Title: Preparation of photographic developer
Inventor: MAIKERU RITSUJIUEI
IPC: G03C5/26
Filed: 1994-04-13
Abstract: PURPOSE: To enable the use of a developer not oxidized with air by electrolyzing an aq. medium contg. a developing agent precursor compsn. which forms or releases a silver halide developing agent on electrodes when the medium is subjected to an electrolysis. CONSTITUTION: Two pieces of cooperative elements 2 and 3 of a battery 1 are fastened together by means of a screw and are assembled, by which a battery body 4 is formed. A fibrous conductive material, for example, steel, is packed into this battery body 4. The battery 1 is immersed into the developer precursor soln. and the liquid is pulled up from take-out port and taken out. When the electrolysis is effected simultaneously by impressing voltage of, for example, 2 to 3 volts, the resulted liquid crystal is an active developing soln. The initial current until the specified state is maintained is usually discarded. This state arises extremely rapidly. The battery 1 is taken out of the developer precursor compsn. and water is applied thereon.  The developing agent remaining in the battery 1 is otherwise moved to a filter element 8 where the developing agent is oxidized by the air or cathode.

Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To easily form a liquid crystal arrangement which has a wide viewing angle and is hard to suffer breaking of alignment in a liquid crystal display device holding a liquid crystal with spontaneous polarization between substrates. SOLUTION: A counter electrode 13 is formed with two nesting comb shaped electrodes 13a, 13b and its rubbing alignment treatment is carried out in the longitudinal direction of the teeth of the comb shaped electrodes 13a, 13b. In the case a liquid crystal material is subjected to a phase transition from a nematic phase to a chiral smectic C phase, a positive DC voltage is applied between pixel electrodes 5 and one of the comb shaped electrode 13a and a negative DC voltage is applied between pixel electrodes 5 and the other comb shaped electrode 13b. Thereby a liquid crystal arrangement having smectic layers bent horizontally with respect to the surface of the substrate is easily realized.

Title: Memory read device
Inventor: KANEKO MASAHIDE
IPC: G11C16/06
Filed: 1984-04-13
Abstract: PURPOSE:To obtain a stable data output by fixing a bit line to the 3rd potential for a prescribed period before a word line is charged so as to decrease the access time. CONSTITUTION:Every time a change in the address signal is detected, the potential of the selected bit line is fixed to the 3rd potential. The 3rd potential is a potential nearly intermediate between the 1st potential discriminating the memory information of a memory transistor (TR) as ''1'' by a sense amplifier and the 2nd potential discriminating it as ''0''. The change in the address input signal selects the bit line 8 of the memory TR3 by a Y decoder 4, the voltage of the word line 7 is increased with a delay of 40-100 nano sec, and the memory TR is driven. When the bit line 8 changes from ''0'' to ''1'', since the bit line is at the 3rd potential before the word line 7 is charged, the access time is 1.5 and when the level of the bit line 8 changes from ''1'' to ''0'', the access time is 1.0 and a stable data output is obtained.

Filed: 1983-04-28
Abstract: PURPOSE:To supply a small current high voltage at a high response speed and to prevent arc breakage and spatter by providing a main power source which controls low voltage large current and an auxiliary power source for maintaining the arc which controls high voltage small current in a power source for welding. CONSTITUTION:A power source 3 for welding is provided with a transistor (TR) 4-1 for a main power source which supplies the low voltage large current in the stage of welding and a transistor (TR) 4-2 for an auxiliary power source which supplies the high voltage small current in the negative resistance region of arc current. The voltage of a welding wire 1 decreases upon starting of an arc and therefore the output from the TR 4-2 having the high voltage increases sharply and the current detected by a current detector 8 approaches the set value of a setter 15 by which the output from an error amplifier 14 is decreased. When the output (a) from the amplifier 14 is made smaller than the output (b) from an error amplifier 10, the voltage at the point (c) is equal to the voltage at the point (a). The width of the pulse to be impressed on base of the TR 4-2 is then controlled by the output voltage from the amplifier 14. The TR 4-1 is controlled in accordance with the set value of a current setter 11 so that the current on the wire 1 is increased.

Title: Optical disk player

IPC: G11B7/08
Filed: 1985-04-10
Abstract: PURPOSE:To increase accuracy of assembling by moving converged light of a light beam emitted from an optical pickup on a line connecting the center of axes of two motors. CONSTITUTION:Outermost circumference of a VLP disk 7 is nearly conformed to outer circumference of a turntable 10 for CD. When the motor for CD is placed obliquely front or back of a motor for VLP, lateral width l3 from the center OV to left end of a CD disk 8 is shortened by about 48mm. An optical pickup 11 moves parallel to a line connecting the center of two turntables 9, 10, and converged light 13 emitted from an objective 12 moves on a line connecting the centers OV, OC of two motors. As the disks are of the same reflection type and signals are recorded in pitlike form, reproduction is possible by the same optical pickup, and the distance of moving of the optical pickup is limited to the range in which the VLP disk can be reproduced. Thus assembling is very easy, and accuracy can be improved easily.
