Title: Method and instrument for measuring hardness
Inventor: OHASHI SEIICHI
IPC: G01N27/80
Filed: 1985-09-19
Abstract: PURPOSE:To efficiently measure the hardness of a magnetic material member without exerting external force at all to the magnetic material member or destructing said member by obtaining the current value at which the residual magnetism of the magnetic material member changing in conformity with the hardness of the magnetic material member to be measured is made zero. CONSTITUTION:A primary coil 10A for generating a magnetic field and a secondary coil 10B for detecting a magnetic flux are wound as a yoke 8 of a magnetic sensor as a magnetic path forming part having a U-shaped section. The magnetic material member 2 to be measured is pressed to such sensor 4 to form a closed magnetic circuit. A coil sensor driving means 6 is connected to the sensor 4. Electric current for excitation is passed from a primary circuit 6A of the means 6 to the coil 10A to magnetize the member 2 to the satd. region. The demagnetization current in the reverse direction is then passed from a secondary circuit 6B to the coil 10A so that the residual magnetism of the member 2 is made zero. The current value at which the residual magnetism changing in conformity with the hardness of the member 2 is made zero is displayed on an ammeter 24 as a means for displaying the current value. The hardness of the member 2 is thus efficiently measured.

IPC: H01F27/10
Filed: 1983-11-09
Abstract: PURPOSE:To reduce a flow rate getting over ribbs of a refrigerant, and to prevent a partial temperature rise by bringing the rib and the rib formed to both surfaces of a cooling panel into contact or close. CONSTITUTION:Ribs 10 formed to both surfaces of a cooling panel are brought into contact or close and fixed, and the periphery of the panel is welded. One parts of the ribs can also be spot-welded at that time. Since the flow B of a refrigerant getting over the ribs 10 changes the direction of its flow among the ribs and the ribs and flows along the surfaces of the ribs in narrow clearances among the ribs, the flow path of the flow getting over the ribs increases and pressure loss augments, and the flow rate of the flow B of the refrigerant can be reduced.
