Title: Boxing device for fruit
Inventor: SHIMOMURA TAKAMICHI
IPC: B65B25/04
Filed: 1989-12-28
Abstract: PURPOSE:To prevent scratches and bruises, etc. on the surface of fruit, due to the fall at the time when fruit are loaded in a box from happening by a method wherein a titling device, which tilts a box from a horizontal position, where one inner side wall surface of the box is horizontal with respect to the carrying surface of a conveyor, to a standing position, where the opening surface of the box faces up, is equipped. CONSTITUTION:A large quantity of tangerines K which are continuously carried by a carrying belt 2 are loaded in a box 3 which is tilted at a horizontal position, by rolling down the tangerines K in the horizontal direction. In the meantime, the loading weight of the tangerines K to be loaded in the box 3 is measured by a measuring instrument 5, and by operating a pulse motor 18, a tilting table 14 is tilted in proportion with the increase of a loading weight which is measured by the measuring instrument 5.

Title: Laser oscillator
Inventor: TADAKUMA MASATERU
IPC: G02F1/35
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To output high-power single longitudinal mode laser applicable to optical communication by including a second optical transmission line containing a laser amplifying medium that is stimulated by residual stimulating light and is thus capable of optically amplifying laser light. SOLUTION: An optical resonator 3 consumes only part of stimulating light emitted from a stimulating light source 4 because of its short Er-doped fiber 1. When the rest of the stimulating light is input as residual stimulating light together with laser to a light amplifier 12 in the next position, one 13 of two wavelength-division multiplexing directional couplers separates the laser and the residual light. The laser beam is directed into a Er-doped fiber 5 and the residual stimulating light is directed into an optical fiber 5. The other wavelength-division multiplexing directional coupler 14 launches the residual stimulating light, launched into the optical fiber 15, into the Er-doped fiber 5 inversely with the laser.  As a result, in the light amplifier 12 the laser input is propagated to the Er-doped fiber 5 excited by the residual stimulating light, and is thereby optically amplified. This makes it possible to output tens of mW of laser light in the single mode.

Title: Dust bag fixing ring
Inventor: FURUKAWA TOMIYOSHI
IPC: B65B67/12
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To house a dust bag in a refuse bin without being bulky and prevent the dust bag from being fallen into the refuse bin even when it is deep by turning the dust bag to be mounted on the refuse bin by a ring to fix it, and further using a ring hook as occasion demands. SOLUTION: By use of a ring A, the turning of a bag B is performed not by a refuse bin C but by this ring A. This ring A prevents the bag B from being bulky. Even when a slightly heavy dust is put, the weight is added to the ring A to nip the bag B under it, and, therefore, the bag B is never fallen into the refuse bin C. When the ring A is smaller than the refuse bin C, a ring hook D is hooked on the mouth of the refuse bin C, whereby the ring A can be mounted without being fallen into the refuse bin C.

Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To make output torques different, when driving a motor in one direction and in the other direction by setting the generation torque due to the excitation coil of at least one phase from among the excitation coils of a plurality of phases. SOLUTION: Excitation coils 1 and 2 and excitation coils 3 and 4 are subjected to bifilar winding, so that magnetic fields of mutually 180 deg. phase relationship can be created. Then, by making a different electrical resistance and the number of turns between the excitation coils 1 and 2 and the excitation coils 3 and 4, a product AT(ampere turns) of the excitation current and the number of turns at the latter is set to a small value, as compared with the product AT of the excitation current and the number of turns in the former. Therefore, torque generated by the excitation torque 3 and 4 is set smaller than that generated by the excitation coils 1 and 2, thus making output torques, different when driving a motor in one direction and in the other direction.
