Title: Production of polyether-polyol
Inventor: TSUBAKIMOTO TSUNEO
IPC: C08G65/26
Filed: 1983-07-29
Abstract: PURPOSE:To produce a polyether-polyol in good efficiency while facilitating the solvent removal after the reaction, by reacting a polyamino-1,3,5-triazine with an oxirane compound in the presence of acetonitrile. CONSTITUTION:A polyamino-1,3,5-triazine, e.g., (substituted) melamine, or (substituted) guanamine, is reacted with an oxirane compound (e.g., ethylene oxide or phenyl glycidyl ether) at about 60-180 deg.C and a molar ratio of about 1:1-1:200 in the presence of acetophenone in an amount of about 1-20 times, by weight, that of the above triazine by using a catalyst such as sodium hydroxide. Aceto- phenone which is used as the reaction solvent in the above reaction has a b.p. of 82 deg.C, so that it can be very easily removed and recovered after the reaction.

Title: Manufacture of metal powder
Inventor: IMAHASHI KUNIHIKO
IPC: B22F9/08
Filed: 1982-08-07
Abstract: PURPOSE:To solidify molten metal in the vicinity of an outflow opening for inhibiting the inclusion of molten slag in metal powder, in a spray method for manufacturing metal powder, by charging a cooling medium in the molten metal inside a tundish. CONSTITUTION:In spraying a fluid to molten metal flowing downwards to manufacture metal powder, a cooling medium such as a plurality of iron balls 12 is charged from a shooter 11 in a tundish 1 and sunk therein, just before the step of pouring molten metal into the tundish 1 is completed. Hence, the molten metal in the vicinity of a nozzle for molten metal is rapidly cooled and solidified, so as to inhibit the flowing-down of slag floating on the molten metal 8. Thus, the flowing-down of the slag-contg. molten metal can be inhibited, and the metal powder containing a small quantity of inclusions is obtained.

IPC: B23B29/034
Filed: 1988-06-06
Abstract: PURPOSE: To automatically realize a boring process and a precision cut process at the time of tool withdrawal by setting spring force so that the torque applied to an eccentric tool is made sufficiently larger than the counter torque at the time of a finishing cut and sharply smaller than the counter torque at the time of boring. CONSTITUTION: During peripheral cutting, particularly boring, in a workpiece, the spring force of a coil spring 7 is set so that the torque applied to an eccentric tool 4 is made sufficiently larger than the counter torque generated at the time of a finishing cut and sharply smaller than the counter torque caused by the large cutting force generated at the time of boring. A boring tool blade 3 is self-adjusted by utilizing the cutting force different during a roughing cut and during a finishing cut and the torque caused by it, thereby a boring process and a precision cut process at the time of tool withdrawal can be automatically realized.

Filed: 1990-05-30
Abstract: PURPOSE:To avoid a received picture from being directly observed by using a video camera, a video monitor, a microphone and a speaker as basic components and processing the received picture data and displaying the result onto the video monitor. CONSTITUTION:The received picture data is converted into a data at a spatial frequency region by a 2-dimension FFT (high speed Fourier transformation section) 4 in a digital filter section 8 and outputted to a filtering section 5. On the other hand, a filter control section 9 extracts a filter function stored in advance in a filter data memory 10 and outputs it to the filtering section 5 and the data of the spatial frequency region and the filter function are used to apply calculation and the high frequency component is eliminated from the data at the spatial frequency region and the result is restored into a picture data by the 2-dimension inverse FFT 6. When a picture by which a called party feels a sense of displeasure in this way, the filter function stored in the filter data memory 10 is used to eliminate the high frequency component of the picture data, then the received picture is fogged.

Title: Automatic window display correction device and method therefor in multiwindow system
Inventor: SHINDO NAOKI
IPC: G06F3/048
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the visibility of display contents of a window under another overlapping window by moving the coordinates of a window area in order to recognize only a specified area of a designated window. SOLUTION: An object window whose coordinates of a display correction area is previously registered at a display correction area management part 1 is moved or enlarged. When the object window is partly excluded out of a display effective range, a display correction judgement processing part 12 judges whether a registered area is included in the relevant area. A display correction area retrieval processing part 13 compares the position coordinates of the registered display correction area with that of a window non-display area which is taken out of a window non-display area management part 2 to detect a window non-display area that can include the display correction area. A display position correction processing part 14 moves an entire coordinate position of a window to include the display correction area in the detected window non-display area. Then, a correction drawing processing part 15 draws again and entire screen so as to place the window having the corrected position coordinates on the lowest surface.

IPC: B60W10/18
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To stop an engine automatically when the driver actuates a foot brake without giving any uncomfortable feeling to the driver. SOLUTION: For an automatic engine stop when predetermined stop conditions are satisfied, the lapse of a preset wait time Twait after S370 determines that the stop conditions are satisfied triggers an automatic engine stop, which wait time Twait is set depending on the foot-brake stamping torce in S360. A lighter pedal depression lengthens Twait to retard the automatic stop accordingly, while a stronger pedal depression shortens Twait to advance it to an automatic stop accordingly.

IPC: G01D5/18
Filed: 1983-07-30
Abstract: PURPOSE:To improve detecting accuracy, by electrostatically shielding both magnetoresistance circuits of series circuits having a pair or more of magnetoresistance bodies to each other. CONSTITUTION:A permanent magnet 4 forms a parallel magnetic field H. A plate shaped magnetic body 3 comprising a ferromagnetic body is formed so that the height is several mm., the width is several mm., and the thickness if about 0.5mm.. A magnetoresistance body 1 comprising InSb has the thickness of about 5mum, the width of 0.3mm., the length of 1mm., and the height of about 1.5mm.. Conductor paths 5 are formed by a copper film, and electrostatic shielding bodies 10 and 11 are formed by phosphorus bronze.

Title: Image processor, image reader and image processing method
Inventor: MATSUKUMA TAKASHI
IPC: H04N1/40
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To convert an image component accurately into a digital signal regardlessly of the magnitude of DC components by allowing the processing unit to have a means that detects the DC component included in an image signal and an elimination means that eliminates the DC component from the image signal. SOLUTION: A central control circuit 14 controls a D/A converter 16 to allow the D/A converter 16 to convert a digital reference signal Dref into an R color reference signal Rref. The D/A converter 16 provides an output of the R color reference signal Rref to an operational amplifier 4. Upon the receipt of the R color reference signal Rref, the operational amplifier 4 subtracts the R color reference signal Rref from an image signal Vb1 to generate an image signal Vc. The operational amplifier 4 outputs the image signal Vc to an Rin terminal of a multiplexer circuit 11. Since the R color reference signal Rref that is equivalent to a DC component of the image signal Vc is subtracted from the image signal Vc, no DC component remains in the image signal Vc. Thus, the image signal with high image quality is obtained independently of the magnitude of the DC component.
