摘要:
An apparatus for detecting faults on the surface of a resist master disc and for measuring the thickness of the resist coating layer includes a single light source for generating a laser beam for inspection of the master disc, a first separator for separating the laser beam into a first laser beam which is used for the detection of faults, and a second laser beam which is used to measure the thickness of the resist coating layer. The second laser beam is further separated into two laser beams one of which is irradiated on the surface of the resist coated master disc at a given angle of incidence. The detection of faults on the surface of the master disc is performed by detecting a level change of the quantity of reflection light of the first laser beam from the resist master disc, and the measurement of the thickness of the resist layer is performed by using a ratio between quantities of two laser beams obtained from the second laser beam one of which is detected after being reflected by the surface of the resist master disc.
摘要:
A flow processing system for processing disc-shaped articles such as discs to be used to produce video or audio disc masters, whereby a plurality of processing units for performing respectively different processing operations are combined into a single system in which each disc is moved only horizontally and in a continuously rotating condition, both during processing and while being moved between the processing units. In addition, the supporting structure of the processing units is implemented such as to produce no disturbances in a horizontally directed dust-excluding flow of air, to ensure maximum prevention of adherence of dust particles to the disc surfaces.

摘要:
Provided is an electronic shelf label terminal, an electronic shelf label system, and a display method which facilitate a check for an installation place with good signal quality. An electronic shelf label terminal (1) is a terminal that displays display information received from a management server (3) via a relay device (2). A wireless communication unit of the electronic shelf label terminal (1) receives radio waves from a plurality of the relay devices (2). A display unit of the electronic shelf label terminal (1) displays information on the relay devices (2) accessible from the electronic shelf label terminal (1) for communication to the management server (3), based on field intensities of the radio waves received by the wireless communication unit.
摘要:
To suppress power consumption when product information is not received from a server apparatus. A transmission section (302) of an electronic shelf label (300-1) transmits a registration request signal to the server apparatus. A transmission interval determining section (308) extends a transmission interval of the registration request signal in a stepwise manner in accordance with a time length of an asynchronous state in which a response signal is not received in response to the registration request signal from the server apparatus. A terminal state request signal generating section (305) generates a terminal state request signal making a request to another electronic shelf label that terminal state information be transmitted, and the transmission section (302) transmits the generated terminal state request signal. After receiving the terminal state request signal, the another electronic shelf label transmits the terminal state information. After receiving the terminal state information, the electronic shelf label (300-1) updates, based on the received terminal state information, the time length of the asynchronous state in which the response signal is not received.
