Inventor: TOMITA NAOTO C O INTELLECTUAL
IPC: G11C8/18
Filed: 1994-06-24
Abstract: A semiconductor memory circuit includes a memory cell array (3) having a plurality of memory cells. Column selection lines (BT) constitute connection lines extending from the memory cell array and are divided into hierarchies like a tree by selecting transistors (11). More specifically, a column selection system is hierarchically divided into column selection lines belonging to a first-stage column decoder (121) and a second-stage column decoder (122). Row selection lines are controlled by a row decoder (4). The semiconductor memory circuit also includes an ATD circuit (7) for detecting a transition of an address signal to generate a pulse , a pulse width control circuit (8) for controlling the width of the pulse to determine data in a sense amplifier (5), and a latch circuit (9) for latching readout data in response to the width of the pulse. A delay means is provided in the first-stage column decoder (121) of an upper hierarchy to which a small number of selecting transistors (11) belong and from which a signal rises at high speed. The delay means of the first-stage column decoder (121) causes the pulse from the ATD circuit to always operate the latch circuit (9) earlier than the timing of transition of data in the sense amplifier (5), thereby latching the preceding data.

Title: Carrier recovery circuit for offset QPSK demodulators
Inventor: CHIBA KENICHIRO C O NEC CORPOR
IPC: H04L27/00
Filed: 1994-08-04
Abstract: The present invention relates to a carrier recovery (CR) circuit for recovering carriers from offset quadrature phase shift keying (O-QPSK) modulated carriers, in which each of two orthogonal sequences of burst signals, to be modulated by the O-QPSK system, has a preamble field set in a prescribed bit pattern. In a Costas loop for recovering carriers by the QPSK system, a 1/2 symbol delay circuit (14) makes the phases of burst signals inputted to two orthogonal channels identical to each other. A phase comparator (19) for the bit timing recovery field adds with an adder (193) a detected carrier value detected by an arc tangent calculating circuit (191) and a value resulting from the delaying of the detected carrier value with a one-symbol delay circuit (192), and supplies the added detected carrier value. A switching circuit (22) switches and supplies the outputs of phase comparators (18 to 20), and enters the output into a loop filter (23).

Abstract: Methods and apparatus for monitoring and controlling the operation of a refrigeration unit (20) in a manner which eliminates the need for circuit breakers and fuses in control circuits which are instrumental in selecting and changing the operational mode of the refrigeration unit. When a need to change to a different operating mode is detected, a controller (96) energizes a control device associated with the different operating mode and quickly determines if the current draw is within an acceptable range. If the current draw is within an acceptable range or window, the controller initiates the requested different operating mode. If the current draw is not within the acceptable range, the controller generates an appropriate alarm and different courses of action are decided upon which depend upon whether the current draw is above or below the limits of the acceptable range, the nature of the requested operating mode, and the desired temperature of a space conditioned by the refrigeration unit.

Abstract: A system and method ensure transmission of data elements between computers at a preselected quality of service. A computer in a layered reference model communication network requests a preselected quality of service for selected transmissions. An existing session is employed whereby transmissions having a variety of preselected of service guarantees are multiplexed onto the existing session. Data elements having the preselected qualities of service are transferred from service channels of another such layer. In one embodiment a system and method are provided for use between layer N+1 and layer N, wherein elements from two or more service channels from N+1 are transferred to one or more service channels in layer N such that a preselected quality of service is provided for the elements being transferred. Elements from a service channel having a higher priority, deadline, or period are transferred from the layer N=1 service channel to the layer N service channel before elements from a service channel having a lower priority, deadline, or period. In yet another embodiment, the number of elements are constrained whereby no more than a fixed number of such elements will receive service in a layer N service channel at a given point in time.

