Title: Manufacture of thin film magnetic head
Inventor: NAMIKATA RYOJI
IPC: G11B5/31
Filed: 1988-06-23
Abstract: PURPOSE:To surely select and delete only the undesired parts of an upper magnetic core by using an upper magnetic core formed in the form of a film as one of two electrodes and forming the other electrode at a position near the surface of the undesired part of said upper magnetic core to perform an electrical discharging process. CONSTITUTION:An upper magnetic core 3 is used as an electrode of the work side and an electrode 6 of the tool side is set near the core 3. Then an electrical discharging process is repeated to perform the transient arc discharging between both electrodes. Thus a part near the electrode 6 is deleted by a minute amount on the surface of the core 3. In such a way, the thick layer of the core 3 is deleted with the sequential advance of the electrode 6. When the layer of the core 3 is totally deleted down to an insulated layer 5, the electrode of the work side is also eliminated and therefore the electrical discharging process is automatically discontinued. Thus it is possible to surely delete only the layer of the core 3 with distinction secured from other layers.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of a flowmeter and a mass-flow-rate control apparatus which are used for a production process using a toxic and reactive process fluid. SOLUTION: A flow rate sensor 114 detects a flow rate, and a setting point is set on the basis of a preset temperature condition and a preset pressure conditions. A valve driving device 124 which is controlled by a control device 122 operates a flow control valve 126 so as to become a flow rate based on the detected flow rate and on the setting point. The control device 22 accesses a calibration data set, and it decides the quantity of a fluid to be supplied by the flow control valve 126 on the basis of the detected flow rate and the setting point. The data set is generated over the whole operating range of a flow-rate control apparatus 101 by using a calibration fluid whose characteristic is similar to that of a process fluid. The flow-rate control apparatus 101 is calibrated by using the calibration fluid, and the data set is generated in such a way that fluid data which is stored in a database is used and that calibration data is converted.

Title: Sink
Inventor: TAKEYAMA HIROSHI
IPC: A47B77/02
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To execute the heating cooking in a water tank mounted in a sink by comprising the sink mounted on an upper surface of a cabinet, the water tank mounted in the sink, and a heating means for heating the water tank. SOLUTION: An insulating part 5 is formed outside of an inner wall 6 of a water tank 3 mounted in a sink 2, and an induction heating coil 4 as a heating means is mounted on a rear surface of the insulating part 5. The water is directly supplied from a cock of waterworks to the water tank 3 of which a drain port 8 is closed by a lid. Then the power is supplied to the induction heating coil 4, and the wall 6 in the water tank made of ferrite stainless increases its electric resistance by the magnetic force and generates the heat, whereby the water in the water tank 3 is heated to boil vegetables and the like. After the boiling, the water is slopped over only by removing the lid of the drain port 8 of the water tank 3 for draining.  During this boiling cooking work, a cooker hardly moves, and the overturning of a heavy pot becomes unnecessary, so that the boiling cooking work can be efficiently executed while reducing the physical load. The water tank can be also used as a bowl for cooling besides the heating cooking.
