Title: Inverter apparatus
Inventor: NAGAI KAZUNOBU
IPC: H02P6/08
Filed: 1994-05-25
Abstract: PURPOSE:To prevent the generation of a current, which becomes the brake torque for a motor, by selecting switching elements, which perform on/off control on the basis of the on/off modes of pulse-width modulation signal among the switching elements on the positive side and the negative side, on the basis of the result of the judgment of a positive/negative judging means. CONSTITUTION:The position information of a rotor of a motor 15 is obtained with a position detecting means 17. The commutation timing is determined on the basis of the position information. A conduction signal is obtained with a microcomputer 41 corresponding to the timing. Switching elements 7-12 are driven by a driving means 42 on the basis of the conduction signal and the pulse-width modulating signal obtained with a pulse-width modulating circuit 23. The driving means 42 performs the on/off control of the transistors 7, 9 and 11 on the positive side in the on/off mode of the pulse-width modulating signal when the induced voltages of windings 15u, 15v and 15w in the non-conducting period are positive. When the induced voltage are negative, on/off of the transistors 8, 10 and 13 on the negative side is controlled. Therefore, the efficiency of the motor 15 can be improved.

Title: Automatic sampling device for liquid sample
Inventor: TAKI MASAHIRO
IPC: G01N35/00
Filed: 1990-04-26
Abstract: PURPOSE:To improve operability by selecting a figure inputting means and a moving instructing means with regard to a needle movement. CONSTITUTION:The selection of the moving conditions, such as file number of the information on the needle movement, the number of sample containers, the amt. of suction by a needle, the waiting time for analysis, etc., is started by a setting key 12 of a key operating section 5 and is executed by numeric keys 7 and a setting key 9. The selection is ended by operating an end key 13. An arithmetic processing section 20 calls the execution command for prescribed operation procedures out of a sequence table 22 when a sampling operation execution key 14 is operated. This section simultaneously calls out the moving conditions assigned by a pointer 23a in a transfer condition table 23 one after another, combines the commands and the transfer conditions, converts the combinations to command signals and sends the command signals to the control section 25. The sampling operation is thus executed via a needle moving mechanism 26. The sampling operation is assigned by keys 7, 9 when the information on the needle movement is set in the table 24. The operation is set by a key 11 for setting the information on the movement if this operation is not set. The operability is thus improved.

Inventor: OKABE TOSHIYUKI
IPC: H01L23/50
Filed: 1995-05-10
Abstract: PURPOSE: To provide a heat radiation part member wherein the exfoliation from a semiconductor chip or from sealing resin is hard to be generated by the temperature change due to the heat generated when the semiconductor chip is operated and by the temperature change just after resin molding. CONSTITUTION: A heat sink 14 is so sealed that the surface 20 opposite to the surface on which a semiconductor chip 12 is mounted is exposed from sealing material 26. The heat sink 14 consists of a plurality of constituent bodies, and exposed from the sealing material 26. The coefficient of thermal expansion of the constituent bodies in the central part B where the semiconductor chip 12 is mounted is more approximate to that of the semiconductor chip 12 than that of the constituent bodies of the peripheral part C. Thereby, the difference of expansion-contraction amount between the semiconductor chip 12 and the heat sink 14 which is generated by temperature change is reduced, and exfoliation and crack become hard to be developed between the semiconductor chip and the heat sink.

Filed: 1988-05-09
Abstract: PURPOSE:To increase durability by eliminating mechanical friction, by supporting a movable stage by a guide means in a suspended state and moving the same in X- and Y-directions. CONSTITUTION:A guide means 4 is constituted of a relay stage 20 and eight linear spring members 21.

Since the members 21 are mounted so as to form a pair through the relay stage 20, the total moving quantity of the movable stage 3 is 2delta and a change in a vertical direction is negated by the uniform distortion of the members 21 and the movable stage 3 can be moved in all directions within a horizontal plane without changing the height thereof.

Abstract: PROBLEM TO BE SOLVED: To nondestructively measure the propagation velocity of ultrasonic waves propagated through the surface layer of an object (particularly, a power cable) with higher accuracy. SOLUTION: The value of an expression L/(t<2> -T<2> )<1/2> (T and t and L are respectively found by vertical and obliaue methods) is used as the propagation velocity of ultrasonic waves in the surface layer A1 of an object to be inspected.

In the oblique method, the ultrasonic waves are transmitted obliquely inward from a transmitting means 3 on the surface of the surface and reflected waves from the interface between the layers A1 and A2 are received by means of a receiving means 4 positioned on the surface of the layer A1 by a distance L from the transmitting position, and then, the time (t) spent until the reflected waves are received after the waves W are transmitted is measured.
