摘要： PURPOSE:To obtain a resistance heater for high frequency electrification capable of welding a resin by the successive electrification without generating trouble by forming a sheet from a conductive resistance forming element and an insulating support and suppressing the electrification properties at least in one direction along the surface of the sheet. CONSTITUTION:A resistance heater 14 is formed by cutting a sheet whose electrification properties are suppressed at least in one direction along the surface of the sheet and the direction suppressed in electrification properties coincides with the longitudinal direction of the resistance heater 14. When an electrode 10 and a metal material 5 are electrified by a high frequency in such a state that the electrode 10 is pressed to a resin 7, the route 11 piercing through the resin 7 within upper surface region covered with the electrode 10 is electrified, the resistor 14 and a resin 6 and flows in the thickness direction of the resistance heater 14 within said region. Therefore, the resistance heater 14 generates heat by electrification and the resins 6, 7 on both sides of the resistance heater 14 can be heated and bonded.

摘要： PROBLEM TO BE SOLVED: To peel off the resin coating on the inner surface of a metal pipe even from a metal pipe having a small diameter to which access is hardly gained by simple operation. SOLUTION: The resin coating 3 formed on the inner surface of a metal pipe is reduced in pressure on its inner surface side by closing both ends of a metal pipe 1 to evacuate the metal pipe and the metal pipe 1 is heated to lower the bonding strength of the resin coating 3 and the suction force applied to the interior of the metal pipe is utilized to peel the resin coating 3 from the inner surface of the metal pipe. The resin coating can be peeled even from a long metal pipe having a small diameter by simple depressurizing and heating operation and the metal pipe and the resin coating can be sorted at a low cost.

摘要： PROBLEM TO BE SOLVED: To improve economy by applying specific vibration to a coating film under the condition that removal treatment liquid for treating or treatment liquid of supplementary treatment before or after treatment is brought into contact with the film, thereby shortening a treating time. SOLUTION: Materials 4a to be treated obtained by cutting coating film in chip state are hydraulically transported together with treatment liquid 2 to a trough-like or tubular water channel 1. The materials 4a are conveyed in a wide thin layer state and applied by a vibration of a frequency range of 10 to 200 kHz from a vibrator 3 disposed at a home position on a conveying passage. A treating effect is affected to any material 4a by a substantially equivalent history. And, hence, it is not necessary to set a treating time to a longish time to supplement unevenness of the effect. The treating time by an alkali protease type can be largely shortened. Then, excess consumption and original unit of alkali protease resistance can be reduced. And, an increase in cost accompanied with excess vibration application can be avoided and its cost can be reduced as well.
