Abstract: PURPOSE:To simplify the handling, by mounting a transistor for one phase portion, a cooling body, a cooling fan and a smoothing capacitor onto a long- stripped frame body and by forming a phase unit with various kinds of terminals provided there. CONSTITUTION:A phase unit 101 long-stripped in the longitudinal direction up and down is formed with a pair of arms at its center where two transistors(Tr) 102 are connected in parallel to each arm. Six units of the phase unit 101 are arranged in right angles against the above longitudinal direction. A transistor inverter 100 is thus constituted. The phase unit 101 is equipped with a product of one phase portion composed of the Tr 102 of a pair of arms, a cooling body 104, a cooling fan 109, a smoothing capacitor 110, etc., and is mounted onto a long-stripped frame body 103 in the longitudinal direction.

Wiring patterns 7 run between those lands and a land P and a land Q are connected to each other without interlayer contact holes and jumper wires. As the sizes of the divided lands can be nearly the same as the sizes of lands 8 for the other small component 9, if a quantity of solder applied to one land is determined, proper quantities of solder for all the lands can be obtained. As uniform surface tensions can be applied to the surface mount component 5 by solder on the lands of four corners, it is accurately aligned to the correct direction.

Title: Continuous esterification of methacrylic acid
Inventor: MIYANOHARA ISAO
IPC: C07C69/54
Filed: 1979-02-07
Abstract: PURPOSE: To obtain methyl methacrylate continuously in high yields, by reacting methacrylic acid with methanol in the presence of a specific organic solvent using a distillation column.  
     CONSTITUTION: The distillation column 1 is charged with methacrylic acid and an acidic catalyst from the top of the column 1 (the lines 2 and 3) and with methanol from the bottom of the column (the line 4). A solvent (e.g., toluene) consisting of a hydrocarbon having a boiling point not lower than 100°C under a normal pressure is fed to the position (the line 5) higher than that of methanol supplied in the column. Methacrylic acid is reacted with methanol in the presence of the solvent to prepare a product, which is simultaneously separated by distillation to give methyl methacrylate continuously. The vapor-liquid equilibrium relationship between methanol and methyl methacrylate can be neglected by the use of the solvent, and the reaction and distillation can be carried out in any amount of methanol, a large or a small amount.

Title: Method and apparatus for decoding two-freqeuncy data signal
Inventor: KURARENSU HARISON
IPC: G11B20/14
Filed: 1991-01-09
Abstract: PURPOSE: To precisely and efficiently decode a deteriorated two frequency-signal. CONSTITUTION: A multiplexer 13 is provided and the sample of the two- frequency data signal is repeatedly obtained at the time of reading the data signal in a magnetic read head. The samples are converted into a series of digital values showing the values (amplitude and polarity) of the data signals. The two-frequency signal is sampled with the sufficiently high frequency so that the digital samples precisely show the two-frequency data signals. A knowledge digital filter processes the digital value and decodes the two-frequency data signal. When the two-frequency signal is sampled and is digitized, all the processings are executed on the digitized sample so that only one reading on a magnetic stripe is required for the processing.
