摘要:
A lighting-drive device includes: a lighting-drive circuit configured to drive a lamp for lighting of the lamp; an activation circuit configured to produce an activation voltage to be applied to the lamp in order to start lighting of the lamp; and an activation operation detector configured to be provided with a sensing member for sensing an induced voltage and output an operation state notification signal depending on a state of the induced voltage. The sensing member is provided on a circuit substrate on which the activation circuit is formed in such a manner as to be allowed to sense the induced voltage. The activation current flows in response to the activation voltage produced by the activation circuit. The operation state notification signal indicates whether or not the activation circuit has operated normally. The lighting-drive circuit, the activation circuit and the activation operation detector are integrated into one single component.

Disclosed herein is a signal processing apparatus including a processing block configured to perform a carrier shift amount detection process for detecting a carrier shift amount constituting a carrier error used for demodulating an orthogonal frequency division multiplexing signal known as the OFDM signal; and a correction block configured to correct the OFDM signal in accordance with the carrier shift amount. The OFDM signal includes a first preamble signal including subcarriers, and a second preamble signal including subcarriers of which the spacing is narrower than the spacing of the subcarriers included in the first preamble signal. The second preamble signal includes pilot signals which are known signals located at intervals of a predetermined number of subcarriers. The processing block detects the carrier shift amount using a correlation of the subcarriers included in one such second preamble signal.

The battery pack is provided with an analog front-end that detects battery voltage, and a micro-controller connected to the analog front-end that accepts analog voltage signals from the analog front-end as input. The micro-controller switches voltage signals input from the analog front-end to determine failure of the analog front-end or the micro-controller.

A substrate processing method and apparatus can securely carry out a pre-plating treatment that enables uniform plating in the necessary area of the surface of a substrate. The substrate processing method carries out a cleaning treatment and a catalyst-imparting treatment of a surface of a substrate as pre-plating treatments and then electroless plates a metal film on the catalyst-imparted surface of the substrate. The cleaning treatment is carried out in a wider area of the surface of the substrate than that area to which a catalyst is imparted by the catalyst-imparting treatment.

A substrate holding apparatus can meet the request for a smaller-sized compact apparatus while ensuring a sufficient immersion depth of a substrate in a processing liquid. The substrate holding apparatus includes: a substrate holder for supporting a substrate (W) by bringing a peripheral portion of a surface of the substrate (W) into contact with a first sealing member; and a substrate pressing section for lowering relative to the substrate holder so as to press the substrate (W) held by the substrate holder downward, thereby bringing a first sealing member into pressure contact with the substrate (W). The substrate pressing section is provided with a second ring-shaped sealing member which makes pressure contact with an upper surface of a ring-shaped holding section of the substrate holder, thereby sealing the peripheral region of the substrate pressing section.
