摘要： PURPOSE: To obtain a movable-floor elevating device with the simple structure at a low cost by switching normal rotation/reverse rotation of a pump with a control board and controlling the revolution number of a driving motor so as to synchronously elevate rods of plural hydraulic cylinders at the predetermined speed. CONSTITUTION: At the time of raising a movable floor 1, switching valves 6a, 6b are opened, and motors 28a, 28b are operated in the direction for leading the discharged water of pumps 8a, 8b from one side ports 10a, 10b to the other side ports 9a, 9b. High-pressure water is thereby fed to hydraulic cylinders 3a, 3b so as to raise the movable floor 1. At this stage, a control board 27 controls the revolution number of motors 28a, 28b on the basis of the feedback signal from stroke detecting sensors 26a, 26b through motor control units 29a, 29b so as to synchronously raise rods 4a, 4b at the predetermined speed. Thereafter, the motors 28a, 28b are stopped, and the switching valves 6a, 6b are closed so as to hold the movable floor 1 at the stop position.

摘要： PURPOSE:To execute drilling work under stabilized and uniform state by attaching an outer tube to a driving motor of a drilling machine through supports and by jetting water jet through a nozzle. CONSTITUTION:An outer tube 8 is attached to the outside of a driving motor 2 through a plurality of supports 7, and end edge 8a of the outer tube is positioned in front of a nozzle 1. When drilling a bore, water jet 4 is ejected through a nozzle 1 while the nozzle is driven in revolution by the driving motor 2, and a drilling machine A is thrust forward with a propelling device. The drilling machine is moved forward continuously at a speed corresponding to the drilling speed by the water jet 4, and excavated earth is allowed to flow, together with the jetting water, to a bore 6 through a gap between the internal wall of the outer tube 8 and the outer circumference of the driving motor 2, and is furthermore discharged to the outside. Thereby, the drilled bore 6 is made in a uniform size slightly larger than the external size of the outer tube 8, and the drilling is made stably without being influenced by self-weight of the drilling machine even in the case of horizontal drilling.

摘要： PURPOSE:To hold a lifting table automatically at an elevated position by a lifting table holding mechanism comprising an upper and a lower member pivotally joined to the lifting table and a fixed table, a control means for controlling the turning of the upper and the lower member in one direction, and a joint moving means for horizontally moving the joint of the upper and the lower member. CONSTITUTION:When a lifting table 3 is elevated by a lifting means, a joint pin 5a is positioned at a small distance from a vertical line V on the side opposite the side of a stopper bracket 10 with respect to the vertical line V. Then, the operating rod of a cylinder actuator 12 is retracted to turn a lower member 4 clockwise to shift the joint pin 5a to the other side; consequently, an upper member 11 is displaced by a small distance beta and the side surface 1a of the upper member 1 comes into contact with the stopper bracket 10 to hold the members 1 and 4 in positions slightly tilted toward the stopper bracket 10. The lifting table 3 is held at the elevated position even if load L is exerted on the lifting table 3 because the stopper bracket 10 and the members 1 and 4 bear the load L. The cylinder actuator 12 need not apply any force to the lower member 4, which saves power.

摘要： PURPOSE: To reduce the cost of lubrication unit by constructing the pressure oil supply casing for supplying pressure oil to the rotary shaft to be fixed in the rotary direction but to be slidable freely in radial direction.
CONSTITUTION: During when a motor 1 is driven to rotate the rotary shaft 4, said shaft 4 is rotating in static pressure oil supply casing 10 while maintaining a narrow gap. Said casing 10 is formed to be fixed in the rotary direction but slidable freely by the clearance of a knock pin 12 and a hole 13 in radial direction against the foundation 9. Consequently, even upon lateral swing of the rotary shaft 4 due to vibration, the casing 10 to be fitted with said shaft 4 will displace together with the rotary shaft 4. Since the bearing function will never occur even if the gap between the fitting faces is small, there is no possibility of increasing gap due to abrasion of the sliding section thereby the gap can be maintained at the minimum necessary level. Consequently, the circulating amount of working oil is reduced to reduce the cost of the lubrication unit considerably.

摘要翻译：目的：通过构造用于向旋转轴供给压力油的压力油供给壳体，以在旋转方向上固定而在径向上自由滑动来降低润滑单元的成本。构成：当电动机1被驱动以旋转转轴4时，所述轴4在静压油供给壳体10中旋转同时保持狭窄的间隙。所述壳体10被形成为沿着旋转方向固定，但是通过撞击销12和孔13在径向上相对于基座9的间隙可自由滑动。因此，即使由于振动而导致旋转轴4的横摆动作，装配有轴4的壳体10将与旋转轴4一起移动。由于即使配合面之间的间隙较小，也不会发生轴承功能，所以不会由于滑动磨损而增大间隙从而间隙可以保持在最低必要水平。因此，减少了工作油的循环量，大大降低了润滑单元的成本。

摘要： PURPOSE:To provide a water storage tank for operating a hydraulic cylinder of high reliability in the simple structure, where water can be automatically changed and the hydraulic cylinder can be securely operated even in the case of a water failure. CONSTITUTION:An apparatus comprises an inflow port 31 having a constant water level valve 10 and adapted to flow fresh water, a water supply port 16 to a hydraulic cylinder 1, a water return port 17 from the hydraulic cylinder 1, and an overflow port 14 for discharging water outside. The overflow port 14 is positioned above a water stopping level 12 of the constant water level valve 10 and under a water level 21 inside a reservoir tank 7, which is elevated in the case where there is no overflow when water staying inside the hydraulic cylinder 1 returns to the reservoir tank 7. The supply port 16 is located under a water level 13 inside the reservoir tank 7, lowered in the case where water does not flow through the water inflow port 31 when the water staying inside the reservoir tank 7 is fed to the hydraulic cylinder 1.
