Patent EP-0469862-A2 (EP)
Inventor: NISHIMORI MIKI
IPC: G11C11/409
Filed: 1991-07-30
Abstract: A data amplifying system in a semiconductor memory includes a current mirror circuit (2) for receiving, via a data bus (DB,            DB     ¯           ), an input signal (In,            IN     ¯           ) corresponding to data read out from a memory cell (1a, 1b) via a pair of bit lines (BL,            BL     ¯           ) and for amplifying the input signal. The current mirror circuit operates on the basis of a power supply voltage (Vcc). An amplitude limit circuit (3) receives an operation voltage (Vcc/2) and limits the amplitude of the input signal on the data bus to a predetermined potential range on the basis of the operation voltage. A bit line reset potential generator (5) generates a bit line reset potential (Vcc/2) and applies the bit line reset potential to the bit lines and the amplitude limit circuit. The bit line reset voltage is lower than the power supply line and serves as the operation voltage applied to the amplitude limit circuit.

Abstract: Optical disk drive apparatus which is operable in a reading mode and in a writing mode comprises a laser driver (26) for varying the power of a laser beam. Control means (16,18,20,22,24,44,40,42) is coupled to the laser driver (26) to maintain the power of the laser beam at a constant value when the apparatus is operating in the reading mode, the constant value being determined by a predetermined reference signal, and to vary the power of a laser beam in response to an input data signal when the apparatus is operating in the writing mode. In the writing mode, the control means (16,18,20,22,24,44,40,42) varies the power of the laser beam as a function of the input data signal and the reference signal. Because the power of the laser beam in the writing mode can be referenced to the power of the laser beam in the reading mode, the laser power in each one of a group of similar disk drives can be automatically and consistently optimised even if the efficiency of the laser emitter in each drive is different.

Abstract: A method of controlling an injection molding machine by use of nozzle resin pressures in which resin is directly controlled to thereby enable highly accurate control, and a conventional mold can be utilized as it is. 
     After metering a dose of resin, a resin pressure at the upstream side of a nozzle switching valve (12) is detected while the nozzle switching valve (12) is kept closed, and a pre-load is applied on the resin by controlling an injection cylinder (19). Subsequently, the nozzle switching valve (12) is opened, and injection of the resin is performed, then applying a dwell pressure on the resin in the mold. During the injection and dwell pressure application steps, a resin pressure at the downstream side of the nozzle switching valve (12) is detected, and the injection cylinder (19) and the nozzle switching valve (12) are controlled. In these steps, the resin to be filled is directly controlled, and therefore, the control can be carried out highly accurately. After the dwell pressure application step, the nozzle switching valve (12) is closed. Then, the resin pressure at the upstream side of the nozzle switching valve (12) is detected, and a back pressure is applied on the resin at the front end of a screw feeder (2) by controlling the injection cylinder (19).

Abstract: A charge-coupled imaging device (Fig. 3) is thinned to allow for backside illumination. The device is further enhanced using ion implantation techniques to establish an electrical field (44) at the back surface, which functions to drive free electrons to potential wells generated beneath a gate structure (40) on the front surface. The device structure allows for both front side and backside illumination and is useful as a imaging device in applications where it is necessary to combine images from two different optical sources. The imaging device is particularly useful in terrestrial guidance systems (Fig. 5) where the imaging device is used to detect guide stars from a large guide star field. In such systems, the imaging device must be translated within an X-Y plane in order to cover the entire guide star field. In order to accurately know the position of the imaging device, optical fiducial marks are imaged onto a side of the imaging device opposite the side receiving the guide star photons. Using the two-sided imaging device allows for the elimination of optical elements necessary for combining the optical signals, particular the use of beam splitters.

Abstract: Processing (such as recording and/or reproducing) apparatus is capable of processing first and second digital signals with the same processing device, even when the two digital signals have differing first and second data configurations, the first data configuration containing a greater amount of data than the second data configuration. Predetermined data is added (23) to the second digital signal so as to convert the second data configuration to the first data configuration. An error processor (4A), such as an error detection/correction generator or an error corrector, and capable of processing the first data configuration, selectively (21) receives either the first digital signal or the converted second digital signal, so as to carry out the same error processing operation on either one of the digital signals.

Abstract: A two stage accumulator is provided for updating coefficients. The accumulator is particularly useful in an adaptive equalizer. A first stage of the accumulator receives an error word and outputs sign and carry bits resulting from the addition of the error word and an N-bit LSB portion of a larger M-bit coefficient. A second stage is responsive to the sign and carry bits for updating the (M-N) MSB's of the M-bit coefficient. New error words are cyclically provided to the first stage during successive coefficient update cycles. The first stage can be implemented using an N-bit twos complement adder. The second stage can be implemented using an up/down counter. A leakage function is provided by causing the up/down counter to periodically skip over increment and decrement cycles.

Abstract: Holding means for a component in a friction welding operation consists of a hollow cassette which is open at one end. The component is inserted into the cassette and an aperture at the open end is shaped to frictionally engage a thickened portion of the component with a force greater than forces transmitted to the component during a friction welding operation. The component is pressed into the cassette to a predetermined depth so that a portion remains protruding and forms the weld interface. Material upset during the welding operation may be sheared by increasing the weld generating force to overcome the frictional holding force so the end face passes over the weld region.
