Title: Manufacture of resin-bonded magnet
Inventor: ITO NOBORU
IPC: H01F41/02
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To prevent generation of dioxide in natural decomposition or incineration in the case of discarding by mixing bio-decomposable plastic as a binder into magnetic powder and molding it through extrusion molding, injection molding, calender molding, or compression molding and high pressure molding and mgnetizing it. SOLUTION: Bio-decomposable plastic or non-halogen resin containing no chlorine as a thermoplastic resin, or a thermoplastic resin obtained by mixing them is mixed as binder into magnetic power. The mixing ratio of the thermoplastic resin to the magnetic power is that the thermoplastic resin as the binder is not more than 45% of total weight at least at the stage of molding a resin- bonded magnet. The mixture of the thermoplastic resin and the magnetic powder is heated and softened to be molded into the resin-bonded magnet by extrusion molding, injection molding, calender molding, or compression molding and high pressure molding. Further, ferrite magnetic powder, or alloy magnetic power containing rare earth element such as Sm, Nd, Ce, Pr, etc., or a mixture of these magnetic powders is used as the magnetic powder.

Title: Automatic focusing device
Inventor: MOTOTSUGU RIYUUZOU
IPC: G02B7/36
Filed: 1980-07-18
Abstract: PURPOSE:To speed the operation of a motor and to improve focusing precision by providing a means of varying the turning speed of the motor with the pulse width of a pulse signal and of prescribing the minimum limit of the pulse width. CONSTITUTION:Signals inputted from a focus detector to input terminals 1 and 2 are converted by comparators 3 and 4 into rectangular wave signals A and B. For example, the signal B leading the signal A in terms of phase. In this case, the signals A and B are inputted to an EX-OR gate 6, which supplies a phase difference signal C to an OR gate 10. The signals A and B are passed through an OR gate 7 to operate monostable multivibrators 8 and 9 by the signal B. The output E of the monostable multivibrator 8 is inputted to an OR gate 10, whose output signal H has pulse width greater than that of the signal C. The output signal F of the monostable multivibrator 9, on the other hand, serves as the clock signal of an FF11 to latch the signal C. The signal H and G are ANDed by an AND gate 12, whose output is inputted to an EX-OR gate 13, thereby controlling focusing by flowing a current IM, which depends upon a difference voltage K from a signal J from an FF5, to a motor M. Consequently, the speed of the motor is increased and focusing precision is improved.

Title: Apparatus for stabilizing magnetic field sensor
Inventor: BIITO HEERUKU
IPC: G01R33/06
Filed: 1989-04-19
Abstract: PURPOSE: To reduce the influence of instability of an electric charge carrier concentration to the long period stability of a magnetic field sensor by correcting efficacious output signals in use of the electric charge carrier concentration of a semiconductor material and time changes of the electric charge carrier concentration. CONSTITUTION: An amplifier 3 functioning as a correction circuit in input circuits 2,3,8 relative to a magnetic sensor l multiplies an electric current (i) applied to the magnetic field 1 by a correction factor being in proportion to the factor (1+δn /n) (where, (n) is the electric charge carrier concentration of a semiconductor material, δn is the time change of the electric charge carrier concentration). That is, in this Instance, the output voltage UV of the amplifier 3 is in proportion to (1+δn /n), thus the current (i) is in proportion to a product uN.(1+δn /n). Accordingly, even if time concentration changes take place in the electric charge carrier concentration of a semiconductor material, the changes are corrected at all times.

Title: Formation of solder bump
Inventor: YAMADA TAKESHI
IPC: H01R43/02
Filed: 1987-04-20
Abstract: PURPOSE:To ensure insulation between solder bumps, by forming electrode thin films on a semiconductor chip, spin coating photosensitive polyimide all over the surface, exposing only the electrode thin films by photoetching, vapor depositing a bump forming metal thereon and removing the polyimide film. CONSTITUTION:Electrode thin films 5 are formed on the surface of a chip formed on a silicon wafer. Photosensitive polyimide 6 is applied thereon by spin coating technique. After ultraviolet radiation is applied to the regions corresponding to the electrode thin films 5, the polyimide is developed to expose the electrode thin films only. A metal mask 7 having windows at the positions corresponding to the electrode thin films 5 is positioned thereon and indium 8 is vapor deposited. Removing the metal mask 7, there appear indium sections 8 connected by the polyimide 6 and arranged in matrix. The polyimide 6 is then peeled off and solder bumps of indium are obtained. Any indium 8 deposited on the polyimide 6 will be molten and removed together with the polyimide 6. Therefore, defect in insulation can be prevented completely.

Abstract: PROBLEM TO BE SOLVED: To simply fitt and detach an adjusting tool to a pillar and quickly adjust the height by providing a C-shaped or semicircular holding part detachably fitted to a pillar formed out of elastic material, and an engaging hole projecting inward from the holding part or a projecting body for locking an engaging recessed part. SOLUTION: This pillar height adjusting tool 10 can be mounted to an inner pillar 12 formed into a columnar shape easily and surely, because the holding part 15 is formed into a C-shape. Further because the holding part 15 is formed out of synthetic resin material having elasticity, the end parts 15 can be spread right and left, and hence the fitting and detaching work to the inner pillar 12 can be easily executed. Because the locking part 16 is formed into a projecting shape capable of being fitted in an engaging hole 13, by only fitting the locking part 16 into the engaging hole 13 when the holding part 15 is mounted on the inner pillar 12, an outer pillar 11 can be surely locked with the inner pillar 12. Further because a knob part 17 for fitting and detaching is provided, the fitting/detaching work can be quickly executed.