Abstract: A method of performing handover of a call associated with a mobile station (P2) in one cell (3) but moving towards another cell (2), which includes making a first attempt, using for example a MUX1 SNIFF procedure, on the channel allocated to the mobile station for that call, and if that attempt fails allocating the mobile station a different channel in the one cell (3) and making a second attempt. This different channel allocation (intracell handover) is performed even if there are no better signal characteristics achieved as a result. This procedure makes it more likely to be possible to achieve handover when a second mobile station (P1) associated with an adjacent cell (1) and operating on the same channel as the first mobile station (P2) is also within range of the basestation (5) of the other cell (2).

Abstract: A controllable current source in an AKB circuit (70) applies a measurement current (Im) to a kinescope driver amplifier (50) during selected lines of the vertical interval of a video input signal to induce a beam current in a kinescope (40) coupled to the driver amplifier. A comparison circuit (100, 102,104) compares samples (S5) of the beam current (IK) obtained during the selected lines with a reference signal (Vr) and applies a correction current (Iq) to the driver amplifier (50) for regulating a parameter (e.g., black level) of images displayed by the kinescope (40). A signal source (HB, R2), coupled to the measurement current source (82,90,92,96), inhibits production of the measurement current (Im) during retrace portions of the selected lines and enables production of the measurement current (Im) during trace portions of the selected lines. Advantageously, the signal source provides suppression of visual artifacts due to AKB operation when using direct view or projection kinescopes of a type in which pincushion correction is not applied during line retrace intervals.

Abstract: An antenna array has three horizontal coils (A,B,C) with equal spacings s, and two coplanar vertical coils (D,E) with a horizontal spacing 2f. When it is located over one or more current-bearing buried conductors, signal currents ( A , B , C , D , E ) are induced in the coils. The difference value  D - E  is measured and compared with a value " D - E " calculated from the equations:           "(D-E)" = 2f/ ("d"       2           +f       2       )                 "d" = 2s (       B     ̲     -       C     ̲     )/[(       A     ̲     -       B     ̲     ) - (       B     ̲     -       C     ̲     )].           
 Identity indicates that the signal source is a single conductor. A larger calculated value indicates plural sources with mainly vertical separation. A small calculated value indicates plural sources with mainly horizontal separation.

Abstract: A plurality of digital signal processors (DSP1-DSP4) are provided in parallel relation to each other, and a series of operations for desired sound signal synthesis or processing is divided into a plurality of operation groups to be allocated to the signal processors. First and second buses (PBUS, DBUS) are connected to each of the signal processors so that parameters necessary for the operations are distributively supplied to the signal processors via the first bus (PBUS) and the operation result of each of the signal processors is transferred to another digital signal processor or an output port via the second bus (DBUS). One digital signal processor receives the output data from another digital signal processor via the second bus so as to perform a predetermined operation using the received data. The desired sound signal processing is thus executed by combinations of the operations performed by such signal processors. Where sound signal processing is executed in a plurality of channels on a time-divisional basis, the time-divisional channel timing of each digital signal processor is set independently of that of other digital signal processors. By setting synchronized tone generation designating data for each channel, synchronized tone generation is controllably performed in selected channels.

Abstract: A lighting apparatus 1 has a convex lens 11 arranged so that its optical axis is at an angle θ with respect to the normal of an observation portion 3a (e.g., a semiconductor substrate or the like), with a camera 5 arranged in the path of the reflected light rays. When a light-emitting portion 13 is arranged along the optical axis of the lens 11, a bright field illumination takes place. If a knob 29 is turned, the light-emitting portion 13 moves along a ball screw 25, thereby changing the illumination from a bright field illumination to a dark field illumination. When a knob 37 is turned, the light exiting the lens 11 will diverge if the light-emitting portion 13 is moved close to the lens 11, converge if the light-emitting portion 13 is moved far away from the lens 11, and be parallel if the light-emitting portion 13 is positioned at the focal point of the lens 11. By changing the position of the light-emitting portion 13 in this way, it is possible to change the illuminating angle and the illuminating angle distribution, and by adjusting the position of the light-emitting portion 13 in accordance with the optical characteristics of the object 3, it is possible to obtain a high contrast image. It is also possible for these adjustments to be carried out automatically by using an actuator, microcomputer or the like.
