Title: Portable radio wave equipment
Inventor: SUGURO AKIHIRO
IPC: H01Q21/28
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To easily obtain fevorable communication sensitivity in spite of the elevation angle of a communication satellite viewed from the ground by providing plural circular polarization antennas in a portable radio wave equipment and permitting the main beam radiating directions of the antennas to be different. SOLUTION: A plane antenna means 10 is arranged in the case upper surface part of the portable radio wave equipment 92 and, moreover, a hilical antenna means 14 is arranged above a case upper part side surface. The both antennas 10 and 14 are different in the main beam radiating direction but same in an operation frequency band and their polarized wave directions are same rotation. The two kinds of directional antennas 10 and 14 are combined and arranged in the portable radio wave equipment 92 so that stable communication sensitivity is obtained from high elevation angle till low elevation angle. Since the main beam direction of the helical antenna means 14 faces to low elevation angle, a gain loss by a human head part is prevented by executing holding at a separated position above the portable radio wave equipment 92.

Abstract: PURPOSE:To surely switch a low speed cam and high speed cams for each other through a simple construction, by providing a stopper by which a rocker arms and a valve drive member for high speed cams can be connected to and disconnected from each other only when the base surfaces of the high speed cams are located on the rocker arms, and by using the stopper to restrict the switching of the cams. CONSTITUTION:A low speed cam 13A is provided on a cam shaft 10 for driving intake valves. High speed cams 13B are provided on the cam shaft 10 at both the sides of the low speed cam 13A. When an engine is in a low speed range, no pressure oil is supplied through a passage 27 so that a spring 20 puts a selector 19 into a position shown in the drawing. As a result, a plunger 17a is swung in the large-diameter hole of the selector 19. When the engine is in a high speed range, pressure oil is supplied through a passage 27 so that the small-diameter hole of the selector 19 is fitted with the head of the plunger 17a. At that time, a stopper 24 remains engaged in a groove 23 provided in the selector at the end thereof. Only when the selector 19, which is swung together with a high speed rocker arms 15B, is located at the base surface of the cam 13A or 13B and the rocker arms 15B at an angle of swing stoppage, the stopper 24 is disengaged from the groove 23 so that the selector can be moved.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of radiation noise in a cabinet in which a plurality of printed wiring boards are assembled by arranging a wiring cable connecting a first and a second printed wiring boards in a gap part formed by partitioning the inside of the cabinet. SOLUTION: Two printed wiring boards 2, 3 are built in a cabinet 1 of a rectangular box surrounded by planes. A gap part 1b partitioned by a partitioning plate 1a is formed in a part of the cabinet 1. Both ends of a wiring cable 5 connecting the first and the second printed wiring boards 2, 3 are connected by using connectors 4. The wiring cable 5 penetrates the partitioning plate 1a, and a part of the cable is wired via the inside of the gap part 1b. The dimension of the gap part 1b is set so small that the wiring cable 5 can be wired in the gap part. By wiring the wiring cable 5 via the gap part 1b partitioned by the partitioning plate 1a in the cabinet 1, noise generated by the wiring cable 5 can be prevented by using the grounded cabinet 1. The length of a part of the wiring cable 5 which part does not pass the gap part 1b is shortened.
