Title: Control method for converter which obtains dc from multiphase ac
Inventor: CHIN GEIHO
IPC: H02M7/219
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To minimize the AC distortion factor, while securing the property following, and also, minimize the occurrence of ripples. SOLUTION: A DC controller 7 obtains an AC command value from the difference between a DC command value and the quantity of DC control, and gives the AC command value to an AC controller 4. The AC controller 4 sequentially selects two switching vectors in one control cycle. An optimum switching timing computation means 3 switches the vector from the first vector to the second vector with a specified timing. For the selection of the first vector, an optimum vector is selected so that the terminal error in one control cycle may be minimum. Moreover, for the selection of the second vector, supposing that the first vector is selected, the vector which can minimize the terminal error is selected, when switched to the second vector with the above switching timing.

Title: Die bonding method
Inventor: UNO TOSHIHIKO
IPC: H01L21/301
Filed: 1990-10-22
Abstract: PURPOSE:To improve efficiency of die bonding work by formimg a solder bump, in a desired shape with a desired thickness, on a heat sink by means of ineft gas ejected through a nozzle. CONSTITUTION:The surface of a heat sink 1 is heated and a solder 2 is fused thereon. Inert gas is then ejected through a nozzle 3 in order to spread the solder 2 on the surface of the heat sink 1. A semiconductor element 4 is mounted on thus spread solder 2 and then the semiconductor element 4 is pressed against the heat sink 1 thus bonding the semiconductor element 4 to the heat sink 1. When the flow rate of the inert gas is increased, the solder 2 can be spread over a wide area by the injecting pressure. On the contrary, when the flow rate of the inert gas is decreased, spreading of solder 2 is restricted. Consequently, the shape and the thickness of solder bump can be optimized for semiconductor elements 4 having different sizes by simply regulating the flow rate of the iner gas.

Title: Equipment and method of economizing memory for displaying raster test pattern
Inventor: ROBAATO JIERAADO BASUMAN
IPC: H04N17/00
Filed: 1989-11-02
Abstract: PURPOSE: To save a memory by using a comparator which can predict on which scanning line valid display information is present in a raster test pattern display device. CONSTITUTION: A Y register 14 holds the value of a scanning line including picture information, and an X register 12 holds the horizontal position of the picture information. Those X and Y values loaded to each register 12 and 14 of comparators 18 and 20 are compared with the outputs of a horizontal counter 4 and a vertical counter 6 which generate a raster timing by the comparators 18 and 20. When the value reaches a Y value being a correct scanning line, this device is turned into a waiting mode to a correct X position on the scanning line. Then, video data are loaded to a parallel input and serial output shift register 16. Thus, a device which displays a raster test pattern which includes nothing for a blank test pattern can be realized.

Title: Magnetic head
Inventor: MATSUURA SHINJI
IPC: G11B5/60
Filed: 1991-10-31
Abstract: PURPOSE:To decrease medium-sliding contact surfaces and to obtain the magnetic head having a good head touch by forming chamfered parts on the medium advance side of the medium-sliding contact surfaces. CONSTITUTION:The 1st medium-sliding contact surfaces A are decreased by the formation of the chamfered parts F when the medium D travels between two pieces of the magnetic heads and, therefore, the head touch of a magnetic gap 1 and the medium D is improved. Since the medium advancing port C narrows gradually from the part of the expanded flank E toward the sliding- contact surface A side, the air flowing to the periphery of the advancing port C flows smoothly between the magnetic heads and the large resistance is no longer applied to the medium D. Thus, the medium D travels at the small spacing quantity between the sliding contact surfaces A facing each other while maintaining the flat state. Consequently information is recorded and reproduced to and from the magnetic gap 1 with the good head touch.

Abstract: PROBLEM TO BE SOLVED: To correct convergence deviation by moving the display positions of 1st and 2nd adjustment patterns in a prescribed direction to minimize the difference of output signals provided, when these adjustment patterns are selectively alternately outputted. SOLUTION: For a 1st adjustment pattern P1 , its luminance level becomes a peak at a point (a), and its luminance lowers gradually from a point a1 to a point (b) and becomes a '0' level at the point (b). A 2nd adjustment pattern P2 has change characteristics in reverse to the 1st adjustment pattern P1 , its luminance level is gradually increased from the point (a) and its luminance reaches a peak at the point (b) and becomes a '0' level later. Then, the 1st and 2nd adjustment patterns P1 and P2 are alternately displayed, while being switched at prescribed timing, the luminance level between the points (a) and (b) is detected by a photodetection part. The respective adjustment patterns P1 and P2 are moved so that the luminance level difference between the respective adjustment patterns P1 and P2 can become a minimum value.  Namely, by changing the luminance level, the convergence deviation can be corrected.

Title: Ultrasonic apparatus for measuring abrasion of wheel
Inventor: ORIKI KENICHI
IPC: G01B17/00
Filed: 1989-11-02
Abstract: PURPOSE:To make it possible to measure the local abrasion of a wheel in the circumferential direction automatically under the wheel running state by transmitting an ultrasonic wave into a rail, receiving the reflected wave from the contact point between the rail and the wheel, and measuring the distance to the wheel contact point at each position. CONSTITUTION:The reciprocal propagating time T of an ultrasonic wave in a rail between a probe 1 and each of wheel contact points 2a - 2d becomes the relationship T = 2X/V (X is the distance between the probe 1 and each of the contact points 2a - 2d, and V is a sound speed). The distances to the contact points 2a - 2d can be measured based on the propagating time T. The sound part of the wheel 6 without local abrasion is in continuously contact with the rail 2, and the running distance of the wheel 6 and the positions of the contact points 2a - 2d agree. When the flat-shaped local abrasion as shown by the contact points 2b - 2d is present in the circumferential direction, the wheel 6 comes into contact with the rail 2 only intermittently. The change in distance of the contact part is very sudden in comparison with the sound part. Therefore, in a local-wheel-abrasion operating and outputting part 5, the distance change of the contact parts 2a - 2d due to the wheel running is compared with the sound part. The wheel running section which is different by the value exceeding a predetermined range or more is computed and outputted as the circumferential distance of the local abrasion.
