Title: Phase locked loop and camera device
Inventor: NAKAJIMA TAKAYUKI
IPC: H04N5/12
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To output a synchronizing signal which is synchronized with an external reference signal even when a phase is continuously varied. SOLUTION: A phase synchronization circuit is provided with a setting timing signal generating block 5-4 for generating setting timing signals A and B in different counting values Dv which are counted in a counter block 5-1 and with a setting timing control block 5-5 for changing a setting timing control counter value into a pulse generation counter value which is inputted from an external part by one of the timings of the setting timing signals A or B. When the pulse generation counter value coincides with the setting timing signal A, the setting timing signal B is selected so that the pulse generation counter value is prevented from coinciding with a timing value which is for changing the setting timing control counter value into the pulse generation counter value. Then, the phase is continuously and variably adjusted while keeping the lock state of a phase locked loop.

IPC: B29C45/40
Filed: 1980-11-20
Abstract: PURPOSE:To close an air release port quickly and surely when melt to be injected arrives at a valve body by maintaining a valve in a closed state by means of a member dentaining the valve in an open state with a device of closing a gas discharging passage opening at the side face of the valve through sliding of the valve in its axial line direction. CONSTITUTION:When stationary and movable dies 11, 12 are mated and a spool 31 is lowered with a cylinder 52 by curving a leaf spring 38 downward, a valve 41 closes a vent groove 22, and opens a gas discharging bypass valve 25. At this time, the spring 38 assumes a corrugated shape and its central part is in a liftable state with relatively small lifting force. Thereupon, when molten metal is cast into a cavity 15, the gas therein flows through the groove 22, a passage 25, a valve chamber 47 and a discharge port 36. When the melt ascends in the groove 22, the valve 41 is kicked up by the impact thereof, by which the spring 38 is curved upward. Thereby, the valve 41 is positioned upward, and closes the passage 25. In spite of discontinuous striking of the melt against the valve body owing to mixing with the gas, the valve 41 is maintained upward by the spring 38.

Abstract: PROBLEM TO BE SOLVED: To improve a print processing speed by shortening an under color removal processing time. SOLUTION: An interface section 11 receives print data to which color numeral information is attached in the unit of bands. This color numeral is the number of pixels that results from subtracting the number of white pixels from the total number of pixels in a band. An edit section 12 analyzes and stores received data. An image drawing section 14 compares the color numeral in the unit of bands with a predetermined threshold value. In the case that the color numeral is higher than a threshold value, an under color removal UCR processing section A16 applies the under color removal processing to all the print data. When not, a UCR processing section B17 applies the under color removal processing to the print data from which the white pixels are eliminated. A video output control section 19 reads a video signal from the print data to which the under color removal processing is applied.  An engine control section 20 allows a printer engine 21 to print to the video signal.
