摘要:
An optical reflection sensor emits light and its reflection from a target object is received. A signal processor carries out a measurement on the received reflected light such as the distance to the target object each time the reflected light is received. Repeatability of measured values is calculated and displayed on a display device incorporated into the housing of the sensor. The display device may have two display areas such that the calculated repeatability and the measured value can be displayed simultaneously. The calculated repeatability may be compared with a specified threshold value, with the result of the comparison displayed. The housing may also incorporate an input device through which a required level of accuracy may be set.

In a structure of an ink tank having a deformable sheet that constitutes the tank and a spring for imparting a negative pressure, unstableness of the negative pressure attributable to the deformation of the sheet as a result of ink consumption is prevented. For this purpose, a plate-like member is joined to a top section of the sheet formed in a convex shape, and the spring for generating the negative pressure in the tank is mounted to the same member. This makes it possible to maintain a high volume ratio of the ink tank and to achieve stableness of the negative pressure by adequately regulating the deformation of the sheet when the sheet is displaced in the direction of retracting toward the interior of the tank as a result of a reduction of the amount of ink in the tank.

A crawler type vibratory compacting machine of the invention compacts the ground from a surface layer to a deep layer with high efficiency. The crawler type vibratory compacting machine comprises: a triangular crawler unit which includes one wide track (35) or a plurality of juxtaposed tracks (35a, 35b, 35c) wound around wheels (32, 34) arranged along the length of and above a track frame (31); and a vibrator (40) which is housed in the crawler unit. The crawler unit has opposite lateral ends of its center coupled via a first lateral shaft (23) and pins, to an arm (20) which extends from a vehicle body (10) having an operators seat (11).

An image recording apparatus includes a rotating photosensitive drum, a developing unit, a neutralizing device, and a transferring device. An electrostatic latent image is formed on a charged surface of the rotating photosensitive drum, the electrostatic latent image being developed by a developing unit and subsequently transferred by a transferring device to a print medium. The neutralizing device neutralizes the charged surface of the photosensitive drum at the point on the surface disposed downstream of the developing unit and upstream of the transferring device with respect to rotation of the photosensitive drum. A controller controls the neutralizing device according to characteristics of the print medium such as size, material, insulation, and transparency. The neutralizing device may be operated in different modes. For example, the neutralizing device may neutralize an entirety of the charged surface of the photosensitive drum only if the print medium is of a predetermined characteristic, i.e., an insulating sheet such as a transparent OHP sheet or may neutralize only selected parts of the charged surface of the photosensitive drum according to a width of the print medium.

A liquid developing head is arranged to confront a surface of an image bearing member via a developing gap and a squeeze gap and carries out a developing by use of a developing liquid. The liquid developing head includes a housing, a developing roller, supported by the housing, supplying the developing liquid to the developing gap by rotating so that a portion of the developing roller confronting the image bearing member moves in a direction which is the same as a moving direction of the surface of the image bearing member, a squeeze roller, supported by the housing and arranged on a downstream side of the developing roller in the moving direction of the surface of the image bearing member, removing a surplus developing liquid adhered on the surface of the image bearing member at the squeeze gap by rotating so that a portion of the squeeze roller confronting the image bearing member moves in a direction opposite to the moving direction of the surface of the image bearing member, a developing liquid supply path, formed within the housing and having an ejection hole located at a portion on an upstream side of the developing gap in the moving direction of the surface of the image bearing member, supplied with the developing liquid from outside, and a developing liquid recovery path, formed within the housing, forcibly recovering the surplus developing liquid in response to a suction force applied from the outside.

In a semiconductor device in which a source/drain and a wiring layer are connected to each other through an associated buried conductive layer on an upper portion of a gate electrode is made small to manufacture a highly reliable and fine MOS transistor. After a silicon oxide film has been formed on a first polycrystalline film to be aligned with a width of a gate electrode, a second polycrystalline silicon film formed on the whole surface of a substrate is selectively etched away so as to be left only on both side faces of a pattern of the silicon oxide film. Thereafter, the first polycrystalline silicon film is selectively etched away with both the silicon oxide film and the second polycrystalline silicon film as an etching mask so that the first polycrystalline film is separated with a width which is smaller than that of the gate electrode by a width of a pattern of the second polycrystalline silicon film. As a result, the buried conductive layer including the first and second polycrystalline silicon film is formed.

A screwing apparatus includes a multi-phase motor and a control device. The motor rotates a bit, installed on the motor, for rotating a screw. The control device controls a rotational speed of the motor by calculating a rotational speed of the bit based on commutation signals outputted from sensors installed on the motor, and controls a torque value of the bit by outputting instructions to the motor so that the bit is rotated at a predetermined torque value.
