Title: Dc machine with e-type interpole
Inventor: KOUZAI YOSHITOKU
IPC: H02K23/24
Filed: 1979-03-24
Abstract: PURPOSE: To prevent the magnetic saturation of teeth on an armature and to secure a wide range of linearity of rectification magnetic flux by establishing a gap length between a leg section of E-type interpole with an interpole winding at a central pole and an armature with a prescribed relation.  
     CONSTITUTION: Opposing to an armature 1, a central pole 81 with an interpole winding 10 and an E-type interpole with leg sections 82 and 83 are provided. Then a gap between the leg section 83 and the armature 1 is established so that the gap length at a portion near the central pole 81 exceeds the gap length at a portion distant from the central pole 81. By accomplishing the jobs as above-mentioned, the gap length between the tooth A of the armature 1 and the leg section 83 exceeds the gap length between the tooth B and the leg section 82, so the magnetic reluctance of the magnetic path Pa including the tooth A becomes bigger than that of the magnetic path PB including the tooth B, and as a rectification magnetic flux generated by the interpole winding 10 is distributed equally to each tooth A and B of the armature,a magnetic saturation of the tooth A on the armature can be checked.

Title: Rotation sensor
Inventor: TERADA YASUHARU
IPC: G01P3/488
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To obtain a rotation sensor which maintains a sufficient output and which can be miniaturized by installing a magnetic-field formation means which is provided with a facing face which is not parallel to the movement direction of a magnetic member which is moved according to the rotation of an object to be detected. SOLUTION: Protrusion parts 31 are formed of a magnetic member which generates a change in a magnetic field according to the rotation of a shaft 2 as an object to be detected. Many of the protrusion parts are formed on the outer circumference of a rotor 3 attached to the shaft 2, and they are moved together with the rotation of the rotor 3. A magnetic 4 is a magnetic-field formation means which forms a magnetic field in a space near the protrusion parts 31, its magnetic pole 41 is formed so as to face the protrusion parts 31, and it has a facing face 42 which is not parallel to the movement direction of the protrusion parts 31. A magnetoresistance element 5 is arranged in a space between the facing face 42 and the protrusion parts 31, and it outputs a detection signal so as to correspond to a change in the magnetic field in the space.  When the facing face 42 is formed at the magnet 4, the installation space of the magnetoresistance element 5 is ensured, and the magnet 4 can be arranged near the protrusion parts 31. As a result, the space can be utilized effectively, and a revolution sensor can be miniaturized.

Title: Screen size decision circuit
Inventor: MAJIMA ISAO
IPC: H04N3/223
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a screen size decision circuit which does not burden a microcomputer too much. SOLUTION: After the output signals Sc of a comparator circuit 3 are extracted in the ranges of three zones of A, B and C, the signals are supplied as signals Sc to a gain amplifier 7 and the signals are amplified by the different weighings for every zone, the signals are integrated by an integrator 8 and the signals are supplied to an A/D converter 9. In the converter 9, a 3-bit digital signal (XA, XB, XC) is outputted according to the output voltage V j of the integrator 8 and a screen size is decided in a microcanputer 10. Therefore, this circuit is controlled by the microcomputer 10 and the magnifying processing in the vertical direction of a picture tube is performed. Because a size decision is performed only if the digital signal (XA, XB, XC) is read one time after a C zone is detected in the microcomputer 10, the burden of the microcomputer is remarkably reduced as compared with a conventional decision circuit.

Title: Manufacture of alloy as ion source
Inventor: MIYAUCHI EIZO
IPC: H01J37/305
Filed: 1988-02-18
Abstract: PURPOSE:To easily generate a micropattern image, by generating pure ion beams from which isotopes are removed for irradiation of a base metal while controlling composition ratios of an alloy to produce the alloy as an ion source with a decreased amount isotopes. CONSTITUTION:The isotopes included in a desired kind of ions generated in the ion source 21 of an ion implanter are removed by an ion mass separator 23 to produce pure ion beams 28. While the alloy composition ratios, defined by a product of an implantation time of the pure ion beams 28 and its electric- current intensity, are under control, the pure ion beams 28 irradiate a base metal 24 as a target for ionic bombardment, to generate an alloy as an ion source with reduced isotopic contents. Thus, no dual image or unclear pattern may appear even in use of the mass separator 23 with a low resolution, when a pattern is drawn with the ion beams. Micropatterns may thereby be easily formed.

Title: Electrostatic capacity type absolute pressure transmitting device
Inventor: MITAKE MASARU
IPC: G01L9/00
Filed: 1984-02-24
Abstract: PURPOSE:To perform stable measurement at a high temperature state, by arranging a vacuum chamber and an introducing chamber on both sides of a detecting chamber having a movable electrode, and measuring the displacement in pressure sensitive diaphragm due to introduced pressure as the displacement of the movable electrode. CONSTITUTION:When pressures in various processes are introduced in an introducing chamber 13, a pressure sensitive diaphragm 17 compresses a shaft 18 toward a vacuum chamber 12. The amount of movement of the shaft 18 is determined by the balance among the introduced pressure, the elasticity of the constituent spring of a movable electrode 8 and the rigidity of the diaphragm 17. When the shaft 18 is moved, the movable electrode 8 is displaced and the gap between both fixed electrodes 9 and 9 is changed. The changing amount of static electricity is made to be an absolute value through lead wires 11, and the detected signal is transmitted. Thus the stable measurement can be performed without using a sealed liquid such as silicone oil and the like and without the change in permittivity even at high temperature in a vacuum.
