  • Publication number: 20050185839
    Abstract: An image processing apparatus for correcting a hue and a saturation in an input video signal of a moving picture in real time is disclosed wherein the image processing apparatus includes an extracting unit for extracting the hue and the saturation from the input video signal, a determining unit for determining a correcting amount according to the hue and the saturation extracted in the extracting unit, and a correcting unit for correcting the hue and the saturation of the input video signal based on the determination result of the determining unit. Thereby, a desired signal portion of the input video signal is arbitrary corrected in response to the hue and saturation in real time.

  • Patent number: 6679099
    Abstract: A gas sensor includes a detection element for detecting a gas component of a gas to be measured, a casing for holding the detection element and a seal member forming a reference gas space together with the casing. The seal member has an end surface exposed to the atmosphere and a through-hole for establishing communication between the atmosphere and the reference gas space. A cylindrical insert member is inserted in the through-hole of the seal member. A sheetlike air permeable filter is sandwiched between an inner surface of the through-hole of the seal member and the cylindrical insert member so as to cover an atmosphere side opening portion of the cylindrical insert member. The atmosphere side opening portion of the cylindrical insert member is retracted from the end surface of the seal member toward the interior of the through-hole, whereby an atmosphere side face of the air permeable filter is retracted from the end surface of the seal member.

  • Publication number: 20030001966
    Abstract: Video signals of a plurality of personal computers are displayed on the same screen. In addition, using one set of input devices, a plurality of personal computers are operated. Two personal computers are connected to a monitor. In addition, input devices such as a keyboard and a mouse are connected to the monitor. Video signals supplied from the two personal computers are written to a memory that stores video signals for a plurality of screens through respective buffers. From the read start address, the address range for one screen is designated and a corresponding video signal is read. A plurality of video signals are displayed in different display areas of a display portion at a time. In addition, corresponding to a display area at which a cursor is positioned using a switch operation and an input device operation, a corresponding personal computer is selected. An output of an input device is supplied to the selected personal computer.

  • Patent number: 5955826
    Abstract: A threaded portion is formed on a metal shell of a spark plug. Within a mounting base of the metal shell, a pressure sensor is arranged in such a direction that it generates an electrical signal in response to a variation in a tightening load of the spark plug. A slit is formed as a pressure-introducing channel along an axis of the spark plug in the threaded portion of the metal shell so that the slit is communicated with an interior of the mounting base.

  • Patent number: 5494624
    Abstract: An insulator composition of foamed synthetic resin is supplied to an extruder 3, and the synthetic resin is extruded onto a wire 4a continuously supplied to the extruder 3 at a temperature higher than or equal to a foaming temperature, to cover the wire 4a with the insulator composition. Then, the wire 4a covered with the insulator composition is solidified by cooling in a water-cooling trough 6 movable towards and away from the extruder 3 in a direction of supply of the wire 4a. In this operation, an outer diameter D and a capacitance C of the insulator composition are controlled such that when the water-cooling trough 6 reaches its movable limit, either a deviation .DELTA.D of a detection value of the outer diameter D from its target preset value or a deviation .DELTA.C of a detection value of the capacitance C from its target preset value is selected as a deviation (.DELTA.D or .DELTA.

  • Patent number: 5323643
    Abstract: A device for detecting a change in internal pressure of a cylinder includes a cylinder head, an ignition plug threadingly fitted into a plug insertion hole of the cylinder head. An annular piezoelectric sensor is secured in the plug insertion hole by screwing the plug into the insertion hole. The sensor has such an outer periphery that, when the ignition plug is screwed into the plug hole, a part of the outer periphery of the sensor placed is brought into engagement with an inside periphery of the plug hole and is thereby prevented from being further rotated in the screwing direction. By using a gasket having the same relative shape to the periphery of the plug insertion hole as that of the above sensor, rotation of the sensor can be prevented even when the sensor does not have such a relative shape.

  • Patent number: 5184529
    Abstract: A tool is provided for loosening or tightening a spark plug while interposing a gasket and a pressure sensor between the spark plug and a cylinder head. The tool consists of concentric, relatively rotatable inner and outer cylinders. The inner cylinder is engageable with the spark plug for rotation together therewith and for loosening or tightening the same. The outer cylinder is lockingly engageable with a cylinder head by means of an axial projection of the outer cylinder and a groove of the cylinder head. The outer cylinder is further lockingly engageable with the gasket by means of a locking leg of the outer cylinder and a peripheral cut of the gasket. The gasket is thus lockingly engageable with the cylinder head by way of the outer cylinder for preventing the pressure sensor from rotating relative to the cylinder head when the spark plug is loosened or tightened.
