Title: High pressure reactor
Inventor: MIURA MICHIO
IPC: B01J3/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To improve thermal performance, to avoid corrosion of a pressure- resistant part, to decrease adhesion of scales and to reduce cost. SOLUTION: A high pressure reactor consists of a pressure-resistant container 1 consisting of an outer cylinder 1a and lids 1b and 1c and provided with inlets and outlets 5-9, an intermediate cylinder 2, an inner cylinder 3, a sealing material 4 for a gap 12, or the like. In this apparatus, a high pressure water is fed from a water inlet 5 and a liq. after reaction is cooled in a cooling part 13 and it is discharged from a water outlet 6 and it is heated again in a heating tool 22 and oxygen is fed and the high pressure water at the supercritical temp. is fed into a reaction part 11 from a water refeeding inlet and, at the same time, waste liq., or the like, is fed and oxidative reaction is performed to decompose hardly decomposable org. substances, or the like, under supercritical environment.  It is possible to obtain a long cooling part 13 and good recovering rate of heat of reaction, to avoid corrosion of the outer cylinder as the waste water does not enter into the outside flow path 10, to be unnecessary to use a highly corrosion-resistant material, to cool and liquify a fluid after reaction, to adsorb and dissolve scale ingredient and to take out it to the outside and to decrease adhesion of the scale on the intermediate cylinder 2.

Abstract: PURPOSE: To prevent the generation of noise by forming a primary groove connected to a discharge side and a secondary groove connected to a suction side and by connecting the end to the primary groove when an ineffective engagement point between a drive gear and driven gear is located on the center line.  
     CONSTITUTION: When an ineffective engagement point 10 between a drive gear 1 and a driven gear 2 is located on the center line, a primary groove 15 as well as a secondary groove 18 are respectively formed. The primary groove 15 connects the first figure Sa to a discharge side 4 while the secondary groove 18 connects the second figure Sb to a suction side 5. An edge portion 17 is provided in the primary groove 15, in order to connect the first figure Sa to the discharge side 4, when the primary groove 15 is disengaged from the first figure Sa. This construction maintains such a fluid pressure as not abnormally high in a part of an enclosed portion, and can gradually reduce the fluid pressure, thereby preventing the generation of noise due to fluctuation of the fluid pressure in the enclosed portion.

Title: Combination mechanism of rack and pinion
Inventor: NAMIKI AKIRA
IPC: F16H55/08
Filed: 1979-08-20
Abstract: PURPOSE:To restrict a displacement caused by a slight rotation of a rack and its vibration by selecting the radius of a helical rack, a distance from the axis to the tooth end, a helix angle of the tooth and pressure angle to satisfy a specific expression. CONSTITUTION:This rack and pinion mechanism is applicable for a power steering mechanism in an automobile. When a helical gear 2 with a helix angle beta and a pressure angle alphan feeds in mesh a pinion (not illustrated) in the direction A and a rack in the direction B, a normal plane pressure Pn at a contact point S1 where the helical gear comes in mesh with a spiral gear not illustrated in the drawing acts in the direction S1C1. Therefore, the moment C in the counterclockwise direction is generated. When the mesh comes to a contact point S3, the moment D in the clockwise direction is formed. By determining the configuration of the rack 1 so as to satisfy the expression (LK represents the radius of the rack 1 and RK represents the distance from the axis 0 to the tooth end.), the clockwise and counterclockwise moments may become equal so that the required purpose can be attained.
