Title: Manufacture of piezoelectric resonance element
Inventor: FUJINAKA YUJI
IPC: H03H3/04
Filed: 1994-06-30
Abstract: PURPOSE:To obtain the piezoelectric resonance element which varies a little in resonance frequency and resonance impedance owing to a thermal shock by heating piezoelectric ceramic up to specific temperature after baking, and then annealing it at a necessary temperature drop speed. CONSTITUTION:A piezoelectric composition is used and the piezoelectric ceramic is baked and heated up to higher Curie temperature and lower than grain growth start temperature. Then the temperature area including the Curie temperature is annealed at the drop speed of -50 deg.C/Hr--10 deg.C/Hr. Then a polarization electrode 2 is formed. This method relaxes thermodynamic unstableness generated in the crystal phase of the piezoelectric ceramic and the internal strain is also reduced. Even when a thermal shock is applied to the piezoelectric ceramic after polarization, variation in piezoelectric characteristics are suppressed small and the piezoelectric element which varies a little in resonance frequency and resonance impedance owing to the thermal shock is obtained.

Abstract: PURPOSE:To easily execute the adjustment of hardness of rice by providing a heater, a control means for controlling the heating quantity of the heater, a vapor adjusting means for adjusting the vapor discharging quantity of the inside of a container by setting at the time of rice cooking, and a pressure sensor for detecting pressure in the container at the time of a rice cooking state and sending a signal to the control means. CONSTITUTION:When for instance, 'rather hard' is selected among 'standard', 'rather hard' and 'rather soft' by an operating part 4 it is necessary that the moisture quantity in a container 5 is decreased from an initial state. A vapor discharging port 6 is enlarged by the action of a vapor adjusting means 7 so that moisture in the container 5 is discharged gradually to the outside. When the vapor discharging port 6 is enlarged, pressure in the container 5 is reduced, therefore, pressure in the container 5 is always detected by a pressure sensor 3, and a signal is sent to a control means 2. The control means 2 controls the heating quantity of a heater 1 in order to allow the pressure in the container 5 to be raised, so that prescribed pressure is obtained. By a series of operations thereof, rice of 'rather hard' can be cooked.

Title: Method and device for measuring vaporing water of timber decompressing dryer
Inventor: ASHIDA SUNAO
IPC: G01N25/56
Filed: 1980-10-24
Abstract: PURPOSE:To measure the amount of vaporing water of timber to be dried accurately by collecting in a metering container a condensated obtained by condensing vapor generated by decompressing and heating a pressure container containing timber to be dried, and by counting a frequency of discharge by discharging the condensate each time its amount reaches a prescribed value. CONSTITUTION:Undried timber 1 is mounted on a moving car truck 2 and installed in a pressure container 3, and a vacuum pump 5 is operated to perform decompression to a certain degree of vacuum; and a high-frequency oscillator 9 is put  in operation to start the high-frequency dielectric heating of the timber 1. Consequently, moisture moves from the internal layer part to the external layer part of  the timber 1 to vapor from the surface. The vapor is condensed by a condenser 4  into a condensate, which is collected in a metering container 6. As the condensate  reaches the level of an upper-limit water level detector 22, an automatic valve 13 is  closed and automatic valves 19 and 20 are opened to discharge the condensate into  the air. After the discharging, a lower-limit water level detector 23 operates to close  the automatic valves 19 and 20 and also to open the automatic valve 13, so that the condensate from the timber flows into the metering container 6 again. The frequency of discharge is counted to read the residual quantity of water by a water level gauge 21, thus measuring the residual quantity of water.

Title: Sub-chamber gas valve drive unit for gas engine
Inventor: KONDO MASANORI
IPC: F02B43/04
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To make the lift quantity of a sub-chamber gas valve smaller than that of an intake valve by offsetting the fulcrum center of a sub-chamber gas valve rocker arm rockable on the push rod side of an intake valve rocker arm to the sub-chamber gas valve side from the fulcrum center of a rocker shaft for supporting the intake valve rocker arm. SOLUTION: An intake valve rocker arm 2 supported by a rocker shaft 3 in a fulcrum center A swells the support part of a sub-chamber gas valve rocker arm 4 to approach (offset) a fulcrum center B to a sub-chamber gas valve 6 side from the fulcrum center A by a distance C (offset), and engages the tip of the sub-chamber gas valve rocker arm 4 with a sub-chamber gas valve 6. Accordingly, since the rocker ratio of the sub-chamber gas valve rocker arm 4 is smaller than that of the intake valve rocker arm 2, the lift quantity of the sub-chamber gas valve 6 is minimized. Consequently, the rocker ratio of the sub-chamber gas valve rocker arm 4 is properly selected, whereby the lift quantity of the sub-chamber gas valve 6 can be released from the limitation of the lift quantity in intake valve to minimize the capacity of the sub-chamber.

Title: Confidential communication system for facsimile
Inventor: AKIMA KOICHIRO
IPC: H04N1/44
Filed: 1987-06-18
Abstract: PURPOSE:To simplify confidential transmission operation by providing a nonconfidential data blank with an original read by the facsimile of a transmitting side and providing a control means which prints only nonconfidential data among received data on a recording paper and outputs it with the facsimile of a receiving side. CONSTITUTION:The facsimile of the transmitting side reads the data of the nonconfidential data blank 3 simultaneously with a confidential mark 2 and transmits them to the facsimile of the receiving side. The control means of the facsimile of the receiving side prints only the nonconfidential data among the received data received with a confidential code and outputs it. An addressee recognizes that a confidential communication comes to oneself by seeing the nonconfidential data copied on the recording paper and takes out the confidential data from the facsimile of the receiving side. Thus when a original 1 which informs the confidential communication as a graphic shows to the receiving side is sent, at the same time, the message informing that a confidential original is sent to the addressee is sent to the receiving side. As the result, the confidential communication operation of the facsimile can be simplified because it is sufficient that a transmitter requires only facsimile transmission operation.
