A compressor includes a discharge chamber, a compression chamber, a partition wall, and a discharge reed valve. The partition wall is arranged between the discharge chamber and the compression chamber and includes a fixing surface facing the discharge chamber. The partition wall includes a discharge port that communicates the discharge chamber and the compression chamber. The discharge reed valve includes a fixed portion, an intermediate portion, and a valve portion. The fixing surface includes a first groove portion, which extends around the discharge port, and a valve seat surface, which is arranged between the discharge port and the first groove portion. The first groove portion extends to a range overlapped with the intermediate portion. A part of the valve portion at a distal side does not close the first groove portion. The valve seat surface includes a receiving portion.

The present invention provides an optical receptacle having a superior insertion/extraction performance of the ferrule, and an optical sub-assembly applying the optical receptacle. The optical receptacle 1 includes a stub, a bush 4, a sleeve, and a sleeve cover. The stub having a lower portion covered by the bush, and an upper portion covered by the sleeve. The sleeve may be a rigid sleeve without any slit along the optical axis in its outer surface. The sleeve cover covers the sleeve and the bush. In the present optical receptacle, the bush is press-fitted into the gap formed between the stub and the sleeve cover. Accordingly, in addition to the application of the rigid sleeve, not only the sub is hard to slide out from the sleeve, but also the insertion/extraction performance of the ferrule to be inserted into the sleeve may be enhanced.

A take-up rate and a let-off rate in warp feed on a loom are controlled while a displacement (.DELTA.L) of a cloth fell position C is taken into account. The system comprises a cloth fell position compensation circuit (2, 16, 21) which outputs a cloth fell compensation signal (.DELTA..omega..sub.c) to compenate a displacement (.DELTA.L) of the cloth fell position (C) when a weaving condition such as a target weft density (D*), a target warp tension (T*) or the kinds of weft and warp yarns is changed. The cloth fell compensation signal is added to a basic warp feed rate (.omega..sub.f) obtained from D*, so that the displacement motion of the cloth fell is completed in a shorter time. According to this compensation, a weft density of a resultant fabric rapidly coincides with the target weft density.

A coating quality measuring device and a pattern plate including one reference pattern portion having a large pattern width and a plurality of strip pattern portions each having a smaller pattern width. The pattern plate is disposed opposite the coated surface. The pattern plate is reflected off the coated surface and a reflected image is formed on an image sensor. The image sensor successively outputs signals each corresponding to the light level of each strip pattern portion on a line extending in a width direction of each strip pattern portion of the reflected image. A computing device calculates an average signal level of the signals outputted by the image sensor, divides the difference between the average signal level and the signal level of each signal by the signal level of the reference pattern portion and calculates a square average value of the obtained division value to obtain a measure of the coating quality of the coated surface.

A device for inserting a weft yarn in a shed of the jet operated weaving machine provided with a control means for controlling the carrying action of the weft yarn, which is carried by a plurality of pressure fluid flows through a guiding channel formed in a comb arranged in parallel condition to a reed. The comb comprises a plurality of guiding plates and an air escaping passage formed between every two adjacent guide plates in such a condition that the quantity of the escaping air which flows through each escaping passage is maximum at a predetermined portion of each escaping passage. The above-mentioned control means comprises the above-mentioned escaping passages.

The ferrule part 16 comprises ferrule 60, first and second optical fibers 62 and 64, and optical filter 68. Ferrule 60 has first and second end surface 60a and 60b, ferrule insertion hole 60c, and groove 68. Ferrule insertion hole 60c extends along a first axis, and accommodates first and second optical fibers 62 and 64. Groove 66 extends along a second axis crossing the first axis, and extends so as to extend across ferrule 60. Groove 66 is provided along a plane defined by the second axis and a third axis perpendicular to the first and second axes. Optical filter 68 can reflect a part of light incident on one surface 68b of the pair of surfaces of optical filter 68, and can transmit a part of the light incident on other surface 68a.

A jet loom comprising a weft measuring roller for continuously drawing out a weft from a supply package, a weft storage unit for temporarily accumulating and storing the weft drawn out from the supply package by the weft measuring roller, a main nozzle for jetting air to insert the weft into the warp shed, and a driving unit for sinusoidally varying the rotating speed of the weft measuring roller. The weft stored in the weft storage unit runs in a free running period in a free running mode at a comparatively high running speed. After the stored weft has exhausted, the weft is supplied for insertion directly from the weft measuring roller, so that the weft runs in a constrained running mode at a running speed constrained by the surface speed of the weft measuring roller. When the running mode of the inserted weft changes from the free running mode to the constrained running mode, the driving unit drives the weft measuring roller so that the surface speed of the weft measuring roller is higher than a speed Vf defined by: Vf=Lo/tc, where Lo is the weft length of the loom and tc is a time necessary for one weaving cycle of the loom.

摘要:
A package construction has electrodes of a double layer capacitor element located on the opposite sides of the element. All of the electrodes are led out in the same direction. A pair of electrode plates are disposed on the element with an insulator plate having a through-hole interposed between the two plates. A terminal of an inner electrode plate penetrates through the through-hole in the insulator plate and through an aperture formed in the outer electrode plate. The capacitor is assembled in such manner that the inner electrode plate is electrically connected to one electrode of the element, while the outer electrode plate is electrically connected to the other electrode of the element via a conductive casing.
