摘要： Process for producing a copper plated resin article by forming a uniform copper coating having excellent adhesive strength on a fiber-reinforced or unreinforced thermoplastic or thermosetting resin article having a heat deformation temperature higher than 165.degree. C. The resin article is heated along with a source of copper formate under a reduced pressure or in a non-oxidative atmosphere to a temperature in the range above 165.degree. C. but lower than the heat deformation temperature of the resin article. The process makes it possible to produce a resin article having formed thereon a copper layer having an excellent adhesive strength by a very simple manner, and the resin article thus obtained can be used in various industrial fields.

摘要： The invention relates to a sintered silicon nitride-silicon carbide composite material excellent in toughness and strength and to a process for producing the same. The present sintered composite material is substantially formed of silicon nitride predominantly in .beta.-phase and about 5 to 35% by weight of silicon carbide predominantly in .beta.-phase, which is characterized by the microstructure such that the silicon nitride is in the form of fine grains comprising elongated grains, 0.2 to 1.0 .mu.m in length of minor axis and 1 to 10 .mu.m in length of major axis, and equiaxed grains, 1 .mu.m or below in average size, and the silicon carbide is in the form of equiaxed grains, 1 .mu.m or below in average size, said silicon carbide grains being uniformly dispersed. Having a three-point flexural strength of at least 95 kg/mm.sup.2 and a fracture toughness (K.sub.IC) of at least 54 MN/m.sup.3/2, the present sintered material is excellent in toughness and strength. The process for producing such a material is disclosed in detail.

摘要： A master device transmits a beacon signal including information related to a proximity wireless communication area in a predetermined cycle by using a transmission power which allows the beacon signal to reach beyond the proximity wireless communication area. When a slave device receives the beacon signal from the master device, the slave device estimates a distance to the master device in accordance with the information of the beacon signal. When a wireless communication terminal is located within the proximity wireless communication area, the slave device is connected to the master device by using a proximity wireless communication.

摘要： In this signal detection device (100), a delaying unit (101) delays a first distributed signal or a second distributed signal distributed from a received signal for a period of time of T1 to form a first multiplication signal, and delays the one for a period of time of T2 (T2>T1) to form a second multiplication signal. An integrator (104) calculates a first correlation value by integrating the result of multiplying the first distributed signal and the first multiplication signal. An integrator (105) calculates a second correlation value by integrating the result of multiplying the second distributed signal and the second multiplication signal. An evaluation unit (108) evaluates whether the signal to be detected, which is a periodic signal with a period of T1 or a periodic signal with a period of T2, exists or not, on the basis of the first correlation value and the second correlation value.

摘要： A conventional packet frame includes a MAC header, one MAC service data unit (MSDU) and a frame FCS. This frame is repeated to send a plurality of MSDUs. A proposed packet frame includes a MAC header, a plurality of MSDUs and a frame FCS. A unique bit pattern is provided in the MAC header to distinguish the proposed packet frame from the conventional packet frame. Thus, the total data stream can be shortened.
