IPC: G01J5/58
Filed: 1990-06-12
Abstract: PURPOSE:To improve an S/N ratio remarkably and to enhance resolution by performing signal processings in two stages. CONSTITUTION:A transfer characteristic H'(z) =d R(z)'/T'(z) is computed based on (z) conversion T'(z) of a known temperature-distribution-signal series ad (z) conversion R'(z) of a temperature-distribution-signal series which is observed at this time. A deterioration-characteristic signal h(p) which is obtained by inverse (z) conversion is held in a memory. When the region wherein the temperature distribution must be found and the conditions of temperature profiles are specified, the estimated solution of the true temperature-signal series which is to become the best approximated value is obtained by a nonlinear least-square method among the sets of the signal series satisfying the temperature profiles in the specified region by suing the deterioration characteristics obtained in the first stage.

Title: Apparatus for vaporizing volatile material
Inventor: YOKOGAWA TOSHIYA
IPC: H01L21/205
Filed: 1986-06-27
Abstract: PURPOSE:To control the amount of vaporization of a volatile material accurately, by providing obstacles to the bubbles of a carrier gas, which passes through the volatile material, in a container for accommodating the volatile material. CONSTITUTION:Several sheets of flat plates 7 made of the same material (SUS316) of a container 3 are protruded in said container. The container is divided into several chambers. The neighboring chambers are connected at the end parts of the flat plates 7. The connecting parts are alternately arranged so that the bubbles of a carrier gas pass through a volatile material in a snaking state. Thus the contact area of the volatile material 2 and the container 3 becomes large. The bubbles go up to the surface of liquid in the volatile material 2 in the snaking state. Therefore, the bubbling path becomes long. The staying time of the bubbles in the volatile material 2 becomes long. Therefore, the volatile material 2 becomes very homogeneous, and the accurate temperature keeping state is maintained.

IPC: B23K20/08
Filed: 1981-09-29
Abstract: PURPOSE:To prevent fine cracking of a press-welded part of a pipe and a porous pipe plate which have been press-welded already, by installing a metallic plug device to the inside of a pipe which has been press-welded by explosion already, and after that, press-welding the pipe to its adjacent pipe plate hole by explosion. CONSTITUTION:When a split cotter pin 9 is inserted into the inside surface of a pipe 3 which has been press-welded into a hole 1 already by explosion, its expanded head part hits against a stepped part of a press-welded part and a non-press-welded part of the pipe 3, and stops. Subsequently, when a tape plug  10 is driven in from the upper part of the center hole of the split cottor pin 9,  since the split cotter pin 9 has a slit 12, it is gradually expand-opened by the tapered part of the plug 10, and is pressed so that the boundary between the  press-welded part and the non-press-welded part is not opened, in a push origin  part 11. It is fixed in this way, and after that, when a pipe 4 is press-welded into a hole 2 by explosion, fine cracking in the press-welded part of the pipe 3 and  a porous pipe plate 5, due to tensile stress is not generated at all. Also, even when a plug is used instead of a pipe, the same result is obtained.

Abstract: PURPOSE:To widen the dynamic renge of the whole device by providing a photometric part with a means which distributes plural pieces of luminous flux and a detecting means which convert the respective pieces of luminous flux photoelectrically, and comparing said detection output with a specific value and making a selection by an output part. CONSTITUTION:Fine luminous flux transmitted through an image medium is demultiplexed input two by an optical distributer and inputted to a high sensitivity and a low sensitivity photodetection system, whose output signals VA and VB are inputted to a signal mixing circuit 3 and converted by frequency converters 22 and 23 into signals proportional to logVA and logVB. The output logVB is compared with a threshold signal VT by a comparator 25. Here, the signal VT corresponds to the logarithmic value logTj of T1 in a figure A (showing the dynamic range of input signals V1 and V2 of the circuit 3). The output logVA, on the other hand, is added by an adder 25 to a detection system gain ratio signal VR. The signal VR is set on the basis of the ratio of VA and VB at the overlap part of dynamic ranges of two detection systems. Then, MPX26 selects its input according to the output S of the comparator 26.
