IPC: H02H7/122
Filed: 1989-06-08
Abstract: PURPOSE: To prevent an overcurrent state in a power transistor by exhibiting the level of a current flowing into a MOSFET since a voltage generated between a drain electrode and an earth is proportional to the current flowing into the MOSFET at the time of the conduction of the MOSFET. CONSTITUTION: A MOSFET Q1 is alternately turned on and off by a signal VG at a frequency determined by the frequency of the signal during normal operation. The first terminal of the primary winding T1a of a chopper transformer T1 is connected to the drain electrode of the transistor Q1 , and the second terminal is connected to a DC input voltage +B. The voltage of the drain electrode is a voltage which is generated between both terminals of an on resistor, and the level of the first part of a signal is changed in proportion to the voltage of the drain electrode while the MOSFET Q1 is turned on to exhibit a current flowing through a transistor.

Abstract: PURPOSE:To control the light direction and improve the illumination efficiency by providing a light control part, which consist of nine prisms in a group, corresponding to each light emitting diode. CONSTITUTION:A light control part 43, which improve the visibility of a stop lamp from rear direction of a car body by leading a light emitted from a corresponded light emitting diode 19 to rear direction of the car body, consists of nine prisms 45A-45I in a group having the rough same size squares and arranged longitudinally and laterally in three lines and three pieces per each line. The center of a prism 45E positioned in the central part roughly coincides with the center of the correspond light emitting diode 19. The light control part provided on the internal surface of a front lens leads a light emitted from a correspond light emitting diodes, to the predetermined direction by reflecting it and reduces a light quantity which head other direction so as to be a loss. The visibility can be thus extremely improved without increasing a number of parts because of the light control part provided in the front lens itself.

Title: Picture reading and reproducing method
Inventor: TAMURA YASUYUKI
IPC: H04N1/04
Filed: 1981-09-18
Abstract: PURPOSE:To improve an error in reading an edge part of a picture by reproducing an intermediate level part in a specific color. CONSTITUTION:A CCD30 outputs a picture signal VOUT which has a potential corresponding to the lightness of a read picture every time it reads a picture element. This signal is applied to one-side terminals of comparators 32 and 33 in parallel. When the voltage of the applied signal VOUT is lower than a reference voltage V2, the comparators 32 and 33 both output 1, and consequently while a signal VR as a red signal is 0, a signal VB as a black signal is 1. When the voltage of the applied signal VOUT is higher than a reference voltage V1, the comparators 32 and 33 both output 0, and consequently the signals VR and VB are both 0. When the voltage of the applied signa VOUT is between the reference voltages V1 and V2, the output of the comparator 32 is 1 and the output of the comparator 33 is 0. Consequently, the signal VR is 1 and the signal VB is 0.

The part 12 estimates the light source by means of algorism such as simple averaging or cutting out a part estimated as white from the screen and averaging, and outputs a primary light source estimation result S1. The part 13 outputs a GWA discrimination signal J by judging from the features of the distribution of inputted image data. A general discrimination part 14 receives the result S1 and the signal J from the part 12 and outputs a secondary light source estimation result S2 to a light source estimation result retention part 15, and the part 15 otuputs a final light source estimation result Sf. Thus, whether or not the GWA stands up can be discriminated, and the light source can be definitely estimated.

At the same time, the light image of the relay optical system axis A2 is polarized at an acute angle by a 1st deflection angle prism 20A so that the angle to a horizontal surface is a downward angle beta deg. of deflection. The light beam whose optical path is extended by the relay optical system is deflected by a 2nd deflection angle prism 23 at an acute angle to the perpendicular direction and reaches an ocular 12, so that the light beam can be observed. At this time, the optical axis deflection point of the 2nd deflection angle prism 23 is lower by height B than a 1st optical axis polarization point, so the eye point or the ocular 12 can securely be made low.
