Title: Production of pitch
Inventor: MAEDA TOYOHIRO
IPC: B01F29/84
Filed: 1986-12-19
Abstract: PURPOSE:To obtain pitch particularly suitable for the production of carbonaceous materials, by thermal polymerization, in a vacuum system, of a primary QI component-removed heavy oil or pitch while separating and eliminating the low-boiling point components to prevent the spun fibers at high temperatures from fusing. CONSTITUTION:A heavy oil or pitch from which the primary QI component has been eliminated by means of e.g., filtration is brought to thermal polymerization at 100-400 deg.C in a vacuum system (pref. under <=100Torr) while separating the low-boiling point components on blowing a gas containing oxygen and/or ozone, thus obtaining the objective pitch. The amount of said gas to be used is, in general, such as to be, on an oxygen or ozone basis, ca. 0.1-2(pref., ca. 0.2-0.8)l/min per kg of the heavy oil or pitch.

Title: One piece type air conditioner
Inventor: IKEDA KAZUO
IPC: F24F1/02
Filed: 1990-11-13
Abstract: PURPOSE:To reduce the noise by mounting a scroll compressor as a compressor for one piece type air conditioner. CONSTITUTION:A scroll compressor 19 is mounted on this air conditioner wherein the noise is small, say, 1000Hz and below while operation vibration is about 10% or lower than that of a rotary compressor. Since the scroll compressor is installed as a compressor, a compressor noise of less than 1000Hz, which is difficult to insulate in nature, is reduced. Furthermore, the operation vibration is reduced as well, thereby eliminating any possibility to make resonance with a wall or window having characteristic frequency of 500Hz and lower. It is, therefore, possible to supply a low noise and one piece type air conditioner.

Title: Catalyst combustion device
Inventor: SAKANE YASUAKI
IPC: F24C1/08
Filed: 1989-11-21
Abstract: PURPOSE:To prevent any trouble due to abnormal operation of a catalyst layer by detecting the existence of harmful combustible gas by detecting a change in detected temperature by an auxiliary catalyst layer temperature detector element or a deviation between the detected temperature and an initial set value. CONSTITUTION:Whilst a catalyst combustion device is operated and a combustion catalyst layer 1 is preheated for transition to a stationary combustion state, an auxiliary catalyst layer 2 is also heated by high temperature waste gas discharged from the combustion catalyst layer 1 and is stabilized after reaching a catalyst activation temperature of about 210 deg.C or higher. Once abnormality is produced on the catalyst combustion device, harmful combustible gas is discharged which gas is mainly oxidized and combusted at an inlet of the auxiliary catalyst layer 2 to raise temperature. The abnormality is decided when said temperature changes to a higher temperature by 10 to 20 deg.C than stable temperature detected at the inlet side of the auxiliary catalyst layer 2, and fuel is interrupted but operation of a fan 16 is continued for extinguishment and cooling. Hereby, an abnormality lamp is lighted. Also when the combustion catalyst layer 1 is deteriorated, the abnormality is decided when the harmful gas is discharged and the inlet temperature of the auxiliary catalyst layer 2 is detected to be higher about 20 deg.C than a normal one.

Title: Method for expressing and printing continuous gradation pattern
Inventor: KANEMOTO YUJI
IPC: B41F17/14
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To eliminate a color drift a color tone change, a color omission or the like by separately selecting a pattern from gradation original data in an arbitrary density area, and representing the density according to halftone dots disposed according to a screening method. SOLUTION: Image data input to a computer is compressed to convert an original density into a printing density, and gradation corrected. The gradation corrected image data is laid out to decide its image size. Here, a density chart is formed so that a first image processing data is an 'entirety'. A density area 100 to 30% is selected from the first image processing data to a 'design'. Further, the first data is set to a 'dark brown' and a 'brown' by selecting density areas of 100 to 80% and 80 to 50%. Further, the previous 'entirety' is set by selecting a density area of 50 to 0%, and set to a 'light brown'. Halftone dots are disposed on five image data such as the 'designs' corrected to raise its contrast according to an FM screening type, and engraved.

Title: Image processor
Inventor: HARA HIROYUKI
IPC: G06T3/00
Filed: 1990-11-09
Abstract: PURPOSE:To exactly segment only a necessary segmenting area by designating the area to be segmented in accordance with an inclination even if image data to be segmented is inclined. CONSTITUTION:With respect to display image data, two points are designated by a pointing device 7. In this regard, this designation of two points is executed in order to calculate an inclination of image data, and an angle derived by a straight line for connecting two points and a horizontal axis is an inclination of an image, therefore, although a first point is arbitrary, as for a second point, it is necessary to designate it in a position in which an inclination of the image can be calculated. By designating two points, an inclination alpha is derived, and by designating a start point and an end point of an area segmented by using the pointing device 7, a rectangular frame having the inclination of alpha in which the start point and the end point are origins is displayed on a display device 3. In such a state, when an operator designates a segment processing, the image data in the rectangular frame becomes an object of the segment processing. In such a way, only a necessary segment area can be segmented.

CONSTITUTION:The storage circuit 12 storing the detection signal of the phase comparator 2 is inserted between the phase comparator 2 and the tri-state output buffer circuit 15. Even when the operating speed of the tri-state output buffer circuit 15 upon the receipt of an enable signal till reaching the enable state is slower than the operating speed of an enable signal generating circuit 3, the storage circuit 12 stores the detection signal of the phase comparator 2 and gives an output to the tri-state output buffer circuit 15. Thus, the loss of the detection signal of the phase comparator 2 while the tri-state output buffer circuit 15 is in the enable state is prevented and no malfunction is caused.

Title: Method for reducing oscillation mark on continuously cast slab and continuous casting mold therefor
Inventor: TAKADA SHIGENOBU
IPC: B22D11/16
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce the depth of an oscillation mark by making the tapered degree on the inner surface of a mold in the prescribed ranges at respectively the upper part and the lower part from a reference position, using a meniscus level in the mold as the reference. SOLUTION: The tapered angle θ1 of the inner surface of the mold at the part upper than the meniscus part is taken larger than that, θ2 of the lower part and the mold is formed in an upward-widen shape. Concretely, the value θ1 of the tapered degree of the mold is made 1.5-3.0%/m and the value θ2 is made 0.7-<1.5%/m. Since the solidified shell 2 developed at the large tapered part θ1 is extended at the time of passing through the small tapered part θ2 , if the rhomboidal deformation of the initial stage solidified shell at the meniscus part and the oscillation mark caused by the collision between slag rim and the solidified shell at the time of flowing-in of the powder, are developed, these are extended to the lower part of the mold and can be smoothened.  Further, the rhomboidal deformation of the solidified shell is caused to reduce and the oscillation mark is reduced by these synergetic effects.
