    • An information recording medium of an air-sandwich sealed type is disclosed, which comprises a pair of disk-shaped substrate to form an inner space therebetween; an inner circumferential spacer and an outer circumferential spacer interposed between the pair of disk-shaped substrates; and a recording layer formed on the inner surface of at least one of the disk-shaped substrates, with an adhesive agent being applied to the surface of at least the inner circumferential spacer or the outer circumferential spacer in the form of a plurality of concentric adhesive layers, each of the concentric adhesive layers having at least one cut-away portion to which the adhesive agent is not applied to form a vent and an air passage between the surface of the inner circumferential space or the outer circumferential spacer and any of the substrates, the vent and the air passage capable of allowing the air to pass from the inner inner space formed by the disk-shaped substrates to the outside and vice versa, and the cut-away portions of the adhesive layers being shifted in position from each other.
    • 公开了一种空气 - 夹心密封型的信息记录介质,其包括一对在其间形成内部空间的盘形基板; 插入在所述一对盘状基板之间的内周隔离物和外周隔离物; 以及形成在至少一个盘状基板的内表面上的记录层,其中粘合剂以多个同心粘合剂的形式施加到至少内周垫片或外周垫片的表面 层,每个同心粘合剂层具有至少一个切除部分,粘合剂未被施加到该切除部分以形成通气口,并且在内周空间或外周间隔件的表面与任何基板之间形成空气通道 ,能够使空气从盘状基板形成的内部空间向外部通过的通气口和空气通路,反之亦然,粘合剂层的切除部分彼此位置偏移 。

    • A probe apparatus 1 includes displacement detection means 6 disposed on a surface 4a of a probe card 4 from which probing needles 41 of the probe card 4 protrude, and control means 5 for receiving a signal of a positional change of the probe card 4 from the displacement detection means or a positional change on the stage side, or signals of positional changes of both of them and moving a stage 2 in a Z axis direction. The displacement detection means detects on the real time basis the positional change of the probe card due to influences of heat, etc, moves the stage to correct the positional change and keeps the contact condition between probing needles of the probe card and electrode pads of a wafer 10 always constant.
    • 探针装置1包括设置在探针卡4的探针41突出的探针卡4的表面4a上的位移检测装置6和用于接收探针卡4的位置变化的信号的控制装置5 位移检测装置或台侧的位置变化,或者它们两者的位置变化的信号和在Z轴方向上移动平台2。 位移检测装置实时地检测由于热等的影响而引起的探针卡的位置变化,移动台以校正位置变化并保持探针卡的探针和电极垫之间的接触状态 晶片10总是恒定的。
