摘要:
To keep communication even if a distance between transmission devices is farther and a transmission distance therebetween is longer.A transmission device for alternately performing transmission and reception to/from a communication destination transmission device transmits transmit data to the communication destination transmission device. It receives return data transmitted by the communication destination transmission device after the transmit data reaches the communication destination transmission device. A predetermined period of time is assumed as one time unit, one transmission of transmit data and one reception of return data are tried within the one time unit, and when it is determined that one transmission of transmit data and one reception of return data do not fall within the one time unit, the transmission device is controlled such that N number of transmit data are continuously transmitted and then N number of return data are continuously received within N (N is an integer of two or more) time units.

A fitting structure for a connector housing can maintain a stable vibration absorbing function. A flange (14) of a connector housing (10) is provided on the periphery with an outer annular retaining wall (15). A rubber sheet (20) is contained in an interior of the connector housing (10). The connector housing (10) is attached to a body (E) of an engine by means of bolts (B) and nuts (N). When fattening bolts (B) and nuts (N), the rubber sheet (20) is compressed. In a conventional fitting structure, the compressed rubber sheet (20) expands laterally to bulge out of the flange (14). Since the outer annular retaining wall (15), however, serves to limit the lateral expansion of the rubber sheet (20) so that the rubber sheet (20) does not bulge out from the flange (14), it is possible to prevent the rubber sheet (20) from changing its physical and/or chemical nature and to effectively maintain its vibration absorbing function.
摘要:
A tube-shaped film, made of fluorine resin, has a fold-free, smooth, and uniform inner peripheral surface formed thereon by a surface treatment. An apparatus for treating the inner peripheral surface of the tube-shaped film includes a holding device for holding the tube-shaped film on the inner peripheral surface of a cylindrical body with a cylindrical configuration of the tube-shaped film maintained. A treatment device is inserted into the cylindrical body to treat the inner peripheral surface of the tube-shaped film held on the inner peripheral surface of the cylindrical body. The holding device and the treatment device make a uniform linear motion relative to each other and a uniform rotary motion relative to each other.
摘要:
A method for surface modification of a fluorine resin by irradiating the surface of the fluorine resin containing a heat-resistant light-absorbing polymeric material and/or a light-absorbing material is with laser light. Surface properties of the fluorine resin molded articles, particularly adhesion and wetting properties, can be greatly improved by a simple operation with high efficiency.
摘要:
The present invention relates to a process for modifying the surfaces of the molded materials made of fluorine resins comprising irradiating an ultraviolet laser beam on said surfaces in the presence of an ultraviolet-absorbing compound and a fluorosurfactant. According to the process, the adhesive and wetting properties and the like of the surfaces of the molded materials made of fluorine resins can be remarkably improved.
