    • A process for producing a modified phenolic resin, comprising heating a heavy oil or pitch of given average molecular weight and, per mol, calculated from the average molecular weight, of the heavy oil or pitch; 0.3 to 25 mol, in terms of formaldehyde, a formaldehyde compound and 0.5 to 50 mol of a phenol of the formula (I) (wherein R1 represents a linear or branched unsaturated hydrocarbon group having 1 to 2 unsaturated bonds and having 2 to 10 carbon atoms, p is 1 or 2, X represents an alkyl group having 1 to 5 carbon atoms, and q is 0 or 1) under stirring in the presence of an acid catalyst to thereby effect a polycondensation. The modified phenolic resin obtained by this process, as compared with the conventional modified phenolic resin produced from a heavy oil or pitch as a feedstock, has an extremely low softening point so as to be flowable at about room temperature and has also a low melt viscosity, thereby ensuring very excellent moldability. Further, in combination with an epoxy resin, the modified phenolic resin can be formed into a molded article which is excellent in not only heat resistance, moisture resistance, corrosion resistance and adhesive force but also mechanical properties such as dimensional stability and strength.
    • 一种制备改性酚醛树脂的方法,包括加热重油或沥青的给定平均分子量,每摩尔由重油或沥青的平均分子量计算; 0.3〜25摩尔,以甲醛计,甲醛化合物和0.5〜50摩尔式(I)的苯酚(其中,R1表示具有1〜2个不饱和键且具有2〜10个碳原子的直链或支链的不饱和烃基 原子,p为1或2,X表示碳原子数1〜5的烷基,q为0或1)在酸催化剂的存在下搅拌,进行缩聚。 通过该方法获得的改性酚醛树脂与由重油或沥青作为原料生产的常规改性酚醛树脂相比具有极低的软化点,以便可在约室温下流动并且还具有低熔体粘度 ,从而确保非常优异的成型性。 此外,与环氧树脂组合,可以将改性酚醛树脂形成为不仅具有耐热性,耐湿性,耐腐蚀性和粘合力优异的机械性能如尺寸稳定性和强度的成型品。

    • A color thermal printer has three thermal heads disposed along a transport path of a thermosensitive recording sheet. Each of the thermal heads are supported in movable fashion between an advanced position where the thermal heads are pressed against the recording sheet, and a retracted position away from the recording sheet. An advancing period is predetermined to precede a time point when each thermal head starts being driven. The thermal heads are serially moved to the advanced position, from the retracted position slowly during the predetermined advancing period, gradually to raise the pressing force of the thermal heads to the recording sheet. A full-color image is thermally recorded to the recording sheet by the thermal heads in the advanced position while the recording sheet is transported in one direction.
    • 彩色热敏打印机具有沿着热敏记录纸的输送路径设置的三个热敏头。 每个热敏头在可移动的方式被支撑在热敏头压靠在记录纸上的高级位置和离开记录纸的缩回位置之间。 前进时间预先设定为在每个热敏头开始被驱动的时间点之前。 热敏头在预定的前进时段内缓慢地从缩回位置连续地移动到前进位置,逐渐地将热敏头的压力提高到记录纸。 当记录纸沿一个方向传送时,全色图像通过热敏头在高级位置被热记录到记录纸上。

    • In an optical transmitting and receiving apparatus. an light transmitting and receiving unit includes a light emitting element, a light transmitting lens, a light receiving lens, and a photosensitive element. The light emitting element outputs light. The light outputted from the light emitting element passes through the light transmitting lens before leaving the light transmitting and receiving unit as outgoing light. The light receiving lens concentrates incoming light on the photosensitive element. A first support member is operative for supporting the light transmitting and receiving unit, and for allowing the light transmitting and receiving unit to rotate about a first axis. A first rotary mechanism connected to the light transmitting and receiving unit and the first support member is operative for rotating the light transmitting and receiving unit about the first axis. A second support member is operative for supporting the light transmitting and receiving unit on a cantilever basis, and for allowing the light transmitting and receiving unit to rotate about a second axis perpendicular to the first axis. A second rotary mechanism connected to the light transmitting and receiving unit and the second support member is operative for rotating the light transmitting and receiving unit about the second axis.
