Title: Magnetic recording method
Inventor: SUZUKI JIRO
IPC: G11B5/00
Filed: 1985-05-09
Abstract: PURPOSE:To prevent the malfunctions of a detector which is caused when a forger embeds a punch part with a different material, by using a magnetic card containing a magnetic film at the area equivalent to a punched part. CONSTITUTION:The designated DC current is first applied to the 1st magnetic head 21 which is under a going process 25 of a detection mechanism to produce a magnetic field for the head 21. Thus a forgery preventing magnetic film 31 and a forged magnetic film are evenly magnetized. Here the film 31 and a forging magnetic film 32 deliver outputs P1 and P2 respectively. Then a magnetic field is applied to the 2nd magnetic head 22 in the direction opposite to the head 21 so as to eliminate the output P2 of the film 32. Thus the output is partly degaussed. In this case, the output distribution of the film 31 is equal to an output P3 after degaussing. In other words, the degaussed output is equal to (P1-P3). Then the 3rd magnetic head 23 reads a magnetization pattern to detect the accurate punching and the using frequency of a magnetic card is known. That is, a forged part 32 is invalidated at this time point. Thus it is possible to prevent a case where a magnetic card is used wrong by a forger.

Title: Device for preventing cooling of bath water
Inventor: IRIE TAKESHI
IPC: F24H1/00
Filed: 1984-05-15
Abstract: PURPOSE:To make it possible to prevent cooling of a bath water when the operation of the bath is in standstill by providing a shape memory alloy in a driving body for a sluice valve connecting the bathtub to a bath furnace. CONSTITUTION:A spring 13 is formed spirally so that a shape memory alloy is used therefor which senses a high temperature of hot water when the bath furnace is in operation and contracts, and which expands at the time when the bath is in standstill, that is, at the time of a low temperature. When the operation of the bath furnace is stopped, the spring 13 which has so far been heated at the high temperature is cooled and extends to the original condition, so that the sluice valve 3 is closed against a pushing force exerted by a spring 12, and water sealing faces 9 and 11 come into contact with each other to suppress the convection of the bathtub. In a case where the temperature of atmospheric air is lower than the temperature of hot water, the bath furnace in turn acts as a cooler for cooling hot water in the bathtub. However, the convection between the bathtub and the bath furnace is prevented by means of the sluice valve 3.

Title: Automatic pumping plant
Inventor: NISHIMURA SHIYUNICHI
IPC: F04B23/02
Filed: 1980-07-18
Abstract: PURPOSE: To protect the thin film pressured receiving body in a pressure tank from foreign matters and provide stabilized operation of an automatic pumping plant, by supporting with freedom of horizontal drill a cylindrical filter provided with pores for filtering the foreign matters/perforated in the horizontal direction on its external surface, on the way of a connection passage through which the exhaust passage of a pump head is connected to the pressure tank and/by which water flow is reciprocated.  
     CONSTITUTION: The pumped-up water 18 which is discharged from a pump head section 3 collides with a cylindrical filter 12 into which a number of pores are perforated. Since minute gaps 15 and 16 are provided around the cylindrical filter 12, the filter can drift in the horizontal direction. Even when the cylindrical filter 12 vibrates slightly by water flow and foreign matters adhere to a pore 17, the foreign matters fall down. Besides, since the water which passes through the cylindrical filter 12 and enters a pressure tank 5 flows into a pressure chamber 4 through the/same cylindrical filter 12 in the reverse direction, the foreign matters which adhere to the external surface of the cylindrical filter 12 can be removed positively by the multiplication between the pressure of water which returns to the pressure chamber 4 from the pressure tank 5 and the minute vibration of the cylindrical filter 12. This protects the thin film pressure receiving body in the pressure tank from the foreign matters, such as sand, etc. and can provide a stabilized automatic operation of a pumping plant.

Title: Production of ceramic sintered compact
Inventor: TANAKA SHIGERU
IPC: H01C7/10
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To obtain a grain boundary-utilized type ceramic stabilized in grain boundary level at low cost by immersing a ceramic stock in an organic binder followed by heat treatment at low temperatures, incorporating powder serving as an ingredient in the system under agitation and then conducting a sintering. SOLUTION: First, ceramic stock powder (e.g. ZnO powder) is immersed in an organic binder (e.g. an aqueous solution of polyvinyl alcohol), then taken out and heat-treated at <=150 deg.C. Subsequently, the heat-treated stock powder is incorporated with powder serving as an ingredient (e.g. Bi2 O3 powder) followed by mixing and agitation in high speed in e.g. a jet mill to effect uniform adherence of the ingredient powder to the surface of the stock powder. Next, the resultant stock powder is sintered to effect segregation of the ingredient onto the grain boundary of the resultant sintered compact, thus obtaining the objective sintered compact. Thereby, since the stock powder is immersed in the tacky organic binder and then heat-treated at low temperatures, the electrostatic force on the grain surface is changed, preventing the grain itself from agglomeration.
