Title: Treatment of cut tar
Inventor: YAO TADASHI
IPC: C10G47/00
Filed: 1983-10-12
Abstract: PURPOSE:To attempt to utilize cut tar along with obtaining an absorbing oil alternative as crude benzene absorber, by hydrogenating decomposition of cut tar produced by removing fraction of specific boiling point or lower after distillation of coal tar, followed by distillation to collect fraction of specific boiling point range. CONSTITUTION:High- or low-temperature tar produced along with dry distillation of coal is distilled to remove a fraction of a boiling point <=270 deg.C to obtain cut tar. This tar is subjected, generally in the presence of iron-based catalyst such as red mud and co-catalyst such as sulfur compound each in an amount of 1-10wt%, to hydrogenation decomposition pref, at 400-500 deg.C under a hydrogen pressure 100-200kg/cm<2>G followed by collecting fraction of a boiling point 200-300 deg.C and, if required, also separating a second fraction of a boiling point 300-350 deg.C to effect recovery. The former fraction is mixed, if necessary, with part or all of the latter one to put to application as an absorbing oil alternative.

IPC: E04F15/02
Filed: 1992-06-25
Abstract: PURPOSE:To make a floor covering body accurately and easily stickable to both floor and wall surfaces even if both external and internal angles of these surfaces are geometrical forms as well as being done by unskilled labor by using an accessary pattern provided with a bending notch in a specified position. CONSTITUTION:An accessary pattern (a) is placed on a floor surface of an external angle (a'), and an I point of this pattern (a) is pressed to a wall surface so as to make it so as to somewhat rise up along the wall surface from the floor surface. At this time, since a bending notch is installed behind two line segments GI, IF of the pattern (a), two triangular parts GID and IDF rise up along the wall surface. At this point of time, an apex B is applied to a reference line. Next, a floor covering body is placed on the pattern (a) and both of them are bonded together. In succession, a part of the external angle (a') is partially turned up, cutting the floor covering body equivalent to an extension part of a line segment ID part of the pattern (a) and two line sects DC and DA. Then the pattern (a) is separated, and the floor covering body is stuck fast to the floor surface and the wall surface. In addition, an insufficient triangular part is replenished with a fragment of the floor covering body.

IPC: C23C2/12
Filed: 1991-07-04
Abstract: PURPOSE:To simultaneously form a zinc phosphate film of a required deposition on the surfaces of an aluminum-iron joined body by adjusting potential patterns. CONSTITUTION:A treating stage for maintaining the aluminum-iron joined body at the potential at which hopeite Zn3(PO4)2 is formed on the surface of an aluminum material and a treating stage for maintaining the aluminum-iron joined body at the potential at which phorphophllite Zn2Fe(PO4)2 is formed are alternately repeated. At least one of these treating stages are executed by a force electrolysis. The fluctuation patterns of the potential include various patterns, such as forced electrolysis-forced electrolysis, non-electrolysis-forced electrolysis, and forced electrolysis-non-electrolysis, as shown in Fig. The hopeite film is formed on the surface of the aluminum material and the phorphophyllite film is formed on the surface of the iron material in this way. The execution of the surface treatment for coating of the aluminum material is thus possible without adversely affecting the surface treatability, corrosion resistance, etc., of the iron material.

Title: Radio-controlled self-traveling mowing machine
Inventor: FURUKI KUNIO
IPC: G05D1/02
Filed: 1986-08-14
Abstract: PURPOSE:To surely detect abnormality and to reduce the cost of a self-traveling mowing machine by using plural pulse signals of different widths and cycles as command signals and deciding the abnormality in case an abnormal state of the detected value of said widths or cycles lasts longer than a prescribed period of time. CONSTITUTION:A control part 11 detects first each pulse width of all command signals and this pulse width is set at W1-W2 in terms of the count value of a counter 27. Then the pulse cycle is detected when all count values are normal. In this case, the cycle is set at T and the pulse interval is detected in place of the cycle. In other words, one of those signals received from a receiver 25 is converted by an inverter 35 and supplied to the counter 27. Then a normal state is decided when the pulse width is set at T-W1-T-W2 in terms of the count value. Thus an abnormality reception flag is turned off. While the counter 27 is set at 0 if an abnormal state lasts for a period of a set time (t). Then said reception flag is turned on and a warning lamp 43 is blinked in an abnormality output routine. Then a mowing machine itself is stopped at that position with brakes applied.

Filed: 1986-08-14
Abstract: PURPOSE:To take out a constant quantity with high accuracy by adjusting weight by means of a shatter which partially closes a falling passage from a conveying conveyor when the weight of a measuring bucket becomes a defined weight. CONSTITUTION:The weight of a measuring bucket 3 is measured by a load cell. Articles which are continuously fed by a conveying conveyor are fed to the measuring bucket 3 via a hopper 2 and, when they reached a constant quantity, the bottom of the bucket 3 is opened and the articles are received by a hopper 14. Shatters 15, 16 are provided while being slightly shifted in the vertical direction from each other in between the hopper 2 and the measuring bucket 3. When the articles of a predetermined weight less than the final weight to be measured by the measuring bucket 3 fall into the measuring bucket 3, the shatter 15 is projected out to a falling passage by means of an air cylinder 17, to partially close the passage. And, the articles are allowed to fall down into the measuring bucket 3 bit by bit through the narrowed passage and, as they reached the final weight, the shatter 16 is projected out completely closing the falling passage. Accordingly, the measurement of a constant quantity can be carried out with high accuracy.
