    • Each of a sliding bearing and a rotating and sliding member according to the present invention includes an irregularity portion on its inner peripheral surface. The irregularity portion comprises projections adapted to come into contact with a rotary shaft, and recesses which are provided, so that they cannot be brought into contact with the rotary shaft to define gaps or spaces between the bearing itself and the rotary shaft. The irregularity portion is integrally formed-on the inner peripheral surface of the sliding bearing to extend in a direction of rotation of the sliding bearing, in such a manner that the recess is disposed at a central portion of the inner peripheral surface, and the projections are disposed on opposite sides of the recess. By forming the sliding bearing and the rotating and sliding member in the above manner, disadvantages such as the accumulation of a heat and the wearing of the bearing due to an increase in rotational speed can be suppressed to maintain a high rotational accuracy over a long period and to prolong the life of a product.
    • 根据本发明的滑动轴承和旋转和滑动构件中的每一个在其内周面上包括不规则部分。 不规则部分包括适于与旋转轴接触的凸起和设置的凹部,使得它们不能与旋转轴接触以限定轴承本身和旋转轴之间的间隙或空间。 该不规则部分一体地形成在滑动轴承的内周面上,以使滑动轴承的旋转方向延伸,使得凹部设置在内周面的中心部分,并且突出部 设置在凹部的相对侧上。 通过以上述方式形成滑动轴承和旋转和滑动构件,可以抑制由于转速增加而导致的热累积和轴承磨损等缺点,从而能够长时间保持较高的旋转精度 并延长产品的使用寿命。

    • In order to improve the adhesion property of an electrical steel sheet with no film of inorganic mineral matter on its surface, especially with respect to a tension-imparting insulating film, anodic electrolysis in an aqueous solution of silicate is carried out before insulating film formation to form a silicic film excellent in adhesion property with respect to the insulating film in a thin and strongly attached condition on the steel sheet surface. By this, a tension-imparting insulating film can be formed on a grain-oriented electrical steel sheet with excellent adhesion property to reduce the iron loss of the oriented electrical steel sheet. Also in the case of an insulating film that is not of the tension-imparting type, enhancement of film heat resistance and improvement of insulating property by increasing a film thickness are possible.
    • 为了提高其表面没有无机矿物质膜的电工钢板的粘合性,特别是对于赋予张力的绝缘膜,在硅酸盐水溶液中进行阳极电解,在绝缘膜形成之前进行 在钢板表面上形成薄而坚固的条件下的绝缘膜的粘附性优异的硅膜。 由此,可以在具有优异的粘附性的方向性电磁钢板上形成张力赋予绝缘膜,以降低取向电工钢板的铁损。 另外,在不具有张力赋予型的绝缘膜的情况下,也可以通过增加膜厚来提高膜的耐热性和提高绝缘性。

    • The distance measuring device includes a light source (1), a light-receiving sensor (2), a timing controller (5), a distance calculator (6), and a delay controller (8). The timing controller (5) outputs a modulation signal and plural reference timing signals. The modulation signal is a square wave signal having high and low level periods appearing alternately. Each of the high and low level periods has its length randomly selected from integral multiples of a predetermined unit time period. The reference timing signals include a signal having the same waveform as that of the modulation signal and a signal having the same waveform as that of the inverted modulation signal. The light source (1) varies an intensity of the light in concordance with the modulation signal. The delay controller (8) delays the plural reference timing signals by the delay period (Td) to create plural timing signals respectively. The light-receiving sensor (2) accumulates the electric charges generated within the reception time period, with regard to each of the timing signals. The distance calculator (6) calculates the time difference (τ) from amounts of the electric charges respectively associated with the timing signals, and calculates a distance (L) to the target (3) on the basis of the time difference (τ) and the delay period (Td).
    • 测距装置包括光源(1),光接收传感器(2),定时控制器(5),距离计算器(6)和延迟控制器(8)。 定时控制器(5)输出调制信号和多个基准定时信号。 调制信号是交替出现高低电平周期的方波信号。 高电平和低电平周期中的每一个具有从预定单位时间段的整数倍中随机选择的长度。 参考定时信号包括具有与调制信号相同波形的信号和具有与反相调制信号相同波形的信号。 光源(1)根据调制信号改变光的强度。 延迟控制器(8)将多个基准定时信号延迟延迟周期(Td),分别产生多个定时信号。 光接收传感器(2)相对于每个定时信号累积在接收时间段内产生的电荷。 距离计算器(6)根据与定时信号相关联的电荷量计算时差(τ),并且基于时间差(τ)和时间差(τ)计算到目标(3)的距离(L) 延迟时间(Td)。
