Inventor: JINGU TOSHIHIRO
IPC: B41J11/50
Filed: 1988-09-16
Abstract: PURPOSE: To conduct printing on a receipt sheet and a slip sheet using a same printer by employing a spring plate filling the gap between main and sub- traveling path guides and touching the receipt sheet traveling face on the guide with a moderately weak pressing force thereby eliminating the need of a solenoid, operation control thereof, and the like.

Title: Drain separating mechanism for steam turbine
Inventor: ITO NOBORU
IPC: F01D9/02
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To prevent erosion of a diaphragm outer ring at a subsequent turbine stage when collected water drops are guided to a turbine exhaust hood by a method wherein a passage to discharge drains to the outside is formed in a spread opening spreading toward the outflow side of drains. SOLUTION: A drain catcher 19 in which a passage 21 is formed is formed in a diaphragm outer ring 15. The passage 21 is formed in the shape of a diffuser, the inlet side is formed into an opening 22 having a comparatively smaller cross section and into a spread opening 23 having a cross section gradually increased toward the outlet side. In the so formed diaphragm outer ring 15, a drain catcher 19 to capture water drains flied by the centrifugal force of a turbine moving blade or flowing along a wall surface 20. When water drops are discharged through the passage 21, a velocity of flow of water drops is decreased by the spread opening 23 and a pressure is restored.  Since water drops of which the velocity of flow is decreased are also decreased in a jet force following reduction of speed energy, when the water drops are collided with the diaphragm outer ring 24 at a subsequent turbine stage, an impact force is remarkably decreased.

Title: Method for filling leak oil sensing device with oil swelling substance
Inventor: NAKATSUKA YUJI
IPC: B01J4/00
Filed: 1990-08-31
Abstract: PURPOSE:To make filling of oil swell substance accurately by a specified volume by dissolving the substance in a solvent in a specified weight ratio, and injecting a certain amount of mixture liquid obtained into a case. CONSTITUTION:A case 1 is provided with an oil influx hole 2, followed by filling of a certain volume of oil swell substance 3 having uniform particle dia., wherein the dia. of the hole 2 is constructed smaller than the particle size to preclude the substance 3 from flowing out. An oil influx sensing means 4 is furnished on a lid 6, and when the substance 3 is swollen by the oil having flowed in from the hole 2, the means 4 receives the swell force from a transmissive member 5 and senses oil influx. When the case 1 is to be filled with the substance 1, a specified amount of substance 3 is measured and mixed with a solvent 7 of certain times as heavy as the substance 3, and if they are agitated thoroughly, particles of the substance 3 are dispersed evenly in the solvent 7, and also the particle dias. are made uniform. When this mixture liquid is poured into the case 1 by a certain amount, the solvent 7 volatilizes in a short time, and only the oil swell substance 3 remains in the case 1. Therefore, the oil swell substance 3 of specified volume accurately can be put fully in the case 1 by means of studying in advance the relationship between the weight and the volume.
