    • The amount of a paint for forming a porous heat-resistant layer supplied to the outer surface of a gravure roll is adjusted by removing the paint with a blade that is disposed so as to contact the outer surface. A resin blade is used, and the position at which the resin blade contacts the outer surface of the gravure roll is changed as the resin blade wears away. This prevents the amount of the paint for forming the porous heat-resistant layer removed from the outer surface of the gravure roll from changing as the resin blade wears away, so that the excess amount of the paint carried on the outer surface of the gravure roll is removed with good accuracy. An almost constant amount of the paint is thus transferred to an electrode surface from the outer surface of the gravure roll, and a porous heat-resistant layer with an almost uniform thickness is stably formed on an industrial scale.
    • 供给到凹版辊的外表面的用于形成多孔耐热层的涂料的量通过用设置成与外表面接触的刮板去除涂料来调节。 使用树脂刀片,并且树脂刀片与凹版辊的外表面接触的位置随着树脂刀片磨损而改变。 这样可以防止由于树脂刮刀磨损而从凹版辊的外表面除去形成多孔耐热层的涂料量的变化,从而使得在凹版辊的外表面上承载的过量的油漆 被精确地移除。 因此,几乎恒定量的涂料从凹版辊的外表面转移到电极表面,并且工业规模稳定地形成具有几乎均匀厚度的多孔耐热层。

    • A hetero semiconductor corner region, which is a current-concentration relief region that keeps a reverse bias current from concentrating on the convex corner, is arranged in a hetero semiconductor region. Thereby, a current concentration on the convex corner can be prevented. As a result, an interrupting performance can be improved at the time of interruption, and at the same time, the generation of the hot spot where in a specific portion is prevented at the time of conduction to suppress deterioration in a specific portion, thereby ensuring a long-term reliability. Further, when the semiconductor chip is used in an L load circuit or the like, for example, at the time of conduction or during a transient response time to the interrupted state, in an index such as a short resistant load amount and an avalanche resistant amount, which are indexes of a breakdown tolerance when overcurrent or overvoltage occurs, the current concentration on a specific portion can be prevented, and thus, these breakdown tolerances can also be improved.
    • 作为将反向偏置电流保持集中在凸角上的电流 - 浓度释放区域的异质半导体角区域设置在异质半导体区域中。 由此,可以防止凸角上的电流集中。 结果,在中断时可以提高中断性能,同时,在导通时防止特定部位的热点的产生,抑制特定部分的劣化,从而确保 长期可靠。 此外,例如在导通时或半导体芯片用于L负载电路等时,例如,在短时间响应时间到中断状态时,以诸如短路负载量和雪崩阻抗的指标 量是当发生过电流或过电压时的击穿容限的指标,可以防止特定部分上的电流浓度,因此也可以提高这些击穿公差。

    • A method for forming an electrode for a battery includes the step of forming a porous layer on the surface of an electrode hoop formed at its surface with a mixture layer containing an active material. The porous layer is formed in the following manner: A gravure roll is rotated oppositely to the direction of movement of the electrode hoop while being allowed to abut against the surface of the moving electrode hoop, thereby applying a coating fluid serving as a precursor of the porous layer to the surface of the electrode hoop. A plurality of grooves formed in the circumferential surface of the gravure roll extend in parallel in oblique directions against the rotation direction of the gravure roll from the central line of the circumferential surface to the outer edges of the circumferential surface so as to be arranged in a symmetrical manner relative to the central line.

    • An electrostatic discharge protection circuit and a semiconductor device that prevent the breakdown of a semiconductor device caused by an electrostatic discharge (ESD) which suddenly changes. When voltage which is far higher than VDD1 is applied to a power supply line as a result of an ESD, a great electric potential difference is produced between VDD1 and VSS. At this time an electric current path for making an electric charge generated by overvoltage flow to a grounding line is formed by a clamp circuit. As a result, an electric current flows into GND of a circuit block. This prevents the production of a great electric potential difference between VDD1 and VSS. In addition, at this time a rapid change in the level of the overvoltage applied to a signal line is suppressed by a protection circuit. This prevents the dielectric breakdown of gate oxide films of transistors included in a circuit block which receives a control signal.
    • 一种防止由突然变化的静电放电(ESD)引起的半导体器件击穿的静电放电保护电路和半导体器件。 当远高于VDD1的电压作为ESD施加到电源线时,在VDD1和VSS之间产生大的电位差。 此时,通过钳位电路形成用于使由过电压产生的电荷流向接地线的电流路径。 结果,电流流入电路块的GND。 这样可以防止在VDD1和VSS之间产生很大的电位差。 此外,此时,通过保护电路来抑制施加到信号线的过电压的电平的急剧变化。 这防止包含在接收控制信号的电路块中的晶体管的栅极氧化膜的介电击穿。
