Patent JP-H0191422-A (JP)
Title: Formation of fine pattern
Inventor: HASHIMOTO KAZUHIKO
IPC: G03F7/095
Filed: 1987-10-02
Abstract: PURPOSE:To inhibit the reflected electrons of an electron beam from a substrate and to make it possible to inhibit a proximity effect by a method wherein fine patterns are each formed into a two-layer resist structure of a P-type resist and an N-type resist. CONSTITUTION:A CMS layer, which is an N-type resist, and a PMMA Si layer, which is a P-type resist, are respectively coated as a lower resist 2 on a semiconductor substrate 1 and as an upper resist 3 on the substrate 1. When an electron beam 4 is exposed on the resist 3 at the optimum amount of exposure, the exposed beam 4 sensitizes the resist 3 and reaches the resist 2 while losing its energy. As the CMS of the resist 2 absorbs electrons, the electrons to reach the substrate 1 are decreased. Thereby, the reflected electrons from the substrate 1 are also decreased and a proximity effect can be inhibited.

Title: Press-in erection method for piles
Inventor: TERASAKI SHIGEKI
IPC: E02D7/20
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To reduce the friction force of a pile peripheral face by cement milk to press piles in by pressing the pile into ground while the cement milk is jetted from the edge part of the pile. SOLUTION: The pile 12 is pressed in ground while the cement milk 1 is jetted from the tip part of the pile 12. Blending of the using cement milk preferably uses the water and cement ratio of 60-150% in the weight ratio of water and cement. Thus, the peripheral ground of the piles is disturbed as well as a conventional water jet by utilizing the flowing time band of the cement milk 1, and the pile 12 can be pressed-in in a state where the friction force of the pile peripheral face is reduced. Since the piles need not be large-sized or it need not deal with the increase of the number of the piles, the piles can be economically pressed in and erected in a single process in pile foundation comparatively large in support force by the comparatively small-sized piles without increasing the construction cost of the pile foundation.

IPC: G06F7/499
Filed: 1986-10-21
Abstract: PURPOSE:To easily and quickly detect a pattern that is delayed in terms of speed by adding an edge detecting circuit to an adder of a semiconductor logic circuit that detects errors of a digital computing element like a synchronizing adder, etc. CONSTITUTION:The sum or carry signal I received from a full adder that is supplied to an input terminal 16 of an edge signals detecting circuit is changed to H from L or vice versa. Under such conditions, the signal S delayed by two inverters 5 and 6 is supplied to an XOR gate 17 with a slight delay of time compared with the signal that is supplied directly to the gate 17. Thus, the input of the gate 17 is set at H and L by a degree equal to said delay time and the signal (a) supplied from the gate 17 is kept at H in this due period. This signal (a) is supplied to the set terminal of an RS.FF circuit 9 and an output signal O is set at H. In such a way, the edge signal detecting circuit is added to an adder and set at plural bits. Thus H is supplied to an OR gate 1 and an output terminal 2 dlivers H when just one of those full address connected to the edge signal detecting circuit is delayed in terms of speed and the data is changed. Thus an error of the edge detecting circuit can be detected.
