Title: Etching of polyimide film
IPC: C08J7/00
Filed: 1992-03-31
Abstract: PURPOSE:To form high-accuracy holes in a polyimide resin film by etching by a method wherein a treatment process suitable for an etching reaction of the polyimide resin film is used. CONSTITUTION:A method of etching a polyimide resin film consists of a first etching process using an etching liquid containing an alkali metal hydride, such as a potassium hydroxide and a sodium hydroxide, and an alcohol, a first rinsing process subsequent to the first etching process, then, a second etching process using an alkali metal hydroxide aqueous solution. The process between the first and second etching processes is performed at least one time and thereafter, a second rinsing process is performed and at the same time, a treatment is performed on the polyimide resin film under ultrasonic irradiation in some process of the processes. Thereby, small holes having a diameter of 100mum or shorter can be formed in the resin film with high accuracy.

Title: Manufacture of recording medium
Inventor: KOFUKADA MIEKO
IPC: G11B5/852
Filed: 1987-03-30
Abstract: PURPOSE:To permit initial magnetization simultaneously with film formation and to improve productivity by impressing a magnetic field to the surface of the film forming side of a substrate at the time of preparing a magnetic film on the substrate. CONSTITUTION:A sheet-like permanent magnet 2 is disposed on the surface on a substrate holder 1 to be mounted with the substrate 3. The magnetic flux density generated on the film forming side of the substrate 3 is maintained at about >=300Oe or >=5 gauss by this permanent magnet 2. The magnetic moment of the particles arriving at the substrate 3 at the time of forming the magnetic film having perpendicular magnetic anisotropy is directed by the magnetic lines of force of this permanent magnet 2 and the magnetization as the thin film is directed in the same direction and, therefore, the initial magnetization of the perpendicularly magnetized film is executed simultaneously with the film formation. The initial magnetization simultaneously with the film formation is thus permitted with the magnetic films having any large coercive force without necessitating the special equipment and time for the purpose of the initial magnetization.

Title: Floor-heating device
Inventor: SEI MIKIO
IPC: F24D13/00
Filed: 1989-03-28
Abstract: PURPOSE:To make the use of the midnight power supply efficient in the use of a heat storage material for a floor heating device by making the upper half of the heat storage material thinner in thickness than the lower half. CONSTITUTION:Without altering the total quantity of a heat storage material 2, 3, the heat storage material forming an upper half 2 is made thinner in thickness than the heat storage material forming a lower half 3. Thus by forming the upper heat storage material 2 in a thinner thickness than the lower 1 without altering the heat-storing capacity, the resistance to the heat passing from the heater 4 to the room can be reduced, whereas the resistance to the heat passing from the heater 4 through the flooring downward is increased due to the increased thickness of the lower heat storage material 3. As a result, a heat storage material, for the same heat-storing capacity as a conventional one, warms up the room more efficiently and keeps the room more comfortable in the room temperature and in the temperature at the surface of the floor. When a conventional level suffices in heating effect, the heat stored in the heat storage material can be reduced.
