摘要： A high frequency bar type heater can be inserted into a hole of an object to be heated even if there is an obstruction above the hole. The high frequency bar type heater has a flexible and slender heat resisting and insulating tube (2) having both its ends closed so as to form a water-tight container. A flexible and slender conductor coil (3) is inserted in the heat resisting and insulating tube (2). A magnetic core (5), sectioned in plural pieces in its longitudinal direction, is contained on an inner side of the conductor coil (3). A flexible cooling water pipe (6) is inserted in the heat resisting and insulating tube (2) so as to cool the interior thereof. The high frequency bar type heater thus has flexibility as a whole. The magnetic core may also be formed of a flexible material.

摘要： A high frequency heating method of a bolt sets a maximum achievable temperature Tmax in an inner surface of the bolt with hole to a value which is not higher than a final heat treated temperature To. A maximum thermal stress .sigma.max occurring in the bolt with hole is set to a value which is not more than a yield stress .sigma.ys of the bolt material. From the maximum thermal stress .sigma.max, a temperature difference .DELTA.T is obtained between Tmax and a mean temperature Tmean along an entire cross section of the bolt, under the condition that .DELTA.T is to be not more than a permissible maximum temperature difference .DELTA.To obtainable from the yield stress of the material. The maximum suppliable power by Tmax, .DELTA.T and dimensions of the bolt are obtained, and then a heater is inserted into a small diameter hole of the bolt with hole and the maximum suppliable power, which value is obtained by the above operation, is supplied to the heater so that the bolt with hole is heated to be elongated. The temperature of the bolt with hole, while it is being heated, is not higher than To, and hence lowering of the material strength can be prevented. The thermal stress is not higher than .sigma.ys, hence the life consumption due to fatigue can be suppressed and loosening of the bolt with hole within a short time becomes possible.

摘要： An information transmission method using arc and apparatus thereof are applied to a loudspeaker and the like having the function of illumination. The information transmission method is characterized in that arc current supplied to an arc generating device is modulated by a signal based on information to vibrate arc column so that at least one of audible waves, ultrasonic waves and arc light is employed to transmit the information. Arc having small mechanical inertia is employed as a sound producing device and accordingly can be used as a loudspeaker having a good frequency characteristic and large output. It can be used as a sound producing device having the function of illumination by utilizing strong light emitted from arc column.

摘要： A high frequency bolt heater is provided which can heat up the inside of a narrow hole much faster than a conventional bolt heater employing a resistance wire. The high frequency bolt heater includes an induction heating coil made of a copper tube bent in a hairpin fashion and whose shape is made approximately circular in section by pinching a magnet between opposed portions thereof. The heater can be inserted into a hole bored in the axial direction of a metallic bolt. A length of the coil is made approximately equal with that of the bored hole, and the magnet is omitted from a region of the heater which corresponds to a screw portion of the bolt for mounting a nut. An adjustable stopper made of a heat resistant electrical insulator is provided for setting a necessary length of the induction heating coil to be inserted into the hole, and a heat resistant insulator is provided on the surface of the induction heating coil.
