    • Processes for producing a polyoxymethylene copolymer includes forming a crude polyoxymethylene copolymer by subjecting a reaction system containing trioxane, a cyclic ether or cyclic formal comonomer, and a catalyst (e.g., boron trifluoride or a coordination compound thereof) to copolymerization reaction conditions. During copolymerization, both the total content of impurities and catalyst in the copolymerization reaction system are adjusted. In this regard, the impurities content (i.e., those compounds which form unstable end groups in the polyoxymethylene copolymer and/or those compounds having a chain-terminating or chain-transfer function) in the copolymerization reaction system is adjusted to 1.times.10.sup.-2 mole percent or less based on the total monomer amount, while the the content of the catalyst in the copolymerization reaction system to between 1.times.10.sup.-3 to 1.times.10.sup.-2 mole percent based on the total monomer amount. Immediately after copolymerization has been completed, the crude polyoxymethylene copolymer is quenched to a temperature of 45.degree. C. or less within 30 seconds after completion of copolymerization. Quenching of the crude polyoxymethylene copolymer is preferably simultaneously accompanied by deactivation of the catalyst by bringing the crude polyoxymethylene copolymer immediately following completion of copolymerization into contact with a cold liquid which contains a catalyst deactivator.
    • 用于制备聚甲醛共聚物的方法包括通过使含有三恶烷,环醚或环状形式共聚单体的反应体系和催化剂(例如三氟化硼或其配位化合物)进行共聚反应条件来形成粗聚甲醛共聚物。 在共聚过程中,调节共聚反应体系中杂质和催化剂的总含量。 在这方面,将共聚反应体系中的杂质含量(即,在聚甲醛共聚物中形成不稳定端基的那些化合物和/或具有链终止或链转移功能的那些化合物)调节至1×10 -2摩尔% 或更少,而共聚反应体系中催化剂的含量相对于总单体量为1×10 -3〜1×10 -2摩尔%。 共聚完成后立即将聚甲醛共聚物在共聚完成后30秒钟内淬火至45℃以下。 粗聚甲醛共聚物的淬火优选同时伴随着催化剂的失活,使粗聚甲醛共聚物在完成共聚后立即与含有催化剂失活剂的冷液接触。

    • A plurality of first and second sensor pixel circuits each sensing light during a designated sensing period and retaining the amount of sensed light otherwise are arranged in a pixel region. A backlight is turned on once for a predetermined time in one-frame period. A sensing period when the backlight is turned on and a sensing period when the backlight is turned off are set once, respectively, in the one-frame period. The first sensor pixel circuit is reset. The second sensor pixel circuit is reset. Read from sensor pixel circuits of two types is performed in parallel in a line sequential manner during a period other than the periods and. A difference circuit provided outside of the sensor pixel circuits is used for obtaining a difference between an amount of light when the backlight is turned on and an amount of light when the backlight is turned off.
