Abstract: PURPOSE:To obtain a high-speed, high-reliability microprocessor system by detecting and correcting a memory error by utilizing a free time after an instruction or data is read out of a memory by a microprocessor. CONSTITUTION:A memory address generating circuit 6 has a counter circuit which counts up by one automatically and its output signal is supplied to the memory 22 through an AND gate 7 and an OR gate 3 by memory access signal 20 under the control of an NOT gate 21. The resulting read data from the memory 22 is supplied to an error detecting circuit 8 to check a humming code, and a correctable error is obtained to output an correctable error signal 9. Error data is then inputted to an error correcting circuit 12 to correct a one- bit error. The memory address generating an error is inputted to and stored in an error address register circuit 13 through an AND gate 10 and corrected data is inputted to and stored in a corrected data register circuit 14 through an AND gate 11.

Title: Method for releasing nitro or amino group bonding to aromatic ring
Inventor: MINOJIMA TORU
IPC: C25B3/25
Filed: 1994-03-04
Abstract: PURPOSE:To easily release a nitro or amino group and to restore the group to a hydrogen atom by electrolytically reducing a compd. having a nitro or amino group bonding to an arom. ring having a specified number of carbon atoms in a solvent. contg. an aq. nitric acid soln. CONSTITUTION:An arom. compd. represented by the formula Ar-NY (where Ar is a 6-10C arom. ring which may have a substituent and NY is a nitro or amino group) is electrolytically reduced in a solvent contg. an aq. nitric acid soln. Since NY bonding to Ar is easily released by this method, a nitro or amino group can be used as a dummy for hydrogen on an arom. ring. When a substituent is introduced into an arom. ring having some reactive positions, positions at which a reaction is not allowed are previously nitrated and a substitution reaction is allowed to take place only at a position at which a nitro group does not exist. After the end of the reaction, nitro groups are restored to hydrogen atoms. Thus, the substitution reaction can be attained with positional selectivity.

Title: Grinding method for gear
Inventor: KATO SHOGO
IPC: B23F5/02
Filed: 1988-02-17
Abstract: PURPOSE:To improve the life of a grinding tool and to reduce the required grinding time by relatively moving a grinding tool by the distance equal to cumulative deviation which is the total value of deviations from a grinding start tooth to the respective specified teeth. CONSTITUTION:At the time of measuring tooth pitch by a device 60 before grinding is started, a computer 44 calculates cumulative deviation data on a tooth with the minimum pitch to the respective teeth according to rotating position data of a stored ground gear 12 and a measuring gear 62. Simultaneously, target rotating speed data of a servo motor 26 is computed in such a manner that a specified portion of a grinding tooth 34 is relatively moved from the normal relative position with respect to a specified tooth of the gear 12 in the rotating direction Y by the distance equal to a cumulative error. After grinding is started, the target rotating speed data corresponding to the present rotating position of the gear 12 is supplied to the servo motor 26 through an amplifier 50. Thus, machining allowances before and after each tooth of the gear 12 are equal to each other, so that the tooth form can be ground to the normal form in a short time and lowering of life of a grinding tool can be prevented.

Abstract: PURPOSE:To prevent counter transfer of paint from a form to an ink film, by providing a platen roller, for pressing an overlapped ink film paper arranged in correspondence with a head for applying heat corresponding to a signal, and a counter transfer preventing means for pressing the ink film to the paper side. CONSTITUTION:After an ink film 27 and a paper 25 are moved in the direction of an arrow B and applied with heat by means of a head 19, they are separated at point A. When the separating point (point A) of the ink film 27 and the paper 25 is moved further in printing direction than a printing point of the head 19 through a counter transfer preventing means 30, temperature at the separating point lowers, thereby paint applied onto the ink film 27 is solidified and transferred completely to the paper 25. When the position of point A is varied, difference of paint in the ink film can be absorbed.

Title: Decentralized processing system of information
Inventor: KIKUMOTO MASAHIRO
IPC: G06F17/30
Filed: 1982-03-08
Abstract: PURPOSE:To lower the occupying factor of circuit and to improve the processing capacity of an information processing system consisting of a controller and plural input/output devices, by storing previously the information having high using frequencies dispersedly even to the input/output devices. CONSTITUTION:A controller 1 is connected to plural input/output devices 3 via a communication circuit 2. The controller 1 registers the data of all information and their indexes to a table 10 together with the addresses of information which are decentralized to the input/output devices 3. Each device 3 has a table 20 which stores the information of a high using frequency along with its address in response to the property and the type of the device. The controller 1 decides the necessity for transmission of information and transmits only necessary information to each device 3. Thus the device 3 receives only its lacking information from the controller 1. This process lowers the occupying factor of a circuit and improves the processing capacity of a system as a whole.

Abstract: PURPOSE:To improve volumetric efficiency by removing residual refrigerant gas completely and also by increasing a sucking amount of the refrigerant gas through such a means and the like that a discharge passage for discharging residual refrigerant gas existing in a compression chamber to another compression chamber, is formed in a rotary valve. CONSTITUTION:In a rocking swash plate type compressor, rotary motion of a rotary shaft 4 is converted to backward and forward reciprocating rock motion of a rocking swash plate 9 through a rotary holder 5 and a rotary driver 6. Thus, pistons 10A move forwards and backwards in cylinder bores 1a. In this case, a suction port 1c of a compression chamber R is connected to a suction passage 17 of a rotary valve 14 synchronizing with the reciprocating motion of the pistons 10A. Furthermore, residual refrigerant gas in one of the compression chambers R is discharged to one of other compression chambers R by forming a discharge passage in the rotary valve 14. In addition, width of an inlet 18a of the discharge passage in the peripheral direction of the rotary valve 14 is made narrower than the width of a suction port 1c. The period of connecting the compression chamber R to the inlet 18a of the discharge passage is set so as to include the position of the upper dead point of the piston 10A.
