Filed: 1994-09-12
Abstract: PURPOSE: To suck and clean contaminated air from a wide region by sucking air from a location separated from the center of an imaginary circle with a spinning air stream in the direction of the central axis of the imaginary circle constituted by the spinning air stream. CONSTITUTION: Air sucked from an air suction inlet 106 is cleaned with an air filter and is exhausted from an air outlet 108 to the outside. Further, part thereof is blown off from air outlets 201 to 204 through air carrying pipes 102 to 105. Since the air outlets 201 to 204 are directed in the same tangential direction of an imaginary circle 205 formed taking the air suction inlet 106 as the center, a spinning air stream 206 is produced on a flat plane including the air outlets 201 to 204. The spinning air stream 206 is lowered downwardly keeping rotational energy to form a spiral air stream 109 because the air suction inlet 106 sucks air. Hereby, contaminated air in a space separated from the air suction inlet 106 can be securely sucked too and hence air in a wider space can be cleaned.

SOLUTION: In the case an externally attached stroboscopic device is not loaded (101), it is decided whether or not an AF operation may be performed with the incorporated auxiliary light having no pattern projection. That is, based on the accumulation time of the AF sensor at the last focusing detecting time (102), the focus detecting operation is performed by using the incorporated auxiliary light (103) in the case the last luminance is low, but, in the case the last luminance is not low, the AF operation is unnecessary, then, such the operation is not performed. In the case, the externally attached stroboscopic device is loaded, the focusing detecting operation is performed with the externally attached auxiliary light having the pattern projection in the case the luminange is low (106). In the case, the luminance is not low, in addition to this operation, in the case, the contrast is low, the focus detecting operation is performed with the externally attached auxiliary light (108), in the case, the contrast is not low, the focus detecting operation with the auxiliary light is not necessary, then, such the operation is not performed.

Abstract: PURPOSE:To prevent the generation of deterimental defect of operation by providing a gate circuit between an encoder having split low-order bits and an encoder at the next stage so as to prevent outputs of plural subordinate encoders from being turned on at the same time. CONSTITUTION:An output of the 1st encoder having split low-order bits is connected to an input 1, an output of the 2nd encoder having split low-order bits is connected to an input 2, and respective outputs 1, 2 of logical circuits 8A', 8B' are inputted to a host encoder. Provided that active data is inputted to inputs 1, 2 at the same time, its control output 0 is applied to a gate circuit 9 from an NOR circuit 10A. Thus, a gate circuit 9 does not transfer the data of the input 2 to the output 2 and only the data of the input 1 is generaged at the output 1. Thus, a large error affecting plural encoders having low-order bits is not generated.

Abstract: PURPOSE:To feed the contact medium of high viscosity by arranging a contact medium storing vessel and a feeding pump in the titled device. CONSTITUTION:Rotation of a scanning driving motor 6 rotates a pulley 8 through a decelerator 7. A pin 9 is fixed on a pulley 8 and one end of a coupling rod 10 is pivotally coupled with the pin 9. A pinion gear 11 engaged with a rack part on the other end is positivity/negatively rotated by the reciprocation of the coupling rod 10 and the movement slides a sliding rod 3 linearly through a gear 5 to slide a probe 1 in the (x) direction. The rotation of the pulley 8 is transmitted to a pulley 13 through a timing belt 14 to drive a pump 15 directly coupled with the pulley 13. Thereby, the scanning speed of the probe 1 is changed in proportion to the rotational speed of the motor 6 and the capacity of the pump 15 is changed.
