摘要： Magneto-optical disk recording and reproducing devices and actuators and distance detectors for use therewith are disclosed. The mageneto-optical disk device comprises, in addition to the usual elements, a bimorph type actuator or an electromagnetic actuator for driving the magnetic head of the magneto-optical disk device. The bimorph actuator has a metallic shim whose width varies with respect to the longitudinal distance inversely porportional to the normal function of the first or the second free natural vibration mode. Alternatively, the bimorph type actuator have a recess formed on a bimorph element to expose a piezoelectric crystal which outputs a voltage corresponding to the acceleration of the vibration of the actuator; the driver circuit of the actuator reduces the driving voltage when the frequency of the voltage generated at the recess comes into the neighborhood of a higher resonance frequency of the actuator. The optical distance detector comprises a light-emitting diode and a pair of photodiodes which detects the amount of light incident thereon after being reflected at a surface of an object the distance to which is measured. The geometric parameters of the photodiodes are selected in such a manner that the output of a first photodiode decreases as the measured distance increases while the output of a second photodiode increases as the measured distance increases. Thus, the normalized differential output of the two photodiodes, from which the measured distance is determined, varies substantially linearly with respect to the measured distance. In preferred forms, the photodetectors have stepped concentric configurations so that small distances can be measured accurately and efficiently.

摘要： A system of drying moist sludge includes a drier as a main component. The drier is composed of a lower gas fluidizing section and an upper high speed fluidizing section. Moist sludge to be be dried is introduced into a mixer in which each particle is coated with the moist sludge, and the coated particles are supplied to the gas fluidizing section. Fine particles flown away from the gas fluidizing section are fluidized in the high speed fluidizing section while they are dried by heating elements. After completion of the drying operation, dried sludge particles are collected in a dust collector. Subsequently, fine dried sludge particles are conducted to a bag type dust collecting unit from which they are discharged to a sludge hopper. A part of the coarse dried sludge particles collected in the dust collector is supplied to the gas fluidizing section, a part of the same is supplied to the mixer to be mixed with moist sludge, and the balance is delivered to the sludge hopper. The gas exhausted from the bag type dust collecting unit is introduced into the gas fluidizing section as fluidizing gas. A part of the exhausted gas is extracted to the outside by a quantity substantially equal to that of the gas vaporized from the moist sludge.

摘要： With the conventional radiating truss roof support array, the inner-truss connecting members form multiple complete rings radiating from the central portion of the roof to the periphery at fixed intervals. When tension is applied to the periphery of the roof, a constricting annular compression is generated in each of the concentric rings of inner-truss connecting members. By this mechanism, the tension applied to the periphery is somewhat dissipated, and a less than optimal effect on the curvature of the dome of the roof is achieved for a given amount of tension applied to the periphery. The present invention concerns a radiating truss roof support array constructed in such a manner as to eliminate the above described problem of induced annular constriction in the concentric rings of inner-truss connecting members. This goal is achieved by interrupting the concentric rings of inner-truss connecting members at fixed intervals so that predetermined adjacent trusses are not connected together by the above mentioned inner-truss connecting members. the concentric rings of inner-truss connecting members thus formed are incomplete at predetermined portions and the annular constriction is thus eliminated. Thereby, the tension applied to the periphery of the structure is used to maximum effect in maintaining the curvature of the dome of the roof.
摘要翻译：使用传统的辐射桁架屋顶支撑阵列，内部桁架连接构件形成从固定间隔从屋顶的中心部分到周边辐射的多个完整环。当对屋顶的周边施加张力时，在内桁架连接构件的每个同心环中产生收缩的环形压缩。通过该机构，施加到周边的张力有些消散，并且对于施加到周边的给定量的张力，实现了对屋顶的圆顶的曲率的不太理想的影响。本发明涉及一种辐射桁架屋顶支撑阵列，其以这样的方式构造，以消除上述在内桁架连接构件的同心环中引起的环形收缩的问题。该目的通过以固定间隔中断内桁架连接构件的同心环来实现，使得预定的相邻桁架不通过上述内桁架连接构件连接在一起。如此形成的内桁架连接构件的同心环在预定部分是不完整的，因此消除了环形收缩。因此，施加到结构的周边的张力用于保持屋顶的圆顶的曲率的最大效果。

摘要： An apparatus in accordance with the present invention sequentially fixes the wavelength of a light beam irradiated from a light source whose oscillation wavelength sequentially varies to a plurality of different wavelengths to a recording medium to required wavelengths each capable of forming a hole at absorption spectrum of the recording medium, synchronizes timing of change of the wavelength of the light source with timing of recording or regenerating each bit of information, records the optical hole formed in a manner that each bit of information corresponds to the wavelength varying in sequence, and detects the formed hole to regenerate information. Furthermore, the holes formed by the same wavelength are recorded at the positions separated by a distance capable of avoiding interference, while the holes formed by different wavelengths in correspondence to each bit of information are recorded at nearly the same position while that position is slightly displaced at a time, and thereby information is multiple-recorded with high density.

摘要： In a photographing optical system, an autofluorescence barrier filter having a characteristic of transmitting a light having an autofluorescence wavelength and a near-infrared wavelength, and a near-infrared light cut-off filter having a characteristic of transmitting the visible light and blocking the near-infrared light are disposed to be replaceable. In the case of observing a fundus, the fluorescence barrier filter is inserted into an optical path in an observation photographing optical system, so that observation can be performed by using a near-infrared illuminating light. In the case of autofluorescence photographing, the photographing can be performed without filter switching. In the case of color photographing, at the time of observation, the observation is performed using the fluorescence barrier filter, and at the time of photographing, the photographing can be performed using the replaced infrared light cut-off filter.

The optical encoder includes a waveform, in which a phase-modulated wave is superimposed in a predetermined period over a sine-wave of a fundamental period, as a signal track (103), and an optical detector (104) for extracting the sine signal and the cosine signal of the phase-modulated wave. An operation unit (106) operates electric angles individually from the output signals of a first optical detector pair and a second optical detector pair belonging to the optical detector, and determines the sum and difference of the electric angles, thereby acquiring the electric angle and the phase-modulated wave of the fundamental period.
