Filed: 1988-01-29
Abstract: PURPOSE:To shorten a system down time and to improve the continuation of a job by reloading all characters in a character pattern or a font pattern on an error generating position when a parity error is generated in a font memory using a DRAM. CONSTITUTION:When a parity error is generated in the font memory, a printer control part PC informs font memory parity error detecting data and a font address generating the error to a host computer 1. At the time of operator's recovery operation, the host computer 1 automatically reloads the reported font address and font pattern to the printer control part (PC) and outputs reprinting data from printing data in a page generating an error to execute reprinting. Consequently, a job about the contents of an error such that the content of the memory in a DRAM constituting the font memory are volatilized can be continued without turning off power for the printer control part PC and charging load to the operator.

Title: Wafer prober
Inventor: YASUDA TOSHIMI
IPC: H01L21/66
Filed: 1985-01-31
Abstract: PURPOSE:To improve the production efficiency by a method wherein normal chips only are subject to measurement inspection avoiding the measurement of any chips in effective sections wherein no chips are formed despite the same space as that of normal chip sections. CONSTITUTION:Solid lined sections, broken lined sections and outside sections represent respectively normal chips 14, effective sections 13 and ineffective sections 12. Next an x, y plane coordinate system is assumed to place a wafer 11. When a measurement inspection is to be performed in +y direction from lefthand upper corner of the wafer 11, a wafer stage is shifted to a measurement position by a command from a controller to measure firstly a chip 20 in the effective section 13. As it is evident that any preliminarily known coordinate values coincide with the data stored in a memory, the controller informed of the chip 20 to be in the effective section 13 measures the first chip 15 as the next one. In this case a nominal comparison is made of the data again since the coordinates of chip 15 is preliminarily known. At this time, the measurement inspection shall be performed since the chip 15 is known to a normal chip having no data coinciding therewith. Resultantly, any useless measurement of chip 21, 22 such as those in the effective sections may be avoided by means of repeating said procedures.

Inventor: SHIMIZU NORIYASU
IPC: B05B1/18
Filed: 1990-01-30
Abstract: PURPOSE:To freely adjust the amount of water discharged from a shower at a hand by the required amount by rotating a drainage head to adjust the flow rate of the shower. CONSTITUTION:When a movable member 11 is energized with a spring 16 and positioned to the lowest position, the valve part 15 of a rubber valve 14 touches the valve seat 10 of a pipe 7. Since the interval between a first flow path 17 and a second flow path 18 is interrupted, water is not discharged from a drainage head 5. Then when this head 5 is rotated, the pipe 7 fitted to the head 5 follows the rotation thereof and is rotated. The movable member 11 which is slidably touched to the cams 8a, 8b of the pipe 7 via arms 12a, 12b resists elasticity of the spring 16 and is raised. Therefor the valve 14 is elevated and a gap is caused between the valve part 15 and the valve seat 10 of the pipe 7. The interrupted interval between the flow pathes 17, 18 is released. Therefore, water in the flow path 17 is allowed to flow to the direction of the flow path 18 and passed through a third flow path 19 and discharged as shower from the small holes 6 of the head 5.
