摘要： The automatic gain control method with little being influenced of the unnecessary electric wave, even if strong unnecessary electric wave is near the frequency of input signal, is offered by carrying out change of the delay point level. The automatic gain control system with a scale of few circuit, having low noise property and high adjacent disturbance oppression property, is offered. When the IF AGC signal 112 is smaller than delay point level, the output agcerr of the signal level detector 614 is provided to the 1st loop filter 105. Since the IF AGC signal 112 provided to the IF AGC amplifier 608 is value responding to signal level of IF signal, output is fed back to this amplifier, and control of IF gain is performed automatically. On the other hand, when output of the 2nd loop filter 106 is “0”, output rfzero of the 2nd comparator 108 is set to 1, and “0” is provided to the 2nd loop filter 106. When the output of the 2nd loop filter 106 is not “0”, it is set to “0”, fixed value-rfdump is provided to the 2nd loop filter 106, and the output of the 2nd comparator 108 is converged when output of this loop filter became “0.” For this reason, the RFAGC signal 113 provided to the RF AGC amplifier 602 is set to “0”, and gain of the RF AGC amplifier 602 is fixed to maximum value.

摘要： A plate-like member (8) and three lamp sockets (15, 25, 35) are mounted onto a lamp body (2) to form a rear combination lamp (1). The plate-like member (8) is formed by two thermoplastic resin sheets (9a, 9b) having a hot-melt adhesive therebetween, which are adhesively bonded together, while wire-like conductors (W1, W2, W3, G) are sandwiched therebetween. The plate-like member (8) has three holes (10), and notches (11) are formed in a peripheral edge of each hole (10). Predetermined portions of the conductors (W1, W2, W3, G), which are held between the sheets (9a, 9b), are exposed at the notches (11), respectively. Each of the lamp sockets (15, 25, 35) includes a socket body (16, 26, 36) for receiving connection terminals, and a flange (17, 27, 37). A conductor contact portion of each of the connection terminals projects from the associated flange (17, 27, 37), and is abutted against the associated conductor (W1, W2, W3, G).

摘要： In a real-image finder, an objective optical system forms a real image and a reflecting member has a surface that reflects light from the objective optical system. A transmissive prism that transmits light from the reflecting member has an incident surface on which a light beam from the reflecting member is nearly perpendicularly incident and an emergent surface at an angle to the incident surface. The light from the transmissive prism is incident on an incident surface of a reflecting prism placed close to the emergent surface of the transmissive prism. A reflecting surface of the reflecting prism reflects light from the reflecting surface so that the light reflected from the reflecting surface is totally reflected by the reflecting prism incident surface. An eyepiece optical system guides the light from the reflecting prism to an observer.

摘要： An information processing apparatus is provided in in a hierarchical structure of at least three hierarchies, and communicates with another information processing apparatus that is present in the immediately above hierarchy in the hierarchical structure to determine whether a version of the software installed on the information processing apparatus matches a version of the software installed on the immediately above information processing apparatus. The information processing apparatus also acquires setup information from the immediately above information processing apparatus upon determining that the software version installed on the information processing apparatus matches that of the software installed in the immediately above information processing apparatus.
