Abstract: PURPOSE:To realize a transducer having high stability and high accuracy, by executing addition and subtraction of plural DC voltages being proportional to a power of a phase difference of 2 AC inputs, and reference voltage, in a prescribed ratio, so that DC voltage being proportional to a power-factor can be outputted. CONSTITUTION:Each AC input of a phase difference (phi) of a terminal 1 and 2 becomes square wave voltage by a comparator 11 and 12, exclusive OR is taken by a gate 13, and it becomes sqaure wave voltage 53 of a duty ratio being proportional to the phase difference (phi). The voltage 53 is applied to switches S1, S2, S3 and S4, and S1 makes reference voltage Ez pass through when the voltage 53 is high, and an output 61 of a peak value Ez passes through a filter A and is converted to DC voltage E22 being proportional to the phase difference (phi). In the same way, DC voltages E22-E24 being proportional to powers phi<2>, phi<3> and phi<4>, respectively, of the phase difference (phi) are obtained. Subsequently, the voltages E22, E24 and Ez are subjected to addition and subtraction in the prescribed ratio by an adding and subtracting circuit AD, and an output E25 being proportional to a power-factor of an input is obtained.

Title: Tube for multitubular type heat exchanger and manufacture thereof
Inventor: ADORUSU SUUOCHIRU
IPC: F16L9/128
Filed: 1989-06-14
Abstract: PURPOSE: To improve durability by covering a tube with a heat-resistant and corrosion-resistant layer comprising fibers and fluorine-containing polymer applied to fiber surfaces. CONSTITUTION: On a tube comprising PTFE, a heat-resistant and fluorine- resistant layers comprising fibers and fluorine-containing polymer applied to fiber surfaces are covered.

Abstract: PURPOSE:To reduce the extent of contamination of a sample housed in the inner part of a reaction processing chamber by installing a temperature control means in a valve plate, in a gate valve with the valve plate opening or closing the reaction processing chamber or the like of a semiconductor manufacturing unit. CONSTITUTION:A heating member 12 composed of a heating wire or the like as a temperature control means and a cooling member 13 composed of a cooling pipe or the like, where water or the like flows, are embedded in a second valve plate 5 at the side of a reaction processing chamber.

Accordingly, the valve plate is set to the temperature that a reaction product is heard to be stuck, whereby any possible sticking of a contaminant to the valve plate 5 is reduced. Consequently, the rescattering contaminant due to friction and vibration by drive of the valve plate 5 also becomes very lessened, and moreover, at optional time, the setting temperature is raised and thereby the contaminant can be burned and eliminated as well.

IPC: B25B21/02
Filed: 1991-06-25
Abstract: PURPOSE:To reduce the friction loss of the rotary cylindrical member and thereby increase the transmission efficiency of the torque, by keeping the rotary cylindrical member out of contact with the two hammers excepting the time when its two engaging projections collide against the two hammer members. CONSTITUTION:A rotary cylindrical member 5 is formed, at its inner circumferential surface 5b, into a true-circular surface, and this inner circumferential surface 5b is integrally formed, at its suitable portions, with engaging projections 8a, 8b radially inwardly projecting therefrom in the longitudinal direction. The rotary circumferential member 5 has on its inner circumferential surface a steel ball 16 which is rolling on an inner surface trajectory in a guide groove 10a of the member 5 in a condition of being floated from a hammer 12a due to the centrifugal force. The member 5 is only in a point-contact with the steel ball 16 and therefore is in rotation with a small friction loss. Even when engagement between the engaging projections 8a, 8b and the hammer members 12b, 12a occurs, the rotating force maintaining that engagement is only instantaneously produced and this engagement is soon released. Thus, both are engaged together after one full re-rotation of the member 5, for which reason the engagement occurs impact-wise.
