IPC: H01L21/3205
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device suitable for an imaging device, such as a CCD and the like and a method of producing the same. SOLUTION: A semiconductor substrate 12 is etched on the rear surface opposite to the device forming surface, a through-hole 22 is formed opposite to a metal pad 20, a metal is deposited thereon by plating to form a bump 34. Since the bump 34 is formed on the rear surface of the substrate 12 and no obstacle is on the device forming surface, it is suitable for an imaging device. Instead of plating, a metal ball may be positioned and heat-treated on the through-hole 22, and the melt of the metal ball may be filled into the through- hole 22.

Title: Electric power steering device
Inventor: WAKAO HIROKAZU
IPC: H02K11/00
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To suppress an adverse effect caused by the abrasion of brushes by arranging the brushes face to face so that their sliding directions are made nearly horizontal, and arranging wiring holes above the brushes. SOLUTION: When a motor 50 and a controller 20 are stored in a common case 30, there is a possibility that the abrasion powder of brushes 58 generated in a motor chamber 39 infiltrates a controller chamber 38. The brushes 58 are arranged to be slid nearly in the horizontal direction, and wiring holes are arranged above the brushes 58. The abrasion powder of the brushes 58 is dropped and accumulated in an area below the brushes 58 in the motor chamber 39, thus the abrasion powder is prevented from infiltrating the controller chamber 38 through the wiring holes and causing the malfunction of the controller 20. When the pinching angle of wiring center lines is set to the range of 60-120 deg. and the height of the wiring holes against the brushes 58 is sufficiently secured, the abrasion powder is effectively suppressed from infiltrating the controller chamber 38 through the wiring holes.

Title: Wafer alignment fixing device
Inventor: ROBAATO II SUTEIAA JIYUNIA
IPC: H01L21/22
Filed: 1990-12-05
Abstract: PURPOSE: To simplify the matching of a notch, provided at the periphery part of each wafer in the wafer cassette of a wafer with a notch by 'dropping' the wafer onto a roller, when it matches the roller. CONSTITUTION: When a notch 13 around a wafer 12 does not matched to a roller 25 to be matched, the wafer 12 is arranged, so that it projects into the plane of the wafer being supported in a cassette 11, thus causing itself to be lifted from a side wall 14 when contacting the roller 25. A number of wafers 12 will likely be lifted slightly in the cassette 11. After that, a wheel 33 is rotated, so that it rotates the roller 25. For example, when the matched roller 25 is rotated clockwise, each non-matched wafer 12 is rotated counterclockwise. Each rotation of the wafer 12 stops, when the notch 13 is matched to the roller 25. At that time, the wafer 12 drops onto the support surface of a wedge block 42, and the roller 25 is separated from the notch 13.

Patent JP-H04216591-A (JP)
Title: Driving method for plasma display panel
Inventor: AWAJI NORIYUKI
IPC: G09G3/296
Filed: 1990-12-18
Abstract: PURPOSE:To reduce power consumption by stepwise varying the anode side power supply potential to the driving potential which is higher than the electric discharge initiation potential and to the electric discharge holding potential which is lower than the electric discharge initiation potential for every line period. CONSTITUTION:The anode side power supply potential Vy is normally kept at the discharge holding potential and is changed to the driving potential in a prescribed duration for every line period. When the anode side power supply potential Vy is at the driving potential, electrical discharges occur at the intersections of selected electrodes A1 to An and K1 to Km. Once the discharges occur, these discharges continue even though the anode side power supply potential Vy is lowered to the electrical discharge holding potential because electric charges are accumulated in the discharging space. Thus, the discharging current is limited because the anode side power supply potential Vy moves from the driving potential to the lower potential i.e., the discharge holding potential after the start of electrical discharges and the transition of the electrical discharges to arc discharges is prevented without electric current limiting resistors.
