Abstract: Although a steel plate concrete structure (SC structure) is generally provided with extremely excellent performance in view of the structure, in view of building operation, it is necessary to weld and joint SC steel plate units at a building site. It is an object of the invention to provide a mechanical joint structure of SC steel plate units comprising surface steel plates or surface steel plates and constituent members thereof by omitting field welding which has been needed conventionally in view of a building procedure.

Abstract: There is provided a reactor building of steel concrete construction, which comprises a steel concrete containment vessel constructed on the center of a footing slab and also composed of a pair of relatively confronting steel plates and concrete placed in a space between the steel plates. The reactor building is constructed on the outer circumference of the same footing slab and is also composed of a pair of relatively confronting steel plates and concrete placed in a space between the steel plates. The containment vessel is separated from partial slabs among a plurality of slabs of the reactor building placed around the containment vessel or all the slabs of the reactor building.

Abstract: A processing torch having a separably assembled torch base and torch head includes a first ring member rotatably provided on an outer periphery of one of the torch base and the torch head, and a second ring member fixed on the other one of the torch base and the torch head. An engaging projection is provided on one of the first and second ring members, and an inclined track provided on the other of the first and second ring members for engaging with the engaging projection. In addition, an elastic biasing member is provided for increasing an engaging force between the inclined track and the engaging projection so as to sealingly engage the inclined track and the engaging projection. Connection and disconnection between the torch base and the torch head are performed by rotation of at least one of the first and second ring members.

Abstract: A refrigerating and humidity-regulating system for a container is disclosed, which comprises a refrigerating unit having a humidity-regulating apparatus assembled therein. This humidity-regulating apparatus includes a solid adsorptive material, an air heater, an air blowing means, and an air circulation route for circulating inside and outside air through the air heater and the solid adsorptive material, in that sequence. The solid adsorptive material may be formed as a fixed bed, and inside air and outside air are alternately circulated through the fixed bed. In one preferred embodiment, the above-mentioned humidity-regulating apparatus is assembled in multiple in the refrigerating unit, wherein in each of the humidity-regulating apparatuses the solid adsorptive material is formed as a fixed bed, and inside air and outside air are alternately circulated through the fixed bed in each humidity-regulating apparatus.

Such additional facilities include a container inside temperature detector, a container outside temperature detector, a control responsive to a wrong condition diagnosis instruction for operating an evaporator fan and an electric heater of the refrigerating system, and a wrong condition diagnostic device for diagnosing whether or not a wrong condition of the container is present on the basis of the temperatures detected by the respective temperature detectors after a predetermined period of operation of the evaporator fan and the electric heater.

Abstract: In the self testing refrigerator disclosed, a controller normally controls the operation of various electrical devices, such as a compressor, a blower, and an electric heater by actuating and deactuating separate relays from the power source to each of the devices. During self testing, a switch arrangement disconnects the power source supply and substitutes a high voltage dc generator having a series resistor. The same controller that controls the refrigeration operation of the devices automatically actuates the aforementioned relays separately and successively to apply the high voltage across the terminals of the electric devices and ground. The voltage across the resistor indicates the current flow through, and hence the integrity of, the insulation in each of the devices.

Abstract: A control device for a freezer in which a compressor whose operation has been stopped due to low lubricating oil pressure may be automatically restarted. This control device eliminates manual restarting of the compressor repeatedly until it becomes fully operational and facilitates discovery of the true malfunctioning of lubrication mechanisms for bearings in freezer compressors, by prohibiting automatic restarting once the compressor has been operating at normal oil pressure for a preset amount of time.

Abstract: A refrigeration systems diagnoses its pressure sensors by turning the system off, determining whether the pressure sensors on the high-pressure-side and on the low-pressure-side of a refrigeration circuit detect unvarying pressures, and comparing the pressure values detected by a high pressure sensor and a low pressure sensor with each other. The high pressure sensor or the low pressure sensor is regarded as defective when the difference between the two pressures detected falls outside a tolerance range. In one embodiment an analyzer compares the pressures to produce a signal indicating failure when the pressure difference falls outside the tolerance range.
