IPC: H04B10/80
Filed: 1987-08-05
Abstract: PURPOSE:To suppress the system power supply voltage at a low level by using a conductive sheath for each optical fiber element of an optical submarine cable and at the same time insulating these fiber elements from each other so that each reproduction repeater unit can receive independently the power supply. CONSTITUTION:A center part 11 of an optical fiber element 1 is connected to an optical input terminal 4 and an optical output terminal 5 of each optical reproduction repeater 7 of an optical submarine repeater 3. At the same time, a current is supplied from a sheath 12 of the element 1 through a supplying line 6. The satisfactory insulation is secured between the sheaths 12 of elements 1 as well as between a metal tube 9 and the outside by means of an insulator 8. Thus the power is supplied to each unit 7 from both ends of an optical submarine cable through the conductive sheath 12 of the element 1. In such a constitution, the independent power supplying circuits are formed and the voltage can be kept at a low level even with a multi-repeating system. Then a unit 7 can be freely set regardless of the power supply of other units 7.

IPC: F16F9/32
Filed: 1989-07-27
Abstract: PURPOSE:To change the damping force in both expansion and compression strokes by providing the first through third variable orifices on the first bypass passage. CONSTITUTION:In the expansion stroke, the volume of a lower chamber (b) is shrunk, the volume of an upper chamber (a) is expanded, the fluid in the chamber (b) flows into an outside chamber (c) via a lower passage (e) according to this volume change, and it flows from there into the upper chamber (a) and a reservoir chamber (d). Damping forces are generated at the second damping valve (h) and the first through third variable orifices (r), (s) and (t) in the flowing passage of the fluid. The flows on the valve (h) side and orifices (r), (s) and (t) are changed in response to aperture changes of variable orifices (r), (s) and (t), and the range of the damping force is changed. When orifices (r), (s) and (t) are throttled, a high-damping force range is obtained, when they are opened, a low-damping force range is obtained. In the compression stroke, the fluid in the chamber (a) flows into the chamber (b) and chamber (d), damping forces are generated at the first damping valve (g) and orifices (r), (s) and (t) in the flowing passage, and the same phenomenon as the expansion stroke occurs.

Title: Sound reproducing device
Inventor: TSUJISHITA MASAHIRO
IPC: H04S1/00
Filed: 1993-08-05
Abstract: PURPOSE:To improve the normal positioning of an acoustic image by measuring the delay time of a test impulse at a listening position for each speaker and by compensating the delay time of each delay circuit based on the delay time of the test impulse. CONSTITUTION:The impulses sent from an impulse generating part 12 are sent in sequence to the speakers 19L and 19R via a switch 13 and then collected as sounds through a space by a microphone 20 set at a listening position. An arithmetic part 22 measures the delay time of space propagation for each speaker based on the time difference caused between the generation and collection of impulses and stores the data on these measured delay time. A control system 24 automatically gives a command to the part 12 for output of impulses and controls the delay time of delay circuits 15L and 15R for each channel based on the data on the delay time. Thus an acoustic image is formed at a prescribed position regardless of the difference of distances between the listening position and each speaker.

Title: Command transfer method
Inventor: ISHII TOSHIKI
IPC: H04L1/00
Filed: 1990-07-24
Abstract: PURPOSE:To reduce a rate of a transfer command being an important command considerably by adopting a command in common to an error check code for the important command to a slave system and not using commands different by prescribed bits from the important command. CONSTITUTION:A system stop command is a data having a 6-bit value of '010101' and 1's complement for high-order 3 bits is used for a level for low- order 3 bits. A command 'b' is a command different by one bit from the system stop command 1 and commands transferred in error as the system stop com mand different by one bit from the system stop command 1 are commands 'b'. Then the commands 'b' are not used as usual commands but remaining commands shown in space in table are used for usual commands. Thus, any command transferred in one bit error is not the system stop command and a rate causing a detrimental mistake due to erroneous command transfer is remarkably reduced.

Abstract: PURPOSE:To control generation of wrinkles, etc., on a part of reduced diameter at drawing work by forming a thin thickness part thinned gradually from a thick part of the bottom end of an open end part of a can shell towards the open end side except a flange formed part. CONSTITUTION:The ironing work is performed on the cylindrical can shell possessed of a bottom plate, on the open end part 3 thicker than the thickness T1 of the shell part 2, the thin thickness part 6 of which thickness T3 of the upper end part is thinner than the shell thickness T2 of the thick part 4 of its lower end part is formed excluding the flange forming part 5.
