Abstract: PURPOSE:To allow optical axes to be accurately aligned by arranging an electrode wiring formed on the bottom of a clearance for accommodating a semiconductor layer in an opposed relation to an electrode of a semiconductor laser, aligning and holding the optical axes of an optical oscillation region and an optical waveguide, and firmly bonding the electrode wiring and the electrode by a plating method. CONSTITUTION:A semiconductor laser 3 is inserted into a clearance 6 for accommodating a semiconductor laser provided within an optical path of an optical waveguide 7 disposed on a substrate 2. In this case, an electrode wiring 4 provided at the bottom of the clearance 6 is opposed to an electrode 36 of the semiconductor laser 3. Then, the axes of an optical oscillation region 39 of the semiconductor laser 3 and an optical waveguide 7 are aligned and held. Under this condition, both the semiconductor laser 3 and the substrate 2 are immersed in a plating solution and d.c. power is applied between the plate electrode of the plating solution and the electrode wiring 4 on the substrate 2. As a result, the electrode wiring 4 is gradually plated by an electric field plating method, and finally both the opposed electrode 36 and electrode wiring 4 are integrally secured. Accordingly, the optical axes of the optical oscillation region 39 and the optical waveguide 7 can accurately be aligned without contaminating the optical oscillation region 39 of the semiconductor laser.

Title: Multi-color electrophotographic device
Inventor: YOSHIKAWA MASAO
IPC: G03G15/02
Filed: 1987-05-11
Abstract: PURPOSE:To uniformize respective electrostatic charges over a long period of time so that good images are formed by adopting the constitution in which secondary and ensuing electrostatic chargers induce the ions formed by the creeping discharge generated on the surface of a dielectric material or the circumferential end parts of electrodes by an AC voltage of the surface of a photosensitive body. CONSTITUTION:The secondary electrostatic charger 4 provided between primary and secondary developing devices 2 and 3 is embedded with the embedded electrodes 42, 43 in the dielectric material 41 and is discharged with electricity near the electrodes when the voltage above the prescribed discharge initiation voltage is impressed between the two electrodes by an AC power supply 45. The ions of the desired polarity among the discharged ions are extracted to the photosensitive body 1 upon impression of a bias voltage to a bare electrode 44 by a power supply 46. Since the electrodes 43, 42 are embedded, the equal discharge is stably executed irrespectively of the staining in the charger 4. Suspended matter is shaken off by the AC electric field and is adhered to an outside region 48. The good multi-color print having no unequal densities and band-shaped image stains is thus formed.

Title: Multistage axial blower
Inventor: KAWAI SUEO
IPC: F04D19/02
Filed: 1979-09-05
Abstract: PURPOSE: To prevent the occurrence of noises and broaden the range of flow rate applied by a method wherein the flow rate at the starting point of hydromechanical instability of blade wheels at the 2nd level and after is set apart from that of the preceding stage by a certain quantity.  
     CONSTITUTION: The flow rate at the starting point of hydromechanical  instability of a blade wheel 2 at the 2nd level is set apart from that of the blade wheel 1 at the 1st level by 10% or more. For instance, as the blade wheel 1 at the 1st level, the type of a blade which has a large curvature and a large lift coefficient is used, while, as the blade wheel 2 at the 2nd level, such a type of a blade that has a small curvature and a small lift coefficiency is used, and thus the starting point of instability of the blade wheel at the 1st level is transferred to the point of lower flow rate than that of the blade wheel at the 2nd level. In this way, the vibration stress of the blade wheel at the 2nd level lowers by about 60%, while the reliability in strength of the blade wheel is rasied to a great extent, the level of noise is lowered, and accordingly, the expansion of the range of the flow rate applied becomes possible.

Title: Electromagnetic flow coupler
Inventor: AOYAMA GORO
IPC: H02K44/12
Filed: 1991-05-17
Abstract: PURPOSE:To provide an electromagnetic flow coupler whose performance does not deteriorate even to a range where the flow speed is high. CONSTITUTION:In an electromagnetic flow coupler, which comprises a plurality of flow passages 1 and 2 arranged in parallel, an electric conductor 5 surrounding these passages 1 and 2 and circulating a current, and a magnet 8 arranged opposite outside the electric conductor 5, with these passages 1 and 2 between, the magnetic field generated by this magnet 8 is distorted by the magnetic field generated secondarily by a current 6. This distortion works to intensifies the magnetic field, in the vicinity of the end of the magnetic field by the magnet 8 and besides in the direction of the downstream of the fluid (the passage 1 on generator side) driven from outside, so this distorted magnetic field can be utilized effectively by so arranging the electric conductor 5 as to jut out of the magnet 8 along the passages 1 and 2. As a result, the efficiency as the electromagnetic flow coupler becomes high, and besides the higher the flow speed is, the larger the distortion of the magnetic field is, so this effect also becomes larger.

Abstract: PURPOSE:To realize the miniaturization of a precision angle displacing mechanism, the improvement of the rotational motion performance of a movable part, and the saving of energy by connecting two coils so that they generate electromagnetic forces in the directions opposite to each other when a current is flowed in the coils. CONSTITUTION:When magnets 4a, 4c of a magnetization direction 8a and the magnets 4b, 4d of the magnetization direction 8b are fixed respectively to a yoke 5, the magnetic flux of the magnet 4a forms a magnetic field in space including the coil 3a toward the magnet 4b, and similarly, the magnetic field is formed between the magnets 4d, 4c. When the coils 3a, 3b are energized in the directions opposite to each other, the electromagnetic force in the direction of an arrow mark 9a is caused in the coil 3a, and the electromagnetic force in the direction of the arrow mark 9b is caused in the coil 3b, and torque around an axis parallel to the center of the rotation of the movable part is generated. Thus, since the electromagnetic forces of the same intensity are generated, the coil acts effectively, and the coil can be made small and light in weight, and supply power to the coil can be made small.
