Patent JP-H06275604-A (JP)
Title: Semiconductor device
Inventor: KIKUCHI MASAHIRO
IPC: H01L21/31
Filed: 1993-03-19
Abstract: PURPOSE:To provide a highly reliable semiconductor device in which cracks appearing in a final passivation film are fundamentally prevented. CONSTITUTION:A semiconductor device is a device where an expression, A>=0.01(mum<-1>)X-BXC holds when the thickness of a final passivation film 3 is expressed as A, the sum of the thickness of the film of the electrode wiring 4 of, at least, one layer, is expressed as B, and the width of a line of the electrode wiring 4 is expressed as C in a semiconductor device. Thus, when the final film is thickened to maintain this relationship, the stress exerted on this film itself will be small, and the stress is dispersed to make the localized concentration small, thereby preventing the influence of the stress exerted from a mold material to the electrode wiring without any cracks caused in the final passivation film.

IPC: G06F3/043
Filed: 1978-05-23
Abstract: PURPOSE: To prevent the S/N lowering caused by the external noise in case the length of wiring is increased between the piezoelectric element and the voltage detector circuit by applying the current detection system for the voltage detector circuit of the position detecting pen, and thus to increase the S/N for the output signals.  
     CONSTITUTION: The vibrations of pen point 1 are converted into the electric  signals via piezoelectric element 2 and then delivered through the position detecting  pen. For such pen, the output of element 2 is supplied to one input terminal of operational amplifier 6 provided at voltage detector circuit 8 with the other input terminal earthed. At the same time, resistance 9 and capacitor 10 are connected in  parallel between output terminal 7 and the input terminal of amplifier 6, and the  signals of element 2 are detected by the current and through circuit 8. Thus, the induction of the external noise is prevented in case the signal transmission line is increased between circuit 8 and element 2, accordingly increasing the S/N for the output signals.

Title: Measuring device for reflection factor of mirror
Inventor: IIDA WATARU
IPC: G02B5/08
Filed: 1986-03-20
Abstract: PURPOSE:To surely detect the deterioration of a laser light reflecting mirror by measuring the reflection factor of the mirror by means of the temperature due to heat accumulated in the mirror itself. CONSTITUTION:When the mirror 5 is deteriorated and its reflection factor is reduced, the heat of laser light is accumulated in the mirror 5 and the temperature of the mirror 5 is raised. At the reduction of the reflection factor, the temperature of the mirror 5 is increased up to 70-80 deg.C. Thereby, the temperature of a heat discharging fin 6 fitted to the back of the mirror 5 is also increased and a shape memory alloy 7 fitted to the fin 6 detects the temperature change and changes its shape. The change of the shape memory alloy 7 is detected by a proximity switch 8 to measure the reflection factor of the mirror 5. Thus, the deterioration of the mirror can be determined by detecting the temperature of the mirror.

Abstract: PROBLEM TO BE SOLVED: To eliminate errors by means of a simple processing by inverting inputted first LUT(look-up table) data and re-arranging second LUT data in the reverse order, so as to execute a color conversion processing when a color mode is an RGB mode. SOLUTION: Color signal data of a first color system is inputted to a color coversion processing circuit 6. When the color mode is an RGB mode, the input LUT data processing part 34 of CPU 5 inverts input LUT data inside an input LUT data storing part 33 and sets it in an input LUT circuit 25. A 3DLUT data processing part 36 re-arranges 3DLUT data inside the input LUT data storing part 35 in a reverse order and sets is in a 3DLUT circuit 26. An interpolation coefficient calculating part 40 sets an interpolation coefficient in the 3DLUT circuit 26. The 3DLUT circuit 26 converts color signal data of the first color system, which is read from the input LUT circuit 25, into one corresponding to the colors (C, M and Y) of a second color system.

Title: Beta ray scintillation detector
Inventor: IKETANI YOSHIFUMI
IPC: G01T1/20
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To restrain increase of noise level and reduce the cost of manufacture even if a sensitive area is increased at the time of β ray measurement. SOLUTION: A β ray scintillator 1 emits fluorescent light generated by the βrays incident on a sensitive surface to optical guide means 3, which leads the fluorescent light a pin photodiode 4, which outputs a detection signal SP after the fluorescent light is received by a light receiving surface. In this case, the means 3 has an emission surface with an area corresponding to the light receiving area of the diode 4 irrespective of the sensing area of a β ray scintillator 2. The same one as the diode 4 can be used irrespective of the sensitive area so that the noise level can be made constant substantially even if the sensitive area is increased, thereby assuring the construction of a β ray sintilation detector of low cost type excellent in its noise characteristic.
