Patent JP-H03148583-A (JP)
Title: Refrigerator
Inventor: KAJIMARU KOUHEI
IPC: F25D25/00
Filed: 1989-10-31
Abstract: PURPOSE:To prevent the overcooling of the rear wall of an auxiliary vessel by a method wherein a heat insulating section, regulating the direct contact of cold air, supplied from the rear upper part of a vegetable chamber, with the rear wall, is provided so as to cover the rear wall of the auxiliary vessel. CONSTITUTION:One part of cold air, flowing along the rear surface wall of a chilled chamber 3, flows along the upper surface of a lid member 15 as shown by an arrow sign B in a diagram while the balance of the same flows into a cold air passage 12 along the rear surface wall of a vegetable chamber 4 through a guide duct 17 as shown by an arrow sign A. A vegetable vessel 11 is cooled by the cold air which flows as shown by the arrow signs A, B. When the cold air, which flows as shown by the arrow sign B, passes through a moisture permeable body 16, excessive moisture in the vegetable vessel 11 is deprived whereby the humidity of the inside of the vegetable vessel 11 is regulated so as to obtain a condition suitable for the preservation of the vegetables in the vessel 11. On the other hand, the cold air, which flows as shown by the arrow sign A, deprives heat from the vegetable vessel 11 while advancing through the cold air passage 12 and, therefore, the temperature of the air is gradually increased, however, the low-temperature cold air will never be contacted directly with an auxiliary vessel 14 since a heat insulating member 18 covers the rear surface wall 14a of the auxiliary vessel 14.

IPC: H01F1/22
Filed: 1990-10-26
Abstract: PURPOSE:To realize a yoke core whose density is high and whose coercive force can be set to an arbitray value by using the following: an Fe powder; and an Fe-Si alloy powder which contains Si in a specific amount. CONSTITUTION:A yoke core is formed as follows: an Pe-Si alloy powder which contains 15 to 40% of Si in terms of its weight % and whose residual part is composed of Fe, an Fe powder and a lubricant are mixed; and a mixed substance which has been mixed in such a way that the content of Si in a sintered body is at 2.5 to 7% is molded and sintered. Its density is at 7.4 to 7.7g/cm<3>. When the sintered body is annealed, its coercive force is adjusted to a prescribed value; it is annealed at a temperature of 1100 to 1300 deg.C for 1 to 24 hours. Thereby, Si is solid-dissolved in Fe as the main component of fine crystal particles; the magnetostriction and the magnetic anisotropy are reduced effectively. When the annealing operation is executed at the temperature of 1100 to 1300 deg.C for 1 to 24 hours, the crystal particle size of the sintered body for the yoke core can be adjusted to an arbitrary value. The coercive force Hc of the yoke core can be set arbitrarily within a range of 0.1 to 0.9 Oe.
