Title: Piezoelectric element
Inventor: ADACHI HIDEO
IPC: H01L41/09
Filed: 1987-03-10
Abstract: PURPOSE:To improve efficiency by forming boundary sections with groove- shaped notch sections in the thickness direction so that a piezoelectric element body is partitioned for each specific region. CONSTITUTION:A metal such as silver is applied onto the surface and rear of a ring-shaped piezoelectric body 20 manufactured by molding piezoelectric ceramics to a ring shape and cutting and polishing the piezoelectric ceramics in specified size through a means such as baking, and electrodes 21, 22 are shaped, thus constituting a piezoelectric element body. Partition boundary sections with groove-shaped notch sections 31-40 notched up to the depth of approximately half the thickness direction of a piezoelectric element body are formed to the surface of the piezoelectric element body so as to partition the surface of the element body for each specific region (eight regions of (a)-(d) and (e)-(h), holding a quarter lambda section M and a three quarter lambda section N). Accordingly, since the partition boundary sections with the groove-shaped notch sections 31-40 are shaped between the adjacent electrodes 21, 22, each polarization section 41-42 is easily brought to the state of saturated polarization accurately, thus inhibiting the generation of cracking due to polarization strain.

Title: Electrocorrosion resistant insulator
Inventor: ISHIHARA MASAMICHI
IPC: H01B17/02
Filed: 1990-03-05
Abstract: PURPOSE:To prevent any electrocorrosion generated in a pin fitting as well as any easy damage of an insulator caused by rust produced by the electrocorrosion by circumferentially disposing a buffer insulating material embedded in a cement in a part of a current flowing anode. CONSTITUTION:A side surface 11a of a current flowing anode 11 is covered with a buffer insulating material 12 made of silicone rubber. In the current flowing anode 11 embedded in a cement 9, a leak current is liable to flow in the vicinity of the surface of the cement 9 by the buffer insulating material 12 so that a portion of the current flowing anode 11 where electrocorrosion is generated can be limited to a small portion of the superficial layer of the cement 9. If rust is generated in the current flowing anode 11 by the electrocorrosion caused by damage or the like of the buffer insulating material 12, an inner pressure of the rust can be absorbed by an elastic force of the buffer insulating material 12, to this prevent any damage of a main insulator 1. Therefore, the electrocorrosion generated inside the current flowing anode can be restrained to the utmost, thereby preventing any fracture of the insulator.

Title: Catalytic combustion device
Inventor: IDA HARUO
IPC: F23K5/00
Filed: 1989-03-07
Abstract: PURPOSE:To eliminate the gas leakage from the title device by a method wherein the combustion amount of a catalytic combustion device is electrically controlled by an electromagnetic valve mechanism and a valve body is installed between a gas ejecting nozzle at the downstream side of a movable iron piece and the piece and also to carry out exact temp. control of the device by using an electromagnetic valve which can be driven by a battery. CONSTITUTION:Liquefied gas 2 in a fuel tank 1 is gasified when it passes through a resisting material 4 for air flow and when a power source switch 22 is ON, an exciting coil 10 is magnetized by an electric current from a battery 21 and attracts a movable iron piece 11 and a valve body 12 is opened. Thereby, the gas flows into the inside of a fuel supply passage 8 from an outlet 6 and is ejected from a nozzle 9. This ejected gas sucks air when it flows into a mixer 16 and the gas and air are mixed and supplied to a catalyst 17. Here, ignition is carried out and when the temp. of heated body 20 heated by the combustion heat of the catalyst 17 reaches a set temp., the contact point of a switch mechanism 19 is turned OFF and an electric current to the coil 10 is cut OFF and the piece 11 is pushed upwards by a spring 14 and the body 12 closes the nozzle 9. Then, when the temp. of a cylindrical body 18 is lower than the set temp., the contact point of the mechanism 19 is closed and the body 12 is opened and combustion is started again.

IPC: G01J5/02
Filed: 1985-03-19
Abstract: PURPOSE:To obtain a detecting element with higher sensitivity whose mechanical handling is easy by specifying the thickness of an element body made of a sinter above 125mum. CONSTITUTION:The exposed surface 2 of the element body 1 is irradiated with infrared rays (a) at a specific light chopping frequency, a pyroelectric current generated by the irradiation is received by a load with resistance 3, and a voltage developed across it is converted in terms of impedance by the source follower of an FET and compared with the power value of the incident power value to obtain their ratio, which is used to evaluate voltage sensitivity RV. Then, it is recognized that the voltage sensitivity RV tends to increase as the element body increases in thickness although the voltage sensitivity RV has variance depending upon the light chopping frequency. Further, it is confirmed that the voltage sensitivity RV becomes high where the thickness of the element body increases above 125mum, and the lower limit of the thickness of the element is limited to 125mum.

Filed: 1984-03-22
Abstract: PURPOSE:To obtain the optimum backward view in a running condition by automatically controlling the right-to-left inclination of a mirror of a rearview mirror device in response to the turning angle of a handle. CONSTITUTION:In response to the turning angle of a handle, resistance value of a variable resistor 11 of a handle turning angle detector increases and a comparator 31 transmits an operation signal for operating a relay 33 and a movable contact 33a of the relay 33 is connected to a normally open fixed contact. As the relay 33 is operated and a relay 34 becomes inoperative, a closed circuit composed of a d.c. supply E, contact 34b of the relay 34, movable contact 34a, motor 22, movable contact 33a of the relay 33, normally open fixed contact 33c and earth is completed, the moror 22 being forwardly driven. The rotation of the motor 22 causes a mirror to be inclined, and the resistance value of a variable resistor 23 increases. As the resistance value increases, the voltage value at the contact (a) increases, and the moror 22 is rotated, until the voltage value at the contact (a) becomes higher than that at the contact (c), so as to set the mirror to the optimum angle.
