Title: Vortex flowmeter
Inventor: YOSHIOKA KENICHI
IPC: G01C9/06
Filed: 1989-02-13
Abstract: PURPOSE:To make it possible to generate a flow-rate signal smoothly from a zero flow rate to a large flow-rate region by automatically switching a vortex flow rate sign based on the first vortex frequency to a lower frequency when the vortex signal frequency becomes a frequency which is slightly larger than a suddenly disappearing frequency. CONSTITUTION:A voltage/frequency converter circuit 40 converts an inputted vortex signal SV into a low vortex frequency signal f2 and outputs it into a switching circuit 41. A frequency/voltage converting circuit 42 converts a vortex flow rate signal f2 into a voltage which is proportional to the signal and outputs it into a comparing circuit 43. The output of the circuit 42 is applied to one end of the input terminal of the circuit 43. A reference voltage Er corresponding to a vortex frequency which is slightly larger than a vortex fre quency at the limit where a vortex is not generated from a reference power source 44 is applied to the other end. The opening and closing of a switch 45 is controlled by the voltage at the output terminal. The signal f1 is applied to one end of the switching terminals of the switch 45, and the signal f2 is applied to the other end. The signal which is selected with the switch 45 is outputted to an output circuit 32 from the common end. When the signal f1 approaches the vortex frequency and the corresponding output of the circuit 42 becomes smaller than the voltage Er, the output level of the circuit 43 is inverted, and the switch 45 is switched to the frequency f2.

Title: Alkali-proof glass composition
Inventor: YAMAMOTO KATSUSABUROU
IPC: C04B14/42
Filed: 1982-03-03
Abstract: PURPOSE:To obtain the titled glass composition having a high ZrO2 content, convertible into a fiber, and showing superior alkali resistance, by providing a special composition consisting of SiO2, ZrO2, Na2O, B2O3 and Fe2O3. CONSTITUTION:A batch prepared by blending, by weight, 54.0-60.0% SiO2 with 23.5-25.0% ZrO2, 17.5-19.0% Na2O, 2.0-4.0% B2O3 and 0.2-1.0% Fe2O3 is melted and refined to obtain an alkali-proof glass composition. The meltability of the composition is improved by utilizing the synergistic effect of Na2O2 and B2O3 without using fluoride which erodes refractories and rare earth metallic oxide which makes the cost of starting materials higher. By adding the adequate amount of Fe2O3, the rate of heat radiation of the glass is increased to facilitate conversion into a fiber without increasing the liq. phase temp. Accordingly, the composition can be melted and converted into a fiber at an industrially advantageous temp.

Title: Method for ashing resist
Inventor: OBUCHI KAZUTO
IPC: G03F7/42
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To accurately find the changeover timing of ashing conditions of a resist film after ion implantation. SOLUTION: When plasma is generated in a chamber, the concentration of oxygen radicals increases suddenly as shown by T1. Since oxygen radicals do not contribute toward ashing an altered hardened layer, the concentration of oxygen radicals is kept high up to T2. When the ashing of the altered hardened layer approaches the end point, a bulk part is exposed, oxygen radicals are consumed in ashing the bulk part and the concentration of oxygen radicals lowers slowly from T2 to T3. While the ashing of the bulk part is carried out, the concentration of oxygen radicals is kept low because oxygen radicals are consumed. In accordance with the decrease of the amount of the bulk part that consumes oxygen radicals, the concentration of oxygen radicals increases slowly.

IPC: F28F1/12
Filed: 1981-03-10
Abstract: PURPOSE:To make it possible to manufacture easily even an elongated heat transfer pipe attached with coiled fins by a method wherein a chain-like coiled fin unit is arranged around the heat transfer pipe in such a manner that a straight linear member is passed through the overlapped ends of the coiled fin unit. CONSTITUTION:The prefabricated coiled fin unit 13 is arranged about the heat transfer pipe 11 and is pressed against the pipe by applying a couple of forces in the direction of the arrows A as if to enbrace the pipe by use of a jig A comprised of a couple of opposing members 14. In this case, each of the coiled fine 12 expands to some degree so that both ends of the coiled fin unit 13 are overlapped each other as at 12' and 12'. Therefore, in the case of the instant invention, the straight linear member 16 is passed through the overlapped section of the coiled fins 12' when the unit 13 is arranged about the heat transfer pipe 11. As a consequence, all of the coiled fins 12 are brought into resilient contact with the outer periphery of the pipe 11. Further, it shouled be noted in this connection that the insertion of the linear member 16 into the overlapped section of the coiled fins 12' can be performed in a mechanical method. The linear material 16 thus inserted is then bent so as not to slip out of the fins 12' and is silver- brazed to the fins to thereby increase the strength of attachment thereof to the fins.
