Title: Magnetic head support mechanism of flexible disk drive
Inventor: WAKABAYASHI MANABU
IPC: G11B21/20
Filed: 1985-06-14
Abstract: PURPOSE:To reduce an off track due to an inclination of a head and fully maintain a signal level and a reliability by effectively lowering a contact surface of a disk and a slider height of a rotating center of the magnetic head. CONSTITUTION:A magnetic head 1 is composed of sliders 2, 3 fixed to a magnetic core 4, a gimbal 10 fixed on an upper surface of the slider 2, a coil 6 wound on the magnetic core 4 and a back core 7 fixed to an end section of the magnetic core 4 and a peripheral section of the gimbal 10 is fixed to a carriage 9. A support section 8 extending from the carriage 9 passes through a through hole 11 of the gimbal 10, reaches to a bottom section of an accommodating section 5 and supports a center of rotation O of the magnetic head 1. An equivalent height of the slider 2 is a distance L from a contact surface 16 of a disk to the center of rotation O and can be drastically reduced.

Title: Rear focus type zoom lens
Inventor: TOCHIGI NOBUYUKI
IPC: G02B13/18
Filed: 1993-04-30
Abstract: PURPOSE:To miniaturize the whole lens system, to make the photo-graphying viewing angle of a wide-angle end a wide angle and to obtain a large variable power ratio by moving four lens groups, performing power variation and focusing and specifying the ratio of the focal lengths of a third group and a fourth group. CONSTITUTION:At the time of varying a power from a wide-angle end to a telescopic end, a second group L2 is monotonously moved to the side of an image plane, a diaphragm SP and a third group L3 are integrally moved to the object side so as to have a projected locus and a fourth group L4 is moved to the object side so as to have a projected locus independently of each other. By representing thefocal length of an ith group by Fi, the zoom lens is composed so as to satisfy the condition shown by 2.5<F3/F4. This condition is related to the ratio of the focal lengths F3, F4 of the third and the fourth groups L3, L4 and is useful for making a back-focus sufficiently long and maintaining good optical characteristic while attainig the compact system from a diaphragm SP on.

Title: Fadeout device
Inventor: KATSUNUMA TETSUO
IPC: H03G3/00
Filed: 1989-05-22
Abstract: PURPOSE:To make a fadeout end time constant by outputting a control signal so as to decrease the sound volume and sitting an output start time of the control signal so that the sound volume is zero at the fadeout end time. CONSTITUTION:A detection means 101 detects the sound volume level of a sound adjustment device 100 and supplies the level to a control means 102. The control means 102 in response to the sound volume level sets an output start time of the control signal so that the sound volume level is zero at a set fadeout time. When the control signal is outputted to the output start time at the set output start time, the sound volume adjustment device 100 reduces the sound volume level accordingly. Thus, the time of the end of fadeout is made nearly constant.

Title: Node address setting system
Inventor: NAKAMURA MASARU
IPC: H04L12/42
Filed: 1981-08-17
Abstract: PURPOSE:To automatically set node addresses without relying on man power, by installing an area, into which a specified pattern is inserted, in the frame format of monitoring signals transmitted from a monitor station. CONSTITUTION:Specified pattern inserting areas E and R are installed in areas which are exclusively used for SV in a frame format. When a node address is assigned, an SV (a) sends an E-flag E and an address area ADD to an ND (b) by setting them to ''1'' and ''1'' respectively. The ND (b) detects the ''1'' of the E-flag E and discriminates that a node address is to be registered. Then, the ND (b) registers the ''1'' of the content of the address area ADD as the address of own station and sends the content of the ADD to the next ND (c) after ''1'' is added to the content. The ND (c) registers the 2 of the content of the ADD as the address of own station and sends the content to the next ND (c) after ''1'' is added to the content. Since the NDs existing after the SV (a) perform the same operation, the node address is set automatically, correctly, and in order.

Filed: 1989-05-22
Abstract: PURPOSE:To stop a traveling stage in place accurately by furnishing two press ing plates, which use the slide friction force of sliding members to stop that unstable rotating condition of a ball screw remaining when the driving current to a DC motor is shut off. CONSTITUTION:No.2 pressing plate 62 is installed with a certain gap reserved relative to No.1 pressing plate 61, and sliding members 71, 72 of fluoric resin are affixed to their inner surfaces, and these two places are coupled together resiliently using coil springs 81, 82 and a bolt 9.

Title: Brushless motor
Inventor: MOROTO KIYONORI
IPC: H02P6/08
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To improve motor efficiency by generating rotation torque effectively, in a 5-phase brushless motor. SOLUTION: When a motor is driven, currents are made to simultaneously flow in by three phases from among 5-phase armature coils A21-E21. In this case, currents are made to flow only in 3-phases armature coils (that is, 3-phase armature coils having a large percentage of contribution to generation of rotation torque) facing the boundary part of an N-pole and an S-pole of a magnet rotor 23. As compared with the case of 4-phase current flowing, rotational torque can be generated effectively, and motor efficiency can be improved. In this case, it is preferable that the number of poles of a stator 19 be set as 5×n, where (n) is a natural number, and the number of poles of the magnet rotor 23 is set as 4×n.  Thereby the boundary part of the N pole and the S pole of the magnet rotor 23 can be made to surely face the 3-phase armature coils which turn into the current flowing phases from among the 5-phase armature coils A21-E21.

According to such a leading edge shape, ununiformity of press-contact force to a rotary drum 2 by the blade member 1 is corrected, therefore, the press-contact force can be equalized. In this regard, as for the leading edge shape, not only the trapezoidal shape but also a curve shape which is capable of correcting the ununiformity of the press- contact force is available.
