Title: Removal of resist residue
Inventor: SUGANO ITARU
IPC: H01L21/304
Filed: 1991-12-02
Abstract: PURPOSE:To enable removal of resist residues without corrosion of wiring films by washing with pure water mixed with an oxidizer after washing with an organic solvent and an acid alkaline chemical and then by drying. CONSTITUTION:A semiconductor substrate is overlaid with an insulating film 8, and a contact hole 10 reaching a wiring film 6 on an insulating film 5 is formed. At this time, for removal of produced resist residues, washing is conducted with pure water mixed with an oxidizer such as oxygen gas or ozone gas after washing with an organic solvent and an acid alkaline chemical. This process causes the wiring film 6 to be surfaced with an aluminum oxide film 17 upon contact with water, which film suppresses corrosion of the wiring film. Washing in a dark free of light under a low temperature of 0-10 deg.C further reduces corrosion reaction.

Title: Magnetic reading and writing head
Inventor: MARC RYAT HENRY
IPC: G11B5/455
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a method by which it is detected that one side of terminals of a magnetic reading and writing head is connected to ground or is an open state by connecting a comparator circuit to a magnetic reading and writing head first and connecting it in parallel with a resister second. SOLUTION: When one side of terminals 8, 9 of a component 1 of a magnetic reading and writing head is not connected to terminals 14, 15 of a head, a current is not made to flow in an internal series resistor 3. A parallel connection resistor 6 has only a function to make a bias current I1 pass through. Large voltage drop I1×Rd is caused by a bias current I1, but this bias current causes voltage drop I1×Rd×Rh(Rd+Rh) in other state (Rd is a value of the parallel connection resistor 6, Rh is a value of the resistor 3). If a value Rd is sufficiently larger than a value Rh, when a head is in an open state, voltage drop in both ends of the parallel connection resistor 6 is increased largely. These increasing of voltage drop is used for switching a comparator 7.

Title: Variable resistor
Inventor: KOIZUMI YOICHI
IPC: H01C10/32
Filed: 1989-12-08
Abstract: PURPOSE:To prevent backlash by setting the hardness of the outer periphery of an elastic O-ring to a value lower than that of the center, and suppressing its distortion to a small value. CONSTITUTION:An elastic O-ring 8 is interposed, similarly to prior art, between a resistor board 5 and a rotor 2. The hardness of the outer periphery 8a of the ring 8 is set to a value lower than that of the center 8b. Accordingly, deformation of the ring 8 due to a frictional force between the rotating rotor 2 and the ring 8 can be prevented. Thus, returning repulsion force of the rotor 3 due to the distortion becomes very small, and the rotor 2 can be held at a set position. Thus, a backlash can be prevented.
