摘要:
The invention provides an indoor LAN system, including: a distributor for distributing or delivering a television signal having a frequency band contained in a first frequency band, and a LAN signal having a frequency band contained in a second frequency band to a plurality of common antenna terminals provided in a plurality of rooms through house wirings, respectively; a television•LAN signal-separating apparatus for receiving as its inputs the television signal and the LAN signal through corresponding one of the plurality of common antenna terminals provided in the plurality of rooms, respectively, and outputting the television signal and the LAN signal to a television signal-outputting portion and a LAN signal-outputting portion, respectively, through signal separation; and a display device for processing at least one of the television signal and the LAN signal separated from each other in the television•LAN signal-separating apparatus.
摘要:
An electrical connection box has upper and lower casings (10, 11) for accommodating circuitry. A surrounding wall (10a) of the upper casing (10) fits inside a surrounding wall (11a) of the lower casing (11). Engaging locking claws (10b, 11b) project from the outer surface of the surrounding wall (10a) of the upper casing (10) and from the inner surface of the surrounding wall (11a) of the lower casing (11). An upper wall of the upper casing (10) is inclined down from a center portion to three peripheral edges. A drainage path (13) is defined by a clearance between the surrounding walls (10a, 11a) of the upper and lower casings (10, 11). A bottom wall of the lower casing (11) has drainage holes (14) at the bottom end of the drainage path (13).

Upper and lower casings (10, 11) have the surrounding walls coupled together. A bolt (B) is mounted beforehand in the casings (10, 11), and projects through a bolt hole (11c) in the lower casing (11) to fix the casings (10, 11) to a holder (20). A first bush (15) is fixed in the lower casing (11) and a second bush (16) is interlocked with an outer circumferential surface of the first bush (15). The bolt (B) passes through the bushes (15, 16) so that a lower surface of the bolt head (Ba) engages the upper end surface of the first bush (15). On the other hand, an inward-projection is formed on an upper part of the second bush (16), and contacts the upper surface of the bolt head (Ba). Thus, the bolt head (Ba) is held rotatably between the upper end surface of the first bush (15) and the inward-projection.
摘要:
A molecular weight of a polymer is measured by a process including steps of: heating a polymer portion with a heating device, measuring, with a temperature measuring device, the difference between temperatures of at least two points of the polymer portion at each of which the polymer portion is subjected to a thermally different influence from each other by the heating device, and estimating the molecular weight of the polymer which corresponds to the difference between the temperatures obtained by the measuring step according to a relationship between the temperature difference and the molecular weight of the polymer which relationship has been beforehand obtained.

The invention provides a process of producing a nozzle member for sucking and transporting a string of yarn having an inner diameter which varies along an axial direction of the nozzle member. The process comprises the step of drawing a pipe stock having a predetermined outside profile so as to transfer the outside profile in an axial symmetrical relationship to an inside profile of the pipe stock. By the process, a nozzle member can be produced readily with a high degree of accuracy.
摘要:
An auxiliary nozzle for a loom, such as an air jet loom within a shuttleless loom, jets pressurized gas in order to prevent stall of weft inserted into warp shedding. At least a tip portion of an auxiliary nozzle body is formed of ceramics material having a very small integrally-molded surface roughness of 0.5 .mu.m or less and having characteristics of high toughness and high strength whereby occurrence of flaws in warp can be minimized and woven fabric of high quality can be obtained. Particularly, by employment of particular zirconia-type ceramics, the moldability, processing properties for drilling and wear resistance can be improved.
