Title: Image pickup apparatus with gain controlled output amplifier
Inventor: SONEDA MITSUO
IPC: H04N5/243
Filed: 1982-05-19
Granted: 1985-04-02
Abstract: ABSTRACT OF THE DISCLOSURE           Solid-state image pickup apparatus, such as an MOS imager, has a two-dimensional array of picture element units each formed of a photo sensitive element and a gating element.  The picture unit elements discharge a signal charge onto vertical and horizontal transmitting lines in response to vertical and horizontal scanning pulses.  Then, a resulting signal current is used to develop an output video signal.  In order to give the output video signal a good S/N ratio, a gain-controlled current amplifier is employed.  In several embodiments, the gain-controlled amplifier includes first through fourth transistors with the base-emitter junctions of the first and second transistors and of the third and fourth transistors connected in series, with a constant current source coupled to the first transistor, controlled current sources connected to the second and third transistors, and a load device coupled to the fourth transistor.  In other embodiments, the gain controlled amplifier is formed of first, second, and third current mirror circuits connected in a balanced-current arrangement.  Electrically variable resistances, e.g., MOS transistors, are coupled to the output transistors of the first and second current mirror circuits to control the current gain.

Abstract: ABSTRACT: "Code generator."     A code generator is provided which produces a transmission code in response to a serial binary data stream applied to its input (1). The transmission code is similar to that known as WAL2 but whereas WAL2 involves a double frequency component when the binary data changes from "1" to "0" or vice versa the transmission code pro-duced by the code generator holds the output signal con-stant at a level intermediate those corresponding to the binary "1" and "0". This reduces the high frequency con-tent of the transmitted signal and consequently reduces crosstalk between channels.        The code generator comprises a first current source (I1) which is connected to a summing network (R1) through a first switch (T1, T3), a second current source (I2) which is connected to the summing network (R1) through a second switch (T2, T4) and a control circuit (1-14) which produces signals on lines (13, 14) to selectively operate the first and second switches.

Abstract: IMPROVED COMPENSATED LOAD CELL                           ABSTRACT This invention relates to new and improved single beam load cells which are compensated for both longitudinal and lateral displacement of the load; to new and improved scale arrangements incorporating such load cells; and to methods of compensating such single beam load cells.  In one embodiment of the invention strain gages are attached to only one side of the beam and the beam is honed or filed to compensate for both longitudinal and lateral displacement of the load.  In another embodiment of the invention strain gages are placed on both sides of the single beam and the strain gages are placed on the beam at a slight angle from the longitudinal axis of the beam.  In this embodiment the beam may be honed to compensate for both lateral and longitudinal displacement of the load. In addition, with the strain gages displaced at a small angle with respect to the longitudinal axis of the beam, the load cell may be compensated for both longitudinal and transverse displacement of the load by placing resistors in parallel with two or more of the strain gages.        The single beam is mounted or supported at one end thereof and the other end supports the platter or platform of the scale arrangement.  The platter or platform mounting arrangements may be arranged to provide moment insensitive arrangements, and in one exemplary embodiment the platform or platter is supported by one end of the single beam load cell at or near an edge thereof.

Abstract: ABSTRACT     A completely cooled fast fluidized bed boiler com-prises a reactor (4) having a bottom section (3), an integrated primary non-centrifugal mechanical particle separator (5), a gas pass (7) containing convective heat exchangers (10), and means (6,8,9) for controllably recirculating separated particles into the reactor bottom section (3). Reactor (4), separator (5) and gas pass (7) are built as an integrated unit within one and the same cooling system. The boiler is controlled by maintaining the bed temperature substantially constant or within a relatively narrow temperature interval by regulating the recirculation rate dependent on boiler load. For regu-lating the recirculation rate a non-mechnical valve, pre-ferably a so-called L-valve (8), is used.     (Fig. 1)

Abstract: ABSTRACT OF THE DISCLOSURE     Although TTL-PROMs possess many advantages over their CMOS-PROM counterparts, their use in controlling on-off operations of indicators such as flashing navigational lights has been limited when battery power is required due to the high power consumption of such TTL-PROMs. Accordingly, a programmable control circuit is provided which includes a TTL-PROM together with a plurality of lower power consumption CMOS units and which minimizes the power consumption of the TTL-PROM. The TTL-PROM has a plurality of memory cells programmed with a plurality of code words. A CMOS addressing means is coupled to this PROM to generate address words to address the memory cells. This addressing serves to activate the PROM to output the appropriate code words in a parallel format. A          CMOS parallel-series converter is coupled to receive the parallel format code words from the PROM and convert these to a serial code output signal. This serial code output signal is then used to drive the indicator device. In particular, in order to reduce the power consumption of the overall system, an intermittent power-up circuit is coupled to the PROM for powering the PROM on only during periods when it is necessary to permit addressing the PROM and transferring code words from the PROM to the parallel-series converter.

Abstract: ABSTRACT         A progressive cavity pump of the type having a stator member and a rotor member disposed within a cavity in the stator member and being rotated while being permitted to orbit about a central axis of the stator in operation, one of the members being formed of resilient material and the other of rigid material.  The rotor is of helical formation having a constant circular transverse cross-section and defining a single-start thread of a preselected pitch and direction, and the cavity of the stator is in the form of a two start thread of the same direction as the rotor and twice the pitch, the cavity in transverse cross-section has an outline defined by a pair of spaced semi-circular concave ends and a pair of sides joining the semi-circular ends.          The semi-circular ends have a diameter slightly less than the diameter of the cross-section of the rotor for establishing an interference fit between the rigid and resilient members.          The pair of sides have an inward curvature so that the distance between the pair of sides is slightly less than the diameter of the circular ends whereby sealing areas of increased interference  are provided between the members.          Unlike known progressive cavity pumps, a high pressure output is possible without making the pump inefficient or of a prohibitive length.
