Abstract: In order to detect an operating state of equipment, when a plate material reaches a support part, a press machine outputs a start signal to move a press part downward. An input receiver receives input of the start signal. An operating detector detects that the press machine is in an operating state. When the press machine moves the press part upward, and shaping of the plate material ends, the press machine outputs a standby signal. The input receiver receives input of the standby signal. The detector detects that the press machine is in a standby state. When the plate material is again conveyed onto a roller conveyer from the support part, the press machine outputs a stop signal. The input receiver receives input of the stop signal. The detector detects that the press machine is in a stop state.

Abstract: A radio control toy vehicle having a two-wheel vehicle body includes a turnably mounted front fork to which a steering section is operatively connected, a front wheel mounted on the front fork through a front wheel shock absorber, a drive case on which a rear wheel mounted on a rear side of the vehicle body is mounted, a wheelie mechanism for shifting the vehicle body to a running state in which the vehicle body runs using the rear wheel while elevating the front wheel above the ground by temporarily pulling up the front wheel against springs provided on the front fork and then, by releasing the pulling up motion and applying a pushing down force to the front wheel by a restoring force of the springs, and a receiver for receiving a control signal from a transmitter and producing a running control signal.

Abstract: A plurality of sensing arms are provided at intervals on a sensor case so as to project outwardly of the case. A light-projecting element and a photoreceptor element forming a pair are provided in the sensor case so as to correspond to respective ones of the sensing arms. Projected light from the light-projecting element advances along the longitudinal direction of the respective sensing arm and is reflected by a reflecting surface so as to be directed toward the neighboring sensing arm through a sensing area. The projected light is reflected twice by reflecting surfaces on the neighboring sensing arm so as to return to the original sensing arm through the sensing area again. The light is reflected by the reflecting surface of this sensing arm, advances along the longitudinal direction of this sensing arm again and is received by the photoreceptor element.
