Title: Dial type stop watch
Inventor: MORIYA TATSUO
IPC: G04C3/14
Filed: 1982-07-22
Abstract: PURPOSE:To allow users to recognize the display of the battery life more frequently by prolonging the time until the capacity of a battery runs out with a gradual decrease in the current consumption close to the complete expiration of the battery life. CONSTITUTION:In a 1/20sec drive controlling circuit 15, a step motor 17 is normally driven at 20Hz during the measurement except for the split display period until the battery comes close to the end of the life. With the battery very close to the end of the life thereof, the step motor is driven only for the period during which the measured time coincides with the indication position of a 1/ 20sec pointer when a signal is outputted to stop measurement or to direct the display of the times clocked part-way or the 1/20sec pointer indicates 0 position when a signal is outputted to direct the restarting of the time measurement or to release the display of the times clocked part-way. Thus, the current consumption can be reduced greatly very close to the end of the battery life more than before.

Title: Demodulator
Inventor: NAMIKI JIYUNJI
IPC: H04L27/22
Filed: 1982-07-22
Abstract: PURPOSE:To obtain a phase modulation signal demodulator which is screly affected by an input noise, by compensating in phase to the variance input carrier wave on a basis of the reversed series of time series obtained by sampling an input modulation signal, and obtaining a sampled value locked in phase. CONSTITUTION:The input modulation signal is inputted to a product detector 1, and a signal modulated to a low-frequency intermediate frequency by modulation data is outputted from the detector 1 to a sampling circuit 2. The circuit 2 samples the input signal and inputs N-number of sample values to a recording circuit 3 successively. The circuit 3 outputs sampled values in the order reverse to input, and they are inputted to a phase locked system 4, which follows up the carrier of the input signal, through a phase shifter 6 and a switch 5. When N-number of inputs are recorded in the circuit 3, the switch 5 changes the connection from the output of the circuit 2 to the output of the circuit 3 so as to lock the system 4 in phase with the reversed series of the output of the circuit 2. The shifter 6 subjects the output of the circuit 3 to the phase compensation based on the input signal carrier wave variance obtained from the system 4, and a reverse, time series of input signal sampled values of a carrier wave locked in phase is obtained from the output, and the phase modulation signal is demodulated.

Filed: 1981-08-17
Abstract: PURPOSE:To enable to prevent leakage of a microwave generated by vibration of a coil, by a method wherein a modulating coil is surrounded with conductive member which has an enough thickness to shut off the microwave and to enable a modulating high frequency to pass. CONSTITUTION:A conductor bar 2 pierces a cavity resonator 1 through holes 3 and 4, and is tightened to a resonator 1 by means of insulating bushes 5, 6 and nuts 7, 8 in a manner to maintain an insulation and a high-frequency current is supplied through feeding members 9 and 10. A copper film 12 with a thickness of about several mum is coated on an outer peripheral surface of a glass pipe 11 surrounding the conductor bar 2 with a gap between the gap and the glass fiber pipe. Thus, an electromagnetic field emanating from the conductor bar 2, can modulate a static magnetic field by the passage through the copper film 12. Besides, even if the conductor bar 2 vibrates violently thereupon, a microwave is shut off by the copper film 12, which does not vibrate, and does not reach surface of the conductor bar 2, and thereby the microwave is not modulated by the conductor bar 2.

IPC: A23L13/00
Filed: 1980-09-18
Abstract: PURPOSE: To prepare regenerated meat suitable as a raw material of various meat processing, and to obtain feed and fat as by-products, by grinding the meat attached to the bone in the presence of water, separating the product into liquid and solid, acidifying the liquid, and separating the coagulated meat.  
     CONSTITUTION: The meat attached to bones obtained by taking the meat of cattle, poultry, etc., is ground together with a proper amount of water. The meat is separated from the bone, and dispersed in water as colloid. The meat colloid is coagulated by adding about 10W15cc of an edible organic acid such as vinegar, acetic acid, etc. per 1kg of the meat used as the raw material. The coagulated meat is separated from the liquid by a solid-liquid separation means to obtain the objective regenerated meat. Since the regenerated meat is free of blood, it has no blood- originated defect in its taste, flavor and color, and can be used as a raw material of various processed meat products after neutralization with an alkali according to the use. The solid obtained by the fractionation of the ground product can be used as a feed or fertilizer after drying, and fat is collected by heating the liquid left after the fractionation of meat coagulate, and separating the coagulated proteins and hemoglobin from the liquid.
