Abstract: A pair of link arms each supported at one end thereof on an engine body for swinging movement about an axis parallel to a rotational axis for a valve-operating cam are connected at the other ends, for relative turning movement about an axis parallel to the rotational axis, directly to a rocker arm having a valve abutment abutting against an engine valve and a cam abutment contacting with the valve-operating cam. At least any one of the link arms is swingably supported at one end thereof on the engine body for continuous movement within a plane perpendicular to a rotational axis for the valve-operating cam. Such an arrangement ensures that a valve-operating system can be constructed compactly, and the opening lift amount of the engine valve can be changed continuously, while ensuring an excellent followability to the valve-operating cam.

Abstract: A pair of link arms (19A and 20A) each supported at one end thereof on an engine body (1) for swinging movement about an axis parallel to a rotational axis for a valve-operating cam (16) are connected at the other ends, for relative turning movement about an axis parallel to the rotational axis, directly to a rocker arm (18A) having a valve abutment (15) abutting against an engine valve (6) and a cam abutment (17) contacting with the valve-operating cam (16). At least any one of the link arms (19A and 20A) is swingably supported at one end thereof on the engine body (1) for continuous movement within a plane perpendicular to a rotational axis for the valve-operating cam (16).

Abstract: A valve operating system in an internal combustion engine includes an associative-operation switchover means capable of switching over the associative operation of a pair of rocker arms disposed adjacent each other and the releasing of the associative-operation. The associative-operation switchover means is provided between a plurality of rocker arms including the rocker arms disposed adjacent each other. In such valve operating system, through-bores are coaxially provided in support walls of the rocker arm, and opposite ends of a roller shaft are fitted and fixed in the through-bores. A spring-receiving member is mounted to the roller shaft for receiving a return spring. Thus, when the roller shaft with the return spring of the associative-operation switchover means accommodated therein is mounted to the rocker arm, it is possible to facilitate the processing and to reduce the size and weight of the rocker arm.

Abstract: In a valve operating system in an internal combustion engine, a swinging support section provided at a base end of a rocker arm is swingably carried on a rocker shaft mounted in a cylinder head. A plurality of valve abutments are provided at a tip end of the rocker arm and capable of being individually put into abutment against upper ends of a plurality of engine valves, and a cam abutment is provided on the rocker arm in an intermediate portion between the swinging support section and each of the valve abutments to come into contact with a valve operating cam. The swinging support section comprises a thinner cylindrical portion surrounding the rocker shaft, and thicker cylindrical portions which are formed at a thickness larger than that of the thinner cylindrical portion into a cylindrical shape to surround the rocker shaft and which are integrally and continuously provided at axially opposite ends of the thinner cylindrical portion, respectively.

Abstract: In a valve operating system in an internal combustion engine, a swinging support section provided at a base end of a rocker arm is swingably carried on a rocker shaft, and tappet screws are threadedly fitted in a plurality of boss portions formed at a tip end of the rocker arm and arranged in a direction parallel to an axis of the rocker shaft, so that they can be individually put into abutment against upper ends of a plurality of engine valves. Cam abutments are provided on the rocker arm in an intermediate portion between the swinging support section and the boss portions to come into contact with a valve operating cam.

Abstract: A valve moving apparatus of an internal combustion engine has an intake camshaft with an intake variable cam piece for opening and closing an intake valve, and an exhaust camshaft with an exhaust variable cam piece for opening and closing an exhaust valve. Each variable cam piece has a low speed cam section and a high speed cam section and is movable axially relatively to the camshaft. A hydraulic driving mechanism is provided for moving the variable cam piece axially in accordance with engine operation condition. The driving mechanism has a driving piston and arms touching both sides of the variable cam piece. When valve operating characteristic of the intake valve or the exhaust valve is changed corresponding to engine operation condition, response is improved. The engine can be miniaturized.

Abstract: A camera with a magnetic recording device that may record optional data on a magnetic recording layer of a photo filmstrip while the photo filmstrip is advanced by one frame after each exposure. The optional data is print number data designating the number of copies to print from a picture frame and/or caption data designating a content and a language of a caption to print with a picture frame. The optional data is selectable by photographers for each picture frame by operating a multi-operation button when the camera is put in a mode set-up standby stage upon a shift switch being turned on by pushing a shift button. The multi-operation button is virtually divided into four sections. The camera is put in a print number setting mode when one of the sections that is provided with a mark indicating the print number setting mode, is pressed in the mode set-up standby stage.

Abstract: One of adjacent rocker arms in a valve operating system of an engine is provided with first and second support walls. A roller is disposed between the first and second support walls to come into rolling contact with cams. A cylindrical roller shaft, supporting the roller, is provided between the first and second support walls, so that a switchover pin of an associative-operation switchover means can be slidably fitted into the roller shaft in response to the movement thereof. The roller shaft is press-fitted into at least a second one of the first and second support walls, and a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the other rocker arm is set smaller than a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the roller.

Abstract: In a selectable data recording mode for setting freely selectable character data and for recording them on a photographic film concurrently with photographing, an array of characters is displayed as data to be revised. One of these characters is designated to be changed by shifting the position of blinking along a linear display. Thereafter, upon depression of a key, a plurality of character groups of various kinds are displayed from one kind to another in a predetermined sequence. When a desired kind of character group is displayed, a desired one of character groups of this kind is selected by another key, and a character to be set is selected from among the one group. Each time a character to be set is selected, the character is temporarily stored in a memory, and the character data to be revised are displayed so as to designate the next character to be changed and, thereafter, the character groups are displayed so as to permit selecting a new character to be set.

Abstract: Continuous photography control for a camera wherein an autofocus system is provided, and a motor is used commonly to move a taking lens for focusing and to open and close a shutter for exposure. When a mode switch is operated to set a continuous photography mode wherein plural exposures are continuously performed, the motor is driven to move the taking lens from an initial position into an in-focus position that is determined by the autofocus system and, thereafter, to open and close the shutter a selected number of times while maintaining the taking lens in the in-focus position. The taking lens is returned to the initial position after the selected number of exposures are performed.
