摘要:
An auxiliary heater control device can be readily attached to a hot water heating system configured with a simple water circuit without a hot water storage tank, and is capable of preventing freezing of circulating water such that use of an auxiliary heater is minimized. When a sensed temperature tS sensed by a temperature sensor is in a range, a control device increases a rotational speed of a circulation pump. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump and lowers an operating frequency of a compressor. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump, lowers the operating frequency of the compressor, and activates an auxiliary heater.

An object of the present invention is to provide a method and a system by which hydroxycarboxylic acid cyclic dimers are efficiently generated, allowing high yields of high-quality polyhydroxycarboxylic acid to be obtained. The method for synthesizing polyhydroxycarboxylic acid comprises a depolymerization step for depolymerizing hydroxycarboxylic acid oligomers to produce hydroxycarboxylic acid cyclic dimers, wherein, in the depolymerization step, a reaction solution is heated via heat transfer from a heat medium passage under reduced pressure while the reaction solution is being flowing through a horizontally provided reaction solution passage.

The present invention discloses an X-ray tube comprising a vacuum envelope comprising a first tubular part having an X-ray exit window in an opening on a leading end side and an attachment flange on a base end side, and a second tubular part communicating with the inside of the first tubular part and projecting from a peripheral part of the first tubular part; and an electron gun and a target both contained in the vacuum envelope. The electron gun emits an electron beam to the target, the target generates an X-ray in response, and thus generated X-ray is taken out through the X-ray exit window. An exhaust pipe for evacuating the vacuum envelope projects from the peripheral face of the first tubular part. The exhaust pipe is disposed inside a virtual surface covering the periphery of the first tubular part and bridging a periphery of a leading end portion of the first tubular part and a periphery of the attachment flange.
