A planar display apparatus with a fluorescent screen formed on the inner surface of a front panel in a planar tube body. An electron gun is disposed at a position deviated in a vertical scanning direction from a region opposite the fluorescent screen, and a vertical deflecting electrode composed of a plurality of parallel electrodes is disposed at an opposite portion relative to the fluorescent screen on the side of a back panel opposed to the front panel of the planar tube body. In a space between the vertical deflecting electrode and the fluorescent screen, there is disposed an electrode structure having at least an electron lens scanning electrode composed of a plurality of parallel electrodes, a splitting electrode for splitting an electron beam from the electron gun into a plurality of beams, a modulating electrode, and horizontal deflection electrodes.

Residual extracellular protease activities of a Bacillus subtilis strain can be further reduced by introducing a gene for the stimulation of extracellular protease levels into the genomic DNA of the strain.The resultant strain whose extracellular protease activities are further reduced is transformed with a recombinant plasmid for secretion of a desired protein and the desired protein can be efficiently produced and accumulated in the culture medium in a large amount. The accumulated desired protein can be easily recovered from the culture medium.For example, the accumulation level of human growth hormone secreted by a B. subtilis MT-430 strain carrying recombinant DNA phGH427 for the expression and secretion of human growth hormone can be increased five to tenfold as a result of the above treatment for reduction of the residual extracellular protease activities of the extracellular protease-activity-deficient strain.

摘要:
In a work machine, as a regeneration need determining unit determines that a collecting unit needs to be regenerated, a load control unit causes an increase in load on an engine by controlling a pressure accumulating unit so as to accumulate pressure oil attributable to an output of the engine in the pressure accumulating unit as pressure energy from the hydraulic pump; and once the pressure energy is accumulated to a level matching a pressure accumulation upper limit at the pressure accumulating unit, the load control unit causes the increase in the load on the engine by controlling a power storage unit so as to store electric energy of power generated at a generator attributable to the output of the engine in the power storage unit.

A source driver for a liquid crystal display (LCD) panel in which during a first predetermined period immediately after polarity of a voltage according to image data is inverted, each column terminal of the LCD panel is shorted to a common line through an output terminal and a second switch element, a first output amplifying portion is set to a high impedance state, and an output signal of a second output amplifying portion is fed back to a differential amplifying portion through a third switch element. During a period after the first predetermined period and before inversion of polarity of a voltage according to the image data, an output signal of the first output amplifying portion is supplied to the output terminal without passing though a switch element, and is fed back to the differential amplifying portion through a fourth switch element. The output signal of the second output amplifying portion is fed back to the differential amplifying portion through the first and fourth switch elements.
