Title: Video tape recorder
Inventor: IZAWA FUMIO
IPC: G11B5/00
Filed: 1983-02-09
Abstract: PURPOSE:To erase completely the preceding recording content of a video signal at postrecording of the video signal by providing an erase head for video signal having a magnetic gap only at a position corresponding to the 1st region where the video signal on helical tracks is to be recorded. CONSTITUTION:The head 15 for erasing video signal has a magnetic gap 15a formed over a length A only at a position corresponding to the 1st region 3 of a helical track 2 and a head 16 for erasing audio signal has a magnetic gap 16a formed over a length B only at a position corresponding to the 2nd region of the helical track 2. Further, these erase heads 15, 16 are incorporated in one body to constitute one combination head. On the other hand, recording/reproducing heads 22, 23 for control signal have respectively a magnetic gap only at a position corresponding to linear tracks 5, 6. Thus, the video signal and the audio signal on the helical tracks are erased individually.

Title: Method and apparatus for separating liquid
Inventor: TAMURA TAKASHI
IPC: B01D17/02
Filed: 1981-02-14
Abstract: PURPOSE: To separate a mixed liquid of an aqueos liquid and a non-hydrophilic liquid efficiently and inexpensively in high preciseness with a simple operation by filtering the same while the contact between a water containing sponge and the non-hydrophilic liquid is interrupted.  
     CONSTITUTION: After an external water tank 14 is filled with water, a filter cylinder 1 is entered into said tank 1 and, when a mixed liquid of oil/water is pouring into the upper cylinder 12 thereof, water is permeated through a cellulose sponge 7 corresponding to gravity of the thrown mixed liquid and flowed out into the water tank 1 through a discharge port 12 and excessive water is subsequently overflowed from an outflow port 15 as the water level in the water tank 14 is raised. On the other hand, an oil component is under a state always floated on the water layer above the cellulose sponge 7 and, when accumulated to a level exceeding an oil component take-out port 13, it overflows from said take-out port 13 to be flowed out. Separation efficiency can be mainly controlled by a flow amount of water from the outflow port 15.

Abstract: PURPOSE:To shorten a gaseous phase treating time for bringing excellent humidity sensitive characteristics and to obtain stable characteristics, by subjecting a temp. detecting element to gas phase treatment under pressure equal to or higher than the atmospheric pressure in a high temp. and high humidity atmosphere. CONSTITUTION:Voltage of 25V is applied onto a tantalum wire 1, for example, at 85 deg.C by using a 1mol/l aqueous phosphate solution to perform chemical forming treatment whereupon an anodic oxidation film 2 is formed. In the next step, a manganese dioxide layer 3 is formed on the anodic oxidation film 2 by the coating and pyrolysis of an aqueous nitrate solution with specific gravity of 1.3. In addition, a carbon layer 4 is formed on the manganese dioxide layer 3 by the impregnation and drying of colloidal carbon and a silver paint layer 4 is formed on said layer 4. Subsequently, water is put in a hermetically closed container and heated from the outside to fill the interior thereof with high temp. steam and the formed substance is subjected to gaseous phase treatment by using a pressure pot capable of raising internal pressure to increase the area of a tantalum oxide part not covered with the manganese dioxide layer. By this method, uniform heating and pressurization can be applied to the whole of an element.

Title: Liquid feeding device
Inventor: SASAKI TAKASHI
IPC: E03D1/30
Filed: 1983-02-10
Abstract: PURPOSE:To make it possible to discharge a liquid stored in a main storage tank while a fresh supply of the liquid into the tank is interrupted and to make the liquid supplied into, and discharged from, the tank through a single valve operation by a method wherein a changeover valve which closes when the liquid is discharged is provided at an inlet port formed in the bottom of an auxiliary storage tank provided in the upper part of the main tank. CONSTITUTION:A liquid discharge valve 16 closes when the main storage tank 5 and the auxiliary storage tank 6 are filled with the liquid. In that condition, the changeover valve 8 is urged upward due to the resilient force of a spring or the buoyant force resulting from the structure of the valve attached with a probe and a valve opening and closing jig 15 is lifted upward by a suspending jig 14. When the liquid discharge valve 16 is opened, the liquid 18 flows into a chamber 13 and the valve opening and closing jig 15 lowers due to the pressure of the liquid so that the valve 16 is closed. As a result, only the liquid 18 in the main storage tank 5 is discharged. Further, when the liquid discharge valve 16 is closed, the changeover valve 8 opens upward and a fresh liquid 19 flows into the main storage tank 5 from an inlet port 7 so that a ball tap 17 is opened simultaneously to thereby allow the liquid 19 to flow into the auxiliary tank 6.
