Title: Manufacture of semiconductor device
Inventor: TORII YASUSHI
IPC: H01L21/306
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To raise the inside evenness of a metal film and to attain the stability of polishing by a method wherein when the metal film is polished, an oxide on the surface of the material to be polished is removed before the polishing in order to shorten the latent period in which polishing rate is extremely low, which is generated immediately after the start of the polishing. SOLUTION: A pattern is formed on a semiconductor wafer by a patterning 15 then a metal film is formed by a metal film forming process 16. In this case as a surface layer removing process 17, an alkaline or neutral slurry is used in the first polishing stage, and an acidic slurry is used in the second polishing stage. A tungsten film is formed on a polished wafer by a CVD method, for example. As the slurry in the first stage, one which has a pH about 10 to 12 adjusted with an ammonia or the like, and contains about 10% of silica as abrasive grains, is used. As the slurry in the second stage, one which contains an oxidizing agent, such as water hydrogen peroxide solution, has a pH prepared in 2 to 4 and contains 5% or thereabouts of a silica as abrasive grains, is used.

Title: Electromotive power steering device
Inventor: UEDA YOSHIHIRO
IPC: B62D101/00
Filed: 1991-12-02
Abstract: PURPOSE:To improve the operation feeling by providing a control means to correct the assist instruction value according to an inertia control signal and a inertia control signal, and to control the drive of an assisting motor. CONSTITUTION:A torque sensor signal process is applied so that a signal made by removing a vibration component from the output signal of a torque sensor 11 is used when an assist force is generated in case of steering a handle, while a signal including the vibration component to the output signal of the torque sensor 11 is used when a vibration owing to the rigidity of the torque sensor 11 is controlled. As a result, a phenomenon to generate a resonance owing to the rigidity of the torque sensor 11 between an assist motor 6 and a handle at both of the torque sensor is prevented, and by preventing the transmission of the resonance to the steering assist torque, a good steering feeling can be obtained, as well as a sufficient rigidity compensation can be given.

Title: Thick paste
Inventor: KOIWA ICHIRO
IPC: H01J17/04
Filed: 1989-12-28
Abstract: PURPOSE:To form a highly precise conductor pattern difficult to cause concentrated discharge by a thick paste by forming the thick paste by use of conductive particles and a liquid organic resin. CONSTITUTION:The use of a liquid organic resin as a binder allows the connection of particles with a base or particles to each other by a small quantity of the binder even when the particles are refined. The particle density in the formed conductor pattern can be increased by reducing the binder amount. As the conductive particles, metal particles are used, and the thermosetting temperature of the liquid organic resin is desirably lower than the oxidation temperature of the metal particles, whereby the conductor pattern is formed without oxidation of the metal particles. Further, the particles are preferably conductive metal oxides, whereby no possibility of firing by refining is eliminated, and fine particles can be produced at low costs.

Title: Manufacture of spring having same pole repulsion multifunction by magnetic force
Inventor: TADOKORO MASAHIDE
IPC: F16F6/00
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic force spring which is repulsed and shrunk, generating same pole on a spiral part of N-pole and S-pole by magnetizing a flat steel wire and thereby generating the N-pole and the S-pole, and forming the magnetized steel wire like a spiral. SOLUTION: A flat magnetized steel wire is formed into a tubular spiral. The spring is characterized by a flexible repulsion and shrink motion to a certain load (compression). When more load than certain range is loaded, the characteristics that the repulsion is reduced by the load loaded turning force direction the compression direction and the self-control acts thereby, exists therein. When the load is overloaded on the spring, repulsion force is lost and only compression force acts. The same pole on the spiral part sidappears and thereafter two poles of N-and S-pole remain, and N and S attract each other and then the spring becomes into coiled state and compression force acts strongly. Thus, This spring becomes into the spring having a self-characteristics of same pole repulsion multifunction by magnetic force.
