Title: Method and device for inspecting magnetic head having magnetoresistive element
Inventor: TOMITA KATSUHIKO
IPC: G11B5/455
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To exclude influence from the outside of an MR element as much as possible by changing a magnetic field to be impressed upon the MR element in changing a sense current and measuring a change of a terminal voltage of the MR element corresponding to a change of the magnetic field. SOLUTION: First of all, positional adjustment is performed between input and output terminals of the MR element to be inspected on a head block 10 fixed on a mounting base 11 of an X-Y-Z-θ table 12 and probe pins 15. Then, an arbitrary waveform generating device 20 is instructed to generate a current specified as to what frequency and how continuous waveform to have. Subsequently, application of the current is instructed to be commenced. Thus, the sense current is impressed upon the MR element of the magnetic head to be inspected from a current power source 19. Consequently, the magnetic field is generated, and the MR element itself is acted by a change of the magnetic field to alter its resistance.  When a voltage from this MR element is filtrated by a frequency filter 21, a low frequency changed component of the terminal voltage is removed, and only a noise component is displayed on an oscilloscope 22.

Title: Manufacture of angle material
Inventor: FURUTA OSAMU
IPC: B21D5/08
Filed: 1989-11-17
Abstract: PURPOSE:To make the interior material in contact with the inside of the angle material without clearance by bending the metal plane material in nearly right angle, locally heating the inner angle corner, pressing and bringing the inside wall of circular arc type recessing relief part to the inner side of the virtual intersection of each inside surface extension line. CONSTITUTION:The manufactured angle material 1 has the circular arc type recessing relief part 103 at its inner angle part 102. And the inside wall of recessing relieve part 103 is positioned more inner side than the virtual intersection K of the extention lines 111, 112 of the inner angle side surface 110, 120 of both the side parts 11, 12 of the angle material 1. Therefore, the inner angle part 102 of the angle material 1 can be brought in contact with the outer angle part of right angle 81 of the interior material 8 and both are able to be in contact with each other closely. In this time, the clearance between both is not generated because the outer angle part of right angle 81 of the interior material 8 is entered inside the recessing relief part 103 which is formed at the inner angle part 102 of the angle material 1.

Title: Method for working end face of optical fiber
Inventor: TSUJII HIRAAKI
IPC: G02B6/10
Filed: 1987-11-27
Abstract: PURPOSE:To enable the working of only the core part to a projecting shape by applying a photoresist on the polished front end face of an optical fiber and projecting light for exposing to the optical fiber from the other end face so that the core part is selectively exposed. CONSTITUTION:The photoresist 5 as a mask for etching is applied on the end face 4 to be worked of the optical fiber. The incident light 6 on the core part 8 is propagated and only the core part 8 of the photoresist 5 at the end face to be worked is exposed when the light 6 is projected in this state on the other end face of the optical fiber 1. On the other hand, the incident light on the clad part is mostly scattered and attenuated and the photoresist 5 of the clad part is not exposed at the end face to be worked. The photoresist 5 is, therefore, left only in the core part 8 when a negative type is selected for the photoresist 5. Only the core part 8 is thus worked in self-alignment to the projecting shape.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a means to pack a PDU according to a status of a host memory that re-configures a received ATM cell into the PDU and saves it. SOLUTION: The controller optimizes the use of a hardware resource and a CPU resource especially such as a host memory space and I/O bus band width, a host memory band width and a memory system band width.

Furthermore, a plurality of status bundles are packed to the host memory buffer to use a memory efficiently. Another advantage to pack and link information is to save a CPU resource by allowing a CPU to link information to be accessed to an adjacent memory area.
