Title: Absolute value circuit
Inventor: SATO HARUNORI
IPC: G06G7/25
Filed: 1986-11-19
Abstract: PURPOSE:To obtain an absolute value of a varying signal by supplying each common mode output current of a differential amplifier to a current mirror, respectively, applying those which have subtracted a prescribed current by each current mirror to a diode, respectively, and using its sum current as an output current. CONSTITUTION:When an input Vi is applied between each base of transistors Q1, Q2, each collector current I1, I2 flows. A current is inverted by each PNP current mirror Q3, Q4 and Q5, Q6, and with respect to each of them, a current I0 is subtracted, therefore, a current flowing to each diode becomes ¦i1¦, ¦i2¦. A current flowing through a resistance R3 goes to i0=¦i1¦+¦i2¦, and an (I-V)- converted voltage V0 is obtained. In such a way, after having allowed a current to pass through a circuit of a common mode (differential type), the current I0 of half of 2I0 of a current source 4 is subtracted, therefore, an absolute value circuit having no offset theoretically is obtained with high accuracy.

Abstract: PURPOSE:To correct and eliminate coma-aberration generated simultaneously with astigmatism, by providing a compensator and an optical detector arranged obliquely in a direction opposite to the optical axis of a laser beam being emitted from a light source at the rear side of a flat type beam splitter. CONSTITUTION:A beam of light emitted from the light source 11 is reflected on the surface of the flat type beam splitter 12 first, and is converged on an objective lens 14, and is focused on the information recording plane of an optical disk 13. Next, converged light reflected on the plane transmits the inside of the flat type beam splitter 12, and furthermore, passes through the inside of the compensator 15 and transmits to the rear plane, then arrives at the detecting part of the optical detector 16. And the coma-aberration generated due to transmission in the flat type beam splitter 12 is corrected by transmitting the compensator 15, and only the astigmatism appears on the beam of light arriving at the optical detector 16. Thereby, it is possible to clearly detect aberration between the information recording plane of the optical disk 13 and the objective lens 14 by using the astigmatism.

Title: Linear light source and its fixing method and light source device
Inventor: DOI ATSUHIRO
IPC: G03B27/54
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To efficiently absorb heat by making it possible to surely absorb the heat quantity from a resistor and preventing the transfer of heat energy to light emitting elements. SOLUTION: The light emitting elements 62, 63, 64 are arranged along one end on the short side on a substrate 59 and the resistor 90 is arranged at the other end on the short side. A heat sink 92 is stuck to the rear surface side of this substrate 59 and plays the role of absorbing the heat generated from the resistor 90 and releasing the heat. This heat sink is stuck only to the rear surface corresponding to the position where the resistor 90 is mounted. Namely, the heat sink is not stuck to the rear surface corresponding to the positions where the light emitting elements 62, 63, 64 are mounted. The reason thereof lies in that there is a large difference between the calorific value of the resistor 90 and the calorific value of the light emitting elements 62, 62, 64 and that the heat absorbed from the resistor 90 is released reversedly to the light emitting elements 62, 63, 64.

CONSTITUTION:When the 1st electrode 2 and a body 5 to be charged are short- circuited and the AC voltage is applied between the 1st electrode 2 and the 2nd electrode 3, a charging current IC flows through an ammeter 10. Namely, a positive voltage based upon the 1st electrode 2 is applied to the 2nd electrode 3 within a range of 0<t<t1 when a point A is regarded as a reference point, and an electric field is produced between the grounded object body 5 and the 2nd electrode 3 in such a direction that positive ions are charged, thereby sticking the positive ions on the surface of the objective body 5. In a range of t1<t<t2, on the other hand, a negative voltage based upon the 1st electrode 2 is applied to the 2nd electrode 3 and an electric field is established between the object body 5 and the 2nd electrode 3 in such a direction that negative ions are charged, so the surface of the object body 5 is charged to the negative polarity and a negative current flows through the ammeter 10. Consequently, the need for a DC power source is eliminated and the cost of the power source is reduced greatly.
