Title: Optical disk drive device
Inventor: KIGUCHI HIROYUKI
IPC: G11B7/085
Filed: 1993-06-30
Abstract: PURPOSE:To make cancellation possible even when the characteristic of a lens supporting member is changed by a temperature by smoothing operations by calculating the transited amount of the nominal position of an objective lens with a lens hold system, previously storing this amount and applying a moved amount for canceling this displaced amount to a driver. CONSTITUTION:A light beam from a light source 5 of an optical pickup 1 is made incident through a beam splitter 8 and an objective lens 2 on an optical disk 3, and reflected light is inputted through the lens 2 and the splitter 8 to a photodetector 9 of a tracking system 4. At the photodetector 9, a difference signal is calculated by applying the output signal to an error detector 10, and a tracking error signal is calculated by inputting this difference signal to a servo circuit 11. This error signal is inputted through an adder 12 to a driver 13, and this is defined as a drive signal for driving an actuator 6 of the optical pickup 1. On the other hand, at a lens hold system 7, the tracking direction position of the actuator 6 is detected by a sensor 14, and a lens correct signal is outputted from a servo circuit 16.

Title: Dust inspection system
Inventor: TAKAHASHI HITOSHI
IPC: G03F1/84
Filed: 1988-07-22
Abstract: PURPOSE:To put an automatic inspection system to practial use by projecting light on a reticle, photodetecting its transmitted light by a photoelectric converting element and obtaining the photoelectric conversion output of the reticle pattern, and comparing its binary-coded output with digital data. CONSTITUTION:The pattern of the reticle 10 is filed in a memory 20 while converted into binary data so that the glass (transparent) part is 1 and the chromium (opaque) part is 0. then the reticle 10 is set and irradiated with the light, whose transmitted light is guided to a pinhole detector 31 on a stage 20 by an optical system 32. The detector 31 is moved in an (x)- and a (y)- direction by a stage 30 to generate the (x)- and (y)-directional scanning outputs of the reticle 10. Therefore, when no dust sticks on the reticle 10, the output of the detector 31 is equal to the pattern data on the reticle 10 which is stored in the memory 20, but if dust sticks, the output is not equal to the pattern data. Consequently, whether dust sticks or not is known.

Further, primary air is supplied into a vaporization cylinder 2 where the air is mixed with the vaporized fuel to become a gas mixture passes through a burner head 12 to make a combuston flame 13. The vaporization surface 15 of the vaporization cylinder 8 is formed of the porous anodeoxidized film carrying alkali and the temperature of the vaporization surface 15 is made higher than the film boiling region temperature of the liquid fuel to thereby vaporize the liquid fuel. As a resut, the weight of tar generating on the vaporization surface 15 becomes extremely small.
