Abstract: An operating hinge for a seat and seat lid of a toilet bowl, simply constructed and capable of controlling the angular moment of the seat and lid to softly stop them in place at their respective predetermined ends of pivoting stroke, provided.

Abstract: A tilt hinge supports a cover so that the cover can lightly be opened and can be held in an inclined position at an optional angular position. The tilt hinge comprises: a mounting member having a mounting plate and a bearing plate, and attached to a main unit of a machine; a stepped shaft having an expanded section and a reduced section of a diameter smaller than that of the expanded section, supported for rotation on the bearing plate; a support member for supporting a cover, fixed to the shaft; a torsion coil spring wound around the shaft and resiliently engaged between the support member and the mounting member; and a friction mechanism interlocked with the bearing plate and the shaft.

Abstract: A first rotating shaft supporting an opening-closing body and rotating with the opening and closing operation of the opening-closing body is rotatably mounted on a mounting member attached on an apparatus body side. A first friction mechanism works on the rotating shaft. A main driving gear is mounted on the first rotating shaft so as to rotate together with the first rotating shaft. A second rotating shaft is mounted on the mounting member; on the second rotating shaft a driven gear engaged with the main driving gear is mounted to rotate with the second rotating shaft. Also, on the second rotating shaft a second friction mechanism works. Furthermore, a click stop means works on the first rotating shaft.

Abstract: In order to control the rotational torque of opening/closing bodies, such as seats and lids for Western-styled lavatory stool, allowing them to be easily opened, stopped and held stably in an opened state, and preventing them from dropping abruptly when they are closed, the present invention provides an opening/closing device with a pair of brackets fitted on two sides at the upper end of the rear part of a lavatory stool and a pair of cases, one for each of the pair of brackets, for bearing and holding one side of a corresponding bracket. A holder housing receives each of these cases, and has a fitting part for a lavatory lid, and is disposed rotatably between the pair of brackets. A pair of supporting members for the lavatory is positioned outside the brackets, and is borne and held by the cases.

Abstract: A hinge mechanism for a toilet bowl seat or seat lid has improved control of rotation due to torque exerted by a cam member working with a compression spring and slider, such that the torque varies depending on the angle of the seat or seat lid to the plane of the toilet bowl. The slider and cam member are mounted on a shaft having an axially directed oval hole in which a complementary shaped hinge pin is received to connect the seat and the seat lid to the mechanism. A stop mechanism prevents the shaft from turning beyond a predetermined angle.

Abstract: A hinge mechanism has a damping mechanism and is capable of removing or reducing to the least extent the damping action of the damping mechanism when opening the seat or the seat lid of a toilet bowl, of securely holding the seat or the seat lid at the open position, of making the damping action effective so that the seat or the seat lid can turn gradually to its closed position and of avoiding the breakage of the damping mechanism due to jerky loading when the seat or the seat lid is turned with a jerk. The hinge mechanism comprises a case, a hinge shaft supporting the seat or the seat lid and supported in the case for rotation and axial movement, a fluidic damping mechanism formed between the case and the hinge shaft, and a resilient means biasing the hinge shaft in one direction.

Abstract: Disclosed is a signal processor for an ultrasonic fish detector, in which the signal processing circuit is arranged separately from the display unit, whereas conventionally both are configured integrally, within a case with the provision of a composite converting circuit and RGB converting circuit with associated video output terminal and RGB output terminal, thereby allowing the user to configure a fish detection system by merely purchasing the fish detection signal processor made up of the signal processing circuit and a transducer and utilizing a home television set or an RGB graphics monitor oriented to personal computers.

Abstract: The present invention relates to a record playing device adapted to be attached to a cabinet of a record player.In order to facilitate the assembling of the record player as much as possible, the record playing device of the invention has a unit construction comprising a single base plate 1 which carries, at least: a turn table driving motor having a turn-table shaft and a pinion; a gear wheel for intermittent engagement with the pinion; a returning plate adapted to be moved reciprocatingly to the right and left in accordance with the rotation of the wheel gear; a sliding lever adapted to move reciprocatingly to the left and right to actuate link pawls pivoted to the gear wheel thereby to initiate the mutual engagement between the pinion and the wheel gear; and a microswitch for controlling the operation of the turn-table driving motor and adapted to be opened and closed in accordance with the positional relationship between the sliding lever and the returning plate.

Abstract: This invention deals with a hinge for opening or closing a dust cover of record players, which, in order to keep the hinge body from being exposed, to prevent the opened dust cover from excessively projecting rearwardly and to stably sustain the dust cover at an intermediate opening angle, comprises: a cabinet; a dust cover; a slider disposed vertically slidable in the rear portion of the cabinet on each side; a spring urging the slider upward; a support member removably mounted to the dust cover and rotatably mounted on the cabinet by a hinge pin; and a follower provided to the support member and adapted to contact the head of the slider. The hinge of this invention may be provided, in addition to the above construction, with a means to stably sustain the dust cover at an intermediate opening angle.

Abstract: In a record player, the movement of the tone arm is controlled by a select plate operated by a lever which moves the plate to a position corresponding to a record size. Adjacent the select plate is a C-shaped lever which cooperates with a rotary member. The rotary member has a plurality of cams which serve to program the operation and various movements of the tone arm. Extending from the peripheral edge of one of said cams is a brush. The tone arm is also responsive to a bracket with a wall, said wall being engaged by the brush. A position detector plate is mounted on the bracket which cooperates with a photo-interrupter to detect the position of the tone arm with respect to a record being played.

Abstract: A hinge arrangement for a record player to properly distribute the load over a glass cover and avoid imposing an unduly large load around the mounting holes. There is provided a cover retainer with a pair of hinge plates having side plate portions which define a receiving space for a pair of anchoring lugs and a hinge pin, on one of said hinge plates. The side portions on the other hinge plate are received by and fixed in said defined space and retained at the center point by the anchoring lugs so as to prevent the other hinge plate from rotating back away from the one hinge plate. Attaching screws are provided on one of said hinge plates for fixing the cover inserted in the cover retainer.
