IPC: H04N9/81
Filed: 1985-05-09
Abstract: PURPOSE:To remove a dislocation of a hue due to variance in a constant of a matrix circuit or a signal level difference by compressing three primary color signals respectively in a time base, dividing into two tracks to record, and recording the primary color signals as they are without converting to other signals. CONSTITUTION:1H memories 17-22 write and read input primary color signals R, G, B by a writing clock of a repetition frequency f1 and a frequency f2, respectively. The repetition frequencies f1, f2 select the primary color information per 1H so as to transmit within (2/3)H. Time base compression signals alternately read from the 1H memories are synthesized in time series in switch circuits 23-25 and three types of time base compression primary color signals are successively divided to two transmission passages by switch circuits 26, 27. Then, they are supplied to rotating heads 36, 37 through a synchronous pulse and discriminating signal adding circuits 28, 29, an emphasis circuits 30, 31, FM modulators 32, 33 and recording amplifiers 34, 35, to form two tracks at the same time on a magnetic tape individually.

IPC: H05H1/46
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To prevent a hunting state for rapid matching when reflected-wave power is produced. SOLUTION: According to this method for controlling magnetron output of a device supplying plasma load 18 with an output of a magnetron 17 that generates microwaves, a signal Ea corresponding to traveling-wave power and a signal Eb corresponding to reflected-wave power are detected or computed.

Title: Privacy telephone set
Inventor: TAMURA SHINICHI
IPC: H04K1/06
Filed: 1984-05-17
Abstract: PURPOSE:To obtain an excellent privacy call signal with simple constitution by multiplying an input signal with a window function, extracting the result, replacing plural parts at each signal, multiplying a widow function specified by the former window function with a signal formed through plural number of repetition of the replaced signal, and synthesizing the result sequentially and outputting the result. CONSTITUTION:An output result of a multiplier 5 is written in a ROM20. In case of N=32, M=32, R<=8 is attained through the extraction of a shift register 3. Then the data written in the ROM20 is read by an address of, e.g., n (7n). Thus, a signal equal to the replacment as k (23k) is read in the frequency region by the Fourier transformation from a RAM20. The point number is increased double by the frequency region and a data of the time region by an inverted FFT of spectrum data string where the odd number data is brought into logical ''0'' is equal to the x(m) with doubled period. Then data of 232 words from the RAM20 are transmitted to a buffer memory 21 so as to form data of 64 words where data of 32 words are repeated twice.

Abstract: PURPOSE: To eliminate the improper elongation of an annular fluorescent lamp at heating time and the improper molding thereof at molding time by heating to soften unmolded lamp bulb in a heating furnace and to take it out, and winding it from the lower end onto a molding drum to thereby form an annular shape while continuously heating the upper end of the bulb.  
     CONSTITUTION: Unmolded fluorescent lamp bulb 1 retained elevationally by a holder 3 is contained in longitudinally divided heating furnace while supplying nitrogen gas from an evacuating tube 2 to heating to soft it and to take it out of the furnace. Then, a burner 4 is approached to the bulb 1 by an air cylinder 6 to wind the lower end of the bulb 1 on a molding drum while continuously heating the upper end of the bulb 1 and the gripper of the holder 3. When the burner 4 is retarded by the air cylinder 6 to extinguish the flame, the bulb 1 is cooled to be solidified while being wound on the drum. Thus, it is not necessary to excessively heat the upper end of the bulb in the heating furnace so as to thereby eliminate the improper elongation of the lamp at heating time and the improper molding thereof at molding time.

Filed: 1982-06-10
Abstract: PURPOSE:To obtain a semiconductor device by suppressing sensitiveness of resist at the non-exposed recess part due to the light beam reflected from the exposed projected part in the photo etching process among the IC manufacturing processes. CONSTITUTION:A device is formed with silicon 11, resist 12, aluminum 13 and CVD SiO2 layer 14. First, exposure, development and etching of the structure part which causes reflection of light beam are carried out. For example, the aluminum is etched only for the area enclosed by the broken line in the figure. Next, exposure, development and etching of the desired final pattern are carried out. By such processing, the light beam is no longer reflected from the stepped inclined surface of projected area and sensitiveness of resist at the non-exposed recess part due to the light reflected from the exposed projected part can be suppressed. Accordingly, it is no longer necessary to design a thick center ridge line.
