Title: Coated optical fiber
Inventor: SHIRASAKA ARIO
IPC: G02B6/44
Filed: 1983-07-05
Abstract: PURPOSE:To prevent longitudinal crack and to obtain a high transmission characteristic by providing a resin layer between a buffer layer provided on the outside circumference of an optical fiber and a reinforcing coat layer formed on the outside thereof and adhering the resin layer and the reinforcing coat layer. CONSTITUTION:A resin layer 4 is interposed between a buffer layer 3 provided on the outside circumference of an optical fiber 1 and a reinforcing resin (FRP) layer 5 consisting of fiber-reinforced plastics. The resin layer 4 and the FRP layer 5 are adhered. The resin layer 4 is preferably formed of a curable resin. The resin layer 4 of the optical fiber having such constitution supports the FRP layer 5 and suppresses the deformation of the FRP layer 5 and therefore the mechanical characteristic of the fiber is improved and the incidence of generating longitudinal crack is decreased. The microbend occuring in the FRP layer 5 is prevented by such resin layer 4 and therefore the high transmission characteristic of the coated optical fiber is assured and the fiber is used for a core for an underground buried communication cable, etc.

On the other hand, a governor 14 controls a guide vane according to the rotational speed deviation and generating output set value of said hydraulic turbine 8. A sequence controller 21 adds a speed correction value to be increased to a speed set value and computes the optimum flow rate and real flow rate of water for the hydraulic turbine on the basis of the real number of revolutions of said turbine and the opening quantity of said guide vane. When the difference between said optimum flow rate and real flow rate is more than a permissible value, the correction value is added to the operating output set value.

IPC: G03B17/00
Filed: 1989-05-16
Abstract: PURPOSE:To reduce the unnecessary power consumption of a sensor which detects the vibration of the camera by stopping power supply to the sensor when the camera is mounted on a tripod. CONSTITUTION:This camera is equipped with the sensor 1 which detects the vibration of the camera, a power feeding means 2 which supplies electric power to the sensor 1 from a battery power source E, a tripod mounting detecting means 3 which detects the camera being mounted on the tripod, and a power supply control means 4 which stops the power supply to the sensor 1 by the power feeding means 2 when the camera is mounted on the tripod. Therefore, when the tripod mounting detecting means 3 detects the camera being mounted on the tripod, shake detection is not necessary, so the power supply to the sensor 1 by the power feeding means 2 is stopped under the control of the power feeding control means 4. Consequently, when the camera is mounted on the tripod, the power is not fed to the sensor 1, so the power consumption is reduced.

Title: Induction heat emitting roller
Inventor: HAYASHI SHOJI
IPC: G03G15/20
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To make flat the heat emitting distribution in the longitudinal direction of a roller without dropping the heat emitting efficiency by forming the peripheral wall of the roller from electric conduction parts and non-conduction parts which are arranged alternately in the axial direction of the roller, and positioning the conduction parts so that they mate with a plurality of induction coils. SOLUTION: In an induction heat emitting roller to work using electromagnetic induction, the body of fixing roller 1 is arranged so that electric conduction parts 3 and non-conduction parts 2 are installed alternately in the axial direction of the roller. Therein an eddy current flows only in the conduction parts 3, and not in the non-conduction parts 2. The eddy current generated in each conduction part 3 mating with respective coil 5 makes an inhibited interference with its adjacent conduction part 3, and the heat emission efficiency in these conduction parts 3 is enhanced. Otherwise, the peripheral wall of the roller is configured with an electric conduction part composed of thick portions and thin portions which are arranged alternately in the axial direction of the roller, and the thick portions are located as mating with a plurality of induction coils. Accordingly the heat emission amount is increased in the part corresponding to a barrier between the coils, and the temp. distribution in the longitudinal direction of the roller is flattened.
