Abstract: PURPOSE:To restrict expansion of wiring resistance due to increase in a disconnection part by providing a middle layer which is set to a specified value between a main wiring layer and a barrier layer which is laminated at this main wiring layer. CONSTITUTION:A middle layer 4 consisting of a specific resistance sigma3 and a film thickness of t3 is provided between a main wiring layer 5 of semiconductor device consisting of a laminated layer of a main wiring layer 5 of a specific resistance sigma1 and a film thickness of t1 and a barrier layer 3 of a specific resistance sigma2 and a film thickness of t2 and the specific resistance sigma3 and the film thickness t3 of the middle layer 4 are set so that the relation sigma1<sigma2<sigma3 and t1>t2>t3 are established. Since this middle layer 4 has a relatively large resistance, the amount of current flowing between a wiring layer 5 and a barrier layer 3 can be reduced. Thus, when the wiring layer is disconnected, a region where current flows from the barrier layer 3 into a disconnection layer, namely a region which is relatively away from the disconnected part, thereby relaxing current concentration around the disconnected part. It will restrict electromigration and increase in wiring resistance due to expansion of the disconnection part.

Abstract: PURPOSE:To facilitate the high-luminance illumination by installing both the filter which reflects the heat rays and transmits other rays and the filter which absorbs the heat rays and transmits other rays each in combination into the illuminating optical path given from the illuminating light source. CONSTITUTION:Filter holder 4 doubling the heat dissipating part is provided near light emitting system 3 comprising illuminating light source 1 and reflector 2. Then reflective filter A1 having an inclination of 45 deg. and the 70% infrared reflection factor each which reflects and eliminates thd infrared rays and then transmits other rays is installed on optical axis 7 of holder 4. Furthermore, absorption-type filter B having the 95% infrared absorption factor which absorbs and reduces the infrared rays and then transmits other rays is installed vertically to the optical axis. Thus for the light given from system 3, the infrared ray component is reflected by filter A1. And the light is branch-radiated to holder 4 to be dissipated. The rest of the infrared rays and other rays transmit through the filter and then illuminate information reading screen 6 through condenser lens 5. Thus the infrared rays are reduced for the transmitted rays which illuminate screen 6 to eliminate the scorching on screen 6. As a result, the lowering of the image resolution can be solved for the sensor even under the high-luminance illumination.

Abstract: PROBLEM TO BE SOLVED: To hardly generate electric deterioration of a joint main body by setting electric resistance of the joint main body made of a resin connected to a fuel hose made of a resin so that either of the volume resistivity or the surface resistivity is a specific value. SOLUTION: This resin joint is connected to a fuel house 12 made of a resin, an O-ring 28 is built in the inner circumferential wall of the pipe insert part 26 of a joint main body 24, and what is called, a quick joint is constituted. The necessary condition of the joint main body is that the electric resistance satisfies either of volume resistivity of 10<6> -10<10> Ω.cm or surface resistivity 10<6> -10<10> Ω. When the electric resistance of the quick joint exceeds the upper limit value, the electric resistance becomes excessively high, and hence static electricity generated inside the hose is difficult to move to a metallic pipe 22 through the quick joint 12.  In opposition, when the electric resistance is under the lower limit value, large current flow is generated between the contact part positions of the joint main body 24 and the metallic pipe 22 to be a static electricity eliminating route, and hence there is possibility to generate electric deterioration of the resin on the quick joint.

IPC: H03H11/18
Filed: 1986-04-24
Abstract: PURPOSE:To phase-shift an input signal by 90 deg. at high accuracy by setting both propagation functions so that the real number part of Z1/Z2 can come to zero where the propagation function of an input processing circuit and that of a feedback circuit are Z1 and Z2, respectively. CONSTITUTION:The output signal voltage of the input processing circuit 11 is supplied to the noninversion input terminal of an amplifier circuit 13, and the output signal voltage of the feedback circuit 14 is fed back to the inversion input terminal of the amplifier circuit 13. An equation 4 defines a phase difference theta between the input signal voltage Vin and the output signal voltage Vout. Inequalities 6 and 7 give necessary conditions where theta=+90 deg. and theta=-90 deg., respectively. As the equation 4 and the inequality 7 show, the phase difference thetabetween the input signal voltage Vin and the output signal voltage Vout is decided only by the ratio of the propagation function Z1 of the input processing circuit 12 to that Z2 of the feedback circuit 14. Accordingly, if the accuracy of the Z1/Z2 is maintained, the output signal voltage Vout precisely phase-shifted by 90 deg. from the input signal voltage Vin can be obtained.
