Title: Thermal ink-jet head and manufacture thereof
Inventor: UENISHI KATSUZO
IPC: B41J2/05
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent clogging of an ink liquid channel by keeping a constant interval between a substrate and an orifice plate in an ink trench serving as the ink liquid channel. SOLUTION: An orifice plate 5 is arranged on a silicon substrate 7 through ink barrier walls 3a-3e and an ink seal part barrier wall 3 and an ink trench 6 having depth corresponding to the height of the ink barrier walls 3a-3e is made between the silicon substrate 7 and the orifice plate 5. An orifice 5' is made at a position corresponding to the heating resistor 8 of the orifice plate 5. Posts 2a-2h are arranged in the region between an ink supply path 1 and the ink barrier walls 3a-3e wherein the height of the posts 2a-2h is set equal to that of the ink barrier walls 3a-3e. When these posts 2a-2h are arranged in the region of the ink trench 6 and the orifice plate 5 is supported on the silicon substrate 7, the orifice plate 5 touches the silicon substrate 7 in the ink trench 6 thus preventing the ink trench 6 from being clogged.

Title: Vane pump
Inventor: TATSUMOTO TOSHIYA
IPC: F04C2/344
Filed: 1995-02-13
Abstract: PURPOSE: To secure support length at the maximum protruding time of a vane without enlargement so as to reduce noise by extending a back pressure chamber radially inward going over the position of a pressure lead-in groove so as to communicate the pressure lead-in groove with the back pressure chamber at its radially outside part, and bringing a vane into contact with the bottom part of the back pressure chamber. CONSTITUTION: A back pressure chamber 5 is extended radially inward going over a pressure lead-in groove 6, and the pressure lead-in groove 6 is communicated with the radially outside part 5a of the back pressure chamber 5. A vane 2 is drawn into a slit until the inner end 2a comes in contact with the bottom part 5b of the back pressure chamber 5 when the protruding quantity of the vane 2 is the minimum, but sufficient pressure oil is fed into the wide back pressure chamber 5 from the pressure lead-in groove 6 through the communicating part 5a, so that appropriate back pressure always acts upon the vane 2, and the sliding contact of the vane 2 with the inner peripheral surface 3a is guaranteed. Since the support length A1 of the vane 2 by the slit 1 at the maximum protruding time of the vane 2 is lengthened, the pulsation of the vane 2 is suppressed to reduce noise.

IPC: H04L27/26
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a frequency offset correction device by which a transmission efficiency and a demodulation rate can be enhanced. SOLUTION: Frequency rotating devices (A) 109-(C) 111 change a frequency of a base band signal by respective different change amounts. Fast Fourier transform FFT devices (A) 112-(C) 114 apply FFT processing to the base band signal whose frequency is changed by the frequency rotating devices (A) 109-(C) 111. A quality detector 116 detects the quality of the FFT arithmetic result by the FFT devices (A) 112-(C) 114. A discrimination device 117 discriminates FFT arithmetic results with better quality among those by each FFT device based on the detection result by the quality detector 116. The discrimination device 117 uses a change amount corresponding to the FFT arithmetic result whose quality is discriminated better on the basis of the detection result by the quality detector 116 to calculate a frequency offset.
