Filed: 1985-09-09
Abstract: PURPOSE:To simplify the cost calculation by omitting each coupling arithmetic or applying the semi-coupling or a coupling to carry out the partial inquiry for cost calculation and then performing the minimum cost calculation. CONSTITUTION:When a command is supplied for coupling of tables A, B and C, three cases are first studied with two tables A and B as follows. That is, (1) the coupling is omitted for the time being and then the coupling is attained, (2) the semi-coupling is performed at first and then the coupling is attained and (3) the coupling is attained from the first. Then a case of the minimum cost is selected among those three cases. When the case (2) is discriminated satisfactory according to the cost calculation, the semi-coupling result A(B) and a table C are studied. Thus, it is discriminated that the case (1) is satisfactory. Finally the coupling results A and C(B) and a table B are studied and the case (1) is discriminated preferable. Thus each case is carried out according to the result of each discrimination.

Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To supply an empty pallet without being disturbed by the discharge of a real pallet and to correspond to the high speed loading. SOLUTION: An elevator 13 is provided with a first elevating mechanism and a second elevating mechanism 62. The first elevating mechanism receives an empty pallet P to be supplied from an empty pallet supply device and descends each time when a box group C supplied from an article group supply device is tiered on the empty pallet. The second elevating mechanism 62 receives the pallet P on the way of tiering before the box C of the prescribed number of tiers is tiered on the pallet P of the first elevating mechanism. And after that, it descends each time the box group C is tiered until the box group C of the prescribed number of tiers is tiered. And it transfers the tiered real pallet P on a conveyer device 14 when the box group C of the prescribed number of tiers is tiered.  Accordingly, the loss time in supplying the empty pallet P is shortened and the empty pallet is supplied without being disturbed by the discharge of the real pallet and to correspond to the high speed loading.

Abstract: PURPOSE:To obtain a U-shaped linear light source type surface light emission device whose luminance is high and whose power consumption is low by using a U-shaped linear light source as a linear light source and arranging a side reflection plate on one side surface of a light transmission plate where the U-shaped linear light source is not arranged. CONSTITUTION:The U-shaped linear light sources 2 are provided on three side surfaces of the light transmission plate 1. The side reflection plate 4 is formed on one side surface of the plate 1 where the light source 2 is not arranged. By arranging the light sources 2 extending over three side surfaces of the plate 1, light is introduced in the plate 1 from three side surfaces thereof. Therefore, the quantity of the light in the plate 1 is increased and the surface light emission whose luminance is high is obtained. Besides, since only one set of electrodes is required, the loss of the electric power of the electrodes is reduced and the power consumption becomes low in comparison with a case that three straight linear light sources are arranged. Moreover, since only one inverter for lighting is required, cost is reduced in comparison with the case that three straight linear light sources are arranged.

Filed: 1991-08-08
Abstract: PURPOSE:To prevent generation of counter flow of ejection gas of a missile by installing an offset whose vehicle side is higher on the surface of a drift board located near the vehicle in a vertical launcher provided with the drift board slanting installed below a launching cylinder when launching a vehicle- mounted missile from a vehicle. CONSTITUTION:A vertical launcher of a vehicle-mounted missile launches a missile 3, rotating a launcher cylinder 4 around a hinge 5 of a vehicle 7 and keeping the cylinder in a vertical state. On the end of the vehicle is slantingly installed a drift board 14 whose one end is mounted with a hinge and whose other end is lowered below the launcher cylinder 4 when it is used. In this case, no attempt is made to flatten the surface of the drift board 14 but to install an offset 15 which is higher on the vehicle side, on the surface of the board near the vehicle 7, which forces the ejection gas 2 of a missile engine to collide with the surface of the drift board 14. When a counter flow 12 is partially generated, the counter flow 12 is checked at the offset 15 so as to protect the launcher cylinder 4 or the like from thermal damage.

IPC: F04C2/18
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To dissolve lowering of discharge, noise and vibration caused by suction resistance of liquid. SOLUTION: Suction side opening parts 9b, 14b of side plates 9, 14 sealing the side face leakage of a gear pump are formed in approximately trapezoidal shape composed of two lines L1, L2 proceeding toward the center P1, P2 of both gears from positions where the tooth tips of both gears come in contact with or in closest proximity to a body on the suction side, and a straight line L3 parallel with a line connecting the center P1, P2 of both gears, passing the tooth bottom circles of the respective gears and a position where the teeth of both gears are separated. It is therefore so constituted that the tooth bottom is exposed from the side plates 9, 14 or almost coincides with the tooth bottom at least once in the course of each tooth bottom of the gear passing the suction side opening parts 9b, 14b in the side plate.  As a result, a fluid from the side faces of teeth flows into tooth spaces 4f, 5f without being shielded by the side plates 9, 14, so that suction resistance is reduced.
