Title: Supporting structure for objective lens holder of optical head
Inventor: MORIFUJI HIROAKI
IPC: G11B7/09
Filed: 1986-12-29
Abstract: PURPOSE:To obtain a supporting structure for objective lens holder which can shift the frequencies that cause the secondary resonance to a high frequency band while maintaining the sensitivity characteristics, by forming a section shape with a rib at the middle part between the thin hinge parts of a support member in a structure where the objective lens holder is supported via the upper and lower sheets of support members set in parallel with thin hinge parts formed at both ends. CONSTITUTION:A current flows to a focusing coil 8 and the up-down driving force is produced. Thus an objective lens holder 2 moves up and down by the up-down bending deformations of both hinge parts 11b and 11c of a support member 11. In such focusing control action, a middle part 11a of the member 11 has the satisfactory rigidity despite a light weight owing to its section shape with a rib. Thus the deterioration of the sensitivity characteristics can be avoided with an actuator and at the same time the generation of vibrations can be prevented since the resonance point moves to a high frequency band.

Title: Bearing cup for universal joint
Inventor: FUKUSHIMA HIROSHI
IPC: F16D3/41
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent increase in the transmission torque of a needle bearing used in a universal joint and also dispersion of the transmission torque by precluding deformation of a cylindrical part and bottom part. SOLUTION: A bearing cup 6a is configured with two diametrically different parts, i.e., one part about the axial direction at the end part near the bottom 8 having a minor outside diameter (d) and the remainder having a major outside diameter D. Deformation of the bottom part 8 is suppressed even when press fitting is made into a circular hole provided in a yoke, and deformation of the cylindrical part 7 in association therewith is precluded. Thereby increase in the transmission torque of a needle bearing, whose raceway is the inside circumferential surface of the cylindrical part 7, and dispersion of the transmission torque are suppressed.

Title: Semiconductor memory backup circuit
Inventor: ITAGAKI KENJI
IPC: G06F1/26
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To surely back up a semiconductor memory without using a primary battery by using a super-capacitor and an electrolytic capacitor as the backup power supplies. SOLUTION: The power Vcc of a microcomputer 11 is supplied from a power supply +B via a diode 14. At the same time, a super-capacitor 12 serving as a backup power supply is fully charged up to +B1 with a time constant which is decided by the capacity of the capacitor 12 and the protective resistance 13. An electrolytic capacitor 20 serving as a backup power supply has no serial resistance and accordingly is immediately and fully charged with application of a power supply. If a main power supply +B is applied and then cut before the charging voltage of the capacitor 12 rises up to a reset voltage level, the memory of the microcomputer 11 is backed up the capacitor 20.

Five kinds of reference lengths Ax-Ex, Ay-Ey being set coaxially for each ordinate and abscissa correspond to five stage correction of the magnification at a microscope section having a zoom mechanism. The pattern is formed by depositing a substance, e.g. chromium, on a transparent substrate, e.g. a glass substrate, wherein the deposited part constitutes a dark part 50 (51-56) and the undeposited part constitutes a bright part 40 (41-45). The bright part 40 and the dark part 50 are formed by arranging a plurality of squares of different size concentrically and they are reversed along the diagonal a-b of the square.
