IPC: H04B10/564
Filed: 1990-03-27
Abstract: PURPOSE:To prevent an extinction ratio from being deteriorated even when a laser diode whose inclination of an I-L curve is changed by a temperature characteristic is used by a method wherein not only a DC bias current but also a modulating current is changed so as to match the temperature characteristic of the laser diode. CONSTITUTION:An optical output power is adjusted by using variable resistances RV1, RV2; the dividing ratio of a DC bias current to a modulating current is adjusted by using a variable resistance RV3. Error amplifiers IC1, IC2 are controlled in such a way that voltages at negative input terminals are respectively equal to Vr1, Vr2; the optical output power is made definite. Then, when a diode RC1 does not exist at a temperature of t=T2 (however, T2>T1), the ratio of monitoring currents IM1, IM2 flowing in Tr5, Tr6 becomes definite. The diode RC1 is added and a temperature characteristic is given; the current flows to the Tr6. When the value of the monitoring current IM2 is increased and the ratio of IM1, IM2 is changed, the DC bias current and the modulating current can be set to IDC3, IAC3.

Title: Manufacture of laminated electronic part
Inventor: KAMIYAMA YOSHIAKI
IPC: H01G13/00
Filed: 1991-01-21
Abstract: PURPOSE:To simplify the method of removal of noise, which is generated in f-Q (frequency-quality factor) characteristics when the outer electrode of chip inductor is formed by barrel electroplating, by demagnetizing magnetic material provided on the inductor. CONSTITUTION:The electrifying current for a plating bath is gradually attenuated almost to zero in the finishing stage of current application in a barrel electroplating operation. As a current can be allowed to flow on the chip inductor which moves in the barrel in a freely inverting manner in the same probability in forward and reverse directions, magnetic material can be demagnetized by gradually decreasing the current to zero in the same principle as the AC demagnetization, and this can be accomplished by a simple change of a barrel electroplating process.

Title: Nonaqueous electrolyte battery of cylindrical form
Inventor: FUJITA KOJI
IPC: H01M50/531
Filed: 1987-03-31
Abstract: PURPOSE:To improve attachment strength between a negative electrode and a negative electrode current collecting plate and eliminated an internal shortcircuit by the negative electrode current collecting plate by forming tongue-like protrusions in the negative electrode current collecting plate which is overlapped with one end of the belt-like negative electrode composing a group of spiral electrodes. CONSTITUTION:In a negative electrode current collecting plate 1 are formed six, for example, of tongue-like protrusions 2 of a semicircular form in two lines facing their root parts with each other at its overlapped part with a negative electrode 3. If the negative electrode current collecting plate 1 is pressure attached to one end the negative electrode 3 composing a spiral electrode group, then the tongue-like protrusions 2 bite the negative electrode 3 to be embedded. A sufficient attachment strength can thus be obtained. However, because the forward ends of the tongue-like protrusions 2 are not sharp, the tongue-like protrusions 2 will not penetrate a separator if the negative electrode 3 on the negative electrode current collecting plate 1 is consumed to be thin.

Abstract: PROBLEM TO BE SOLVED: To enable long distance transmission of a large output laser beam that remains stable for a long time by controlling temperature distribution inside a mirror in the transmission system of a laser welding equipment and thereby preventing diffusion of the laser beam. SOLUTION: The neighborhood of the rear surface of the mirror is heated so that a reverse camber takes place that may balance or exceed a camber due to the temperature rise on the mirror surface, with the temperature distribution controlled on the side cross section of the mirror. For this purpose, while the mirror 1 surface (reflecting surface) is cooled with a cooling passage 2 provided, the mirror 1 rear surface is heated to about 30-40 deg.C by a heater 4 provided discretely on the rear side or by a hot water passage 5 provided just beneath the rear surface of the mirror 1 where hot water of about 30-40 deg.C is made to flow. Otherwise, a cooling gas such as air or an inactive gas is injected from a nozzle 3 to the center surface of the mirror 1, cooling the center surface and making its temperature lower than that of the rear surface.  As a result, diffusion of a laser beam can be prevented in the mirror in a high output laser transmission system.

Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a resonance-mode grating filter capable of improving polarization dependence when an incident light comes in tiltingly to a grating surface, by providing a grating layer having a two-dimensionally arrayed grating structure and symmetrizing wave-number vectors of a plurality of resonance lights for an incident surface of the incident light. SOLUTION: This resonance-mode grating filter is provided with a grating layer 1, a wave-guide layer 2, and a substrate 3. The wave-guide layer 2 is formed on the substrate 3, and the grating layer 1 is formed on the wave-guide layer 2. An incident surface P of an incident light I coming in inclined by an angle θ in relation with an orthogonal direction to the grating layer 1 is set so that wave-number vectors of two resonant lights are symmetric in relation to the incident surface P and an azimuth (an angle between the incident surface P and one edge of a square of the grating) is 45 deg.. At this time, the incident light I causes resonance via the grating layer 1, and reflected light R with a specific wavelength is reflected. Therefore, polarization dependency can be improved when the incident light I comes in tiltingly to a grating surface.
