Title: Preparation of silver halide flat platelike emulsion under existence of polar aprotonic solvent and/or alocohol
Inventor: ANHERU MIRAN
IPC: G03C1/07
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a new manufacturing method for a silver halide photographic emulsion containing platelike silver halide grains showing high aspect ratio, high flatness and high homogeneity. SOLUTION: Silver salt and halide salt are dissolved by adding silver salt of a quantity for obtaining 0.01-1M concentration and halide salt of a quantity for obtaining concentration 1-10 times of the mol concentration of silver salt in a reaction container containing a polar non-protonic solvent. In order to form twin platelike nuclei, a protonic solvent is added in the reaction container. In order to obtain the weight ration of water to (non-) protonic solvent of 40:60 or less in the reaction container, protective colloid is added together with protonic solvent or separately or with a mixture of protic or aprotonic solvent to stabilize the twin platelike nuclei colloidally. The obtained emulsion crystal is condensed or decanted, and subsequently washed and re-dispersed, or subjected to the application of dialysis or ultrafilteration.

Title: Driving method for solid-state image pickup element
Inventor: NAKAI TOMOMICHI
IPC: H04N5/335
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of flickers on a reproducing screen when the light emission cycle of illumination does not match with the image pickup cycle of an image pickup element. SOLUTION: Corresponding to a light source for emitting light in 1/100 sec cycle, the operation timing of the image pickup element for repeating an image pickup operation by 1/30 sec cycle is set at every three cycles. In a first period V1, the timing of frame transfer is quickened by 1/300 sec to the timing of vertical scanning. In a second period V2, the timing of the frame transfer is quickened by 2/300 sec. Thus, the first and second periods V1 and V2 match with the triple of the light emission cycle T1 of the illumination and a third period V3 matches with the quadruple of the light emission cycle T1 of the illumination. Since the light emission state of the illumination is uniformized in each of the periods V1-V3, in image signals obtained by the image pickup operation in the period, the dispersion of a level for each vertical scanning period is eliminated.

Abstract: PURPOSE:To improve the picture quality by selecting the capacity of a memory for generating a synthesized video signal as a frame normally and selecting the memory capacity for one field in converting the horizontal frequency of the synthesized video signal into twice so as to double the number of horizontal periods to be written with the data of a synthesized video signal. CONSTITUTION:Since the capacity of a memory section 7 is one frame normally, there is no difference of picture quality at animation picture and still picture. In changing the horizontal frequency of the synthesized video signal into twice as the normal frequency, the memory capacity 1 is selected as one field, lines E1, E3, E5, E7, E9... are stored in the memory when even number fields are written, a line 02' is synthesized from lines 02, 03 in writing an odd number field, lines 04', 06', 08'... are synthesized and stored in the memory. In doubling the write horizontal period number of the synthesized picture, a mode switching control input 5 is used to change over a memory address generating circuit for a write control section 6 and a read control section 8 thereby operating the processing above.

Title: Light emitting door window panel structure
Inventor: MURAHASHI KATSUHIRO
IPC: B60Q11/00
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To improve a light utilization factor of a light source by forming a through hole in the lower part than a waist line of a door window panel, housing the light source in this through hole, and sealing the inside of the through hole by blocking up both sides of the through hole by panels. SOLUTION: A light source A is arranged in this through hole 5 by forming the circular through hole 5 in a lower side position than a waist line W in the longitudinal central vicinity of a door window panel 1. The inside of the through hole 5 is sealed by blocking up both sides of the through hole 5 by transparent panels 6, 7 mutually installed on the door window panel 1. Therefore, a beam L of light emitted from the light source A in the through hole 5 emits the light over a light distribution range H of the upper side end part 4 by entering the door window panel 1 in a state where a light distribution angle θ is expanded by the circular arc-shaped upper side inside surface 5a of the through hole 5. Thus, a light utilization factor is enhanced since the beam L of light directly enters the door window panel 1 from the light source A.

Title: Optical disk device
Inventor: IWATANI YASUYUKI
IPC: G11B20/18
Filed: 1989-02-02
Abstract: PURPOSE:To improve the data reproducing ability by using a data demodulation circuit which demodulates data with a reproduction signal undergone the waveform shaping based on a synchronizing signal and produces an error detecting signal when an error of the reproduction signal is detected and an error detecting/correcting circuit which corrects the error of the demodulated data based on the error detecting signal. CONSTITUTION:A waveform shaping circuit 4 shapes the waveform of the signal reproduced from an optical disk, and a synchronization detecting circuit 5 detects a synchronizing signal SYNC out of the reproduction signal undergone the waveform shaping. A data demodulation circuit 6A demodulates the data G out of the reproduction signal undergone the waveform shaping based on the signal SYNC. In case an error of the reproduction signal is detected, an error detecting signal H is produced. Furthermore an error detecting/correcting circuit 7A corrects the error of the data G which is demodulated based on the signal H. Thus it is possible to detect all error positions and to improve the data reproducing ability.
