    摘要： A semiconductor wafer in which black silicon does not form during trench etching even when side rinsing is carried out during a photolithography process. In an embedded oxide film interposed between first and second semiconductor wafers of a bonded SOI wafer, the film thickness of a peripheral part thereof is made greater than a predetermined thickness Dsio so that it functions as an oxide film for etching prevention. When side rinsing is carried out in a resist coating process to form an opening in an oxide film for masking use in trench etching, the oxide film for masking use at the periphery is also etched during formation of the opening. Due to over-etching at that time, the oxide film for etching prevention is etched by a film thickness d1. During trench etching also, the oxide film for etching prevention is etched by a film thickness d2. Accordingly, if the film thickness Dsio of the oxide film for etching prevention is set to be greater than the film thickness d1+d2, because an oxide film remains at the final stage, the formation of black silicon can be prevented.

    摘要翻译： 即使在光刻工序中进行侧面漂洗的情况下，在沟槽蚀刻中也不形成黑色硅的半导体晶片。 在插入接合的SOI晶片的第一和第二半导体晶片之间的嵌入式氧化膜中，其周边部分的膜厚度大于预定厚度Dsio，从而其用作防止蚀刻的氧化物膜。 当在抗蚀剂涂布工艺中进行侧面冲洗以在沟槽蚀刻中用于掩模使用的氧化膜中形成开口时，在形成开口期间也蚀刻在周边使用的用于掩蔽的氧化膜。 此时由于过蚀刻，用于防止蚀刻的氧化膜被膜厚度d1蚀刻。 在沟槽蚀刻期间，用于防蚀蚀的氧化膜也被膜厚d2蚀刻。 因此，如果将用于防蚀蚀的氧化膜的膜厚度Dsio设定为大于膜厚度d1 + d2，因为氧化膜保持在最后阶段，所以可以防止形成黑色硅。

    摘要： A movie camera having: a strobe light for illuminating a subject; a shutter speed switching circuit for changing speeds of a shutter for the charge coupled device (CCD); a white balance switching circuit for adjusting the balance between color signals; an automatic gain control (AGC) circuit for adjusting amplifying gain for an image signal; a control circuit for energizing the shutter speed switching circuit so that a flash of the strobe light is terminated within the storing time of the CCD by changing the shutter speed to a higher speed, for energizing the white balance switching circuit so that the white balance is adjusted to coincide with the color temperature of the strobe light, and for fixing the gain of the AGC circuit. Accordingly, clear pictures having uniform brightness are obtained in each shot by terminating a flash of the strobe light within the storing time of CCD and by switching the shutter speed to a higher speed, and fluctuation of the brightness of pictures shot after a flash of the strobe light is prevented by fixing the gain of an AGC circuit and by making the white balance coincide with the color temperature of the strobe light.

    摘要： A three-dimensional plexifilamentary fiber (26) of a high-density polyethylene group obtained by supplying a polymer to a dissolving area in a state such that the polymer is melted by a heated screw extruder (compressing zone 13, metering zone 14 to 16), supplying a solvent (CCl.sub.3 F) into the melted polymer (feed opening 18), mixing and dissolving the polymer and the solvent to make a polymer solution, and extruding the polymer solution from a nozzle (24 in FIG. 24 ) arranged in the dissolving area into a low pressure area. A nonwoven fabric is obtained through a process in which the fiber (26) is spread by striking the fiber against a skirt portion (33) having a fiber swinging face (34) and a cushioning face (35), and this nonwoven fabric has an excellent strength, covering property, and whiteness.

    摘要： A printer which is compact, can accurately supply paper and has reduced noise characteristics. Additionally, the printer enables easy correction of paper jams and can be selectively operated in various modes according to the user's preference. The printer includes a paper feed roller which is pivotable between a paper feed position and a non-feeding position, a drive force transmitting mechanism for transmitting a drive force to the paper feed roller, a carriage reciprocatively movable along the width of the paper fed by the paper feed roller, and an intermediate transmission mechanism attached to the side of the carriage. Only when the carriage is in a stand-by position, the intermediate transmission mechanism couples with the drive force transmitting mechanism to transmit to the paper feed roller a paper-feed directional rotating force so as to rotate the paper feed roller to the paper feed position. The intermediate transmission mechanism is preferably an idler rotatably mounted on the side of the carriage. The paper feed roller is preferably driven through a planetary gear mechanism including a sun gear provided on a drive shaft, a paper-feed roller holder rotatably mounted on the drive shaft, and a planetary gear coaxially provided with the paper feed roller supported with the paper-feed roller holder.

    摘要： A video camera includes a light receiving device to enable a remote control operation to be achieved and a tally lamp to indicate a state of operation of the camera to the operator. The light receiving device and the tally lamp are installed in a housing such that when travel members disposed in a lower portion of the housing travel on an annular rail arranged on the body of the camera, the light receiving device and the tally lamp are moved to change directions thereof with respect to the body. An operator causes light to enter the light receiving device from a desired direction so as to operate the camera and to recognize a state of the operation of the camera by visually checking the tally lamp.
