Abstract: An air nozzle for use in the production of nonwoven fabric that is adapted to receive spun filaments from a spinning nozzle and feed the filaments in an air jet onto a receiver. The air nozzle is directed to the prevention of any abrasion of the inner surface of the nozzle body by an additive, such as titanium white, contained in filaments, and thus to the prevention of any defects in the nonwoven fabric. The inner surface of a nozzle body for guiding filaments is formed using a ceramic material to protect that surface. The nozzle body (15) has a conical passage (21) whose diameter gradually decreases from an inlet (19) for receiving the filaments from the spinning nozzle, and a straight passage (23) continuing from the conical passage and extending with a constant diameter, at least part of the inner surface of the conical passage and/or the straight passage being formed as a ceramic surface.

Abstract: A control device for an air conditioner operable in the heating and cooling operation mode is disclosed, which device comprises a "too hot" (1a) and a "too cold" (1b) switch which is operated by the user when he feels that it is too hot or too cold in the room conditioned by the air conditioner. When a first operation of one of these switches by the user takes place, a mode selector (10) automatically selects the operation mode of the air conditioner, and the control of the air conditioner (7 9) is started immediately. The setting or target temperature is automatically renewed every time a further operation of one of the switches is made, so that the target temperature may be adjusted to the individual preference of the user. The fan speed of the air conditioner may also be modified according to the frequency of inputs through the switches.

Abstract: A laser welding system utilizes a multiple axes positioner to angularly orient about orthogonal A and C axes and linearly position along orthogonal X and Y axes a fixtured parts assembly (62) such as to access weld sites at the top, bottom and all sides thereof. Linear ajustments of the position of the laser head (126) along a Z axis are made to maintain a constant beam focal length. Welding in an inert gas environment is thus facilitated, since the welding operation can be completed without human intervention to manually reposition the fixture. Interim purging to restore the requisite welding environment is therefore avoided.

Abstract: A data processing system comprises a number of processing elements, each with its own local memory. The data in the memory is organised into pages, each page being divided into a number of sectors. Each sector has a tag to indicate whether it is valid in the local memory. Pages in the local memory are allocated a demand. When a page is allocated, all the tags for that page are set to indicate that none of the sectors of that page is available yet in the local memory. Individual sectors are copied on demand from remote processing elements into the local memory, and the tag for each copied sector is set to indicate that the sector is now valid in the local memory. The system thus removes the need for page copying, by allowing sector copying which is much quicker, while still retaining the benefits of a paged memory management scheme.

Abstract: variable bit rate coding system has less degradation of the quality of a decoded signal with respect to packet-by-packet signal abandonment to thereby ensure a stable quality and has high coding efficiency. The variable bit rate coding system is characterized in that a sequence of digital signals is divided into signals of a plurality of band areas, and the divided signals are encoded frame by frame. The present system as a whole eliminates the correlation or redundance of the input signal, thus ensuring highly-efficient encoding of the input signal, and maintains the quality of the decoded signal on the receiver side at a constant high level, enhancing the coding efficiency.
