Title: X-ray exposing device
Inventor: SAITO YASUNAO
IPC: G03F7/20
Filed: 1985-04-30
Abstract: PURPOSE:To reduce the damage to be inflicted on the X-ray lead-out window and to make thinner the film of the window by a method wherein the direction of the normal of the X-ray lead-out window and the central axis of a group of electrodes to be used for growing plasma are mutually inclined, and at the same time, the central position of the X-ray lead-out window is deviated from the extension line of the axial direction of the plasma. CONSTITUTION:X-rays 8 are irradiated from high-temperature and high-density plasma 7 on the central axis of a group of an upper electrode 5 and a lower electrode 6; and ions, electrons, high-temperature gas and so forth, which are generated in the degradative process of the high-density plasma 7, are emitted in addition to the X-rays 8. The X-rays 8 are nearly radiated isotropically from each point of the plasma 7 on the periphery of a wafer 12, while to the X-rays, the ions, the electrons and the high-temperature gas and so forth are emitted to the axial direction of the plasma. In this case, when an X-ray lead-out window 10 is set up at a position with a constant angle from the axial direction of the plasma, the damage to be inflicted on the X-ray lead-out window by the particle groups 9 can be almost ignored. Meanwhile, in the X-ray exposure, an out-of-focussed image delta=2rs/D is generated according to the diameter 2r of the X-ray source, the gap (s) between the wafer 12 and a mask 11 and the distance D between the X-ray source and the mask 11. It is not desirable for the normal of the X-ray lead-out window to make an angle to exceed 45 deg. with the central axis of the electrodes because the out-of-focussed image becomes larger when the angle exceeds 45 deg.. The effective lower limit of the inclination angle is sufficient at 2-3 deg..

Title: Noise eliminator
Inventor: YAMADA SHINTARO
IPC: F01N1/04
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To ensure a noise elimination effect at a low cost without disposing a sound absorbing material around a pipe. SOLUTION: This eliminator comprises a noise elimination body 10 in which a leading-in pipe 14 and a discharge pipe 15 are connected to each other. The body 10 comprises a partitioning wall 16 dividing the inside of the body 10, a plurality of long communication bodies 20 forming a gas flow path performing communication between ends in side of the body 10 while penetrating the partitioning wall 16 at its peripheral position in the axial direction of the body 10, and a sound absorbing material 23 mounted to a discharge pipe side of the wall 16. The communication bodies are respectively disposed at symmetrical positions at the wall 16 while a sectional shape of the gas flow path in the body 20 is long in the direction orthogonal to the radius of the wall 16, and the sectional length of the wall in the radial direction is set to be not more than 1/4 the radius of the body.  It is thus possible to enable the sound absorbing material having the required size enough to show a sufficient sound elimination performance to be mounted to the divided wall.

Title: Semiconductor wafer processing apparatus
Inventor: HIUGA KAZUAKI
IPC: H01L21/02
Filed: 1982-05-31
Abstract: PURPOSE:To obtain a uniform solder layer thickness, by attaching a chuck to a shaft which is horizontal as well as rotatable by 90 deg. and is mounted on a vertically movable block, and retaining the chuck so as to be horizontal and vertical at the top dead point and the bottom dead point, respectively. CONSTITUTION:A block 11 is vertically moved by the rotation of cams 13. A horizontal shaft 16 is rotated 90 deg. at the top dead point to retain wafer chucks horizontally. Under this state, wafers are mounted on the respective chucks. Then, the block 11 is lowered. In consequence, a cam 19 disengages from a cam 20 to allow a spring 18 to apply its force to the shaft 16 to rotate 90 deg., causing the wafers to be vertical. The shaft 16 is further lowered until the wafers are dipped in a melt of solder in a bath 21. Thereafter, the block 11 is upwardly moved, and the wafers are retained horizontally at the top dead point. This constitution permits a solder layer to be formed with an extremely uniform thickness, so that it is made possible to prevent any undesirable bridge in forming minute solder layers in close proximity to each other.

Title: M-series generator
Inventor: UEDA MASAZUMI
IPC: H03K3/84
Filed: 1990-04-06
Abstract: PURPOSE:To revise the length of M series code without changing circuit components by setting the signal of a prescribed bit location of a counter to '1', and applying ther resulting signal to a shift register when the counter counts the clock pulse of the shift register by number of stages of the register. CONSTITUTION:The output (c) of a 2nd bit location QC of a counter 7 goes to '1' when four clock pulses (a) are inputted and four 0s are outputted from the Q output of a D flip-flop 1. The signal of level '1' is fed to the D input of the D flip-flop 1 via an exclusive OR gate 6 and the Q output (b) of the flip-flop goes to '1' at the time of starting the succeeding clock pulse (a). When the number of stages of a shift register is increased to extend the length of the code, the bit location of the counter 7 to set '1' to the shift register is shifted from the 2nd bit location QC to a 3rd bit location QD. Thus, the number of stages of the shift registers is increased up to 8 stages. Then the number of stages of shift registers is revised.

Title: Fluid densitometer
Inventor: MIZOTE MASAYOSHI
IPC: G01N9/32
Filed: 1980-07-07
Abstract: PURPOSE:To facilitate setting a fluid densitometer by arrangement of measuring the fluctuating frequency of an electric current value and electric current flowing across a metallic heating element which is provided to a pipe line flowing a fluid and in the vicinity of which Karman's vortex is generated. CONSTITUTION:When a pole type vortex generator 21 is arranged to the inside of a pipe line 20 in which a fuild flows and when Karman's vortex is alternately generated in its down stream, the fluid in a slit moves periodically. And when the flow speed of the fluid that goes against a heat ray 8 increases, the heat ray 8 is cooled and its resistance Rh is reduced. As a result, since voltage V1 goes up and the output voltage V3 of an amplifier 13 also increases, an electric current Ih flowing in the heat ray 8 increases, resistance Rh increases and a bridge circuit comes again to a balanced condition. When the flow speed in the slit is maximum, it is detected by a peak value detector 17 to measure the mass flow rate and the volume flow rate is measured by a frequency detector 16, and the density of the fluid can be computed by taking ratio between both flow rates with a division circuit 19.
