Title: Manufacture of damper for speaker
Inventor: SATO HITOSHI
IPC: H04R9/02
Filed: 1989-08-24
Abstract: PURPOSE:To prevent fiber from being damaged in the application of hot forming press, to improve the linearity of force-displacement characteristic of a damper, and to prevent higher harmonic distortion occurring in the low frequency area of a speaker by impregnating thermosetting resin and a mold releasing agent in a base material of cotton or aromatic polyamide, and performing the hot forming press after applying tack dry. CONSTITUTION:Firstly, phosphoric ester of around 3wt.% is impregnated in the base material of cotton or aromatic polyamide, and it is dried at around 1000 deg.C. Next, phenol group thermosetting resin of around 10-30wt.% is impregnated in the base material, and is dried in atmosphere of 130-150 deg.C. The damper 21 is comprised by applying the hot forming press >=200 deg.C on the material. By employing such manufacturing, superior linearity in the force-displacement characteristic of the damper can be obtained since no reduction of the elastic modulus of damper fiber occurs, and satisfactory rolling strength can be obtained, and productivity can be improved.

Filed: 1983-11-19
Abstract: PURPOSE:To load automatically and continuously many magazines and to obtain an apparatus utilizing the spaces efficiently by providing a magazine pusher which pushes the magazines at the lower stages in conjunction with the magazine lifter to the lower side thereof. CONSTITUTION:When a lead frame passes on a lower feed roller 17a at the lower side, a sensor detects it and operates a lift cylinder 25. The lead frame is pressed between an upper feed roller 17b and the lower feed roller 17a and is then sent to the magazine by the lower feed roller 17a. In this case, since inclined side 19a of pusher is pressed by a holding roll 24 and the pusher 19 as a whole is sunk under the surface of a chute 23, the lead frame passes thereon, the rear end goes out of the roller 17 and the front end reaches the roller 18. The sensor provided in the vicinity of feed roller 18 works in order to operate a lift cylinder 26. Moreover, the upper feed roller 18b is moved downward, holding the lead frame together with the lower feed roller 18a.

Title: Elevator
Inventor: KOTANI KENICHIRO
IPC: B66B7/02
Filed: 1989-08-28
Abstract: PURPOSE:To reduce vibration energy in a such a condition that usual guides which are oppositely attached to an elevator body are attached without using special attaching fixture, by laying parallel guide rails with their joints being shifted from each other so that both guides avoid passing simultaneously over the joints. CONSTITUTION:First and second guide rails 4, 5 are laid in parallel with each other with their joints 4a', 5a' being shifted from each other by a predetermined distance. With this arrangement, even with the use of conventional guides 7 attached to an elevator body 5, the guides 7 avoid passing simultaneously over the joints 4a', 5a'. Accordingly, vibration generated at the joints 4a' do not superpose with vibration generated at the joints 5a'. Accordingly, the superposes vibration is never transmitted to an accommodation room, and accordingly, uncomfortable noise which has bean inherent to conventional elevators, is not caused. With this arrangement, the occurrence of comfortable noise can be eliminated only by shifting the joints 4a', 5a' of the guide rails 4, 5 from each other by a predetermined distance.

Abstract: PURPOSE:To enable stable pulse wave synchronization MR photography by arranging a light source to supply optically light-to a detecting section disposed outside a predetermined magnetic field and a photoelectric converter to receive optically an optical pulse wave signal outputted by the detecting section and convert it to an electric signal. CONSTITUTION:A detector 10 has a detecting part 11 provided with a luminescent end 1, light receiving end 2, etc., a light source unit 13 for supplying light S1 thorough an optical fiber cable 12 to the luminescent end 1 and a photoelectric converter 15 for receiving an optical pulse wave signal S2 received by the light receiving end 2 through an optical fiber cable 14 to convert the signal to an electric signal S3. The light source unit 13 and photoelectric converter 15 are disposed outside a predetermined magnetic field formed in the MR photography of an MRI system. Thus, since the light S1 supplied to the detecting section 11 and the optical pulse wave signal S2 outputted by the detecting section 11 are optically transmitted by the optical fiber cables 12, 14, induction noises are not generated even if the optical fiber cables 12, 14 are disposed in the predetermined magnetic field formed in the MR photography, so that the stable pulse wave synchronization MR photography can be performed.

Title: Magnetic recording and reproducing device
Inventor: YOKOYAMA MASATO
IPC: G11B15/61
Filed: 1994-09-13
Abstract: PURPOSE: To stably run a magnetic tape by rotating a rotary roller keeping in contact with a part of the magnetic tape to be in helical contact with a drum and inclining its axial line to the traveling direction of the magnetic tape. CONSTITUTION: Since pressing force F is acted upon the magnetic tape A in contact with the rotary roller C by their surfaces, the magnetic tape A is hardly damaged as compared with the case of directly pressing a tape edge. In this case, the optimum pressing force F for stably traveling the magnetic tape A along a tape lead G can simply be obtained by changing a friction coefft. between the magnetic tape A and the rotary roller C, changing contact force of the rotary roller C against the magnetic tape A and changing the number of rotary rollers C to be installed. Therefore, the magnetic tape can stably be run without requiring high accuracy for fitting tape guides and the drum, etc.
