Title: Compressed natural gas charging device
Inventor: OOTAKA AKIFUMI
IPC: F17C13/04
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent a remarkable temperature drop caused by the adiabatic expansion of compressed natural gas from occurring near a one-way valve by providing a restriction with a degree of restriction larger than that of the one-way valve in a gas charging path on the downstream side of the one-way valve. SOLUTION: When a restriction 391 with a degree of restriction larger than that of a one-way valve 371 is installed on the end of the downstream side of a gas charging path 311 , a temperature drop occurs near the restriction 391 by the adiabatic expansion caused when compressed natural gas flows through the restriction 391 . Because natural gas causes a pressure loss when it passes through the one-way valve 371 , a pressure difference across the restriction 391 becomes relatively small, the degree of the adiabatic expansion is also suppressed, and a temperature drop near the restriction 391 also becomes relatively small.  Then a pressure difference across the one-way valve 371 is smaller than that across the restriction 391 , and a temperature drop near the one-way valve 371 becomes further gentle, and thus a remarkable temperature drop is prevented from occurring near the one-way valve 371 . Thus rapid charging of gas is enabled.

Title: Manufacture of semiconductor device
Inventor: TAKAHASHI MASASHI
IPC: H01L21/8242
Filed: 1993-02-02
Abstract: PURPOSE:To form an uneven part and a flat part on the same substrate at the same time, by using an oxide film as mask function, by a method wherein, on the same substrate, a silicon oxide film is previously formed on one part out of the part whose surface is turned into an uneven form and the part whose surface is flattened. CONSTITUTION:After a poly silicon film 6 is deposited on a substrate and an oxide film 6a is formed on the film 6, the oxide film 6a is left by etching only the part whose surface is to be flattened. A natural oxide film on the poly silicon film 6 is eliminated. By heat treatment after elimination, only the surface on the poly silicon film 6 which is not covered with the oxide film 6a is turned into an uneven form. Since the oxide film 6a acts as a mask, the poly silicon film 6 under the oxide film 6a is not affected by the heat treatment and flat. When the oxide film 6a is eliminated with hydrogen fluoride solution, the part whose surface is uneven and the part whose surface is flat can be formed on the same substrate.

After the discharge of the fluid is completed, the motor 18 is driven to rotate the shutter 11 to the position where the protruding parts 15 of the shutter 11 are opposed to the nozzle orifices 9a. As a result, the nozzle orifices 9a are closed and even when the fluid remains in the passage 10, no liquid dripping is generated.

IPC: H01L21/027
Filed: 1978-02-13
Abstract: PURPOSE:To obtain electron beams of the section desirable in size invariably, by correcting a  length signal of side Y corresponding to the variation of the length signal of side X of electron  beams of the reactangular section. CONSTITUTION:By the command of computer 4, register 5 attain D/A conversion 6 and amplification 7 of a signal to make deflection (dxdy), and gate 14 is opened to reset counter 23. Clock  pulse CP18 after being gated 14, counted 15 and D/A-converted 16 is amplified 17 and deflection- scanned 13, so that wire 10 will be irradiated with electron beams at a constant speed. Primary  and secondary differential processes 20 and 21 of an electron-beam current decreasing gradually  are performed to generate 22 pulses of the pulse width equal to the interval between secondary  differential signal peaks and, in consequence, gate 27 is opened to count 23 CPs, so that its  discrete value will be stored in comparator 24. Next, when side Y is changed with side X of the  beam section kept constant, a deflection component is generated in the X direction with side Y not  in parallel to deflection direction (dy). Therefore, CP discrete value 23 at this time is compared  24 with the stored value, the difference is D/A-converted 25 for matrix control 26, and deflection  in the X direction is made with the polarity inverted. Consequently, the section of electron beams  passing through mask (m2) becomes desirable in size.

Filed: 1989-01-26
Abstract: PURPOSE:To ensure an accurate temperature control by inputting the highest potential value of a side of a bridge circuit including an impedance element as a stable potential via a peak holding circuit even in the case the potential changes unstably and also in an AC waveform caused by the temperature change. CONSTITUTION:The resistance value of an impedance element 4 is increased with the temperature rise. Then the capacity of an insulated layer 5 is reduced and the resistance of the layer 5 is increased. As a result, the voltage of a joint part (a) receives the influences of an AC power supply 1 via the layer 5 and has an AC voltage waveform. Then the voltage of the part (a) is stabilized via a peak holding circuit 20. The potential of a joint part (b) which is set by a temperature setting resistor 8 is compared with the potential of the part (a) via a comparator 19. When the potential (comparison potential) of the part (a) which is turned into a direct current by the circuit 20 is coincident with the potential (reference potential) of the part (b), the energization is stopped to a heater line 3. In such a manner, the accurate temperature control is attained.

Abstract: PURPOSE:To simplify a device by using a hologram which uses a focusing luminous flux generating means and a tracking luminous flux generating means in common. CONSTITUTION:Pieces 72 and 71 of luminous flux for tracking are made incident on planes almost perpendicular to a plane formed of reference luminous flux 70 for generating pieces of luminous flux for focus adjustment and video signal reading and luminous flux 73 for focus adjustment at angles + or -phi to the planes, thereby generating a hologram 74. This is reproduced to obtain signal readout luminous flux, luminous flux 76 for focus adjustment, and pieces 77 and 78 of luminous flux for tracking. The pieces 77 and 78 of luminous flux are converted on both sides of a video signal track of a video disk 49 and their reflected light beams are detected by detecting element 81 and 82 for tracking to drive an optical system so that the signal reading luminous flux does not deviates from the track. The luminous flux 73, on the other hand, is reflected by the disk 49 and passes through a half-mirror 44 to strike on an element 50 for focus detection. Thus, the hologram is used, so the device, becomes extremely simple. Further, the hologram can be copied, so it is inexpensive.

Abstract: PURPOSE:To attain a high speed processing and to miniaturize a circuit scale by using simple majority decision logic to select the content of a decoding path memory. CONSTITUTION:The optimum value output of a path memory 14 in a Viterbi decoding is decided not by an accumulated measured value of a metric memory but by the majority decision of a majority decision circuit 18 from the output of the path memory 14 itself. That is, in the case of applying decoding in a required multi-stage, the output stage bits of path memories are identical in most case and when the bits are outputted as they are, it is not required to select plural path memories intentionally from the maximum value of the accumulated measuring of the metric memory. Thus, the maximum value retrieval processing in the Viterbi decoding is facilitated and the circuit scale is miniaturized.
