Title: Magneto-optical information recorder
Inventor: MIYAJIMA GIICHI
IPC: G11B5/02
Filed: 1986-08-27
Abstract: PURPOSE:To contrive to miniaturize an optical system driver by forming a protection outer frame of a lens body by a ferromagnetic body to concentrate the magnetic flux produced by a bias magnet onto a light beam radiation position. CONSTITUTION:A magneto-optical information recording device is constituted by bias magnetic field generating means 9, 10 provided at the opposite side of an objective lens 5 to a magneto-optical recording medium 1 and applying a magnetic field externally to the magneto-optical recording medium 1 near the focal point of the light beam and a protection outer frame 8 containing the objective lens 5 in its inside, having an aperture 7 transmitting a light beam to a position opposed to the magneto-optical recording medium 1 and at least a part of which is made of a ferromagnetic substance. The lines of magnetic force are concentrated onto a recording part by providing the ferromagnetic substance to the protection outer frame 8 of the objective lens 5. Thus, a bias magnetic field with sufficient strength is obtained without increasing the size and output of the bias magnetic field generating means 9, 10.

Title: Installation of double wheels
Inventor: KONISHI SATORU
IPC: B60B11/00
Filed: 1985-09-11
Abstract: PURPOSE:To reduce noise by installing tires onto the double wheels of a bus, etc. so that the lateral grooves on the side, where the inside and outside tires are set close are shifted by a prescribed phase difference in the circumferential direction.

With such constitution, the noises generated alternately from the lateral grooves 5a and 6a interfere each other and are offset, and the peak value of the noise lowers. Thus, low noise constitution is permitted.

Filed: 1988-08-12
Abstract: PURPOSE:To obtain almost the complete filling of the solder and the complete surface connection by using a clad solder sheet for connection between superconducting wires and a reinforcing material and between the superconducting wires and a stabilizing material and by using the reinforcing material having a stepped ditch. CONSTITUTION:A group of superconductive wires and a stabilizing material are placed in a ditch of a reinforcing material. After putting a soldering material foil into a space between the materials, the whole body is heated and pressed. For the soldering material foil 4, a core 4a which has a higher melting point than that of the solder and is coated on both faces with the soldering material is used. The reinforcing material has a step between an upper portion and a lower portion, with the width w1 of the upper ditch in which the stabilizing material 3 is placed larger than the width w2 of the lower ditch in which the superconducting wires are placed. An opening section of the reinforcing material is opened wide with a side wall section slanted as it goes upward. Also, the depth d1 of the lower ditch of the reinforcing material is made large than the width d2 of the superconducting wire. The coil is heated at the melting temperature of the solder and is pressed vertically and laterally from the outside to overflow the excessive melted solder out of the reinforcing and stabilizing materials. By this method, the spaces between the materials and between the conducting wires are filled completely with the solder and a good connection can be obtained.

As a result, direct clamping is made possible without the necessity of an insulating substrate 1. An eyelet 5 is clamped after being passed through a through-hole of the insulating substrate 1 and a hole opened on a conductive metal bar 3. Then, the eyelet presses the conductive metal bar 3 and etching pattern 2 via the substrate 1, and fixes the conductive metal bar 3. Because a metal bar is fixed on the back side of the insulating substrate and directly connected with the terminal for large current of the circuit part, it is possible to fully expand the contact area.

Title: Optical coupling device
Inventor: MORITA AKIRA
IPC: G02B6/42
Filed: 1993-08-17
Abstract: PURPOSE:To optically couple a light emitting element array and an optical fiber array in a small size and to simplify the alignment by arranging and fixing narrow tubes having the same inside diameter as the outside diameter of optical fibers in V grooves formed in a substrate and inserting optical fibers to narrow tubes to fix them. CONSTITUTION:Narrow tubes 2 having a prescribed outside diameter are fixed to a V-grooved substrate 1 for fiber arrangement which is produced with the precision of mum order by normal anisotropic etching, and optical fibers 3 are inserted to these marrow tubes. Consequently, light emission parts or light reception parts of an optical element 4 are easily aligned in the vertical direction (the Y direction) and the optical element array pitch direction (X direction. Since only alignment in the optical-axis direction (the Z direction) is required though alignments in six axial directions are required in the conventional technique, the time of optical axis adjustment is considerably shortened, and fine adjustment devices such as springs and screws are unnecessary to miniaturize an optical coupling system. Further, the inside shape of each narrow tube 2 is formed to a cone to prevent the light emission part or the light reception part of the optical element 4 from being damaged.

Abstract: PROBLEM TO BE SOLVED: To suppress the changes of noises and white smoke against temperature changes by adding an additional value to the base injection timing corresponding to the engine water temperature to determine the injection timing, and multiplying the base additional value determined by the atmospheric temperature by a correction coefficient determined by the water temperature to calculate the said additional value. SOLUTION: An ECU 10 receiving the output signals of an engine revolving speed sensor 15, an accelerator opening sensor 16, and an atmospheric temperature sensor 17 opens or closes an injector 1 according to the engine operating state during the engine operation. The base injection pressure corresponding to the engine water temperature is determined, and a prescribed additional value is added to the base injection pressure to determine the injection pressure. The base additional value based on the atmospheric temperature is multiplied by a correction coefficient of 0-1 determined by the water temperature to calculate the additional value to be used.  The correction coefficient is increased from 0 to 1 as the water temperature is increased between a first water temperature and a second water temperature, and it is decreased from 1 to 0 as the water temperature is increased between a third water temperature and a fourth water temperature.
