Title: Lottery ticket
Inventor: MATSUDAIRA OSAHISA
IPC: B42D15/10
Filed: 1992-10-21
Abstract: PURPOSE:To provide a lottery ticket in which 'its lucky number' or 'blank' can be simply identified over the counter and yet an illegal act scarcely occurs. CONSTITUTION:A lottery ticket 1 comprises a mark formed on an infrared ray reflective base material of infrared ray absorption printing ink containing 20wt.% or more of Fe<2+> and/or Cu<2+> and phosphate series white crystal powder including phosphorus hemipentaoxide as a main ingredient. Since the powder has absorption for an infrared region but no absorption for a visible region, the mark 3 formed of the ink containing the powder is difficult to be visually confirmed, and can be mechanically read with the infrared ray in combination with the mark 3 and an infrared ray reflective base material.

Title: Optical head
Inventor: MORISHITA ICHIRO
IPC: G11B7/125
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical head capable of preventing substantial fluctuation in a light quantity applied to a recording medium when an objective lens is shifted. SOLUTION: A reception light output from a pin photodiode 4 is detected by a detection part 6 to be sent to a CPU 7. The CPU 7 detects the level of the reception light output, and controls a gain of an amplifier 6a based on the level. When the light quantity irradiated on a disk D is attenuated greatly, the light quantity can't be compensated only by gain control by the amplifier 6a. In such a case, a light emission switch part 10 is controlled by a light quantity control signal, and a light emission intensity from a semiconductor laser 1 is switched directly. By controlling the light emission intensity of the semiconductor laser 1, the sufficient light quantity is applied to the disk D always.
