Title: Defrosting operating method for heat pump and defrosting device
Inventor: SHOJI YOSHIAKI
IPC: F25B47/02
Filed: 1991-01-19
Abstract: PURPOSE:To perform a defrosting operation while continuing an operation of a defrosting device by a method wherein when refrigerant is supplied and distributed to each of heat transfer pipes of a multi-pipe type heat exchanger acting as an evaporator, some of the pipes are not supplied with any refrigerant and the refrigerant is moved in sequence to other heat transfer pipes as the heat transfer pipes not supplied with the refrigerant are elapsed in time. CONSTITUTION:Refrigerant liquid is distributed through each of refrigerant outlet ports 10 of a distributer 8 to each of heat transfer pipes so as to perform a normal heat pump operation. A port closing plug 12 of the distributer 8 is circumferentially moved as time elapses, thereby a supplying of refrigerant is stopped for several heat transfer pipes only of the evaporator. Accordingly, all the heat transfer pipes are supplied with refrigerant while there is a time band in which the supplying of refrigerant is stopped. In the region where the supplying of refrigerant is stopped, it may not act as an evaporator, so that if an elongation of the stopped time band is properly controlled, the adhered frost is volatiled or melted through a transfer of heat and substance between it and the outside air. With such an arrangement, defrosting can be realized while the heat pump is being operated.

Title: Cermet cutting tool excellent in chipping resistance and its manufacture
Inventor: FUJISAWA TAKASHI
IPC: C22C1/05
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain a cermet cutting tool excellent in chipping resistance by setting the minium value of the distribution of nitrogen concentration within a fixed range from the surface in the case where composition analysis is carried out from the surface of a case face toward its inside. SOLUTION: In the case of carrying out composition analysis from the surface of a case face toward its inward, it is desirable that the minium value of the distribution of nitrogen concentration is within the range of 1-100μm from the surface, and nitrogen concentration on the surface is within the range of 1.1-5.0 times as much as the minimum value. When the minium value of the distribution of nitrogen concentration is in a range less than 1μm from the surface, a deposition phenomenon is not improved, and on the other hand, when it is in a deep part exceeding 100μm, the hardness of the surface is insufficient, and desired abrasion resistance can not be therefore obtained.  It is desirable that the minium value of the distribution of nitrogen concentration is within the range of 10-50μm from the surface, and the nitrogen concentration on the surface is within the range of 1.5-3 times as much as the minium value.

Title: Wien filter
Inventor: SUKENOBU SATORU
IPC: H01J37/05
Filed: 1989-01-31
Abstract: PURPOSE:To achieve a compact design with an improved resolution by placing second electrodes crosswise between a pair of electrodes and allowing the resistance value of the second electrodes to change according to a potential gradient between the pair of electrodes. CONSTITUTION:As a voltage applied to electrodes 5a, 5b is brought into contact with a second electrode 7, a voltage is applied to the ends of a conducting material layer 9 of the second electrode 7. This causes the conducting material layer 9, or the surface of potential of the second electrode 7 to change linearly in a horizontal direction. Thus, when +V potential is applied to the electrode 5a and -V potential to the electrode 5b for mass separation, potential distribution within a wien filter can be made uniform by change in the surface potential of the second electrode 7. This results in the formation of almost parallel equipotential lines between the pair of electrodes, making it possible to obtain a uniform electrostatic field. It is assumed here that the second electrode 7 has its insulating base surface covered with a material whose electric resistance is 10<-5>OMEGAcm to 10<2>OMEGAcm.
