Title: Ground improver
Inventor: OGIWARA ATSUO
IPC: E02D3/12
Filed: 1980-06-11
Abstract: PURPOSE: To prevent the falling of a ground improver by lowering its gravity center by a method in which a rotary table is attached to a base machine, and a keeley bar is turned at a position near the ground's surface and also driven downwards by pressing through a pulley mechanism.  
     CONSTITUTION: A rotary table 12 is attached to a self-running base machine 6 by a fixing means 13 so as to allow a kelley bar 3 to turn. Also, a stirring balde 1 is provided to the lower end of the kelley bar 3 as usual. The kelley bar 3 piercing the rotary table 12 is hung on a hanging mechanism 33 from the tip of a boom 11 through a swivel joint 32 at its upper end, and is pressed down through a pulley mechanism by coiling up a wire 38 by a winch 37.

Title: Magnetic recording method
Inventor: MORIMOTO TAKEKATSU
IPC: H04N5/7826
Filed: 1979-06-19
Abstract: PURPOSE: To increase easily the rewinding accuracy of the tape, by securing the inversion for a fixed time for the capstan motor and thus giving the inversion to the tape.  
     CONSTITUTION: Capstan motor 12 usually turns clockwise, and the sag is easily caused at the left part of belt 16 due to the relation between the rotational direction and the load. Owing to this sag, idler 6 is detached from supply reel turntable 4, and then idler 9 is pressed to take-up reel turntable 5 to give the clockwise turn to take-up reel 2. Here if the pause button is pressed in timing A, motor 12 is reversed for t 1 sec. And pinch roller 20 is released after the t 1 sec. As a result, the tape is reversed by that amount by capstan 19 to cause the sag at the right part of belt 16. Thus idler 9 is detached from turntable 5 and then pressed to turntable 4 to give the counterclockwise turn to reel 1, and the tape is taken up to reel 1 by the same amount at the turn. When the pause button is released, pinch solenoid 29 operates to press capstan 19 to roller 20 and thus secure the normal running of the tape. As a result, the t 2 sec editing mode is secured to give the normal mode after the t 2  sec. Thus the joint part is improved.

IPC: G01L1/00
Filed: 1990-03-27
Abstract: PURPOSE:To make exact inspection in a short period of time by disposing a property measuring means in the downstream position of a surface treating means with respect to a material transporting direction, disposing a screening means in the further downstream position of the property measuring means and operating the screening means in accordance with the result of the measurement by this property measuring means. CONSTITUTION:A position sensitive proportional counter tube 11 can turn parallel with the turning surface of an X-ray generator 10 and has a core wire 13 extending along the turning direction thereof. This counter tube receives the X-rays diffracted by the material in its core wire 13 and outputs the intensity of the X-rays as an electric signal. A multichannel analyzer 12 is inputted with the electric signal outputted from the position sensitive proportional counter tube 11 and detects the X-ray intensity at every channel corresponding to the microsegments of the core wire 13. The exact results of the inspection are known in this way. The easy dealing with the transporting speed of the material is possible even if this speed is high.

Title: Device for detecting amount of intake air flow in internal combustion engine
Inventor: MIZUNO KAZUYOSHI
IPC: F02D41/18
Filed: 1981-05-25
Abstract: PURPOSE:To perform highly accurate intake air flow flow detection, by selecting the output of a corresponding potentiometer in response to the amount of the intake air flow, and decreasing the relative errors at the time of air flow detection and the relative resolution of A/D conversion. CONSTITUTION:When the intake air flow is judged 34 to be large in response to a rotary speed 30 and a throttle valve opening opening degree 32 which can equivallently represent the intake air flow, the output voltage on the side of a slider 20 is selected. When the intake air flow is small, the output on the side of a slider 18 is selected. Said voltage is converted 28 from the analog values to the digital values, and the final detected value of the intake air flow is obtained. The sliders 18 and 20 have different full scale ratios with respect to a specified angular displacement of a measuring plate 10, and generate the voltages having the different voltage values. Therefore, the relative differences of the potentiometer 28 with respect to the same intake air flow have the different values. By selecting the slider output voltage having the smaller relative error, the highly accurate measurement of the intake air flow can be performed.

Title: Travel course matching method of navigation device
Inventor: YOSHIDA MOTOMASA
IPC: G08G1/0969
Filed: 1992-02-28
Abstract: PURPOSE:To exactly correct an error of recognizing that a travel course is not a scheduled travel course by calculating the detected position of a vehicle from a scheduled position, matching the detected position with the scheduled position when the deviation is less than a threshold value, and continuing the calculation of the vehicle travel course from the position. CONSTITUTION:When a course change of the vehicle is detected, the error (d) between the course change scheduled point O and an estimated course change point O' is calculated first. It is decided whether or not the error (d) is less than the threshold value D. The threshold value D is varied with the value of a straight travel distance L. Namely, two threshold values D are calculated from equations according to whether the distance L reaches a specific distance K. Namely, D1=45X0.035XK(m) when L is less than K and D2=45X0.05XL(m) when L is larger than the K. Then the error (d) is compared with the D1 or D2 according to the travel distance L and when the error is less than the D1 or D2, the point O' is matched with the point O; and the calculation of a subsequent vehicle travel course is carried on from the point.

Abstract: PURPOSE:To suck efficiently the gas in a cavity and to form a defectless casting by attaching a device for sucking and ejecting gas and a sensor for detecting a molten metal to dies in the position where a misrun is liable to arise and providing means for controlling both in association. CONSTITUTION:The device 10 for sucking and ejecting the gas constituting of an air vent 11, etc. is attached to the die such as a movable die 4 facing the position where the misrun is liable to arise.

The molten metal is thus filled into the cavity 8 without incorporating the gas therein. The signal for the presence of the molten metal is transmitted to the device 18 when the thermocouple 26 confirms the presence of the molten metal. The device 18 stops the suction by closing the valve 15. As a result, the molten metal is prevented from entering the inside of the air vent 11.
