In order to reliably form a coating layer on the interior surface of a primary lining such as an underground pipe, etc., in a short time and form a coating layer having a uniform thickness, a spray gun 62 is attached to a revolving ring 30 attached to a running truck 2, right and left drive wheels of the running truck 2 are respectively independently driven and controlled to moving the running truck 2 in a primary lining 90 while the revolving ring 30 is rotated at a steady peripheral velocity to blow out a coating material from the spray gun 62, whereby a homogenous coating layer is formed with a fixed thickness on the interior surface of the primary lining 90.

An integrated cellular and cordless communication system in which cellular calls are forwarded to a landline telephone number associated with a personal base station when a subscriber terminal is determined to be within a predefined vicinity of the personal base station is described herein. Once forwarded to the personal base station via external network elements, such calls may be answered using a cordless device operative to communicate with the personal base station. Alternately, the calls may be transferred to a voice messaging module within the personal base station. When the subscriber terminal is determined to have been removed from within the vicinity of the personal base station, a message from the personal base station to the external network elements results in modification of a call forwarding address such that subsequent calls intended for the subscriber terminal are in fact routed thereto. The personal base station may also be optionally implemented to enable the forwarding of calls intended for the personal base station to the subscriber terminal. A subscriber could indicate the desire for this type of call forwarding by way of, for example, a user interface of the personal base station. In response, the personal base station would issue a request to the external network elements to forward subsequent calls intended for the landline telephone number of the personal base station to the subscriber terminal.
摘要:
Aluminum carbonate hydroxide ammonium, a new compound, is produced by causing a solution of ammonium hydrogencarbonate to be reacted upon by a soluble aluminum salt. .alpha.-Alumina is obtained by thermal decomposition of this ammonium aluminum carbonate hydroxide. By sintering said .alpha.-alumina, there is obtained sintered .alpha.-alumina.

A communication system is provided whereby desired information can be transmitted in accordance with conditions and the application. The communication system includes a PHS terminal and a provider system that is capable of information communication with this terminal. The PHS terminal has a voice recognition section that receives voice from a microphone and recognises the received voice signal, an input device that selects the output form of the voice signal, a conversion section that converts the recognised voice signal with the selected output form, and a transceiver that transmits the converted voice signal to the provider equipment; the converted voice signal is further transferred from the provider system to another destination wireless communication terminal device. This output form includes for example “dialect”, “intonation/imitated voice of a celebrity etc.” or “modulation”. Conversion filters convert the voice signal in accordance with these.
摘要:
A data collection system in which, in communications between each of terminal units and a data collector through a power line, the data collector subjects a polling signal generated by a polling generating circuit to spread spectrum modulation by a spreading section, and superimposes the spread signal on the power line, while each of the terminal units subjects the incoming spread signal thereto superimposed on the power line to de-spread spectrum demodulation and recognizes it, and superimposes the data subjected to spread spectrum modulation on the power line after a certain period of time different from that in other terminal unit has passed. The data collector collects the data obtained by subjecting spread signals successively coming thereinto each by being superimposed on the power line to de-spread spectrum demodulation according to the polling.
