Abstract: A radio receiver apparatus receives a transmission signal on the basis of a reference pattern put in the transmission signal at a predetermined timing and is composed of a receiving unit, a received data processing unit and a first and a second phase shift information detection unit. The receiving unit demodulates the transmission signal to output received data. The received data processing unit performs data processing the received data synchronized with the received data on the basis of the reference pattern formed of a predetermined bit pattern. The first phase shift information detection unit detects the first phase shift information of the received data corresponding to the data processing of the received data processing unit on the basis of the reference pattern. The second phase shift information detection unit generates the state where phase of the received data is shifted so as to detect the second phase shift information of the received data corresponding to the data processing of the data processing unit. The radio receiver apparatus corrects phase shift of the received data based on the compared result of output signal from the first phase shift detection unit and the second phase shift detection unit.

Abstract: In fuel gasification, particles (5) of e.g. coal and an oxidant (6) are supplied to a reactor (1), where the coal particles (5) are gasified. The gas (7) thus produced may contain molten slag entrained therein and such slag could subsequently solidify and affect other components of the coal gasification apparatus. Therefore a molten slag cooling heat exchanger (16) is positioned directly above the reactor (1) and this cools the gas (7) so as to cause any molten slag therein to solidify. Hence, such molten slag does not reach an evaporator (23) above the molten slag cooling heat exchanger (16), so that the efficiency of the evaporator (23) will be maintained. However, solidified molten slag may build up on heat exchange tubes of the molten slag cooling heat exchanger (16). Therefore, the rate of coolant (18) supplied to the molten slag cooling heat exchanger is varied, to cause expansion and contraction which causes solidified slag to be dislodged. Hence the efficiency of the molten slag cooling heat exchanger (16) does not deteriorate. Cleaning gas (25) and coal particles (28) may be jetted onto the evaporator (23) to dislodge ash or soot therefrom.

Abstract: An apparatus for dosing a liquid medicine has a balloon (1), a housing (3) and a delivery assembly 'b'. The balloon receives and discharges a liquid medicine under pressure. The housing enclosing the balloon has an opening communicating with the assembly 'b' in which a flow regulator (10) is installed. The balloon (1) is composed of flat and expansible sheets secured to both side rims of a short cylindrical frame (2). The flat sheets constituting the balloon are of an even thickness over their whole area, even after being inflated with the medicine, so that the pressure as well as the flow rate of the medicine effluent from the balloon will scarcely vary at the mouth over the course of time. Thus, the liquid medicine is dosed to a patient at a constant flow rate through the regulator.

Abstract: In order to determine the presence of the discs 12, each of the discs is pushed out for a predetermined distance from the inner side portal of a stocker by a rotation lever. When the disc is pushed out, the transmission of light from a disc presence detection sensor is obstructed, so that the presence of the discs is detected. When the disc tray is opened, the disc is prevented from accidentally falling due to the disc stopper of the carriage and with the regulation bar of the carriage. When two discs are placed on the disc tray, the lower disc is drawn out between side regulators, and the upper disc is not drawn out due to contact with the disc transfer prevention parts. When a LED is lighted, the light is reflected on each of the light reflectors formed on the display plate next to the discs. With such light, the position of discs corresponding to each of the light reflectors can be accurately confirmed.

Abstract: In order to share out central resources fairly between low-speed and high-speed input/output ports 20-1, 20-2 of an input/output control unit, an activation time between a time point when an end status associated with the end of a transfer is sent and a time point when an activation request is received is measured and stored in a memory 48. When the high-speed port receives an activation request from a high-speed channel, the activation time in the memory measured with respect to the low-speed port is read out and during this activation time an input/output request for the low-speed port is preferentially accepted. To provide the activation time for the low-speed port the minimum time, average time and maximum time are obtained from the result of the measurement. Any of these three times can be selected as the activation time in order substantially to equalize the busy ratios of the high-speed and low-speed ports. Allocation can also be made in alternative ways, for instance by reference to the number of requests which meet with a busy signal.

Abstract: A deflection waveform correction signal generator comprises a parabolic shaped signal generator (U1, Q100) and first (Q2, C2) and second sawtooth (600) shaped waveform generators. The first horizontal frequency sawtooth shaped waveform is generated by a clipped retrace pulse. The first sawtooth generator (Q2, C2) has an output coupled to an integrating circuit (U1, Q100) for generating a parabolic shaped signal (P). The sawtooth generator (Q2, C2) and sawtooth waveform integrator (Q1, Q100) are reset at a horizontal rate by reset pulses of differing duration. The different duration of reset pulses results in the parabolic signal (P) having regions of non-parabolic shape. A control loop (400) is coupled to the integrator and measures and maintains a pulse (PC) duration generated responsive to the parabolic signal (P). A control current (IT) is generated responsive to the pulse (PC) duration and is coupled to the integrator (U1) input to cause the parabolic shaped signal (P) to be generated at a predetermined time interval. The pulse (PC) is also coupled to the second sawtooth generator (600) which generates a horizontal rate signal (HSAW) for skew and trapezium correction. A multiplying circuit (U2) generates a trapezoidal correction signal by multiplication of the second sawtooth signal (HSAW) and a vertical rate sawtooth signal (VSAW).

Abstract: The on-chip endurance test (Autocycle) and the parametric characterization test (Auto VccMax/Min) of this invention save test time and hardware by performance automatically on the memory chip upon transmittal of a single command (CONTROL CODE) to the chip from the tester. The automated test procedures of this invention run faster because the on-chip tester requires fewer externally issued commands (CONTROL CODEs) and requires fewer external status checks. The procedures of this invention permit the external tester to have a smaller number of input/output pins (CONTROL), decreasing the cost of the external test hardware. Specifically, the endurance test (Autocycle), automatically cycles the memory chip through any combination of programming, erasing, and/or compaction operations until either a failure has been detected or the required number of the test cycles has been completed. The parametric characterization test (AutoVccMax/Min) determines automatically the maximum supply voltage and/or the minimum supply voltage for data operation of the memory chip. The endurance test (Autocycle) uses a microsequencer (MC) and an on-chip built-in-logic-block-observation (BILBO) register to check information in a control-read-only memory (CROM). Output data from the control-read-only memory is latched in a BILBO register enhanced for use as a counter for large count. During the endurance test (Autocycle), the microsequencer (MC), using enhanced counter, monitors the number of on-chip controlled endurance test cycles. During the parametric characterization test (AutoVccMax/Min), an on-chip digital-analog converter (DAC) causes stepped changes in the supply voltage (Vcc) furnished to both the data cells (10) and the reference cells (10) of the memory.
