摘要:
A controller which controls a refrigerating unit so that a temperature detected by a controlled temperature detector is equal to a setting temperature, includes a memory for storing the temperature detected by the detector, a card data input-output unit for reading data from a card and writing data in the card, a reading unit of the card data from the input-output unit, and a discriminator for discriminating whether the card is a setting card or a recording card on the basis of the card data read from the reading unit, whereby (a) when the discriminator discriminates that the card is the setting card, the setting temperature is set on the basis of the card data, and (b) when the discriminator discriminates that the card is the recording card, the temperature data stored in the memory is read to be written in the recording card through card data input-output unit, so that administration of data such as the setting temperature and the controlled temperature by a computer is attained and wrong setting of the temperature by the operator can be eliminated.
摘要:
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.

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.

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.

A opening and closing device 10 for sunroofs of an automobile, which has a pair of rails 17a and 17b, a lid 13 for opening and closing an opening 12, right and left cables 26 engaged to a lid 14 and arranged along the rails 17a and 17b, and a drive mechanism 36 for driving the cables in a reciprocating manner. The cables 26 construct a closed loop arrangement with bypassing the opening 12 of the loof of the automobile. One of the cable 26 coming out of the drive mechanism 36 is arranged to the right-side rails 17b, bridged to the left side lail 17b, reversed at the base end of the left side lail 17a and returned along the same route to the drive mechanism 36.
摘要:
A stranded wire rope of the present invention is composed of a plurality of wires. The stranded wire rope is subjected to swaging. A mean wire diameter ratio of the plurality of wires is at most 5%, and a wire gap ratio is in a range between 20% and 35% due to sujecting the stranded wire rope to swaging. The mean wire diameter ratio and the wire gap ratio are defined as:mean wire diameter ratio=(d/D).times.100(%)wire gap ratio=(1-(S/A)).times.100(%)whered: mean diameter of each wire,D: diameter of the wire rope before subjecting the wire rope to swaging,S: summation of sectional areas of each of the wires constituting the stranded wire rope, andA: area of circumscribed circle of the wire rope after subjecting the wire rope to swaging.
