Title: X-ray mask
Inventor: HORIUCHI TOSHIYUKI
IPC: G03F1/22
Filed: 1990-01-23
Abstract: PURPOSE:To improve the X-ray transmittance of an X-ray transmitting part to a large extent and to obtain an X-ray mask by which the X rays having the longer wavelength than a conventional device can be used for exposure by removing a supporting film at parts where the absorbing body of the X-ray mask are not mounted, and forming holes in the supporting film. CONSTITUTION:A supporting film 6 is applied on a hole part 5a of a mask substrate 5. Patterns 7 formed of an X-ray absorbing body are mounted on the supporting film 6. In this X-ray mask, the supporting film 6 at parts where the patterns 7 formed of the X-ray absorbing body are not mounted is removed. Thus, holes 8 are formed in the supporting film 6. For example, silicon nitride films are deposited on both surfaces of the mask substrate 5 made of silicon. Thereafter, a tantalum film is formed on the surface, and an SiO2 film is further formed thereon. Then, the SiO2 film selectively undergoes dry etching based on a resist pattern on which electron beam lithography is performed. Then, with the obtained SiO2 pattern as a masking material, a tantalum patterns are formed as the absorbing body patterns 7. Thereafter, the silicon nitride of the supporting film 6 undergoes dry etching with the tantalum patterns 7 as a masking material.

Inventor: HARA KENJI
IPC: G06F11/00
Filed: 1993-01-27
Abstract: PURPOSE:To write a program in a flash memory without always mounting any ROM different from the flash memory to a computer system. CONSTITUTION:This method uses the computer system provided with plural resistors R19-R0 for pull-down or pull-up for preparing one word of a jump instruction for each data line of a data bus 7 when each data line of the data bus 7 is in a floating state and a flash memory 2 to which the address of the jump destination designated by the jump instruction fixed by the resistors R19-R0 is allocated. When the system program has not been written yet, a freely attachable and detachable ROM, to which the restart address of a CPU 1 is allocated, is mounted on the computer system, when the boot program of the ROM is executed, the system program is written in the flash memory 2 corresponding to any computer different from the computer system, and the ROM is detached later.

Title: Automatic paper feeder for ziazo copier
Inventor: NAGATA SHIYOUICHI
IPC: B65H35/06
Filed: 1984-01-27
Abstract: PURPOSE:To match the cutting length of photosensitive paper continuously with the length of document by interlocking the selection switch of delay timer for varying the delay time with the function of means for switching the carry speed. CONSTITUTION:Upon start of paper feed through insertion of document, a document trailing edge detector 4 is enabled to detect passing of the trailing edge of document 1 through said detector 4. Consequently, the trailing edge detection signal holding circuit 31 will rise to set CR oscillation timer 32 thus to provide delay time of CR oscillation timer 32 matched with the carrying speed through the resistance preset by the selection switch interlocked with selection of carrying speed. Upon elapse of said delay time, a cutter drive control circuit 30 will function to start rotation of rotary cutter with predetermined time lag, to reset said circuit 31 and timer 32. When increasing the number of selection switches, the delay time can be set finely against the variation of carrying speed resulting in fine matching between the cutting length of photosensitive paper and the length of document.

IPC: F23D11/38
Filed: 1987-01-23
Abstract: PURPOSE:To permit the supply of fuel, including solid particles such as coal, water slurry (CWM) or the like, into a mixing chamber under the condition of atomization fine particles, by a method wherein either one fluid of the fuel, flowing through a mixing prechamber, having an annular section, in the state of a thin film, or atomization medium is injected into the other fluid. CONSTITUTION:A mixing prechamber 12 communicates with a CWM supplying passage 5 through a CWM flow passage 3b. When atomizing medium is injected into CWM, flowing through the mixing prechamber 12 from upstream side to downstream side, an atomized medium supplying port 10b is provided with a direction, in which the injecting direction of atomizing medium, injected into the mixing prechamber 12, has a component along the flow direction of the CWM, another component orthogonal to the direction of the same and the other component along the tangential line with respect to the large diametral inner peripheral wall 12b. Further, the atomizing medium supplying port 10b is directed to aime at the part of downstream side of a small diametral inner peripheral wall 12a or a downstream end side small diametral inner peripheral wall surface 12a1. Accordingly, the CWM, flowing in the state of liquid film, is split effectively by the force and moment of turbulence due to turbulent flow caused by the atomizing medium which flows in a high speed, whereby atomized fuel may be prevented from producing rough particles.
