Title: Manufacture of soft magnetic film and magnetic head
Inventor: NAKO KUMIO
IPC: G11B5/147
Filed: 1992-05-26
Abstract: PURPOSE:To obtain a soft magnetic film having a high saturated magnetic flux density and low magnetostriction by forming the film having a composition containing Fe as a main ingredient and predetermined amounts of N and an element of a set composition while applying a bias of a predetermined value to a board for forming the film. CONSTITUTION:A soft magnetic film having a composition containing Fe as a principal ingredient and 5-20 atomic% N and 5-15 atomic % M is formed by using a mass production sputtering apparatus of the type in which a target 8 and a board 7 are opposed in parallel. The M of this case is at least one or more types of elements of Ta, Zr, Hf, Nb and Ti. When this Fe-M-N film is formed, the forming is carried out while a low negative bias of 150-2780W/cm2 is applied to the board 7. Thus, the film having high saturated magnetic flux density, low magnetostriction and isotropic high permeable characteristics is obtained with high mass productivity.

Title: Fuel supply controller of internal combustion engine
Inventor: KITAJIMA SHINICHI
IPC: F01N3/24
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To appropriately control the initial timing of feedback control corresponding to the oxygen content sensor output on the downstream side of a three-way catalyst, when an internal combustion engine provided with a three- way catalyst and an NOx absorbent in the exhaust system shifts from an operating state which initiates lean control to an operating state which should initiate feedback control to the stoichiometric air-fuel ratio. SOLUTION: When an engine shifts from an operating state which initiates lean control to an operating state which should initiate the feedback control to the stoichiometric air-fuel ratio, the start of feedback control corresponding to the output of an O2 sensor is delayed only the delay time TMFBDLY (S22). While the air-fuel ratio is made richer in order to reduce NOx absorbed in the NOx absorbent, the delay time TMFBDLY is reduced only the time TMDEC corresponding to this time to make the air-fuel ratio richer (S18).

Title: Magnetic field sensor using liquid crystal and three- dimensional animation recording and reproducing device using it
Inventor: OKAMOTO KOICHI
IPC: G01R19/00
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To record and reproduce the three-dimensional animation by a single device. SOLUTION: Liquid crystal molecules are aligned by applying a DC voltage to both transparent electrodes holding the liquid crystal therebetween. When light enters cells, the liquid crystal changes its orientation direction by the electric field of the light. The change of the orientation is detected as the change of the electrostatic capacity of the electric resistance between both electrodes. A liquid crystal panel 35 formed by two-dimensionally aligning the liquid crystal cells is used as an image sensor, an interference pattern of an object 38 is detected at a real time to record the three-dimensional animation. The data of the recorded three-dimensional animation is reproduced by the same liquid crystal panel 35, and the three-dimensional animation is reproduced by applying the reading light.  The laser beams from the laser light sources of three primary colors are successively switched by a beam chopper to form the interference pattern, whereby the color three-dimensional animation is recorded. The color three-dimensional animation is reproduced by reproducing the interference pattern in synchronization with the chopping in recording, and applying the laser beam of the same color.
