Abstract:
The public address system 1 comprises a transmission medium (4) including a main transmission path (4-1) and at least one branch transmission path (4-2) branching from the main transmission path (4-1), a plurality of loudspeakers (3) connected to the transmission medium (4), a first branch monitoring device (10a), and a second branch monitoring device (10b). The second branch monitoring device (10b) only transmits a transmission signal (S-2) from the main transmission path (4-1) into the branch transmission path (4-2) when the second branch monitoring device (10b) has detected that there is no transmission of the transmission signal (S-1) from the branch transmission path (4-2) to the second branch monitoring device (10b).
Abstract:
The public address system (1) comprises a transmission medium (4) configured to transmit a communication signal, a plurality of loudspeakers (3), and a plurality of communication controllers (10) arranged in parallel on the transmission medium (4) so as to correspond to the loudspeakers (3) respectively. Each of the communication controllers (10) includes a first filter unit (11) configured to prevent passage of the communication signal, a receiver (15a) arranged so as to receive the communication signal before the first filter unit (11), a controlling unit (13) configured to determine whether to transfer the communication signal received by the receiver (15a) onto the transmission medium (4), and a transmitter (16b) configured to transfer the communication signal received by the controlling unit (13) onto the transmission medium (4) according to the determination by the controlling unit (13).
Abstract:
The fuel pump driving structure includes a camshaft (3, 103) and a pump cam member (6, 106). The camshaft (3, 103) is arranged to be rotatably supported at one end by a cylinder head (1). The pump cam member (6, 106) has a fitting hole (6a, 107b) into which the one end of the camshaft (3, 103) is press fitted, and arranged to be operatively coupled to a high-pressure fuel pump (5). The pump cam member (6, 106) includes a pump cam section (8, 108) and a first contact section (6b, 107c). The pump cam section (8, 108) has a first lift portion (8a, 108a) arranged to operate the high-pressure fuel pump (5), and a base circular portion (8b, 108b) that does not operate the high-pressure fuel pump (5). The first contact section (6b, 107c) is arranged in a position offset from a position of the first lift portion (8a, 108a) with respect to a circumferential direction and contacting a portion of the camshaft (3, 103) in an axial direction at a position radially outward of an external circumferential surface of the one end of the camshaft (3, 103).
Abstract:
Disclosed is a heat-expandable/peelable acrylic pressure-sensitive adhesive tape or sheet which includes at least a pressure-sensitive adhesive layer containing a blowing agent, a peelable or peel-assisting film layer comprising an oriented poly(ethylene terephthalate), and a viscoelastic substrate containing microparticles, in which at least the peelable or peel-assisting film layer and the microparticle-containing viscoelastic substrate constitute a multilayer structure, and the multilayer structure is arranged on or above at least one side of the pressure-sensitive adhesive layer so that the blowing agent-containing pressure-sensitive adhesive layer is in contact with the peelable or peel-assisting film layer with or without the interposition of another layer.
Abstract:
In a scooter vehicle, a front frame (12) extends obliquely downward and rearward from a head pipe (11). Rear frames (13, 14) extend rearward from a bottom part of the front frame (12). A seat (5) is disposed on upper parts of the rear frames (13, 14). A footboard (25) is disposed in front of the seat (5) while positioned lower than the seat (5). A fuel tank is disposed underneath the footboard (25) and stores fuel. A leg shield (24) extends upv/ard from a front part of the footboard (25) and covers the rear of the front frame (12). A fuel filler part (51) has a fuel filler opening for supplying fuel to the fuel tank, and is disposed in the leg shield (24). The fuel filler opening is disposed to the side of the front frame (12) and above an under bracket (16). The fuel filler opening is also disposed below a connection part between the head pipe (11) and the front frame (12).

Abstract:
An object of the present invention is to shorten the time required by processing, and to simplify the work and increase the number of samples processed, in the X ray analysis of a specific substance contained in a sample. To achieve the object, a method for assaying the content of a specific substance in a sample 106, comprises a measurement step (S3) of irradiating the sample 106 with X rays, and measuring the spectrum of the sample 106, and an assay step (S4) of comparing the components of the specific substance in the spectrum of the sample 106 and in a reference spectrum that has been pre-stored for the sample 106, and determining whether the specific substance is contained in the sample 106 in an amount equal to or greater than a specific value.
