Title: Wavelength multiplex coherent optical transmission system
Inventor: SUZUKI KAZUNOBU
IPC: H04B10/40
Filed: 1989-03-27
Abstract: PURPOSE:To miniaturize an amplification medium and to extend the transmission distance and capacity by inserting an optical amplifier made of a single mode optical fiber added with the rare-earth element Er excited by an output light of a semiconductor laser. CONSTITUTION:The output light of frequency stabilizing light sources 11a-17a becomes a wavelength multiplex signal light while being coupled through one optical fiber via optical modulators 21a-27a and a multiplexer 30a. Then the signal light is sent to a receiver side by a transmission optical fiber 31 and made incident into an Er added optical fiber amplifier 34 via a multiplexer 36. Then an output light of an Er fiber amplifier exciting light source 35 using a semiconductor laser having an oscillated wavelength in a range of 1.40-1.50mum is coupled via the multiplexer 36 and the light is stimulated and the amplifier 34 applies amplification operation. Then the amplified signal is inputted to coherent demodulation circuits 81a-87a via a demultiplexer 37a and photodetectors 71a-77a or the like and demodulated into an electric signal. Thus, the signals subject to wavelength multiplex are amplified in the lump, the transmission distance and the transmission capacity are expanded and the amplification medium is made small.

Title: Loopback test method
Inventor: NISHI KIYOTAKA
IPC: H04L69/40
Filed: 1986-04-02
Abstract: PURPOSE:To apply loopback test entirely independently of a terminal equipment by allowing a channel used for an opposite equipment to be tested to designate an equiment except the opposed equipment to apply loopback test. CONSTITUTION:A channel applying a loopback test of a bit multiplexer 3 does not send a reception signal to a terminal equipment 5 because the equipment number is an opposite station. In forming a loopback route 505 to a multiplex/ separation section 15, a data on an SYSX, CH1 is transferred onto a time slot of the SYSX, CH1, of a transmission time slot 504. The signal is sent to a reception time slot 502 of the bit multiplexer 1 and received by a time slot of the SYS1, CH1, but since the designated equipment number differs, the signal is not sent to the terminal equipment 4. Since the time slot 502 of the multiplex/separation section 14 in the CH 1 is detected as a signal when the signal is sent from the CH 1 of the time slot 501, the loopback test is executed entirely independently of the terminal equipment.

Title: Transfer mode setting system
Inventor: INOUE SUSUMU
IPC: H04L29/06
Filed: 1992-02-26
Abstract: PURPOSE:To set a transmission mode automatically by sending a transfer mode initializing signal from a transmission side to a reception side, initializing the transfer mode on the transmission side and the reception side so as to make the modes coincident with each other, and thereby setting the transfer mode. CONSTITUTION:The transfer mode initializing signal 5 is sent to the input output device 2 of the reception side from a computer 1 at the transmission side. Upon the receipt of the signal 5, the reception side initializes the transfer mode and sends a completion code 4 to the transmission side when the initializing is finished. Then the combination 3 of transfer mode setting characters to set the content of the transfer mode corresponding to the transfer mode is sent from the transmission side, the reception side decodes it to set the transfer mode. Thus, it is not required to make the transfer modes of the transmission side and the reception side coincident with each other, thereby setting the transfer mode automatically. Furthermore, even when the transfer mode is revised by ON/OFF of a power supply on the transmission side and the reception side, etc., in the course of the transfer, the transfer mode is set again automatically.

Abstract: PURPOSE:To form a coating layer uniform in thickness with a simple structure by providing a means for coating a flexible substrate with a coating material and a rotary guide member to support the substrate and reducing the diameters of both ends of the member in the axial direction toward both ends. CONSTITUTION:An uncoated base film 6A is guided by a couple of guide rollers 8A and 8B and traveled along the front blade face 4 and smoothing plate face 5 of a die 1. A magnetic coating material forced into the pocket 2 of the die 1 is discharged from a slit 3 to form a coated base film 6B. In this case, the guide rollers 8A are shaped so that the diameters of both ends 8b are made smaller than the diameters of the coating parts 8a for supporting and guiding the coating widths of the base films 6A and 6B. Namely, the rollers are tapered toward both ends 8b from the coating parts 8a. Consequently, both ends 6b of the base films 6 are deformed along the taper to release the impingement of the die 1, and the thickness of the coating film is uniformized.

Title: Press working method of press machine and pressing pressure increasing device of press machine used for this
Inventor: TSUTSUI YOSHIMITSU
IPC: B30B15/16
Filed: 1979-06-14
Abstract: PURPOSE: To make possible pressing beyond the maximum capacity of the press machine by increasing the pressing pressure of its ram by a force doubler, pushing down a movable working frame by this force and pressing the work.  
     CONSTITUTION: A pressing pressure increasing device 23 is placed on the bed 25 of a press machine 24 and a stationary working table 3 is fixed to the bed by means of a clamper 26. The work 27 is placed on the stationary working table and the press machine is operated. Every time when the ram 28 of the press makes one reciprocation, a movable working frame 5 makes one reciprocation by way of a hydraulic pressure doubler 10 and at the descending of the ram, it pushes down a plunger 13. Because of this, the plunger goes into a hydraulic fluid chamber 15 and a piston 12 is forced down by as much as the volume portion that it entered. Since the piston has a sectional area ratio of 5:1 with respect to the plunger, its descending is 1/5 time and the pressing pressure becomes five times. Namely, the movable working frame presses the work under pressure 5 times the maximum pressure of the ram.
