Title: Electron beam lithography method
Inventor: SAKAMA ISAO
IPC: H01L21/027
Filed: 1988-01-25
Abstract: PURPOSE:To improve working size accuracy for a lithography figure size by dividing the lithography figure by a base state of a lithography region. CONSTITUTION:A groove formed by lithography figure 2 having 1.0mum of width, 10.0mum of length and 4.0mum of depth for reducing reflected electron quantity is formed in lithography figures 1, 1' having 0.3mum of width and 5.0mum of length on an Si substrate. Further, protrusion step difference of 0.4mum for increasing the reflected electron quantity with 0.5mum of width and 10.0mum of length is formed by a lithography figure 3 in the figure 1. The superposed part of the figure data of the figures 1, 2 is identified. Thus, the figures 1, 1' are divided into dividing lithography figures 4, 4', 5, 5', 6, 6'. Then, when the superposed parts of the figure data of the figures 4-6 with the figure 3 are identified, the figure 6 is divided into dividing lithography figures 7-9. Optimum electron beam radiation amounts are applied separately to the divided lithography figures, thereby improving the working accuracy for the lithography figure size.

Title: Ion detector
Inventor: KATO KENICHI
IPC: G01R29/24
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To provide an ion detector which can selectively detect cations or anions generated from an ionizer. SOLUTION: When negative charges are collected by means of a collecting electrode 11, a capacitor 15 is charged through a closed loop formed to the capacitor 15 from the electrode 11 through a grounding electrode 13 at a time constant which varies depending upon the capacitor 15 and a variable resistor 19. Since a diode 21 is reversely biased, the charging current does not flow through the diode 21. When the charged voltage of the capacitor 15 reaches the discharge voltage of a neon lamp 17, the lamp 17 discharges at the above- mentioned time constant. When the electrode 11 collects positive charges from cations, the capacitor 15 is not charged and the lamp 17 does not discharge, because the diode is normally biased against the current from the electrode 11 and the current from the electrode 11 flows through the diode 21.

Filed: 1995-01-31
Abstract: PURPOSE: To restrain a drop in a drain capacity resultant from fallen leaves or trashes by installing a flowing water guide cylinder which is provided with a trash keep-off pieces. CONSTITUTION: Fallen leaves or trashes, which flow in from the lateral side of keep-off pieces 7 in a rainwater passage are collided with the keep-off pieces 7 and remain in an adjustable drain main body 1, thereby narrowing the rainwater passage. More specifically, fallen leaves and trashes remaining around a flowing water guide cylinder 4 hinders a drainage capacity of the rainwater passage. Even in this case, however, an auxiliary guide cylinder 4a is hangingly installed to the flowing water cylinder 4 continuously in the passage where rainwater flows in past the flowing water guide cylinder 4, thereby preventing trashes from being deposited easily.  Therefore, even the drainage capacity of the rainwater passage which flows in the main body 1 passing by the refuse keep-off pieces 7 is degraded, another flowing water guide cylinder maintains the drainage capacity of the rainwater passage and minimizes the number of cleaning operations.
