A dielectric line having a sufficient ensured strength and being suitable for mass production and a production method therefor are provided. The production method is a method for manufacturing a dielectric line having a dielectric strip which is provided between two conductive plates approximately parallel to each other and which has a width smaller than that of the conductive plates, and dielectric medium layers which are filled between the conductive plates other than the dielectric strip and which is composed of a porous material having a dielectric constant smaller than that of the dielectric strip. The dielectric line (NRD guide) is produced by film forming steps S11 and S12 in which a film of a dielectric raw material is formed on one of the conductive plates, a strip exposure step S13 in which a part of the above film having a shape corresponding to the dielectric strip is exposed to predetermined light, beams, or vapor, and pore forming steps S15 and S16 in which the entire film of the dielectric raw material is made porous.

A roots type fluid machine includes a housing, a pair of parallel rotary shafts and two-lobe rotors. Each rotor includes two lobe portions and two well portions. Each lobe portion has a profile of convex arc with a radius R and each well portion has a profile of concave arc which is an envelope of the convex arc of the lobe portion. The rotor has a configuration defined by a curve which includes the convex arc, the concave arc and further an involute curve with a base radius r between the convex and concave arcs. The base radius r is set in a range L/(2√{square root over ( )}2)

In a communication apparatus, effective automatic power control (APC) is realized. Transmission object signal level changing units change a level of a transmission object signal of each channel, and transmission filter units carry out filtering for a signal of each channel after its level was changed with a characteristic for allowing a passage of a frequency component of each channel, and a transmission signal coupling unit couples signals of plural channels after the filtering was carried out, and an antenna transmits a coupled signal by wireless, and coupled signal dividing units divide a part of the coupled signal into a plurality of signals, and level detection filter units carry out filtering for each divided signal with an identical characteristic to the above-described characteristic, and signal level detecting units detect a level of a signal of each channel after the filtering was carried out, and a transmission object signal level change mode controlling unit controls a level change mode of a transmission object signal of each channel on the basis of the detection result.

A starting system for a pump includes a driving motor, an electric source, a selector switch, a starter sensor, a temperature sensor and a control unit. The selector switch is located between the driving motor and the electric source for reversing polarity of the electric power supplied from the electric source to the driving motor. The starter sensor senses whether or not the driving motor has been started. The temperature sensor senses a temperature. The control unit operates the selector switch so as to repeatedly give the driving motor indications of reverse rotation and normal rotation in a case where the starter sensor does not sense that the driving motor has been started even if the control unit operates the selector switch so as to give the driving motor the indication of normal rotation in a state where the temperature sensed by the temperature sensor is below a preset temperature.

The present invention provides a vibration wave driven motor or actuator in which a discontinuous coupling member is provided between a vibration member and a load to be driven by a movable element. The coupling member blocks undesirable travelling wave to decrease the noise and prevent the lowering of the output.

The present invention provides a contact probe pin in which a carbon film having both of conductivity and durability is formed on a base material with a tip divided, wherein Sn adherence can be reduced as much as possible to be able to maintain stable electrical contact over a long period of time, even under such circumstances that the temperature of a usage environment becomes high. The present invention relates to a contact probe pin, including a tip divided into 2 or more projections and repeatedly coming into contact with a test surface at the projection, wherein a carbon film containing a metal element is formed at least on a surface of the projection, and a radius of curvature at an apex part of the projection is 30 μm or more.

A blood purification instrument for extracorporeally circulating a patient's blood and a concentration detector detects a concentration of liquid during blood purification wherein the concentration detector has a light emitter irradiating light onto the liquid, a light receiver receives the light as transmitted through the liquid, a reference light receiver receives reference light branched from the light emitter without transmission through the liquid, and a detector detecting the light intensity respectively of the transmitted light and the reference light received by the light receiver and the reference light receiver, respectively. The blood purification apparatus further includes an error corrector detecting the concentration of the liquid based on the received light intensity of the light received by the light receiver and detected by the detector and for correcting a detected error of the concentration detector based on the received light intensity of the reference light received by the reference light receiver.
