Title: Pressure sensor
Inventor: HAMAKAWA ETSUZOU
IPC: G01L9/06
Filed: 1983-07-08
Abstract: PURPOSE:To enable continuous detection of water level correcting the temperature by allowing the action of pressure subjected to a diaphragm on one of two electrode plates sandwitching a pressure-sensitive conductive rubber to convert the force into an electric resistance. CONSTITUTION:As water is supplied to a water receiving tank 3, a diaphragm 31 is deformed so much as to grasp a standard resistance section 34 of a conductive rubber 33 between electrode plates 37 and 42 and a reference resistance value corresponding to the predetermined reference pressure is detected. Subsequently, the electrode plate 42 is pushed up against the pressure of a spring 45 to grasp a measuring resistance section 35 of the rubber 33 between the electrode plates 37 and 40 and a measuring resistance value corresponding to the pressure is detected. Then, the pressure is determined by the ratio between the measuring resistance value and the standard resistance value thereby enabling continuous detection of water level with the correction of the temperature assuring a higher reliability of the detection.

IPC: C08G63/78
Filed: 1978-10-09
Abstract: PURPOSE: To provide the title equipment in which a shell-and -tubetype heat exchanger so designed that the vapor flow in the shell and the cooling water tubes become rectangular each other is installed, as a condenser, over the condensate tank to prevent the vacuum-line clogging.  
     CONSTITUTION: The present invention relates to a novel manufacturing equipment  for polyesters carrying, as a condenser, a shell-and-tube type heat exchanger so  designed that the vapor flow in the shell and the cooling water tubes become rectangular each other; the equipment works as follows: The reaction system held in the  polycondensation vessel is put to a state of reduced pressure, evolving a vapor comprising an alkylene glycol and bis(-β-hydroxyalkyl)terephthalate and the accompanying oligomer spray. Most of the spray, though attached to the pipe wall adjacent to the exit of the vessel, may flow down in a molten state into the vessel by  heating a jacket 8. Whereas, said vapor along with part of the spary is cooled by  the condenser 14 described above into droplets which fall in the condensate tank  10. The accompanying fine mist may also be converted into droplets at the same  time, becoming free from being subjected to suction through the vacuum-line 12 to  the ejector 13. The process described above enables the vacuum-line 12 to be prevented from clogging.

Title: Transmission controller

IPC: H04Q3/42
Filed: 1993-04-30
Abstract: PURPOSE:To improve a sneak path suppression performance by suppressing the sneak path which can not be suppressed by the selection of a balance circuit network by using an echo canceller. CONSTITUTION:Plural circuit networks BN are prepared, and they are successively connected with a two-wire/four-wire conversion part H. White noise is added from a transmitting end and power appearing at a receiving end (sneak path amount) is measured and compared. By selecting the balance circuit network which becomes minimum power at a point of time when the measurements of all the balance circuit networks are terminated, the selection of the balance circuit network is automated. By impressing the same white noise after an optimum balance circuit is selected and adjusting the tap coefficient of the adaptive filter of an echo canceller ECa provided in parallel with the two-wire/ four-wire conversion part H so as to cancel the sneak path components to the output on the side of four-wire, the sneak path which becomes the adjusting remainder by the setting of a balance circuit can be further suppressed.

Title: Magnetic recording medium
Inventor: SUZUKI REIKO
IPC: G11B5/735
Filed: 1993-04-30
Abstract: PURPOSE:To enhance the strength of a nonmagnetic substrate as a constituent of a magnetic recording medium by using a base film with a coating layer contg. inorg. particles having >=5 Mohs hardness, a binder and a lubricant on the principal face as the substrate and disposing a magnetic layer based on magnetic powder and a binder on the rear side of the base film. CONSTITUTION:The particle diameter of inorg. particles in a coating layer formed on a base film is regulated to 0.01-0.1mum and the content to 1-10 pts.wt. per 100 pts.wt. binder. The reason for the regulated particle diameter is that the service life of the knife of a slitter used for cutting a medium with the resulting substrate to the width of a product is shortened in the case of >0.1mum and cutting is difficult in the case of <0.01mum. The particles are made of SiO2, Al2O3, Cr2O3, ZrO2, TiO2, etc. In the case of <1 pt.wt. content, the substrate is liable to scraping and drop-out increases. In the case of >=10 pts.wt., the service life of the knife is shortened. Satisfactory characteristics are ensured by the above-mentioned regulation.

Title: Evaporating and thickening method for waste photographic processing liquid
Inventor: KUREMATSU MASAYUKI
IPC: G03D3/00
Filed: 1990-05-15
Abstract: PURPOSE:To lower the concn. of the odorous gases of a condensed distilling liquid and to reduce the size of the evaporating and thickening device by concentrically double disposing an evaporating and thickening column and a cooling and condensing column, communicating the two columns in the upper part and constituting the columns in such a manner that the pressures therein can be reduced. CONSTITUTION:A waste photographic processing liquid is injected into and stored in the evaporating and thickening column 1 which withstands a reduced pressure. The cooling and condensing column 1A is provided on the inner side nearly concentrically with the column 1. The two columns are kept connected with each other in the upper part and a pressure reducing means 7 is connected commonly to these columns to reduce the pressures therein. The waste photographic processing liquid is sent from a waste liquid storage tank 31 into the columns by a liquid feed means 3 consisting of a solenoid valve 6A. The waste liquid is subjected to the repetition of the heating and evaporating under the reduced pressure and the heating and evaporating in the process of spraying and dropping, by which the liquid is efficiently and rapidly thickened. The steam coming into a cooling means 8A through the communicating part is captured by this cooling means. The steam is cooled to condense and is recovered in the form of water drops. Such recovery is effective in lessening the exertion of large load in order to maintain the normal reduced pressure state by a pressure reducing device 7 when the reduced pressure balance in both columns is lost by the generated steam.
