Title: Piezoelectric pressure sensor
Inventor: KUSAKABE HIROKI
IPC: G01L9/08
Filed: 1989-12-14
Abstract: PURPOSE:To miniaturize an attaching screw part of a sensor for combustion pressure in a cylinder and the like by inserting a push rod into a tubular part from the tip of the attaching screw part to a diaphragm, and bonding the push rod to the diaphragm. CONSTITUTION:A sensing part 23 is brought into contact with and fixed to an attaching screw part 21 through a sealing member 28 only at a contact part 21a with a fixing screw 23a. A push rod 22 is bonded to a diaphragm 24 and can be moved in the axial direction in correspondence with applied pressure. In this constitution, pressure which is applied on the rod 22 because of the pressure fluctuation generated in a region to be measured is correctly transferred to the diaphragm 24 and further transferred to the inner surface part of a piezoelectric element 26 through a pressure transfer member 25. The outer surface part of the element 26 is fixed with a fixing screw 27. Therefore, shearing stress is generated at the inside of the element 26. Electric charge is generated at the inner and outer electrode parts of the element 26. In this way, gas resonance and deposition of deposit material do not occur, and the attaching screw part can be made compact.

Title: High-frequency heating rice cooker
Inventor: HATANO TAKESHI
IPC: A47J27/00
Filed: 1994-12-27
Abstract: PURPOSE: To prevent uneven heating with a simple structure by designing so that a projection which is provided at the under side of a lid and is projected to a pot receives microwave radiated from the opening of a wave guide. CONSTITUTION: When appropriate amounts of rice and water are put in a pot 3, the pot is set in a main body 1, and power is applied to turn the start switch on, a drive circuit 10 starts its operation. A heating coil 6 generates a high-frequency magnetic field to induction-heat a metallic pot 3, a pressure-rise transformer 11 supplies high voltage to a magnetron 4 to make an antenna 4a send a microwave. A part of microwave which is radiated from a wave guide 7 and goes straight is reflected at the surface of a projection 12 provided at a lid 2a and is scattered. This scattering eases the concentration of electric field by the microwave to prevent a local concentration of heating. Therefore, rice and water in the pot 3 are heated by the induction heating and the microwave, and delicious rice is cooked in a short time.

Title: Cross coil meter
Inventor: MIZUNO TORU
IPC: G01R5/16
Filed: 1987-12-23
Abstract: PURPOSE:To keep a meter indicating needle at the original position without changing the indicating position even in case a main electric power source circuit is interrupted for many hours by providing a sub-power source circuit to supply the power to a field coil intermittently in a constant cycle when the main power source is not in the operation. CONSTITUTION:When a main power switch 1 is interrupted, a switching circuit 3 is made to be OFF whereby the electric power supplying to a meter part 4 is interrupted. An output is generated from a timer IC21 with its timing-up and the switching circuit 3 is made to be ON operation through a diode 62. This ON operation is continued until an electric charging voltage of a capacitor 24 is elevated over a constant value thereby a 'L' level output is generated from a gate 22. The ON operation of the switching circuit 3 is repeated intermittently for one minute every sixty minutes by the sub-power source circuit 2 including the timer IC21, and a battery power is periodically supplied to the meter part 4. At the time of non-electric supply, even if the meter indicating needle 44 is slightly shifted from the original position by its own unbalance or an effect of terrestrial magnetism, the aforementioned indicating needle 44 is again returned to the original position by the continued electric supply for one more minute. Thus the position of the meter indicating needle is correctly kept even when the main power switch is interrupted.
