Abstract: A substrate processing apparatus A1 includes: cup 1 for storing processing solution 92 to process substrate 91; stage 2 to be raised and lowered along lifting shaft 31 extending in vertical direction z in cup 1; mount 4 provided on stage 2 to mount substrate 91; and pivoting member 5 attached to mount 4 such that pivoting member 5 is pivotable about pivoting shaft 51 provided along circumferential direction ? centered at lifting shaft 31. Pivoting member 5 includes holding portion 52 located inward of pivoting shaft 51 in radial direction r, and abutting portion 53 located outward of pivoting shaft 51 in radial direction r. As stage 2 is lowered, abutting portion 53 abuts against cup 1 to cause pivoting of pivoting member 5, thereby reducing a distance between holding portion 52 and mount 4 with substrate 91 therebetween. These configurations reduce unintended effects in processing substrate 91.

Abstract: Each time a time corresponding to one period of an intermittent reception process in a vehicle-side device elapses, a transmission interval of a notification signal is controlled so that a transmission time of a preamble of the notification signal is shifted in a direction in which the transmission time is relatively delayed from an execution time of the reception process. Further, when the transmission time of the preamble passes through a range of the execution time of the reception process during this relative shift, the transmission interval of the notification signal is controlled so that the entire transmission time of the preamble is included in the range of the execution time of the reception process.

Abstract: An optical reading system including a warning sound for preventing theft of a portable optical reading apparatus (scanner). A timer is activated when movement of the scanner is detected by a movement detection device mounted on the scanner, indicating that the scanner has been lifted (moved) from a stationary condition. A user determination unit determines whether the movement of the scanner is caused by an authorized user. When the user is an authorized person, a timer is reset. When the timer is not reset during a predetermined time period, a warning sound is generated at a sound level which changes from a low sound level to a loud sound level over a period of time unless a predetermined operation is performed. In one embodiment, a second warning sound is generated at a stationary receiving station when the scanner does not respond to a polling signal.
