    • An optical recording disc comprising two disc substrates, each in a cylindrical shape having a round center hole, at least one recording layer formed on the surface of at least one said disc substrate, and at least one bonding material layer is formed at an inner rim portion and an outer rim portion of the surface of the said disc substrate, on the surface of which the recording layer is formed, except for at least one portion of the said rim portion of the surface of the disc substrate, wherein the bonding material layer is provided to bond the said two disc substrates togehter, so that the surfaces of the said disc substrates, on the surface of which the recording layer is formed, face each other, thereby a space gap is formed between the said disc substrates, and the said one portion of the said rim portion of the surface of the disc substrate, where the bonding material layer is not formed, can act as a ventilation path, through which the air can pass from the said air gap into the outside of the optical recording disc, and reversely. Accordingly, the said ventilation path enables to prevent the shape of the disc substrate from changing and also enables to prevent the disc substrate from breaking, even if there is a pressure difference between the inside air gap and the outside of the optical recording disc, thereby the optical recording disc can record information correctly on the recording layer.
    • 一种光记录盘,包括两个圆盘形基板,每个圆盘形圆柱形具有圆形中心孔,至少一个记录层形成在至少一个所述盘基片的表面上,至少一个接合材料层形成在内边缘 部分和所述盘基片的表面的外边缘部分,除了所述盘基片表面的所述边缘部分的至少一部分之外,其表面上形成有记录层,其中所述接合材料层 被提供以将所述两个盘基片连接起来,使得所述盘基片的表面上形成记录层的表面彼此面对,由此在所述盘基片之间形成间隙,并且 所述盘基片表面的所述边缘部分的一部分,其中未形成所述接合材料层,其可以用作通气路径,空气可以通过所述通气路径从所述气隙传递到 在光学记录盘之外,并且反向。 因此,即使在内部空气间隙和光记录盘的外部之间存在压力差,所述通气路径也能够防止盘基板的形状发生变化,并且还能够防止盘基板破裂,由此 光记录盘可以在记录层上正确地记录信息。

    • According to this invention, a well region is formed on a semiconductor substrate. An n.sup.+ -type first semiconductor region is formed in the well region, and an input pad for receiving an external signal is connected near the first semiconductor region. This input pad is connected to an input circuit of an integrated circuit constituted by an inverter circuit and to an external terminal for receiving an external signal. N.sup.+ -type second semiconductor regions are formed in the well region located on both sides of the first semiconductor region. A ground potential Vss is applied to these second semiconductor regions. A p.sup.+ -type third semiconductor region is formed around these second semiconductor regions in the well region. The ground potential is applied to the third semiconductor region. Therefore, a parallel circuit formed by a parasitic transistor and a parasitic diode is formed between the input pad and the ground potential. The parasitic transistor is turned on upon electrostatic discharge, and the parasitic diode is turned on when a negative potential for test is applied to the input pad, thereby preventing an erroneous operation of a transistor arranged on the semiconductor substrate.
    • 根据本发明,在半导体衬底上形成阱区。 在阱区中形成n +型第一半导体区,并且用于接收外部信号的输入焊盘连接在第一半导体区附近。 该输入焊盘连接到由逆变器电路构成的集成电路的输入电路和用于接收外部信号的外部端子。 在位于第一半导体区域的两侧的阱区中形成N +型第二半导体区域。 对这些第二半导体区域施加接地电位Vss。 在阱区中围绕这些第二半导体区域形成p +型第三半导体区域。 接地电位施加到第三半导体区域。 因此,在输入焊盘和接地电位之间形成由寄生晶体管和寄生二极管形成的并联电路。 寄生晶体管在静电放电时导通,当向输入焊盘施加用于测试的负电位时,寄生二极管导通,从而防止布置在半导体衬底上的晶体管的错误操作。

    • A single-use instant camera includes a main body, having the taking lens and the shutter mechanism. A film unit containing chamber is formed in the main body, and contains a plurality of instant the film units stacked on one another. The containing chamber is opened toward a rear and has a front wall. An exposure aperture is formed in the front wall, and receives the image-recording portion of the film units, to provide the film units with exposure to light a entered through the taking lens from an object to be photographed. A front cover is disposed in front of the main body to cover the main body. An advancing claw mechanism is disposed between the front cover and the main body, and advances an exposed one of the film units to be exited. A flash device is disposed between the front cover and the main body, and applies illuminating light to the object. A back lid is disposed behind the containing chamber, is engaged with the main body, and closes the containing chamber. A pressure plate is mounted on the back lid, and presses the film units toward the exposure aperture.
