Title: Reinforcing structure of optical fiber fusion splicing part
Inventor: IZUMI HITOSHI
IPC: G02B6/255
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To protect an optical fiber and to make the fusion splicing part applicable to the connection of the optical fiber by covering the fusion splicing part with a rigid outer shell, filling adhesive inside and forming an elastic tubular protection layer on the surface of a part of the optical fiber. SOLUTION: A fusion splicing part 2 is covered with an outer shell 9 and adhesive is filled inside the part covered with the outer shell. Preferable adhesive 10 has high viscosity and a high curing speed, the ultraviolet curing adhesive is used for the adhesive 10 and the outer shell 9 is composed of ultraviolet curing glass correspondingly. The outer shell 9 is divided into semi-cylindrical parts 9a, 9b and the cylinder is formed by joining the respective parts 9a, 9b. An elastic tubular protection layer covers the surface of a part out of the end part of the outer shell 9 of the optical fiber 1. Consequently, by exerting the bending stress on the outer shell 9, the bending stress exerted on the fusion splicing part 2 is prevented and the bending radius of the part out of the end part of the outer shell 9 of the optical fiber 1 is restricted by the protection layer 11.

Title: Modulating method
Inventor: ARIMURA KUNITAKA
IPC: H03C1/00
Filed: 1987-07-15
Abstract: PURPOSE:To obtain the simple modulated wave of a modulating circuit by modulating so as to alternately situate the carrier part of a constant amplitude, an amplitude modulated part (AM) part and an amplitude deviation modulated part (ASK) part in time. CONSTITUTION:In an external equipment, the modulated wave on which data is mounted is supplied to the coil of L1. An induction electromagnetic field is formed by a current passing through this coil L1. In a card side, this electromagnetic field is received by a coil L2 to obtain these power and information. In order to obtain the power in the card side, an alternating current voltage induced to the L2 coil by the induction electromagnetic field is fed to a rectifying circuit to rectify and supplied to the respective circuits in the card as a direct current. The data received from the external equipment by the card is obtained by detecting a voltage induced in the coil L2 and inputting it to a comparator to have a digital signal.

Title: Assembly drawing preparing method for regular sending press metallic mold
Inventor: TAKEGAWA YUJI
IPC: G06F17/50
Filed: 1988-07-15
Abstract: PURPOSE:To prepare a correspondent assembly drawing regardless of a direction in which materials are sent by preparing a drawing to invert a temporary assembly drawing when the real material sending direction is reverse to an assumed sending direction and determining this drawing as the assembly drawing of a regular sending metallic mold. CONSTITUTION:The materials are assumed to be sent in a prescribed direction and the layout drawing of the metallic mold is prepared. Then, based on this layout drawing and data to be stored in a memory, the temporary assembly drawing is prepared. When the real material sending direction is coincident with the assumed sending direction, the temporary assembly drawing is determined as the assembly drawing of the regular sending press metallic mold. When the real material sending direction is reverse to the assumed sending direction, the drawing to invert the temporary assembly drawing is prepared and this drawing is determined as the assembly drawing of the regular sending press metallic mold. Thus, when the sending direction of the materials is reverse to the direction of the temporary assembly drawing, only by inverting the temporary assembly drawing, the assembly drawing can be prepared to correspond to material sending in the reverse direction.

Abstract: PURPOSE:To provide a stable magnetic characteristic to a change with the passage of time and a processing error and to have a core structure with a good yield by making the surface opposite to the insulating film of a block nonparallel to the insulating film and extending a first magnetic film to both sides of the block along the border with a pair of nonmagnetic material parts and the block. CONSTITUTION:The head has an alloy magnetic material film 2 as the first magnetic film having a high saturated magnetic flux density such as 'Permalloy(R)', 'Sendust(R)' and 'Amorphous(R)' film-formed, for example, by a physical vapor deposition such as a sputtering on a high magnetic permeability material block 1 and a high magnetic permeability material 1 such as a single crystal ferrite. The border of a magnetic metallic film 2 and the high magnetic permeability material block 1 is nonparallel to a gap 7, a gal length, consequently, a core tip part border line to regulate a track width is approximately parallel and the magnetic metallic film is extended at both sides of the block 1 along the border of the block 1 and a glass 6.

Title: Box-type pallet
Inventor: TSUJI TADAO
IPC: B65D19/12
Filed: 1993-07-15
Abstract: PURPOSE:To prevent an open/close door from being deformed by locking the door to right and left sidewall sides by a locking device in a closed state and inserting engaging members to both ends of the door from an open/close direction. CONSTITUTION:By inserting a bar bolt 33 into a through hole 32 of a staple 31, a lower positioned open/close door 9 is fixed to left and right sidewalls 5, 6 an a closed position. A staple 35 for preventing lateral shift attached to a lower part on the front end of the sidewalls 5, 6 is inserted to both ends of the door 19 to have them engaged. When numerous items are housed into a pallet, each sidewall is pushed by internal pressure F from inside to outside by the housed items. Since the staple 35 for preventing lateral shift is engaged with both ends of the lower positioned open/close door 19 in a closed state at this time, the door 19 is fixed in a lateral direction, so that swelling outward of a center of the door 19 can be reduced. Therefore it is prevented that both sides of the door 19 may be shifted toward the center by the internal pressure F, the bar bolt 33 of a lower locking device 28 may be removed from the through hole 32 and unlocking may occur spontaneously.

Inventor: SAKAI KOUICHI
IPC: H02K3/51
Filed: 1980-12-12
Abstract: PURPOSE:To inhibit deformation due to centrifugal force rationally, and to eliminate the waste of a material by increasing thickness toward a nose of a coil end and making the thickness of the nose section the threefold or more of the core side when a binding wire is wound on an outer circumference of the coil end.

Title: Magnetic disk device
Inventor: HATTORI SATORU
IPC: G11B19/04
Filed: 1990-07-03
Abstract: PURPOSE:To prevent the destruction of data due to relative thermal dislocation between a magnetic head and a magnetic disk by controlling a cooling device at a temperature in a head disk assembly or stopping a starting operation. CONSTITUTION:The cooling device 4 is started after the temperature of the head disk assembly 60 rises more than a prescribed value when the magnetic disk device is raised. When the temperature in the head disk assembly 60 is shifted from a designated range while a magnetic disk device-side is operated, the cooling capacity of the cooling device 4 is increased or decreased and the temperature of the head disk assembly 60 is controlled so that it is maintained within the prescribed range. When the temperature of the head disk assembly 60 is beyond the prescribed range at the starting of the magnetic disk device, the starting operation of the magnetic disk device is stopped and effect that the temperature is abnormal is informed to a host device. Thus, the instability of write/read operations due to a relative thermal dislocation quantity between the magnetic head and the magnetic disk due to a temperature change is cancelled and waiting time can be shortened.
