Title: Thin film magnetic head
Inventor: EGAWA MASAHIRO
IPC: G11B5/31
Filed: 1995-01-20
Abstract: PURPOSE: To obtain a thin film magnetic head which realizes the high precision of the width of a core which is a part of a yoke regardless of the number of steps of coil layers. CONSTITUTION: A lower insulating layer 22 and a lower magnetic pole layer 25 are formed on the upper surface of a substrate 21. The end part of the lower magnetic pole layer is made to overlap the end part of the lower insulating layer. The overlapping part is used as the connection part between the lower magnetic pole layer and an upper magnetic pole layer 31. By elevating the lower magnetic pole layer as above described, the bottom of a hole part 30 of which the connection part between the lower magnetic pole layer and the upper magnetic pole layer is composed becomes shallow. Therefore, the thickness of resist which fills the hole part when the upper magnetic pole layer is formed can be small and, even if the exposure rate is small, the resist in the hole part can be removed and the overexposure can be avoided.  With this constitution, the upper magnetic pole layer can be patterned with a high precision and, even if the core width is small, the head can be manufactured with a high precision.

Title: Gas purge equipment
Inventor: ITO TAKESHI
IPC: H01L21/285
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To prevent the attachment of particles and increase a gas purge processing efficiency by making the flow of gas for purging and clean air smooth in a gas purge box. SOLUTION: After setting cassettes in cassette racks 15, a door 12 is closed and then gas is supplied into a space through a gas supply port 21 and the gas is exhausted through an exhaust port 23 at the same time. A motor fan 18 of a clean unit 17 is turned OFF. By this method, gas for purging is not stagnent in a gas purge box 11 and wafers in the cassette are gas-purged and no particle attaches to the wafers. When an air intake 19 is opened to take air in, the door 12 is opened to open front faces of the cassette racks 15 and the motor fan 18 is turned ON. As a result of this, clean air is smoothly exhausted outside from the space 16 through the cassette racks 15. Therefore, the wafers can be cleaned efficiently.

IPC: G07D7/04
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To realize the design method of a discrimination reference capable of performing development in the short period of time. SOLUTION: A block probability addition part 14A selects a block for adding a block probability (step S143). In this case, the blocks of the same section constitution for which a block false probability VB, a block true probability PB and a block point W are the same are selected so as to obtain only one of them. Then, for the selected block, the block false probability VB, the block true probability PB and the block point W are obtained (steps S344-S146.) When the block satisfies true category conditions, the false probability VB of the block is added to an erroneous discrimination rate V (step S148). In this case, the coefficient G of multinomial drstribution is multiplied to the block false probability VB to be added. Such processings are performed to the block true probability PB as well and further, the processings are performed to all the blocks.

Filed: 1986-02-07
Abstract: PURPOSE:To avoid degradation of yield and degradation of quality anticipated in making the pattern of a semiconductor device finer by a method wherein both optical polymerization by a far-ultraviolet ray and thermal polymerization by heat of a stage are applied to a photoresist film pattern. CONSTITUTION:A semiconductor substrate 4 is transferred onto a stage 3 and heat is applied to the semiconductor substrate 4 from the stage 3 to carry out thermal polymerization of the photoresist on the substrate 4. On the other hand, a far-ultraviolet ray is applied to the substrate 4 from a light source 5 directly above the stage 3 and optical polymerization of the photoresist on the substrate 4 is carried out to strengthen the photoreist. In other words, the optical polymerization of the photoresist pattern on the surface of the substrate 4 placed on the stage 3 is promoted by the far-ultraviolet ray with the wavelength range of 200-300nm applied to the whole surface by the light source 5 and, at the same time, its thermal polymerization is also promoted by the heat of the stage 3 with a built-in heater. With this constitution, etching-resistant properties can be improved.

IPC: G11B17/26
Filed: 1994-01-31
Abstract: PURPOSE:To simplify the structure of a recording medium transferring device by keeping an engagement or release state of holding for a positioning pin against a recording medium which interlocks a transfer action when it engages one of paired engagement grooves formed along a transfer path. CONSTITUTION:A transfer shift block 73 has a positioning pin 110 which selectively engages a positioning engagement groove 77 or 78. When the pin 110 is engaging the groove 77, an engagement lever 100 is set at a position where a disk cartridge 320 is held and therefore transferred between a storing magazine and a disk drive part. Meanwhile the pin 110 gets out of both grooves 77 and 78 when the block 73 is positioned at the side of the storing magazine. Thus a plunger 94 is actuated to move the pin 110 to a position where the pin 110 engages the groove 78. Therefore the lever 100 releases the cartridge 320 and remains in the storing magazine.
