Title: Method and apparatus for cleaning pipe with fluid circulating
Inventor: PIEERU MAROWA
IPC: F28G3/10
Filed: 1989-11-09
Abstract: PURPOSE: To eliminate the need for removing a bundle of water tubes periodically for cleaning by separating the protruding corner, i.e., the ridge, on the polygonal cross-section of a movable element farthest from the across-sectional axis of a tube during rotation of the movable element thereby preventing deposition of scale in the heat exchanging tube. CONSTITUTION: A member 1 constitutes the bearing for a journal 5 and a movable element 11 which can thereby be turned freely with the stress of fluid circulating through a tube 10. The coil-like movable element 11 arranged on the tube 10 is made of a thin metal band having rectangular cross-section and at least one ridge 13 thereof abuts continuously on the inner side face of the tube 10 for continuous cleaning thereof. The movable element 11 is rotary driven easily by fluid circulating through the tube 10 because of its flat shape and since the ridge 13 is farthest from the axis of the tube 10, i.e., closest to the inner surface thereof, it is rotary driven while abutting on the inner surface regularly to ensure cleaning through scraping action thereof and turbulent action of fluid.

Title: Air-conditioner
Inventor: NAKAJIMA MASAKAZU
IPC: F24F13/20
Filed: 1992-10-06
Abstract: PURPOSE:To reduce noise generated by vibration by a method wherein a rear plate of a blower is overlapped to a rear surface of a casing and fixed to it. CONSTITUTION:As an electrical motor 33 for a blower 7 is driven, air is sucked from a suction port 37 of the blower 7 through a suction panel and air is blown from an air blowing port 35 in an upward direction. Air blown from the blower 7 passes through a heat exchanger and heat exchanged air is blown from a blowing port of a blowing panel. Although vibration of the electrical motor 33, a vane wheel 31 or blown air during an operation of the blower 7 are apt to be transmitted to a rear surface 6 of a casing 3, the rear surface 6 is reinforced to restrict the vibration due to the fact that the rear plate 34 of a fan case 29 is overlapped on the rear surface 6 so as to make a substantial double structure. Accordingly, noise caused by the driving operation of the blower 7 is reduced.

Title: Tab tape for manufacture of semiconductor device
Inventor: MORITA TOSHIO
IPC: H01L21/60
Filed: 1987-11-20
Abstract: PURPOSE:To prevent the width of an external connection lead part of a metal lead layer from being reduced upon establishing the device in a multi-pin configuration by keeping a standard tape width, by forming the metal lead layer with a metal film having at least two layers insulated each on a substrate insulating layer. CONSTITUTION:Metal layers 1 are provided respectively on the face and back of a substrate insulating layer 5, internal connection lead parts 3 of which are protruded into an opening part 6 so as to intersect each other. Although a stepped part is formed between the adjacent internal connection lead parts 3 in this situation, a particular problem is not produced upon bonding because strong force is exerted to the internal connection lead part when it is connected to a semiconductor device. Connection with external apparatus and measurement of electrical characteristics after the connection of the semiconductor device are performed across a tape vertically differing from a case in a conventional TAB tape. Thus, the areas occupied by the external connection lead part 2 and a measuring pad part 4 with respect to the total area can be reduced by about 1/2 compared with the conventional TAB tape.
