Title: Image forming device
Inventor: YAMADA HIROYUKI
IPC: B41J2/52
Filed: 1995-05-25
Abstract: PURPOSE: To ensure the gradation by a multi-value output by allowing a parallel serial conversion section to output serially a multi-gradation bit map table synchronously with a plural-multiple clock signal so as to form an image of multi-gradation. CONSTITUTION: A main scanning direction counter 52 receives a dot clock VCLK from a plural multiple clock generator 51 and counts it to provide a binary count output to a lookup table 50. A subscanning direction counter 53 counts a signal HSYNC and provides a binary count output to the table 50. The table 50 decides a picture element data output pattern comprising white or black binary values as to a 16-gradation position and 4-bit output image data D0-D3 to be generated are written in a video buffer 45. The image data written in the buffer 45 are converted into a serial VDO signal synchronously with a 4-multiple clock outputted from the generator 51 in an S/P conversion circuit 46 to a laser driver, from which a 16-gradation output is attained.

IPC: F23D11/08
Filed: 1980-10-25
Abstract: PURPOSE: To prevent exactly damage to a vaporizing cylinder by combustion, the occurrence of back-fire combustion to a gas chamber, and the generation of noise of combustion for keeping the vaporizing combustion of mixed gas under good condition for a long period of time by using a system in which the direct injection and combustion of the mixed gas from a dilution chamber for the mixed gas is avoided.  
     CONSTITUTION: By a mixed gas dilution chamber 18 formed between a gas chamber 4 and the terminal open side of a vaporizing cylinder 8, part of a mixed gas to be injected and burned toward a combustion cylinder 1 is positively diluted, during contination of vaporizing combustion, by air supplied from an air supply chamber 2, mixed in flame inside the combustion cylinder 1, and burned without being directly burned on the discharge side of the dilution chamber 18. Thus, the continution of vaporizing combustion under good condition can be always kept by exactly turning the vaporizing cylinder 8, and also the generation of noise of combustion and the occurrence of back-fire combustion toward the gas chamber 4 can be exactly prevented.

Abstract: PURPOSE:To manufacture an excellent water resistant resin sealed semiconductor device capable of almost avoiding the current leakage by a method wherein, after separating respective semiconductor chips from an adhesive tape, but before resin sealing the ships, the surfaces of the semiconductor chips are selectively processed to prevent conduction. CONSTITUTION:A diode chip individually divided and separated from a semiconductor wafer 7 on an adhesive tape 9 is cleaned up to release the bonding agent layer of the adhesive tape 9 stuck on the surface but the carbon material 91 in an organic solvent is bonded onto said surface. Therefore, the diode chip 1 is picked up out of the organic solvent to be immersed in a water solution containing hydrogen fluoride.

Title: Magnetic drive system
Inventor: HATSUTORI KINYA
IPC: G06K15/06
Filed: 1978-12-08
Abstract: PURPOSE:To reduce the number of parts and power consumption by connecting one current detecting resistance to a plurality of magnets in common and controlling the input applied on the comparator in response to the number of the simultaneously driven magnets. CONSTITUTION:When driving pulses are applied on two input terminals A1 and A2, for example, these two driving pulses are added by a circuit 1 and thus obtained output voltage is applied on one input terminal of a comparator 3. At this time, there is no current passing through magnets M1-Mn, so the comparator 3 outputs logic ''1'' and outputs of NAND circuits G1 and G2 turn to logic ''0''. As a result, transistors T1 and T2 become ON and the magnet M1 and M2 driven. Total current IM passing through these driven magnets is applied on the other input terminal of the comparator. Both inputs on the comparator are compared to each other and the gates are controlled by the output obtained from the above comparison.
