Patent JP-H08105092-A (JP)
Title: Flush valve
Inventor: SAITO SHIRO
IPC: F16K21/04
Filed: 1994-10-05
Abstract: PURPOSE: To prevent any residual water from being frozen in making any drain so as not to be left behind in an internal space whenever the drain is automatically stopped by interconnecting a base end to this internal space lying between a seat part and a drain port, and installing a cylinder provided with an intake valve, in an upper end to be situated higher than the seat part. CONSTITUTION: When a solenoid valve 7 is operated, a valve element 5a separates from a seat part 6. Therefore a large quantity of water flows out toward a drain port 10 from a feed water port 2, whereby it is fed, under pressure, even into a waterway 15 of a cylinder 12, pressing another valve element 24 to the inside of a sliding hole 22 toward a lower part of this valve element 24 through a small tube part 21. Accordingly, an O-ring 27 of this valve element 24 closes an upper end of the sliding hole 22, so water lifted up in the small tube part 21 from the waterway 15 will not be leaked to the outside from the cylinder 12. Subsequently, the water is filled up fully in a pressure chamber 9 from a small hole 5c and again the valve element 5a comes into contact with the seat part 6.  Then draining is stopped and the drain goes down with its own weight and thereby the small tube part 21 comes to negative pressure, so it flows into the waterway 15. In consequence, an internal space 11 will not turn to the negative pressure. With this constitution, a freeze of residual water in the cold season is thus preventable.

Filed: 1985-11-28
Abstract: PURPOSE:To reduce the size and cost of a data projector/display device, by using the device as an overhead projector (OHP) as well as a slide projector (SP) by switching a shutter. CONSTITUTION:When this device is used as an OHP, the liquid crystal shutter 15 of the 1st optical path 6 is opened and the liquid crystal shutter 27 of the 2nd optical path 7 is closed. Then the light of a light source 1 passes through the optical path 6 and is projected from the mirror 4 of a projecting means 2 through an OHP sheet 16. The projected light forms an image on a screen. When this device is used as a SP, the shutter 15 of the 1st optical path 6 is closed and the shutter 27 of the 2nd optical path 7 is opened. Then the light passes through the optical path 7 and is reflected by mirrors 28 and 29 after passing through a film for SP 23. The reflecting light is further reflected by a half mirror 17 and reaches the projecting means 2. The light is then projected from the mirror 4 to the screen and forms an image. Since the magnifications of both projected images are made equal to each other, images can be projected and displayed in almost the same magnitude even when they are projected through either one of the optical paths.

Abstract: PURPOSE:To facilitate the crossing of an automatic cleaning apparatus over an automatic doffing apparatus, etc., in the course of traversing along the spindles of the same spinning frame, by providing the cleaning apparatus with an air duct and making a part of the duct to be rotatable. CONSTITUTION:The automatic traversing and cleaning apparatus 1 is furnished with an air duct 8 dangling along the side face of a spinning frame and is traversed along the spindles of the spinning frame by the rail 3 above the spinning frame. In the above cleaning apparatus, a rotary part 15 of the air duct 8 is furnished at a position higher than the top of an automatic apparatus 11 for doffing and ending, etc., and moving along the spindles of the same spinning frame. When the automatic traversing and cleaning apparatus 1 is to be crossed over the automatic apparatus 11, the air guide 8b below the rotary part 15 is rotated and retreated to enable the free passage of the automatic apparatus 11. The air duct 8b is returned to the original position after crossing the automatic apparatus 11 by a rotating means 18 such as coil spring attached near the rotary part 15 and cleaning is continued. Since no place is left uncleaned by the cleaning operation, the lowering of yarn quality caused by deposited fly waste can be prevented.

IPC: B41M5/42
Filed: 1985-11-29
Abstract: PURPOSE:To form the picture of a high density in a comparatively small amount of energy, by a method wherein a thermal ink-transfer color material layer is printed or applied on a base material sheet via a dye translation preventive layer. CONSTITUTION:A thermal ink-transfer sheet is piled on the upside surface of the image-receiving paper 8 consisting of a paper base material 6 and the dyeable resin layer 7 formed on its upside surface and then, the upside surface of the heat-sensitive ink-transfer sheet is pressed and heated with a thermal head 9. Though the dye 3a in a thermal ink-transfer color material layer 3 is sublimated at that time, the sublimated dye 3a can not be translated upwards because of the presence of a dye translation preventive layer 2 and most thereof is translated toward the dyeable resin layer 7 of the image-receiving paper 8 to dye this dyeable resin layer 7. Therefore, a high ink-transfer efficiency is obtained and the picture image of a high density can be obtained.
