Title: Forming method of wiring
Inventor: HIRAIDE SEIJI
IPC: H01L23/52
Filed: 1990-11-24
Abstract: PURPOSE:To prevent the increase of contact resistance, by forming a plurality of series type silicide wiring layers mutually connecting impurity-doped regions of different conductivity type, by a wiring formation processing conducted for a plurality of times, so as to come into contact with each other while mutually interposing grain boundaries. CONSTITUTION:Silicide is deposited on an insulative film 16 so as to cover a first silicide wiring layer 18A and a contact hole 16B. By patterning, a second wiring region 18B which comes into ohmic contact with an impurity-doped region 14 and comes into contact with the first silicide wiring layer 18A via a grain boundary GB is formed. After that, the first and the second silicide wiring layers 18A, 18B are subjected to heat treatment. Since silicide grains form a discontinuous surface on the grain boundary GB, P-type or N-type impurities sucked up from an impurity-doped region 12 or 14 are prevented from diffusing by the grain boundary GB. Thereby low contact resistance can be obtained in the contact part of the impurity-doped region 12 or 14.

Filed: 1988-12-20
Abstract: PURPOSE:To cool partially any part subject to high temperature at low cost by installing a ventilation pipe connected with the outside to a frame in which a heating element is laid out, and ejecting open air into a place to be cooled. CONSTITUTION:As heating elements 3 and 4 are under the shade of a large heating element 2 which stands in the way of an air supply port 6, the flow of air tends to stagnate and get subject to high temperature. A nozzle of a ventilation pipe 9 connected with an air supply duct 8 is bored in its upper part so that a cooled air may be brought into direct contact to reduce the temperature. The space between the heating element 4 and a heating element 5 laid out behind is distant from either the air supply port 6 or an exhaust air port 7, and they are laid out at the corner of a frame 1. When the flow of air is subject to stagnation, the stagnated air can be removed by laying out a nozzle 12 of a ventilation pipe 10 connected with an exhaust air port 7, thereby promoting cooling operation.

Abstract: PURPOSE:To produce a table of a large size within a limited memory capacity by providing a row control table, a column control table, a table control means, etc., and improving the storing method of the ruled line data into a memory. CONSTITUTION:The ruled line data inputted from an input means 4 is written into a control information area of a row control table 2 according to the instruction of a pointer set on a column control table 3 under the control of a table control part 14. When the ruled line information number is written into a control information area in accordance with a control information format 12, the ruled line data is compressed and stored. That is, the same types of vertical ruled lines are vertically continuous at the positions of a 1st column on the N-th, (N - 1)th and (N + 1)th rows. Thus the data are compressed and stored in a ruled line information area (1) of the 1st column of the table 2 based on the ruled line data on both start and end rows. In the same way, the are also compressed and stored in the 1st and (N + 1)th rows of the M-th column. Thus it is possible to produce a table of a large size with the small memory capacity and to improve the freedom of memory application. Then the table is effectively used.

Title: Paper feed method
Inventor: TAMAKOSHI YASUHIKO
IPC: B41J25/308
Filed: 1987-12-18
Abstract: PURPOSE:To eliminate the possibility that a head is caught by a paper stapler even if the head is overlapped with the paper stapler to prevent the occurrence of paper jamming, by a method wherein, the head is moved backward by a fixed amount in a paper feeding, if the paper is a continuous document having a large paper thickness. CONSTITUTION:A paper thickness is detected by the step count of a pulse motor 9, and according to the detected paper thickness a head gap is adjusted. When a paper is fed after the head gap adjustment, whether the paper is a tractor paper is identified. If it is a tractor paper, whether the paper thickness detected at the head gap adjustment is larger than a fixed value is identified. If the paper thickness is larger a fixed value, a head is moved back by a fixed amount and, thereafter, the paper is fed and the head is returned to the former position. In this manner, since the head is moved backward by a fixed amount in a paper feeding with use of a continuous document having a large paper thickness, the possibility that the head is caught by a paper stapler is eliminated even if the head is overlapped with the paper stapler to prevent the occurrence of paper jamming.
