Abstract: PROBLEM TO BE SOLVED: To obtain a machine component with high axial strength by forming an central axis member of a rotational axis with a material different from a photo-setting resin and by repeatedly laminating the photo-setting resin at the outer peripheral side, so as to integrally shape the rotational member and the rotational axis. SOLUTION: A metal axis is used as a rotational axis 26, and a photo-setting resin is repeatedly laminated in a predetermined part around it. In the manufacturing method, the rotational axis 26 is attached to a rotational actuator 20 and then rotated, and a shutter 16 is opened to irradiate the laser beam 11. The laser beam 11 is focused in the entire circumference of the metal axis 26 through a reflector 4 and a condenser lens 5, thereby setting the resin. The shutter 16 is then closed again, an X-stage 33 is transferred by the resin width set by the single irradiation and the shutter is the opened again to irradiate the laser beam. This repetition lasts by the dimension (w) is irradiated. A Z- stage driving actuator 9 lowers a Z-stage 18 to lower the metal axis 26 by the thickness (t) of the resin-set single layer, so as to form a second resin layer. Thereafter, the operation is repeated.

Abstract: PROBLEM TO BE SOLVED: To reduce the generation of spurious oscillation by forming electrodes on both the main surfaces of a piezo-electric substrate, forming at least one slit on the end face of the substrate and reflecting main oscillation to parts other than the electrode parts by the slit. SOLUTION: Electrodes 2 are respectively formed on both the main surfaces of the piezo-electric substrate 1 consisting of a lead titanate/zirconate group piezo-electric ceramic material. Thus an energy confinement type resonator is constituted. Then a slit 3 is vertically formed on one end face of the substrate 1 in the vicinity of the center part of the end face. The slit 3 is formed on a position nearest to the electrode 2 out of the end face of the substrate 1. The depth of the slit 3 is set up so that a ratio of the depth to a distance from the end face of the substrate 1 up to the electrodes 2 is 588/1000 and the wide is 0.3mm against the 0.8mm diameter of the electrode 2. Consequently the slit 3 reflects main oscillation leaked from the electrode parts 2 to parts other than the electrode parts 2.

Abstract: PURPOSE:To prevent a car from starting to move reversely to the advance direction of the car on a sloping road by arranging a reverse rotation preventive device composed of a one-way clutch for forward rotation to prevent reverse rotation of an electric motor when a shift lever is in an advance position and a one-way clutch for reverse rotation to prevent forward rotation when it is in a retreat position, on an output shaft of the electric motor. CONSTITUTION:When a shift lever operating position is put in an advance position, a coupling sleeve 14 moves to the left side by a shift mechanism, and stays in a position 14a by an action of a check mechanism 8. At this time, a rotary shaft 11 is joind with a one-way clutch 15 for forward rotation through the coupling sleeve 14, and the rotary shaft 11 and the one-way clutch 15 for forward rotation rotate integrally. Here, when the rotary shaft 11 tries to rotate reversely, since the one-way clutch 15 for forward rotation does not rotate reversely, in the rotary shaft 11, reverse rotation of the rotary shaft 11 is prevented. When the shift lever operating position is put in a retreat position, the coupling sleeve 14 moves to the right side, and stays in a position 14c, and the rotary shaft 11 is joined with a one-way clutch 16 for reverse rotation.

CONSTITUTION:At the time of an angle dislocation, a laser beam 33 is reflected on a reflecting surface 32, becomes a laser beam 33-2 of an angle 2d for a Z axis, a laser beam 34 is reflected by a polarization beam splitter 31, becomes a laser beam 34-2 of an angle 2d for the Z axis in the same way, becomes a synthesizing laser beam 36 and is emitted. Here, respective laser beams 33 and 34 are reflected once which is the same number together. Since the reflecting surface 32 and the polarization beam splitter 31 maintain a parallel relation, the dimension between the laser beam 33-2 and the laser beam 34-2 is maintained to (e) at the time of assembling in the synthesizing laser beam 36 and the relative position to the laser beam 34-2 and the laser beam 33-2 is not changed. Thus, even when reflecting surfaces 31 and 32 of a composite optical element 30 to execute the synchronization generate spatially the misregistration by the thermal expansion, etc., the initial position relation of both beams 33 and 34 can be maintained.

Title: Honeycomb heater
Inventor: ABE FUMIO
IPC: F01N3/20
Filed: 1992-08-18
Abstract: PURPOSE:To improve balance between exhaust purification performance and pressure loss by providing a structural body of a honeycomb heater whose one side of a separated sectional area is 10mm or less in a direction perpendicular to an axis of a through-hole and cell concentration is 100 to 800 cells/inch<2> by loosening thermal stress and preventing generation of cracks. CONSTITUTION:A honeycomb heater is prepared by installing electrodes 3 at two portions of a honeycomb structure whose gas passing diameter 2 provided with slits 1 is 82mm. Fe powder, Fe-Al powder, Fe-Cr powder are adjusted and projection-molded into a honeycomb shape by an organic binder and sintered, to form a cylindrical honeycomb structure whose cells are each square shaped. When one side of the honeycomb structure exceeds 10mm, resistance for thermal shock is deteriorated, an crack or cell deformation is generated. When the cell concentration of the honeycomb structure is less than 100 cells/ inch<2>, heating performance gets insufficient. When the concentration exceeds 80 cells/inch<2>, pressure loss is increased. With such restriction, the honeycomb heater excellent in resistance for thermal shock and exhaust gas purification performance is obtained.

Title: Commodity conveying motor device and commodity carrying device for automatic vending machine
Inventor: OTANI YASUSHI
IPC: G07F11/00
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To improve the stop precision of a commodity conveying body to a target stop position by stopping the supply of power to one motor before power supply to another motor is stopped and short-circuiting a part between contact points when the commodity conveying body is stopped. SOLUTION: When a packet moves to a target stop position at the time of sales, the first and second motors 21a and 21b of a motor device 19 positively rotate. Thus, driving torque sufficient for driving an X module can be secured. When the packet approaches the target stop position, the operation of the first motor 21a is stopped and the contact points 28a and 28a are short-circuited. Thus, braking force applied on the rotary shaft of the first motor 21a can be applied on the second motor 21b in operation which is mechanically connected to the first motor 21 through output shafts 23a and 23b. The first motor 21a is braked while the second motor 21b holds driving torque in operation as it is. Consequently, the motor device can forcedly be decelerated to decelerate the X module.
