Title: Picture processor
Inventor: MATSUDA RYUICHI
IPC: G06T9/20
Filed: 1994-01-18
Abstract: PURPOSE:To speedily and accurately extract the required picture edge from among multilevel picture data by detecting the picture data in the section data range and performing the differential processing on the data. CONSTITUTION:The picture data taken through a camera 1 and a picture memory 2 are taken in a calculation part 4 and a comparator 5. The comparator 5 compares it with the section data of a setting part 3. It gives a calculation command to the part 4 only when the picture data between the upper and lower limit values of the section data is detected. The differential processing detecting the density grade of the picture data is performed in the part 4. Thus, the section data range where few noise component is detected is set and the pre-processing to be performed before the differential processing is not required by detecting the data in the range and no noise component is detected.

Inventor: SASAKI TAEMI
IPC: B01J49/00
Filed: 1992-01-13
Abstract: PURPOSE:To decrease the organic impurities eluted from the ion exchange resin in a condensing and desalting tower by using the gas (nitrogen gas, inactive gas or the like), which does not contain oxygen in backwash regeneration. CONSTITUTION:Solid matter is attached to the layer of a granular ion exchange resin 1 filled in a condensing and desalting tower 2. The resin, on which pressure difference between an inlet port and an outlet port exceeds the specified value, is sent into a cation-exchange-resin regenerating tower 6. Nitrogen gas is injected from a nitrogen cylinder 15 into the lower parts of the regenerating tower 6. The resin 1 is agitated with the nitrogen gas and water. The solid matter, which is separated from the resin 1, is drain from the bottom of the regenerating tower 6 and discharged through an overflow pipe 9 together with backwash water. The resin is backwashed and separated into cation and anion exchange resins. The separated respective resins are sent into the regenerating towers 6 and 7 and backwashed and regenerated with the nitrogen gas and the water. The regenerated resin is sent into a resin storing tank 8 and mixed in the tank. The resin in the mixed state is returned into the desalting tower 2. The gas, which does not contain oxygen, is used in backwash and regeneration. Thus, the elution of the organic material from the ion exchange resin is decreased.

IPC: G01N21/88
Filed: 1988-01-12
Abstract: In a scanner for the optical checking of objects such as CD-discs there is provided a coherent light source; a light deflecting device which allows a light beam emitted from the light source to sweep over the object in a substantially linear scanning movement, with the optical axis of the light beam subtending a small angle with a normal to the object surface transverse to the scanning direction; and a detector for detecting light which is reflected back from the object. In the present arrangement the optical axis of the light beam also subtends a small angle with the normal to the object surface in the scanning direction. This makes it possible to avoid disturbing modulation of the detector signal due to interference effects.

Filed: 1987-01-12
Abstract: PURPOSE:To improve the frequency temperature characteristic remarkably by generating a compensation voltage based on a heater voltage change for temperature control of a cavity resonator due to external temperature change and superimposing the voltage onto a C field coil current generation setting voltage. CONSTITUTION:A heater voltage is detected by a temperature detection means 6. The voltage detected by the temperature detection means 6 is fed to a compensation voltage generating means 7 and converted into a voltage compensating the frequency change due to temperature change. A C field current control means 5 adjusts the C field current and the static magnetic field to apply minute adjustment of the frequency at the standard temperature. An adder means 8 adds the reference voltage set by the minute adjustment with the compensation voltage generated by the means 7. The added voltage is fed to the C field current control means 5. The C field current is changed by the compensation voltage given superimposingly to cause the frequency change. The frequency temperature characteristic is improved remarkably by generating the compensation voltage to cancel the frequency change due to temperature change.
