Patent JP-S54149002-A (JP)
Title: Gear pump
Inventor: TERUYAMA HIDEO
IPC: F04C2/18
Filed: 1978-05-13
Abstract: PURPOSE: To prevent errosion due to cavitation by raising the pressure in the tooth space nearly to the ejection pressure prior to the opening of the speed slot in the tooth space.  
     CONSTITUTION: Oil pressure drawn into suction port 19 by the rotation of gears 12 and 13 is discharge from discharge port 18, but low oil pressure drawn from suction port 19 enters the low pressure area via inlet 21. On the other hand, high pressure oil on the side of discharge port 18 enters the high pressure area and at the same time it adjusts, via speed slot 17, the pressure distributions between the side surfaces of gears 12 and 13 and bush 14. Further, small diameter hole 23 is formed on bush 14, and its other end is connected to the accumulator chamber. Consequently, the tooth space containing low oil pressure is maintained nearly at the same pressure as that on the side of discharge port 18 by the oil pressure of the accumulator chamber; and as a result, the pressure inside the tooth space is gradually raised.

Filed: 1989-03-10
Abstract: PURPOSE:To sufficiently exhibit the cooling function of a cooler by lowering the heat resistance between the cooler and the cold stage in a vacuum vessel. CONSTITUTION:The heat transmission body consists of 1st, 2nd copper sheets 31, 32 which respectively have the same polygonal conical shape, a spring 33 which is provided between the same, and plural multi-layered thin-film copper sheets 34, both ends of which are respectively touched and fixed to the polygonal conical faces, facing each other, of the 1st, 2nd copper sheets 31, 32. The 1st, 2nd copper sheets 31, 32 have respectively the polygonal conical shape and the ends of the multi-layered thin-film copper sheets 34 are respectively touched and fixed thereto and, therefore, the contact areas are as shown by diagonal lines 27a to 27d if the polygonal conical shape is a pyramidal shape. The contact area of the sheets 34 is large so the heat resistance value of the heat transmission body is, therefore, lowered. Since the ends are in contact with approximately the front faces of the polygonal conical faces of the 1st copper sheet 32, the heat is eventually dispersed and the contact heat resistance which determines the heat resistance value of the single heat transmission body is lowered.
