Title: Production of suberonitrile
Inventor: NANBA HIROYUKI
IPC: C07B61/00
Filed: 1987-02-12
Abstract: PURPOSE:To obtain the titled compound useful as a synthetic intermediate for agricultural chemicals, pharmaceuticals, dicarboxylic acid, diamine, etc., in high yield, reducing the cost for waste water treatment, by reacting 1,6- dichlorohexane with an aqueous solution of sodium cyanide in the presence of a phase-transfer catalyst. CONSTITUTION:The objective compound can be produced by reacting 1,6- dichlorohexane with an aqueous solution of sodium cyanide in the presence of a phase-transfer catalyst of formula (R1-R4 are 3-10C alkyl) (e.g. tetraalkylammonium bromide). The reaction is carried out by introducing 1,6- dichlorohexane and the catalyst into the first stage of a plurality of serially disposed reactors, separating the reaction liquid in the latter stage reactor into an oil layer and a water layer after the completion of the reaction and returning the aqueous solution containing unreacted sodium cyanide to the first stage reactor to effect the reaction. The reaction is performed by keeping the reaction temperature of each reactor at 80-140 deg.C for 0.5-8hr, preferably at 90-110 deg.C for 2-4hr. Since the residual CN ion in the waste water is decreased, the cost for waste water treatment can be reduced.

Title: Image forming device
Inventor: TSUCHIDA HITOSHI
IPC: H04N1/04
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which precisely corrects the scanning direction of an optical scanning means and the parallel degree of a photoreceptor rotary shaft in short time. SOLUTION: Initial scanning is started from a mark A1. A1, A2, A3 and A4 are intermediate scanning positions. The corner part of an image frame 3-B is detected as one point in the scanning position A2 and Bsecθ is detected against image width B from the scanning position A3 to A4. Namely, a black signal of image detection is not generated until a system proceeds to the scanning position A2 from time when scanning starts and only a white signal exists, for example. When the system proceeds to the scanning position A2, the corner part of the image frame 3-B is detected and the black signal is generated one by one. The scanning results are compared with the normal posture of an image area which is previously stored, and the detected inclination of the image area is operated.  Thus, the moving amount of optical scanning for correcting the deviation of the parallel degree in the photoreceptor rotary shaft can precisely be obtained in short time.

Title: Method and device for packaging electronic parts
Inventor: NAI YASUTO
IPC: H05K3/34
Filed: 1994-02-25
Abstract: PURPOSE:To improve efficiency and Joint quality when joining the leads of electronic parts by stopping the joint of all leads of electronic parts when the number of accumulated faulty blocks is equal to or more than a prescribed value and by preventing joint for the leads contained in the faulty block if the number is equal to or less than the prescribed value. CONSTITUTION:The contact state between a lead and a pad, namely the presence or absence of lead lifting, is detected by an infrared ray detector 20 and a waveform analyzer 21. A central control device 22 receives the information on the presence or absence of the lead lifting sent from the waveform analyzer 21. When the number of accumulated faulty visual fields exceeds a certain prescribed value, the joint of the target parts is stopped based on the inspection result. When the number is equal to or less than the prescribed value, only the blocks of faulty visual fields are skipped without any joint and four sides are joined successively, thus improving the efficiency and joint quality when joining the leads of the electronic parts.

Abstract: PURPOSE:To retard the hardening of stuck mixture and eliminate the need for cleaning operation of the mixture stuck in a mixing device for radioactive waste and thermosetting resins, by cooling the mixer and discharge valve in said mixing device. CONSTITUTION:In solidifying radioactive waste and thermosetting resins, a device connecting a mixer 1 and a discharge valve 5 by means of a flange 4 is used. Radioactive waste, thermosetting resins, polymerization accelerators and polymerization initiators are added through inlets 12, 13, 14, 15 into the mixer 1, then a revolving shaft 17 is revolved and the abovementioned additives are stirred and mixed by stirring vanes 18. The mixture is discharged through a discharge port 6 into a vessel 20 by opening a discharge valve 5, and is allowed to polymerize and solidify. At this time, the mixer body 3 and the discharge valve 5 are cooled with a refrigerant so that the polymerizing and setting of the mixture stuck on their inside parts are retarded and the setting is prolonged until the commencement of the next mixing operation, thence this stuck mixture is discharged together with the next mixture. The need for the operation of removing the stuck matter by the special cleaning for the stuck matter only is eliminated.

Title: Device and method for photographed image retrieval
Inventor: IIJIMA JUN
IPC: H04N5/76
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a photographed image retrieval device and photographed image retrieval method, where a recorded photographed image is retrieved by using photographing condition and/or an image evaluation condition for a reference. SOLUTION: A photographing condition, importance (= image evaluation level) and usage frequency of a recorded image are evaluated as a numeral and the result is registered, in cross reference with an image number. At retrieval, a retrieval instruction image is displayed and designated by the use of the photographing condition, importance and frequency of use for a retrieval condition, and the registered photographing condition, importance and frequency of use are searched, and an image having the matching conditions is extracted and displayed sequentially. Thus, an image photographed under a photographing condition is simply selected.  For example, in the case that an image photographed with strobe is retrieved and the image is selected depending on its photographed quality, the image is simply and quickly selected more than a conventional method where images are reproduced in the photographed order and strobe photographed images are selected. Since the photographing condition is automatically registered at photographing, also no entry of a key word is required.
