Title: System of controlling steering of motormanless travelling car
Inventor: IIDA KATSUHIRO
IPC: B65G35/00
Filed: 1977-09-12
Abstract: PURPOSE: To compensate steering delay in case of backing, by using the function of forward turning, which is shifted at a fixed distance in the positive or negative direction of a distance axle of the function, as the function of backing turning.  
     CONSTITUTION: A distance detector 2 detects travelling distance when a motormanless travelling car turns, and applies the output to a counter 3. A fixed function is programmed to a function generator 5 for backing turning, and the generator 5 puts out signals indicating steering angles at that time in response to position signals from the counter 3. When backing turning, a switch S 2  is in ON, signals from the function generator 5 are applied to a line L, and the steering angles of steering is controlled in response to signals introduced to the line L

CONSTITUTION:A pinch roll 4 and a poling reel 6 are rotated respectively at the peripheral speed synchronous to the material speed of a rolled material 1, and the rolled material 1 is formed into a coil by the poling reel 6. A coil rear end involute control device, upon reaching the time when the rear end 15 of the material 1 satisfies the condition of the rear end involute length Ls= Lo-L, outputs the output 27 of the arithmetic unit 26 of the rear end control device to a poling reel drive unit 28 and increases the engine speed of a poling reel driving motor 11 by the specified quantity so as to increase the peripheral speed of the poling reel 6. The material 1 between the roll 4 and the reel 6 is then pulled forcibly, so that the diameter of a coil 7 formed of the material 1 in this part becomes smaller than that of the coil formed previously.

Filed: 1995-05-09
Abstract: PURPOSE: To accurately measure fuel oil C, crude oil, etc., by maintaining a liquefying tank, measurement chamber, and the transferring route of a liquid to be measured at constant temperatures, respectively. CONSTITUTION: An object to be measured, such as the fuel oil C, crude oil, etc., liquefied in a liquefying tank 22 is carried to a measurement chamber 24 by means of a pump 23. In the measurement chamber 24, the object to be measured is analyzed for components by irradiating the object with near infrared to infrared rays while the object is passed through a cell and measuring the variation of the absorbency of the rays. After measurement, the object is sent to a boiler, etc. Here, a flow rate controller 21 raises the temperature in a thermostatic chamber 20 to a prescribed value by controlling the flow rate of not water or steam. The chamber 20 maintains the liquefying tank 22, measurement chamber 24, and the transferring route of the object from the tank 22 to the chamber 24 at constant temperatures so as to prevent the solidification of the fuel oil C, crude oil, etc.  Therefore, the fuel oil C, crude oil, etc., can be measured with accuracy, because the high-boiling-point substances do not solidify during measurement.

Title: Suction air intake duct
Inventor: URUSHIBARA HIROSHI
IPC: F02M35/16
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent foreign matter such as dusts from piling up inside an air intake port in a suction air intake duct vertically provided at a side of a vehicle between a cab and a load-carrying platform by providing air intake ports on a surface facing a rearward of the vehicle and on a surface facing to a space between the cab and the load-carrying platform, respectively. SOLUTION: When an external air 12 is suctioned to an engine through a suction air intake duct 1, the air 12 is suctioned from a space between the duct 1 and a hood 7 at a rearward of a rear panel 3 of the cab 2 by a first air intake port 5 of the duct 1 and suctioned from a space between the cab 2 and the hood 7 by a second air intake port 20. According to the structure, since the second air intake port 20 functions as a by-path even if the first air intake port 5 is blocked by the hood 7 covering the load-carrying platform, it can be prevented that an intake efficiency of the engine is decreased. Further, since the respective air intake ports 5, 20 do not suction an air from a side surface 9 facing to outside the vehicle, foreign matter can be prevented from piling up.

Title: Speed-converting device for reaping and conveying
Inventor: SANESHIGE HIDEO
IPC: A01D61/00
Filed: 1989-04-30
Abstract: PURPOSE:To efficiently carry out harvest operating by providing two kinds of transmission ratios for running speed and reaping-driving speed, setting two kinds of mutually crossing functions indicating the ratio of an increase in reaping-driving speed per an increase in running speed, and enabling to select two ways of the transmission ratio. CONSTITUTION:In the output of low speed gear 35 in which running speed is >=1.0m/sec, reaping-driving speed is too fast and exerts bad influence upon a material to be harvested and noise from reaping working machine is enormous. Therefore, by switching the gear to high speed gear 23, a quiet reaping operation is made possible without hindering a material to be harvested even in high speed of >=1.0m/sec. When grain-straw kept in fallen state is reaped, it is necessary to run at low speed and make reaping-driving speed fast. Therefore, sure reaping operation can be carried out by outputting from high speed gear 33 capable of running at low speed and being fast in reaping-driving speed. Further, since function of number of output revolution of reaping output shaft 38 by high speed gear 33 and low speed gear 35 to running speed crosses at running speed near 0.6m/sec which is normally frequently used, even if changeover is mistaken, the influence is small.

CONSTITUTION:An image pickup picture signal of the image pickup region obtained by an ITV camera 1 is led to a non-inverting input of a comparator 3 via a camera control circuit 2. On the other hand, correction information from a correction value generating circuit 4 is fed to an inverting input of the comparator 3. In driving the ITV camera 1 to apply image pickup scanning to the image pickup region, a read address is generated respectively from an X direction address counter 5 and a Y direction address counter 6 and the correction information corresponding to the image pickup device 1 is read from a correction memory 4a. After the correction information is converted into an analog signal by a D/A converter 4b and fed to a comparator 3 as a binary coding threshold level and the image pickup signal from the ITV camera 1 using the correction information as the threshold level is binary-coded.
