Abstract: PURPOSE:To enable transfer work without interruption in a storage device with multiple shelf compartments by arranging direct transfer devices on both sides of single-type storage shelves. In case any one of the transfer devices fails, the transfer work can be switched to the transfer device on the opposite side to carry on the work. CONSTITUTION:Vertically movable transfer devices B1, B2... are respectively arranged in parallel with and both in front of and at the rear of storage shelves A1, A2... so that the transfer work for each shelf compartment can be performed with the device on either side of the shelf. The transfer devices B1, B2... are respectively equipped with trouble sensors E1, E2... so that trouble signals are inputted into a control means D. With this configuration, any transfer device is assigned by command from a command means C to perform the transfer work. In case the assigned device, e.g. B1, fails, trouble signal from the trouble sensor E1 is inputted into the control means D to stop the failed transfer device. At the same time, the command means C assigns and gives command to the transfer device B2 to take over the work. Thus, work can be continued smoothly even in case of trouble in one of the transfer devices.

Title: Laminated panel manufacturing machine
Inventor: OKABE TADASHI
IPC: B32B3/12
Filed: 1990-02-02
Abstract: PURPOSE:To enable a large-size laminated panel to be easily manufactured in a relatively small space by using a panel mold consisting of paired molding hemispheres hinged to each other's forming surfaces with the intermediate part on the both sides of each molding hemisphere supported on a guide frame in such a manner that the hemisphere rotates and moves freely. CONSTITUTION:A pair of right and left molding hemisphere MH, MH of a panel mold M are opened apart on the mounting surfaces S of a pit P by traction of traction wires 101, 102, and a gel coating liquid 40 is uniformly applied, as a decorative layer, to the flat forming surfaces 6, 6 of paired molding plates 5, 5. Then the applied liquid is allowed to half-cure to laminate an FRP layer(f). After setting a core 45 on the hemisphere MH, a mold M rotates on its rotating wheels 7, 7 inwardly by its own weight resulting in the mutual approach of the hemispheres MH, MH. Then the hemispheres become folded at a hinge 3, then are locked in the closed position, if the traction power of the traction wires 101, 102 are released. The PRP layer(f) and the gel coat are thermally cured in one piece. After that, the laminated panel is taken out by opening the hemispheres MH, MH apart almost horizontally. Thus it is possible to manufacture a large-size laminated panel easily and especially minimize a space required for the manufacturing machine.

IPC: F25C1/12
Filed: 1990-02-01
Abstract: PURPOSE: To prevent formation of ice slush during ice making cycle by opening a water intake valve to supply water additionally to a water when the water temperature of the receiver drops down to freezing temperature during each ice making cycle and closing the water intake valve during the remaining time of ice making cycle. CONSTITUTION: When the water temperature of a water receiver drops down to freezing temperature, a second water quantity control circuit comprising a thermostat 42a, a thermostat relay R5, a high water level switch 41a and a full water relay R4 operates to supply additional water from a water supply means to the water receiver until the water level increases again up to an initial level to open the switch 41a.
