Title: Separation of 33and 44nitrophthalic acid mixture
Inventor: PEETAA FUURERU
IPC: C07C201/00
Filed: 1979-06-05
Abstract: A novel improved process for separating mixtures of 3- and 4-nitrophthalic acid is described. The said process comprises treating a mixture of 3- and 4-nitrophthalic acid, which mixture is free from inorganic acid residues, in an aqueous-organic medium containing 1-20 percent by volume of water, at a temperature of between 20 DEG  and 100 DEG  C., stepwise with a base capable of forming salts of 3- and 4-nitrophthalic acid, which salts are essentially insoluble in the reaction medium, the treatment being carried out by adding base until a pH value of about 2.8 is obtained, separating the precipitating product consisting mainly of a 3-nitrophthalic acid mono-salt, subsequently precipitating, by the addition of further base, a product consisting principally of a 4-nitrophthalic acid salt, and finally converting the resulting nitrophthalic acid salts separately into the corresponding free acids, and optionally purifying these. The 3- and 4-nitrophthalic acid can be obtained by the process according to the invention in a simple manner in an isomer-free form and in good to very good yields.

Title: Base isolation device
Inventor: HOSOKAWA YOJI
IPC: F16F15/02
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To make the device small-sized, hold base isolation function for a long term, and improve comfortability, by arranging journal bodies over two sorts to be combined in parallel, and making combination of the journal bodies into a plurality of steps to join together the displacement quantities of the respective steps of the journal bodies. SOLUTION: When earthquake force over a prescribed value is applied, lock of triggers 13 is released, and sliding journal bodies 11a, 11b, 11c and a rolling journal 12 are relatively moved in the horizontal direction. Accordingly, vibration due to earthquake force transmitted from a lower structure 3 to an upper structure 2 is lightened. Sliding journal by the slide journal bodies 11a, 11b, 11c and rolling journal 12 are combined together in parallel, and supporting force is enlarged by the sliding journal bodies 11a, 11b, 11c. The friction coefficient is made small by the rolling journal 12, and hence the shake of the upper structure 2 can be made small. Hereby, base isolation from a large-scaled building to a detached house is appropriately performed, and comfortability can be improved.

Title: Apparatus for measuring residual stress
Inventor: MURAYAMA RIICHI
IPC: G01N29/00
Filed: 1989-03-22
Abstract: PURPOSE:To accurately measure residual stress without receiving the effect of temp. by measuring the propagation time of the electromagnetic ultrasonic wave generated on the side of a magnet over the predetermined distance in the magnet and correcting the propagation time measured value of an ultrasonic wave through a material to be inspected on the basis of the measured result. CONSTITUTION:Electromagnetic ultrasonic waves polarized in two directions mutually crossing at a right angle with respect to an iron core 11 having predetermined reference temp. in the measurement of residual stress are generated on one end surface of the iron core 11 by probe coils 13a, 13b and reflected from the other end surface thereof and one reciprocating time of said ultrasonic waves between both surfaces is measured to calculate the reference propagation speed in the iron core 11. Then, the deviation with the reference value of a propagation speed is calculated from the propagation time of a material 2 to be inspected. Since the ratio of this deviation to the reference value is equal to the ratio of the deviation of the propagation speed measured in the material 2 to be inspected with the reference value to the reference value, the propagation time over the predetermined distance in the material to be inspected is corrected on the basis of said ratio. By this method, residual stress can be accurately measured without receiving the effect of temp.

Title: Communication controller
Inventor: TOBE YOSHIHARU
IPC: H04L13/00
Filed: 1983-04-22
Abstract: PURPOSE:To prevent erroneous communication by reporting a bus error to a central control part and resetting only a line control part if the bus error is detected during the direct memory access transfer between the line control part and a main storage part. CONSTITUTION:In case of reception of data from a line, receiving data is transferred from a line control part 3-i to a main storage part 2 through a bus 4 by direct memory access (DMA). At this time, a parity bit is generated by a bus error detecting circuit 8-2 and is added to receiving data and is transferred on the bus 4, and a parity error is detected by a bus error detecting circuit 8-1. When the error is detected by the circuit 8-1, a bus error signal 9 is outputted, and simultaneously, a line control part reset signal 11-i resultant from AND between this signal and a bus use right assigning signal 7-i is outputted, and only the control part 3-i is reset. A bus error reporting signal 10 is outputted to a central control part 1. Thus, since the line control part is reset before the end of transfer if the bus error is generated during DMA transfer, erroneous communication is prevented.

The thus finished bush 6 is press- fitted into the recess 11 of the housing 2. In this manner, after the bush 6 is secured to the housing 2, it is not necessary to mechanically machine it. In addition, since only the bush 6 is separately mechanically machined, the machining accuracy can be improved.

Title: Stationary induction apparatus
Inventor: KURODA YUTAKA
IPC: H01F27/32
Filed: 1984-04-10
Abstract: PURPOSE:To prevent a corona generation by reducing concentration of an electric field by decreasing effectively the volume of a solid insulator between windings and an iron core, with a method of forming a spacer, which insulates and supports the winding from the iron core, in a hollow shape. CONSTITUTION:Because the spacer 8 which supports each disc 1 through insulation channels 3 respectively is formed in a hollow shape, the number of the insulators with a high permittivity located between windings and the iron core 7 is reduced. The rate of materials other than a solid insulator e.g. liquid or gas, is increased. Consequently equipotential lines of an electric field in the area other than the solid insulator becomes coarse as compared with conventional ones and an electric field concentration is alleviated. Also, weight reduction of the apparatus is made possible by forming a spacer in a hollow shape.

Filed: 1978-06-13
Abstract: PURPOSE: To obtain high-frequency alternating current power by means of thyristors with normal turn-off time, by mounting a plurality of inverter units in parallel with load, and by successively change-over operating each unit every one period of alternating currents.
