Title: Recording method
Inventor: OKA KENJIYU
IPC: G03G15/06
Filed: 1982-12-27
Abstract: PURPOSE:To obtain a good recording picture which is excellent in its discriminating effect by having a variable density difference in the picture density, and is always stable even if a state of electric discharge by a recording electrode is varied, by forming the first and the second latent images by impressing each different potential. CONSTITUTION:A latent image to be formed in the first low density, which is a negative image is formed by discharging the charge by the potential VL1 in accordance with a picture part by the first recording electrode 3 to a dielectric drum charged uniformly to Vs by the first scorotron charger 2. When the voltage impressed by the second scorotron charger 4 is set to a value which is higher than VL1 and lower than Vs to some extent, the unstable potential VL1 is corrected and charged to a stable constant potential VL2. Subsequently, the second latent image to be formed in a high density is formed by impressing the potential VL3 which is lower than VL2 to the second recording electrode 5. With respect to the potential Vs of this non-picture part, a composite electrostatic latent image consisting of VL2 and VL3 is brought to an inversion development by setting the development bias voltage Vb almost equally to the non-picture part potential Vs, or a little lower than it, by which a picture having a discriminating effect by a variable density difference is obtained.

Title: Semiconductor memory device
Inventor: NAKANO TOMIO
IPC: H01L27/10
Filed: 1982-12-29
Abstract: PURPOSE:To improve software error preventing effect by alpha rays, by constituting the cell part of a substrate by arranging a high concentration region directly below a high concentration region furthermore. CONSTITUTION:A semiconductor memory cell is formed on a P type substrate 10. A P<+> layer 12 and a P<++> layer 11 are provided directly below the cell. An N layer 13 is provided in the vicinity of the upper surface, and a depletion layer D is expanded. The thickness of the P<+> layer 12 is determined so that the depletion layer D is included in the P<+> layer 12 and does not reach the inside of the P<++> layer 11. Thus the width of the depletion layer is sufficiently reduced in the P<+> layer 12. In the P<++> layer 11, high concentration is suffificiently imparted without restricted by junction breakdown. The concentration ratio Nn/Np of electrons and holes can be sufficiently reduced in the P type substrate. By the synergistic effect, the thickness of a region, wherein field funneling phenomenon, by which an electric field is temporarily expanded under the depletion layer occurs, is largely reduced. Therefore, the number of electrons, which are induced by the input of alpha rays and absorbed in the N layer, is decreased, and the software error preventing effect due to the alpha rays is improved.

Title: Reciprocating compressor
Inventor: MIYAKE SHINGO
IPC: F04B39/00
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a reciprocating air compressor, with improved ease of assembly of piston into cylinder and enhanced wear resistance of piston ring at starting. SOLUTION: The outer diameter dimension of piston rings 17 before assembly to a cylinder 9 is made equal to, or smaller than, the inner diameter dimension of the cylinder 9 and, at the same time, materials are used so that the coefficient of linear thermal expansion of the piston rings 17 is greater than that of the cylinder. This enables the following. Under room temperature, the piston rings 17 are not in contact with the inner surface of the cylinder 9 as their outer diameter is smaller than the inner diameter of the cylinder 9. During operation, the outer diameter of the piston rings 17 becomes equal to the inner diameter of the cylinder 9 due to thermal expansion, allowing the cylinder 9 to slide.

Title: Coating liquid applying method
Inventor: SONE YASUSUKE
IPC: B05D1/26
Filed: 1989-09-05
Abstract: PURPOSE:To prevent the generation of unequal application in a curtain applying system by confining the contents of the org. solvents in coating liquids to <=5%. CONSTITUTION:The coating liquids 13 and 14 are run down and are applied on a web 10. Many additives, such as spectral sensitizing dyestuff, surfactants, and couplers, are added at need into photogaphic emulsions in the production of silver halide photographic sensitive materials. Some of these additives are hardly soluble in water and various org. solvents including alcohols, such as methanol and ethanol, are used. If, however, these org. solvents are used at a high ratio, the stability of the flowing down liquid film is drastically impaired in the curtain application and, therefore, the contents of the org. solvents in the coating liquids 13 and 14 are confined to <=5wt.%. The generation of the unequal application in the curtain application system is prevented in this way.

Title: Car door of elevator
Inventor: ITO NAOTO
IPC: B66B13/14
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To operate a locking device even when an accident occurs during power failure by providing the tip of an engaging plate with the locking device having a fastening tool for releasing engagement from the engaging plate when a car normally lands, if a landing door is opened/closed by being pushed by the engaging plate at the same time when a car door is opened/closed by a motor. SOLUTION: When a car lands in the range of normal landing in a elevator hall, a door motor is actuated and the door panel 4 of a car door is moved in an opening direction. The engaging roller of a landing door is pushed so as to open the landing door at the same time when the engaging plate 11 of the car door is moved together with the door panel 4 and the roller is rotated in a counterclockwise direction until coming into contact with a stopper 14. Then, the projection 20 of a fastening tool 18 is disengaged and since the downward movement of the tip of the engaging plate 11 is made free, the fastening tool 18 is caused to be in a lock releasing state. Thus, since locking of the car door is not released when the car stops in a position in which passengers cannot escape during closing of the car door, that is, when the car stops in a middle point between floors, opening of the car body by the passengers is prevented.
