Patent JP-H01181233-A (JP)
Title: Transmitter
Inventor: NAKAMURA EIJI
IPC: H04B17/318
Filed: 1988-01-13
Abstract: PURPOSE:To attain simple component constitution and miniaturization mixing an output from a local oscillation means and a received radio wave, detecting a beat output produced by mixing, keeping the reception state when the output is detected, and shifting the output frequency of the local oscillation means to use the result as the transmission frequency when transmission operation is applied in a state where the output is not detected. CONSTITUTION:When a radio wave of the same frequency as the transmission frequency 123,000MHz of the transmitter of 12,303MHz is supplied to a mixer 10, the frequency is mixed with the frequency 123001MHz from an oscillation section 6 and a beat signal of 1kHz is outputted to a band pass filter 11. Since a detector 12 has an 'H' output in the absence of 1kHz input and has an 'L' output in the presence of 1kHz input, an 'L' output is fed to a NAND 13. Thus, even when a transmission switch 14 is operated, the NAND 13 is not always changed but keeps the 'H' output, then a relay 15 is not energized. When the transmission switch 14 is operated with the output of the detector 12 at 'H' state, the capacitance connected in parallel with a crystal oscillator 4 is increased by the capacitance of a capacitor 5, the center frequency output of the oscillation section 6 is shifted to 123000MHz toward lower direction.

Title: Foam molding
Inventor: KUDO YASUTAKE
IPC: B29L31/58
Filed: 1989-01-14
Abstract: PURPOSE:To mold an extremely excellent urethane foam having no flashes, no sink marks and no voids by using a mold provided with a urethane skeleton foam impregnated with a foam breaker at the end of a cavity and carrying out foam molding of urethane. CONSTITUTION:A Scott foam 7 impregnated with a foam breaker is used as a variable sealing section at the terminal of a cavity formed with a top force 1 and a bottom force 2 for sealing the terminal of the cavity. As the cavity terminal is sealed with air permeable Scott foam 7 impregnated with the foam breaker, gas in the cavity can be released out of the mold at the time of foam molding, and voids are not generated. The foams of urethane foam 5 reaching the cavity terminal is destroyed by the foam breaker applied to the Scott foam 7 to prevent said urethane foam from expanding. Thus, the urethane foam is prevented from flowing out of the cavity to eliminate the generation of flashes and sinking marks.

Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To directly produce the subject liquid crystal material without using a solvent and a base and dispensing with complicate post-treatment simply by deacetylating a specific compound having phenolic acetate groups with a specific carboxylic acid compound. SOLUTION: A planar condensed-ring compound containing >=6 phenolic acetate groups in one molecule and a >=6C carboxylic acid compound are subjected to deacetylation reaction. The deacetylation reaction is preferably carried out in a reactor provided with an acetic acid outlet port to distill out the by-produced acetic acid. The reaction is performed under reduced pressure or in an inert gas flow after the time when the amount of the distilled out acetic acid reaches 30-95wt.% of the theoretical amount. The planar condensed- ring compound is especially preferably 2,3,6,7,10,11-hexaacetoxytriphenylene. A discotic liquid crystal material having excellent thermal stability and high- temperature reliability and exhibiting particular optical characteristics can be produced by this process directly as a reaction product. The material is useful as a material for optical elements.

IPC: H03F3/16
Filed: 1982-01-19
Abstract: PURPOSE:To obtain a wide frequency band by using a sampled value circuit at the initial stage of an operational amplifier as a substitute for a differential amplifier. CONSTITUTION:P-Channel transistors (TR) Q1, Q2, Q5, and Q6 constitute a COMS output stage and N-channel TRs Q3, Q4, Q7, and Q8 constitute a bias circuit which supplies a proper bias voltage to the CMOS output amplification stage. Switches (SW) S2, S3, and S4 are turned in turn by out-of-phase clock signal phi1 and phi2 having a 50% duty cycle. An input signal is supplied to an inverted input terminal N1 and a voltage from a constant voltage power source is appled to an uninverted input terminal N2. A capacitor C1 is connected between the connection point N3 between the SWS1 and SWS2 and the connection point between the SWS3 and TRQ1, and a capacitor C2 is connected to the connection point between the SWS4 and TRQ4. Consequently, the input signal is sampled by the clock signals and the operational amplifier which has less power consumption and wide frequency band width is obtained.

Title: Constant-voltage power source unit
Inventor: YAMAZAKI TSUKASA
IPC: G05F1/56
Filed: 1985-01-17
Abstract: PURPOSE:To make a charge time constant small, to make a discharge time constant large, and to obtain a device whose output voltage variation is small even for an input voltage having a large ripple variation, by constituting a filter circuit of a diode and a capacitor. CONSTITUTION:A reference voltage is obtained by a resistance 83 and a Zener diode 84 from an output of a rectifying device 2. If there is a large ripple variation in an output of the rectifying device 2, its reference voltage is also varied, but by a diode 95, when a ripple variation increases, a capacitor 94 is charged immediately, and when it decreases, the discharge is obstructed, and a variation of the base potential of a control use transistor 12 is reduced. In this way, even for an input voltage having a large ripple variation, a variation of an output voltage can be decreased without increasing the capacity of the capacitor 94.
