Title: Dust cleaner with multi-stage expansion arm
Inventor: MIKI KIYOTSUGU
IPC: E02B5/08
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent the length of an expansion arm from being expended by providing a slide shoe on an inner surface of the bottom of a fixed arm, a guide roller in front of the upper end of a lower stage arm and a slide shoe on the rear surface. SOLUTION: A telescopic expansion arm comprising a fixed arm 4, an intermediate arm 5 and a lower stage arm 6 is provided on a dust cleaner 1. A rake 7 is provided on the lower stage arm 6. The rake 7 is laid out on the upstream side of a bar screen slantingly provided on a water current. A slide shoe 2 is provided on the inner surface of the lower part of the fixed arm 4 while a guide roller 26 is provided in front of the lower end of the lower stage arm 6 and a slide shoe 28 is provided on the rear surface. When dust and dirt are caught with the bar screen and scraped up with the rake 7 by extending the expansion arm, a maximum pressure during the extension of the arm is received with a guide roller 26. Even if a large reaction force is inflicted, it is turned into a rolling friction, thereby minimizing the resistant value and minimizing the spacing of a guide support member.  It is, therefore, possible to shorten the length of the arm.

Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by leaving a power supply mode of a link layer controller to be reset even when a CPU power supply mode is set so as to inactive the link layer controller when connection to other node by a physical layer controller is not available. SOLUTION: A power supply mode for a CPU 15 is set and reset of a power supply mode of a physical layer controller 13 is released.

Title: Method for operating liquid-circulation cell
Inventor: KAMITSUMA ICHIRO
IPC: H01M50/77
Filed: 1985-10-31
Abstract: PURPOSE:To enable charge and discharge to be performed without an external power source and a commericial power source needed, by intermittently circulating electrolytic solution by using electrical energy stored in a secondary cell during a charge-and-discharge term of constant current control. CONSTITUTION:When a charging is performed in a static state of a pump, zinc ions and bromine ions existing in electrolytic solution inside a cell gradually decrease because of no electrolytic solution circulating inside a cell-reaction chamber, and electrical resistance of the electrolytic solution increases from a charging region of constant current-controlled charge-and-discharge, together with a rise of the charging voltage. With a change in this process, the charging voltage rises, and when the voltage becomes in excess of a setting base directly prior to its rapid rise, the pump is operated by electrical energy stored in the cell to circulate the electrolytic solution existing in the tank for successive charging. This intermittent operation of the pump is available also at the discharging term.

Abstract: PURPOSE:To always keep the best talking quality by providing a filter limiting the band of at least either an output of envelope or a demodulation output to each branch and selecting a branch according to a level of the output of the filter. CONSTITUTION:In case of the occurrence of interleave adjacent channel interference, interleave adjacent channel interference detectors 23,28 switch changeover switches 25, 30 to the position of (b) and a beat by the interleave adjacent channel is eliminated in the envelope output of a diversity branch.
