Title: Range finding type matter detection apparatus
Inventor: AZUMA NAOYA
IPC: G01S15/04
Filed: 1985-01-25
Abstract: PURPOSE:To enable the detection of matter over a wide range, by forming a detection area having a boundary surface almost parallel to the mount surface of matter sensors and not having a dead angle by a relatively reduced number of matter sensors by changing over two detection modes. CONSTITUTION:A first mode, wherein the reflected wave of the ultrasonic wave sent out of the transmitter of each matter sensor 1 in received by the receiver of the same matter sensor 1, and a second mode, wherein the reflected wave of the ultrasonic wave emitted from one of a pair of adjacent matter sensors is received by the receiver of the other matter sensor 1, are alternately changed over. In the first mode, a dead angle 4 is formed to a detection area 2a in the space between the mount surface 3 of the matter sensors 1 and the flat surface spaced apart by a predetermined distance L from said mount surface 3. In the second mode, the detection area 2b comes to a shape near to an oval surface having both matter sensors 1 as focuses and no dead angle 4 is formed at the central part between both matter sensors 1. When this oval shape is set to a proper size, the dead angle formed when detected in the first mode can be covered.

IPC: G16H10/60
Filed: 1991-01-08
Abstract: PURPOSE:To increase the speed of processing a T1 image by reducing the cycle number of search operation for an argument upon conversion into the T1 image by using a conversion table indicating the relationship between the signal intensity and a longitudinal magnetization relaxing time. CONSTITUTION:The relationship between an argument R and a signal intensity ratio T1 is approximated to a straight line for every subsection so that it is approximated to a polygonal line in total with the use of a conversion table on which values of correspondence between signal intensity ratios R and longitudinal magnetization relaxing times T1 of MRI images are recorded. Upper and lower limit values, an inclination and an intercept of a straight line in every section are stored as a section table. The value of the signal intensity ratio R of an R-image inputted upon conversion is compared with the upper and/or lower limit values on the table so as to obtain an applicable section with which the search is made successively for a nearest one.

Inventor: MATSUMOTO YASUHEI
IPC: B60K17/346
Filed: 1986-01-23
Abstract: PURPOSE:To improve performance of a differential lock by constituting to transmit a 1st and a 2nd output components of a planetary gear respectively to front and rear wheels and arranging a viscous coupling and a set of clutch in series, thereby obtaining two kinds of 4-wheel drive (4WD) modes. CONSTITUTION:When a select lever 48 is thrown in a direct connection 4WD position, an engagement clutch 45 changes over to the direct connection side and a sun gear 31 and a ring gear 32 are united in one. Accordingly, the drive mode becomes the front and rear wheel direct connection 4WD. When the select lever 48 is thrown in a 4WD position with CD&VC on the other hand, the engagement clutch 45 changes over to a viscous coupling side and drive power is distributed via a planetary gear 30 to both front and rear wheels, making the drive mode a 4WD with center differential. Since this makes it possible to optionally set the performance of a differential lock due to the torque characteristics of the viscous coupling, it is possible to drive with each even on rough roads.

Title: Automatic gap adjuster for brake
Inventor: KAWASE KAZUO
IPC: F16D65/54
Filed: 1979-02-09
Abstract: PURPOSE: To enable assured operation with a simple structure by a method wherein a rod having a tapered surface to get into close contact with the inside peripheral surface of a tapered central hole of a ring member fitted in a cylindrical portion is inserted in the hole, and a gap is formed between a flange surface formed at one end of the rod and the end face of the ring member.  
     CONSTITUTION: As wear amount of linings of brake shoes 4 increases, the extension amount of a sliding portion 1a of a strut increases. As a result, the end face of a ring member 6 comes into contact with that of a flange portion 2b, and the member 6 moves leftward inside the inside peripheral surface 5a of a cylindrical portion as the portion 1a extends. Therefore, when the right and left brake shoes 4 area returned to their original positions after release of braking, the inside peripheral surface of a central hole 6a comes into close contact with the outside peripheral surface of a rod end portion 2a before the portion 1a contracts to its original length, so that the member 6 cuts in between the surface 5a and the outside peripheral surface of the portion 2a just like a wedge to immobilize the portion 1a, thereby adjusting the gap by the reduced contraction amount.

Title: Electromagnetic flow meter
Inventor: UENO KAZUO
IPC: G01F1/58
Filed: 1979-02-08
Abstract: PURPOSE: To realize a flow meter which features the reduced effect of the zero-point fluctuation due to the electrochemical function as well as the reduced amount of power consumption, by applying the pulse which features the small pulse duration with the polarities changing alternately to the exciting coil of the magnetic circuit.  
     CONSTITUTION: A pair of electrodes 2a and 2b are provided in tube path 1 of the fluid, and exciting coils 5a and 5b are mounted to magnetic poles 4a and 4b to give excitation to magnetic circuit 4. The pulse of the small duration featuring the polarities changing alternately is applied to coils 5a and 5b via exciting device 6 and controller 7. Thus nearly the fixed residual magnetic flux is caused following the magnetic flux changing in the form of a peak between poles 4a and 4b. In that case, the voltage occurring between electrodes 2a and 2b is proportional to the product of the magnetic flux and the flowing speed within path 1. And then the sampling is given to the output between poles 2a and 2b along with the time averaging by avoiding the period during which the exciting pulse is applied with large voltage fluctuation. As a result, the zero-point fluctuation due to the electrochemical function is eliminated, thus ensuring the flow amount measurement with the reduced amount of power consumption.
