Title: Magnetic field measuring method
Inventor: ANDO HISAHIRO
IPC: G01D5/245
Filed: 1988-12-28
Abstract: PURPOSE:To measure a magnetic field while maintaining detection sensitivity by arranging a magnetoresistance effect element while its magnetism sensing surface faces a magnetic pole surface and is displaced from the center position of the magnetic pole at right angles to the moving direction of the magnetic pole. CONSTITUTION:The magnetism sensing surface of the magnetoresistance effect element 11 is set opposite the outer peripheral surface of the magnet 18 and also displaced by a specific distance from the magnetic pole center of N poles 18a and S poles 18b along the axis of rotation of a cylindrical magnet 18 in order to detect the rotation of the cylindrical magnet 18. The traveling direction of a magnetic field produced by the N magnetic pole 18a is vertical to the magnetic pole surface in the center of the magnetic pole, but slants along the magnetic pole surface at a position shifting from the magnetic pole center along the axis of rotation of the magnet 18 and the tilt angle decreases with the displacement distance from the magnetic pole center. Therefore, the magnetic field which is cross-linked with the element 11 operates effectively along the magnetism sensing surface. Consequently, the element 11 can detect a magnetic field component of the cross-linked magnetic field in the magnetism sensing surface direction.

Title: Pen made of synthetic resin
Inventor: FUKUDA MASAO
IPC: B43K1/02
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To inhibit the occurrence of a trouble that writing can not be conducted due to clogging of an ink passage, by a method wherein the length of a small-diameter part in the longitudinal direction is made larger than that of a slit in the longitudinal direction. SOLUTION: The fore end part of a pen is a small-diameter part 3 formed by shaving off a covering part 2 and a slit 4 is formed in a part about 1/2 of this small-diameter part from the fore end thereof. The slit 4 is formed by immersing the fore end part in a swelling liquid for a material of a pen. When the fore end part of the pen is immersed in the swelling liquid, in other words, an opening part of an ink passage 1 is expanded due to swelling of the fore end part, a wall part forming the ink passage 1 is thereby split and the slit 4 is formed. When the fore end part of the pen is worn with writing and the small-diameter part 3 becomes short, the position of a support point of a writing load shifts therewith and a split length of the slit 4 increases as well.  In this way, the length of the slit 4 is maintained in a certain degree and a function of removing dust is prevented from lowering with passage of time.

Title: Screw mechanism
Inventor: TOYOFUKU MASANORI
IPC: F16H25/24
Filed: 1994-12-17
Abstract: PURPOSE: To stably obtain accurate and rattleless position-adjustment only by changing a screw pitch either of an internal thread or of an external thread by bringing into a special relation the pitch of internal thread and that of external thread in addition to the number of engaged screw-threads and the screw pitch of either internal thread or external thread. CONSTITUTION: With respect to a pitch-difference between the pitch of an external thread 11 and that of an internal thread 12, a pitch Pn, which is different from an ordinary pitch(P), is given to either one of the external thread 12 or the internal thread 12. In this case, applying this special pitch Pn to the thread on either one side only will suffice the purpose. The pitch-difference like this can be obtained by equally dividing the backlash TL in the advancing direction by a value corresponding to the number of engaged screw threads. The backlash TL in the advancing direction is determined from a difference between the maximum limit of size and the minimum limit of size at the effective diameter of the external thread 11 and the internal thread 12, which are specified according to the classification of the thread.  Since the angle of thread is specified as 60 degrees here, the pitch-difference is obtained as (the maximum limit of inside diameter of the internal thread 12 minus the minimum limit of outside diameter of the external thread 11)÷3<0.5> /N. The special pitch Pn can be obtained by adding this value to each pitch(P).
