Title: Posture control device in agricultural working machine
Inventor: OKADA SATORU
IPC: G05D1/08
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To improve a response property in a control and also reducing the rolling of a traveling machine body itself so as not to make the detection by an angular velocity sensor too sensitive and reducing the number of actions of a hydraulic cylinder for performing the rolling control in performing a posture control such as the rolling control of a working machine such as a seedling planting device in an agricultural working machine. SOLUTION: This posture control device in an agricultural working machine is provided by mounting rear wheels 5 at the rear part of a traveling machine body through a left and right pair of swing cases 4, installing an angular velocity sensor 58 at the near side to the swing cases 4 of the traveling machine body, while installing an inclined angle sensor 51 at a seedling planting device linked to the rear part side of the traveling machine body through a parallel linking mechanism 11, and performing the rolling control by a hydraulic cylinder installed between a parallel linking mechanism 11 and the seedling planting device. When the rolling is absorbed by the swing case 4, the detected value of the angular velocity sensor 58 becomes small, and the acting amount and the number of the actions of the hydraulic cylinder can be reduced.

Title: Rare earth iron-based magnet
Inventor: INOKOSHI YOSHIO
IPC: H01F1/053
Filed: 1990-10-01
Abstract: PURPOSE:To obtain a magnet base metal having high corrosion resistance and high maximum energy product by specifying the crystal grain diameter of V2O5 dispersed in a magnet alloy. CONSTITUTION:It is designed that the crystal grain of V2O5 dispersed in a rare earth iron-based magnet alloy containing 80wt.% or more of R2(CoxFe1-x)14 B1 (R = one kind or combination of two or more kinds out of Ce, Pr, Nd, Tb, and Dy) tetragonal crystal and 0.1-0.2wt.% of V2O5 may be 0.1-10mum. That is, a V2O5 crystal grain of 0.1mum or less induces small effect in improving corrosion resistance, and 10mum or more enhances decreases in magnetic characteristics, particularly maximum energy product; therefore, the size of the crystal grain should be restricted. This design can provide a magnet base metal of high corrosion resistance having high maximum energy product.

Title: Burner for gas cooking appliance
Inventor: KODERA HIROSHI
IPC: F23D14/06
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a burner for a gas cooking appliance which can improve the external appearance of a flame. SOLUTION: A burner for a gas cooking appliance having a constitution wherein a burner cap 3 is set on a burner base 2 of a burner main body 1 and a large number of burner ports 4 are provided in a line in the circumferential direction of the burner cap 3 between the outer peripheral part of the burner cap 3 and the upper side of the burner base 2. A burner port 4a for ignition communicating with the lower surface side of the burner base 2 is formed in the burner base 2. An igniting means for the burner port 4a for ignition is provided on the lower surface side of the burner base 2. An ignition flame coming out to the lower surface side of the burner base 2 from a slit 5 is led to the outer circumference of the burner cap 3.  Since the ignition flame coming out from the burner port 4a is thereby made to go around to the outer circumference of the burner cap 3 from the lower surface side of the burner base 2, the fore end of the ignition flame hardly projects to the outer circumference of the burner cap 3 and so the ignition flame is not conspicuous, unlike the one in usual cases. Thus, flames around the whole circumference of the burner cap 3 are made uniform and the external appearance of the flames is improved.

Title: Soot blower automatizing device
Inventor: FUJIWARA TOSHIKATSU
IPC: F23J3/00
Filed: 1989-10-12
Abstract: PURPOSE:To make it possible to blow soot at a suitable timing by the constitution that a fouling factor estimation section which inputs observation values from a plant outputs the fouling factor of a heat exchanger and it sends control signal to a soot blower when the fouling factor goes beyond a threshold value and it lets the soot blower blow soot for a certain time. CONSTITUTION:A fouling factor estimation section 3 inputs observation values such as the temperature, pressure, etc. from a plant 1 which is provided with a heat exchanger and employs least square method to output a fouling factor 4 of the heat exchanger calculated based on a formula. A threshold value setting device 6 sets a threshold value of the fouling factor 4. A comparator 5 inputs the threshold value from the threshold setting device 6 and inputs the fouling factor 4 from the fouling factor estimation section 3 and outputs a signal as a result of comparison. A command device 7 inputs signal from the comparator 5, and when the fouling factor goes beyond the threshold value, it outputs a control signal to a soot blower 8 to drive it. In the formulae, W=CfWf+CmWm, and Cf is the specific heat value of the fluid in the heat exchanger pipes, Cm the specific heat value of the heat exchanger pipes, Wf the weight of the fluid in the heat exchanger pipes, Wm the weight of the heat exchanger pipes, DELTAt the sampling period, and thetam(-1) represents the average temperature of the pipes the time DELTAt before.

Title: Electronic feeding circuit
Inventor: TABU TAKASHI
IPC: H04M19/00
Filed: 1984-12-14
Abstract: PURPOSE:To attain circuit integration by providing an amplifier circuit whose signal is fed back to lines A, B corresponding to the lines A, B. CONSTITUTION:Since resistors RA1, RB1 have identical high resistance value, only an in-phase signal appears at the connecting point N in both the lines A, B. Since an output v0 of an operational amplifier OAA is a difference of output between that based on a non-inverting input and that based on an inverting input, when the output v0 is zero, the impedance to the in-phase component viewed from the line A is only the resistor RA7. Since the termination impedance is constant, the resistance RA7 is multiplied by (n) to a differential signal due to the non-inverting feedback from the impedance ZA2, giving an impedance of 600 or 900OMEGA. Since the DC component is shut by capacitors CA1, CA2, the DC feeding resistance is 200OMEGA by selecting the resistors RA2, RA3.

Then the passing of idle data channels by the number of operating request signals at the downstream of the incoming transmission line 10 from its own station is calculated and the data is written in the succeeding idle data channel. Then in order to make an operation state signal area B busy, a data and a signal representing the data channel busy state are sent via the branch insertion means 1-1, 2-1 and 3-1. Thus, it is possible to eliminate the insertion means to the outgoing transmission line and when the system is applied especially for the optical transmission line, number of photocouplers is decreased to attain the inexpensive system.
