Title: Power steering device
Inventor: KOMAMURA SEIJI
IPC: B62D5/06
Filed: 1981-12-21
Abstract: PURPOSE:To prevent a steering force from varying, by a method wherein a steering force T and a steering angle theta of a steering wheel are detected, and a power shifting force is regulated so that the change rate dT/dtheta becomes constant. CONSTITUTION:An input shaft 2 is fitted with a steering force 5 and a steering angle sensor 6 to detect the steering force T and the steering angle theta which are transmitted to the shaft 2. Values detected by the sensors 5, 6 are sent to a controlling circuit 8 together with a signal fed from a vehicle speed sensor 7. At a vehicle speed 7 not higher than a predetermined value, the circuit 8 calculates dT/dtheta from the steering force T and the steering angle theta, and outputs a driving signal to a power shift correcting means 10 so that the change rate (dT/dtheta) becomes constant. Namely, an assisting hydraulic pressure is increased at the time of increasing the steering force when dT/dtheta is positive, and the pressure is reduced or cut off at the time of lowering the steering force when dT/dtheta is negative, whereby the steering force is prevented from varying.

Title: Ultrasonic car height measuring apparatus
Inventor: TANAKA HARUTO
IPC: G01B17/00
Filed: 1982-11-25
Abstract: PURPOSE:To make it possible to always and accurately measure a car height without being affected by the state of a road surface, by correcting a measured value on the basis of the rising characteristics of a receiving wave returned while reflected from the road surface. CONSTITUTION:The ultrasonic pulse transmitted from a transmitter 3 is reflected at a road surface 4 and the reflected pulse is received by a receiver 5. This receiving output is respectively applied to a wave form shaping circuit 8 and a wave form rising circuit 16 through an amplifier 6 and a rectifier circuit 7. In this case, when the receiving wave becomes weak by the state of the road surface, the rising of the output wave form of the rectifier circuit 7 becomes gentle to generate a measuring error. Hereupon, an analytical circuit 16 receives the output of the rectifier circuit 7 to measure the rising characteristics of the receiving wave ans a correction value N is fabricated based on this rising characteristics. Subsequently, this correction value and the output of the wave form shaping circuit 8 are inputted to a micro CPU15 for operating car height. By this method, the car height can always accurately measured without being affected by the state of the road surface.

Abstract: PROBLEM TO BE SOLVED: To suppress the reduction of a collation ratio by means of a fingertip fingerprint pattern in a image collation method by discriminating the coincidence of a fingerprint pattern for collation and a fingerprint pattern for reference of the basis of the information of collation between both the fingerprint patterns. SOLUTION: The fingerprint image of a finger placed on the input end face of a finger optical plate(FOP) 3 is acquired by a CCD camera 4, digitized as a collation fingerprint image and a reference fingerprint image and stored in a frame memory 5. In order to reduce an adverse influence to be exerted upon collation by a fingertip part on the basis of image signals stored in the memory 5, a digital signal processor(DSP) 11 weighs a fixed area including the fingertip part less than '1', performs operation such as high speed Fourier transformation and finds the signal of correlation between a previously stored image signal for reference and the image signal for collation at the time of figure collation. On the basis of the correlation signal found by the DSP 11, a control CPU 8 discriminates whether the collated person is a registered person himself or not.
