摘要:
A drive signal generating unit generates a drive signal having a cyclic waveform containing a zero period in a vibration mode. A driver unit generates the drive current in response to the drive signal generated by the drive signal generating unit so as to supply the drive current to a voice coil. An induced voltage detector detects the induced voltage occurring in the voice coil during a nonconducting period. A zero-cross detector detects the zero cross of the induced voltage detected by the induced voltage detector. The drive signal generating unit estimates the eigen-frequency of a vibration speaker from a detected position of the zero cross and brings the frequency of the drive signal close to the estimated eigen-frequency.

An image forming apparatus includes a development device including a development roller and a driving force receiving member, a movable member configured to move the development device between a development position and a retracting position, a first driving force transmission member configured to transmit a driving force to the movable member, a second driving force transmission member configured to engage with the driving force receiving member and transmit the driving force to the driving force receiving member, and a controller configured to perform drive control for the first driving force transmission member based on a temperature detected by a sensor. If α1 represents acceleration of the development device in a case where the temperature is T1 and the driving force receiving member disengages from the second driving force transmission member and α2 represents acceleration of the development device in a case where the temperature is T2 and the driving force receiving member disengages from the second driving force transmission member, the controller performs the drive control for the first driving force transmission member so as to satisfy a relationship α1≦α2 when T1≦T2.

A color electrophotographic image forming apparatus includes a rotary to support and move developing devices to a development position without an independent driving motor for rotating the rotary. A number V of developing devices supported by the rotary are sequentially moved to and stopped at the development position in which the developing device faces a photosensitive drum. A drive transmission mechanism is provided in which each time one of a number M of claw portions of a trigger cam is disengaged from and engaged with a solenoid, the trigger cam makes a 1/M revolution, and once every 1/M revolution of the trigger cam, a driving force is transmitted to a rotary gear from a rotary drive gear which is rotated integrally with the trigger cam so that the rotary is stopped after being rotated by an angle W which is an aliquot part of (360°/N).

A color electrophotographic image forming apparatus which simplifies a configuration in which a rotary is rotated to change over respective developing devices to a development position to reduce the costs and save the space, and which simplifies the changeover operation to reduce an operating time. The image forming apparatus sequentially moves and changes over the respective developing devices supported by the rotary to the development position which faces a photosensitive drum by the rotation of the rotary. The rotary is rotated to move the developing devices. A cam is rotated integrally with the rotary, and thereby abutment portions of the cam are abutted against a regulating rotatable member so that the developing devices are spaced from a photosensitive drum. In a state in which the developing devices are abutted against the photosensitive drum, the cam is spaced from the regulating rotatable member by recesses of the cam.

A power steering system of an outboard motor to be mounted upon the body of a hull and including a steering bracket secured to the body of the hull, a swivel bracket rotatable about a body of the outboard motor and a pair of clamping brackets supporting the swivel bracket, comprises a manual steering unit for manually steering a steering element so as to operate the outboard motor, the manual steering unit including a link mechanism connected to the steering element and connected to the steering bracket, and a power unit operatively connected to the link mechanism of the manual steering unit. The power unit includes an electric motor for applying a steering assist force to the manual steering unit for reducing the steering load during steering operations through means of the link mechanism and also includes a mechanism for converting rotation of the electric motor into linear motion. The power steering system further comprises a clutch means operatively connected to the manual steering unit and the power unit and a control unit for controlling the connection of the power unit so as to be operatively disconnected from the manual steering unit. The power unit may be located upon an outside portion of the hull within a bracket or in front of the clamping bracket of the outboard motor.

A three-dimensional modeling apparatus models a three-dimensional model with a modeling material and includes a processing space, a modeling material discharging member, and a coolant supplying unit. The modeling material discharging member includes: an entrance from which the modeling material is loaded; a discharging unit that discharges the modeling material into the processing space; a transport channel through which the modeling material loaded from the entrance is transported to the discharging unit; a heating unit that heats the modeling material in the transport channel; a cooling unit provided adjacently to the transport channel between the entrance and the heating unit; and a coolant path formed inside the cooling unit. The coolant supplying unit supplies coolant into the coolant path. At least a part of the coolant path is provided between a side surface of the cooling unit along a transport direction of the modeling material and the transport channel.
