Abstract: A coupling device, having a simple structure, prevents leakage of fluid from an auxiliary valve in a female coupler. The coupling device seals fluid containing air in the female coupler, even in the pressure of the fluid remains or is as low as the ambient pressure level when the male coupler is separated from the female coupler. An annular seal, having integrally formed first and second annular seal elements, is provided in the female coupler. The first annular seal seals between a protruded cylindrical member of the male coupler and a mating cylindrical member of the female coupler. The second annular seal forms a valve body portion of the cylindrical member of the female coupler.

The clutch mechanism has a shift cam which is remotely operable through a clutch rod and a shift rod, so as to switch the direction of rotation of a propeller shaft within a gear case. The clutch mechanism has an assist device acting between the clutch rod and the shift rod. The assist device has a rotary drive member connected to the clutch rod, a rotary driven member connected to the shift rod and driven by the drive member, and an elastic member disposed to act between the drive member and the driven member.

Abstract: An insulative circuit board receives a forged terminal and a simplified terminal plate, inserted through a through hole and guided by insertion slots, to form a complete terminal connector. The terminal plate firmly fixes to the insulative circuit board by locking into integrally formed locking steps. The terminal is retained by the snap-in terminal plate. and preventive elements formed integrally with the circuit board. Preventive elements prevent unexpected disassembly when the terminal and the terminal plate loose threaded engagement and eliminates the need for after-integration processing. A guiding element, integral with the terminal, guides the terminal into threaded engagement with the terminal plate. The guiding element also prevents damage to a terminal plate screw hole and speeds assembly.

Abstract: A flat cable connector has one or more contact bodies. Each contact body is formed from a bent plate body and has a terminal part and a circuit board contact part. The terminal part of the contact has a u-shape for contacting a flexible circuit board. The circuit board contact part has a flexible curved end for contacting a main circuit board. A housing case is positioned around the contact bodies and has openings on at least one side. The openings are positioned to expose parts of the contact bodies and include an insertion hole and a contact hole. The insertion hole provides access for a connection terminal part of a main circuit board to the circuit board contact parts of the contacts. The contact hole provides access for a flexible circuit board to the terminal parts of the contacts. A moveable cover fits loosely in the insertion hole and anchors the flexible circuit board to the terminal parts of the contacts to form an electrical connection.

Abstract: The invention relates to a circuit with low parasitic inductances, reduced current flow paths, and reduced current-circumfusion. The circuit includes a ceramic substrate supporting mutually insulated metallic connection webs and a first and a second series-connected power switch. Each power switch includes a first and a second power transistor connected in parallel and DC and AC leads. The insulation layer separates the conduction webs from a supporting substrate and is effective to minimize any parasitic inductances in the circuit arrangement.

Abstract: A rotation detection device is provided in a motor roller of a conveying apparatus to detect changes in the rotation speed of the motor roller. When an object is moved from an upstream location of a conveyance path to the motor roller having the rotation detection device, the rotation detection device detects the presence of the object by measuring the slight variation in rotation speed of the motor roller. A control unit is provided to monitor the output signals from a plurality of rotation detection devices, arranged along the conveyance path. The control device independently adjusts the conveyance speeds of a plurality of independent conveyance portions along the conveyance path based upon these output signals. This system allows conveyance of a plurality of objects along the conveyance while avoiding one object from running into another object due to, for example, a delay at a particular point along the conveyance path.

Abstract: Roller member connectors facilitate quick change of tools used by robot hands. Each roller member includes a pair of projections on either side thereof. On the inner surface of each retainer opening, a pair of guide grooves are formed to guide the projections so that they are retained during operation.

Abstract: The severed trailing edge of a two-ply web is spliced to a leading edge of a replacement web on a replacement roll in a two-part operation which permits on-the-fly splicing. The upper ply of the replacement web is trimmed back to reveal a strip of the lower ply. A splice tape is placed under the edge of the lower ply with a portion of the splice tape exposed. A splice roll is prepared with a splice sheet having first and second adhesive strips spaced apart on it. The replacement roll and splice roll are accelerated to synchronize their peripheral speeds with the web speed. The rotational phases of the replacement roll and splice roll are coordinated. A bump roll is triggered to urge the web against the replacement roll. A cut-off knife is triggered to sever the web. The bump roll and cut-off knife trigger are timed so that the trailing edge of the severed web falls into contact with the exposed portion of the splice tape. This splices the lower plies together.

Abstract: Branching pipes connect a surge tank to an intake manifold of an internal combustion engine. The branching pipes are made such that each gas column of the internal combustion receives a uniform intake volume. This is achieved by either making each branching pipe of the same length, or by adjusting the inside diameters of the branching pipes, thereby creating a flow delay of the intake into the gas columns, resulting in uniform intake volume. The inside diameters of the branching pipes are either made uniformly of a different diameter, or, alternatively, the inside diameters of the branching pipes include throttles for reducing the diameter of the branching pipe at a localized portion. In both cases, a flow delay of the intake into the gas columns is compensated, resulting in a uniform intake volume.

Abstract: A fluorescent conversion filter suppresses decomposition and quenching of fluorescent dyes or pigments. An organic light-emitting device may be equipped with such a fluorescent conversion filter. The fluorescent conversion filter is formed by coating with a coating material, followed by patterning by photolithography. The coating material consists of a mixture of organic fluorescent dye or pigment that absorbs light in the ultraviolet to visible light region. The coating also includes a photo-setting or photo-and-thermo-setting resin containing a photopolymerizaion initiator of a hydrogen abstraction type having a benzophenone skeleton within the molecule. As a result, an organic light-emitting device is produced by combining the a fluorescent conversion filter with an organic light-emitting element.
