摘要： An optical recording disc comprises a first bonding recess formed near an outside surface of an optical recording disc in a bonding boundary portion between a cylindrical hub and a transparent disc substrate, a disc member bonded with said transparent disc substrate through said cylindrical hub, and a second bonding recess formed near the outside surface of said optical recording disc in a bonding boundary portion between said cylindrical hub and said disc member. Accordingly, said optical recording disc can prevent remainder of a bonding material for bonding a pair of said transparent disc substrates or said transparent disc substrate and said disc member together from pushing out of the outside surface of the optical recording disc, resulting in that focusing for reading and writing an information signal can be properly performed.

摘要： 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.

摘要： 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.

摘要： An apparatus for producing a Fresnel plate has a mold assembly comprising movable and stationary molds coupled with each other. The mold assembly includes a Fresnel forming face formed on the inside of the movable mold. Melted resin is injected into the mold assembly for forming the Fresnel plate. At least one movable slit is formed through, and arranged inside, the movable mold along a circle concentric with the Fresnel plate and in intermittent or continuous fashion. The movable slit is used for blowing compressed air toward the Fresnel plate. The slit closely surrounds the center of the Fresnel plate. Ejector pins surround the Fresnel plate outside its Fresnel forming face.
