Title: Pwm pulse demodulator
Inventor: ENDO TAKESHI
IPC: H03K9/08
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To precisely provide a stable demodulation output for a PWM pulse whose pulse width is very small through the use of the comparison amplifier of a high gain by negatively feeding back PWM pulse demodulation output to input pulse amplitude. SOLUTION: In the signal pulse outputted from a switch circuit 21 constituted of CMOSFET, width is matched with an input pulse and amplitude becomes feedback voltage VF. The signal pulse is smoothed in a filter 22 and the comparison amplifier 23 compares it with reference voltage. Then, it is amplified and is outputted to a terminal 15 as demodulation output. The output is inputted to a differential amplifier 26 through a high pass filter by a capacitor 28 and resistances 29 and 31, is inversely amplified and output voltage VF is negatively fed back to the switch circuit 21 (low pass filter as a whole loop). When the duty ratio of the input signal pulse exceeds 50%, the output of the comparison amplifier 23 increases and feedback voltage VF reduces by increased quantity. The increase of the comparison amplifier 23 stops to a level corresponding to input pulse width.

Title: Decarburizing method of molten steel
Inventor: WAKAMATSU KAZUHIKO
IPC: C21C7/00
Filed: 1983-06-14
Abstract: PURPOSE:To decarburize efficiently a molten steel such as a high Cr stainless steel by blowing inert gas and oxygen to the molten steel flow falling from a tap hole. CONSTITUTION:Inert gas is blown through an annular pipe 5 provided in the bottom of a ladle so as to enclose a ladle nozzle 3 of a furnace and many pipe nozzles 6 attached in the lower part thereof to the molten steel flow 4 flowing down from a top hole or the nozzle 3. Pure oxygen is further blown to the molten steel flow 4 from the nozzles 8 of a large-diameter annular pipe 7 provided to the pipe 5 on the outside of the inert gaseous flow. A decarburization reaction is thus induced by oxygen 10 at the reaction point 12 of the boundary between the inert gaseous flow 9 and the molten steel flow 4. The reaction area between the molten steel and the oxygen is increased and the decarburization reaction of the molten steel at the low carbon concn. to be rate-determined by the diffusion of the carbon in the molten steel is easily accelerated by the above-mentioned method.

Title: Intake device of diesel engine equipped with supercharger
Inventor: HITOMI MITSUO
IPC: F02B37/00
Filed: 1988-04-27
Abstract: PURPOSE:To increase the output torque in a range from a low speed region to a high speed region by setting the inertia harmonization revolution speed in each single cylinder to a supercharge pressure suppressing revolution speed or less and setting the resonance harmonization revolution speed of intake between the cylinders in each cylinder group less than a restriction revolution speed at the supercharge pressure suppressing revolution speed or more. CONSTITUTION:Since the inertia harmonization revolution speed for intake in each single cylinder 2a-2d is set at the value less than the supercharge pressure suppressing revolution speed by a waste gate valve, the inertia harmonization of intake is generated in the cylinder of a cylinder group 2a, 2d (or 2b, 2c), and intake is supercharged into the cylinder, and the output torque is increased by increasing the intake charge quantity. Further, since the resonance harmonization revolution speed between the cylinders of the above-described cylinder group is set less than a restriction revolution speed for suppressing the excessive revolution of an engine in case of at least the above- described supercharge pressure suppressing revolution speed and in the whole load operation, the intake resonance harmonization is generated in the actually used revolution region, and the volume efficiency of intake lower, and the fuel injection timing is advanced, and the fuel injection quantity can be increased.

Title: Method for preventing adhesion of scales on pipe for supply of washing water to dust collecting plates, nozzle and dust collecting plate in wet type electric dust collector
Inventor: TAKAKURA YOSHIKATSU
IPC: B03C3/16
Filed: 1988-04-30
Abstract: PURPOSE:To enhance the removal effect of hard scales growing gradually by periodically stopping the supply of water for use in the washing of dust collecting plates in a wet type electric dust collecting device, so that steam alone is supplied to a header pipe for carrying the washing water to the dust collecting plates. CONSTITUTION:The supply of water for use in the washing of dust collecting plates in a wet type electric dust collector 1 is stopped periodically, so that steam alone is supplied to a header pipe 3 for carrying the washing water to the dust collecting plates. This method permits scales to be separated from pipe walls due to the differences in the amount of thermal expansion between the pipe wall and the solidified scale while the latter is blown off with the steam pressure and thereby the removal effect of the hard scales growing gradually is enhanced.

Abstract: PURPOSE:To prevent erroneous function by inputting an erasure preserving signal immediately after first time application of power source onto an electronic controller and erasing a nonvolatile trouble code memory only when an erasure signal is inputted immediately after second application of power source. CONSTITUTION:An anti-lock brake controller 10 connects a testing device X through a check terminal coupler 6 prior to delivery or when periodic inspection is carried out, then detects normality/abnormality through self diagnosis function and displays the result in code form on a monitor thereafter stores the data in a non-volatile trouble code memory 5.

Abstract: PROBLEM TO BE SOLVED: To attain the automatic stop/cancel of the call transfer service to a third party by identifying a state of a speech channel when a new call is received in a busy mode and transferring automatically the new call all to an automatic answering service center if the speech channel is kept in a data communication mode. SOLUTION: If an interruption call is received from a telephone set 3 of a subscriber C via a speech channel that is kept in a communication mode between a telephone set 1 of a subscriber A and a telephone set 2 of a subscriber B, an exchange 10 hunts the speech channel by a speech channel hunting function 5, draws in the speech channel by a speech channel draw-in function 6 and samples the speech channel by a speech channel sampling function 7. If a speech data identifying function 8 identifies that the speech channel is used for the communication of data by the result of the function 7, a speech channel switching function 9 transfers automatically the call received from the telephone 3 to an automatic answering service center 4. As a result, the complicated operations can be eliminated when the communication of data is started or ended.

Abstract: PURPOSE:To accurately find the mean line width of a pattern by finding the correlation between the output waveform of a charged particle ray scanned on the pattern of a base and signal waveforms obtained by measuring previously various reference samples whose pattern line widths are already known. CONSTITUTION:The pattern 2 formed on the base 1 is irradiated with the charged particle ray 3 and reflected charged particles 4 exiting from the pattern 2 are detected by a detector 5. Then, an output waveform shown in a figure is obtained from the detector corresponding to time variation. When the scanning speed of the charged particle ray 3 is denoted as S and the position of the scanning start point is denoted as Xo, the relation between the time (t) after the scanning start and the position X is expressed by X=Xo+St. Further, the width of the pattern 2 is represented by the mean line width of the width of the surface and the width that the pattern 2 contacts the base 2 to. Reference samples which are variously different in pattern width as to the material of the base 1 and the material of the pattern 2 are prepared. Then, the statistical correlation between the output signal waveform of the detector 5 and signal waveforms at the time of various mean line widths which are already known by measuring the reference materials is found, so that the maximum mean line width when the coefficient of the correlation is maximum is the mean line width of the pattern 2.
