Title: Intermodulation preventing method for cordless telephone set provided with plural slave sets
Inventor: OKITA HIDETO
IPC: H04B1/04
Filed: 1991-07-23
Abstract: PURPOSE:To prevent intermodulation caused in RF transistor(TR) amplifiers at a final stage of a transmitter whose number is equal to slave sets built in a master set with a simple condition setting by selecting a TR with an excellent input output characteristic so as to form the TR amplifier. CONSTITUTION:A current of a collector side energized by a power supply voltage Vcc is set to be a peak of a flowing current at which intermodulation is minimized and a signal from an input terminal flowing to a bypass is suppressed by an inductor L2. Moreover, a base potential is kept constant by a constant voltage element D2 and the TR amplifier is in operation as the class A amplifier and in order to prevent the occurrence of intermodulation due to a very small current flowing to a constant voltage element Dr, a connecting point between the inductor L2 and the constant voltage element Dr connects to ground via a capacitor C4. Since a bias voltage is kept constant and a current feedback is applied, the collector current is not almost fluctuated even against each fluctuation as a current amplification factor of a TR Q, a power supply voltage, a temperature versus base error voltage to make the TR amplifier stable.

CONSTITUTION:A cylinder 10 is extended with the pneumatic cylinder 10 supplied with working air in a state that the movable shoes 16 and 16 of a transfer support device for a heavy article are attached. This thereby allows each movable frame 6 to be lowered, and also allows the movable shoes 16 and 16 to be lowered. And when the movable shoes 16 and 16 hit against an installation surface A, each end section at the pneumatic cylinder side of a right and a left arm 5 and 5 is pushed up by the pneumatic cylinder 10 by means of each reaction from the installation surface A side, so that each one of both of the right and left arms 5 is rotated around each shaft 4 to the direction that the movable shoes 16 and 16 are pushed down. By this constitution, the movable shoes 16 and 16 are pressed down onto the installation surface A, so that the heavy article can thereby be transferred while being lifted up.

Title: Angular modulation wave demodulator
Inventor: ARATA HIROO
IPC: H03D3/00
Filed: 1991-06-28
Abstract: PURPOSE:To prevent production of impulse noise by detecting a condition of production of the impulse noise in a demodulation output signal of a frequency modulation FM wave or a phase modulation PM wave from a high frequency signal before demodulation. CONSTITUTION:A discrimination circuit 3 discriminates it that an angular modulation high frequency signal of a reception input from a terminal 1 is not in the state of producing an impulse noise based on a threshold level when a complex circular integration value from a complex circulation integration circuit 2 is 0. When it is not 0, the discrimination circuit discriminates it that an input signal is in the state of producing an impulse noise based on the threshold level, generates a gate signal corresponding to the time width of the impulse noise to be generated as a discrimination output and it is inputted to a noise elimination circuit 4. The circuit 4 eliminates a part in the state of noise production and gives the result to an FM(PM) demodulation circuit 5, in which usual FM(PM) demodulation is implemented and a demodulation output signal is extracted from a terminal 6. Thus, no deterioration in picture quality due to production of a impulse noise due to a threshold level is caused even at reduction in the C/N of the reception input.

Abstract: PURPOSE:To measure moisture at a high accuracy, by measuring the temperature of a hot air to be fed to a drying chamber, the temperature of exhausted air and the temperature of outside air to determine the temperature of grains by calculating it from the results. CONSTITUTION:Grains are fed to an inflow section 3 and conveyed upward with a lift 23 at a lower discharge port 6 to be placed into a moisture conditioning tank 19. A hot air is admitted into a drying chamber 9 from a hot air feeding chamber 10 through a porous plate 12 and discharged through an exhaust air chamber 11 while the grains are flowing down thereinto 9 from the tank 19. When the grains are circulated to be dried in such a way, they are sampled just from the lift 23 and crushed to measure the moisture. The hot air temperature A, exhaust air temperature B and outside air temperature C are measured to calculate the grain temperature T=K1{K2.A+(1-K2) B}+(1-K1)C, wherein K1 and K2 represent constants. Thus, the grain temperature is calculated correctly thereby enabling the measurement of the moisture of the grain corresponding to the grain temperature.

Abstract: PROBLEM TO BE SOLVED: To manufacture a pavement flat plate of high quality at a low cost and in a short time by using a moisture-curing low viscosity adhesive and at the same time, injecting steam into a form where a kneaded bark is pressure- compressed. SOLUTION: Barks are ground and/or shredded and the size of these barks is adjusted in a sieving/sorting step and further, the barks are sufficiently mixed in a homogenizing/stirring step so that no qualitative variability occurs. In this case, an appropriate amount of wood chips is additionally mixed in order to enhance the binding strength and adjust the color tone and thereby upgrade the design characteristics. Further, a low viscosity adhesive is sprayed in a mist form to the barks with the help of a spray gun using compressed air, in such a process stage that the barks are moderately mixed in the homogenizing/stirring step. Finally, the material is transferred to a form molding step and saturated steam is injected into a mold where the material is properly compressed to harden the compressed material.
