Title: Four-wheel driving type agricultural tractor
Inventor: OKITA NAOKI
IPC: B60K17/34
Filed: 1983-06-22
Abstract: PURPOSE:To permit to turn with a small radius of turning by a method wherein a speed increasing mechanism, increasing the peripheral speed of front wheels to 1.5 times of the same of rear wheels when a running speed is low and the operating angle of steering for the front wheels has become more than a preset value, is operated. CONSTITUTION:The power of an engine 5 is transmitted from a speed change mechanism 11, consisting of main and sub speed change mechanisms 9, 10, to a rear wheel differential mechanism 13 through a main clutch 8, while the output of the speed change mechanism 11 is transmitted to a front wheel differential mechanism 18 through a transmitting shaft 15 and the speed increasing mechanism 16. The speed increasing mechanism 16, increasing the average peripheral speed of the front wheel 1-1.5 times of the same speed of the rear wheel, is provided. The speed increasing mechanism 16 is constituted so as to obtain a standard condition, in which the front wheel 1 is driven with the average peripheral speed somewhat higher than the same speed of the rear wheel 2 upon connecting first hydraulic clutch 26, and a double speed condition, in which the front wheel 1 is driven with the average peripheral speed higher than two times of the same speed of the rear wheel 2. Respective clutches 26, 27 are controlled by a control unit so as to be switched to the double speed side automatically upon turning on the end of a cultivating field.

Title: Position detecting apparatus
Inventor: KAIHARA SHOICHIRO
IPC: G01B13/02
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus in which the distance between a gas discharge port and an object to be measured can be set to be large and which is situated only on one side of the object to be measured by a method wherein the air in an air chamber is sucked and the differential pressure between a negative pressure inside the air chamber and atmospheric pressure is detected. SOLUTION: A pipe 13 for differential pressure measurement is attached in a position which is by K higher than a water level 18 at the circumferential wall of an air chamber 10 in such a way that its grade is downward to the air chamber 10, and it is connected to a differential pressure detector 16. The detector 16 measures the differential pressure between a negative pressure inside the air chamber 10 and atmospheric pressure. A microscopic-pressure supply device 17 is connected to the air intake side of the detector 16, and the air whose pressure is sufficiently lower than the detected differential pressure is supplied so as to prevent moisture in the air chamber 10 from flowing backward and from penetrating into the detector 16.  When an object 1 to be detected does not exist, the detector 16 keeps a zero potential even when compressed air is discharged from an air discharge pipe 11. When the tip of the object 1 to be detected is situated just above the discharge pipe 11, the pressure of the detector 16 is dropped suddenly. As a result, it is possible to detect that the tip of the object 1 to be detected reaches the discharge pipe 11 on the basis of a point which exceeds a preset threshold value or on the basis of the degree of a pressure change.

Title: Coordinate conversion system for industrial robot
Inventor: SUZUKI MASAFUMI
IPC: B25J9/10
Filed: 1985-05-29
Abstract: PURPOSE:To convert effectively teaching program data for the execution of operation accompanied with weaving by providing a main conversion means for coordinate conversion and an auxiliary conversion means which corrects the change of the weaving amplitude due to coordinate conversion. CONSTITUTION:A work at the teaching time is different from an actual work 100', and a main conversion means 20 uses a conversion matrix M to convert position data P0, P1, P2, P3... belonging to teaching program data to position data P'0, P'11, P'22, P'3... by coordinate conversion. Data related to weaving auxiliary points out of converted data correspond to weaving temporary auxilia ry points P11 and P22. An auxiliary conversion means 30 subjects data indicating weaving temporary auxiliary points P11 and P22 to correcting conversion for the purpose of cancelling the change of the weaving amplitude accompanied with said coordinate conversion. Data of original weaving auxiliary points P1 and P2 are referred besides original weaving temporary auxiliary points. As the result, the length of the vector indicating the weaving auxiliary point P1 or P'1 coincides with the weaving amplitude accurately.

Title: Scanning electron microscope
Inventor: KOIKE KAZUYUKI
IPC: H01J37/22
Filed: 1995-05-12
Abstract: PURPOSE: To significantly enhance spatial resolution by removing contribution to image formation of a secondary electron generated by a scattered electron. CONSTITUTION: A secondary electron 6 emitted from a sample 2 is collected by a secondary electron collecting electrode 9, and is introduced to a secondary electron detector 12 through a spherical surface deflecting system 10 and an electrostatic lens 11. The detector 12 outputs a single electron pulse having a width of about 0.1psec per a detected single secondary electron. An amplifier 13 amplifies this, and transmits it to an image signal processing circuit 15 through a gate circuit 14.  An electron pulse obtained by a scattered electron 3 sprung into a microchannel plate 7 is amplified by an amplifier 16, and is inputted to a gate control circuit 17, and is impressed on the circuit 14 as a gate closing signal after a pulse width is expanded, and it is closed during a pulse width expanded from the arrival of the electron pulse from the plate 7, and a secondary electron 4 signal generated by the electron 3 is prevented from being transmitted to the circuit 15. Therefore, contribution to image formation of the secondary electron generated in a wider area than a beam diameter of a probe electron beam by the scattered electron can be removed.

Abstract: PURPOSE:To control the actual temperature so as to follow to the previously set temperature pattern, and to realize the good responsiveness and the removal of overshooting, by automatically adjusting the rate of heat radiation from the furnace against the amount and kind of the material to be heat treated and the outside temperature. CONSTITUTION:When the temperature of the furnace 11 is lower than the warmth keeping temperature and the tracking command from the condition discriminating circuit 9 is put off, the tracking controller 4 executes ordinary PID control action, and the temperature is raised following to the heat-up curve similar to the curve being set in the program setter 5. In the meantime, the arithmetic circuit 6 detects and operates the flow rate of fuel at every furnace temperature depending on outputs of the furnace temperature detector 7 and the flow rate detector 2; on the other hand, the arithmetic circuit 6 takes in the outside temperature from the output of the outside temperature detector 8, and operates the flow rate of fuel necessary to keep warmth at the warmth keeping temperature. When the furnace temperature rises up and the tracking command from the circuit 9 is put on, the controller 4 inputs the flow rate of fuel to keep warmth as the aim flow rate into the flow rate controller 1. As a result, the flow rate of fuel can be controlled to a specified value.
