IPC: C08L23/00
Filed: 1989-10-16
Abstract: PURPOSE:To produce the title spherical particles of a polyolefin resin with a particle diameter of 50mum or lower at a high yield by thermally dissolving the polyolefin resin in a specific mixed solvent in a nonoxidative atmosphere and then slowly cooling in a specified manner. CONSTITUTION:In a process wherein a polyolefin resin is thermally dissolved in a solvent in a nonoxidative atmosphere and then slowly cooled to precipitate fine particles of the polyolefin resin in the slow cooling step, the resin is dissolved at about 130 deg.C in a solvent comprising 80-50vol% xylene and 20-50vol% methylglycol and fine resin particles with a diameter of 50mum or lower are precipitated. The solubility of the resin and the precipitating properties of the fine particles vary with the type of resin. For a low density polyethylene, the mixed solvent comprising 70 pts. xylene and 30 pts. methylglycol is effective; for a polypropylene, 60 pts. xylene and 40 pts. methylglycol; and for a modified polyethylene, 50 pts. xylene and 50 pts. methylglycol.

Title: Gas turbine controller
Inventor: NAGATA KAZUE
IPC: F02C9/40
Filed: 1990-10-05
Abstract: PURPOSE:To improve the control stability at the time of a fuel changeover by controlling the fuel changeover through a fuel control command being outputted out of a load limiting control part being not affected by governor free control. CONSTITUTION:In a gas turbine controller which controls each changeover of both first and second fuel types, a load limiting control part 19 outputs a fuel valve opening command signal to a fuel selector circuit 10 via a low value selector circuit 16 upon receiving a signal out of a load control part 12. Then, a selector control part 20 is selected to either of a speed load control part 13 or the load limiting control part 19. Here, the load limiting control part 19 is formed into such a structure as not superposing a governor free signal attributable to system frequency as in the speed load control part 13. With this constitution, since fuel selector control is carried out by a fuel control command being outputted from the load limiting control part 19 being not affected by any governor free control, control stability at time of the fuel changeover is thus improvable.

IPC: G06K9/34
Filed: 1993-10-25
Abstract: PURPOSE:To attain the continuous input of characters by moving the display area of the handwritten image information or its recognition candidate information to a 2nd area after the recognition processing is started and then by clearing a 1st area. CONSTITUTION:This device is provided with a recognition frame (p) being a 1st area used for the input and display of a subject of recognition jointly, a following candidate display frame (o), a recognition candidate display frame (n) serving as a 2nd area exclusive for display, and a following recognition candidate display frame (m). The recognition processing is started for the handwritten image information supplied into the frame (p). Then the display of the handwritten image information or its recognition candidate information is moved to the frames (n) and (m), and the frame (p) is cleared. Therefore the handwritten input is possible to the frame (p) serving as a handwritten input area even before the input handwritten image information is recognized. Thus plural characters can continuously be inputted.

Title: Video mixer
Inventor: HASHI KENJI
IPC: H04N5/262
Filed: 1987-10-22
Abstract: PURPOSE:To reduce the number of the uses of a delay circuit and easily to process a control signal for controlling a phase by simultaneously switching a phase control pulse according to the phase difference of an input video signal with a video signal in the switching circuit of an input, receiving the phase control pulse in the phase adjusting circuit of a post step and obtaining a phase adjusted signal. CONSTITUTION:The phase coinciding input video signal is supplied to an input terminal 14, switched in switching devices 15, 17, and a video signal processing by mixing, key synthesizing, and a synthesis by wiping is executed in a mixing circuit 11 via the phase adjusting circuits 1, 2. A similar processing is executed in mixing circuits 12, 13. When the output of the mixing circuit 12 is defined to be the input of the mixing circuit 12, a cross point to a signal from the mixing circuit 12 is taken in the switching device 15 or 17. A synchronizing pulse switching device 16 or 18 selects and outputs a pulse having the phase corresponding to a delay time delayed by the output of the mixing circuit 12. Thereby, the phase adjusting circuit 1 or 2 controls the phase. Accordingly, even when the phases of all inputs are different, they can be corrected in the phase adjusting circuit.
