Title: Laser diode on/off signal generator
Inventor: YAMAGUCHI ATSUHIKO
IPC: B41J2/44
Filed: 1988-12-01
Abstract: PURPOSE:To enable one white dot among black dots to be printed sharp by providing an output circuit for outputting an ON/OFF signal to a laser diode which becomes a low level when both data outputted from a synchronous control circuit and a signal outputted from a variable timer are low levels. CONSTITUTION:According to an ON/OFF signal-LD, a printing is conducted with black in a low level and white in a high level. The black part of a low level is reduced in width in comparison with a low level of video data-VDA. On the contrary, the white part of high level is extended in width in comparison with a high level of the video data-VDA. Therefore, a laser diode is turned ON to output a laser beam when the ON/OFF signal-LD is a low level. If the laser beam is increased in diameter more or less, a part to be printed white is positively ensured because an ON time of the laser diode is reduced. Therefore, even a white dot among black dots can be printed sharp.

IPC: G01L3/10
Filed: 1988-12-01
Abstract: PURPOSE:To sharply improve the hysteresis characteristics of detecting data by forming parts which are adjacent to magnetic anisotropic sections and increased in magnetic reluctance to have depths deeper than a skin depth. CONSTITUTION:Parts 17 where magnetic reluctance is increased are formed to the depth deeper than a skin depth, namely, the depth of the part where magnetic fluxes 16 pass through of the surface layer of a shaft 11 together with magnetic anisotropic sections 12 and 13. When an AC of about 10kHz and 100mApp is used as an excitation current, the skin depth becomes about 0.1-0.2mm and the magnetic fluxes 16 do not penetrate deeper than the depth. Therefore, when, for example, the parts 17 where the magnetic reluctance is increased in the axial direction are formed by means of working grooves, the parts 17 can be formed sufficiently when grooves having a depth of about 1mm are formed irrespective of the size of the diameter of the shaft. In addition, the appropriate arranging pitch of the working grooves is about 1mm and about 5mm is suitable for the width of the parts 17 increased in magnetic reluctance in the axial direction.

Abstract: PURPOSE:To detect ground car speed with high accuracy and improve reliability of systems operated using the ground car speed by obtaining the difference of car speeds between the first and the second car speeds detected with a wheel using type car speed detector and a doppler type car speed detector. CONSTITUTION:The first car speed detected with a wheel using type car speed detector 1 is affected by the slip of wheel in the front and back direction and so the shift from the actual speed increases with the slip.

Then, a car speed difference determination means 3 obtains the car speed difference between the first car speed and the second bar speed in the state the first car speed agrees with the actual car speed with good accuracy. A ground car speed determination means 4 determines a ground car speed based on the second car speed and the car speed difference in the state the first car speed does not well agree with the actual car speed. By this, the first car speed is efficiently utilized to detect ground car speed with high accuracy.
