IPC: F16K11/07
Filed: 1981-10-08
Abstract: PURPOSE:To reduce the flowing-through of oil and facilitate inching, by making a valve means for connecting a low pressure passage and an oil tank to each other, of a spool which is operated by the pressure difference between tow passages and has a long groove on the peripheral surface. CONSTITUTION:A low pressure selection valve 15 is provided instead of a conventional shuttle-type check valve. In the valve 15, a single spool 18 extending in pilot chambers 19a, 19b is slidably fitted. An oil hole 22c, which connects the upstream and downstream sides of an oil chamber 16b to each other when the spool 18 is in the neutral position, and another oil hole 22d, which connects the upstream and downstream sides of an oil chamber 16b when the spool is in the neutral position, are opened through the spool. As a result, the flowing- through of oil from a high pressure side to an oil tank 7 in the neutral position is reduced and the valve-open cross-sectional area of a passage for connecting the oil tank 7 and a low pressure side to each other to facilitate suction from the tank can be made large enough.

Filed: 1983-08-31
Abstract: PURPOSE:To perform comfortable heating through reduction in a fluctuation in temperature in an under floor type KOTATSU by means of a heat accumulating material, by a method wherein the heat accumulating material is disposed to the inner peripheral wall of the under floor part. CONSTITUTION:A heat accumulating material containing part 7 is attached to the whole surface of an inner peripheral wall 2, comprising side walls and a bottom wall, of an under floor part 1, and the heat accumulating material containing part 7 is filled with a latent heat type compact heat accumulating material 3 having a high heat accumulating amount such as paraffin. Furhther, a heat insulating material 8 is situated throughout the entire surface of the outer periphery of the heat accumulating material containing part 7. Thus, when the interior is increased in temperature under a condition that an infrared heater 5 is turned ON, the heat is accumulated in the heat accumulating material 3, and when the interior is decreased in temperature in a condition that the infrared heater 5 is turned OFF, the heat is radiated from the heat accumulating material 3, and this enables decreasing of a fluctuation in temperature T.

Abstract: PURPOSE:To obtain enough coercive force with increased exchange coupling force in a recording film comprising a multilayer film of specified elements alternately deposited and a film of rare earth-iron group alloy for exchange coupling, by forming the multilayer film in a manner that the film thickness ratio of the alternately deposited layers makes a gradient. CONSTITUTION:The information recording film on a substrate 1 such as plastics, glass or the like having a rugged pattern of guide grooves consists of films 2 of alternately deposited layers and a rare earth-iron group alloy film 3 comprising Tb24Fe66Co10 continuously deposited on the film 2. The film 2 consists of a Pt layer as a platinum group element 2-2 and a Co layer as an iron group element 2-1. By making the alloy layer couple with the multilayer film, the Kerr rotation angle for 400 nm wavelength is 0.55 deg., which is 1.5 times larger than that for 800 nm wavelength. By forming an exchange coupling of TbFeCo, 4 k0e coercive force can be obtained. By providing these multilayer films in a manner that the film thickness ratio gradually makes a gradient, the higher exchange coupling force can be obtained and the coercive force can be increased. Moreover, by providing a metal film on the recording film, the heat resistance and forms of magnetic domains can be improved.
