Title: Thin film magnetic head with tip submagnetic pole and its production
Inventor: NISHIDA SHUJI
IPC: G11B5/31
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To substantially eliminate harmful subpeaks by retreating the floating surface-side end part of an upper magnetic pole from the floating surface-side end part of a tip submagnetic pole in viewing from a floating surface. SOLUTION: The core width of this head is regulated to be substatially narrow by tip submagnetic poles 21, 22 respectively provided on a lower magnetic pole 8 and an upper magnetic pole 16. A recording magnetic field is generated with the gap layer between the tip submagnetic poles 21, 22. When a dimension with which the floating surface-side end part of an upper magnetic pole 16 is retreated from the floating surface-side end part of a tip submagnetic pole 22 is defined as the retreated height SH of the upper magnetic pole, the SH is made to be >=0.1 μm by controlling the retreated height SH of the upper magnetic pole.  Moreover, when the thickness of the floating surface-side end part of the tip submagnetic pole 22 is defined as the length SL of the tip submagnetic pole, a ration SL/SH is made to be >=1.0 by controlling the ratio SL/SH of the length SL of the tip submagnetic pole to the retreated height SH of the upper magnetic pole. Both of an overwrite characteristic and an offtrack profile or either of them are improved by controlling the retreated height SH of the upper magnetic pole and the ratio SL/SH.

Title: Composite cylinder
Inventor: OKITSU TOSHIO
IPC: B29C45/62
Filed: 1987-10-21
Abstract: PURPOSE:To load a compressive stress on the sintered alloy layer of an inner surface to improve resistances to abrasion and cracking, by a method wherein recesses and projections are formed on jointing boundaries between a cylindrical body and the sintered alloy layer to joint them while the amounts of shrinkage of the cylindrical body and the sintered allow layer from 800 deg.C to a normal temperature are specified. CONSTITUTION:The material of a metallic cylindrical body 1 is selected so as to have a linear expansion coefficient larger than the same of a sintered alloy 2 while recesses and projections 3 are formed on the jointing boundary between both of the cylindrical body and a sintered alloy layer to joint and integrate them, therefore, a compressive stress is applied on the sintered alloy layer. Both ends of the alloy layer 2 are embedded into the cylindrical body 1 in a condition that they are enveloped by the cylindrical body, therefore, the compressive stress of the alloy layer 2 is enhanced. The temperature of the starting point of shrinkage is 800 deg.C. Under a temperature exceeding 800 deg.C, both of the metallic cylindrical body and the sintered alloy layer are soft and cause plastic deformation easily, therefore, remaining stress will never be generated between both of them. The amount of shrinkage of the sintered alloy layer deltaA is made smaller than the amount of shrinkage deltaB of the metallic cylindrical body in order to provide the sintered alloy layer with a compressive stress.

Title: In-line electro hydraulic servo valve
Inventor: NEMOTO MASAMI
IPC: F15B13/044
Filed: 1988-10-24
Abstract: PURPOSE:To obtain the control proportional to the control current by providing a hydraulic balance part, in which the size of an airspace between a pocket and a tank port varies in accordance with a shift of a spool, so that the spool moves, maintaining a balance between a pressure difference in the right and left pockets and the driving force of a force motor. CONSTITUTION:When a control current is sent to the right and left force motors 4-1 and 4-2 an in-line electro hydraulic servo valve, a spool 1 moves to the right or to the left, owing to the driving force of the motors 4-1 and 4-2. As a result, the pressure in pockets 7-1 and 7-2 varies, making a pressure difference, and the spool 1 stops at a place where the said pressure difference and the driving force of the force motors 4-1 and 4-2 are balanced. In addition, the faster the spool 1 moves, the greater the flow rate of the pressure oil pushed out becomes, resulting in greater resiliency. Therefore, the movement of the spool 1 is attenuated. Thus, stable and high-speed responsiveness can be secured.
