Title: Silver halide photographic sensitive material
Inventor: SATO KOICHI
IPC: G03C1/76
Filed: 1988-01-30
Abstract: PURPOSE:To reduce color turbidity and to improve color reproducibility of a silver halide photographic sensitive material by regulating a ratio of relative color developing speed between two couplers having fast-to diffusion characteristics to a specified relation with a capacity for decelerating (deactivating) an oxidized body of a color developing agent in a non-sensitive intermediate layer. CONSTITUTION:A compd. capable of deactivating an oxidized body of a color developing agent is contained in a non-sensitive intermediate layer, and a relative color developing speed ratio k1/k2 (wherein k1 is a smaller color developing speed, and k2 is a faster color developing speed) between two fast-to diffusion couplers contained in each two photosensitive silver halide emulsion layers adjacent to the non-sensitive intermediate layer, is regulated to >=0.25 and <=1, and a product of k1/k2 with Sc (capacity for deactivating an oxidized body of a color developing agent in the non-sensitive intermediate layer) is regulated to >=0.2. Preferred compd. for deactivating the oxidized body of the color developing agent is hydroquinone derives. Thus, color turbidity of a silver halide photographic sensitive material is prevented and the color reproducibility is improved.

Filed: 1982-02-10
Abstract: PURPOSE:To obtain sharp optical demultiplexing characteristics easily by giving a slanting angle between two facing planes that makes multipath reflection of light and changing successively angle of incidence with the number of times of reflection. CONSTITUTION:A slanting angle theta is given to two facing planes A and B of a transparent plate 1 that leads input signal light making multipath reflection, and the planes are not parallel. Branched output signal light is led by a prism 2.

Title: Manufacture of semiconductor device
Inventor: KAWAMURA EIICHI
IPC: H01L21/68
Filed: 1990-01-31
Abstract: PURPOSE:To sense a malfunction on the surface of a substrate before a pattern is transferred and to cope with it by sucking the substrate to a vacuum chuck having an uneven part on its surface, measuring the flatness of the entire surface of the substrate, once removing the substrate from the chuck if a nonflat part is sensed, and resucking it after its position is deviated. CONSTITUTION:A substrate 1 is sucked on a vacuum chuck 3 by predetermined conveying means, and secured to a predetermined position on the chuck 3. If a foreign matter 4 exists between the rear surface of the substrate 1 and the protrusion of the chuck 3, a protrusion responsive to the size of the matter 4 is formed on the substrate 1. Accordingly, a chip region different in height from other chip region is formed on the substrate 1. If a protrusion is detected on the substrate 1, a defocusing is eliminated when a pattern is thereafter transferred. The matter 4 for causing the protrusion to be formed on the substrate 1 is contained in the recess of the chuck 3, and the flatness of the substrate 1 is recovered.

Title: Dimming circuit for light source of copying machine
Inventor: IWASAKI AKINORI
IPC: H05B37/02
Filed: 1986-01-31
Abstract: PURPOSE:To prevent the generation of unevenness in the image density due to the unevenness of light emission caused by the variation of power supply voltage by applying the output of a differential amplifier circuit to a thyristor dimming circuit whose output side is connected to a light source to attain negative feedback. CONSTITUTION:A difference between a DC voltage obtained by converting the output of the thyristor dimming circuit with an AC/DC conversion circuit 7 and a voltage generated from a reference voltage generating circuit 8 is amplified by a differential amplifier circuit 9 and the output of the circuit 9 is inputted to the circuit 6 to attain negative feedback. When the output voltage of the circuit 6 is desired to be set to 70V, e.g., the output voltage of the circuit 8 is set to 7V because the output of the circuit becomes 7V. When the power supply is changed and the voltage of the circuit 6 is boosted >=7V, the circuit 9 negatively amplifies the difference between the outputs of the circuits 7, 8 so as to drop the output voltage of the circuit 6. Consequently, an always constant voltage is impressed on a halogen lamp 10 even if the power supply voltage is varies, so that the quantity of light can be maintained at a constant value.

Title: Noise eliminating circuit of video signal
Inventor: OZAKI HIDETOSHI
IPC: H04N5/21
Filed: 1984-02-10
Abstract: PURPOSE:To eliminate only noise of a video signal without giving deformation to the sudden rise and fall parts and the detail part of the incoming video signal by having the subtraction and mixture of a high frequency component to the video signal as a subtracting signal only in a period when the high frequency component of the video signal is kept within a prescribed level range. CONSTITUTION:The video signals supplied to a terminal 1 are supplied to a mixer 2 and an HPF3. The HPF3 extracts the high band component of the video signal and supplies it to a wind comparator 6 and a switch circuit 7. The comparator 6 has the 1st and 2nd reference voltages V1 and V2 and delivers the control signals of H and L levels when the input voltage is lower than V1 and higher than V2 and set between V1 and V2 respectively. Both V1 and V2 are set at an approximately equal level to the limiter value of a conventional circuit. The circuit 7 delivers the signal given from the HPF3 as it is when the control signal is set at an L level and cuts the signal from the HPF3 when the control signal is set at an H level. Thus the subtracting signal is extracted out of the circuit 7 and supplied to the mixer 2.
