Title: Method for stabilizing image quality of photoreceptor
Inventor: AOKI MINORU
IPC: G03G21/00
Filed: 1982-01-07
Abstract: PURPOSE:To stabilize the image quality at working frequencies of necessary minimum, by operating an image quality stabilizing system when a temperature change of more than a prescribed range is detected at the photoreceptor. CONSTITUTION:It is so arranged that electric potentials at the dark part and the light part are kept constant, by changing the charging current and the amount of the exposed light depending on the temperature of a photoreceptor as shown in figures. To always obtain the shown relations, the density variation is measured by detecting the reflectance factor of a latent image corresponding to a reference pattern and the density variation is fed back to the power source, charger, and developing bias power source. In this case, the feedback is performed by operating an image quality stabilizing system only when the temperature of the photoreceptor changes by more than a prescribed value, because the primary factor which changes the image density of parts other than the photoreceptor changes at time intervals longer than those of temperature change of more than a prescribed value. Therefore, the time required for copying is shortened, the toner can be used effectively, and the load on the device can be reduced.

Title: Flexible printed wiring board with bump and its manufacture
Inventor: YAMAOKA SEIICHI
IPC: H05K1/02
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To obtain a flexible printed wiring board which prevents troubles in which a bump part is cut and removed due to a vibration or the like when a product is transported or used, by a method wherein the bump part whose bump bonding force is at a specific value or higher is used so as to be soldered to a terminal or the like. SOLUTION: When the shape of an opening hole 1 for a bump part is contrived, a bump bonding force can be increased even in a range in which the diameter of the bump part is limited. The shape of the opening hole 1 is contrived, in such a way that the diameter of the opening hole in an insulating surface is smaller than the diameter of an opening hole in an interface with a circuit conductor 4. Consequently, the bump bonding force can be set at 50 g or higher. A flexible printed wiring board having the bump bonding force is used, and the bump part is soldered to a terminal or the like. Then, the trouble where the bump part is cut due to a vibration or the like will not be generated.  At this time, rather than not having the diameter of the opening hole 1 reduced gradually to be a taper shape toward the insulating surface, the diameter of the opening hole in the insulating surface is made smaller than the diameter of the opening hole in the interface with the circuit conductor 4 to be step-shape toward the insulating surface. As a result, the bump welding force is stabilized.

Title: Optical recording medium
Inventor: ARAKAWA SEIICHI
IPC: G11B7/246
Filed: 1988-01-08
Abstract: PURPOSE:To provide an organic dye material superior in resistance to light, solubility, molecular light absorbing coefficient, reflectance, and to obtain an optical recording medium superior in reliability and mass productivity, by adding a specific squarylium dye to a recording layer. CONSTITUTION:A recording layer of an optical recording medium contains a squarylium dye shown by a formula (1). In the formula, R1, R2 represent alkyl, and R3 represents hydrogen or alkyl. As the substituent introduced to the squarylium dye, every alkyl group can be used, but especially the use of a t-butyl group for R2 results in a high effect. The squarylium dye is synthesized through the following four steps of reaction: a cyclization reaction for synthesizing a quinoline having R2, the introduction of R3, an addition of R1 to an N- position, and the production of the squarylium dye by the condensation of quinoline and squaric acid. The use of the alkyl-substituted squarylium dye as a recording material remarkably improves solubility, reflectance, etc., and enhances productivity, optical characteristics, etc.

Title: Operation method of nuclear power plant and nuclear power plant
Inventor: ASAKURA YAMATO
IPC: G21D1/00
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To hold the concentration of a radioactive corrosion product low by controlling Ni concentration of water supply or reactor water in each operation cycle. SOLUTION: An Fe injection tank 11, an Ni injection tank 13, and a control part 12 for controlling Fe concentration and Ni concentration are provided. Production of Ni is controlled by increasing Fe concentration supplied to a water supply system by the control part 12 in a first cycle of the plant in which much elution of Ni exists. In a second cycle and thereafter Fe concentration of water containing Fe water-supplied from the Fe injection tank 11 is regulated by the control part 12, a production (elution) amount of Ni is increased by regulating Ni concentration of water containing Ni water-supplied from the Ni injection tank 13, an Ni adhesion amount is controlled so as to optimum in any cycle.  Thus, in the case where much Ni elution exists, a Fe-part is supplied, and in the case where remarkably less Ni elution exists, rational operation can be performed since Ni is prevented from becoming less.

Filed: 1986-01-09
Abstract: PURPOSE:To enable sufficient lubrication and to aim at enhancing the reliability of a thrust bearing, by forming an oil passage in a crankshaft, boring through the latter to extend between both ends of the crankshaft, and by enabling lubrication oil to feed the slide surfaces of a shaft hole and a thrust bearing. CONSTITUTION:On compressing operation, discharge gas flows into a space 47b in a shell through a communication hole 46, and a high pressure atmosphere having a pressure equal to the discharge pressure of the discharge gas is established in the space 47b. Accordingly, the discharge pressure effected in the space 47b causes lubrication oil 48 reserved in an oil sump 42a to ascend, as shown by the single line arrows, through an oil hole 19 boring through a crankshaft 17 to extend between both ends of the latter. Therefore, the oil flows through oil holes 20, 21 and an oil groove (which is not shown) to smoothly and sufficiently lubricate the mated slide surfaces of a swingable scroll shaft 8 and an eccentric hole 18 in the crankshaft 17, and the mated slide surfaces of inner and outer peripheral surfaces of a shaft hole 16 in a body 13 and the crankshaft 17, the surface 15 of a thrust bearing, etc., thereby it is possible to prevent the compressor from being seized and to enhance the durability of the compressor.
