Filed: 1980-09-10
Abstract: PURPOSE: To prepare the titled compound useful as an intermediate of antiphlogistic agent, analgesic agent, etc., easily, in high yield, at an extremely low cost, by using a benzylidene derivative derived from o-phthalaldehydic acid and an aniline derivative as a raw material, and cyclizing the compound with a reducing agent.  
     CONSTITUTION: The benzylidene derivative of formula I (R is H or 1W2C lower alkyl; X is carboxy, carboalkoxy, amido, or cyano) is used as a raw material, and is cyclized with a reducing agent (e.g. sodium borohydride, potassium borohydride, etc.) to obtain the isoindoline derivative of formula II. As a alternative method, the compound of formula II can be obtained by the one-bath reaction comprising the reaction of the o-phthalaldehydic acid of formula III with the aniline derivative of formula IV, and the cyclization of the resultant intermediate of formula I in the reaction mixture, in a similar manner to the above reaction. The compound of formula II can be converted easily to indoprofen (an antiphlogistic agent and an analgesic agent) by hydrolysis.

IPC: G06K9/32
Filed: 1995-05-26
Abstract: PURPOSE: To detect the inclination of a document image in a short time by rotating scanning lines around the shortest character/graphic picture element and detecting a maximum angle at which no character/graphic picture element is detected on scanning lines in a circumscribed rectangle. CONSTITUTION: A partial picture storage part 12 stores a partial picture including a corner space block and a corner character/graphic block of a document to be processed. An inclination candidate detecting part 14 detects a circumscribed rectangle circumscribing the corner character/graphic block from the stored partial picture.

Then the detecting part 14 rotates scanning lines around the character/graphic picture element which is located at a distance shortest from a position parallel with the noticed side and detects the maximum rotational angle that no character/graphic picture element is detected on the scanning lines in the circumscribed rectangle. An inclination detecting part 16 detects the average value of character picture inclination candidates as the inclination of the document image.

Filed: 1980-09-17
Abstract: PURPOSE: To disperse the fine particle additive uniformly in the plating liquid without using the dispersant by giving supersonic vibration to the composite plating liquid containing the fine particle additive.  
     CONSTITUTION: The fine particle 1 is apt to precipitate on the bottom 6a of the plating bath 6, because the dispersant is not mixed in the composite plating liquid 3 containing the fine particle additive 1 of oxide, carbide, metal etc. This plating liquid 3 is drawn by the pump 8 and sent to the dispersion bath 4 and supersonic vibration is given by the supersonic oscillator 5. By this, it becomes a milky white plating liquid 3 dispersed with the fine particle 1 and, it is returned through the hose 9 to the upper part 6b of the plating bath 6. The fine particles are dispersed to the whole plating liquid 3 by this circulation and the composite plating layer dispersed with the fine particle 1 of ceramics etc. is formed on a plated object.

IPC: G06F1/26
Filed: 1985-06-13
Abstract: PURPOSE:To prevent a malfunction at the application of a power supply by providing a power supply control signal between a call indication CI receiving circuit part and a power supply control line. CONSTITUTION:The power supply application signal is sent to a power supply control circuit 5 from a live adaptor 3 with incoming of a CI signal. Thus the circuit 5 is set under a power supply application sequence state and applies a main power supply 6, etc. When the supply 6 is applied, both a CPU 1 and a line adaptor 3 come wholly to a conductive state and the signals ER, etc. can be sent back to a circuit interface. At the same time, a register 8 is set. In case the register 8 is not reset by the software of the CPU 1 within the prescribed period of time after execution of an IPL, the abnormality of the IPL is decided. Thus the power supply is cut off. While a protocol test process is carried out when the register 8 is reset within a fixed period. If the protocol test is abnormal, it is decided that the CI signal incoming itself has a noise malfunction or a circuit is abnormal. Then a power supply cut-off command is given from the software.
