Abstract: PURPOSE:To analyze the position and form of a probe where contact failure is apt to occur by attaching codes having X, Y co-ordinates, a probe form, a probe diameter and the like to individual probes which come into contact with designated positions on an IC mounting board. CONSTITUTION:In an inspecting device for an IC mounting board 1, X, Y co- ordinates are specified both on one solder side and the other part surface. Every pin comes into contact with a designated position on a board 1 to be sequentially attached with codes 2, and the codes 2 respectively show X, Y co-ordinates, a probe form, a probe diameter, and the distinction between the part surface and the solder side for individual probes. In the case of first starting a test to check the contact status of a pin, when an error does not occur, an analog test and a digital test are made as it is. On the other hand, when error display is made, immediately the position of the pin and the form of the pin are known without detaching the board 1 from the inspecting device 1.

Title: Ac type pdp driving method
Inventor: UKAI TAKEYOSHI
IPC: G09G3/293
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous lighting in the fighting keeping period and to realize a high quality display without flickering by making the pulse width of a fixed number of pieces of voltage pulses applied in the starting stage of the lighting keeping period shorter than those of another voltage pulses. SOLUTION: In a sustaining period TS, an address electrode A is biased to positive polarity potential for preventing a useless discharge, and initially a positive polarity sustaining pulse Ps1 is applied to all sustaining electrodes X. Succeedingly, the sustaining pulse Ps1 is applied successively to the sustaining electrode Y and the sustaining electrode X. Thereafter, the sustaining pulse Ps is applied alternately to the sustaining electrodes Y and X. In such a case, the pulse widths (w) of the first to third sustaining pulses Ps1 applied in the starting stage of the sustaining period TS are shorter than the pulse widths (w) of fourth sustaining pulses Ps and after that. Thus, a surface discharge hardly occurs in a non-lighting cell.

Abstract: PROBLEM TO BE SOLVED: To simplify a circuit for the detection of the rotor position of a brushless motor, reduce the number of components, detect the position of the rotor accurately and switch an armature winding to which a current is applied properly to improve the efficiency. SOLUTION: The armature winding voltages R, S and T of the respective phases of a brushless motor 4 are divided into predetermined voltages R1, S1 and T1 by a 1st voltage dividing circuit 10a. On the other hand, the one armature winding voltage R is divided into a predetermined voltage R2 by a 2nd voltage dividing circuit 10b, and the maximum value of the divided voltage R2 is detected by a maximum value detecting circuit 10c and is used as a reference voltage (k).

The control circuit 11 drives an inverter circuit 3 in a predetermined manner and controls the revolution of the brushless motor 4 in a predetermined manner. On the other hand, the respective cross points of induced voltages which are included in the divided winding voltages R1, S1 and T1 and the reference voltage (k) are obtained in accordance with the signals (a), (b) and (c) of the comparison results. Further, a time corresponding to 30 degrees is calculated in accordance with the time differences between the cross points obtained last time and the cross points obtained this time, and the armature winding of the brushless motor 4 to which a current is applied is switched when the calculated time passes after the cross point obtained this time.

Title: Shot peening method and treated article
Inventor: ROKUTANDA HITOSHI
IPC: B24C1/10
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To perform the peening of a treated product with high surface hardness by projecting the shot material with the prescribed grain size, the prescribed hardness and approximately spherical in shape and having the prescribed specific gravity. SOLUTION: Peening of the first stage is performed at the projection speed of approximately 75m/sec by the centrifugal projection system using approximately spherical shot material of 800-2000HV in hardness to a metallic work to be treated, and peening of the second stage is performed using the shot material having similar hardness. Because the specific gravity of the shot material is 11-20, high collision energy can be obtained though the speed in peening is low, and because the grain size is as small as 30-200 micron, the maximum residual compressive stress is effectively generated on the outermost surface.

Title: Color filter
Inventor: WATANABE KANE
IPC: G02B5/20
Filed: 1988-11-01
Abstract: PURPOSE:To shorten the process and to improve productivity by providing a transparent resin layer on which conductive fillers whose average gain size is <=0.4mum are dispersed, on the surface of a color filter layer. CONSTITUTION:On the surface of a color filter layer, a transparent resin layer on which conductive fillers whose average grain size is <=0.4mum are dispersed is provided with film thickness of at least >=1mum. That is, such a transparent resin is allowed to combine both a smoothing action of the surface of the color filter and an action as a transparent electrode. Accordingly, by setting the film thickness of the transparent resin layer to >=1mum, a step different of the surface of the color filter is relaxes, and the surface can be smoothened. Also, by setting the grain size of the conductive fillers dispersed on the transparent resin layer to wavelength of a visible light or below, no transparency of the transparent resin layer concerned is deteriorated. In such a way, the process is shortened and the productivity can be improved.

IPC: H05K3/34
Filed: 1988-11-02
Abstract: PURPOSE:To prevent corrosion of a terminal pin, solder and the like by specifying the length of the tip part of a terminal pin which is inserted into the through hole part of a printed wiring board with respect to the length of the through hole. CONSTITUTION:A length A of the tip part of a terminal pin 4 which is inserted into a through hole 3 of a printed wiring board 1 is made to be 0.93XB<=A<=1.2XB with respect to a length B of a through hole. Namely, when the length of the tip part of the terminal pin 4 is less than 93% with respect to the length of the through hole 3, solder cannot rise up to the upper surface of the through hole 3. When 120% is exceeded, bending of the terminal pin and leaking from the sealed part occur when the terminal pin 4 is inserted into the board 1 and a semiconductor is sealed. In this method, the solder rises up to the upper surface of the through hole in a soldering step for fixing the terminal pin, corrosion of the terminal pin, the solder and the like due to remaining foreign materials such as solder flux in the through hole part can be prevented.
