Title: Frequency mixer
Inventor: TORITSUKA HIDEKI
IPC: H03D7/14
Filed: 1990-02-27
Abstract: PURPOSE:To obtain an excellent frequency mixer by connecting a transmission line whose wavelength is >=lambdag/2 being half the wavelength of a 1st RF signal between two drains so as to allow two high frequency signals subject to frequency mixing not to give any effect on the other signal source with each other. CONSTITUTION:A 1st RF signal F1 fed in common to gates 11G, 12G of FETs 11, 12 is outputted to drains 11D, 12D of the FETs 11, 12 in phase and a signal resulting from the output of the drain terminal 11D which is given to the other drain 12D via transmission lines 71, 72 and a capacitor 8 and a signal resulting from the output of the drain terminal 12D which is given to the other drain 11D via the transmission lines 71, 72 or the like are in phase. Moreover, the lines 71, 72 connected to the capacitor 8 when viewing from the terminals 11D, 12D of the FETs 11, 12 have a common reactance connected to them. Since the common reactance is selected to a desired value by selecting the length of the lines 71, 72 to be an optional length of lambdag/2 or longer, the FETs 11, 12 act like a frequency mixer efficiently with respect to the signal F1.

IPC: H04N1/40
Filed: 1982-03-25
Abstract: PURPOSE:To perform both gamma compensation and temperature compensation through simple circuit constitution, by detecting an ambient temperature and reading an ROM table wherein the compensation relation between the ambient temperature and conducting pulses is set on the basis of the detected temperature. CONSTITUTION:The output of a temperature detector 11 is inputted to the ROM table 13 through an AID converter 12. The ROM table 13 outputs a difference in the number of pulses between the ambient temperature level and reference temperature to an arithmetic circuit as an address signal. The arithmetic circuit 15 calculates a difference between the number of conducting pulses necessary to obtain print density of some gradation level at the reference temperature outputted from an ROM table 14 and the number of pulses outputted from the ROM table 14 and outputs it to a comparator 16. The comparator 16 compares the output of the arithmetic circuit 15 with the output of a counter 18 to sends an output to a gate circuit 19 when the both coincide with each other. On the basis of the output of the gate circuit 19, halftone recording to heat-sensitive paper is carried out.

Title: Adaptive voicing end detecting method
Inventor: NISHI HIROYUKI
IPC: G10L25/21
Filed: 1988-02-29
Abstract: PURPOSE:To detect the end of the voicing of a voicing person speedily with high reliability by providing a speech section length measuring means which measures the length of the voice of a user and varying the detection time of the voicing end according to the length of a speech section right before no voice is detected. CONSTITUTION:Knowledge regarding human habit is utilized to control the voicing end detection time adaptively by discriminating no voice in thinking time and no voice after the end of voicing. (1) The possibility that a long pause is generated after long voice like 'Well,...' is large. (2) The possibility that voicing is not finished after a voice with a large power value like '..., but' is large. (3) When the mean length of the pause observed after the start of the voicing is long, the length of the maximum pause time tends to be long and (4) when the frequency of a pause observed after the start of the voicing is large, the length of the longest pause time tends to be long. Therefore, when the mean length of a pause is long after emphasized sound after a long vowel, the generation end detection time needs to be set longer in case of the high generation frequency of a pause.
