Title: Convexed plane acoustic converter
Inventor: FUJIMOTO EISUKE
IPC: H04R7/12
Filed: 1981-05-11
Abstract: PURPOSE:To improve the split oscillation excellent in the directivity over a broad band, by using a vibration diaphragm in which the back side is taken as almost flat construction and the front side is as convexed construction. CONSTITUTION:The back side of a vibration diaphragm 1 is formed as almost flat construction 10 and the front side is as convexed construction 11, and a coil bobbin 2 is bonded at the back side of the flat construction 10. The convexed construction 11 at the front side is formed with a foamed material and the surface is enclosed with a hard material. A light weight member 12 can be filled between the convexed construction 11 and the flat construction 10. From the execution of this invention, since sound waves radiated from the convexed plane at the surface of the diaphragm are spherical waves as shown in the figure, the directivity can remarkably be improved in comparison with conventional construction. Since the cross section of the diaphragm near a voice coil having greater amplitude can be increased, the split oscillation can be suppressed and the distortion of the diaphragm can be prevented.

Title: Optical communication system
Inventor: ASHIKAWA SHIGEAKI
IPC: H04B10/079
Filed: 1991-04-04
Abstract: PURPOSE:To prevent a fault due to an alarm without causing a device alarm even when a main signal is interrupted while the main signal is switched to an AIS system by providing a function detecting momentary interrupt due to the changeover to the AIS system in an optical repeater. CONSTITUTION:When an optical signal with a lower level than a specified level is inputted from a host side transmission line 10a, an optical reception section 1 outputs an optical input interrupt alarm. Moreover, when an erroneous signal is inputted, a coding section 2 outputs a synchronization interrupt alarm. The alarms are ORed by an OR gate section 6 and held by a delay reset section 7 for a time required for changeover. On the other hand, when an alarm signal AIS is inputted from a main signal side, a detection section 5 detects it to close a gate 8 and to inhibit an output of a device alarm 10 from a delay section 7. Thus, the occurrence of a fault due to production of the device alarm is prevented by inhibiting the output of the device alarm for a time when the transmission output is switched to the AIS system due to line interruption in this way.

Abstract: PURPOSE:To remove the effect of the deflection of a torsion bar, by supporting two cylinders which are moved in conjunction with two shaft linked with the torsion bar with bearings which are coupled and fixed in a case so that the magnetic coupling state of the cylinders is changed by relative rotations. CONSTITUTION:A shaft 1a which is attached to a steering wheel and a shaft 21c which is attached to a steering mechanism are coaxially linked with a torsion bar 21b and inserted into a tubular case CA. Magnetic cylinders 27, 28 and 29 are supported with bearings 23 and 24 which are coupled and fixed in the case CA through nonmagnetic cylinders 25 and 26. The shafts 21a and 21b and the cylinders 25 and 26 are associatively rotated through pins 22 and 22. A gap between the magnetic cylinders 28 and 29 having asymmetric end surfaces with respect to the axis is changed by the relative rotations of the cylinders 25 and 26. The gap is detected with a coil 33 which is wound around a magnetic tube 31. Thus, torque between the shafts 21a and 21c is computed. Since the cylinders 27-29 are supported with the bearings 23 and 24, there is no effect of deflection of the torsion bar 21b. A coil 32 is used for temperature compensation.
