    摘要： A method of producing pyromellitic dianhydride. The method includes a step of heating a crude pyromellitic acid in the absence of acetic anhydride to convert a part of pyromellitic acid to pyromellitic anhydride, and a subsequent step of heating the resultant mixture in the presence of acetic anhydride to complete the anhydrization of pyromellitic acid. The pyromellitic dianhydride by the method contains little pyromellitic monoanhydride and other monoanhydrides derived from impurities and is less discolored. The pyromellitic dianhydride has particle properties not causing plugging, etc. during its transportation, storage and use.

    摘要： A fluid machine for a gas compression refrigerating system comprises a first and a second working for performing a pump mode operation, in which working fluid of low pressure is sucked into and compressed by the working chambers. The fluid machine further comprises valve mechanism for selectively forming a motor mode passage in combination with a fluid passage change-over device, so that super heated working fluid of high pressure is introduced into at least one of the working chambers to perform a motor mode operation, in which the high pressure working fluid is expanded in the working chamber to obtain mechanical energy. The fluid machine according to the invention, therefore, performs the pump mode operation at one of the working chambers and at the same time the motor mode operation at the other working chamber.

    摘要： A plasma processing apparatus includes an upper matching unit 44 which is a variable matching unit whose impedance can be varied, and a main controller 100. The upper matching unit 44 includes a controller 104 for variably controlling the impedance positions of a variable reactance element of a matching circuit 102, a RF sensor for measuring a load impedance including the matching circuit 102, and a VPP measuring circuit 112 for measuring a peak value (peak-to-peak value) of a radio frequency voltage in a waveguide line at the output side of the upper matching unit 44. The main controller 100 executes and controls an autorunning of the matching units 44, 88 for optimizing an off preset of the impedance positions thereof. The plasma can be readily get ignited without requiring to set or change special processing conditions while influencing none of the processes.

    摘要： A connecting device is formed by an internal thread and an external thread that is screwed into the internal thread and is integrally molded from synthetic resin. A protruding portion that interferes with a thread ridge of the internal thread is formed integrally with a thread bottom side of the external thread. The protruding portion is provided so that it raise a thread bottom portion in a portion of an area in the circumferential direction of the external thread, and when the two threads are screwed together, the protruding portion is shaved off or is elastically deformed by the thread ridge of the internal thread. Loosening can be avoided without intentional exterior force being applied, and suitable tightening torque can be generated consistently.
