Abstract: Provided is a work processing apparatus configured so that limitations on the contents of processing for a work piece or the type of work piece can be reduced and processing for a wider range of processing contents and work piece can be performed. In a work processing apparatus 100, a work table 101 is, through a table displacement mechanism 103, supported on a rotation base 120 to be rotatably driven by a table rotary drive motor 125, and a weight holding tool 110 is supported on the rotation base 120 through a weight displacement mechanism 114. The table displacement mechanism 103 includes a rack-and-pinion mechanism configured to displace the work table 101 in an X-axis direction as viewed in the figure. At the table displacement mechanism 103, a power inputter 108 configured to input drive force from a table displacement mechanism drive apparatus 130 is provided.

Abstract: In a communication system across an in-office PC system (10) and an in-enterprise LAN system (20), in order to perform a transmission of packet data from a DDTE (22) on the LAN side to a M-DTE (14) on the personal station side without a need of a provision of complicated means, when receiving packet data addressed to the M-DTE (14) from the DTE (22), a LAN side control unit (23) transmits a connection request including the incoming packet address to a PBX (11) of the in-office PC system (10), the PBX (11) notifies a PS (13) of the incoming signal for the packet address through a CS(12), and on the other hand, the M-DTE (14) connected to the PS (13) acknowledges the incoming signal through the PS (13) and the CS (12) when the packet address which received this notice corresponds to the M-DTE (14), thereby achieving a connection. After the connection, the control unit (23) transmits packet data to the M-DTE (14).

Abstract: In order for the user to perform a transmission of packet data to a desired communication counterpart on a virtual network across a wireless circuit exchange type network system and a LAN without being bothered by address exchange between an address of a physical network and an address of a virtual network, an exchange (10a) performs an address exchange necessary for establishing a communication channel between the terminal equipments within the system using a conversion table, in a mobile wireless data communication system in which a wireless circuit type network system comprising a wireless mobile station (30a), a wireless connection equipment (20a) and the exchange (10a) is connected to a LAN (40a) through a TA (60a) and a router (50a).

Abstract: An acidic or basic hydrogen peroxide cleaning fluid for cleaning a semiconductor substrate, comprising a phosphonic acid chelating agent and a wetting agent, or comprising a wetting agent alone.

Abstract: A process for purification of hydrogen peroxide is provided which comprises contacting an aqueous hydrogen peroxide solution with a chelate resin. According to the process, it is possible to remove impurities in the aqueous hydrogen peroxide solution in high efficiency, and particularly, it is possible to remove iron, aluminum, etc., which are difficult to remove singly by ion exchange resins, up to extremely low concentrations. Highly pure hydrogen peroxide solutions obtained by this invention can suitably used for washing of silicon wafers.

Abstract: In cleaning a semiconductor substrate with a basic aqueous solution of hydrogen peroxide, it is an object to prevent metal impurities adhering to the substrate surface. A cleaning solution of a semiconductor substrate which comprises a basic aqueous solution of a hydrogen peroxide containing a chelating agent having at least two phosphonic acid groups. Preferred chelating agent is 1,2-propylenediamine tetra(methylene phosphonic acid) in amount of 1 ppb to 1000 ppm, together with 0.1 to 20% by weight of hydrogen peroxide and, optionally, 0.1 to 10% by weight of ammonia. Even if the cleaning solution is contaminated with metal impurities, characteristics of semiconductor elements prepared from a substrate are stabilized since no metal impurities adhere on the substrate surface.

Abstract: In a wide area cordless telephone system, an individual-call signal is generated if an incoming call from the telephone network is an individual call to one of cordless stations of a group and a group-call signal is generated if it is directed to all cordless stations of the group. A group of access units are associated with the cordless station of each group to establish a control channel and speech channels with the cordless stations. The access units respond to the individual-call signal by transmitting a speech channel identifier to one of the cordless stations through the control channel and transmitting a ringing signal through a speech channel specified by the speech-channel identifier. In response to the group-call signal, speech-channel identifiers are successively transmitted from the access units to the cordless stations through the control channel and group ringing signals are respectively sent to the cordless stations through speech channels specified by the speech-channel identifiers.
