Title: Monitor device
Inventor: FUJII MASAAKI
IPC: G01N21/47
Filed: 1980-03-19
Abstract: PURPOSE:To reduce reflected light on the surface of a sight glass, by setting the incident light of a light source to the same angle as a polarization angle and by providing a polaroid filter on the light source surface to permit only an oscillating component in the light of the light source to pass through. CONSTITUTION:Out of light Ii incident to sight glass 21 from projector 10 a part of refracted light Id, which is incident into sight glass 21, is reflected by content 22 and permeates sight glass 21 again and is caught by TV camera 30 to monitor the state  of contents 21. At this time, the fitting position of polaroid filter 13 mounted on projector 10 is set so as to permit only the light having oscillating component of the e lectric field parallel with the incident face to pass through filter 13, and oscillation components of the electric field orthogonal to the incident face are eliminated, and incident angle psi is set to polarization angle E to eliminate the influence of  the reflection light on the surface of sight glass 21. The surface reflection in the  sight glass is reduced to obtain the monitor device of a high S/N ratio.

Title: Semiconductor device
Inventor: NAKAGAMI SHUICHI
IPC: H01L21/3205
Filed: 1985-02-25
Abstract: PURPOSE:To achieve high speed operation, by spreading the low-melting metal layer all over the selected portions of the wiring layer formed with thin conductive film. CONSTITUTION:On the silicon substrate, the lower insulative film 15, the Al1 wiring layer 16, the protection film 17, the interlaminar insulating film 18, the Al2 wiring layer 19 and the passivation film 20 are formed. This passivation film 20 is subjected to etching by applying the photoresist 40 to the mask corresponding to the output signal wire 19A. On the whole surface, Cr, Cu and Au are thinly deposited in turn to form a metal film 42. A portion of this metal film is stuck to the upper surface of the output signal wire 19A, on which the photoresist forms a pattern. By applying this pattern to the mask, the metal film 42 is subjected to etching, and the lower film 32 is formed. The metal mask 44 provided with a window 46 facing to the lower film 32 is set right over the silicon substrate 1, and the soldering layer 45 is deposited on and near the lower film 32. By heating, the soldering layer 45 melts and sticks to the surface of the lower film 32 to form the low-melting metal layer 30 whose vertical cross section is a half-circle. Thus, the electric resistance of wiring can be reduced without widening the wiring layer, so that the voltage drop is restrained and the operation margin can be increased.

Title: Recording and reproduction method for video signal
Inventor: KOBAYASHI MASAAKI
IPC: H04N5/92
Filed: 1979-03-23
Abstract: PURPOSE: To increase the S/N of recording signal, by taking the point apart from the modulation carrier frequency by a given frequency as the maximum point of frequency characteristics of recording signal.  
     CONSTITUTION: The luminance signal included in video signal from the input terminal 1 is fed to the adder 5 via LPF2 and FM modulator 3, and on the other hand, the carrier chroma signal is converted into low band conversion carrier chroma signal via BPF 6 and fed to the adder 5 via the emphasis circuit 10. The frequency characteristics of the circuit 10 is set as follows: That is, the center of the frequency characteristics is taken as the low band conversion chroma carrier frequency and set is made that the point apart by a given frequency, i.e., the frequency of the main component of noise of the tape head system 11 is the maximum point of the emphasis characteristics. Further, in case of reproduction, the frequency characteristics of the de-emphasis circuit 16 is taken as the opposite characteristics as the circuit 10. Thus, the S/N can be increased for the carrier chrominance signal. Further, the same can be made as to luminance signal.

IPC: G02B7/32
Filed: 1986-02-18
Abstract: PURPOSE:To obtain a light detector wherein the dynamic range of a photocurrent is suppressed low and noise is reduced, by providing a light blocking layer having a light previous window, of which the width is successively reduced from the central part thereof toward the end part thereof where at least one of electrodes is present, on a P-type high resistance layer. CONSTITUTION:A P-type high resistance layer 2 is formed to the entire surface of a high resistance N-type substrate 1 and electrodes 3, 3' are provided to two opposed end parts of said P-type resistance layer 2, and a low resistance N-type layer 4 and an electrode 5 are provided to the back surface of the substrate 1. A light irradiating window 12 is formed to the light blocking layer 10 so as to successively become narrow from the central part thereof toward one electrode. By this method, the optical noise from a part not irradiated with signal light can be reduced. The quantity of light increases at the time of close range but the dynamic range of a photocurrent can be suppressed low by reducing the size of the light irradiating window.

Title: Toner replenishing device for developing of copying machines and others
Inventor: FURUICHI YASUSHI
IPC: G03G21/00
Filed: 1978-03-24
Abstract: PURPOSE:To end copying of a required number without stopping copying on the way at the continuous copying despite detection of a minimum developer concentration by providing a minimum developer concentration detecting part, a copying operation disabling circuit and a continuous copying holding circuit. CONSTITUTION:While not in continuous copying, the output of a set counter 15 is H level and therefore as toner concentration lowers and when an output is emitted from a minimum developer concentration detecting part 2 where there is no toner in the toner replenishing part, then an AND circuit 13 opens to apply a signal to a copying operation disabling circuit 4, thus causing the apparatus to stop. Next, when there is no replenishing toner at the continuous copying, the signal is emitted from the minimum concentration detecting circuit part 2, but the output of the set counter 15 is L level and therefore the AND circuit 13 does not open and the continuous copying continues in that state. The AND circuit 13 opens only when the continuous copying ends and the output of the set counter 15 becomes H, then the  copying operation disabling circuit 4 operates to disable the copying.
