Title: Multi-layered reflection mirror
Inventor: MORIMO MAKOTO
IPC: G02B5/28
Filed: 1986-04-14
Abstract: PURPOSE:To improve heat resistance and moisture resistance by alternately laminating thin films of ZnS and SiO2 on a reflecting substrate, and depositing a protective film atop the alternate layers and subjecting the films to a calcination treatment at a specific temp. CONSTITUTION:The thin films of ZnS and SiO2 are alternately laminated on the reflecting substrate and after the protective film is deposited atop the alternate layers, the films are subjected to the calcination treatment at 450-520 deg.C. For example, a reflector 1 is a reflection mirror for a halogen lamp consisting of hard glass and forms a concave face 2 having a paraboloidal shape of revolution expanded at one face. A light source 3 is provided to the central position of the concave face 2. The multi-layered films 4 are the alternate layers of 1/4l optical film thickness consisting of 22 layers of ZnS-SiO2 and are formed by depositing a high-refractive index material consisting of ZnS, designated as H, and a low-refractive index material consisting of SiO2, designated as L, alternately 6 times, total 12 layers, further adding one layer of H thereto, further laminating and depositing L and H alternately 4 times total 8 layers, and depositing 2 layers of L as the protective film on the uppermost layer thereof. The moisture resistance of the multi-layered films is thereby improved without spoiling the heat resistance thereof.

Filed: 1987-04-09
Abstract: PURPOSE:To achieve a higher durability of a quartz window, by building a new shield layer in an nuclear reactor to prevent corrosion of the quartz window by acid. CONSTITUTION:A pair of electrodes 5 are imbedded at both ends of a carbon furnace 2, in which 2 a carbon tube 1 is placed.

Title: Image forming device
Inventor: HARADA KENTARO
IPC: H04N1/38
Filed: 1985-04-22
Abstract: PURPOSE:To specify and erase an optional part of an original image and to facilitate specifying operation by moving spot light with which the original image is irradiated and specifying the erasure range while varying the moving speed of the spot light according to the operation of operation keys. CONSTITUTION:The spot light with which an original platen 2 is irradiated from a spot light source provided opposite the original platen 2 is moved to specify an erasure range. For example, operation keys 30a-30d are operated to move the spot light to points S1 and S2 on an original G and an erasure range specifying key 30f is operated to specify a rectangular area which has points S1 and S2 as diagonal points as an erasure range. The operation keys 30a-30d consists of movable contacts 171, 172 and 173, and a movable element 174; when the movable element 174 is operated lightly, the contacts 171 and 172 contact each other to set a low-speed driving mode and when the movable element 174 is operated strongly, the contacts 171, 172 and 173 all contact one another to set a high speed driving mode. Consequently, the spot light is moved to a desired position efficiently.

Title: Constant current switching circuit
Inventor: YUSA MASAAKI
IPC: H03K17/04
Filed: 1987-04-08
Abstract: PURPOSE:To switch a large output current at a high speed with low current consumption by providing a speed compensating circuit which is controlled with an input signal and grounds the base of a reference transistor(TR) when the TR is turned off. CONSTITUTION:When an 'L' input signal VIN is supplied to an input circuit 15 and the speed compensating circuit 19 through an input terminal 11, the output sides of the circuits 15 and 19 turn off. Consequently, the potential at a node N11 is raised with a constant current I0 outputted from a constant current source circuit 14 and the reference TR 17 and output TRs 18-1-18-N turn on, so that output currents I11-I1N flow to output terminals 13-1-13-N. If the input signal VIN raises abruptly to 'H' in this state, the circuit 15 turns on and the constant current I0 flows to the ground side. At this time, a capacitor CS is discharged through the circuit 19 so that a current ip flows to the ground side. Consequently, the reference TR 17 and output TRs 18-1-18-N constituting a current mirror circuit turn off instantaneously.

Abstract: PURPOSE:To facilitate single-crystallization of a large area which has no crystal grain boundary or local single-crystallization of a required region only in a short time by a method wherein a laser beam is deflected and controlled by an acoustic optical device and an amorphous insulating substrate is subjected to laser beam annealing. CONSTITUTION:A beam from a laser oscillator 1a is directly introduced into an acoustic optical device 3a by a total reflective mirror 2a and the beam is deflected with a high speed to the direction Y with a deflection angle thetaa controlled by the acoustic optical device 3a to become a quasi-linear laser beam and converged onto the surface of a sample 5a such as a semiconductor substrate on an X-Y stage 6a by a flat field lens 4a. The width of the quasi-linear laser beam is determined by the distance Ha between the lens 4a and the surface of the sample 5a and the deflection angle thetaa. As high speed scanning is not necessary to the direction X, the scanning to the direction X is performed by the X-Y stage 6a. With this constitution, single-crystallization of a required large area can be realized. Moreover, if an optical chopper is provided between the laser oscillator and the total reflective mirror and the frequency of the optical chopper, the deflection angle and the distance between the flat field lens and the surface of the sample are regulated, only a local single-crystallization of a required region can be realized.

Abstract: PURPOSE:To obtain a uniform quantization accuracy over the entire signal level range of a video signal by providing a weighting means to an A/D converter of a video signal in an image pickup device or the like, and applying different weighting to each quantization step of A/D conversion. CONSTITUTION:A ladder resistance circuit 1 in an A/D converter such as N-bit full parallel comparison system consists of 2N sets of resistors. Moreover, the potential Vref across the ladder resistor is controlled variably by using a control signal of a gain control circuit GCC. Then ladder resistances R1, R2...R2N are determined to supply an equal quantization step DELTAV after nonlinear processing such as gamma characteristic or white level compression characteristic. Digital outputs D0, D1...DN-1 from a decoder circuit 3 obtained in such a way are subject to nonlinear processing, then no new gamma correction circuit or white level compression circuit is required. Thus, the resistance values of the ladder resistor circuit of the A/D conversion are made correspondent to the nonlinear characteristic in such a way, then almost uniform quantization accuracy over the entire signal level range of the video signal is obtained.
