Title: Optical pickup device
Inventor: ARAI NORIKAZU
IPC: G11B7/135
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To enable the recording/reproducing of plural optical information recording media varying in thicknesses with one condenser optical system by making the magnification viewed from the optical information recording medium side of an objective lens at the time of the recording or reproducing of the information of the second optical information recording medium smaller than the magnification viewed from the optical information recording medium side of the objective lens at the time of recording or reproduction of the first optical information recording medium. SOLUTION: The magnification viewed from the second optical disk 20' side of the objective lens 16 at the time of the recording/reproducing of the second optical disk 20' is made smaller than the magnification viewed from the first optical disk 20 side of the objective lens 16 at the time of the recording/reproducing of the first optical disk 20. Namely, the dispersion degree of the incident luminous flux on the objective lens 16 is varied at the time of the recording/reproducing of the first optical disk 20 and at the time of the recording/reproducing of the second optical disk 20' so as to deal with a trend toward higher NA.  The second light source 12 of a semiconductor laser is brought near to a coupling lens 13 without changing the position of the coupling lens 13 at the time of the recording/reproducing of the first optical disk 20 and at the time of the recording/reproducing of the second optical disk 20'.

Title: Joining method by resistance heat
Inventor: MATSUDA YASUO
IPC: B23K11/00
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To improve welding quality by surely joining to the inside center of a joining part even in the case of a solid member to be joined. SOLUTION: In a state where an insert metal 3 is interposed between the first and second members 1, 2 to be joined, with the two members 1, 2 held between a pair of electrodes 4, 4, an electric current is flowed between the electrodes 4, 4, thereby melting the insert metal 3 by resistance heat, and joining the first and second members 1, 2. This insert metal 3 consists of a thick center part 31 and a thin circumferential part 32 which is formed integrally on the outer circumference of the thick center part 31; in the initial stage of energization, only the thick part 31 comes into contact with each of the first and second members 1, 2. Since the electric current flows first to the thick center part 31 and heats it preferentially, the joining part is surely joined to the inside center, ensuring the welding quality.

Filed: 1985-10-31
Abstract: PURPOSE:To widen the installation range of extension telephone sets capable of answering by providing a calling means for extensions with a setting means which selects and sets extensions connected to trunk lines previously by the trunk lines and a means which sends out a call signal to said plural set extensions corresponding to terminating trunk lines. CONSTITUTION:A figure shows that there is an incoming call to one trunk line for extension telephone sets TEL0-TEL5 and to two trunk lines for TELs 0A-2A. Solid lines, broken lines, and dashes lines having arrows show routes of indicate connections after answering, signal transmission and audible tone transmission respectively. When there is an incoming signal to a trunk line, a call signal is sent out to TEL. A signal tone at this time is different from that of a general incoming call. One of plural TELs which are called at the same time is installed at a different place from the group and extension telephone set is set. The trunk line is connected to the TEL which answers first among plural TELs to which the call signal is sent out at the same time and call signals of other TELs are stopped, thus making a connection.

Filed: 1984-11-20
Abstract: PURPOSE:To simplify structure, to minimize the influence of backlash, and to improve measurement precision and resolution by converting the rotation of a contact wheel into the rotation of a shaft perpendicular to said wheel and providing numbers of magnetic bodies at the outer periphery of the shaft. CONSTITUTION:A bevel gear 6 fixed coaxially with the contact wheel 1 which profiles a necessary route on a drawing such as a map and another bevel gear 7 engaging said gear are used in combination to convert the rotation of the contact wheel 1 into the rotation of the shaft 8 perpendicular to the contact wheel 1. Many magnetic bodies 9 are provided at axially different positions of the outer periphery of the shaft 8 where the radial phase shifts by, for example, 40 deg., and magnetic sensors 10 corresponding to the magnetic bodies 9 are arranged closely along the shaft 8, thereby counting an AND result among outputs of the respective sensors 10. The resolution is determined by the diameter of the shaft 8 and the phase pitch of the magnetic bodies 9, but the pitch is selected relatively freely by varying the length of the shaft properly, so an encoder is increased in resolution greatly which the size except the length is held constant.

Abstract: PURPOSE:To extend a position detection range to control the position of a magnetic head in the wide range by reducing the capacity of a capacitor of a parallel resonance type detector at the time of special reproducing. CONSTITUTION:At the time of special reproducing, a switching circuit 16 is connected to first capacitors 13a and 13b and the capacity of a capacitor of a bridge circuit is reduced to make the resonance frequency of the bridge circuit higher than the frequency of a current supplied to a detecting coil and a smooth front slope characteristic is obtained.

The control circuit 20 supplies a control voltage corresponding to the extent of movement of a magnetic head 1, which is preliminarily determined for each mode, to a bimorph element 2 through a slip ring 5 to move the magnetic head 1. Thus, the position detection range is extended to control the position of the magnetic head in the wide range.
