Title: Torsional vibration damping mechanism
Inventor: JIERARUDO DAGURASU DEIMON
IPC: F16D13/64
Filed: 1988-08-20
Abstract: PURPOSE: To effectively reduce noise generated during idling and connection of a transmission by arranging at least a first and a second spring sets disposed in series, and arranging a damping mechanism operatively disposed in parallel with the both spring sets. CONSTITUTION: A torsional vibration damping mechanism 30 of a drive line comprises a first and a second spring sets 36, 38, a middle element 40, and a viscous damper 44. The first spring set 36 has a relatively high torsional constant, while the shaft 22 is connected to a load, the torsion is dampened by the pliability. On the other hand, the spring set 38 has a relatively low torsional constant, while the shaft 22 is not connected to a load, the torsion is dampened by the pliability. While the shaft 22 is connected to a load, the spring set 38 is under an unsaturated condition or generates an impliable reaction. The damping mechanism 44 is arranged in parallel to the spring sets 36, 38 disposed in series. Therefore, the bouncing back force of the two spring sets 36, 38 is attenuated or reduced.

Title: Lead-frame fixing apparatus
Inventor: HIOKI MUTSUO
IPC: H01L23/50
Filed: 1986-09-03
Abstract: PURPOSE:To prevent wire breakdown and the deviation of the pitch of a lead frame itself due to minute vibration at the time Of working, by attaching a magnetic plate to the inner surface of a jig. CONSTITUTION:A magnetic plate 8 is stuck to the inner surface of a rear plate 7. The entire tip part of each lead frame 4, which is inserted between grooves 2 and 2, is firmly attracted. Even if minute vibration is applied to a jig 1 at the time of working, the vibration is not transferred so violently as in a conventional apparatus. Therefore, the vibrating shock to a semiconductor chip on the lead frame or to wires is allevaited. Problems such as wire breakdown can be positively avoided. Even if the jig 1 is vibrated a little or slanted, the accommodating position of each lead frame is not deviated. Therefore, working at the later automatic drawing step can be performed smoothly.

Filed: 1986-09-03
Abstract: PURPOSE:To prevent wire breakdown in interconnection, by forming a second phosphorus glass film having the concentration of phosphorus, which is lower than that of a first phosphorus glass film, on the first phosphorus glass film. CONSTITUTION:On the surface of a semiconductor substrate 1, a first silicon oxide film 2, a first phosphorus glass film 3 and a second phosphorus glass film 31, whose concentration of phosphorus is lower than that of the first phosphorus glass film, are sequentially formed. An electrode hole 5 is formed in the three films by a photoetching method. The second phosphorus glass film 31 suitably alleviates adhesion with a photoresist film in a step, for forming the electrode hole 5, and a positive tapered part is formed. Therefore, the electrode hole 5 has a tapered shape, whose cross sectional area is gradually expanded toward the outlet from the bottom part of the electrode hole 5. Thereafter, a metal film 6 is formed on the electrode hole 5 and the selected place on the second phosphorus glass film 31 by an evaporating method. The opening part of the second phosphorus glass film 31 in the vicinity of the outlet of the electrode hole 5 has an obtuse angle. Therefore wire breakdown does not occur in the metal film 6.

IPC: H04R9/06
Filed: 1984-10-02
Abstract: PURPOSE:To maintain good sound, pressure frequency characteristic and to reduce its characteristic variation by setting an air hole between a front and a rear air rooms in a baffle board or in a speaker housing. CONSTITUTION:As an air hole 59 formed of a recessed part of a baffle board 51 and a recessed part of a speaker housing 58 is equivalent to a parallel impedance in an equivalent circuit, it forms a low-cut filter and secures high frequency antiresonance, and thus good speaker characteristics is maintained. In addition, the hole 59 can be so decided by a part configuration as to be placed enough far from a sound hole 63 of the board 51, and its position can also be maintained in a fixed distance from a voice coil lead 54 by the arrangement of a leader line exit groove. Thus, the disturbance in sound pressure frequency characteristic is reduced and so is the variance in high frequency antiresonance frequencies.

Title: Voice coil motor
Inventor: WADA KATSUTOSHI
IPC: H02K33/18
Filed: 1988-08-23
Abstract: PURPOSE:To miniaturize a motor and to reduce the leakage of flux by making the thickness in the direction of magnetization small with a back yoke stretched out in the permanent magnet direction keeping the cross section as before. CONSTITUTION:The cross section of a center yoke 2 and a back yoke 3 constituting a magnetic circuit 1 viewed from the direction of an arrowhead A is U-shaped. The cross section of the center yoke 2 viewed from the direction of an arrowhead B is hexagonal. Similarly, the cross section of the back yoke 3 is U-shaped. A permanent magnet 4 is fixed so that its direction of magnetization may be directed to the opposite direction of yokes 2 and 3 and the flux will flow through the magnetic circuit 1 in the direction of arrowheads. The flow of flux through the magnetic circuit 1 thereby returns from the stretched- out section on both sides, left and right, of the back yoke 3. As the back yoke 3 can reduce its cross section to about 1/3 without saturating magnetism, the thickness becomes thinner than before and a motor 7 as a whole is miniaturized.

Abstract: PROBLEM TO BE SOLVED: To provide a locking effect for a tapping screw screwed in the prepared hole of a soft work. SOLUTION: A drive part 10 is provided to have an engaging wall 12 with which a driver bit is engaged and a slope 13, with which the driver bit is not engaged during rotation on the loosening side of a screw. A plurality of outer peripherally radially protrusions 14 in a sawtooth shape in cross section are formed in the seat surface of a head part 2. Besides, since a plurality of thread undercut 23 are formed in the thread 20 of a leg part 3 at equal intervals in a peripheral direction, even when the tip of the driver bit is either a minus or a plus shape, use is practicable.  Further, in the shape of a head part, a shape wherein during loosening of a screw, the driver bit is not engaged is formed and since the shapes of a seat surface and the thread are a shape that during loosening, resistance is increased, by a synergistic effect produced by the shapes, a reliable locking effect is produced. Further, screwing torque is not influenced by using environment, such as a material of resin and temperature, and complete locking is practicable.
