Title: Production of 2-alkyl-4-chloro-5-hydroxymethylimidazole derivative
Inventor: NISHIDA MITSUO
IPC: C07D233/68
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To produce a high-purity 2-alkyl-4-chloro-5-hydroxymethylimidazole derivative in good yield according to an industrially simple method. SOLUTION: A 2-alkyl-5-hydroxymethylimidazole derivative is reacted with N-chlorosuccinimide in an organic solvent to provide a reactional product containing the resultant 2-alkyl-4-chloro-5-hydroxymethylimidazole derivative. The obtained reactional product is then mixed in a mixed solvent of a water- insoluble organic solvent with an acidic aqueous solution to extract the 2-alkyl-4- chloro-5-hydroxymethylimidazole derivative into the acidic aqueous solution. The acidic aqueous solution is subsequently collected by separation and by- products are then extracted and separated from the aqueous solution with an organic solvent. The resultant acidic aqueous solution is subsequently regulated to pH 4.5-9.0 with an alkali to deposit a crystal, which is separated by filtration.

Title: Method and apparatus for erasing video recording from video tape after picture recording
Inventor: NAKAJIMA SHINJI
IPC: H04N5/782
Filed: 1983-09-26
Abstract: PURPOSE:To simplify the picture recording erasure and to attain low cost by using an external video input terminal of a home use video tape recorder to apply a pseudo pulse to a vertical/horizontal synchronizing pulse thereto. CONSTITUTION:In editing a video tape after picture recording, the video tape is loaded to the home use video tape recorder for the purpose of reproduction. When the tape comes to a position where the video recording is desired to be erased while observing a picture plane, oscillators 3, 4 are operated and a pseudo pulse to the vertical synchronizing pulse and a pseudo pulse to the horizontal synchronizing pulse are transmitted to the external video input terminal 1. Then the video recording is erased from the position of the video tape while the video plane is brought into white state.

Title: Production of mottled plant
Inventor: TAGUCHI MASAYASU
IPC: A01H3/04
Filed: 1995-06-09
Abstract: PURPOSE: To provide a method for producing a mottled plant by which the mottle-patterned plant having entirely new ornamental visual effects unfound in a native mottled ornamental plant can industrially and stably be created while retaining various properties of a green leaf species plant having a higher propagation and growth ratios than those of the native mottled ornamental plant by chemically treating the plant, especially a green leaf species ornamental plant. CONSTITUTION: This method for producing a mottled plant is to carry out the spraying treatment of a leaf or a stem of a plant with a liquid mottling production treating agent comprising an insecticidal and germicidal compound capable of causing the chlorosis in the plant in its growth process and directly or indirectly destroy chlorophyll in the plant body without inhibiting the growth of the plant or inhibit the biosynthesis of the chlorophyll itself. Thereby, the artificial mottled plant having high ornamental visual effects is created by chemical treatment thereof.

Title: Data imprinting device for camera
Inventor: MATSUHASHI SHIGEO
IPC: G03B17/24
Filed: 1981-11-05
Abstract: PURPOSE:To make imprinting of data sharp by mounting a data display unit elastically to the rear cover of a camera and bringing the data display part extremely close to a photosensitive material. CONSTITUTION:A rear cover 10 of a camera has a window 15 for imprinting of data on a photosensitive material, and a recess 16 for dropping of a data display unit 20 therein.

Title: Field effect transistor
Inventor: SAKAI KIYOSHI
IPC: H01L29/78
Filed: 1987-07-17
Abstract: PURPOSE:To improve high frequency characteristics and breakdown strength by preparing an N-type island region and at the same time making the thickness of an insulating film below a gate electrode thinner than those of insulating films at other parts. CONSTITUTION:Even though an arrangement of a N-type island region 7 makes P-type regions 5 and 5' deeper, it also makes a length between N-type source regions 6 and 6' of P-type base regions 5 and 5' that result in a real channel region below a gate electrode 9 and the N-type island region 7 shorter and further, makes a part below the N-type source regions 6 and 6' of the P-type regions 5 and 5' thicker. Since the real channel region is short and lower of the N-type source regions 6 and 6' of the p-type regions 5 and 5' can be thicker, the inner resistance can be reduced to obtain favorable high frequency characteristics. Subsequently, it is difficult for a depletion layer developed from the P-type regions 5 and 5' in the N-type island region 7 but the gate electrode 9 is so located on the island region 7 that it is easy for the depletion layer to extend in the island region. Then, in addition to permitting a drain current to be taken out by passing through the P-type regions 5 and 5', the above arrangement makes it possible to perform high breakdown strengthening.

Title: Controller for injection timing of fuel of internal- combustion engine
Inventor: NAKAGAWA TOYOAKI
IPC: F02D1/18
Filed: 1981-11-09
Abstract: PURPOSE:To prevent the degradation of exhaust due to the clogging of an injection nozzle by correcting injection timing set by means of an injection timing control means mounted to an injection pump to the lead angle side only by a delay section due to clogging when detecting the clogging of the injection nozzle. CONSTITUTION:The output of the lift sensor 25 of the injection nozzle 6 is supplied to an arithmetic unit 27 as injection starting signals IS7 while voltage signals S3 responding for a period when a needle valve is lifted are outputted through a wave-form shaping circuit 86 and a pulse width counter 87. On the other hand, a reference pulse width generator 88 outputs voltage signals S4 corresponding to the lift period of the needle valve in case of normalcy from the position of an accelerator and a crank angle, and the deviation signals S5 of both signals S3, S4 are supplied to the arithmetic unit 27 from a comparator 89. Injection timing is corrected to the lead angle side in response to the signals S5 by means of the arithmetic unit 27 because the signals S5 are enlarged with the increase of the lift period of the needle valve when clogging is generated in the injection nozzle 6. Accordingly, the degradation of exhaust gas due to the delay of injection based on the clogging can be inhibited effectively.
