Patent number: 8416040Abstract: In a joystick device, a rotation position detector for detecting a rotation position of a rotatable cylinder having one end coupled with a dial knob is provided between the cylinder and a case. The detector includes a drive gear provided around the cylinder, a rotary body which has a driven gear provided around its outer periphery and is in mesh with the drive gear, multiple magnets provided on the rotary body, and a magnetic sensor provided in the case to face one end portion of the rotary body to detect the rotation position of the cylinder based on positional change relative to the magnets along with rotation of the rotary body. Such arrangement enhances the degree of design freedom for arranging a magnetic sensor in the axial direction of the cylinder in detecting a rotation position of the cylinder by the sensor and reduces a necessary number of magnets.Type: GrantFiled: April 10, 2012Date of Patent: April 9, 2013Assignee: Toyo Denso Co., Ltd.Inventors: Takanori Terao, Satoru Nakagawa

Publication number: 20120260760Abstract: In a joystick device where a tilting operation direction of an operation shaft is detected based on positional change of a magnet relative to a magnetic sensor, the magnet being moved with tilting of the operation shaft, a slider is arranged between a base facing a board fixed to a case and a magnet holder to which the operation shaft is swingably coupled; the magnet holder is joined to the slider such that the slider guides relative movement of the holder in a first linear direction orthogonal to the axis of the operation shaft but prevents relative movement of the holder in a second linear direction orthogonal to the first direction; and a guide mechanism configured to guide movement of the slider in the second direction is provided between the slider and the base. This prevents variation in the detection accuracy regardless of tilting of the shaft.Type: ApplicationFiled: April 10, 2012Publication date: October 18, 2012Applicant: TOYO DENSO CO., LTD.Inventors: Takanori TERAO, Satoru NAKAGAWA, Hideaki ITO

Process for producing polyester, polyester produced using said process, and polyester molded product
Patent number: 7868126Abstract: This invention provides a polyester and a polyester molded product, which, while maintaining color tone, transparency, and thermal stability, can realize a high polycondensation rate, are less likely to cause the production of polycondensation catalyst-derived undesired materials, and can simultaneously meet both quality and cost effectiveness requirements, which can exhibit the characteristic features, for example, in the fields of ultrafine fibers, high transparent films for optical use, or ultrahigh transparent molded products. These advantages can be realized by using, in the production of a polyester in the presence of an aluminum compound-containing polyester polycondensation catalyst, an aluminum compound having an absorbance of not more than 0.0132 as measured in the form of an aqueous aluminum compound solution, prepared by dissolving the aluminum compound in pure water to give a concentration of 2.Type: GrantFiled: June 24, 2005Date of Patent: January 11, 2011Assignee: Toyo Boseki Kabushiki KaishaInventors: Katsuhiko Kageyama, Tooru Kitagawa, Kenichi Funaki, Masaki Fuchikami, Kazuo Katayose, Takahiro Nakajima, Toshiyuki Tsuchiya, Satoru Nakagawa, Fumikazu Yoshida, Haruhiko Kohyama, Naoki Watanabe -

Patent number: 6828717Abstract: The present invention provides an electron gun which includes an electrically non-conductive substrate through which a perforation is provided. The electron gun is characterized in that a cathode-structure supporting member is welded to power-feeding members that are bonded to a stem side of the electrically non-conductive substrate, the cathode-structure supporting member supplying power to a heater included in a cathode structure. Structured as such, it becomes possible to reduce the size of the electron gun in the tube-axis direction, since an additional member for supporting the heater becomes unnecessary. In addition, the cathode-structure supporting member makes the electrically non-conductive substrate to work as a wiring board for supplying voltage to the cathode, thereby realizing a slim cathode-ray tube. Further, the above structure improves accuracy in the assembly process of the electron gun, thereby improving the yield factor.Type: GrantFiled: October 22, 2002Date of Patent: December 7, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoji Yamamoto, Satoru Nakagawa, Mika Yamagishi

Patent number: 6705913Abstract: An impregnated cathode whose initial electron emitting performance, lifetime property, and insulating property for an electron gun are excellent and that is suitable for mass production, and a method for manufacturing the same. In the impregnated cathode, the porosity of the sintered body of porous metal is continuously increased as the distance in the depth direction from an electron emitting face is increased. A pellet of sintered body of metal raw material has pores in it. The pores are filled with electron emitting material. The porosity is continuously increased as the distance in the depth direction from an electron emitting face is increased. Thus, since the discontinuity inside the pellet is not formed, a reaction generating free Ba continuously and smoothly proceeds on the entire pellet. In addition, since raw material powder having more than one kind of particle size is not necessary to be used, the manufacturing process can be simplified. Moreover, various functions such as lifetime property, etc.Type: GrantFiled: January 25, 2001Date of Patent: March 16, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Satoru Nakagawa

Patent number: 6565402Abstract: A cathode structure comprises a cylindrical metal sleeve having aperture portions at both ends, a base metal having an aperture portion on one end, which is fitted onto one of the aperture portions of the metal sleeve, and an electron-emitting layer, which is formed on a flat portion of an outside surface of the base metal. After an electron-emitting material is sprayed onto the base metal, its surface is mechanically flattened to form the electron-emitting layer. Thus, the planarity of the surface of the electron-emitting layer can be improved without deterioration of the electron emission characteristics and the moiré can be decreased without reduction of the resolution.Type: GrantFiled: September 10, 2001Date of Patent: May 20, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahide Yamauchi, Satoru Nakagawa, Yoshikazu Iwai
