Inventor: SAKURAI MASAO
IPC: C10G9/00
Filed: 1981-06-18
Abstract: PURPOSE: To obtain a cracked gas, etc. from the top of a reaction column and pitch from its bottom using the small-sized reaction column without causing troubles, by dividing the upright cylindrical type reaction column into the top and bottom parts by partition plates with open hole parts, feeding a heated petroleum heavy oil to the top reaction zone, cracking it.  
     CONSTITUTION: A petroleum heavy oil from the line 1 is heated at 400W510°C by the heating furnace 2, fed to the top reaction zone 5 of the reaction column 4 with the stirring machine 8, and the greater part of cracking is finished. A large amount of evolved gases and oil vapor are exhausted from the line 9 to the outside of the system. The reaction solution is sent from the open hole part of the partition plate 7 to the bottom reaction zone, passed through each open hole part of the partition plates 7', 7", and 7''', and made to flow from the top to the bottom as a piston flow, to form β resin substance, quinoline-insoluble substance (pitch component), etc. The cracked gas in the bottom reaction zone is raised in the form of bubbles and exhausted from the line 9. While the pitch is taken out from the line 10 to the outside of the system.

Filed: 1979-07-26
Abstract: PURPOSE:To reduce used resin amount of the molded trnsformer and to improve crack resistance thereof by dividing the primary coil into main and tapped coils, separately molding the coils, and associating the coils to form the primary coil. CONSTITUTION:The primary coil 10 is divided into main coil 11 and tapped coil 15, and the coils 11, 15 are separately molded. The thickness t1 of the molded layer of the end 14 of the main coil 11 occupying most of the primary coil is formed thinner than the thickness t2 of the molded layer of the end 18 of the tapped coil 15 so as to substantially equalize the thicknesses of the respective molded layers of the main coil 11. In this manner the used molded resin is largely reduced to equialize the temperature rise and distribution of the main coil so as to reduce the thermal stresses of the molded layers upon energization thereof in order to improve the crack resistance thereof.

Title: Reset signal generating circuit of microprocessor
Inventor: TOTSUKA YUKIMASA
IPC: H02J1/00
Filed: 1984-05-11
Abstract: PURPOSE:To completely give writing pulse to a no-break memory, by inhibiting the supply of reset signals to a CPU which is performed independence on a power failure detecting signal during the effective period of a write signal. CONSTITUTION:When a power failure occurs, a voltage VCC starts to make a rapid drop and, when the voltage VCC coincides with Zener voltage, a power failure detecting signal VM is generated from a comparator 11. Then a transistor (Tr) 7 is turned off and the power supply to a RAM4 is switched to a battery 9. Moreover, when a write (-WR) signal from a CPU1, whose signal generating period is 450nS, is turned off after the power supply is switched to the back- up power source, the output of a gate 6 becomes high in level and a signal is impressed upon the reset terminal of the CPU1. In this case, writing in the RAM4 can be terminated within the operable time (100mS) of the CPU1, because the generating time of the -WR signal is about 450nS.

Abstract: PURPOSE:To wrap various different sized articles to be packaged by a method wherein the title device is constituted in such a manner that at the internal center of an annular shaped article to be packaged which is turning on a horizontal surface, a film roll can pass through to circulate. CONSTITUTION:When a rotating body 5 is driven by a plurality of driving gears 10 which synchronously rotate, a film roll 20 passes through the inside 4 of an article to be packaged 3 while sending out a film F and winds the film F around the peripheral surface of the article to be packaged. Then, about when the roll 20 reaches a position B from a position A, the front tip of the film is released and joins to the peripheral surface of the article to be packaged by the self-tackiness of the film F. Then, the roll 20 continuously keeps rotating on the circumference of the rotating body, and the article to be packaged rotates on a horizontal surface with a fixed rotational ratio with the rotation of the roll 20, and thus the film F is wound around the surface of the annular shaped article in a spiral state. By this method, the film F is favorably wound on the whole surface of the article to be packaged.
