Title: Temperature measuring method using thermocouple
Inventor: IWASHITA YOSHIHARU
IPC: G01K7/02
Filed: 1991-12-11
Abstract: PURPOSE:To make it possible to measure temperature accurately and safely by filling the space between a material to be measured and a thermocouple with low-melting-point metal, and reducing the contact thermal resistance of the thermocouple with the material to be measured. CONSTITUTION:A measuring hole 3 is formed in the surface of a material to be measured 2 made of a metal plate material such as a copper plate for continuous casting mold. A ring-shaped low-melting-point metal 13 having, e.g. a hole part, is filled at the bottom part of the measuring hole 3. A thermocouple 1 is inserted into the hole part. Metal powder 4 such as copper powder is filled, and the upper part is fixed with fixing agent such as instantaneous bonding agent. Thus, the backlash of the material to be measured 2 and the contact thermal resistance caused by physical factors such as vibration can be suppressed to the very low values, and the accurate temperature measurement can be performed. It is not necessary to bring the tip of the thermocouple into direct contact with the material to be measured, and the life of the thermocouple can be made long.

Title: Shock noise prevention circuit
Inventor: MATSUOKA HIROTO
IPC: H03F3/68
Filed: 1991-12-12
Abstract: PURPOSE:To reduce shock noise caused by a difference between the capacitance of two NF capacitors in a BTL system audio power amplifier. CONSTITUTION:The circuit is provided newly with a bootstrap limit circuit 12 and a changeover switch circuit 13. Just after the operation of a bias SW9, a potential across bootstrap capacitors C3, C4 is controlled by the bootstrap limit circuit 12 to set a 1st output 5 and a 2nd output 6 to a potential close to a midpoint potential. After the changeover, the switch circuit 13 is used to set the potential across bootstrap capacitors C3, C4 is set to the usual potential. Since the potential between the 1st output 5 and the 2nd output 6 before and after the start is small, even when the timing of the start of the 1st output 5 and the 2nd output 6 is deviated, the potential difference is small and generated shock noise is small.

Title: Position sensorless motor controller
Inventor: IIJIMA TOMOKUNI
IPC: H02P27/04
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To control a motor efficiently by generating a reference value of current variation based on a current or a current command value being fed through a stator winding thereby generating an estimation angle of a rotor accurately. SOLUTION: In a controller comprising a microcomputer 8 for controlling a brushless motor 5, a sensorless control section 30 starts a voltage pulse generating section 31 every set time and delivers a d-axis voltage pulse vd* and a q-axis voltage pulse vq* to the voltage command value generating section 13 in a current control section 10. A variation generating section 41 generates a d-axis voltage variation Δid and a q-axis voltage variation Δiq. In order to eliminate the effect of magnetic saturation due to increase of a current command value ia, a shift generating section 42 generates a shift eθ using a reference value of current variation generated based on the current command value ia. Subsequently, a lead generating section 43 generates a lead Δθ and delivers it to an estimation angle generating section 16 and also inputs it to a speed generating section 44 thus generating a speed value ω of the rotor 3.

Abstract: PROBLEM TO BE SOLVED: To prevent an injury or other accidents such that a rotating brush in a section port body contacts a finger, hand or other parts of a user by disconnecting a controlling and detecting means from each other when the suction port body is reversed. SOLUTION: A suction port body contains a detecting means 8 connectable to a long switching board 74 in a limit 71 as the controlling means, and the detecting means 8 comprises a movable part 82 and a connecting part 81, where the connecting part 81 is connected to the movable part 82 almost at the center in such a way that its connecting side, i.e., the long switching board 74 side, is slanted only in a direction opposite to the long switching board 74, and is connected to a weight 83 at the other side of the connecting side to the movable part 82. When the suction port body 1 is reversed, the long switching board 74 in the limit 71 as the controlling means is disconnected from the connecting part 81, because the connecting part 81 is slanted due to the unbalance by the weight 83 from the horizontal position.

Filed: 1992-12-09
Abstract: PURPOSE:To provide a pneumatic radial tire in which a responsiveness and a grip have been improved without lowering drainage during driving on a dry road and no distinction between right and left tires is required when the tire is assembled to a rim. CONSTITUTION:In a tread 12, plural continuous grooves 18 forming a half circular arc are formed in the tire circumferential direction, and their both end parts are connected to tread end parts 12B. The continuous grooves 18 are symmetrical shapes in the tire circumferential direction setting tire meridians 20 as axes of symmetry. The continuous grooves 18 are arranged continuously so that one continuous groove 18 has four intersections with other continuous grooves 18.
