Title: Production of 1,1,1,2-tetrafluoroethane
Inventor: KOBAYASHI TSUTOMU
IPC: C07C19/08
Filed: 1990-03-09
Abstract: PURPOSE:To obtain the subject substance useful as a refrigerant in an excellent conversion and selectivity by rearranging 1,1,2,2-tetrafluoroethane in the presence of HF using a chromium (III) oxide catalyst pretreated with HF. CONSTITUTION:The subject substance is obtained by using 1,1,2,2- tetrafluoroethane and HF in [1:(0.2-10)] molar ratio and rearranging the former compound in the presence of a chromium (III) oxide catalyst pretreated with HF at 300-400 deg.C (preferably 320-380 deg.C). The reaction pressure is preferably the ordinary pressure-10kg/cm<2> and the contact time W/F (W is weight of catalyst; F is flow rate of gas at standard state) is preferably 1-100g.sec/cc. The above-mentioned method has the following merits; No expensive raw material is required. The amount of HF used is low. The catalytic life is long. Deterioration of the chromium catalyst can remarkably be prevented by coexistence of HF.

IPC: G06T1/00
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To further improve image quality by enabling required correction, even for a dot for which the correction as a contour line is not nuded is discriminated. SOLUTION: Image data expanded in the form of bit map are extracted through a window 73 and for the attention dot at its center, the form of line segment at the border part of black and white dot areas is recognized by a pattern-recognition part 74 and replaced with the code information of plural bits. While utilizing that code information, it is discriminated whether the dot requires correction or not and concerning the correction required dot, the correction is performed by reading the correction data corresponding to this code information out of a memory block 75.  In the image data expanded in the form of bit map, an edge-discriminating means 78 discriminates whether each black dot is a right end dot, a left end dot, an isolated dot or any other dot in the main scanning direction of the image data and according to the discriminated result, and then one part of correction data is determined.

Filed: 1981-04-23
Abstract: PURPOSE: To obtain a vitamin-enriched food and drink with a slight reduction in the vitaminic content by the processing, by adding a clathrate compound of a vitamin with cyclodextrin to the food and drink.  
     CONSTITUTION: A clathrate compound obtained by reacting a vitamin, optionally any of the three forms of α, β and γ or a mixture thereof, with cyclodextrin is added to a raw material for a food and drink, preferably a processed food, e.g. fermented soybean, yogurt, lactic beverage, pickles, MISO or soy sauce, heated in the preparing process, and concerned with a microorganism to prepare the processed food. Thus, the vitamin lost during the preparation is slight, and further of course the inactivation during the storage after the preparation is slight. The processed food having improved vitamin enriching effect can be obtained. The clathrate compound may be added after the preparation of course; however, the inclusion in the cyclodextrin renders the vitamin readily soluble in water. Therefore, the clathrate compound can be uniformly mixed in any step.

Abstract: PROBLEM TO BE SOLVED: To provide a display element by an active matrix drive preventing malfunction of a driving thin film transistor while enhancing light-using rate to the maximum by making a gap from a semiconductor layer to an electrode layer just above a gate electrode a specified value or below and driving with a drive voltage of a specified value or above. SOLUTION: The thin film transistor(TFT) contains a source electrode 11 and a drain electrode 10 formed on one side substrate 4 and the gate electrode 8 arranged above a channel area formed by the source electrode 11 and the drain electrode 10. Then, the gap from the channel area to the electrode layer just above the gate electrode 8 is 2μm, and it is driven by the drive voltage of 10V or above. In such a case, by an electrostatic shield effect, an electric field distribution between the channel area and the gate electrode 8 is provided only by the potential of the gate electrode 8, and isn't affected by the electric field distribution of the outside of it. Thus, the malfunction of the TFT is evaded event when a display electrode group is set up so as to cover the whole TFT.

Title: Pattern inspection apparatus
Inventor: ANDO MORITOSHI
IPC: H05K13/08
Filed: 1987-03-18
Abstract: PURPOSE:To increase an inspection speed and to enhance image resolving power, by controlling the light accumulation times of two-dimensional CCD sensors by a light shutter and alternately changing over said sensors to detect an image. CONSTITUTION:The light shutters of two-dimensional CCD sensors 11, 12 are alternately turned ON and OFF by light shutter control parts 13, 14 and each of the ON-times thereof is set, for example, to 1/60sec, i.e. on half of a frame time. An image change-over part 15 alternately changes over the light cut images from the sensors 11, 12 at every 1/60sec in synchronous relation to the operation of the light shutters to take out said images and feeds the same to a height detection part 17. The height images of the respective fed images are calculated by the detection part 17 to obtain a three-dimensional image. This three-dimensional image is compared with a reference image by an image discrimination part 18 to make it possible to know the positional shift of a part or the omission of the part. By this method, a light accumulation time peer frame can be shortened to 1/60sec and, since the ON-states do not overlap with each other, the fog or flow of left and right images is not generated. Therefore, an increase in an inspection speed and the enhancement of image resolving power can be realized.

Abstract: PURPOSE:To surely detect the rotation of a body of rotation independently of the rotation of a motor by providing the titled device with a deciding means for deciding the existence/rotating state of the body of rotation on the basis of an output from a rotation detecting means at the generation of driving force from a driving force generating means. CONSTITUTION:A coupling member 15 is constituted so as to be rotated in accordance with the rotation of the rotary body 41. In case the body of rotation 41 is mounted, a driving force generating means generates driving force, and at the rotation of the body of rotation 41, the coupling member 15 is also rotated. As the result, the detecting means 17 generates an output indicating the rotation of the body of rotation 41 and the deciding means 18 generates an output indicating the execution of normal operation. In case the body of rotation 41 is not mounted or in case abnormal state such as a failure in a rotary body driving system including the driving force generating means 10 is generated, no output is generated from the means 17 and the deciding means 18 generates an output indicating abnormality. Thereby, the rotating operation of the body of rotation can be surely detected without misdetection.

Abstract: PURPOSE:To suppress the generation of the peak of an attracting force by precedingly rising a slip frequency prior to a voltage pattern at the time of thrust force rise, and precedingly falling a voltage pattern prior to the slip frequency at the time of thrust force fall. CONSTITUTION:When a power drive command 21 becomes ON, a primary delay calculator 28 applies a signal gradually rising to the set value of a current limiting value setter 22 according to a time constant tau to a slip frequency calculator 30.
