulse width is controlled, and inputted data into a transmission path code, and outputs it through the driver 2 and an output transformer 3 to the line. Thus, the change of the pulse width of the pulse outputted to the line, due to the duty change of the clock signal, the variation of the driver circuit, and a temperature characteristic or the like, can be reduced.

Title: Recording apparatus for lighting stroke current of steel tower
Inventor: OZAWA ATSUSHI
IPC: H02G7/00
Filed: 1989-12-08
Abstract: PURPOSE:To accurately record single-pole and bipolar lightning stroke currents by mounting a magnetic tape on which an AC signal is recorded to the member of a steel tower so that the length direction thereof becomes almost right-angled. CONSTITUTION:A positive elastic wave signal 21 of about 1 kHz is recorded on a magnetic tape 20. When a lightning stroke current flows along a steel tower 2, a magnetic field is generated around the steel tower 2 and the signal recorded corresponding to the magnitude of a current is demagnetized by this magnetic field. The magnitude I of the lightning stroke current can be calculated on the basis of this demagnetization width W. It is advantageous to arrange a magnetic tape case 4 to the right-angled part of the leg of the steel tower using L-steel from the aspect of workability, stability and current recording sensitivity. When the case 4 is mounted to the end part of L-steel, recording sensitivity can be enhanced.

Title: Photo assisted cvd system
Inventor: SATO JUNICHI
IPC: H01L21/205
Filed: 1988-12-14
Abstract: PURPOSE:To uniformize the thickness and quality of a CVD film without making an apparatus large and complex by a method wherein, while light is projected nearly parallel with a substrate, CVD is progressed and the substrate surface is scanned with the light. CONSTITUTION:A mirror 6, optical system member, is arranged in a reaction chamber 1; a laser beam LB entering through a transparent window 3 on the upper surface 2 of the reaction chamber 1 is reflected by the mirror 6; thus the light parallel to the rear of a semiconductor wafer 7 is obtained. Thereby, the light from an external laser 4 can be projected parallel with the semiconductor wafer surface without increasing the height of the reaction chamber 1. Since the semiconductor wafer is moved by a retaining stand 5, it is not necessary to move the laser 4, so that complicated and large laser transferring mechanism to move the laser 4 is unnecessitated. Since the wafer is moved relatively to the optical system in the reaction chamber 1, the uniformity of film thickness and film quality are improved by scanning the substrate surface with light.
