Title: System and method for thermally decomposing contaminant adhering to cast sand and buriving resulting gas
Inventor: ROORANDO POORU ARUFURETSUDO GI
IPC: B22C5/08
Filed: 1994-10-28
Abstract: PURPOSE: To efficiently and effectively treat foundry sand by combusting a flame accompanied by excess oxygen at an angle within a specific range from an axis, thereby forming an exhaust gas containing oxygen and the roasted foundry sand. CONSTITUTION: The foundry sand contaminated with organic materials is supplied into a container 13 of a rotary kiln 3. The container 13 is regulated by using a second rotating means 21 in such a manner that the axis of the container exists at an angle within about 0 deg.±10 deg. when measured from a horizontal plane. The container is rotated by a first rotating mean 17 around the axis. The at least one flame accompanied by the excess oxygen is combusted by using an oxygen-combustion burner 32 at the angle within the range of about 0 to ±30 deg. when measured from the horizontal plane or axis within the container 13, by which the exhaust gas and the roasted foundry sand and formed. As a result, the heat process useful for effectively and efficiently treat various kinds of the sand may be established.

IPC: G01N29/00
Filed: 1988-11-15
Abstract: PURPOSE:To make it possible to compute the mechanical constants of a material at high accuracy by vibrating the material, and obtaining the constants by a resonance method by which the intrinsic resonance frequency of the material is measured. CONSTITUTION:A signal having a specified frequency is inputted into an exciting device 2 which vibrates a material 1, e.g. a speaker which generates sound waves. The vibration of the material 1 which is detected with a pickup 3 is measured in a frequency analyzer 4. A CPU 5 communicates with the analyzer 4 and obtains the mechanical constants of the material 1. The material is vibrated with the device 2. The vibration is detected with the pickup 3 and measured by the use of the analyzer 4. The transfer function is obtained in the CPU 5. Whether the vibration is bending vibration or torsional vibration is judged. Elastic modulus and rigidity are obtained by specified expressions, respectively. Therefore, the accurate resonance frequency of the material is readily determined, and the mechanical constants of the material are obtained accurately without destructing the material.

At the time of generating a contour point sequence between the points A, B, for instance, a contour generating starting point 201 is calculated from the coordinate of the starting point A first. The value (E0) of the initial residual 203 at this time is obtained from an expression: E0-f1(x1).¦y2-y1¦/¦x2-x1¦+f2(y1). The contour point sequence 206a-206e is then obtained in succession by a residual recurrence formula arithmetic means 107. High-quality characters faithful to the original characters can be thereby obtained.

Abstract: PURPOSE:To dig a tunnel correctly by providing a plurality of intermediate targets via a target pedestal between a reflecting mirror and a face of the tunnel and, providing an operating apparatus for remote-controlling a laser scanner near the face of the tunnel. CONSTITUTION:When a power switch of a regulator 20 is turned ON to drive a laser scanner 10, a laser beam 60 is projected. This beam 60 is polarized along a direction of an axis of the tunnel through a reflecting mirror 30, passing through a through-hole of an intermediate target 40, to a face 2 of the tunnel to be irradiated with a laser spot 70. Thereafter, an operational personal computer controls the rotation of the scanner to project the beam 60 to the face 2 through a plurality of mirrors 30 and targets 40. Accordingly, a reference cross section to dig the tunnel which is drawn by nearly continuous points is projected to the face 2 by the spots 70. Therefore, a correct digging line can be obtained by the spots 70, and this digging line can be used as a guide to dig the tunnel, thus improving the digging accuracy and efficiency.

