Title: Optical head device
Inventor: TANIGUCHI NAOSATO
IPC: G11B7/1365
Filed: 1985-12-16
Abstract: PURPOSE:To make the device small and light and to reduce the cost by providing a diffraction grating structure that diffracts light passed through the first face and leads to a photodetector in the second face of a light splitter. CONSTITUTION:Light diffracted by an area 8 deviated from an optical axis is deflected to the direction of the arrow mark B. Accordingly, a focus error signal is obtained by differentiating the detected signals of light receiving sections 11 and 12. The division line between areas 9 and 10 of a diffraction grating structure 7 is provided in parallel to an information track on the information carrier 5. Light receiving sections 13 and 14 detect photoelectrically light intensity distribution in divided far field patterns of the information track, and a tracking error is obtained by differentiating the detected signals. The focus error signal and tracking error signal are fed back to a lens driving mechanism, not shown in the figure, and shifts an objective lens in the direction of optical axis and in the direction perpendicular to optical axis, and the focusing and tracking are executed.

IPC: G01N33/52
Filed: 1990-10-20
Abstract: PURPOSE:To enable analysis which is high in sensitivity, free from interference of interfering ions and excellent in ion selectivity and quickness by maintaining pH within a specific range when used in pH buffer. CONSTITUTION:A dry analysis element for analyzing iron ion comprises a detecting reagent layer 12 and a pre-processing layer 14 laminated on a light permeable support 10. The pre-processing layer 14 comprises a water penetrating layer and contains chelating agent which is specifically coordinated in Cu ions. The reagent layer 12 comprises a water penetrating layer and contains chelate reagent Nitro-PAPS excellent in detection sensitivity and cation compounds. A pH buffer is contained wherein pH is maintained in a range of 3.0 to 5.0 when used in either of the above layers or in other layers to prevent Zn ions from forming complex with the reagent Nitro-PAPS. The chelating agent and the pH buffer of the pre-processing layer 14 are used to eliminate interfering ions such as Cu ions and Zn ions respectively, and analysis is free from the ions while excellent ion selectivity can be obtained.

Inventor: OTOMO HIROAKI
IPC: G01B11/00
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce measurement error of a distance cased by a secondary reflection on an object. SOLUTION: A pair of light receiving means 2a and 2b are arranged in the plane symmetry to a plane including a light beam from a light emitting means 1. The light receiving means 2a and 2b are provided with light receiving elements 21a and 21b, and both the light receiving elements 21a and 21b are connected in parallel so that terminals whose increase/decrease of output signal values coincide with each other according to a distance to an object 4 are commonly connected. Thus, in the direction crossing a symmetrical face between both the light receiving means 2a and 2b, even if a calescence point by secondary reflection is generated in the object 4, an error component accompanying the secondary reflection is eliminated from the synthetic output of the light receiving elements 21a and 21b, and a distance can be accurately measured.

Abstract: PURPOSE:To shorten a rising time of transmission power by adding an additional signal rising and attenuated in a short time to a voltage difference between a reference voltage and a voltage resulting from rectifying part of an output and controlling the attenuation of a variable attenuator at an input terminal. CONSTITUTION:A voltage detected by a coupler 3 is rectified by a rectifier 4, an error amplifier 5 amplifies a difference between the rectified voltage and a reference input and an output D is obtained via an LPF 6.
