Title: Pick-up device
Inventor: KURATA YUKIO
IPC: G11B7/135
Filed: 1985-11-11
Abstract: PURPOSE:To have the symmetric property, to minimize the number of parts, to be small-sized and light-weight and to execute the low-price as much as possible by arranging the diffraction grating between the light source and the focusing lens, dividing the return light from the recording support with the diffraction grating and guiding it to the light detecting device. CONSTITUTION:After the light to emit from a semiconductor laser 7 is collimat ed by a collimator lens 4 and transmits a diffraction grating 3, a zero-order light proceeds in the direction orthogonal to a recording surface 1a of a record ing support 1, collected by an objective lens 2 and irradiated on the recording surface 1a. The irradiated light, after the light is modulated at the recording information part on the recording support 1 and focused by the objective lens 2, is diffracted by the diffraction grating 3. The light diffracted by the diffrac tion grating 3 is focused on detecting devices 6a and 6b and the information on the recording support 1 can be reproduced. Thus, the symmetric property of the pick-up can be realized and the device can be made smaller-sized, light- weight and low-priced.

Abstract: PURPOSE:To decompose org. matters in service water efficiently in an apparatus for treating service water with ozone by housing a noncarbon filter medium bed and a carbon filter medium bed in a filtration tank and connecting an ozone feeding pipe with a service water pipe. CONSTITUTION:During a stage for feeding service water to a filtration tank 20 through a service water pipe 1, ozone is fed as bubbles through an ozone feeding pipe 3 to the service water. A part of the ozone contacts with org. matters contained in the service water and decomposes the org. matters by the effect of oxidizing power of ozone. The ozone dissolved in the service water contacts with org. matters in a duct ranging from a carbon filter medium bed 4 to a noncarbon filter medium bed 5. Org. matters having contacted with the carbon filter medium bed are adsorbed and decompose ozone. Adsorbed org. matters are decomposed by nascent oxygen generated by the decomposition of ozone. Thus, service water is treated with ozone in a short time.

Abstract: PROBLEM TO BE SOLVED: To obtain a stable potential by electrification and image, regardless of environmental changes and changes with time, with an inexpensive constitution by setting a DC voltage applied to an electrifying member, based on the output of a photosensor for detecting the reflection density of the surface of a photoreceptor. SOLUTION: This image forming device is provided with a voltage applying means for applying the DC voltage to the electrifying member 2, the photosensor 10 for detecting the reflection density of the surface of the photoreceptor 1 and a voltage control means for changing the DC voltage applied to the electrifying member 2, in a nonimage forming region and setting the DC voltage applied to the electrifying member 2, in accordance with the output ratio of the photosensor 10 before and after the change. Thus, surface density (at reversal development) by a potential by the electrification or image density (at normal development) is directly detected by the photosensor 10.  Further, a developing means is of a reversal developing system one and the voltage control means sets the DC voltage applied to the electrifying member 2, at which the output ratio of the photosensor 10 is set within a fixed range. Thus, surface staining caused by the decrease of a voltage at the time of attaining the reversal development can be surely prevented.

Title: Character recognizing device
Inventor: KITAGAWA KIYOSHI
IPC: G06K9/32
Filed: 1989-09-30
Abstract: PURPOSE:To enable correct recognition even when a sheet is inclined, and to improve speed for a recognition processing by executing the character recognition after a character string for one inclined line is corrected to a normal character string. CONSTITUTION:The data of character images read from an image input part 2 are stored in a picture memory 3. Next, when the data of the character images are read out from the memory 3, based on the amount of inclination for the sheet detected by a skew detecting means 1, the respective data of the character string for one skewed line are rotated by a skew converting means 4 and read out so as to obtain a normal state. Then, the data are stored in a buffer memory 5. As a result, the data are stored memory 5 in the same state as the data of a character string for one line read in a state that the sheet is not inclined. Accordingly, since a character recognizing means 6 executes the recognition processing to the data of the character string for one line under the normal state, the rate of the recognition is improved and the speed for the recognition processing is also improved.
