Title: Production of magnetic head
Inventor: NAKAO SATORU
IPC: G11B5/31
Filed: 1987-02-05
Abstract: PURPOSE:To improve the permeability and the recording and reproducing characteristic in a high frequency area by adopting the structure where uniaxial anisotropy is induced by a needlelike or layered structure grown in a thin film by the oblique incidence effect at the time of forming the magnetic thin film. CONSTITUTION:When a magnetic film 1 is formed as the thin film on a magnetic core board 6, a direction of material incidence is set with respect to a perpendicular drawn on the board 6, and uniaxial anisotropy is induced in the film surface in a direction of an arrow 75 orthogonal to the direction of projection on the film surface of the incidence direction by oblique incidence. Cores are cut out from a board 82, on which the film is formed, so that the direction of the arrow 75 of the axis of easy magnetization is orthogonal to the direction of the magnetic path, and these cores are laminated and adhered one by one to obtain core half body blocks 92, and surfaces to face each other of cores are polished and smoothed, and winding windows 4 are provided in one core half block 92. Both core half body blocks are allowed to face each other with a gap material between them and are adhered with a glass, and this assembled core block is cut in a prescribed position to obtain one core. Thus, the permeability in the high frequency area of the magnetic film is improved and the recording and reproducing characteristic is made wide-band.

IPC: G04B19/20
Filed: 1989-01-31
Abstract: PURPOSE: To easily and quickly read the time at any time by turning a disc for sequentially indicating numerals indicative of the hour stepwise every hour and viewing the numeral through an opening made in a dial. CONSTITUTION: A gear 10 integrated with a cylindrical shaft 9 turns once clockwise every hour and a meshed gear 11 turns a quarter of revolution counter clockwise every hour. The rear 11 fixed the outer end 19 of a coil spring 18 and the inner end is fixed to a gear 17 which meshes the toothed edge 16 of an indication disc 6 and can not turn counter clockwise. When the hour elapses, the spring 18 is wound continuously while storing the energy. As the time elapses, a sectoral gear part 27 turns a pinion 28 and moves an anchor 33. Subsequently, the arm 40 of a resilient plate 41 is disengaged from the tab 42 of disc 6. The gear 17, and thereby the edge 16, is turned by the energy discharged from the spring 18 until a next tab 42 is engaged with other arm 40. Consequently, the disc 6 is turned by 30 deg. accurately and instantaneously.

IPC: H01L21/027
Filed: 1994-01-26
Abstract: PURPOSE:To enhance uniformity in the tune width of resist by connecting a developer in-line with a resist line width measuring unit through a controller and performing the feedback control of the ambient temperature and the like of a developer based on the measurement data of the line width of resist. CONSTITUTION:The pattern forming unit 10 comprises a resist coater 12, a prebake unit 14, an exposing unit 16, a developer 18, a post-bake unit 20 and a resist line width measuring unit 22 connected in-line.

It may seen that a problem is present within the post-bake unit 20 or during development, but no problem is actually present because an abrupt fluctuation seldom takes place.
Patent JP-H11224131-A (JP)
Title: Voltage regulator
Inventor: SUDO MINORU
IPC: G05F1/565
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To suppress small the source current when a voltage regulator(V/R) is actuated. SOLUTION: When the V/R is actuated, a clamp circuit 120 is added to the output of an error amplifier 13. At the same time, a capacitor 122 begins to be charged with the current of a constant-current circuit 121 and a switch 123 is held ON until it is charged to a certain constant voltage. When the V/R is actuated, the output voltage Verr of the error amplifier 13 is clamped to source voltage VDD-Zener voltage Vz in a certain constant period, so the current ON resistance of an output transistor 14 has a certain ON resistance value since a gate-source voltage is applied by only Vz. Then the ON resistance value of the output transistor at the time of the actuation is not made too small, and consequently the source current of the V/R at the time of the actuation can be suppressed small.

Title: Multi-partitioned container with preventive function against breakage
Inventor: UEMATSU YASUSHI
IPC: B65D81/32
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a container, by providing a easily breakable part from which a gas leaks to the outside of the container at a part of the container composed of a plurality of partitioned chambers and providing another breakable part to connect the partitioned chambers at a part or the whole of partitions between partitioned chambers. SOLUTION: A sheet fragment 3 having a different quality from a container body is held in the center of a partition 2 and welded therewith. This part can be easily broken by a force as large as a human strength and the partitioned chambers A, B are connected to each other. In this condition, when the whole body of the container is made soft by rubbing it, the chemicals in the chambers A, B are mixed together in the enclosed container. The sheet fragment 3 is selected from such materials that the width is larger than the width of the partition 2 and the sealing strength becomes weaker than the welded part (partition part 2) of the container body. Accordingly, a gas originates when the container made soft by rubbing is left for a long time and when the inside pressure has risen, the gas leaks out from the sheet fragment 4 made of the same material with the sheet fragment 3.

Title: Method and mud gun for closing tapping hole of furnace
Inventor: UERUNAA SHIYUNAIDAA
IPC: F27D3/15
Filed: 1989-02-03
Abstract: PURPOSE: To dispense with correct selection at the point of the time to insert a tapping rod and consequently to enable the prevention of the unexpected flooding of a melt by pushing the tapping rod together with mud into a tapping guide groove.  
     CONSTITUTION: When a mud gun 5 is operated, a pushing piston 6 extrudes the mud 8 in a feed direction 7 and, at this time, the mud 8 carries the tapping rod 10 simultaneously until the front end of the mud projects into the inside chamber 15 of a blast furnace 2. When the tapping guide groove 3 is packed with the mud 8 and simultaneously the tapping rod 10 advances, the edge of a disk 14 enters the tapping guide groove 3 and thereafter, the edge of the disk curves to the direction opposite to the feed direction 7, thereby coming into tight contact with the wall of the tapping guide groove 3. When the front end of the tapping rod 10 projects into the inside chamber 15 of the blast furnace 2, a pawl body 16 supported swivelably by the mouthpiece 4 of the mud gun 5 detains with a peripheral engaging groove 17 at the rear end of the tapping rod 10, thereby prohibiting the carry over any more. After the mud 8 in the tapping guide groove 3 cures, only the pawl body 16 is lifted and the mud gun 5 is swiveled to be detached. The tapping rod 10 remains in the tapping guide groove 3 closed by the mud 8 before the next tapping.
