Title: Generating method for plural hologram optical system
Inventor: IWATA NARITAKE
IPC: G03H1/04
Filed: 1989-09-19
Abstract: PURPOSE:To prevent the deterioration of the performance caused by an error of a fitting position between holograms at the time of setting a position of plural pieces of holograms by the constitution for generating a wave front obtained by reproducing a first hologram and a second hologram by bringing a second hologram photographic plate to interference exposure by a reference wave front. CONSTITUTION:For instance, a reference wave phi1 and an object wave phi2 are radiated onto a first hologram photographic plate 21 for forming a first hologram, and a first hologram H1 is generated by a holographic exposure method. This first hologram H1 is attached to a jig for maintaining and fixing a position relation to a second hologram photographic plate 31, a reproducing wave phi3 is radiated, and by its transmission diffracted light and a new reference wave phi4, the photographic plate 31 is brought to holographic exposure. In the case a third or subsequent hologram exists, it is generated successively thereafter by executing the holographic exposure by a light beam which passes through the previous hologram and a new reference wave front. In such a way, the deterioration of the performance caused by an error of a fitting position between the holograms at the time of setting a position of plural pieces of holograms can be prevented.

IPC: B65H29/16
Filed: 1987-09-28
Abstract: PURPOSE:To reduce the moment of inertia and eliminate the waste of space in the vertical direction of the whole device by providing a workpiece lifter member whose bendable end arm is linked to a body arm. CONSTITUTION:As a chain is moved upward due to the rotation of a longitudinal type rotary conveyer, a first cam follower 55 and a third cam follower 63 are guided by an inner guide member 47 while a second cam follower 61 is guided by an outer guide member 49 to move a base plate 53 in the same direction as that of the chain. Since a workpiece lifter member 69 is integrally formed with the base plate 63, the workpiece lifter member 69 on which a workpiece is placed is lifted upward. And, when a link plate 57 is oscillated with a pin 59 as a fulcrum, a link block 81 is also oscillated. Due to the oscillation of the link block 81, a connecting plate 77 is oscillated via a link shaft 83 to bend an arm 73 from a body arm 71.

Title: Injection compression molding
Inventor: SATO KAZUTO
IPC: B29C45/50
Filed: 1986-10-09
Abstract: PURPOSE:To prevent the internal strain from generating by a method wherein the forward action for compression of a movable mold is started when a screw during its injection and filling reaches an arbitrary set predetermined position in its injection stroke. CONSTITUTION:In an injection compression molder 1, a screw 2 can axially move back and forth by an injection cylinder 3, and at the same time is installed to a heating cylinder 5 so as to be rotated by a hydraulic motor 4. A movable mold 6 mounted on a movable plater 7 is moved back and forth by a mold clamping cylinder 8 so as to form a molding cavity 11 by engaging with a fixed mold 10. In molding operation, a mold closing is done leaving compression allowance (delta) unclosed in advance, and molten resin is filled in the cavity 11. During filling, when the screw 2 reaches a screw position set by a setter 15, for example, a solenoid relief valve 31 is controlled by the pressure set on a pressure setter 27 so as to change over a solenoid selector valve 30 to the position B in order to perform the compression by the movable mold 6 with the mold clamping cylinder 9. Accordingly, compression action is applied to the molten resin filled in the molds before it is cooled and set, resulting in preventing the internal strain form generating.

Title: Rotating speed detecting mechanism
Inventor: MITAMURA MASAHIRO
IPC: G01P3/487
Filed: 1983-12-23
Abstract: PURPOSE:To accurately detect a rotating speed by constituting a speed detecting conductor in a symmetrical shape to cross to cancel a leakage magnetic flux component from a drive coil, thereby reducing a noise. CONSTITUTION:A speed detecting conductor 112 of a motor rotating speed detector is circulated counterclockwise in a region (a) from a point (d) to a point (e), and subsequently circulated counterclockwise in a region (b) from the point (e) to a point (f). Thus, the signs of induced voltaged due to leakage magnetic fluxes phia, phib from a drive coil are opposite to each other and generated in a direction to cancel each other. Further, since a magnetic flux phic of a region (c) does not cross the conductor 112, the induced voltage is zero. When the regions (a), (b) are so formed as to have the same area for the drive coil and a symmetry, the induced voltaged due to the magnetic fluxes phia, phib become equal to each other.

IPC: B60L50/16
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of a battery by equipping a battery controller with a charging/discharging control means which allows only discharge, until the remaining capacity of the battery computed by a battery's remaining capacity computing means becomes the battery usable lower limit value of able, and inhibiting charging until the temperature of the battery lowers. SOLUTION: Remaining capacity of a battery is computed inside a battery controller 9, referring to the voltage of the battery, charging and discharging currents, and the temperature of the battery. The battery controller 9 controls charging and discharging quantities of the battery, on the basis of the remaining capacity. Battery control is divided into a charge inhibited region, a discharge inhibited region, and a use permitted region. The remaining capacity of the battery is computed or displaced by voltage detection of the battery or the integration of current of charge and discharge in a battery's remaining capacity computing part 91, and its result is outputted to a charge/discharge control part 92. The control part 92 controls the current of charge and discharge, limiting the range of the remaining capacity of the battery.  Consequently, the temperature rise of the battery and its deterioration can be prevented.
