Title: Referecne plate for inspecting optical measuring device
Inventor: NAKADA MASAYUKI
IPC: G01B11/30
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To inspect measurement errors of a moire device with a high precision and to make measurements on a light wave interferometer and the moire device by providing the reference surface on which minute luster surfaces are distributed in an approximately uniform manner within the diffuse reflecting surface. SOLUTION: Many minute flat luster surface parts 2B are formed on a reference surface 2 of an inspection reference plate 1 by flatly grinding the peak parts of large rough surface parts 2A so that the parts 2B are uniformly distributed among the parts 2A. Thus, the light beams made incident on the surface 2 become scattered light beams by the parts 2A and become normal reflection light beams at the parts 2B. Thus, directional characteristics 5 of the scattered light beams (reflection light beams) from the surface 2 become the scattered light beams having a certain instensity by adding both directional characteristics and become normal reflection light beams having a strong intensity.  Therefore, measurements are conducted by either the moire device which requires scattered light beam components from the surface of the object to be inspected and the interferometer which requires normal reflection light beam components with an observation image having a good contrast.

Title: Formation of antireflection film
Inventor: SHIMIZU ETSURO
IPC: H01L27/14
Filed: 1993-04-19
Abstract: PURPOSE:To form an antireflection film whose reflectance factor is lower in a method in which the antireflection film is formed in a region other than a light-receiving region on a photoelectric conversion device. CONSTITUTION:A black pigment-dispersed rein film 14 is patterned and formed on a light-shielding Al film 13 on a wafer 11 which is composed of a light- receiving region 12 and of the light-shielding Al film 13 former in a region other than the light-receiving region. Then, only a surface layer 14a in the black pigment-dispersed resin film 14 is dissolved by an organic solvent, and the surface layer 14a is worked to be a microscopic uneven face. The microscopic uneven face acts to confine incident light and reflected light inside the black pigment-dispersed resin film 14, and it is possible to reduce a reflectance factor.

Title: Exhaust device for marine outboard engine
Inventor: SHIBATA YASUHIKO
IPC: F01P3/20
Filed: 1986-05-19
Abstract: PURPOSE:To absorb thermal expansion of an exhaust pipe in order to aim at sustaining a sealing ability, by coupling the exhaust pipe with the outer wall of an expansion chamber through the intermediary of a member which is resilient in the axial direction of the exhaust pipe, and by disposing a sealing member in the coupled section. CONSTITUTION:An exhaust pipe 3 is coupled at the outer periphery of its substantially center section to an exhaust guide 12 by means of a resiliently deformable plate 54 having a flange section 55. A packing member 62 is disposed in the flange section 55 and the upper surface of the exhaust guide 12 so that the exhaust pipe 34 and an outer pipe 42 are sealed. The temperature of the exhaust pipe 34 is raised by exhaust gas from an exhaust passage 22, but cooling drain water normally flows on the outer periphery of the exhaust pipe 34 from a passage 50 so that the thermal expansion of the exhaust pipe may be prevented. However, when an engine is abruptly accelerated, the inflow of the cooling water is insufficient for the high temperature exhaust gas, and therefore, it is liable to cause thermal expansion of the exhaust pipe. The deformation of the exhaust pipe due to the thermal expansion may be absorbed by resilient deformation of the deformable plate 54. Accordingly, it is possible to prevent the packing member 62 from being subjected to thermal stress, thereby it is possible to sustain a sealing ability.

CONSTITUTION:A wring component 2 which has a blade section is engaged with a hull 1 within a range from 0.2 to 1 of the length thereof and directly fixed to the same with a gap (d) so that flow collected by the wring component 2 expands and reaches the rotary surface of a propeller 4. A slat 3 is provided in connection with the front end of the wring component 2. An angle theta between the external board of the hull 1 and the center line SL thereof and angle gamma between a straight line NL connecting the front extremity of the slat 3 and the rear end of the wring component 2 and the center line of the hull SL should have a relation of theta>gamma. Stream at negative pressure side of the blade section is thereby presented from separation, hence generating an intense thrust.

Title: Semiconductor memory device
Inventor: ITO HIDEKI
IPC: H01L27/108
Filed: 1993-05-17
Abstract: PURPOSE:To make high speed operation possible by inserting a capacitor having opposing electrodes between a power supply and a boost power supply thereby preventing the rising of word line potential from delaying and the noise from being generated. CONSTITUTION:A capacitor Ca is connected between a power supply voltage Vcc and the output side of a boost power supply 1. An inverter INV is provided so that a switching TrC for resetting the word line is driven in reverse phase to a TrA. A potential higher than that required for driving a word line WL is generated from the boost power supply 1 and stored in a capacitor having the capacitance higher than the word line thus preventing the rising of word line potential from delaying. Since the boost power supply 1 charges the capacitor Ca when the word line WL is not driven, high driving capacity is not required and thereby noise is suppressed along with the peak value of power consumption. When the opposing potential of the capacitor Ca is set at the power supply voltage Vcc, the electric field being applied to a dielectric can be lowered and the area occupied by the capacitor Ca can be decreased.

Filed: 1983-06-27
Abstract: PURPOSE:To reduce the staining of the ground part of a recorded image without deteriorating its quality by discriminating between the sensitivity decrease of a photosensitive body and a cleaning defect, and removing the cause of the staining of the ground part directly. CONSTITUTION:When the staining of the ground part is caused by the cleaning defect, the photosensitive body 10 is at relatively high temperature, so a temperature sensor 44 decreases in resistance value and a signal for driving a cleaning blade 34 is outputted to increase the abutting pressure of the blade 34 to the photosensitive body 10, reducing the staining of the ground part. When the staining is caused by the sensitivity decrease of the photosensitive body 10, the temperature of the photosensitive body 10 is relatively low and the resistance of the temperatue sensor 44 becomes high to output a signal; and a heat insulating heater 42 is powered on to raise the temperature of the photosensitive body 10, and the sensitivity increases to reduce the staining of the ground part.
