摘要:
A process and an apparatus for producing an aromatic carboxylic acid by a liquid phase oxidation of an alkyl aromatic compound with a molecular oxygen-containing gas in the presence of an oxidation catalyst in a reaction solvent in an oxidation reactor, which process can afford to suppress the amount of non-condensing gas lost in accompaniment with the withdrawn slurry of the formed aromatic carboxylic acid crystals from the oxidation reactor to thereby increase the utilization efficiency of the molecular oxygen-containing gas, wherein a deflector 10 is arranged on the inner surface of the reactor wall at a portion downstream from the opening 9 for the slurry withdrawal line 8 in the flow path of the stirring stream 11 of the reaction liquor and the oxidation is conducted while stirring the reaction liquor by a stirrer 3 and while withdrawing the resulting slurry containing the formed aromatic carboxylic acid crystals from the reactor, by feeding the alkyl aromatic compound together with the reaction solvent and with the catalyst to the reactor via a raw material feed line 6 while supplying the molecular oxygen-containing gas thereto via a gas supply line 7, whereby the amount of the non-condensing gas entrained in the withdrawn slurry from the reactor is suppressed.

An inverter circuit is connected in series to an AC power supply, and at the subsequent stage, a smoothing capacitor is connected via a converter circuit including semiconductor switching devices. A control circuit controls the converter circuit by providing a short-circuit period for bypassing the smoothing capacitor in each cycle, and controls the inverter circuit to improve the power factor of the AC power supply by using a current instruction such that the voltage of the smoothing capacitor becomes a target voltage. When the voltage of a DC voltage source of the inverter circuit has exceeded a predetermined upper limit, the control circuit increases the current instruction to control the inverter circuit, thereby increasing the discharge amount of the DC voltage source. Thus, even if the voltage variation of the DC voltage source of the inverter circuit increases, it is possible to stably continue the control.

A power conversion apparatus includes a high-power-factor converter section converting an AC voltage to a DC voltage, a smoothing capacitor, a DC/DC converter section, and a control circuit. The control circuit controls the high-power-factor converter section such that the power factor of AC is controlled and a DC voltage follows a target value, and performs duty control for semiconductor switching devices such that a DC voltage from the DC/DC converter section to a load follows an instruction value. In accordance with the DC voltage, the control circuit adjusts the DC voltage target value of the high-power-factor converter section such that the duty ratio of the semiconductor switching devices approaches a set value, thereby optimizing the duty ratio of the semiconductor switching devices and reducing power loss.

A semiconductor display device is formed including an interlayer insulating. Specifically, a TFT is formed and then a nitrogen-containing inorganic insulating film that transmits less moisture compared to organic resin film is formed so as to cover the TFT. Next, organic resin including photosensitive acrylic resin is applied and an opening is formed by partially exposing the organic resin film to light. The organic resin film where the opening is formed, is then covered with a nitrogen-containing inorganic insulating film which transmits less moisture than organic resin film does. Thereafter, the gate insulating film and the two layers of the nitrogen-containing inorganic insulating films are partially etched away in the opening of the organic resin film to expose the active layer of the TFT.
