Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser module capable of stably controlling the optical output. SOLUTION: A semiconductor laser module 1 comprises a semiconductor light emitting 2 having a light reflective plane 22 and a light emitting plane 23 mutually opposed through an active region 21, and an optical fiber 3 which is optically coupled with the light emitting face 23 of the element 2 so as to mutually enable incidence and emission and contains a diffraction lattice 33 for reflecting lights only at a specified wavelength. In generates a light at the active region by the current injection into the light emitting element 2 and reflectively amplifies the light between the reflective plane 23 and the diffraction lattice 33 to output a laser beam.  The reflection wavelength bandwidth of the diffraction lattice 33 is set to a value larger than the wavelength spacing of the longitudinal mode of the light resonant between the reflective plane 22 and emitting plane 23 of the light emitting element.

Title: Optical disk device
Inventor: SUZUKI YOSHIAKI
IPC: G06F3/06
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To secure a maximum difference in processing progress among individual head circuits and to suppress the damage to recorded data to a minimum by making the head circuits perform seek synchronously with one another, obtaining a recording/reproducing address based on a counting amount of the counting circuit of a data transfer amount from a recording start when an error occurs and resuming recording/reproducing. SOLUTION: Since the simultaneous finishing of seeking is not guaranteed even if the seeking is simultaneously started for a plurality of head circuits 2, a time difference occurs in operation among the head circuits 2. In order to keep this time difference within a certain range, a seek synchronizing circuit 23 outputs a seek completion signal 36 to a control circuit 7 after the seeking of all the circuits 2 is finished. A maximum difference in processing progress is guaranteed among the individual circuits 2 and the lower limit of a data transfer speed is secured. Then, when an error occurs, the recording/reproducing address of the counting circuit 8 of a data transfer amount is obtained, and by resuming recording/reproducing, the damage to recorded data is limited to a minimum.

Title: Manufacture of optical fiber coupler and optical fiber coupler
Inventor: MIMURA MICHIHIKO
IPC: G02B6/28
Filed: 1995-04-11
Abstract: PURPOSE: To attain cost reduction by forming respective optical axes of a joint part of one pair of polarization plane reserving fibers in different shapes and to dispense with the alignment of optical axes of optical fibers. CONSTITUTION: Optical fibers 1, 2 consisting of one pair of polarization plane reserving fibers are joined each other to one body shape to become branched shapes and the sectional shapes of the joint part 3 are constituted so that axes of polarizations (optical axes) are different each other. Consequently, when the optical fiber 1 of one side is made to be a linearly polarized light, the axis of the polarization of the optical fiber 2 of other side is made to be declined by 45 deg. at maximum.  When the linearly polarized light is made incident as an incident light 5, the exit light 6 of one side is a linearly polarized light and the exit light 6 of other side becomes a circularly polarized light and when it is taken out by a polarizer inclined by 45 deg. with respect to the optical axis of the fiber, the output is made to be one 2<1/2> th of the output of one side to become a 70% light quantity. The downing of the light quantity is an irreducible sufficient amount in an interference sensor (an optical fiber gyro) and is in a range capable of maintaining a light receiving body arrival light quantity by varying a light emitting quantity by the injecting current of a semiconductor laser.

Filed: 1993-03-19
Abstract: PURPOSE:To realize a dust core having high magnetic permeability at a low cost by mixing a solid organic lubricating agent with ferromagnetic metal grains at the normal temperature for performing flattening. CONSTITUTION:Flattening processing is performed on Fe grains prepared by a water atomizing method by a dry ball mill. At this time, camphor is used as an organic lubricating agent for mixing it 0.05 to 2wt.% to Fe grains 100wt.%. Continuously, Fe grains 100wt.% is kneaded with water glass 1.5wt.% and glass powder 1.5wt.% for being made a core material without removing organic lubricating agent. The obtained core material is compression formed for obtaining a dust core in the toroidal shape. Thereby, the core prepared by adding organic lubricating agent at the time of flattening processing has higher magnetic permeability than an additive-free core.

IPC: H01L21/302
Filed: 1989-04-05
Abstract: PURPOSE: To manufacture a high-performance semiconductor device in which layers having different chemical compositions are homogeneously formed and joined with each other in excellent states by changing the course of substrates continuously passed through a plurality of chambers and the arrangement of the chambers in accordance with the alteration of the course. CONSTITUTION: A supply reel 12 and take-up reel 16 constitute a drive means and intermediate idler reels 20, 22, 24, and 26 constitute a guide means. When such a variable as the impurity, the other component of a reactive gas, the arranging order of chambers between a supply section 14 and take-up section 18 is changed, the arrangement of layers in the cross section of a semiconductor also changes accordingly. In such a continuous vapor-deposition method that an intrinsic layer (I-type layer) vapor-deposition chamber 30 is considerably longer than a P- or N-type layer vapor-deposition chamber 28 or 32, a film substrate 10 advances to the take-up reel 16 from the supply reel 12 at a substantially constant speed.  Since an N-type layer, an intrinsic layer, and a P-type are continuously vapordeposited on various parts of the advancing film substrate 10, the thickness of the layer which is the function of the time spend in an arbitrary chamber decides the relative length of the chamber.
