摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric type pressure-sensitive sensor that can detect the contact between the pressure-sensitive sensor and an object even when the object comes into contact with the pressure-sensitive sensor at an extremely low speed, and a contact detecting device using the pressure-sensitive sensor. SOLUTION: The pressure-sensitive sensor 1 has a non-linear deflection member 3 exhibiting a non-linear displacement for a load, and a piezoelectric sensor 4 deformed by displacement of the non-linear deflection member 3. When a press load to the pressure-sensitive sensor 1 by an object exceeds a predetermined value, the non-linear deflection member 3 is sharply deformed and thus the piezoelectric sensor 4 is sharply deformed. Therefore, an output signal enough to detect the contact of the object with the pressure-sensitive sensor 1 can be achieved from the piezoelectric sensor 4, and the contact of the object can be detected by using this signal irrespective of the contact speed.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a friction force is generated between a coaxial and flexible piezoelectric material and a block type conductor and thereby the piezoelectric material tube cannot be moved at the time of moving the piezoelectric material tube and moreover a large force is required even when such piezoelectric material tube can be moved. SOLUTION: A conductive material block 6 provided with a piezoelectric material tube path 61 is divided. Friction force between one divided conductive material block and a piezoelectric material tube 3 is reduced by dividing the conductive material block 6 into a plurality of blocks. The piezoelectric material tube 3 can be moved with smaller force using a pulley 7 allocated at the folding- back area of the piezoelectric material tube 3. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To solve the problem that a coaxially flexible piezoelectric member cannot be wholly polarized in the case that defects are contained in the coaxially flexible piezoelectric member. SOLUTION: In this polarizing device, a piezoelectric member tube 3 is arranged in a path of a block-shaped conductor 6, high voltage is applied to the conductor 6 and a core electrode 1 of the tube 3, and a heater 7 is arranged which heats the conductor 6 and applies heat to the tube 3 arranged in the path of the conductor 6. Since the temperature of the tube 3 can be controlled by the above constitution, the coaxially flexible piezoelectric member 2 can be polarized at a necessary temperature. Furthermore, polarization is enabled except the coaxially flexible piezoelectric member 2 in parts containing defects, and it can be detected before an external electrode 4 is formed that defects exist in the tube 3 of a defined length.

摘要： PROBLEM TO BE SOLVED: To solve the problems that a concrete and reliable constitution for connecting a resistance for disconnection detection to a piezoelectric sensor is not expressed clearly on a conventional piezoelectric sensor, and that insertion is difficult when inserting the piezoelectric sensor into an inner hole provided in a rubber member because a printed circuit board becomes larger than the outer diameter of the piezoelectric sensor even if the printed circuit board is used when fixing the resistance. SOLUTION: A resistor 5 having the size smaller than the outer diameter of the piezoelectric sensor is connected between a core electrode 1 and an outside electrode 3, to thereby enable the outer diameter of a terminal part to be the same as or smaller than the outer diameter of the piezoelectric sensor, and hereby the piezoelectric sensor can be easily inserted and fixed in the inner hole of the mounting rubber member. Besides, a constitution wherein the long axis direction of the resistor 5 is squared with the coaxial direction of the core electrode 1, and one lead wire 6a of the resister is connected to the core electrode 1, and the other lead wire 6b is folded back and connected to the outside electrode 3, namely, the concrete and reliable constitution for connecting the resistance for disconnection detection to the piezoelectric sensor is provided.

摘要： PROBLEM TO BE SOLVED: To simplify assemblage, to reduce cost, to prevent itchy feeling even if a material adheres to a human skin at a work shop, and to improve work environment by installing an insulating plate to cover a heater, providing an insulating plate between a calcium silicium silicate board and a metal cover, and providing insulating spacers around the calcium silicate board. SOLUTION: An insulating plate 23 to cover a heater 2 is installed on the upper surface of a calcium silicate board 3, and a metal cover 4 is provided to hold the board 3 on the lower surface of the board 3. In this case, because the board 3 easily absorb moisture and has such a feature that its insulation is degraded in a high-humidity conduction, an insulating plate 24 is interposed so as to secure the insulation between the board d3 and the metal cove 4. A mica material is used for the insulating plates 23, 24. spacers 1 are arrayed around the board 3 between the metal cover 4 and the board in order to secure the insulation around the board 3, so that the insulation is secured and at the same time, the board 3 is held by them. Thereby, building-block type automation becomes possible.

摘要： PROBLEM TO BE SOLVED: To prevent an insulated substrate from degradation of its insulation caused by moisture absorption without using a glass fiber heat insulating material to improve the insulated heat insulating performance of a heating element in the heating element of a high-frequency heating device with electric heater. SOLUTION: The heating element of a high-frequency heating device with electric heater is constituted by forming a heater 2 on an insulated substrate 3, covering above of it by an insulating material, and involving a metallic cover 4 which stores and retains the insulated substrate 3 and the insulating material 1. Since the insulated substrate 3 has a calcium silicate material as its main component, by applying water repellant inorganic and organic materials to its surface, it is possible to ensure the insulating performance of the heater 2 even at a high temperature or high humidity. A heat insulator is not of such glass fiber type as a conventional one uses, therefore, a worker does not feel itchy even if it adheres to his skin at the time of working, thereby facilitating assembly work.
