Patent EP-0220867-A2 (EP)
Inventor: HAYASHI TOSHIHIDE C O SONY COR
IPC: H01Q21/24
Filed: 1986-10-10
Abstract: Apparatus for receiving satellite broadcast signals having different planes of polarisation for adjacent or odd-numbered and even-numbered channels, respectively, comprises a receiving unit (1), a switching unit (2) for changing over the receiving plane of polarisation, and a controller (3) for controlling the receiving unit (1) and the switching unit (2). The apparatus is operative, upon sequential channel selection, sequentially to select alternate or every other channels, for example the odd-numbered channels, having a first plane of polarisation, and then automatically to switch the receiving plane of polarisation of a polariser and sequentially select the other alternate channels, for example the even-numbered channels, having a second plane of polarisation. Thus, the user does not have to switch the plane of polarisation of the polariser for receiving the satellite broadcast signal and the plane of polarisation of the polariser needs to be changed only once when scanning the full array of channels so that channel selection can be carried out at high speed.

Abstract: The point at which pump out pressure exceeds load is sensed to provide a point for scheduling flow to an actuator in a hydraulic system, such as an elevator. Flow is controlled by a stepper motor (28) that moves a flow control valve (27). When the pump (21) is turned on, the valve (27) is positioned to bypass flow; the bypass flow is then programmably decreased to increase the flow to the actuator. Reverse flow is regulated by the valve (27) to control actuator retraction. Reverse flow is initiated by opening a check valve (40) with an actuator (50) that opens it first to reduce pressure across the valve, then fully. The flow control valve (27) also operates to relieve excess pressure in the system.

Abstract: A self-centering steady rest according to the invention intended to improve the present technical ability of a steady rest to center a round workpiece with greater accuracy. This is achieved by virtue of the fact that the steady rest has three gripper pivot arms with support rollers, said pivot arms having the same bending stiffness regardless of its gripping force and that one of the pivot arms has an extended opening movement so that the workpieces of approximately the maximum gripping diameter can be easily inserted and removed from the steady rest with the bridge loader. Moreover, the gripping force of the pivot arms can be adapted to the value required to make the workpiece center and thus the life of the support rollers can be appreciably increased.

Abstract: A character generator with multidirectional scan and variable line and character (or symbol) size capability is disclosed. Universality is implemented by producing a serial binary stream which can be used to print or display in any of eight combinations of scan direction and progression, that is, for scan direction left to right, or vice versa, progressing up or down, or scan direction top to bottom or vice versa, progressing left or right. In formatting the serial binary stream, a font is accessed (for basic symbol definition), which selectively provides for orthogonal scans of the symbol definitions. Variable line size is implemented by terminating a symbol row (or line) based on a predetermined size criteria regardless of the comparable font dimension and "filling" up to the line size to the extent the corresponding font dimension is less than the predetermined size criteria. Variable character (or symbol) size is implemented by independently multiplying the effect of a symbol definition by selected (integral) factors, in orthogonal directions. The general architecture includes a font table (for symbol definition), an address/escape (A/E) table, defining symbol size for comparison with line size parameters, a character position escape (CPE) table to define a leading character or symbol on each line and a page buffer (PB) memory defining the characters (symbols) in the document and their relationship with other characters (symbols). Access to the CPE table allows access to the PB, from there to the A/E table and from there to the font allows extraction of selected and appropriate portions of the symbol definition to make up the binary system.

Abstract: The container according to the invention is constituted by a box-like, for example parallelepipedal, body (1) which is closed by a practically non-removable cover (2), accommodating the device (3) for the removal of the needle from the syringe. The device (3) is composed of a rectangular opening (4) having its shorter side (7,8) slightly longer than the diameter of the conical tang of the needle which is removably associated with the tab of the syringe. The opening is practically closed by an elastic blade (5) which, besides preventing the accidental exit of needles from the container (1), also acts as a spring to engage the conical tang (18) of the needle (17) at a side (21) of the opening, allowing the removal of the needle from the syringe (16) by simply inclining the latter of a small angle.

Abstract: A temperature history indicator includes a region 6 with a hydrophobic organic compound enclosed in microcapsules. If the temperature rises higher than a certain value, the compound melts and diffuses, causing a dye-precursor and a color developer to contact each other to irreversibly achieve color development. This color development system 7 is rendered operative when the high temperature rise continues for a predetermined time period. The top of the color development system is coated with a transparent material 11 with a bonding agent 8 arranged so as neither to break those chemical compositions which cause the color development nor to lower their color developing function.

Abstract: A vortex shedding bluff body for generating vortices in a fluid flowing through a passageway within which the bluff body is supported. The bluff body extends only partially across the width of the passageway such that a significant proportion of the fluid flow occurs between the free end of the bluff body and the side of the passageway towards which the bluff body extends. A relatively short bluff body extending for example only one fifth of the way across a passageway can generate vortices the characteristics of which enable an accurate measurement of the fluid flow rate to be derived. This means that the introduction of a vortex shedding bluff body need not significantly reduce the carrying capacity of the pipe into which it is introduced.

Abstract: A motor speed control system takes one approach to establish dummy load models having characteristics  equivalent to an electric motor to be controlled. One of the dummy load model is established for feedback :controlling the electric motor on the basis of the speed of the dummy model. The dummy model is divided into first and second models. The first model is designed to have equivalent characteristics to output a first motor speed representative data. The current to supply to the first model is so adjusted as to reduce a difference between the motor speed representative data and a desired motor speed data to zero. A frequency signal is added to the current applied to the first model and supplied to the electric motor to drive the latter. The second model receives the frequency signal to output a frequency signal dependent second motor speed representative Ivalue. Sum of the first and second motor speed representative value is compared with a measured motor speed indicative value to derive a speed difference compensation value based on the error therebetween. Based on the speed difference between the sum value and the measured motor speed and the frequency signal, intertia condition on the motor is assumed for controlling transfer characteristics so that the inertia condition in the first model becomes coincident with that of the motor.

Abstract: The present invention describes a robust register circuit for protecting critical control points in data transmission and telecommunications equipment against software included failures. A circuit is provided wherein duplicated data words are written into a pair of registers of any desired bit length. A digital comparator determines whether the two data words are the same, and initiates a data transfer into a third register for transmission to critical hardware control points only when two identical sequential data words are recognized. When no such recognition occurs, new data is not transferred to the third register, and the hardware control points remain controlled by the previous data in the third register.
