A cleaning unit provided in a xerographic image forming apparatus removes residual toner from a photosensitive belt after a transfer process for transferring a developed image from the photosensitive belt to a recording sheet. The cleaning unit includes a cleaning blade for scraping the residual toner from the photosensitive belt, and a housing for storing the residual toner scraped by the cleaning blade. The cleaning blade has a slanting surface formed between a top surface of the cleaning blade and an end of the cleaning blade, the slanting blade slanting from the top surface toward the end of the cleaning blade so as to be inclined at a predetermined angle with respect to the top surface. The developer scraped by the cleaning blade is entered in the housing via the slanting surface and the top surface of the cleaning blade. The cleaning unit further includes a sweeping plate for feeding the residual toner scraped from the photosensitive belt by the cleaning blade into the housing, via a top surface of the cleaning blade.

A system for calculating a movement direction and position of a movable object such as an unmanned vehicle running within a factory and a method therefor are disclosed in which an image pick up camera such as a video camera photographs a background of the movable object to generate a background two-dimensional image. Positions of vanishing point and side ends of a passage on which the movable object is to move are derived from the background photographed two-dimensional image. The movement direction of the movable object is derived from the detected vanishing point. Distances of the movable object from both sides ends of the passage are derived on the basis of the detected vanishing point and positions of side ends of the passage. the movement direction and position of the movable object thus detected are used to control movement of the movable object. The vanishing point is detected on the basis of edge directions at all points constituting and edge on the background two-dimensional image.

The present invention relates to an optical reader for scanning a surface to be scanned by using information beam ray such as laser beam ray and optically reading a recorded information such as bar code recorded in the surface to be scanned. The optical reader is constituted such that optical beam emitted from a light source is reflected on a first rotary multiface mirror to scan on a surface to be scanned, and information beam reflected on the surface to be scanned is reflected on a second rotary multiface mirror to guide to an opto-electric transforming means. A scanning optical path for permitting the optical beam from the light source to pass therealong is formed independently from a reflecting optical path for permitting the information beam from the surface to be scanned to pass therealong. A condensing lens system including a bore diameter large enough to cover the scanning optical path and reflecting optical path as well as a single optical axis is disposed between the surface to be scanned and the first and second rotary multiface mirrors.

A cleaning member includes a core bar, an elastic coating layer, and high-friction coefficient parts provided on both ends of the cleaning member. The high-friction coefficient parts include an elastic material. Outer peripheries of the high-friction coefficient parts are inclined with respect to an axial direction of the core bar. The cleaning member is roller-shaped and is configured to clean a surface of a roller member to be cleaned in contact therewith. A charging device and a process cartridge also include the cleaning member.

A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost thereof.

In recording materials of a video program or the like, the video materials are efficiently and optimally acquired so that processing steps in and after an editing step subsequent to a recording step can be reduced. A recording support information (metadata) on a schedule of and a performer for an imaging operation, and the like, which are determined in advance is recorded in a first recording medium 16 by a program constitution input device 100. The first recording medium 16 is inserted in to an imaging device 200, materials to be recorded are classified and confirmed based on the metadata, and the materials which can constitute a desirable program as potentially as possible are acquired in the recording operation.

A lead frame includes a frame body defining an internal region, a plurality of leads extending from the frame body, and first and second stages that are disposed in the internal region. The first and second stages are sloped and are parallel to a first line along which a primary stream of a molten resin runs, so that slope angles of the stages are not substantially changed by the injection of the molten resin into the cavity.

A physical quantity sensor includes a pair of physical quantity sensor chips that are inclined with respect to the bottom of an exterior mold package whose side surfaces are each inclined in a thickness direction by an angle ranging from 0° to 5° and are formed in proximity to the outer ends of the physical quantity sensor chips. It is possible to realize the inclination of stages without using molds, wherein absorption devices are used to absorb prescribed portions related to stages, which rotate about axial lines and are thus inclined with respect to a prescribed base. In manufacturing, a thin metal plate having a plurality of lead frames is placed on a base delimited by a clamp; then, intersecting points of intermediate portions formed between the lead frames are subjected to pressing so as to realize the inclination of stages.

A semiconductor device is designed such that a semiconductor sensor chip having a diaphragm for detecting pressure variations based on the displacement thereof is fixed onto the upper surface of a substrate having a rectangular shape, which is covered with a cover member so as to form a hollow space embracing the semiconductor sensor chip between the substrate and the cover member. Herein, the substrate is sealed with a molded resin such that chip connection leads packaging leads are partially exposed externally of the molded resin; the chip connection leads are electrically connected to the semiconductor sensor chip and are disposed in line along one side of the semiconductor sensor chip; and the packaging leads are positioned opposite the chip connection leads by way of the semiconductor sensor chip. Thus, it is possible to downsize the semiconductor device without substantially changing the size of the semiconductor sensor chip.
摘要:
A semiconductor package encapsulating a semiconductor chip provides inner leads and outer leads for establishing electrical connections with the substrate. Herein, a lead frame is set into the metal mold, into which a resin is injected and which is clamped in proximity to the outer leads. Thus, the semiconductor package is sealed so as to avoid unwanted formation of resin burrs around lower surfaces of the inner leads. In addition, a semiconductor device is produced using a package in which a semiconductor chip mounted on a stage and terminals are embedded within a resin. Each terminal provides an electrode surface, an interconnecting portion, and an exposed terminal surface. Herein, an isolation portion is formed as an integral part of the package made by the resin and is arranged in the prescribed area between the electrode surface and the exposed terminal surface.
