During joining, while the inversion plate is inserted in a recessed portion of the connecting member and an opening of the recessed portion faces upward in a vertical direction, a boundary at which an inner wall surface of the recessed portion faces an outer side surface of the inversion plate is continuously radiated with a laser beam from above by one round or more. The inner wall surface in a circular shape of the connecting member is an inclined surface inclined further apart from the outer side surface of the inversion plate as the inclined surface is located closer to the laser beam radiation side, and the inclined surface satisfies w / (h·D)≧0.002 (w: a length of the inclined surface in a radial direction, h: a height of the inclined surface, D: a diameter of the inclined surface on an opposite side to the laser beam radiation side).

Upon detecting an external signal which instructs to stop discharge, an input voltage equal to or less than a set value for the prevention of overdischarge, or an output voltage equal to or more than a set value for the prevention of output of an overvoltage, a control unit (12) stops discharge to a load (40) by opening a switching element (4b) of a step-down unit (11b). Upon detecting that an external signal is reset or an input voltage equal to or more than a set value larger than the set value for the prevention of overdischarge, the control unit (12) resumes discharge to the load (40) by setting the switching element (4b) in a switching operation state or short-circuiting it.

A high-order harmonic device of a cavity filter including a base and a lid cover the base is disclosed. The base has a through groove connecting to an upper and a lower portion. The base has a plurality of output terminal with metallic conductor extending into the inner side formed on the surface of the sidewall. The base has resonance space formed indented to receive the metallic conductor and extending to connect to the through groove. The lid has a plurality of threading holes formed corresponding to chambers and partitions received with adjusting elements for height adjustment. The adjusting elements has the resonance bars corresponding to every chamber and the suppressing bars corresponding to every partition. By adjusting suppressing bar and the partition to a predetermined distance, the space of the channel for transmitting the high-order harmonic wave can be reduced to suppress noise produced by high-order harmonic wave.

The invention discloses an ISGW broadband band-pass filter with double transmission zeros and wide stop-band, which comprises an upper dielectric plate, a lower dielectric plate and a spacer dielectric plate arranged between the upper dielectric plate and the lower dielectric plate. The upper surface of the upper dielectric plate is printed with a first copper-clad layer. The lower surface of theupper dielectric plate is printed with circular metal patches, and a first metal through hole is formed in each circular metal patch to form an artificial magnetic conductor structure. The upper surface of the lower dielectric plate is printed with a second copper-clad layer which is provided with three pairs of U-shaped slots. The two ends of the second copper-clad layer are respectively connected with a transition gradient line and a feeding micro-strip line for realizing impedance matching. The lower surface of the lower dielectric plate is printed with a grounded third copper-clad layer, and periodically arranged second metal through holes and third metal through holes are respectively formed in the two sides and middle of the third copper-clad layer to realize a filtering function. The ISGW broadband band-pass filter can suppress space radiation and plane wave and achieve high integration and miniaturization, and has the advantages of small size, easy integration and stable structure.

To provide a device for processing a substrate capable of suppressing a device-space required for opening and closing a cover. The cover 62 is slightly raised from a state with the cover 62 press contacted to a chamber body 61 in air-tight manner by actuating elevating motors 107 and 127. Next, the cover 62 is slide moved holizontally along guide rails 201, 202 arranged at different heights on both sides of a processing chamber 60. After the cover 62 is slid to a position deviated from a chamber body 61, the cover 62 is lowered and rotated at the position after it is lowered.

The semiconductor laser device includes a cavity structure having a first clad layer, an active layer and a second clad layer formed on a substrate. The second clad layer has a stripe portion extending between the front end face from which laser light is extracted and the rear end face opposite to the front end face. The stripe portion has a first region located closer to the front end face, a second region located closer to the rear end face and a change region whose width changes located between the first and second regions. The effective refractive index difference between the inside and outside of the stripe portion in the change region is greater than that in the first region.

Ultra-cold (nano-Kelvin) neutral atoms can be trapped, manipulated, and measured, using integrated current carrying micro-structures on a nearby surface (Atom Chips). This can be utilized for the realization of ultra-sensitive sensors and quantum computation devices based on the quantum mechanical properties of the trapped atoms. However, harmful processes arise from the interactions between the atoms and the nearby surface. According to the present invention these harmful processes can be highly suppressed by using electrically anisotropic materials. It is shown that time-independent trapping potential corrugation leading to fragmentation of the trapped atom cloud can be suppressed, and that time dependent noise processes arising from the coupling of atoms to the nearby surface, and leading to loss of atoms from the trap, heating and loss of coherence can be significantly reduced.

An image forming apparatus comprising: a paper feeding cassette which selectively stores at least two kinds of paper sheets having different size with respect to a paper feeding direction, and includes a posterior end cursor which restricts a posterior end position of the stored paper sheets with respect to the paper feeding direction, wherein the height of the posterior end cursor is changeable. According to this construction, a smaller space is provided to stack large-sized paper sheets which are not frequently used while a larger space is provided to stack small-sized paper sheets which are frequently used can be reserved.
