  • Publication number: 20210323380
    Abstract: An object of the present invention is to provide a vehicle air conditioning device that can solve the decrease of a circulation refrigerant quantity while effectively using the heat of a temperature control object in heating a cabin. The heating operation of a vehicle air conditioning device (1) includes an external air heat absorption heating mode for heating a cabin in a manner that a refrigerant discharged from a compressor (2) radiates heat in a radiator (4), the refrigerant is decompressed, and then the refrigerant absorbs heat in an outdoor heat exchanger (7), and a temperature control object heat absorption heating mode for heating the cabin in a manner that the refrigerant absorbs heat in a refrigerant-heat medium heat exchanger (64), and these modes are performed while being switched. The heating operation is started in the external air heat absorption heating mode.

  • Publication number: 20210324961
    Abstract: Enlarged holes are formed at respective end portions of a valve hole housing a spool by forming an upper recessed groove and a lower recessed groove at each end portion. The respective lower recessed grooves are in communication with discharge ports. The spool includes discharge lands and discharge packing portions, which open and close discharge passages connecting an output port and the discharge ports. When the discharge land and the discharge packing portion open the discharge passage by displacing of the spool, the discharge passage and the discharge port are in communication with each other through the enlarged hole by positioning the discharge land and the discharge packing portion inside the enlarged hole.

  • Patent number: 9528031
    Abstract: Slurry composition and a method of substrate polishing used in chemical mechanical polishing (CMP). The present invention concerns a slurry composition containing a polishing agent and a water soluble polymer. The slurry composition contains a water soluble polymer that has a solubility parameter in the range of 9.0 to 14.0 and that may contain hetero atoms at a level sufficient to lower the polishing rate near the edges of the polished substrate defined as the region within 1 mm of the outer edge of the polished substrate to a level below the mean polishing rate of the polished substrate. The water soluble polymer may have a mean molecular weight in the range of 200 to about 3,000,000, and the mean molecular weight may be in the range of 200 to 110,000 if hetero atoms are present in the main-chain structure and the SP value is under 9.5.

  • Patent number: 9500589
    Abstract: Disclosed is a sample holding carrier allowing samples to be measured accurately, and a fluorescence detection device for use with the sample holding carrier. A biosensor substrate includes a base substrate, a plurality of wells formed on a first surface side of the base substrate; and grooves formed on the first surface side of the base substrate separately from the wells and generating fluorescence under exposure to excitation light. The fluorescence detection device applies excitation light to the grooves, thereby figuring out the level of the fluorescence to be detected from the biosensor substrate. As a result, the fluorescence detection device can amplify the detection signals of the fluorescence generated when the excitation light is applied to the wells to an appropriate level, thereby accurately detecting the fluorescence generated in the samples.