Title: Am signal demodulator
Inventor: KANESU NORIYUKI
IPC: H03D1/00
Filed: 1990-10-25
Abstract: PURPOSE:To exclude noise output completely in case receiving of an AM signal to be input is not in a normal condition by 'breaking' the demodulation action in switching circuit such as analog multiplexer or analog switch. CONSTITUTION:In the condition of receiving an AM signal 101 in response to the time when detuning, receiving a weak radio wave, or the like if phase synchronous state at a level less than a predetermined value is not normal, a phase lock detecting signal 103 is neither generated nor outputted. For this reason, to analog multiplexer 1, a phase lock detecting signal 103 is not inputted from a carrier wave/control signal generating circuit 2, and hence the carrier wave demodulating function of analog multiplexer 1 is maintained inactive, and the signal output from analog multiplexer 1 is completely cut, thereby neither demodulating signal nor noise output is outputted.

Filed: 1987-11-16
Abstract: PURPOSE:To simplify the circuit constitution by using an error bit represented by a low-order bit of an output of an A/D converter as an address input of a ROM and outputting only branch metric so as to decrease the input/output bit of the ROM. CONSTITUTION:A branch metric calculation circuit 2 consists of a symbol selection circuit 21 and a ROM 22, a symbol is discriminated by a soft discrimination output of the A/D converter 1 and calculates a branch metric to the symbol. Then a hard discrimination output represented by a high-order digit of the soft discrimination output of the converter 1 and the most significant digit of an error bit represented by a low-order digit are given to the circuit 31 and an error bit is given to an address input of the ROM 22 to output the branch metric. That is, as the address input of the ROM 22, an error bit represented by the low-order bit being the output of the converter 1 is used and only the branch metric is outputted and a common storage content is utilized to all symbols. Thus, the input/output bit of the ROM 22 is decreased to simplify the circuit constitution.

Abstract: PROBLEM TO BE SOLVED: To detect a defect quickly and surely by projecting an illumination light to a light transmitting container turning about an axis, detecting the intensity distribution in the direction perpendicular to the axis of reflected light, and then making a decision whether a defect is present based on the intensity distribution. SOLUTION: A glass bottle 11 located in an inspection area on a conveyor is turned about the axis thereof by one revolution or more in about 0.3sec.

IPC: F04D29/66
Filed: 1994-10-27
Abstract: PURPOSE: To provide a fan with a muffling box which is so constituted as to prevent the the occurrence of a vortex and a swirl flow to the air passage of a muffling box, prevent lowering of performance of a fan, and prevent leakage of noise generated from a sound source, such as a fan, to the outside. CONSTITUTION: Formation of a fan with a muffling box is such that a fan with a muffling box comprises a muffling box 1; and a fan 2 arranged in the muffling box 1, air sucked through the suction port 3a of the muffling box 1 is guided through a passage 6, formed in the muffling box 1, to the suction port 2a of the fan 2, and the air is pressurized by the fan 2 and discharged through the delivery port 4a of the muffling box 1. A passage running from the suction port 3a of the muffling box 1 to the suction port 2a of the fan 2 is formed of a muffling material so that a sectional area and a sectional shape are not rapidly changed from the suction port 3a to the suction port 2a of the fan 2.

Title: Electrostatic induction thyristor with split gate type cathode short-circuiting structure
Inventor: TAMAMUSHI NAOSHIGE
IPC: H01L29/74
Filed: 1992-10-02
Abstract: PURPOSE:To obtain a high speed turn-off performance by suppressing storage effect of minority carrier (hole) near a cathode side by feeding part of holes injected from an anode region to a cathode electrode short-circuited to a shielded gate electrode through a first gate region. CONSTITUTION:At the time of turning OFF a thyristor, most of a hole current flowing from an anode side flows to a first gate (short-circuiting gate) 31, and this amount is gradually reduced. A hole current flowing to a cathode 2 flows to a second gate (control gate) 32 which is negatively biased. Accordingly, since a hole current to be controlled by the control gate (second gate) 32 is shared to the first gate by a split gate structure, it may be extremely lower than the case of a common gate. Since a split gate structure is employed, injected hole amount from the gate is small, and hence storage effect of the minority carrier (holes) is suppressed.
