Title: Semiconductor device
Inventor: NEZU TOSHITADA
IPC: H05K1/18
Filed: 1989-05-08
Abstract: PURPOSE:To prevent the short circuiting between adjacent connection terminals even in the case where a bump electrode is fused and yields up to the pressing force of a piston, by interposing stoppers as obstracles between the surface of a semiconductor integrated circuit and the surface of a wiring board. CONSTITUTION:Washers 18 are formed on a module 3 and the surface of a wiring board 2 corresponding with the module, and bump electrodes 13 are arranged so as to connect both of the washers 18. Protruding stoppers 20 are formed on parts of the wiring board 2 so as to keep away from the positions of the bump electrodes 13. As a result, when a semiconductor integrated circuit 3 is heated, and the bump electrode 13 is fused to yield to the pressure of a piston 14, the gap between the surface of the semiconductor integrated circuit 3 and the surface of the printed wiring board 2 is kept constant, ad solder material can be prevented from stretching toward the surface direction. Thereby the short circuiting between adjacent connection terminals caused by solder material can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of an error between the end face of a gear and a snap ring provided on the rotary shaft at a working stage by interposing an elastic member between the end face of the gear fixed to a rotary shaft relatively non-rotatably to the shaft and the snap ring provided on the shaft. SOLUTION: An annular groove 2b is punched to fit a belleville spring 9 to be a snap ring 8 and an elastic member adjacently to the end face of a gear 3 which is fixed to a rotary shaft 2 so that the gear 3 may be relative revolution impossible on the outer periphery of a rotary shat 2. The shaft line direction width and location of the annular groove 2b provided around the rotary shaft 2 are made the ones in which the belleville spring 9 is energized to the end face of the gear 3 by the snap ring 8 and is properly and elastically deformed. Thus, the gear 3 is prevented from moving in the shaft line direction to the rotary shaft 2 by constituting the belleville spring 9 supported by the snap ring 8 to energize the end face of the gear 3. An O-ring may be used as an elastic member in place of the belleville spring 9.

Title: Antidazzle reflection mirror
Inventor: SATOU MAKOTO
IPC: G02F1/139
Filed: 1984-06-04
Abstract: PURPOSE:To obtain a satisfactory antidazzle effect with a lower voltage by subjecting a liquid crystal to a twist orientation twisted continuously 90 deg. between upper and lower substrates. CONSTITUTION:DSM arises from the refractive index anisotropy in the liquid crystal by the circular columnar circulating flow generated in the direction perpendicular to the direction of the orientation treatment. Such circular columnar circulating flow is generated in the diameter of about the same diameter of a cell gap at about 8V. The flow is smaller in diameter, larger in number and is more strongly scattered as the voltage increases. Since the orientation treating directions of the upper substrate and the lower substrate intersect with each other, the orthogonal circular columnar circulating flow is generated. The vertical and horizontal fringes are microscopically observed in a mesh shape. The TN orientation is more random in the refractive anisotropy and is more strongly scattered.

Filed: 1988-05-11
Abstract: PURPOSE:To use the main body of a hand-free telephone set in common with a telephone set without a hand-free function by using one indicating means jointly for indicating two states. CONSTITUTION:When a speaker 4 is in a state capable of receiving a speech and a microphone 3 is in the state capable of sending the speech, a two-colored LED(light emitting diode) 6 is lighted in a green color. When the speaker 4 is in the state capable of receiving the speech and the microphone 3 is in the state inhibited to send the speech, the two-colored LED 6 is lighted in a red color. Besides, when the speaker 4 is in the state inhibited to receive the speech and the microphone 3 is in the state inhibited to send the speech, the two-colored LED 6 is turned off. Thus, since the operating states of the speaker 4 and the microphone 3 can be indicated by one two-colored LED 6, the main body can be used in common with the telephone set without the hand-free function.

Title: Signal processing for oxygen saturation measurement of vital tissue especially for human being
Inventor: PIITAA ROZAA
IPC: A61B5/145
Filed: 1989-05-09
Abstract: PURPOSE: To realize a high sensitivity measurement by passing a signal through a filter which exhibits blocking characteristics for the frequency range of spurious signal and exhibits transmission characteristics for the frequency range of information signal and processing the filter signal to block the spurious signal. CONSTITUTION: For example, a pickup 2 is provided with light emitting elements 3a-3c emitting a light beam 6 sequentially with wavelength λ1 -λ3 , respectively. A light beam 9 reflected on a hemoglobin 8 impinges on a light receiving element 4 together with a spurious signal caused by an ambient light 17. Outputs U1 -U3 from the element 4 are delivered through a high-pass filter 14 to an evaluation circuit 16. A function representative of deviation of the frequency response of a filter 14 from ideal transmission characteristics is determined in the frequency range of information signal. Subsequently, an inverted function thereof is determined and the output from filter 14 is weighted according to the inverted function. Since the output signal from filter 14 is subjected to inverted electrical processing, distortion due to the filter 14 is eliminated completely.
