Title: Non-circular bellows and blow molding thereof
Inventor: FUKUHARA NAONARI
IPC: F16L27/12
Filed: 1993-01-16
Abstract: PURPOSE:To relax the fluctuations of the wall thickness of the ridges of bellows in the peripheral direction thereof and to control the wall thickness of the ridges of the bellows by making the height of the ridges of an area large in curvature in the peripheral direction thereof less than that of the ridges of an area small in curvature. CONSTITUTION:The height of the ridges of an area large in curvature in the peripheral direction thereof is made less than that of the ridges of an area small in curvature. Or, the height of the ridges of an area remote from the center of a cross section is made less than that of the ridges of the area near to the center of the cross section. As a result, the height of ridges is made relatively low at the area where a parison comes into contact with the inner wall surface of a mold in the peripheral direction of the mold and, when the ridges of bellows are finally molded on the parison, wall thickness difference is relaxed. That is, the heights (h) of the ridges are set, for example, to 41mm at the center of a long side part 14, 34.4mm at the center of a short side part 15 and 26.2mm at the center of a corner part 16 so that the wall thickness of the ridges 12 become almost uniform over the entire periphery to be gently changed.

Abstract: PURPOSE:To separate the interference between codes and channels by adding a control signal for detecting transmission detection with different phase to orthogonal channels at the transmission side, transmitting the result and setting weight information of a compensation filter for transmission characteristic equalization at the reception side so as to correct automatically the transmission characteristic. CONSTITUTION:An equalizer 30 consists of equalizers 31, 32 for eliminating interruption between channels and codes respectively, the equalizer 31 is expressed by LPF33-36 having transmission characteristics Uomega, Uomega, Tomega and Tomega and subtractor circuits 37, 38 at the output side equivalently. On the other hand, the equalizer 32 is expressed by LPFs 39, 40 having transmission characteristic Eomega and Eomega for equalization to eliminate the interference between codes. Then interference between channels is eliminated by passing an output signal of adder circuits 26, 27 through the equalizer 31 and the interference between codes is eliminated by passing it through the equalizer 32 at the post-stage.

Abstract: PURPOSE: To reduce frictional resistance on the surface of an ejection path, make the ejection path hard to be choked and enable chips to be ejected smoothly by providing an exciting means for exciting the ejection path through which the chips pass together with a cutting fluid. CONSTITUTION: Ultra sonic wave 54 is generated from an ultra sonic oscillator 2 by operating an oscillating power supply unit 3. After the generated ultra sonic wave 54 is resonated by a born 1, the wall surface of a groove 11c is excited radially of a gun drill 11 through cutting fluid 52 flowing in the groove 11c of the gun drill 11. Thus, the frictional resistance in the groove 11c of the gun drill 11 is reduced substantially to smoothly eject chips 53 flowing in the groove 11c of the gum drill 11. Accordingly, a deep hole in a workpiece 51 can be efficiently accurately worked by the gun drill 11, while the workpiece 51 and gun drill 11 can be prevented from being damaged and broken down.

Abstract: PURPOSE:To easily form an ohmic contact to keep a substrate at the minimum potential by a method wherein a polycrystalline semiconductor with the constant of impurity diffusion much larger than that of a single crystal semiconductor is used in the element isolation due to a dielectric. CONSTITUTION:Isolation grooves are provided after growing an N<-> epitaxial layer 3 and an Si nitride film 7 on the substrate 1 having a buried collector 2. Next, after forming a channel stopper 4 and an Si oxide film 6 in these grooves, an Si nitride film 7 is grown over the entire surface. Successively, after removing the nitride film 7 and the oxide film 6 of the region B of leading out the minimum potential, the grooves are filled by growing non-added polycrystalline Si 8 over the entire surface. Then, after removing the Si 8 except for a in the grooves, B is diffused into the Si 8 in the groove part, and accordingly an Si oxide film 6 is formed on the surface thereof. This B diffusion reaches easily the substrate 1 because of being performed through the polycrystalline Si, and therefore the region B ohmic-contacts on the substrate 1.
