IPC: B03C3/68
Filed: 1994-04-08
Abstract: PURPOSE:To provide a safe air cleaner capable of surely conducting deodorization and sterilization by making the amt. of generated ozone controllable. CONSTITUTION:The ozone concn. in the air is always detected by an ozone sensor 8, and the detection value is transmitted to a voltage control circuit 2. When the detection value is higher than the preset reference value, the high voltage generating circuit 2 is controlled so that the voltage to be impressed on a discharge electrode 3 and a dust collecting electrode 4 by the voltage control circuit 2 is lowered, and the amt. of ozone generated by an electric discharge is reduced. Meanwhile, when the detection value is lower than the reference value, the high voltage generating circuit 2 is controlled so that the voltage to be impressed on both electrodes 3 and 4 by the voltage control circuit 2 is increased, and the amt. of ozone generated by the electric discharge is increased.

Filed: 1990-03-20
Abstract: PURPOSE:To improve the mixing and electrification importing properties of a developer and the quality of an image by providing a major axis part where a distance from the center of a rotary shaft is set at a prescribed value, and a minor axis part where the distance from the center of the rotary shaft is set at a value shorter than the prescribed one, on the spiral blade of a developer carrying member, on a face perpendicular to a developer carrying direction. CONSTITUTION:The rotary shaft 31 of the developer carrying member 3 is eccentrically pro vided, the spiral blade 5 of the developer carrying member 3 has the major axis part 51 where the distance from the center of the rotary shaft 31 is set to the prescribed value and the minor axis part 52 where the distance from the center of the rotary shaft 31 is set at the value shorter than the prescribed one on the face perpendicular to the developer carrying direction. Therefore, the developer inside the developer carrying path 9 is carrying in a state where the developer is biased to the side of the major axis part 51 compared with the side of the minor axis part 52 of the spiral blade 5 by the rotation of the developer carrying member 3, and the quantity of the developer in the vicinity of a sidewall surface is reduced according to the passing through the major axis part 51. When the minor axis part faces to the sidewall surface, the developer in the upper part drops the bottom surface side of the lower part through a gap formed between the minor axis part and the sidewall surface, and is mixed with the developer of the lower part. Thus, the mixing and the electrifica tion imparting properties of the developer and the quality of the image are improved.

Filed: 1994-04-11
Abstract: PURPOSE:To detect the presence of a disk safely before the irradiation of a laser by detecting the presence of the disk with a frequency level locked by a PLL circuit by a disk detection means. CONSTITUTION:When a CD disk 1 is loaded on a disk base 2, and a cover is closed, a control means 7 supplies power to a spindle motor 3 through a driver 9 to rotate the motor 3. Then, when no disk 1 is loaded, and the cover is closed, though the control means 7 supplies the power to the spindle motor 3 through the driver 9 to rotate it, the motor 3 rotates at high speed since no disk 1 is loaded, and a rotation sensor 4 detects a signal showing a high rotational speed to input it to the PLL circuit 6 and the disk detection means 8a. The detection means 8a compares the rotational speed of the spindle motor 3 with the frequency stored in a table 8b, and decides that no disk 1 exists since the rotational speed of the motor 3 is higher than the frequency, and reports no disk 1 exists to the control means 7, and stops the rotation of the motor 3 through the driver 9 to return to a stand-by state.

Title: Gas analyzer
Inventor: AOKI JIYUNJI
IPC: G01N21/27
Filed: 1984-04-10
Abstract: PURPOSE:To enable elimination of the deviation in the central wavelength of an interference filter from the demanded wavelength even if such deviation arises by providing a slit between the interference filter and a detector and making variable the distance between the slit and the detector. CONSTITUTION:The light emitted from a light source 1 is reflected by the specular surface on the inside surface of a cell 2 and is throttled by the slit 6 by which the light is made incident on the photodetecting surface of the detector 3 at the angle shown in the figure. If the detector 3 is moved along the optical path in this case, the distance between the detector and the slit 6 changes and therefore the incident angle of the light on a multilayered film interference filter 5 changes. More specifically, the incident angle increases as shown by the figure (a) when the detector 3 approaches to the slit 6 and the incident angle decreases as shown in the figure (b) when the detector receses from the slit. The central wavelength of the multi-layered film interference filter changes with the change in the incident angle and therefore even if the central wavelength of the filter 6 deviates from the desired wavelength, the deviation of the central wavelength is eliminated by moving the detector in the above-mentioned way.
