Title: Optical repeater
Inventor: OKAWA YASUHITO
IPC: G02B6/293
Filed: 1987-04-09
Abstract: PURPOSE:To facilitate production and adjustment and to permit decrease of loss and reduction of cost by executing demultiplexing, branching and multiplexing by the constitution in which triangular prisms and trapezoidal prisms are used for glass blocks and half mirrors and band-pass filters are provided on joint surfaces. CONSTITUTION:The multiplexed signal inputted to a filter F1 is branched to two beams if said filter is constituted of the half mirror. One of the beams transmit the mirror and is guided to a filter F2 and the other is reflected therefrom and is guided to a filter F3. A wavelength lambda1 is guided to a convergent rod lens 6 and is converted to beam light which is obtd. in an output port P1 if the band-pass filter having such characteristics as to allow transmission of the wavelength lambda1 and to reflect a wave length lambda2 is used for the filter F2. On the other hand, the wavelength lambda2 is reflected by the mirror and is guided to the filter F4. The wavelength lambda2 is guided to a conver gent rod lens 7 and is converted to beam light which is obtd. in an output port P3 if the band-pass filter having such characteristics as to allow transmission of the wavelength lambda2 and to reflect the wavelength lambda1 is used for the filter F3. The wave length lambda1 is reflected by the mirror and is guided to the filter F4. The optical coupling loss is thereby decreased and the cost is reduced.

Title: Welding method between members
Inventor: OKAMOTO KENJIRO
IPC: H02K29/00
Filed: 1993-04-14
Abstract: PURPOSE:To maintain working accuracy such as perpendicularity between members to be welded at high accuracy. CONSTITUTION:Projection welding is taken as the welding method and a shaft 72 is welded and fixed to a tabular plate 70 so as to stand upright. In welding, a projection 34' is formed on the plate 70 side and an annular recessed groove 60' is formed on the welding surface corresponding to the position projection 34' on the shaft 72 side. When welding is performed, the projection 34' is abutted on the surface surrounded by the recessed groove 60', these members are pressed between fixed and movable electrodes and a DC current is supplied between the electrodes to perform welding. The projection 34' and the vicinity of the part on which this abuts are melted by the supply of the current and plate 70 and the shaft 72 are welded together. At this time, melt flows into the recessed groove 60' and is prevented from flowing out to the outside. As a result, the plate 70 and the shaft 72 can be welded and fixed together with high prpendicularity.

Filed: 1983-05-19
Abstract: PURPOSE:To expand larger-scale bag-shaped items such as rubber boats filled with compressed gas, etc. by jetting the compressed gas, etc. from an orifice and simultaneously filling the bag-shaped items with air. CONSTITUTION:A hollow pipe 2 that sends gas to a bag 6 is connected to the gas outlet (c) of a container 1 that houses compressed gas, etc. and an orifice 4 is installed halfway. In addition, a check valve (h) is provided at the inlet 7 of the bag 6. When the compressed gas, etc. in the container 1 is jetted, the compressed gas, etc. passes through the orifice hole (e) of the orifice 4. Consequently, the pressure in the environment is reduced and air is sucked from the hole (g) of an outer pipe (f). Accordingly, the compression gas, etc. changes into gas accompanied by air and the gas is sent in the bag 6. As a result, air can be simultaneously sent, using the energy of such as compressed gas, etc. and the larger- scale bag 6 can be expanded.
