Abstract: To make the output voltage of a laser power monitor circuit (12) equal to a predetermined value at a predetermined laser power, adjustment is performed by changing an external variable resistance for output voltage adjustment. To achieve this, adjustment is performed by changing the variable resistance so that the difference between a high level output pulse of the laser power monitor circuit (12) obtained when an LD (11) is turned off and a low level output pulse obtained when the LD (11) is turned on is made equal to a target adjusted voltage. This prevents the offset of the laser power monitor circuit (12) from affecting a monitor output voltage, allowing an optical pickup to perform, for example, recording and reproducing with higher accuracy.

Abstract: When a main television is turned on, a power source A, a power source B, and a power source C operate. When the main television is turned off (stand-by state), the power source A and the power source B operate, if the sub-television is turned on, and only the power source A operates, if the sub-TV is turned off. Therefore, even when the main television is turned off, as long as the sub-television is turned on, a broadcast reception process and a wireless video transmission to the sub-TV are performed. If both the main television and sub-television are turned off, then electric power supplies to circuits for the broadcast reception processes are stopped, and as a result, electric power consumption is saved.

Abstract: A frequency offset correcting unit estimates frequency offsets in a preamble period, corrects digital received signals by the estimated initial frequency and further corrects them by residual frequency signals. A receiving weight vector computing unit computes receiving weight vector signals by using LMS algorithm. Based on the error vectors or receiving weight vector signals derived by LMS algorithm, the frequency offsets contained in corrected received signals are also estimated and are outputted as the residual frequency signals. A multiplier weights the corrected received signals with the receiving weight vector signals. An adder sums up outputs of the multiplier so as to output a synthesized signal.

Abstract: A high pressure discharge lamp can be used in a vehicle lighting device as a light source in place of a halogen lamp, and can be driven with a reduced starting voltage while being miniaturized. A gas is filled in a space between an arc tube and an outer tube of the high pressure discharge lamp, the gas being capable of dielectric barrier discharge, to reduce the starting voltage. A metal conductor is arranged in the space between the arc tube and the outer tube to stabilize the starting voltage and perform other functions. The metal conductor can also serve as a lead line. Accordingly, high voltage portions of the lamp are not exposed outside of the outer tube. This can reduce the entire size of the high pressure discharge lamp such that a housing for a headlight using a halogen lamp can be used for this type of high pressure discharge lamp.

Abstract: The head end surface of an optical fiber (2) and the head end surface of an optical fiber (12) are butted to each other in an alignment member (22) of an adapter (21). In the butting, because one of the members clasping the optical fiber (2) is a plate (4a) that is short, the optical fiber (2) is bent and buckled between the left end of the short plate and the right end of the alignment member. Members clasping the optical fiber (12) are a long plate (14b) and a V-grooved base plate (13), and the optical fiber (12) is therefore horizontally fixed between each of right ends of the long plate and of the V-grooved base plate (13) and the left end of the alignment member. This results that the head end surface of the optical fiber (2) and the head end surface of the optical fiber (12) are in tight contact with each other, achieving excellent optical transmission between both optical fibers.
