    摘要: The present invention relates to a method of and an apparatus for emitting light in ice, to be applied to an ice skating rink and the like. With the apparatus for emitting light in ice according to the present invention, when light emission sources are light emitting diodes (LED), LED mounting blocks are used and laid on a concrete floor, so that mounting works can be facilitated. Additionally, LED are used as the light emission sources, so that a possibility of ice melting can be eliminated. Furthermore, with the apparatus for emitting light in ice according to the present invention, when miniature incandescent bulbs are used as the light emission sources, the miniature incandescent bulbs disposed in transparent vinyl chloride tubes are laid on the concrete floor, so that a special water-proof measure can be dispensed with. Furthermore, air is delivered into the tube, whereby heat in the tube is prevented from being stagnant in the tube, so that the ice melting is avoided.

    摘要: A plasma density information measuring method capable of easily measuring the plasma density information over the long term, a probe for measuring the plasma density information, and a plasma density information measuring apparatus are disclosed. A measuring probe is set such that a tip end of a glass tube of the measuring probe is brought into contact with plasma PM to be measured. High-frequency power sent through a coaxial cable is supplied to the plasma PM from a loop antenna through a wall of the tube, and reflection power of the high-frequency power is received by the loop antenna to obtain a counter frequency variation of reflection coefficient of the high-frequency power. In the obtained reflection coefficient, a portion thereof in which the reflection coefficient is largely reduced is a peak at which strong absorption of high-frequency power is caused due to the plasma density. The plasma density can be obtained from the plasma absorption frequency.

    摘要: An electret-condenser microphone according to the present invention includes a vibrating diaphragm and a back electrode which compose a condenser; a cylindrical case which houses the vibrating diaphragm and the back electrode; a circuit board which is housed in an opening of the cylindrical case, is fixed to the opening by crimping a crimp edge formed by bending an opening end of the cylindrical case inward, and covers the opening; and a substrate fastened to an outer surface of the circuit board. A circular pattern and annular pattern are formed on the outer surface of the circuit board and a circular pattern and annular pattern are formed on that surface of the substrate which is farther from the circuit board. The circular pattern and annular pattern are connected with the circular pattern and annular pattern via thru-holes in the substrate, and that surface of the substrate on which and are formed serves as a reflow-soldering surface.

    摘要: A plasma generating apparatus and a method for controlling plasma-generating high frequency power capable of appropriately and easily controlling plasma density over the long term are disclosed. Measuring high frequency power is supplied to plasma through a dielectric tube. Apart from a supply system of plasma-generating high frequency power, there is provided a plasma density information obtaining section having long lifetime no hot filament. The plasma density information obtaining section obtains the plasma density information by measuring a physical amount related to reflection or absorption of the high frequency power. An actually measured plasma density monitored by the plasma density information obtaining section from moment to moment and a target plasma density held in a plasma density setting section are compared. Based on this compared result, an impedance matching device is changed, and an impedance matching state between the electric source side and the plasma side, thereby appropriately controlling the generating high frequency power output from the high frequency electric source.
