Title: Mirror, mirror unit, and optical switch
Inventor: AOTA HIROSHI
IPC: G02B26/08
Filed: 2004-10-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a mirror and a mirror unit capable of coping with diffraction of light irradiated to the end part, and to provide an optical switch capable of suppressing the deterioration of an attenuation property by disposing the mirror.  <P>SOLUTION: An MEMS mirror 4 is provided with a part having a lower reflectance as compared to the center part 4a, and the part is disposed on at least a part of the prescribed side end part 4b, with respect to the MEMS mirror 4 having a variable angle of a reflection surface. Because the reflectance of the MEMS mirror 4 on the end part 4b is lower than that on the center part 4a, the influence of the end surface upon the change of angle of the MEMS mirror 4 on light diffraction can be reduced.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Automatic and accurate non-contact type open loop fluid preparation
Inventor: DITROLIO NICHOLAS M
IPC: G01F15/00
Filed: 2004-11-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a pipet for automatically preparing a fluid only by an accurate quantity.  <P>SOLUTION: The flow of the fluid is measured indirectly using a non-linear system model correlated with the vacuum present in the upper part of the interrupted liquid column in the pipet. The sensing of the flow of the fluid required in the case of a contact type closed loop is eliminated by non-contact type operation and a risk of mutual contamination accompanying it is also eliminated. In one embodiment, the open time of a valve is calculated dynamically on the basis of a non-linear system by the electronic controller in a pistol-shaped wireless self-completion type pipetter case. Calibration is used in order to draw out a constant of a formula and, in order to accurately prepare a programmed desired amount of the fluid, the pressure of the vacuum of the liquid column before the valve is opened is used as an independent variable for drawing out the open time of the valve. By a relatively inexpensive portable pipet or device, repeated preparation can be automatically performed in an accuracy of 1% or above without requiring a mechanistically complicated volume type one.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Lure and method for producing the same

Filed: 2004-11-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lure capable of expressing a rainbow color pattern in a wide angle range on the surface of a substrate and being produceable at a low cost and to provide a method for producing the lure.  <P>SOLUTION: The lure 10 is equipped with a substrate 11 in which the surface layer is a reflective layer and a transparent coated layer 12 formed in uneven film thickness on the surface of the substrate 11. When white light (solar light) is incident on the lure 10 constituted as described above, interference occurs between light reflecting on the surface of the transparent coated film layer 12 and light permeating the transparent coated film layer 12 and reflecting on the surface of the substrate 11. Since the film thickness of the transparent coated film layer 12 is formed in uneven state, position at which interference (reinforcement) of light occurs differs by wavelength component of incident light and as a result, interference pattern of rainbow color containing red, green, blue, etc., appears on the surface of lure. Since the transparent coated layer 12 can readily be formed into a film by a vacuum thin film-forming method such as a deposition polymerization method or a physical deposition method and is suitable for mass production of the lure, cost reduction of the lure production can be performed.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide techniques with which reliability of a field effect transistor electrically isolated by a device isolation region having width of <0.3 μm can be improved.  <P>SOLUTION: A device isolation region for electrically isolating a field effect transistor adjacent in a gate lengthwise direction of a mask ROM region is constituted by isolating a field plate that is formed simultaneously with the gate electrode of the field effect transistor. Thus, even if the isolation width of the device isolation region is made relatively narrow to be <0.3 μm, stress generated in an active region ACT held between device isolation regions can be relatively reduced. Thus, the occurrence of a crystal defect caused by the stress can be relaxed or suppressed, and a degree of an unwanted leakage current can be reduced between a source and a drain of the field effect transistor.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
