Title: Manufacture of alloy magnet
Inventor: IBATA AKIHIKO
IPC: C22F1/00
Filed: 1985-02-14
Abstract: PURPOSE:To obtain a magnet showing a high magnetic characteristic when inner-peripheral magnetization is applied thereto by a method wherein a hollow cylindrical billet made of a polycrystalline Mn-Al-C alloy magnet made anisotropic beforehand is subjected to compression machining in the direction of the axis thereof so that the inner peripheral surface of the billet is formed to be indented. CONSTITUTION:A hollow cylindrical billet formed of a polycrystalline Mn-Al-C alloy magnet made anisotropic beforehand is subjected to compression machining in the direction of the axis thereof at a temperature of 530 to 830 deg.C, and thereby the inner peripheral surface of the hollow billet is formed to be indented. The compression machining is not always needed to be successive, but may be divided into a plurality of processes. In the state after the compression machining, in comparison with the state before the machining, the inside diameter of the hollow cylindrical billet 1 is contracted with the advance of the compression machining, and part of the inner peripheral surface thereof turns to be in contact with a protuberant portion of a punch 3. With the further advance of the compression machining, the inner peripheral surface of the billet 1 is formed substantially in the shape of the external surface of the punch 3. The compression machining may be ended at an appropriate time point after part of the inner peripheral surface of the billet 1 turns to be in contact with the punch 3.

IPC: A61B5/08
Filed: 1989-02-03
Abstract: PURPOSE: To measure correctly by means of a sensor by arranging a solid state sensor within a sensing chamber which is formed in a duct via a passage for an extracted gas and which is connected to a second chamber. CONSTITUTION: A manifold 23 is connected to a solid state sensor assembly 21 and a pressure sensor 22. A gas sensor assembly 21 generates an electric output signal indicating a concentration of alcohol vapor in a breathing passing through the manifold 23. A module 17 is programmed to read out the electric output signal from the gas sensor only when the pressure sensor 22 indicates that a specified minimum pressure is kept within the manifold 23. A sensor chamber 46 is positioned near a second chamber 102 to reflect promptly any variation in the concentration of alcohol within the sensor chamber 46, since a passage 106 for an extracted gas is small in capacity. Thus, the electric output signal generated by the sensor element 61 can follow the alcohol concentration of the breathing in the second chamber 102 correctly.

Title: Surface microscope and surface microscopic method
Inventor: HOSAKA SUMIO
IPC: G01N37/00
Filed: 1990-02-07
Abstract: PURPOSE:To set the minute force that acts between a probe which is provided at the tip of a cantilever and a sample readily and highly accurately with respect to an interatomic microscope, a surface-interface microscope, a magnetic- force microscope and a scanning-type tunnel microscope. CONSTITUTION:When an STM probe 3 enters into a tunnel region, a tunnel current flows between the probe 3 and a cantilever 2. The tunnel current value is compared with a specified value in a constant-current servo circuit 9, and a Z1 signal 10 for a probe scanner 5 is outputted. The position of the probe 3 in the direction of the Z axis is controlled so that the tunnel current becomes the constant value. Then, a specified amount of a driving signal 10' is sent into a Z-axis piezoelectric element in the scanner 5 so as to set minute force at a specified value. The probe 3 is moved away by a specified distance DELTAZ in the direction of the Z axis. Then, a sample 1 is brought close to the lever 2, and a probe 6 at the tip of the lever 2 is pushed with the sample 1 until the tunnel current flows again. When the tunnel current flows again, the Z-axis piezoelectric element of a sample scanner 4 is driven with a Z2 signal 11 from a constant-current servo circuit 13. The position of the sample 1 in the direction of the Z axis is controlled so as to keep the tunnel current constant.
