Title: Data transmission equipment
Inventor: KATSUMATA YOSHINOBU
IPC: H03M5/12
Filed: 1989-07-05
Abstract: PURPOSE:To send a transmission output signal represented by the Manchester code corresponding to the code polarity of a data signal accurately by generating a transmission output signal so as to be coincident with the code polarity of the data signal at all times independently of each rise timing of a data signal and a clock signal. CONSTITUTION:When a data signal representing by an NRZ code is inputted to an external input terminal 16, a clock signal taking a half the code polarity inversion unit time T of the data signal as one period is inputted to an external input terminal 13. The conversion timing from a data signal into a synchronizing data signal executed by a synchronizing data signal generating circuit 20 is retarded from the inversion timing of code polarity of the data signal by nearly one period of the clock signal, that is, a half the code polarity inversion unit time of the data signal. Thus, the conversion from the data signal into the synchronizing data signal is implemented in the timing of the code polarity of the data signal is stable.

Abstract: PURPOSE: To make possible the correction of aberrations by arraying three plane lenses by aligning their optical axis, and determining the style of their disposition in a manner as to permit formation of an erecting unmagnified real image as a whole thereby forming one unit of a plane lens system.  
     CONSTITUTION: The same plane lenses 11, 12, 13 of a focal length f 1  are disposed on the same optical axis 0, and the style of their disposition is so determined that the distance between the front side main point H 12  of the plane lens 12, and the rear side main point H 11  of the plane lens 11 is made approximately 2f 1 . The thicknesses of the individual plane lenses are determined smaller than 1/4 the space period of the sine curve of the transmitted light in these. If an object plane PO is determined in the position of a distance 2f 1  forward of the front side main point H 11  of the plane lens 11 and an image plane QI is set in the position of a distance 2f 1  backward of the rear side main point H 12 , of the plane lens 13, the erecting unmagnified real image of the object on the object surface is formed by this plane lens system 100. In this case, the correction of aberrations is made possible by finely adjusting mutually the distances between the plane lenses 11, 12, 13 in the plane lens system 100.

Title: Electrical power steering device
Inventor: NAITO HIROSHI
IPC: B62D5/04
Filed: 1986-07-22
Abstract: PURPOSE:To prevent the reverse assist, by stopping a motor when the result of comparison between a signal fed from a first detector for detecting the axial displacement of a slider and a signal fed from a second detector for detecting the rotary torque of a steering wheel is not equal to a setting level. CONSTITUTION:Axial displacement of a slider is detected by a first detector or a distorsion gauge 22 while rotary torque of a steering wheel is detected by a second detector or a distorsion gauge 33. When abnormality occurs in the first or second detector because of some reason, signals are fed from the distorsion gauges 22, 33 through a controller 25 to a decision circuit so as to decide that the electrical signals from said gauges 22, 33 have different levels. Consequently, an L-level electrical signal is applied onto the input terminal of a relay logic so as to turn off a main relay and to stop a motor DM thus preventing the automatic steering.
