Title: Electrostatic rotary encoder
Inventor: SHIGEYAMA NAOKI
IPC: G01D5/24
Filed: 1991-12-03
Abstract: PURPOSE:To enable prevention of mispositioning due to dew condensation by providing a water absorber covering the periphery of the gap between a rotor and a stater. CONSTITUTION:Between a rotor 10 fixed on a rotation shaft 12 and a stater 1 fixed in a housing, there is a gap 3. A water absorber 2 consisting of felt and the like is bonded on the base plate of a stater 1 so as to cover the periphery of a gap 3. The water absorber 2 is formed to a C-shape having a notch at the bottom. When this is used in a high humidity environment, condensation dew 13 is caused on the stater 1 surface and flows on the stater 1 surface, which is absorbed by the absorber 2. Thus, the invasion of the condensation dew 13 into the gap 3 is prevented. If the water exceeds the capacity of the absorber 2, the water 4 drops out of the notch formed at the bottom and is exhausted. Also, the air invasion into the gap 3 is prevented by the water absorber 2 and so dew condensation in the gap 3 hardly occurs.

Abstract: PURPOSE:To satisfy both the selection of a flattening material resisting the annealing temperature of a thin-film pole and easy flattening by depositing low melting-point glass having the melting point same as or higher than the annealing temperature of the thin-film pole on the stepped surface of the thin- film pole and a thin-film coil only in required thickness and heating a glass deposited surface up to a temperature, where glass is melted. CONSTITUTION:Low melting-point glass as a first insulating layer 61 is deposited on the surface of a magnetic gap spacer 3 patterned onto a non-magnetic substrate 1. When the first insulating layer 61 is heated at a temperature, where glass is liquefied, glass is melted and liquefied, and the surface of glass is changed into a shape determined by surface tension regardless of the irregularities of the lower pole 2, etc., at the lower section of glass, i.e., a glass-film surface shape 11 after a reflow. When glass is cooled up to room temperature under the state, glass is solidified as glass is left as it is formed in the glass-film surface shape 11 after the reflow. Consequently, the first insulating layer 61 is flattened. Glass having the melting point higher than the annealing temperatures of the lower pole 2 and an upper pole 4 by 50-100 deg.C is selected, thus annealing an upper pole material without trouble.
