An optical system comprising: an optical element having an optical property responsive to an applied signal, a variation of the optical property with the signal exhibiting hysteresis in a first range of values and no hysteresis in a second range of values of the signal; a memory storing data representing a hysteresis curve which indicates the variation of the optical property with increasing and decreasing values of the signal; and a controller which continuously controls the optical property by: generating, based on the stored data, a cyclic signal having a discontinuity in each cycle of the cyclic signal, and setting the discontinuity size in each cycle based on the stored data such that a part of the variation of the optical property with the cyclic signal coincides with a part of the variation represented by the stored data; and applying the cyclic signal to the optical element.

Optical element control

An electronic device includes: an operation unit; a detection unit that detects a position or an orientation; a communication unit that communicates with an external device including an image capture unit; and a storing unit that stores image data, wherein the communication unit receives image data generated by the image capture unit from the external device after transmitting information instructing the image capture unit included in the external device to capture an image in response to an operation of the operation unit, and the storing unit stores the image data received and information on the position detected by the detection unit or information on the orientation detected by the detection unit.

An exhaust emission control apparatus for a general-purpose internal combustion engine comprises an exhaust passage allowing passage of an exhaust gas therethrough and having a ternary catalyst, and an air pump for supplying a secondary air to the exhaust passage. The air pump is driven by rotation of a camshaft having a cam for opening and closing an exhaust or intake valve of the internal combustion engine. The drive of the air pump is effected by a pump rocker arm disposed between the cam and a pump shaft of the air pump.

A cam shaft having a cam piece disposed on a locking member or plurality of locking members provided on a shaft at predetermined positions. A recess or recesses formed in the cam piece align with and engage the locking members disposed on the shaft. The cam piece is secured to the shaft by a resin injected into and around the recess such that the cam piece is integrally fixed on the shaft when the resin hardens.

An air-cooled internal combustion engine has a cylinder block, a piston slidably disposed in a cylinder in the cylinder block, and a cylinder head mounted on the cylinder block and having a partly spherical combustion chamber aligned with the cylinder. An intake valve, an exhaust valve, and a spark plug which are mounted in the cylinder head are oriented radially outwardly from the axis of the cylinder and angularly spaced from each other by distances that are progressively increased in the direction along the axis of the cylinder. The intake valve, the exhaust valve, and the spark plug have respective central axes inclined at the same angle to the axis of the cylinder, and the intake valve, the exhaust valve, and the spark plug are angularly spaced at equal angular intervals as viewed along the axis of the cylinder.

A catalytic reactor includes a reactor vessel, a catalyst bed and at least two heat exchangers. The catalyst bed and heat exchangers are arranged coaxially with the central axis of a reactor vessel and substantially at the same height.

In a diesel engine having a valve operating chamber within which are accommodated intake and exhaust valves, driving system operable to open and close under control those valves, and a unit injector consisting of an injection nozzle and an injection pump united together, it is arranged that the unit injector is designed into an L-shape with its horizontally extending portion being formed by the injection pump, a cam shaft being located below the injection pump, and first and second rocker shafts of the driving system being disposed on both sides of the unit injector.

A rear suspension system for motor vehicles. Both leg ends of a gate-shaped swing arm which at its free end supports the central part of a rear axle are pivotably secured to a vehicle body frame, a tension rod is provided between the lower end of a downwardly extending swing link mounted near the free end of the swing arm and a portion of the vehicle body frame near and below the above pivoted point of the swing arm, and one end of a damper disposed between both legs of the swing arm in a position above the tension rod is mounted near and above the pivoted point of the swing arm, while the other end thereof is attached to the swing link. The rear suspension system can be mounted in a relatively narrow space, and even with devices of relatively large capacities mounted thereabout, it can exhibit its damping characteristics satisfactorily.
