Patent EP-0317236-A2 (EP)
Inventor: LARSEN RAYMOND S
IPC: G11C27/02
Filed: 1988-11-14
Abstract: The system comprises an analog integrated circuit using integrated field effect transistor technology comprising a plurality of sampling and storage cells (20). To achieve the high speed performance required, a two-stage sampling cell design is used. The first stage (22) incorporates a very small capacitor (C1) coupled to the input signal through a high speed gate (Q1, Q3). This gate, which is opened only by the simultaneous occurrence of row and column signals, causes their first capacitor (C1) to capture at very high speed a sample of the analog signal under study. When all the first capture sections (22) of the cells have captured on their capacitors (C1) a sample of the analog signal, a transfer gate (Q7) is briefly opened to transfer the captured and buffered sample values to a second or storage section (24) of the cells (20). This storage section (24) incorporates a capacitor (C2) substantially larger than the capacitor (C1) in the capture section (22), and capable of storing the signal for a considerably longer time.

Abstract: A cylindrical ring (20) and a character (22) having a number of extending parts (24, 26) that are circumscribed by a circle having a diameter equal to the inside diameter of the ring are readily combinable by a child to make a rotating toy. Insertion and removal of the character from the inside of the ring are facilitated by making the ring and/or character of a deformable material. The combined ring and character may be placed in a vehicle (34) in contact with the vehicle wheels (40) so that as the vehicle is moved along a playing surface, the wheels rotate the combined ring and character. Part of the vehicle body (42) is hinged for closing an opening through which the combined ring and character are inserted. Above the ring is a transparent dome in which a ball is positioned in contact with the ring so that as the combined ring and character rotate, the ball rotates within the dome. Other accessories provide rotatable surfaces which engage the outer curved surface of the cylindrical ring to rotate the combined ring and character. Yet another accessory provides surfaces on which the combined ring and character roll, under the force of gravity, and produce a bell ringing action.

Abstract: The present invention discloses a magneto-optical memory apparatus comprising: 
an optical head; 
a magneto-optical recording medium relatively mova­ble with respect to the optical head, into which recording marks, each having two ends, are recorded as information; 
the optical head being arranged such that,
     (i) at the time of recording into the magneto-opti­cal recording medium, the recording marks are recorded such that the ends of each recording mark correspond to a second code of digital information composed of two dif­ferent types of codes,   (ii) at the time of reproduction, a light beam having a condensing spot is projected to the magneto-opti­cal recording medium and, when a reproduction light con­taining reproduction information is entered to the optical head from the magneto-optical recording medium, a repro­duction signal is supplied, and   (iii) when the light beam is projected to a record­ing mark, an information pulse corresponding to the second code is generated in the reproduction signal, only when the reproduction light from the recording mark interferes with the reproduction light from the non-marking part; and      a signal detector circuit for detecting the informa­tion pulse in the reproduction signal obtained from the optical head and for converting the reproduction signal into a digital reproduction signal.
     Each of the recording marks contains a number of information to enhance the recording density of the mag­neto-optical recording medium, thereby to increase the recording capacity. Further, the recording marks may be made in a large size and in a suitable shape. This facili­tates the transfer of the recording marks made by plastic forming and the like. Futher, the optical system may be simplified in arrangement. 
     The optical memory apparatus in accordance with the present invention includes the arrangement above-mentioned and is so arranged as to reproduce the recorded informa­tion by diffraction of the lights reflected from the opti­cal information recording medium having recording marks formed therein.

Abstract: A concentrator having two mutually independent control devices scanning all relevant subscriber stations and having two channel systems allocated to them for connection to a higher-lever exchange. Both control devices call up switching data and temporarily store these, but only a first one of them also calls up operating status data and these can only be temporarily stored by this control device. The latter makes available to these data a central processor which interrogates the control devices at time intervals. The first control device continuously supplies the operating status data temporarily stored in it to the second control device. If the processor detects a disturbance of a general type or of the relevant channel system during the interrogating, occurring at time intervals, of the first control device for switching data or operating status data, it immediately selects the second control device and receives via it the operating status data, supplied without temporary storage, which are continuously output as a precautionary measure from the first control device to the second control device and are passed via the second control device to the processor without temporary storage. <IMAGE>
