Abstract: An improved human motion applicator assures a quick and sufficient amount of displacement given to a part of a human body. The applicator includes a support adapted to be fifted on the part of the human body. The support carries at least one electro-active elastic actuator in a force-transmitting relation to the human part. The actuator includes a dielectric core and a pair of electrodes on opposite of the core for receiving a driving DC voltage thereacross. The elastic actuator has a length and elastically deforms in the lengthwise direction to exert a stretching force to the human part to a greater extent as the driving DC voltage increase. The applicator also includes a controller which applies the driving DC voltage of varying levels to the elastic actuator, thereby generating a varying motion-inducing force to be applied to the part of the human body.

Abstract: Dynamic quantitative displacement is converted stably and straight into voltage (D.C. output) by using a high speed detection driving frequency without restricting a response of an operational amplifier. When a dynamic quantity detection electrostatic capacitance changes according to a dynamic quantity, electric charges stored in this element and in a reference electrostatic capacitance become unbalanced to produce a difference value, and an output of an operational amplifier changes according to the difference in electric charge quantity. However, the output becomes finally stable when the electric charges in the dynamic quantity detection electrostatic capacitance and in the reference electrostatic capacitance become equal. The output is proportional to a reciprocal of the dynamic quantity detection electrostatic capacitance and it is a D.C. voltage. Further, output without depending on integration feedback capacitance (feedback condenser) CF can be obtained.

Abstract: In a capacitance type pressure sensor, a diaphragm is formed of a fragile material using an impurity-diffused monocrystal silicon and constitutes a stable pressure-responsive structure which does not undergo a plastic deformation. Between the diaphragm and a movable electrode is formed an oxide film to diminish stray capacitance between the movable electrode and a substrate and also between the movable electrode and a impurity-diffused layer. The oxide film and the movable electrode are each divided into plural regions so that the divided regions of the movable electrode are formed on the divided regions of the oxide film, thereby diminishing stress strain induced by a difference in therm expansion coefficient among the diaphragm, oxide film and movable electrode.

Abstract: In CVD processes susceptors can be made of a thermally conductive ceramic such as aluminum nitride which has superior durability with respect to fluorine plasma. Such aluminum nitride susceptors can include an embedded heater element and/or embedded ground or RF electrodes which as a result of their embedment are protected from the deleterious effects of the processing chamber environment. The conductors leading to these elements are protected from exposure to the process chamber environment by passing through a cylindrical member filled with inert gas supporting the wafer support plate of said susceptor. Alternately, the conductors leading to these elements can be run through passages in a hermetically sealed stem supporting the susceptor wafer support plate. The stem passes through the wall of the processing chamber so that connections to the susceptor wafer support plate can be made outside the processing chamber.
