Title: Production of magnetic head
Inventor: YAMAGUCHI KEIJI
IPC: G11B5/127
Filed: 1988-09-12
Abstract: PURPOSE:To prevent lowering of the force to joint a core and slider by cutting a magnetic block to a prescribed track width, then heat-treating the block at the temp. higher than the softening point of the glass for joining and lower than the softening point of a magnetic gap packing material. CONSTITUTION:The magnetic head under production is heated in a nitrogen atmosphere in the range from 515 deg.C softening point of low-melting lead glass to 820 deg.C softening point of borosilicate glass. Although 550 deg.C is above the softening point of the joining glass and associates the possibility of the removal of the core 1 from the slider 2, a solid phase diffusion arises between the borosilicate glass 3 to serve as the softening point at the time of joining the slider 2 and the core 1 and the ferrite to be the material of the core 1 and the slider 2, thus allowing joining of the core 1 and the slider 2 to some extent. The core is, therefore, no longer removed from the slider even if the magnetic head is heated to the temp. above the softening point of the joining glass. The joining glass softened by this heat treatment is repaired of the flaws made therein by cutting, etc., in this way and the degradation of the force to join the core and the slider is prevented.

Title: Ceramic laminated capacitor device
Inventor: YOKOYA YOICHIRO
IPC: H01G4/30
Filed: 1988-09-12
Abstract: PURPOSE:To prevent a generation of a low-melting point low-permitivity secondary phase on the interface of a dielectric layer and an internal electrode layer by including an oxide component, which increases a melting point of a liquid phase generated at high temperatures by reacting to a component in which TiO2 exceeds BaTiO3, in the internal electrode layer. CONSTITUTION:Why there is a generation of a secondary phase on the interface of a dielectric layer and an internal electrode layer is because a component, in which TiO2 exceeds BaTiO3, becomes a liquid phase in a firing process and it is solidified from the interface of the dielectric layer, which is cooled rapidly in a cooling process, and a vapor phase or the internal electrode layer. Therefore, an oxide component, which increases a melting point of a liquid phase generated at high temperatures by reacting to the component in which TiO2 exceeds BaTiO3, is included in the internal electrode at minimum 5% and maximum 30% in volume. By this method, a low-permittivity secondary phase is prevented from being generated on the interface of the internal electrode layer and the dielectric layer, with a capacitor being increased.

Title: Idle rotation control method
Inventor: ISOBE TOSHIAKI
IPC: F02D41/16
Filed: 1982-12-29
Abstract: PURPOSE:To prevent unstable rotation of engine by performing reduction processing of corrected level for predetermined time when feedback condition has satisfied and target rotation is set. CONSTITUTION:Opening area of an air bypath is controlled to regulate the engine rotation to target level. When feedback condition is satisfied 51 to confirm a flug 53, t1 is set in timer (C) at the step 54. Then prospect level DB is set in duty (D) at the step 56. Processing through steps 51, 53, 58, 59 and 57 is repeated by decrement of timer (C) until said timer (C) goes to zero to hold the opening area of an idle speed control valve ISCV constant. Consequently if the feedback condition is satisfied, rotation can be transferred smoothly even if engine rotation is different considerably from target level.

Title: Pressurization and vibration jig for measuring device
Inventor: YAMADA YUICHI
IPC: G01N3/34
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To enable carrying out of destructive test in a state close to the earthquake force to a mounted sample by a method wherein the sample is attached to a tilted jig so as to be pressurized in a compression direction as well as a pressurization force by a component force in the vertical direction and a pressurization force by a component force in the horizontal direction are applied to the sample. SOLUTION: In a vibration testing device 57, an internal wall is protected by a cushion 58, a vibration base 55 is pressurized, and the rear surface of a sample 54 for vibration is fixed to an inclination member 34 at a vibration jig 21. In this state, a vibration control device 60 is operated, and the vibration base 55 is vibrated. For example, it is assumed that an earthquake force at a gravity acceleration of 1G is applied to the horizontal direction. A vibration force Ax in the horizontal direction is 1G, a vibration force Ay in the vertical direction is at 0, an angle of inclination ψ is set at 0, and an own weight does not act in the gravity direction so as to be remarkably different from a case in which the earthquake force acts on a mounted sample.  As a result, when it is assumed that the vibration force of 1G acts also in the vertical direction, the value of the angle of inclination ψ and that of the vibration force A are given by an expression on the basis of values of the Ax and the Ay which are at right angles to each other. Thereby, when the jig is added to a unidirectional-pressurization compression testing device which is low-cost, a static strength in the horizontal direction can be measured simultaneously.
