Title: Thermal transfer printer
Inventor: SASAKI AKIRA
IPC: B41J2/335
Filed: 1986-07-30
Abstract: PURPOSE:To prevent a transfer ununiformity due to the ink missing of a center of the printing dots by constituting the title device in such a manner that a temperature distribution curve of the surface of a heating element may be almost analogous to a surface pressure distribution of the surface of a heating element. CONSTITUTION:A glazed part 28 has an almost semicircular shape before processing as shown by a broken line 29. In the first etching, the part is to be cut upto a place indicated by a broken line 30. At that time, the top is 180mum wide (W). Then it is to be cut upto a place shown by a broken line 31 in the second etching. The top is 100mum wide (W2). After the etching process, a protective member is removed, and a heating element 24 is provided on the top with the width of W2 which is sufficient. The place in which the heating element 24 is provided has a protrusion with a small radius, so that a pressing force, i.e. a surface pressure rises sharply and the temperature is distributed analogously to the surface pressure. The ink transferred from an ink ribbon to a paper to be transferred in uniformly frozen to be hardened over the entire length of the heating element without ununiformity with any time. Thus the ink is never retransferred to the ink ribbon.

Title: Fabrication of resist pattern
Inventor: KUMAGAI AKITOSHI
IPC: H01L21/027
Filed: 1983-09-28
Abstract: PURPOSE:To perform the fine processing with a high sensitivity by a method wherein when the positive electron beam resist spread over a substrate is irradiated with a beam to form a latent image followed by development to form a pattern, the treatment is done by use of a developing solution having a strong solvent power to leave the resist at the bottom of a recess and then a developing solution of a gentle solvent power is used to form the pattern. CONSTITUTION:A substrate 1 is coated with a film to be processed 2 and is covered with a positive electron beam resist film 3 having the thickness enough to prevent a pin hole followed by baking after which irradiation with an electron beam 4 is made only for a necessary part. Thus a backbone of the film 3 which is irradiated with the beam 4 is cut to make it low-molecular thereby increasing solvent properties for a solvent. Then it is developed by using a developing solution having a strong solvent power such as methyl isobutyl ketone and a recess 5 is formed on the film 3 at the bottom of which the film 3 remains. After that, a developing solution of a gentle solvent power such as a methyl isobutyl ketone-isoamyl acetate mixing solution is used to remove the film 3 left at the bottom of the recess 5.

Title: Non-bearing wall and construction method thereof
Inventor: OKAMOTO SUNAO
IPC: E04B2/88
Filed: 1993-07-19
Abstract: PURPOSE:To construct a non-bearing wall which is light and easy and inexpensive for its construction and also soft and restorable. CONSTITUTION:In a concrete non-bearing wall 4 connected to a structural frame work through connection rods 6, the connection rods are hollow connection rods that chemical fibers are woven so as to make a hollow braid. When constructing a non-bearing wall, concrete 9 is previously charged in both ends except the middle in the hollow hole 8 of hollow connection rods and concrete is placed in the surroundings of the structural frame work and the distributed bars. Then a non-bearing wall can be obtained, which absorbs well the horizontal deformation conducted from the structural framework and hardly breaks. Since the connection rods are light and have the coarse surface of braids at the peripheral face thereof, the workability is good and the adhesiveness with concrete and anticorrosiveness can be secured and also an inexpensive non- bearing wall can be constructed. And further, a simple and inexpensive non- bearing wall can be constructed with hollow connection rods by charging concrete at both ends except the middle of the connection rods.
