IPC: G02B6/24
Filed: 1991-02-28
Abstract: PURPOSE:To improve characteristics such as gain, saturation output, noise index, etc., of the optical fiber amplifier. CONSTITUTION:An incidence-side lens 11 and a projection-side lens 12 are arranged on both left and right sides of an optical element 10 and an incidence port 13 and a projection port 14 for exciting light are arranged on the left side of the incidence-side lens 11 and the right side of the projection-side lens 12.

Title: Superconductive magnet
Inventor: SHIBUTA NOBUHIRO
IPC: H01F6/00
Filed: 1986-03-11
Abstract: PURPOSE:To prevent a cooling agent from flowing over or the evaporation amount of the cooling agent from remarkably increasing caused by the invasion heat of the cooling agent flowing into the port when a magnet is turned both vertically and horizontally, by making a port provided on a cryostat stand at an edge part in the manner that the slant angle with respect to the axial center is made to be approximately 45 deg.. CONSTITUTION:A port 3 provided on a cryostat is formed so that an inner pipe 3a continuing to an inner container 7 and an outer pipe 3b continuing to an outer container 9 are concentrically arranged with a heat insulating layer 8a continuing to a heat insulating layer 8 between the inner and outer containers, and is made to stand with an angle theta of approximately 45 deg. with respect to the horizontal plane at the edge part where a peripheral wall 2b of the cryostat is perpendicular to the other side wall 2a. Since a liquid surface of a cooling agent 10 is kept below the root terminal of the port 3 in both horizontal and vertical directions, the cooling agent does not flow out from the port. The liquid level of the cooling agent 10, permitting invasion of heat from outside, separates apart from the port, preventing the evaporation amount of the cooling agent from increasing.

Title: Soldering method for printed wiring board
Inventor: ZEN MITSUO
IPC: H05K3/34
Filed: 1988-03-11
Abstract: PURPOSE:To eliminate un-soldered sections and to improve reliability of soldering, by a method wherein after a primary soldering treatment is performed, a printed wiring board is changed in its direction, and subsequently the soldering surface of the printed wiring board is again treated with a secondary soldering treatment. CONSTITUTION:After a primary soldering treatment is performed, change of direction is performed in a printed wiring board so that chip components are directed in the direction different from that during the primary soldering treatment. At this time, in the case where the front and the back of the chip components are reversed, the direction of the printed wiring board is changed by 180 degrees. On the other hand, in the case where the chip components disposed perpendicular to the advance direction of the printed wiring board is only directed in the parallel direction therewith, the direction of the printed wiring board is changed by 90 degrees. After change of the direction is performed in such way, the printed wiring board is fed to a secondary soldering apparatus, and flux coating and preheating are performed in fluxers 2, 7 and preheaters 3, 8, respectively. In a high wave soldering vessel 11, the positions in the printed wiring board difficult for solder to deposite thereto are directed in the direction in which it is easy for solder to deposite thereto. Therefore, solder perfectly penetrates the un-soldered positions provided during the primary soldering treatment, so that there are no un-soldered positions in the printed wiring board.

Title: Picture recording and reproducing device
Inventor: OOYAMA MASAO
IPC: H04N9/82
Filed: 1983-03-31
Abstract: PURPOSE:To make a picture and an audio signal coincident with each other by recording a picture signal color change control signal to a prescribed position on an audio magnetic tape and reading this signal at reproduction so as to change display color of a reproduced picture of a color picture display device. CONSTITUTION:The 1st tape recorder 31a is selected to the reproducing mode and the 2nd tape recorder 31b is selected to the recording mode. Then, the user gives a color change control signal adding command to a color change control signal adding circuit 80 at a desired position while monitoring by a receiver 36 and a speaker 37. Thus, this circuit 80 adds the color change control signal to a digital data read from a memory 45 and outputs the result. The digital data has a delay for 4 picture elements' share by this addition, but the delay is cancelled by a silence part between lines because this is coincident with the count difference between a write counter 50 and a read address generating circuit 51. Thus, both signals are outputted to a tape recorder 31b.

Title: Testing device for integrated circuit
Inventor: TANAKA SADAAKI
IPC: G01R31/3181
Filed: 1980-04-28
Abstract: PURPOSE:To reduce the production cost of a test pattern, by varying optionaly the voltage level of an analog voltage signal to be supplied to an integrated circuit to be measured while generating the test pattern. CONSTITUTION:For the pattern storage part 11 of the pattern generating part, the lateral direction coincides with the bit direction with a bit constitution of bx, b0-b  and b +1-bm with the longitudinal direction coinciding with the word direction. The pattern data of bits bo-b  of part 11 is latched at the register 12 and by the contents of bit bx. Based on the information of latched b0-b , the converter DAC performs a D/A conversion. Then the voltage generator 13 including the converter DAC generates a voltage based on the contents of b0-b  to apply it to the analog voltage signal input terminal of the integrated circuit to be measured containing the ADC part inside. Thus the voltage level is varied for the signal which is applied according to the contents of the test pattern. As a result, a function test is possible by generating the test pattern only once, to reduce the test cost.
