摘要:
The invention provides a cellular mobile communication system that efficiently performs high-speed communication with mobile terminals within the cell using a single frequency. The mobile communication system sequentially performs polling communication control to plural terminals within the own cell, based on a control of a base station positioned near the center of the cell. With this arrangement, the terminals within the cell can communicate with each other using a single frequency.

A dishwasher includes a main body being generally of a box shape with an open front, a washer tub being slidably extracted from and retracted into the main body through the open front, the washer tub having an open top, and a covering member for blocking a gap to be opened between the washer tub and the main body when the washer tub is fully extracted from the main body. Therefore, when the washer tub is fully extracted from the main body, a rear end of an inner wall of the washer tub is located in front of a front end of the main body to open the gap and the opened gap is covered by the covering member.

An optical transmission system accomplishes optical transmission over a long distance by combining a multiplexing line terminal with optical amplifiers, linear repeaters, and regenerators with optical amplifiers combined together. The system also accomplishes the optical transmission over a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-toelectric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, and with no use of any optical booster amplifier and optical preamplifier in multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.

A particle control device and a particle control method are capable of controlling the occurrences of particles in a vacuum reactor. The particle control device is used in a vacuum processing apparatus having a vacuum reactor, a gas delivery unit for supplying processing gases to the vacuum reactor, and a sample table for supporting a sample in the vacuum reactor, wherein the apparatus subjects the sample to vacuum processing. The particle control device detects particles floating inside the vacuum reactor; generates apparatus condition data indicating a condition of the vacuum processing apparatus; and determines a component which is high in a particle occurrence probability based on detected particle data and apparatus condition data, thereby enabling display of the component selected as the particle source.

A broadcasting receiving apparatus includes a tuner to receive a broadcasting signal and output a reception signal selected therefrom, a demodulation portion to output a video audio signal by demodulating the reception signal from the tuner, an encryption portion to output an encrypted video audio signal by encrypting the video audio signal, a buffer portion to store one of the video audio signal from the demodulation portion and the encrypted video audio signal from the encryption portion, and a control portion to perform control in such a manner that, when the video audio signal needs to be encrypted in the encryption portion, the video audio signal is transferred in the form of first files each having a first capacity (m [KByte]), encrypted on a file-by-file basis in the encryption portion, and stored into a memory region in the buffer portion successively in units of the first capacity, and when the video audio signal need not be encrypted in the encryption portion, the video audio signal is transferred in the form of plural second files each having a second capacity (n [KByte], (m>n)) smaller than the first capacity on a file-by-file basis, and stored into the memory region in the buffer portion successively in units of the second capacity. It is thus possible to provide a receiving apparatus capable of preventing unauthorized copying of a video audio signal committed by tampering with flag information indicating the need for encryption.

A wiper blade includes a wiper strip, a lever assembly and a cover member. The lever assembly has a connecting arrangement and holding claws. The connecting arrangement is connected to a wiper arm. The holding claws hold the wiper strip. The cover member has a cover opening, which is opened on a wiper strip side thereof. The cover member receives the lever assembly through the cover opening. In an interior space between the cover member and the wiper strip, holder end side openings, each of which is a part of the cover opening, are covered by two connecting arrangement end side cover parts. In this way, in the interior space between the cover member and the wiper strip, spaces, into which fluid intrudes, are reduced.

A lever assembly holds a wiper strip, which directly wipes a wiping surface. The lever assembly includes a plurality of levers, which are connected together in tournament style. An axial length of the lever assembly is shorter than an axial length of the wiper strip. A cover member receives the lever assembly, and opposed ends of the cover member hold the wiper strip. The cover member includes a plurality of cover portions, which are formed separately from one another.
摘要:
When determining the presence of foreign particles in a processing chamber by radiating a laser beam inside a processing chamber and detecting scattered light from foreign particles within the processing chamber, the detection of scattered light is performed using a detecting lens having a wide field angle and deep focal depth. Accordingly, the detection of foreign particles floating in the processing chamber can be performed across a wide range, and with uniform sensitivity, with a detecting optical system having a simple constitution.
