As a result, a high molecular component in the petroleum type heavy oils is allowed to adhere to quinoline insol. particles in the coal type heavy oil and aggregated to increase the particle size, thereby easily removing the quinoline insol. component. Thus, effective application of coal type heavy oil and petroleum type heavy oil to starting materials for carbon material manufacture is enabled cheaply. Formerly, the former oil was considered to be difficult in use as the starting material, and the latter oil was selected from restricted kinds.

Title: Detecting method for point of accident in power cable system
Inventor: NUMAJIRI FUMIYA
IPC: G01R31/08
Filed: 1981-02-12
Abstract: PURPOSE:To locate a point of accident based on the amplitude of a current flowing  through detection lines connected to a contact point, by making the contact point  closed by a voltage caused in the secondary winding of a saturable reactor connected  between two terminals of an insulation joint box at a time when a dielectric breakdown accident takes place. CONSTITUTION:Supposing that a grounding accident occurs at a point X in a section  of the insulation joint box 3B1 in a phase B, a grounding current flows from a sheath  to the earth through the saturable reactor 4B1 and a joint box 2B, while flowing also  to the side of power source through a sheath in the phase B. Since the grounding current is always larger by far than a sheath current at the time of operation, a voltage  caused in the secondary winding 5B1 increases sharply and thereby the contact point  6B1 is closed by means of a bimetal and the like. Accordingly, with a prescribed DC voltage impressed on the detection lines 7a and 7b, a current flows corresponding to  the resistance values of the detection lines, which are proportional to a distance from  a prescribed position to the insulation joint box 3B1. The occurence of the dielectric  breakdown accident within the section of the insulation joint box 3B1 can be known  with ease from the value of the current and thereby a time required for restoration  can be shortened.

Title: Amplifying circuit
Inventor: FUKUDA YASUO
IPC: H03G3/10
Filed: 1987-01-29
Abstract: PURPOSE:To adjust the gain independently of the potential of an input signal by providing a switching means which activates either of first and second amplifying circuits which have different amplification gains for the input of the same input signal. CONSTITUTION:The first differential amplifier 1 has a high gain and the second differential amplifier 2 has a low gain. When a timing pulse is inputted on from the base of a transistor TR 5, TRs 4 and 5 are turned on or off in accordance with the high or low level of the timing pulse because a constant voltage VTH is applied to the base of the TR 4. Consequently, if the third differential amplifier 3 is used as a switching circuit to control turning-on/off of TRs 4 and 5, the first differential amplifier 1 is turned on or off in accordance with turning-on or off of the TR 4 and the second amplifier 2 is turned on or off in accordance with turning-on or off of the TR 5. Thus, an amplifying circuit is obtained whose gain is controlled independently of the potential of the input signal.
