摘要： Optical-beam 2 emitted from semiconductor laser device 1 is transformed into parallel-light 4 by means of collimator lens 3, and a part of parallel-light 4 passed through parallel glass-plate 7 of which the front-surface is mirror finished and the rear-surface is frost finished is inputted into detector 5 monitoring the light-quantity. The optical-beam reflected from parallel glass-plate 7 is focused on information medium 9 after it passed through a collimator-lens 6. The optical-beam reflected from information medium 9 is then introduced on a detector disposed on the semiconductor laser device taking an reversed course. Since no interference of light transmitted through detector 5 is generated in this optical head, a higher linearity of the output of detector 5 can be obtained so that the better stabilized output control of semiconductor laser device 1 by means of laser control circuit 11 can be obtained.

摘要： In an optical head, two object lenses 3a, 3b fixed to a lens holder 4 are provided to serve as means for condensing a light beam 11 wherein these object lenses 3a, 3b are at positions eccentric from a support axis 10. The object lenses 3a and 3b are fabricated to satisfy prescribed conditions to suppress aberration. When either object lens 3a or 3b is selected for an optical recording medium 17, 18, degrading of signals can be prevented. Alternatively, two light sources 14, 25 are provided for one object lens 19, and the object lens is fabricated to satisfy prescribed conditions to suppress aberration. When either one of the light sources is used, degrading of signals can be prevented. In a different optical head, a recording medium 107 is set on a disk driving device 111, and an optical head 115 is provided movable freely in radial directions. The tilt of the recording medium is detected with a sensor, and the optical axis of the beam is controlled according to the detected tilt to cancel aberration.

摘要： To present an objective actuator small in the number of parts, easy in soldering and assembling, heightened in the motion precision and brake effect, free from undesired resonance due to torsional motion of the objective lens holding member, heightened in the secondary resonance frequency by the torsional motion of the objective lens holding member, and suppressed of its amplitude. A lens holding member holding an objective lens and a housing are simultaneously and integrally molded through four linear spring members inserted in a die. Afterwards, a pair of magnets are fixed on the lens holding member, and an electromagnetic coil is wound, and wire terminals are wound in the wire arrangement grooves, then a soldered coil frame is fixed on the housing. A brake member is injected into the recess space enclosing linear spring members with the inside of the side wall of the housing and the inner wall, the brake frame, its partition wall, and part of the coil frame, from the side surfaces. The objective lens is mounted on the middle and top of the lens holding member holding the objective lens, and an optical plate is fixed in the middle of the lower surface, thereby forming a rigid nearly hexahedral structure, in which the suspension center by the linear spring members and the driving center by the driving system of the electromagnetic coil and magnets are matched, and the moment balance of the lens holding member including the objective lens and optical plate is achieved on this driving center.

摘要： The sonic soot blower includes a sonic wave oscillator that oscillates sonic waves by compressed air or steam, a frequency-regulating portion that varies the frequencies of the sonic waves oscillated by the above-described sonic wave oscillator, a resonance tube that resonates the oscillated sonic waves, and a horn that amplifies the same, wherein powdery dust adhered to members installed inside a boiler furnace, etc., are removed, and are prevented from adhering to the above-described members. The above-described frequency-regulating portion is a gas mixer which is connected to the upstream side of the sonic wave oscillator and is provided with two or more gas conducting flow channels for conducting a compressive gas whose temperatures and/or densities are different from each other, or a slide mechanism that varies the length of the above-described resonance tube. Since the sonic soot blower is able to oscillate sonic waves while regulating the oscillation frequency so as to be suited to the operating conditions of the boiler, it becomes possible to effectively remove ash from the heat transmission tubes and to effectively prevent the same from adhering thereto over a wide range of operating conditions of soot blower-installed equipment (such as a boiler).

摘要： A plurality of movable lenses included in a zoom lens system are driven individually by piezoelectric actuators provided one for each lens. Two driving rods are arranged at different positions along the same line in such a way that neither of the driving rods reaches into the driving stroke of the lens driven by the other. Each driving rod has a piezoelectric actuator provided at its end farther from the other. Alternatively, a plurality of piezoelectric actuators are fixed to a single base block having a groove or a surface level difference to restrict propagation of vibration between the piezoelectric actuators. A graduated member having N-pole and S-pole regions formed alternatively thereon with a predetermined pitch is fixed, parallel to the driving rods, to the driving device itself. A magnetic resistance sensor is attached to each lens frame so as to face the graduated member. Based on the outputs of the sensors, the positions of the individual lenses are detected.
