Title: Thermal head and manufacture thereof
Inventor: OTA MASATOSHI
IPC: B41J2/335
Filed: 1991-06-19
Abstract: PURPOSE:To improve the printing characteristics in a tilted surface type thermal head, and make the manufacture easier. CONSTITUTION:A tilted surface 6 which is tilted to a major surface 4 is formed at the end part of an insulating substrate 2, and heating elements 8 are arranged at the leading end side on the tilted surface 6. A selective electrode 12 and a common electrode 14 for the heating element 8 are extended from the tilted surface 6 to the major surface 4, and are connected to a semiconductor integrated circuit device for driving 16 on the major surface 4.

Patent JP-H0464910-A (JP)
Title: Perpendicular magnetic recording head
Inventor: NAITO TATSUYA
IPC: G11B5/127
Filed: 1990-07-03
Abstract: PURPOSE:To reduce the magnetization shift width to improve the recording density by suppressing recording demagnetization due to a following block generated for inversion of a recording current of a head. CONSTITUTION:Since a magnetic body of a following block 1b has a step (d) in this ring head, a head magnetic field Hy of the following block 1b is quickly reduced according as going away from a gap 1c. When a medium is moved in a prescribed direction and is magnetized, it is magnetized in the same manner as a conventional head. However, the medium hardly receives a magnetic field in the opposite direction just after inversion of the recording current in a part distant from the gap because it receives the magnetic field Hy in the medium magnetized state just after insertion of the recording current. Thus, recording demagnetization due to the head magnetic field is suppressed.

Filed: 1990-07-03
Abstract: PURPOSE:To prevent ink flow paths from interfering with each other to improve an image quality by a method wherein a piezoelectric element is divided into an active part which is displaced in thickness to press a flow path and an inactive part which does not press the flow path, and the range of the active part is specified.

Filed: 1983-09-27
Abstract: PURPOSE:To improve the dissipation of the white mist by providing outside air inlets along the circumferential wall of a casing and in the tangential direction relative to a ventilating duct, and disposing a cooling section in such inlets. CONSTITUTION:The outside air is drawn by a fan in a ventilating duct 5 from inlets 7 to wet cooling sections 8, and is further directed into a cooling water tower 4. While passing through the wet cooling sections 8, a direct contact heat exchange takes place with the hot water to be treated to cool down same. In this manner, the resulting damp air moves in a spiral flow on account of the inlets 7 that are directed in the tangential direction relative to the ventilating duct 5, and the joining and mixing with the outside air (a) from respective inlets 7 are enhanced. Therefore, the thermal condition in the ventilating air flow is equalized, and the ventilating, lifting air flow is so stabilized that it lifts higher up to improve the dissipation of the white mist.
