Title: Manufacture of fiber fusion splicing type optical directional coupler
Inventor: KASHIWAZAKI AKIRA
IPC: G02B6/287
Filed: 1990-08-13
Abstract: PURPOSE:To easily manufacture the coupler which has an intermediate core layer by vapor-depositing a high-refractive-index layer on the outer periphery of a clad and coupling it with another optical fiber by employing a normal fusion splicing and drawing process. CONSTITUTION:The optical fiber in normal structure which has the periphery of the core covered with the clad 3 is prepared and a material which has a higher refractive index than the clad 3 is vapor-deposited on the entire outer peripheral surface of the clad 3 to specific length to form the high-refractive- index layer 4. Two optical fibers 1 which have high-refractive-index layers 4 are prepared and are brought into contact with each other to a specific distance and their specific parts are heated to unite both the optical fibers 1 and 1 by fusion splicing. Then heat diffusion is caused by the heating and their clads 3 and 3 are doped with titanium constituting the high-refractive-index layers 4 at the outer peripheries of the two fusion spicing optical fibers 1 and 1 are heated to draw the fibers. Consequently, the coupler which has the intermediate core layer 5 between the cores 2 and 2 is easily manufactured.

IPC: B23G5/20
Filed: 1989-08-22
Abstract: PURPOSE: To substantially manufacture core holes of different diameters in a tool by an end face cutting edge by making the outside diameter of the end face cutting edge the same as the core-diameter of a milling tooth or larger than the core-diameter, reducing the number of milling teeth than the number of threads and simultaneously forming the core holes and threads. CONSTITUTION: Thread-milling teeth 4 limit each one groove 5 between the teeth 4, a thread milling cutting edge 6 is formed, a thread-milling tool transfers to a tip part 7 toward the front and the tip part 7 has an end face cutting edge 8. This cutting edge 8 extends within a plane at a right angle to an axial line and transfers to a peripheral surface cutting edge working together in the same way when a core hole is generated at the rear of an acute angle bent part on the peripheral surface. Because all of the thread-milling teeth 4 arranged in a row have the same size and only the leading teeth perform cutting works, the remaining teeth work only for a guiding. Next, when the front teeth wear, the teeth are ground and removed, and subsequently the succeeding teeth in the row perform the cutting works.

Abstract: PROBLEM TO BE SOLVED: To prevent inhibition of circulation of the liquid refrigerant caused by the gasified refrigerant by cooling and re-liquefying the gasified refrigerant with a condenser interposed between a bearing and a sealing provided on both sides thereof. SOLUTION: Condensers 32 for leading a cooling fluid from outside are provided in each space defined by a bearing 12 and a seal ring 22 disposed on both sides thereof. This condenser 32 may be provided such that it cools a peripheral portion constituting the space, for example, the surface of a casing 26.

Abstract: PURPOSE:To increase the frequency of a rate pulse without exerting effect on the interpolation of B-mode data, by setting the writing time of the B-mode data to a frame memory so as to make the same longer than the cycle of the rate pulse. CONSTITUTION:The echo signal obtained from an examinee is received by the same probe 1 and applied to an adder 6.

An A/D converter 9 converts the inputted echo signal and a Doppler spectrum signal to digital signals to temporarily write the same in a line buffer memory 10 and the data thereof is read from a separate line memory to be written in a frame memory 11. At this time, the writing time is set so as to be longer than the cycle of a rate pulse PRF. By this method, the number of the interpolation data of a B-mode written in the frame memory 11 are increased. Therefore, the max. detection frequency of a Doppler mode can be raised without deteriorating the image quality of a B-mode image and a region where blood flow velocity is faster can be measured.
