IPC: H01B12/04
Filed: 1987-07-22
Abstract: PURPOSE:To enable a ceramic coil to be made simply and easily, by employing a series of processes in which sol of raw ceramic material is prepared, a rod-like core member which is dissipated at firing temperature is dipped into the sol, and the member is then lifted, the member being dried over thereafter, moreover a gel layer is formed on the surface of the core member and the gel layer is wrought into a coil configuration to form a compact. CONSTITUTION:After sol 11 is admitted into a dipping vessel 13, a core member 15 is moved downward to be dipped into the vessel. Next, the core member 15 is lifted upward, with the sol 11 adhering to the surface of the member. Then, a drying coil 17 is caused current to flow therethrough to be heated, thereby the sol 11 which adheres to the surface of the core member 15 is dried over to become gel. A gel layer 19 which has the predetermined thickness is formed on the surface of the core member 15 to make an adherend 21. Next, the adherend 21 is made to be rotated at a fixed rate, while a tool is made to be moved from one end of the adherend toward the other end at a fixed velocity, with the head thereof being touched the gel layer 19. Thereby, the gel layer 19 which is formed on the surface of the core member 15 is so eliminated in a spiral configuration that a compact 23 is wrought into a coil configuration. Next, the compact 23 is heated in the air, thereby the core member 15 is burnt down to leave only the gel layer 19. Hereafter, the gel layer 19 is treated with temporary firing in the air, being fired thereafter to make a ceramic coil 25.

Title: Method and device for treating flat article
Inventor: BARUTAA RAISUTO
IPC: B65H29/00
Filed: 1984-09-03
Abstract: The printed products unwound from a storage coil or wound package in imbricated product formation are conveyed over two belt conveyors against a stop. According to one embodiment the printed products are separated from the imbricated product formation before reaching the end of the first conveyor device formed by the two belt conveyors by an acceleration imposed by the second of the two belt conveyors, i.e. they are singled. According to another embodiment the imbrication of the printed products is inverted before the products reach the end of the first conveyor device. The individual printed products fall downward after impinging the stop and are deposited upon the preceding printed product in an imbricated formation. The imbricated product formation is conveyed away by a belt conveyor of a second conveyor device in a conveying direction opposite to the conveying direction of the first conveyor device. A new imbricated product formation is therefore formed upon the last-mentioned belt conveyor within which the printed products assume the same mutual orientation as they had before being wound up upon the storage coil.

Filed: 1987-07-24
Abstract: PURPOSE:To emphatically observe fine dust on a mirror surface substrate by irradiating the mirror surface substrate with laser light from obliquely upper direction and observing scattered light caused by the dust on the substrate with a microscope. CONSTITUTION:The dust 5 watched through an optical microscope 1 is irradiated with the laser light from a laser light source 2 from the oblique direction. Then, if there is no dust 5 on the mirror surface substrate 3 the strong laser light does not enter in the visual field of the microscope because the laser light from the light source 2 is reflected on the substrate 3. Meanwhile, if there is the dust 5 on the substrate 3, the laser light is scattered and a part of the scattered light enters the visual field of the microscope. Since the laser light has high luminance, the scattered light is emphasized against a dark background by the dust 5, which can be observed.

Title: Heat exchanger for outdoor machine
Inventor: WATANABE MIKIO
IPC: F25B39/02
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To restrict an adhesion speed of frost to a heat exchanger, and delay deterioration of heat exchanger efficiency by disposing the heat exchanger on the upstream side of an air flow with respect to a heat exchanger body, and providing a refrigerant tube so as for it to traverse in a plurality of times a plane located parallely to the heat exchanger body. SOLUTION: A refrigerant flowing into a refrigerant tube 2 heat-exchanger with air just before it flows into a heat exchanger body, and joins with the air at an outlet tube. Air A directed to the refrigerant tube 2 is dehumidified because water contained in the air adheres to the refrigerant tube 2 as frost C upon heat exchanging with the refrigerant flowing through the refrigerant tube 2. Since the dehumidified dry air B is directed to the heat exchanger body, even when the heat exchanger body is of a multi-flow type having a higher heat exchange efficiency, adhesion of frost can be delayed upon heat exchanging with the refrigerant flowing into the heat exchanger body, and further a time interval of defrosting operation can be increased.
