Patent JP-H0949416-A (JP)
Title: Muffler for automobile
Inventor: FUJITSUBO ISAO
IPC: F01N1/08
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To lower the whole sound pressure level by forming double structure by providing an exhaust lead-in pipe coaxially in a communicating pipe closed from a resonance chamber by a lower reaches side opening part coming in contact with a partition wall plate and communicated with an expansion chamber of the exhaust lead-in pipe by an upper reaches side opening part, and disposing this double structure in the expansion chamber. SOLUTION: Exhaust gas entering an exhaust lead-in pipe 2 is expanded and diffused so as to be blown out with strong force into an expansion chamber 14 from a large number of pores 5 provided at the peripheral surface of the exhaust lead-in pipe 2, but at this time, the flow of exhaust gas passing a large number of pores 5 is disordered, so that secondary noise in a high frequency area is generated to raise a sound pressure level.  The exhaust gas blown out into the expansion chamber 14 with such action is impeded in the blowout direction in a communicating pipe 10 constituting an outer pipe part of double pipe structure formed of the communicating pipe 10 and the exhaust lead-in pipe 2, and an opening part on the lower reaches of the communicating pipe 10 in contact with a partition wall plate 9 is closed from a resonance chamber 15, so that the turbulence of the exhaust gas is faired so as to flow toward the expansion chamber 14 from a clearance 13 formed between the exhaust lead-in pipe 2 and the communicating pipe 10. The whole sound pressure level is thereby lowered.

Inventor: NISHIDA TAKASHI
IPC: C01G43/01
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To lower the height of an apparatus, to simplify the apparatus and to treat depleted UF6 . SOLUTION: The treatment apparatus for the dipleted UF6 has a first fluidized bed reaction apparatus 11 which forms UO2 F2 and dilute hydrofluoric acid by acting steam to the dipleted UF6 and a second fluidizied bed reaction apparatus 12 which forms U3 O8 and dilute hydrofluoric acid by further acting the steam to the UO2 F2 . The first and second fluidized bed reaction apparatus are flat plate type fluidized bed reaction apparatus having plural chambers which are respectively formed as multiple stages. The reaction temp. of the first fluidized bed reaction apparatus is 230 to 280 deg.C and the reaction temp. of the second fluidized bed reaction apparatus is 600 to 700 deg.C. The dilute hydrofluoric acid formed by a dry process gaseous phase reaction is separated to hydrofluoric anhydride and dilute sulfuric acid by extraction distillation using concd. sulfuric acid.  The dilute sulfuric acid is separated to low hydrofluoric acid water and concd. sulfuric acid by distillation thickening. The concd. sulfuric acid is used as the concd. sulfuric acid of the extraction distillation and the low hydrofluoric acid water is further distilled and is mixed as the hydrofluoric acid of an azeotropic compsn. with the dilute hydrofluoric acid in an extraction distillation stage.

Title: Gas sensor
Inventor: MIYAYAMA MASARU
IPC: G01N27/419
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To measure the concentration of a specified gas with high sensitivity by further changing the resistance of a second electrode by applying a pump voltage between first and second electrodes. SOLUTION: The resistance of a second electrode 16 drops as the result of sensing a specified gas CO to increase the current value A1 carried in the second electrode 16. Since the current value A2 carried in a base body 12 is increased by the reduction in resistance of the second electrode 16, the pumping quantity of oxygen by the base body 12 increases, whereby the oxygen partial pressure near the second electrode 16 is reduced, resulting in a further reduction in resistance of the second electrode 16. Consequently, the pumping quantity of oxygen by the base body 12 is further increased. This amplifying effect is repeated, whereby the measuring sensitivity of the specified gas CO is remarkably improved.

Title: Disk surface defect-inspecting device
Inventor: ISHIGURO TAKAYUKI
IPC: G01B11/30
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To selectively detect a circle scratch defect and accurately discriminate a circle scratch defect from the scratch defect for detection by condensing only scattered light with sharp directivity in the prescribed direction. SOLUTION: A light reception system OR1 for detecting a circle scratch defect is composed of a condensing lens ER that is arranged in specific elevation from a disk surface, a photo detector D3 for detecting light being condensed by the condensing lens ER, and an optical fiber OF for propagating light being condensed from the condensing lens ER to the photo detector D3. When the circle scratch defect exists, a laser spot is scattered.  Therefore, with a position where scattered light appears most strongly, since the scattered light appears most strongly in the direction opposite to the incident angle of the laser beam at a position of back scattering of 25 degrees, namely an elevation of 45 degrees from a disk surface when the incidence angle of a laser beam being applied to, for example, a first light transmission system L1 is 70 degrees, the condensing lens ER is arranged at that position for efficiently condensing the back scattering light.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce the interruption time by supplying a basic clock from a basic clock source to a digital PLL with a fixed oscillator so as to operate a frame counter so as to shorten a transmission time. SOLUTION: The circuit has a synchronization pattern matching detection circuit 3, a comparison pattern generating circuit 5, a selector 15 and a fixed oscillator 7 and supplies a basic clock of a basic clock source to a digital PLL 6. The circuit 5 generates a true synchronization pattern and n-sets of patterns with a Humming distance (n) of allowing an error to the true synchronization pattern. Furthermore, the circuit 3 selects any of the n-sets of comparison patterns in the case of synchronizing state output, and a selector 20 selects only one true synchronization pattern at the time of asynchronous state. Then a frame counter 4 generates a window pulse 10 used to pass only a region including the synchronization pattern of data in the synchronizing state and a gate 21 passes the entire time region in the non-synchronization state.  Then the oscillator 7 supplies a basic clock from the basic clock source to a digital PLL 6, the PLL 6 provides the clock to the counter 4, which is activated.

Abstract: PURPOSE:To accurately judge the voltage of a power supply on a primary side without receiving the effect of the rise in temp. of load or winding, by reading the output voltage before rectification on a secondary winding side at the time of non-load of a power supply transformer and judging the input side voltage of the power supply transformer on the basis of said voltage. CONSTITUTION:A control circuit 12 is connected to the secondary side output of a power supply transformer 1 through a rectifying circuit consisting of a diode 6 and a smoothing condenser 7. Then, a condenser 15 is charged with the voltage in the voltage change region from the zero cross point of time of the secondary side output before rectification to the charge start point of time of the smoothing condenser 7 for a definite time and the voltage of this condenser 15 is detected to detect voltage at the time of non-load of the power supply transformer. By this method, the voltage of a power supply can be judged regardless of the magnitude of the load of secondary winding or the temp. of said winding. As a result, the judge accuracy of the voltage of the primary side power supply becomes extremely well.
