IPC: C02F5/08
Filed: 1990-01-30
Abstract: PURPOSE:To prevent the formation of black stains on a toilet bowl surface and the deposition of scale in a toilet bowl trap and to deodorize generated ammonia by allowing a solution of a molded material containing a specified solid acid and a subliming substance to flow down along the surface of a toilet bowl and into a trap thereof. CONSTITUTION:A molding material consisting of at least one solid acid selected from among adipic, succinic, fumaric, and orthophthalic acids and a molding base material containing a subliming substance is dissolved in a dissolving unit provided midway on a pipeline for toilet flushing water, and the solution is allowed to flow down along the surface of a toilet bowl and into a trap thereof. The amount of the solid acid in the molding material will vary depending upon the weight of the molding material, the size of the dissolving unit, and frequency of use of a toilet bowl, ranging from 30 to 70wt.%. The base material is employed for the purpose of dissolving the solid acid at an appropriate speed without causing disintegration on use and improving the moldability of the solid acid. As the subliming substance in the base material, p-dichlorobenzene is preferably used.

Abstract: PURPOSE:To prevent the deformation of the wall part of a drain dust, by communicating the drain duct with a space having dry steam present therein through  a balance duct to prevent the rise of pressure in the drain duct when an accident happens. CONSTITUTION:Wet steam is flowed in from a steam inlet 2 during a stationary state to be flowed into a separator 7 through the perforated plate 4 in a distribution chamber 3 and moisture in wet steam is collected while dry steam is flowed into a space 16 and drain is flowed into a drain duct 12 from a flowing 8 to be stored in a drain tank 13. When an accident such as the trip of a steam turbine happens, pressure in a moisture separating apparatus is abruptly lowered and drain in the drain tank 13 is evaporated but, because the space 16 and the drain duct 12 are communicated through a balance duct 15, the generated steam is flowed into the space 16 through the balance duct 15 and an opening 22 and is not flowed into the separator 7.

IPC: B08B9/027
Filed: 1987-01-30
Abstract: PURPOSE:To easily perform ultrasonic flaw inspection from an in-tube surface by removing scales in a tube to be inspected such as a heat conduction tube and maintaining a state suitable to the flaw detection. CONSTITUTION:When the amount of scales deposited in the heat conduction tube 4, specially, a bend is small, water for cleaning is sent in a hose 8 under pressure from a supply water tank 15 through a strainer 17A, a cartridge type filter 17B, a counter-clockwise rotary valve 8b, and a pressure switch 17C and injected into a tube 1. In this operation, the scales deposited in the heat conduction tube 4 are pressed by a flow of water flowing in the heat conduction tube 4 from the tube 1 to rise and easily pass in the tube without clogging. When the amount of scales deposited in the heat conduction tube 4 is large, on the other hand, gaseous N2 is supplied into the hose 8 from a gaseous N2 supply pipe 14 in addition to the water from the tank 15 and the water which contains the gaseous N2 is injected into the heat conduction tube 4. Thus, the ultrasonic flaw inspection from the in-tube surface is carried out.

Title: Optical isolator
Inventor: TAKAHASHI KAORU
IPC: G02F1/09
Filed: 1985-02-05
Abstract: PURPOSE:To make the optical isolator in small scale and a light weight and to improve a productivity and a performance of the titled isolator by preparing on a substrate, a magnetic garnet film having a great deal of substituents of Bi without a large difference of a grid constant. CONSTITUTION:A linearly polarized light radiated from a semiconductor laser 1 of the optical isolator is condensed with a lens 2. The polarized light rotates at angle of 45 deg. by passing (BiLu)3Fe5O12 and then passes a Gd3Ga5O12 substrate 4 substituted with Ca-Mg-Zr and further reaches to an optical fiber 3 through a polarizer 7 which is parallel to the direction of the polarized light and is capable of passing said light. The linearly polarized light which is the returned light coming from an optical fiber 3 and passes though the polarizer 7, passes through the substrate 4. When said straight polarized light passes said magnetic garnet of (BiLu)3Fe5O12, said light rotates at the direction of polarization of 45 due to a non reciprocity depending on Faraday effect whereby the radiated light coming from the laser intersects at right angle with the polized light of the returned light. The performance and the productivity of the titled isolator is improved by applying the magnetic garnet having the composition of BixLu3-xFe5O12(1.0<=x<=3.0) which epitaxially grows on the Gd3Ga5O12 substrate.

Title: Muting circuit of video tape recorder

IPC: H04N5/91
Filed: 1983-02-08
Abstract: PURPOSE:To attain the proper muting of a sound reproduction signal by discriminating whether a tape is driven normally or not by the fact whether a control signal is detected in the prescribed timing or not. CONSTITUTION:The 1st discriminating circuit 15 discriminates whether the even order pulses (the 2nd, 4th...) are within a prescribed time range or not on the basis of the odd order pulses (the 1st, 3rd...) of the output of a delay circuit 3. While the 2nd discriminating circuit 21 discriminates whether the odd order pulses are within a prescribed time range or not on the basis of the even order pulses. The semistable periods of MM13 and 20 of the final stage of the discriminating circuit are set so that they overlap with each other while they are triggered. Therefore the output of an NOR gate 14 is always kept at a low level as long as the cycle of the reproduction control signal is within a prescribed range. Thus the proper muting is possible by discriminating whether the control signal is detected in the prescribed timing or not.

Abstract: PURPOSE:To obtain formed products with uniform properties by means of removing unevenness for filling raw material into a mold by preserving a constant gap freely adjustable between the contact sunfaces of both metal molds, when the tip of each piston rod of a cylinder touches the contact surface of said mold. CONSTITUTION:The operation of a cylinder 35 and the movement of a movable disk 6 are stopped and the gap between contact surfaces 2', 7' of metal molds 2, 7 is caused to maintain a constant distance required to fill raw material beads in said gap. At this condition, the raw material beads are filled by a raw material supplying device 34. Further, the pressurized fluid supplied from a port 16 is stopped by changing a switch valve 19 and the pressure for a piston rod 10 is released, and in this state, the movable disk 6 is caused to advance to the side of stationary disk 1 by actuating the cylinder 35 again, and then the rod 10 is caused to go back owing to be pushed by the piston rod 9 and to be in contact with the contact surfaces 2', 7'. Next, the molds are tied and pressurized, and the raw material beads are foamed, and thus, the objective foamed synthetic resin-product is completed by supplying steam into the metal molds 2, 7.
