Title: Production of aromatic compound
Inventor: HATA HIROYUKI
IPC: C07C49/84
Filed: 1990-04-26
Abstract: PURPOSE:To carry out the acylation or alkylation reaction of an aromatic compound with industrial advantages such as free from the safety problems and the easy post-treatment of the reaction product by using trichlorobenzene as a reaction solvent. CONSTITUTION:A compound having an aromatic ring, preferably a compound having phenyl group is acylated or alkylated by Friedel Crafts reaction using preferably aluminum chloride as a catalyst, In the above reaction, trichlorobenzene is used as a reaction solvent in place of conventional halogenated hydrocarbon solvent. The above reaction can be safely carried out without causing the problems of carcinogenicity and destruction of ozonosphere. Furthermore, the formation of emulsion inevitable in the use of the above conventional solvent can be eliminated to enable the quick separation of the water layer from the organic layer and facilitate the post-treatment of the reaction liquid.

Title: Adaptive pi control system
Inventor: TORII NOBUTOSHI
IPC: G05D3/12
Filed: 1991-04-16
Abstract: PURPOSE:To enable robust control by bringing a speed loop under PI control through the control of a system which greatly varies in the inertia of a robot, etc. CONSTITUTION:An adder 1 subtracts a speed Y from a speed command and its output is sent to the element 2 consisting of a proportional gain term and an integral gain term. An element 3 multiplies the result of the element 2 by a plant parameter Gp by a control rule and an adaption rule. An estimated plant parameter K1p of the integral gain is found from the speed Y of a servo motor 5 and an estimated error epsilon and the speed Y is multiplied by the estimated plant parameter K1p. Those terms are added by an adder 4 to find speed estimation U, which is outputted to the servo motor 5. Those elements 2, 3, and 6, and the adder 4 constitute the reverse system of a normative model and the servo motor 5, and consequently even if the inertia varies, the robust control is enabled.

Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily extract a character to be inputted by extending a recognition retrieval range for a featured value in a character recognition means when a user instructs rerecognition and executing rerecognition. SOLUTION: When ink data are inputted to an ink data input column 3, a character recognition part 6 executes character recognition processing for the ink data. One or plural candidate characters extracted as a character recognition processing result are displayed on a 1st recognition caracter display column. When a character different from a character to be inputted is displayed as a candidate character, an input device 4 selects the misrecognized character and displays some candidate characters on a 2nd recognition character display column together with the original ink data. When the ink data are selected, a retrieving range for the ink data is extended to execute rerecognition processing. A recognized result is substituted for the misrecognized character displayed on the display column 2.

Abstract: PROBLEM TO BE SOLVED: To reduce the magnetomotive force loss of an induction motor, and to enhance the starting efficiency of the rotor by causing a rotor core to have a plurality of spaces divided by core legs around shaft-inserting hole formed in the central part of the rotor core. SOLUTION: A rotor 10 has a shaft-inserting hole 13 to be jointed to a motor shaft 11 at the center of the rotor core 12, and with the shaft-inserting hole 13 as the center, a plurality of core legs 14 are formed radially, and spaces 15 are formed between the core legs 14. The core legs 14 are formed into identical shape on both sides of the rotor core 12 respectively, and the spaces 15 are also formed at the same positions symmetrically, and the spaces 15 on both sides are clogged up by a screen board 18. Consequently, the distance for magnetic flux to pass is shortened, and the loss of a magnetomotive force can be reduced. Accordingly, it becomes possible to raise the starting efficiency of the motor.  Besides, it becomes possible to reduce the no-load torque and the inertial force, since the weight of the rotor 10 is reduced by the spaces, and it is possible to reduce the manufacturing cost as well, by curtailment of rotor core 12 materials.

Title: Method for forming multiple image
Inventor: SERIZAWA YOJI
IPC: G03G15/01
Filed: 1987-05-07
Abstract: PURPOSE:To allow the writing start position of an image to simplify coincide without being affected by the difference between the quantities of respective laser beams and to enhance image quality, by determining the modulation start point of time by detecting the deflecting positions of the first and second layer beams on the basis of different reference values corresponding to the quantities of the first and second beams. CONSTITUTION:The laser beams 2, 3 emitted from semiconductive lasers 11, 12 are deflected in the axial direction of a photosensitive drum 1 by a rotary polyhedral mirror 13 and incident to the photodiodes 18, 19 placed at the same distance from the surface of the photosensitive drum 1. These laser beams 2, 3 are sliced by wave form shaping circuits 22, 23 so that large and small reference potentials VS1, VS2 respectively matched with the strong and weak intensities of the laser beams are set to threshold values to form rectangular signals which are, in turn, outputted as synchronous signals determining the start of beam modulation. By this method, the rising timings of the pulse wave forms after wave form shaping can be allowed to coincide. Therefore, the first and second writing start positions of an image can be allowed to coincide with each other and the deterioration of image quality can be prevented.
