Then, for example, to the outer peripheral surface of the shaft 11 and the end face of the outer annular body 12 are fixedly secured slit disks respectively whic are opposed to photoelectric converters. The torsional angle theta is determined by measuring the phase difference between both outputs of the converters to detect the torque.

Title: Information service system using mobile communication terminal equipment
Inventor: HONDA TOSHIYUKI
IPC: H04W4/02
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To provide the information service system that serves area information without increasing the communication amount of a channel and uses a mobile communication terminal equipment facilitating maintenance and operation. SOLUTION: A base station CS and a mobile communication terminal equipment PS provided to the information service system are available of 2-way radio communication. In the case of acquiring area information by the terminal equipment PS, the terminal equipment PS makes a call to a predetermined telephone number (S3). In this case, the base station CS with a strongest radio wave strength is selected and a telephone number is sent to the base station CS. The base station CS receiving the telephone number retrieves and reads the area information from an area information database of its own station in response to the reception of the telephone number (S6) and sends the area information to the terminal equipment PS sending the telephone number (S7).  Since the base station CS has the area information database, the service of the area information is attained by only communication between the terminal equipment PS and the base station CS.

Title: Method for treating decontaminated waste liquid
Inventor: KAKIMOTO AKIRA
IPC: G21F9/12
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to decrease the necessary number of costly shielded drums by removing fully ions of radioactive elements from a decontaminated waste liquid. SOLUTION: The treatment device is constituted of a waste liquid tank 3, a waste liquid supplying pump 4, an Li-type positive ion exchange resin column 1 and two mixed-resin column 2 filled with a mixed resin made of an H-type positive ion exchange resin and an OH-type negative ion exchange resin. After a decontaminated waste liquid containing ions of radioactive elements is passed first through the resin column 1 to remove the ions of the radioactive elements together with other bivalent and trivalent positive ions from the waste liquid and then through the mixed-resin column 2 to remove organic acid by absorbing it, the cleaned liquid is sent to an existing waste liquid treatment device and is treated there.  Consequently, the quantity of a treated waste liquid in a process for removing the ions of the radioactive elements increases sharply in comparison with a mixed resin, which makes it possible to reduce the necessary number of costly shielded containers filled with ion exchange resins.

Title: Injection of powder
Inventor: KOJIMA TERUAKI
IPC: C22B9/10
Filed: 1981-11-05
Abstract: PURPOSE:To prevent the condition that the supply of a powdery body such as a desilicating or dephosphorizing agent can not be performed due to the reflux of molten pig iron or steel into the nozzle of a lance resulting in clogging the nozzle with the powdery body, when the powdery body is injected into the molten pig iron or the like, by thrusting pressurized gas in the lance through its upper part. CONSTITUTION:A desilicating or dephosphorizing agent A in a lift tank 1 is fed through a carrying pipe 2 into a lance 3 by gaseous pressure and injected through the nozzle 31 of the lance into molten pig iron or the like inside a ladle 4 to perform prerefining such as desilicating or dephosphorizing. Hence, a pressing nozzle 5 is inserted into the upper part of the lance 3 to inject pressing gas for raising the pressure of spraying the powdery body through the nozzle 31 of the lance. As a result, the reflux or invasion of the molten pig iron into the lance 3 is prevented so that the clogging of the lance 3 with the invasion of the molten pig iron which would make the injection of the powdery body impossible or damage the lance 3 in a short time can be inhibited. On this occassion pressure inside the carrying pipe 2 is detected by a sensor 6, the detected value is amplified by an amplifier 61, and the opening rate of a pressure- regulating valve 51 for the pressing nozzle 5 is properly controlled so as to protect the molten pig iron from being cooled by injecting an excess amount of pressing gas through the pressing nozzle 5.
