IPC: B05D3/12
Filed: 1981-09-17
Abstract: PURPOSE:To decrease the number of working stages for producing a pattern considerably by combining the working stages for producing the patterns with printing techniques by hot stamping and thermosetting paints. CONSTITUTION:After the surface of a metallic body S formed to a desired shape by pressing 1 is buffed 2, the surface is roughened to a rough surface by alkali roughening 3.

Before the paint film T formed by said painting cures, a pattern M1 is formed by a hot stamping stage 5, and finally the entire part is baked 6, whereby the decorating is completed. In other words, the products can be perfected with a much smaller number of working stages as compared to the prior art and since the operations of the respective working stages per se are simple, the entire part of the work is simplified and the wasteful consumption of costly materials forming the pattern M1 is obviated. Further, the products having high abrasion resistance are obtained despite the utilization of hot stamping.

Title: Fm demodulation circuit
Inventor: GOTO MASAHIRO
IPC: H03D3/00
Filed: 1984-07-13
Abstract: PURPOSE:To make the demodulation amplitude level constant without requiring high stability for a monostable multivibrator by adding a pulse width control circuit to an FM modulation circuit using zero cross detection. CONSTITUTION:A DC component 16 of a demodulation LPF2 is detected by a DC component extracting circuit 11. A threshold value voltage generating circuit 12 generates a threshold voltage of a comparator 10 based on the DC component 16. A pulse train 4 generated by a monostable multivibrator 1 becomes a pulse train 13 whose leading/trailing is unsharpened by an LPF9. The pulse train 13 is compared with the threshold voltage 15 by the comparator 10 and becomes a pulse train 14 and democulated by the LPF2. Since each pulse wifth of the pulse train 14 is controlled by the threshold voltage 15, even when the width and height of the output pulse of the monostable multivibrator 1 are changed, the amplitude of the demodulated output 5 is constant. Thus, the demodulation amplitude level is made constant without requiring high stability for the monostable multivibrator.

Filed: 1979-11-13
Abstract: PURPOSE:To reduce ghosts by simple circuit constitution with only one delay line. CONSTITUTION:Input video signal (a-2) has rise part V1 and ghost S1. Said signal is differentiated 15 to obtain differential values alpha1 and beta1. This differential output (b-2) obtains output (c-2) delayed by time nT by the 1st delay tapped delay line A. On the other hand, a vertical synchronizing signal is separated from the above- mentioned video input signal to generate a mask pulse, by which a peak detection pulse for detecting differential output alpha2 of the vertical synchronizing signal is generated to turn on switches 1b-nb. Consequently, differential value beta2 of the ghost delayed is stored from delay line A in memory C at the prescribed position. Then, the corresponding output of the 2nd tapped delay line E is multiplied by the output of memory C. The above-mentioned multiplication output is a video signal delayed time mT behind the original signal and from the input signal, the above- mentioned multiplication output by subtracter 17 to obtain output (g-2) having the ghost subtracted.

Abstract: PROBLEM TO BE SOLVED: To further increase the energy density of an electrical double layer capacitor.
