A drill bit for core boring of the type provided with a multi-layered bit head, so constructed that when the blades of the upper-layered bit head have become worn out, it is possible to easily withdraw them without removing the bit from the bore. The core boring operation is then continued without delay by using the blades of the newly exposed lower-layered bit head. The drill bit is also so constructed that it is possible to eliminate any displacement of the upper layer blades from their fitted position on the blades of the lower layer blades during drilling by using the upper layer blades and at the same time, it is possible to easily disengage the engagement between the bit body and the upper layer blades when the upper layer blades have become worn out.

摘要:
There is disclosed a horizontal type hydrohoist, in which slurry is forced to feed under lower pressure into feed pipes which are connected to a transport pipeline at their one ends and to a high pressure clear water pump at the others, said pump being adapted to deliver clear water under a high pressure, after which clear water is transferred under a high pressure through said feed pipe from said high pressure clear water pump, thereby transferring said slurry. This hydrohoist system presents the provision of means for preventing mixing and its spreading at the boundary portion between slurry and water within the feed pipes. More particularly, a separator which is designed not to rotate during the transfer is inserted in the aforesaid boundary portion in a manner that the separator may be transferred together with fluid, thus preventing the mixing of water with slurry as well as the resultant spreading thereof. According to a further aspect of the invention, at the completion of the slurry transfer under a high pressure, the separator is caused to be gradually slowed down to stop for the purpose of obviating a water hammer phenomenon within the pipings. In addition, after the removal of the slurry remaining around the separator by using a high pressure water, the feeding of the high pressure water is interrupted, thereby preventing mixing and its spreading at the boundary portion of water with slurry at the time of the subsequent introduction of slurry under lower pressure.

A heat pump heating and hot-water system includes a water heating heat exchanger for heating water by heat exchange with a heating medium heated by a heat pump unit, an indoor heating unit, a heating circulation circuit for selectively pumping the heating medium to either of the water heating heat exchanger and the indoor heating unit using a heating medium pump, and a hot-water accumulating circuit that sends water in a hot-water storage tank to the water heating heat exchanger and returns water having passed through the water heating heat exchanger to the hot-water storage tank using a water pump. The volumetric flow rate of the heating medium pumped to the water heating heat exchanger by the heating medium pump is higher than or equal to the volumetric flow rate of the water pumped to the water heating heat exchanger by the water pump.
摘要:
A refrigeration cycle apparatus simultaneously performs a cooling operation mode in which a refrigerant from a compressor is caused to flow to an indoor heat exchanger of an indoor unit having a cooling load, and a hot water supply operation mode in which a refrigerant from the compressor is caused to flow to a water heat exchanger of a hot water supply unit having a hot water supply demand. An operation control part switches the control mode of the simultaneous cooling and heating and hot water supply operation mode between a cooling-prioritized mode and a hot-water-supply-prioritized mode according to the relationship between the cooling load and the hot water supply load.
摘要:
An air-conditioning apparatus, including a refrigerant circuit connecting a compressor, a heat source side heat exchanger, an expansion valve, and a use side heat exchanger in order with a refrigerant piping. A compressor heater is provided for heating the compressor when the compressor is not in operation. A compressor temperature sensor is provided for detecting a compressor temperature. A refrigerant temperature detection sensor is provided for detecting a refrigerant temperature in the compressor. A controller is configured to estimate an amount of liquid refrigerant in the compressor by integrating the temperature difference between the compressor temperature and the refrigerant temperature during a period in which the compressor temperature becomes lower than the refrigerant temperature, and control the heating operation, which is carried out by the compressor heater, on the basis of the estimated liquid refrigerant amount when the compressor is not in operation.

摘要:
In a transcoder, a decoder decodes a stream and an encoder encodes the stream again. The encoder calculates the quantization step value by using an average period bit rate (ASn(M)) of a first stream or an average period bit rate (ACn(M)) of a second stream. Buffers store bit rates (Sn, Cn) of the first and second streams for M periods, respectively. The encoder uses the average period bit rate (ASn(M)) of the first stream or then average period bit rate (ACn(M)) of the second stream in any one of the periods M1, M2 and M3 among M periods.

According to one embodiment, a power supply control device of a plasma processing device having a plasma generation unit which generates plasma in a process chamber. The power supply control device includes a radio frequency power supply, a storage unit, and a matching circuit. The radio frequency power supply supplies a power to the plasma generation unit. The storage unit stores matching information including a first matching value, a second process condition, and a third matching value. The first matching value corresponds to process information of a first process condition. The second matching value corresponds to process information of a second process condition. The third matching value corresponds to process information of a transient state where the first process condition is being switched to the second process condition. The matching circuit matches impedances based on the matching information.
