Abstract: A lock system that unlocks a lock with an unlock signal, prevents malfunction of locking or unlocking, and reduces power consumption of a receiving unit side that receives the unlock signal. The lock system avoids radio wave interference of the unlock signal and prevents malfunction of locking or unlocking by providing irregularity in a transmission timing of the unlock signal to a device that unlocks a lock with the unlock signal. In regard to a reception of the unlock signal, the lock system sets a receiving window by setting a reception-ON time and a reception-OFF time, and by stopping an operation of the receiving unit except during the reception-ON time, reduction of power consumption can be achieved.

Abstract: A power usage method is provided for using power supplied from a first device at a second device. The power usage method includes causing the second device to perform an initialization process to obtain a value of a current used when consuming the power at a voltage that is a minimum prerequisite for the second device to perform a predetermined process; and causing the second device to execute the predetermined process while consuming the power in a manner that the current does not exceed the obtained value.

Abstract: A communication mediation apparatus for mediating communication between an information processing device and a communication network includes a first communication unit, second communication unit, a determining unit, and a setting unit. The first communication unit communicates with the information processing device by first communication speed. The second communication unit communicates with the communication network having multiple second communication speeds. The determining unit determines the second communication speed being closest to the first communication speed from among the multiple second communication speeds. The setting unit sets the determined communication speed to the second communication unit.

Abstract: A device connected to a bus and a device driver for controlling the device, capable of preventing the device from falling into a forced use suspension (disable) state. Prior to notice of power consumption by a USB device connected to the bus(USB), the device driver acquires knowledge of remaining electric power that can be supplied by the bus. According to whether the remaining electric power is satisfactory for power consumption expected to be notified of by the USB device, the device driver permits the notice of power consumption by the USB device and causes the bus to start electric power supply, or executes avoidance processing in order to avoid shortage of power.

Abstract: There is disclosed a microfilm search device which detects a frame or between-frames dimension from a density change in the running direction of a microfilm to determine the presence of frames and search for a desired frame. The detected density change is binarized to determine the dimension of the frame or between-frames. When detecting the length of a portion where the binarized signal representing film transparent portion continues, the dimension is corrected short. When detecting the length of a portion where the binarized signal representing film non-transparent portion continues, the dimension is corrected long. The frame or between-frames dimension can be detected with high accuracy to enhance the frame searching accuracy. Moreover, pulse signals outputted from an encoder are counted by a counter to monitor the film feeding amount, and the counter is reset when frames are detected and when the film feeding direction is reversed.

A ring oscillator circuit of another aspect includes a plurality of logic gates connected in cascade in a ring form and a plurality of signal lines whose wiring layout is made using wiring layers of a multi-layer structure and which are disposed between adjacent ones of the plurality of logic gates, and one of the signal lines is disposed spirally in such a manner as to be close to itself at portions thereof in at least two of the wiring layers of a multi-layer structure. When such a layout of the signal lines is employed, the difference between the frequency of the pulses actually output and the frequency of the output pulses based on simulation can be reduced to minimum.

Abstract: A photographic film separation method. A spool has a slit, a first rod-shaped member and a second rod-shaped member. The second rod-shaped member has a lower rigidity than that of the first rod-shaped member so that the second rod-shaped member is flexibly deformable. The first rod-shaped member has an engagement member which engages one longitudinal direction end portion of a photographic film. The second rod-shaped member has a presser pawl which maintains engagement between the photographic film and the engagement member. The separating member has a higher rigidity than that of the second rod-shaped member, and has a tip end portion which penetrates substantially simultaneously to positions at which the engagement member and the presser pawl are provided. The separating member is inserted between the engagement member and the photographic film positioned inside the slit, and releases the engagement between the photographic film and the engagement member.
