Title: Heating method of heat-shrinkable tube for reinforcing optical fiber
Inventor: MATSUMOTO MICHITO
IPC: G02B6/24
Filed: 1982-12-16
Abstract: PURPOSE:To prevent the sticking between a heater and a heat-shrinkable tube after cooling and to facilitate their separation by winding a nonadhesive sheet around the surface of the heater which heats the heat-shrinkable tube of the melt-sticking connection part of the optical fiber. CONSTITUTION:The heat-shrinkable tube 3 made of polyethylene for reinforcement of the melt-sticking connection part of an optical fiber core 2 contacts the top surface of the heater 1, but the sheet 4 of a 0.1mm. thickness nickel silver sheet whose one surface is coated with ''Teflon'' to a 30mum thickness is wound around the heater surface. This method which utilizes the nonadhesiveness of this ''Teflon'' coat requires only an about 80g force for separation after cooling as compared with an about 500g force in a coventional method, and the sticking force is almost eliminated when the heater temperature is held at 60 deg.C, obtaining great effect on operativity and reliability.

IPC: G01K7/24
Filed: 1982-12-20
Abstract: PURPOSE:To simplify structure and to realize long-time continuous monitoring by disposing the primary coil of a rotation side and the secondary coil of a standstill side opposite to each other, and detecting variation in the impedance of the secondary coil. CONSTITUTION:A rotating body 8 to be monitored is equipped with a temperature switch 9 and the primary coil 10 as the rotation-side coil. When the rotating body 8 rotates, the primary coil 10 faces the secondary coil 11 radially and periodically once a turn with a gap between. When the temperature at the monitor part rises and approximates dangerous temperature, the temperature switch 9 operates to enter an opening/closure state opposite to that in a normal state. Therefore, the impedance of the secondary coil 11 changes. Consequently, the unbalanced voltage of an AC bridge circuit rises and is amplified by an amplifier 16 and then applied to a processing circuit 17. Then, an alarm signal is generated to put an alarm 18 in operation.

Title: Device for controlling feedwater for waste heat recovery boiler
Inventor: SHIGENAKA TOSHINORI
IPC: F22D1/12
Filed: 1989-08-31
Abstract: PURPOSE:To enable satisfactorily controlling the feedwater to a high-pressure drum by means of a high-pressure feedwater pump of small capacity by throttling the flow in quantity of the feedwater to a drum by means of a flow- regulating valve to an extent not causing trouble to the control of the flow in quantity of the feedwater to the high-pressure system in the part beginning with a high-pressure economizer. CONSTITUTION:When the differential pressure at a feedwater-regulating valve 17 is larger than a prescribed valve, a signal '6' is transmitted by a transmitter 33 relating to the feedwater temperature at the inlet to a low-pressure economizer. For the signal '6', for example, approx. 60T/H may be set as a quantity of recirculation not exceeding the specified point of a high-pressure feedwater pump 15. When the differential pressure at the feedwater-regulating valve 17 has fallen below a prescribed point, a signal 'a' is transmitted by the transmitter 33 relating to the feedwater temperature at the inlet to a low-pressure economizer. For the signal 'a', approx. 40T/H may be set. The quantity of recirculation is thus throttled from 60T/H to 40T/H so that differential pressure can be ensured across the feedwater-regulating valve 17.

Abstract: PROBLEM TO BE SOLVED: To obtain a toy that can generate the electrical power, without the use of a battery by generating an electrical power through conversion of kinetic energy accumulated in a rotating body into an electrical power, and then outputting this electrical power. SOLUTION: When a rotating force is given to a fly-wheel 12, electricity is generated because a magnet 5 comes close to or is separated from a coil 6 at a high speed. While the rotation is continued, based on the characteristic of fly-wheel 2, electricity is generated continuously.

Here, magnets are symmetrically allocated through a plurality of equal intervals with good balance as the electrical power generating means, and moreover coils are also allocated with a plurality of equal interval as the power generating means, and the conversion efficiency is improved. As a result, necessary power can be supplied, depending on the power consumption of output means and application purpose. As an output means, optical output, sound output and operation output can be used.
