摘要:
The turning machine according to the present invention includes a displacement sensor (200) which measures a distance between an immobile reference point and a position of variable point which reflects the positional displacement of the tool, the immobile reference point being able to determine a relative positional correlation relating to a variable position of tools with the progress of machining of the workpiece (W) by the tool (421). In drawings the reference point is set up in the guide bush (90). And based on the measured result by the displacement sensor, the tool is moved so that the center height of the tool and the center line of the workpiece satisfy relatively the predetermined positional correlation. Accordingly, the center height deviation amount due to heat deformation and the like is corrected.

A deflection yoke is used for a cathode ray tube (CRT) including a glass tube having a screen surface and a straight portion for accommodating an electron gun. The deflection yoke includes a main deflection yoke including first and second horizontal deflecting coils and first and second vertical deflecting coils, and a sub-deflection yoke provided at a side of the main deflection yoke towards the electron gun of the CRT. The first and second horizontal deflecting coils have substantially saddle shapes and includes first and second coil-connection-wire sections and first and second horizontal deflection sections, respectively. The first and second coil-connection-wire sections are wound in a direction perpendicular to a tube axis of the CRT and along the straight portion, respectively. The first and second horizontal deflection sections are located towards the screen surface from the first and the second coil-connection-wire sections, respectively. In the deflection yoke, magnetic lines emitted from a rear end of the horizontal deflecting coil towards the electron gun decreases. An induced voltage generated at the sub-deflection yoke accordingly decreases, and thus, a noise on a screen noise produced due to the induced voltage is reduced.

A method for manufacturing a semiconductor integrated circuit device includes the steps of forming an isolation trench in an isolation region of a semiconductor substrate, filling the isolation trench up to predetermined middle position in its depth direction with a first insulating film deposited by a coating method, filling a remaining depth portion of the isolation trench into which the first insulating film is filled with a second insulating film, then forming a plurality of patterns on the semiconductor substrate, filling a trench forming between the plurality of patterns up to predetermined middle position in a trench depth direction with a third insulating film deposited by a coating method, and filling a remaining portion of the trench into which the third insulating film is filled with a fourth insulating film that is more difficult to etch than the third insulating film. The method may also include the step of forming dummy patterns in a relatively large isolation region of isolation regions with relatively different planar dimensions before the first insulating film is deposited

摘要:
The object of the present invention is to suppress the increase of the contact resistance at the interface between the metal layer and the silicon plug in the wiring structure in which a metal layer is formed on and connected to a silicon plug. For its achievement, a lower semiconductor layer (drain) of a vertical-type MISFET is connected to an intermediate metal layer via an underlying plug composed of a polycrystalline silicon film, and a trap layer composed of a silicon nitride (TiN) film is formed on a part of the surface of the intermediate metal layer so as to surround the plug. The trap layer is formed in order to prevent an undesired high-resistance oxide layer from being formed at the interface between the plug and the intermediate metal layer.

An RF converter circuit 11 that constitutes a video signal superposing/power deriving unit 100 converts video signals generated from images taken by a surveillance camera 10, which derives a direct current voltage as a driving power from an antenna lead-in wire 6 through a filter circuit (LPF circuit 12), to radio-frequency signals. The radio-frequency signals are transmitted through the antenna lead-in wire 6 to a television receiver 2. Images taken by the surveillance camera 1 can be viewed on the television receiver 2 only by selecting the channel assigned to the surveillance camera 1. Accordingly, the driving power for the surveillance camera 1 is not relied upon a solar battery or secondary batteries, and wiring work therefor may be simplified.

In response to an operation of reversing a vehicle, a tilt motor is rotated by a specific amount in a normal direction to tilt a mirror angle to a position that permits a mirror to provide the driver with a view of the area near a rear wheel of the vehicle, while in response to an operation of releasing the reverse gear, the tilt motor is rotated by a specific amount in a reverse direction to restore the tilt angle to a normal position thereof. During the operations, a high-frequency signal generated upon switching a brush of the motor is detected using a pickup coil to determine an amount of rotation of the motor. One and the same pickup coil may be used for detection during both of normal and reverse rotations. A voltage of a battery 3 is stabilized in a motor power stabilizing circuit 10, and supplied via a motor driving circuit 8 to a tilt motor M2. Polarity of the voltage outputted from the motor power stabilizing circuit 10 is fixed. Polarity of the voltage outputted from the motor driving circuit 8 is switchable according to a switching operation of the motor driving circuit 8 based upon a driving direction instruction. The pickup coil L10 is provided between the motor power stabilizing circuit 10 and the motor driving circuit 8.
摘要:
The present invention provides an inner mirror with a built-in antenna in which an antenna angle remains unchanged regardless of adjustment of a mirror angle. The upper end of a stay 10 is mounted on a ceiling in a vehicle room. A pivot 14 is formed at the lower end of the stay 10. The pivot 14 is inserted into a mirror body 16 and fitted into a pivot supporting pmember 20 to support the mirror body 16 pivotally in three-dimensional directions. An antenna 34 is mounted on one side of the pivot 14 through shafts 28 and 30. Since the antenna 34 is mounted on the pivot 14, the angle of the antenna 34 remains unchanged, even though the mirror angle adjustment is performed by pivoting the mirror body 16.
