IPC: G06T15/00
Filed: 1984-09-28
Abstract: PURPOSE:To improve the processing efficiency for display of a curved surface and also to prevent the deviation of displayed pictures, by converting the 3- dimentional data to be displayed cubically into the 2-dimensional information and then converting the 2-dimensional information into the 3-dimensional data again after dividing an optional curved surface into basic polygons. CONSTITUTION:When the graphic processing (change of a cubic form, etc.) is carried out via a light pen 6 or a keyboard 5 of a display controller 4, a solid data handler 2 is started by a processing part 7. The handler 2 sends the solid model data SD taken out of a file 1 to a polygon dividing part 9 via a bus 8. The part 9 divides the data SD into surfaces and at first converts the 3-dimentional data into the 2-dimensional data via a 2-dimentional conversion part 10. In other words, the basic polygons obtained by dividing an optional curved surface are converted into the 2-dimensional parameter spaces without using the floating point arithmetic. These parameter spaces are converted again into the 3-dimensional data. Thus it is possible to improve the processing efficiency for display of a curved surface and also to prevent the deviation of displayed pictures.

Abstract: PURPOSE:To prevent the white omission of an image and the solidification or melt- fixing of a toner in a developing device by measuring the emission time of a laser beam in accordance with a picture signal and sending a prescribed signal when the contents of a storage means exceed a preliminarily set reference value. CONSTITUTION:A picture signal fv inputted to an image memory device is modulated by a modulator 1 and is amplified to a laser input voltage, and the emission power of a laser 2 is changed in accordance with the amplified signal. Meanwhile, a counter 3 integrates and counts the light emission time of the laser 2 from the output of the modulator 1, and the counter output is corrected in accordance with the laser light emission power by a correcting circuit 5 and is integrated and stored in a memory 6. A comparator 7 compares a value (x) stored in the memory 6 with the preliminarily set reference value; and if the value (x) is equal to or larger than the reference value (y), a signal is outputted to a controller 8, and a toner replenishing signal S indicating toner replenishment or cartridge replacement is sent to a display means. When the toner is replenished or a cartridge is replaced, the memory 6 is reset. Thus, white omission due to lack of the toner and the solidification or melt-fixing of the toner due to excess replenishment are prevented.

IPC: H03F1/42
Filed: 1982-11-19
Abstract: PURPOSE:To prevent an output transistor (TR) from breaking down in an accidental state by turning off the output TR through a detection TR which conducts when an output terminal becomes a specific voltage higher than a power source. CONSTITUTION:The emitter voltage of the detection TR12 never rises above a power source terminal Voltage VCC in a normal state, so a protecting circuit 11 is not in operation and no influence is exerted upon an SEPP amplifier. If the power source short-circuits to a load terminal 18, the voltage corresponding to the sum of the power source voltage VCC that a power source capacitor 15 holds and the charging voltage VCC/2 of an output coupling capacitor 17 is developed at an output terminal 16 and applied between the collector and emitter of the output TR6. The detection TR12, on the other hand, turns on when applied at its emitter terminal with the sum of the power source voltage VCC and forward voltages VF9 and VF10 of diodes 9 and 10 to turn on the breaking TR7 of a breaking circuit while turning off the output TR6, preventing its break-down.

Filed: 1983-10-28
Abstract: PURPOSE:To make it possible to reduce a min. measurable particle size without using a lens in a light condensing system, by crossing a specimen stream and laser beam at right angles at the focus of a first parabolic surface mirror and condensing laser beam to a photoelectric converter provided at the focus position of a second parabolic surface mirror. CONSTITUTION:Specimen gas containing an aerosol passes the inside 17 of a short double pipe and passed the focus of a first rotary parabolic surface mirror 11 as a minute diameter gas stream. Laser beam passes a passage 15 and crosses the specimen stream at right angles at the focus 13 and beams scattered by fine particles are reflected by the parabolic surface mirror 11 and enter a second parabolic surface mirror 21 as parallel beams. The beams reflected by the parabolic surface mirror 21 are condensed to the photodiode 23 at the focus position and converted to a photoelectric signal and the particle size distribution of the aerosol is measured. Therefore, there is no noise based on the scattering on the surface of a lens because no lens is used and a min. measurable particle size becomes small.

Title: Ignition timing control device of engine
Inventor: TAKEDA YUJI
IPC: F02P5/153
Filed: 1989-08-04
Abstract: PURPOSE:To suppress knockings frequently generated in one cylinder successively by allowing a correcting means to make incremental correction for the angle delay of the ignition timing if a successive knocking judging means judges that knockings have occurred in a single cylinder. CONSTITUTION:When a by-cylinder knocking judging means MB judges that knocking has occurred in any cylinder of a multi-cylindrical engine MA, a knocking control means MC makes angle delay for the ignition timing of all cylinders. When the judging means MB has judged that knocking has occurred in a certain cylinder, and if a successive knocking judging means MD judges that the applicable cylinder is identical to the one in which the previous knocking occurred, an at-successive-knocking correcting means ME of the abovementioned knocking control means MC makes incremental correction for the angle delay of the ignition timing to be angle delayed at each occurrence of knocking. Thus the response in knocking control is enhanced.
