Title: Signal transmission equipment
Inventor: UCHINO TADAHARU
IPC: H04B7/00
Filed: 1987-02-21
Abstract: PURPOSE:To simultaneously adjust the sound pressure level of 1st and 2nd sound generating means by applying remote control to the sound pressure level of the 2nd sound generating means depending on the sound pressure level of the 1st sound generating means. CONSTITUTION:A transmitter 2 has a front sound generating section 4 and a rear sound generating section 5 being the 1st sound generating means arranged in front of and at the back of a listener and a receiver 3 has a rear sound generating section 6 being the 2nd sound generating means arranged at the back of the listener. In this case, when the sound level of the 1st sound generating means is changed, the sound volume control data changing the sound volume level of the 2nd sound generating means is sent from the transmitter 2 to the receiver 3 while being included in a transmission signal. Thus, the sound level of the 1st and 2nd sound generating means is changed at the same time.

Title: Crucible of semiconductor single crystal pulling apparatus
Inventor: IMAYOSHI MASAFUMI
IPC: C30B15/12
Filed: 1992-01-28
Abstract: PURPOSE:To obtain a semiconductor single crystal having high defect-free ratio by opening a through-hole connecting the inner and the outer surfaces of a side wall of a graphite crucible holding a quartz crucible, forming a ring-shaped groove on the inner circumference of the graphite crucible and placing a ring-shaped lid on the upper end of the quartz crucible. CONSTITUTION:Metals accumulated at the inner side 4c of the curved part of a graphite crucible 4 meet a through-hole 4a in the course of rising through a gap between the inner surface of the graphite crucible 4 and an outer surface of a quartz crucible 5, pass through the hole as shown by an arrow in the figure and move to the outer side of the side-wall of the graphite crucible 4. Accordingly, the intrusion of metals into molten silicon 6 is remarkably suppressed and the deposition of the metals on a just-solidified silicon single crystal 8 is also decreased. The inner surface of the through-hole 4a is opened on the ring-shaped groove 4b on the inner circumference of the side wall of the graphite crucible 4 to prevent the rise of the metals through the space between the through-holes. A lid 9 composed of a ring-shaped disk part 9a, a small-diameter jaw 9b and a large-diameter jaw 9c is placed in such a manner as to contact the lower face of the small-diameter part with the upper end of the quartz crucible 5 to prevent the intrusion of metals as shown in the figure.

Title: Flowmeter of powder for solid-gas mixed phase flow
Inventor: WATANABE HISAO
IPC: G01F1/66
Filed: 1983-03-09
Abstract: PURPOSE:To measure a powder flow rate in wide range from low to high concn. ranges by providing interposingly a bent tube en route in a piping or using the bent part of the existing piping. CONSTITUTION:In case that the solid-gas mixed phase fluid flows in the piping P, since the detecting end of a sensor 3 provided at an entrance part is depressed slightly from the inner wall of the tube, the powder scarcely impinges directly at the end. Therefore the sensor 2 catches the sound of mutual impinging of the powders passing the transverse section of the entrance part of the bent tube 1. Concerning the powder flow near the center part of the tube 1, large particles 8 can't make a turn in the tube 1 due to the large inertia force, and impinge at the inner wall surface of outside of the center part of the tube 1. Since the sensor 3 is provided so that the surface of the detecting end coincides with the inner wall of the tube 1, the particles 8 impinge at the sensor 3, the friction sound is generated, and is picked up at the sensor 3. Concerning the powder flow at the exit part of the tube 1, since small particles 9 impinge at inner wall of the tube near the exit, the particles 9 impinge at the sensor 3 and the friction sound is generated. The quantity of the particles 9 can be obtained similarly to the previously described case of the particles 8 from the intensity and frequency of this friction sound.

Title: Signal processor for optical pulse tester
Inventor: YAMADA TAKAYUKI
IPC: G01M11/00
Filed: 1992-02-26
Abstract: PURPOSE:To remove noise in a short time by providing an adapting and smoothing circuit, taking a ratio of error dispersion in an entire signal to error dispersion within a predetermined section, and outputting an output signal of a optical pulse tester or a neural network according to the degree. CONSTITUTION:A neural network 7 removes a noise component in an output signal of this pulse tester and outputs it. An adapting and smoothing circuit 8 has respective output signals from the neural network 8 and the pulse tester as its inputs and takes a ratio of error dispersion on the two entire signals and error dispersion within predetermined sections. When the error dispersion within the sections is larger than the error dispersion over the entire signals, the output signal from the pulse tester is output. If the error dispersion over the entire signals and the error dispersion within the sections are approximately equal to each other, the output from the neural network 7 is output. Thus noise can be removed without losing Fresnel reflection accuracy also in a short time.

Title: Recording apparatus and its using method
Inventor: YUI KOJI
IPC: B41M5/382
Filed: 1995-02-03
Abstract: PURPOSE: To prevent an excessive recording material from scattering/adhering undesirably, by setting a removing means which causes the recording material to fly and adhere to a recording medium to be recorded and removes the excessive recording material not adhering to the recording medium. CONSTITUTION: An excessive vaporized dye 132 not adhering to a paper to which the image is transferred (printing paper) and flying to scatter is sucked through a suction port in the vicinity of a vaporization part 17. The dye 132 is collected by a filter 2 and removed. The dye is hence prevented from adhering to light-emitting and photodetecting sides of an optical sensor or the like which is important for controlling of the operation of a printer, thereby ensuring normal operation of the apparatus. Moreover, excessive transfer (scumming) to a part of a low density (including a white part) of a printed image is prevented. The transfer paper is also prevented from adhering to a carrier roller. Accordingly, the image quality is maintained good. The suction of the dye is properly effected when the interior of the suction port 1 is reduced to approximately 0.7-0.8atm.

Title: Loop circuit for channel
Inventor: ABE SHOICHI
IPC: H04M7/04
Filed: 1985-02-28
Abstract: PURPOSE:To obtain a loop circuit with small power consumption regardless of the source voltage of the channel by limiting the value of current flowing through the lines to a prescribed value and less when the voltage between the lines is below a specified voltage and by releasing the limitation when the voltage once exceeds the specified voltage, and thereby maintaining an approximately constant resistance. CONSTITUTION:In case the voltage between the signal line 100 and 200 rises, the base voltage of a transistor Q0 is limited by a reference diode ZD1, and the current of the transistor Q0 is also limited. That is, the loop circuit is limited in a state of the first limit-current. When a voltage lifting power source is connected between the signal lines 100 and 200 and the voltage between the two exceeds the specified value, a current flows through a reference diode ZD0 and a resistor R2, and a current is supplied to the base electrode of a transistor Q1 turning the transistor Q1 on. Consequently, the base voltage of the transistor Q0 is determined by resistors R0 and R1, and the current that flows through the transistor Q1. That is, the current flowing in the loop circuit is released from the limit.
