A lens barrel standard position detection device, attached to a lens barrel equipped with a fixed tube having a first member and a movable tube rotationally moving back and forth along an optical axis of the lens barrel and having a second member engaging the first member of the fixed tube, to detect when the movable tube reaches a predetermined standard position. The lens barrel standard position detection device includes an actuating element movable between a first position and a second position, the actuating element moving to the second position when a working plane portion of the second member moves into contact with the actuating element corresponding to the movable tube reaching the predetermined standard position along the optical axis, an urging member which maintains the actuating element in the first position in a normal state due to an urging force of the urging member, and a detection unit which detects when the actuating element moves to the second position which opposes the urging force of the urging member, thereby detecting the movable tube reaching the predetermined standard position.

A simulation rider transporting apparatus includes a seat having means for constraining an attitude of a rider mounted on a first base and having a second base positioned under the first base. Elevation means for elevating the first base include two cranks which are arranged opposite to each other between the first and the second base. Each of the cranks has crank arms with each crank arm having one end coupled to the second base. A crank rod is provided for coupling the other end of each crank arm to the first base. Drive means are provided for changing a relative angle between the two crank arms to a predetermined value and for holding the changed relative angle.

When defective pixels of a solid state image pickup device of a video camera are corrected by signal processes, a white spot noise is detected by closing an iris and by comparing the signal level and a level of only a dark current. Further, in this case, a gain of an AGC circuit for controlling a gain of a video signal is raised and a precise detection is executed. By executing such a detecting operation at the time of turn-on or turn-off of a power source, the user is not annoying. In the ordinary photographing, a reference level in detection of a white spot noise is set to an optimum value in accordance with a temperature of the solid state image pickup device or its peripheral temperature or the gain of the AGC circuit so that the white spot noise detection is not influenced by the temperature of the solid state image pickup device or the operating state of the AGC circuit.

A semiconductor integrated circuit has a memory which can enter active state or standby state, and the memory has voltage generation circuits for bit lines and source lines with which memory cells are connected. The voltage generation circuits make the potential of the bit lines and the potential of the source lines equal to each other in response to an instruction to transition from active state to standby state. The voltage generation circuits produce a potential difference between the bit lines and the source lines in response to an instruction to transition from standby state to active state. In standby state, the potential of the bit lines and that of the source lines are equal to each other. Therefore, sub-threshold leakage does not occur between the source and drain of each memory cell. In active state, the source line potential is not varied.
