Title: PBX with MFC dialling - has tone-to-pulse conversion and special low pass from exchange to outgoing line
IPC: H04Q3/42
Filed: 1972-09-27
Abstract: The private branch exchange with multiple frequency code dialling has a tone receiver to detect dialling signals on an outgoing line, and an external connection unit to pass dialling pulses corresponding to the received tone signals to the exchange line. A special limited-band signal path connects the outgoing line to the exchange line during connection formation. This signal path has an LP filter to suppress the higher harmonics of the signalling tones used for return signalling. The LP filter's cut-off frequency is less than the frequency of the lowest dialling tone.

Title: Stereoscopic photography device and method of projection - using lenticular screen which is simpler than known methods
IPC: G02B30/27
Filed: 1975-09-22
Abstract: A system for producing stereoscopic images, includes a photographic device for recording two dimensional views of an object field, and having a corresponding number of lenses aligned on a rectilinear path so that their optical axes are equally spaced and parallel. A film support places a non-exposed film in an image recording position with respect to the lenses. In the photographic device the distance between the optical axes of adjacent lenses are adjusted as a function of the distance separating the lenses from a selected element of the object field to maintain the image of the selected element formed by each lens in the predetermined position on the associated bidimensional view. These bidimensional views are projected from the predetermined positions of the projection lenses. A lenticular screen is placed opposite the positions so that each lenticules of the screen is essentially aligned with a reference point.

Title: Power supply control circuit
Inventor: LEYDEN MARK
IPC: G05B19/04
Filed: 1995-06-06
Abstract: A power supply control circuit comprises a field effect transistor FET connected between a battery BAT and a microprocessor uP to be powered, and a bistable circuit 11 comprising cross-coupled transistors Q1 and Q2 connected to the power supply and to the switching device. When power is turned on by closing switch SW the circuit 11 assumes a state wherein transistor Q2 is on and transistor Q1 is off so that the current drawn by the transistor Q2 through a resistor R4 provides a voltage drop across the source-drain of the FET sufficient to turn the latter on to allow power to be supplied to the microprocessor. However, upon certain predetermined condition(s) being met the microprocessor turns transistor Q1 on by a signal at its base thereby turning transistor Q2 off so that the FET turns off to remove power from the microprocessor.

Abstract: A transmission test apparatus having a system-clock redundancy system for testing a transmission path is proposed. In the transmission test apparatus, a clock switching unit selects a proper one from a plurality of system clocks in response to a clock selection signal and supplies a selected system clock. A test-signal check unit performs a synchronization operation in which a first test pattern generated based on the selected system clock is synchronized with a test signal coming through the transmission path and compares the first test pattern with the test signal. A synchronization detection unit detects the synchronization between the first test pattern and the test signal by examining the comparison result of the test-signal check unit to produce a synchronization detection signal. An error counter performs a counting operation in which a number of unidentified bits is counted as error bits after receiving the synchronization detection signal. And, an initializing unit initializes, in response to the clock selection signal, the synchronizing operation in the test-signal check unit and the counting operation in the error counter.

Abstract: PURPOSE:To produce a large displacement from a piezoelectric displacement element by coupling an amplitude amplifying horn with a driving side end face of a piezoelectric laminate and setting the length of the laminate and the length of the horn to predetermined lengths. CONSTITUTION:A horn 10 is composed of a columnar unit 20 having the same diameter as a piezoelectric laminate 1, and a trapezoidal conical unit 22 projected through a step 21 from the end face of the unit 20. The laminate 1 is formed by laminating 20 PZT porcelains in the height of approx. 8mm. This height is matched to an equation of nXc1/f, where f: the resonance frequency of the horn, n: integer number/2 (1/2, 1, 11/2...) and c1: sonic velocity in the laminate. Further, the horn 10 has 15mm of entire length, which is matched to an equation of nXc2/f, where c2 is the sonic velocity in the horn 10. The position of the step 21 is disposed at a node position of the amplitude, and the end of the conical unit 22 becomes the maximum amplitude position. Thus, a large displacement can be produced.

Abstract: Circuit protection devices which contain PTC conductive polymer elements and which are used in situations in which the device is mounted onto, or itself comprises, a rigid wall which is spaced apart from the PTC element and through which the electrodes pass. The behavior of the device can be adversely affected if the electrodes, which are prevented from moving by the rigid wall, prevent the PTC element from expanding to the extent necessary to provide the desired PTC effect. The invention includes the use of specially designed electrodes which lessen the danger that the PTC element, when it is tripped, is prevented from expanding to the extent necessary for effective operation.

Abstract: The invention relates to a method and a device for reducing scale formation and/or corrosion in systems which conduct liquids or are in contact with liquids. According to the invention, this is achieved without reducing the quantity of hardness constituents contained in the liquid overall, without exchanging the hardness constituents in the liquid for other cations such as e.g. hydronium, sodium or potassium and without adding chemicals such as e.g. phosphates which inhibit scale formation to the liquid. Instead, scale formation is reduced by specifically shifting the molar distribution of the hardness constituents, especially the distribution proportions of the individual hardness constituents magnesium and calcium strontium and barium. According to the inventive method, proportions of the hardness constituents calcium, strontium and barium in the liquid are substituted with the proportions of the hardness constituent magnesium, In addition to efficiently reducing scale formation, the method inhibits corrosion processes in systems which conduct liquids or are in contact with liquids and reduces the extent of these processes.

Abstract: A multilayer mirror aims to reduce the incidence angle dependence of reflectivity. A substrate 1 is made of low thermal polished expansion glass with 0.2 nm RMS or less roughness of the surface (the upper surface in the drawing). On the surface thereof formed is a Ru/Si multilayer 3 having a wide full width at half maximum of peak reflectivity, and on the Ru/Si multilayer 3 formed is a Mo/Si multilayer 5 having a high peak reflectivity value. Therefore, higher reflectivity than when Ru/Si alone provided and a reflectivity peak having a wider full width at half maximum than when the Mo/Si multilayer 5 alone provided are obtainable. Since Ru absorbs EUV ray more than Mo does, a higher reflectivity is obtainable than that of a structure having the Ru/Si multilayer 3 formed on the Mo/Si multilayer 5. Owing to small incidence angle dependence of reflectivity of a multilayer having a wide full width at half maximum in spectral reflectivity, it is possible to keep high imaging performance in a projection optical system according to the present invention.
