IPC: G06T1/00
Filed: 1987-02-25
Abstract: PURPOSE:To obtain an image processing device capable of coping with even the change of the material, the thickness, etc., of a work by providing an illuminating power supply device with the automatic dimming function. CONSTITUTION:The video signal picked up by a CCD camera 1 is taken into a peak holding circuit 23 through an amplifier 17 of the image processing device 7, a video amplifier 19, and an A/D converter 21. Further, a peak hold value P from the peak holding circuit 23 is taken into a CPU 25. If this value P is lower than a lower limit value L, such procedure is performed as the voltage of illuminating power is increased by an illuminating power supply circuit 37, that is, the illumination is increased. If the value P is not smaller than the value L, it is discriminated whether the peak hold value P is larger than an upper limit value U or not. If the value P is larger than the value U, such procedure is performed as the voltage of illuminating power is reduced by the illuminating power supply circuit 37, that is, the illumination is reduced.

Title: Air purifying method for automobile and device therefor
Inventor: ANDO MASAO
IPC: B01D53/86
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To efficiently remove NO in air by irradiating an adsorbent essentially comprising activated carbon which carries a photocatalyst so that NO in air is oxidized to produce NOx by the the photocatalyst and the NOx is adsorbed by the adsorbent. SOLUTION: The adsorbent 30 is produced by depositing a photocatalyst comprising TiO2 which oxidizes NO to produce NOx and a Pd catalyst which oxidizes CO to produce CO2 on an activated carbon fiber 34 which adsorbs NOx. When the adsorbent 30 is irradiated with UV rays from a discharge lamp 58 having no electrode, NO in air is oxidized to produce NOx, which is then adsorbed by the adsorbent 30. Thus, NO in air is removed to purify the air. Then the purified air is introduced into a car. Therefore, harmful gas as well as fume from cigarettes, dust, etc., can be removed by the on-vehicle air purifying device.
