Title: Optical coupler for optical isolator adjustment
Inventor: NAITO KATSUYOSHI
IPC: G02B6/42
Filed: 1994-10-27
Abstract: PURPOSE: To take a sufficient distance from a photodetector, to prevent the congestion of adjusting stages, and to improve the workability by constituting an optical coupler, which converts the light converged once to a beam of parallel rays, and a collimator holder which holds this lens. CONSTITUTION: The optical coupler for optical isolator adjustment which adjusts the place of polarization of an optical isolator 5 of a single lens converging optical coupler incorporating the optical isolator 5 consists of a lens 11, which is arranged in a prescribed position to convert light converged once to a beam of parallel rays, and a collimator holder 12 which holds this lens 11. The lens 11 converts the light converged once to a beam of parallel rays, and the collimator holder 12 prevents divergence from the lens 11. Consequently, the light passing the lens 4 is sent to a photodetector 10 without a loss except reflection on both end faces of the lends. Since this light is a parallel beam, the photodetector 10 sufficiently receive it without a loss even if a distance L is long.

Filed: 1987-10-20
Abstract: PURPOSE:To make proper antiskid control possible by judging whether wheels are within a safety domain or not from the value of wheel acceleration, and selecting a control mode according to the result of the above-mentioned judgment to control hydraulic pressure in a braking hydraulic pressure system. CONSTITUTION:The acceleration omega' of a wheel occurring in a controlled system 1 is detected through a detector 15, which outputs the amount Sen1 of information proportional to the detected acceleration as a voltage level. In this case, the detector 15 may have either of types in which the acceleration is directly detected or obtained by differentiating differentiated velocity value. The amount Sen1 of information output from the detector 15 is input in a differentiator 16 and a setting apparatus 17. The differentiator 16 differentiates Sen1 to supply the rate of change DELTARomega'/g obtained there as the amount of information Sen2 to the setting apparatus 17, which then outputs hydraulic pressure regulating signals Z1, Z2 correspondent to Sen1, 2 into a regulator 18, which supplies supplied hydraulic pressure P to an element 5 to generate fixed braking force.

Title: Data recording system
Inventor: ADACHI OSAMU
IPC: G11B20/12
Filed: 1984-12-17
Abstract: PURPOSE:To detect securely the 1st frame synchronizing signal after a preamble value by arranging plural frame synchronizing signals consisting of patterns whose autocorrelation is not sharp in a preamble constituting a data area. CONSTITUTION:The preamble PA1 is costituted by inserting (n) frame synchronizing signals FS into a bit synchronizing signal BS1 at intervals Tf of one frame. A formatter controller 1 generates the preamble PA1 by operating a bit synchronizing circuit 2 and a frame synchronizing signal generating circuit 3 successively (n) times at a period Tf and then operating the circuit 2 once. Then, the controller 1 operates the circuit 3 and then outputs write data for one frame from a data buffer 4; and this operation is repeated by as many times as the total number of frames of a data area to generate signals for one sector. Plural signals FS are arranged in the same preamble, so even if an error occurs to the 1st signal FS arranged right after the preamble, the position of the frame is predictable.

Title: Continuous plating device
Inventor: TAKAGI MASAMI
IPC: C25D17/22
Filed: 1992-10-02
Abstract: PURPOSE:To facilitate production of diversified kinds in small quantities and to enable the perfect automation of plating operations by forming spiral transporting paths on the inner peripheral surface of a cylindrical plating cell and vibrating this plating cell in a circumferential direction and vertical direction by an exciter. CONSTITUTION:The base of the plating cell 1 projects in the central part from the circumference and, therefore, if members A to be plated are fed between the inner periphery of the transporting paths 2 and anode plates 5, the members A to be plated are gathered to the peripheral part of the plating cell by the vibrations in the exciter 10 and are eventually introduced to the transporting paths 2. The members A to be plated are thereafter subjected to the plating treatment while the members are moved above in the transporting paths 2 according to the vibration of the plating cell 10. These members are taken out of the plating cell 1 to the outside through an ejection port 6. The perfect automation of the operations to feed and take out the members A to be plated is thus possible. Further, the members A to be plated fed to the plating cell 1 are taken out without allowing the plating liquid to flow out. The consumption of the plating liquid is thus reduced.

Title: Composite roll for rolling
Inventor: OTOMO SEIJI
IPC: B22D19/16
Filed: 1992-10-02
Abstract: PURPOSE:To improve boundary strength in a continuous tinkering casting method utilizing induction heating. CONSTITUTION:Boundary strength is improved by making the amount of meltdown of a core material 3 to 15mm. When the amount of meltdown of the core material is made into >=20mm, microstructure segregation is generated on the side of the outer layer in the boundary and boundary strength is lowered. On the contrary, when the amount of meltdown of the core material is made into <=3mm, slag biting defect is liable to be generated and boundary strength is decreased. Then, by making the amount of erosion of the core material a proper value, boundary strength is improved.

Filed: 1994-10-28
Abstract: PURPOSE: To provide a phase difference plate of a low cost having reliability of a practicable use level by solving a film peeling which is heretofore a significant problem in a phase difference plate formed by using diagonal columnar structural films. CONSTITUTION: Double refractive films (Ta2 O5 films) 12 having a diagonal columnar structure are formed on both surfaces of a lithium niobate substrate 11. In such a case, the thickness of double refractive films 12 to be formed on the respective surface is made half the thickness of the case where the film is formed on one surface. As a result, the formation of the film on one surface to a smaller thickness is possible and, therefore, the internal stresses of the double refractive films 12 are decreased and the reliability of adhesion of the substrate 11 and the double refractive films 12 is improved. The optical characteristics are similar to the case where the films are integrally formed on the one surface.

Abstract: PURPOSE:To enable nozzles to be jointed at high yield without generation of any clogging during jointing process using strong adhesive by processing the surfacial roughness of a joint to a special range of surfacial roughness values and allowing a required amount of injected adhesive with specific viscosity to penetrate. CONSTITUTION:When jointing a head body of an ink jet printer to a nozzle plate, the wetting and area of an adhesive on the surface 10' of a head body 10 are increased. Further to give an anchoring effect, the surface is roughed to a roughness range of 1.5-6S. Next, the head body 10 is set on a jig and the nozzle plate 11 is placed on the head body 10. An adhesive (p-epoxy resin having viscosity of 20-1,500c) is titrated to a fixed dosage under a condition in which the head body 10 and the nozzle plate 11 are positioned and fixed. Thus the adhesive does not run into microholes on the member of the head body 10, and stops at the edge of the diameter of a head body liquid chamber hole 13. In addition, the member is jointed uniformly without permeation dispersion.
