Abstract: A swimming pool treatment device comprises cylidrical pills comprising solid water treatment material such as trichloroiso­cyanuric acid. A collar is surrounds the per­iphery of the pill so that only the end surfaces thereof are engaged by the water. Consequently there is a constant erosion of the pill material. Various containers for one or more pills are disclosed. The containers which rest on the pool floor have downward projections that permit sufficient water flow below the pill container to prevent staining of the pool floor.

Abstract: There is disclosed an information input and output apparatus comprising an active matrix type display device and switching means. In the information input and output apparatus, the display device displays an image according to an image signal, and has plural pixel electrodes formed in a matrix shape on a transparent substrate. The switching means drives the display device responsive to a predetermined voltage to be applied to one of row electrode lines and a predetermined voltage to be applied as the image signal to one of column electrode lines. A photoconductive layer is formed between each of the row electrode lines and each of the column electrode lines at each intersection of the row electrode lines and the column electrode lines so as to receive light projected from the light pen. When light projected from a light pen is incident onto the photoconductive layer, the resistance thereof decreases. Then, a detection circuit detects a position of the light pen located on the display means responsive to a signal corresponding to the decrease of the resistance of the photoconductive layer which is induced to each of the column electrode lines.

Abstract: A centrifugal fan includes a brushless d.c motor (50), an impeller (60) mounted on the motor and a scroll (70) on which the motor is mounted. The scroll defines the air inlet and outlet (73) and has an outer wall (71) curved around the impeller to define a divergent air flow path. By truncating the scroll at the outlet substantially to eliminate any flat portions on the outer wall susceptible to mechanical vibrations at frequencies excited by the d.c motor, a noise reduction is achieved. Further noise reduction may be achieved by resiliently mounting the motor on the scroll.

Abstract: A disk file with a conventional slider and a disk with an essentially carbon protective overcoat is cycled on and off at a frequency such that the slider is maintained in contact with the disk. Alternatively, the disk is rotated at a low constant speed so that the slider is maintained in contact with the disk. In both cases, carbon is transferred from the carbon overcoated disk to the air bearing surface of the slider, depositing a thin protective carbon film on the air bearing surface of the slider. During subsequent operation of the disk file, the disk file has excellent durability, especially when operated at relatively low humidity, as is required in those disk files which use a magnetoresistive sensor on the slider.

Abstract: A Stop On Station (SOS) circuit (120) of an AM/FM radio receiver (100) comprises means (118,207) for measuring the amplitude and frequency of a candidate radio signal. The frequency measuring means (207) comprises a counter (207) and a decode circuit (209,210) to detect the deviation in frequency of the received signal with a centre reference frequency. A persistence counter (229) determines the stability of the frequency over a plurality of samples and outputs a frequency output signal if this is within acceptable limits. The signal strength measuring means (118) compares the strength of the signal with a reference value and outputs a strength output signal if the measured strength is greater than the reference value. Generation of both the frequency and strength output signals causes the candidate radio signal to be selected for listening to. 
     A noise measuring circuit (117) is used when FM signals are being tested and outputs a noise output signal if noise is within acceptable limits. Generation of all three output signals, noise, frequency and strength, causes the FM candidate signal to be selected for listening to. 
     If one of the criteria is not met for the candidate radio signal, an alternative candidate signal is selected for testing.

Abstract: A control circuit for alternating current motors comprises a bidirectional controlled diode (TRIAC) connected in series to the motor and with its own control terminal connected to a fixed-phase actuating network in order to supply partial power to the motor. The control terminal is also connected to a switching device, piloted by a control signal to supply it, when closed, with a bias current which causes the continuous operation of the TRIAC, so as to supply full power to the motor. 
     The control circuit can be used in conjunction with circuits which measure the current absorbed by the motor and give said control signal to make it switch from the full power condition to the partial power condition and vice versa whenever said current reaches pre-established thresholds. 
     One of these circuits supplies partial power to the motor whenever the current is absorbs is too high, which indicates a mechanical overload. Another circuit supplies partial power to the motor whenever the current it absorbs is too low, which indicates no-load operation, so as to prevent overspeed.

Abstract: A biodisintegrable thermoplastic resin foam and a process for producing same are disclosed, the biodisintegrable thermoplastic resin foam being comprised as a substrate thereof a mixed resin comprising 5-40 weight % of a thermoplastic resin decomposable by microorganisms and 95-60 weight % of a thermoplastic resin not decomposable by microorganisms and being characterized in that the individual aerial cells constituting the foam have an average cell wall thickness of 1-100 µm and an apparent density of 0.5 g/cm³ or less than 0.5 g/cm³. The biodisintegrable thermoplastic resin foam is easily disintegrable after disposal in an environment where microorganisms exist so that it can be reduced in bulkness and gives no harmful effect on the life of natural plants and animals. The foam incorporated with a filler can be promoted in disintegration by microorganisms. Thus the present invention affords an effective means for solving various problems in the treatment of disposed materials.

Abstract: An optical system of a NX reduction catadioptric relay lens having sub-half micron resolution over the ultraviolet band width is described. A spherical mirror (16) with a stop at the mirror is used to work at substantially the desired reduction ratio and the desired high numerical aperture sufficient to provide the desired high resolution. A beam splitting cube (22) with appropriate coatings (20) is used to form an accessible image of an object (6) on an image plane (8). Refracting correctors (7, 9) in the path of the slow beam incident on the mirror and in the path of the fast beam reflected on the mirror are designed to fix the aberrations of the image formed by the mirror. The beam splitter coatings are chosen in such a way that beams reflected from and transmitted therethrough suffer no net aberration as a result of multiple reflections within the thin film beam splitter coatings and therefore are substantially free of aberration, distortion and apodization which would result from the beam splitting surface in the absence of these coatings.

Abstract: A video picking and clipping method and apparatus are described. The picking method and apparatus comprise: A CPU and a direct memory access (DMA) circuit which is used with a graphics microprocessor (GµP) for virtually redrawing a display list from a system memory of objects in a bit map. A starting address and a number corresponding to the number of instructions in a segment comprising a plurality of display lists are sent to the DMA for this purpose. When the coordinates of a pointer match the coordinates of a selected data object, a pick interrupt signal and special pick instruction is sent to the CPU. The CPU then uses the starting address of the display list of a selected object from a table to generate a new display list to perform a pre-selected operation on the selected data object. The clipping method and apparatus comprise a plurality of data planes for storing data objects, a match plane for storing a clipping object and a one-bit register. In use, the pixels in the data and match planes are scanned. When a match occurs between a pixel in the match plane and the contents of the one-bit register, a match signal is generated. The match signal enables the data planes to re-store the corresponding pixels of the data objects in the match planes.
