An apparatus for cutting a veneer piece into equal sections includes a main conveyer for feeding the veneer piece in a direction transverse to the wood fibers thereof and a cutter disposed in the main conveyer for cutting the veneer piece along the feeding direction thereof. A straightening unit is provided at the upstream position of the cutter for controlling the orientation of the veneer piece on the main conveyor in such a manner that the fibers precisely extend along the transverse direction of the main conveyer, the unit including a plurality of retractable stoppers capable of projecting from the main conveyer to stop the veneer piece for a predetermined time. A multiple conveyer system extends from the downstream end of the main conveyer to transport the sections of the cut veneer pieces to a single feeder at different timings, the feeder conveying the sections to an apparatus for forming seam plates.

An FM receiver provided with an array of antennas and suitable for use in a moving vehicle such as a motorcar, which is provided with means for automatically avoiding multipath noises. The means so operates as to connect one of the antennas in an instantaneously best sensing condition to an FM tuner.

Each of the washing units A and B comprises an openable and closable pinch valve unit 4 branchwise connected to a pipeline C, an autofeeder unit 5 for controlling the feed for advance and retraction movement of a high pressure hose 6 having rotatable nozzle unit connected to the front end thereof, and a hose reel unit 7 for winding and unwinding the high pressure hose. During washing operation, the nozzle unit enters the pipeline C through the pinch valve unit 4 now opened to wash the inner surface of the pipeline. During nonwashing period, the nozzle unit is moved rearward and completely isolated from the pipeline by the pinch valve unit 4 now closed. Therefore, the washing units A and B are completely separated from the pipeline C during nonwashing period.

A complex antenna system including at least two loop antennas crossing each other and connected with each other at the electric neutral points thereof, and a rod antenna positioned at the central portion of the loop antennas. An FM and/or AM tuners combined with the complex antenna system utilizes selected one of the loop antennas for receiving an FM wave so as to avoid multi-path noises.

In a multilayered optical thin-film filter having multiple quarter wavelength thick optical thin films with different refractive indices, the filter includes a plurality of unit cavities that are stacked multiple times via a connection layer, each unit cavity including a first reflector layer, a spacer layer in contact with the first reflector layer, and a second reflector layer in contact with the spacer layer. The first reflector layer is a layered body and the second reflector layer is a layered body. The spacer layer is a multilayered optical thin film with a high refractive index obtained by layering even number of films, or is composed of a multilayered optical thin film with a low refractive index. The connection layer is a multilayered optical thin film with a low refractive index obtained by layering odd number of films.

A distributed element filter is realized which has bandpass characteristics realizing both a flat amplitude characteristic and a flat group delay characteristic throughout the passband at the same time, while realizing transmission zeros in the stopbands. The transfer function s21 of a lowpass prototype filter is expressed by a numerator rational polynomial f(s) having at least one conjugate zeros on the real axis and one conjugate zeros on the imaginary axis and a denominator rational polynomial g(s) as a Hurwitz polynomial of degree 6 or higher; circuit blocks corresponding to the zeros on the real axis and zeros on the imaginary axis are each realized by a multiple resonator filter, and the distributed element filter is realized by a multiple coupling circuit block by setting the conditions on each coupling in corresponding relationship to the zeros on the real axis or zeros on the imaginary axis. The filter having the desired bandpass characteristics can thus be constructed and realized with simple circuitry by using a strict design procedure.

A mounting system that is capable of effectively draining the rainwater off the roof, while enabling easy installation of the solar battery modules. The mounting system is adapted to install on the roof an array of the solar battery modules each of a panel-like configuration with a rectangular frame. The system includes a plurality of vertical rails which are secured to the roof and extend along a roof sloping direction towards eaves from a ridge of the roof for holding the solar battery modules between a laterally spaced pair of the vertical rails in a spaced relation from a roof sheathing. Each of the vertical rails is formed on opposite sides thereof respectively with stepped shoulders which extend the full length of the vertical rail for supporting thereon the frame of the laterally adjoining solar battery modules. The vertical rail is further formed on opposite sides thereof with respective trough sections which extend the full length of the vertical rail and are disposed below and outwardly of the corresponding stepped shoulders for receiving the rainwater sneaking along the frame. Thus, the rainwater is effectively prohibited from reaching the roof sheathing and advancing through the roof into interior of the house.
摘要:
Means is disclosed for washing the inside of a pelletizing machine containing a bag filter which is capable of being raised and lowered within the body of the machine. A vertically movable, upright means to spray washing liquid in three dimensions is provided above the bag filter. A horizontally movable spraying means is provided below the bag filter. This horizontal spraying means can be retracted from inside the pelletizing machine during pelletizing operations, but is capable of spraying washing liquid upwardly into the open end of the bag filter during washing operations.

The cleaning nozzle of the invention is intended to clean the parts to be cleaned by the cleaning water, by feeding cleaning water into the cylinder tube, pushing out the injection nozzle from the mounting surface by the pressure of the cleaning water, and injecting cleaning water while rotating at the same time. Next, when the feed of cleaning water is stopped, the injection nozzle stops injecting cleaning water, and is simultaneously retracted into the housing, thereby closing the mounting part by the poppet valve.
