Title: Lens barrier opening/closing mechanism
Inventor: IWAIDA KENICHI
IPC: G03B11/04
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To protect a photographing lens without making a camera larger by rotating a turning ring which opens/closes a barrier by means of a cam provided on two straight advance guides for guiding the straight advance movement of a lens barrel in an optical axis direction. SOLUTION: The straight advance guide 40 is constituted of an upper side straight advance guide 41 and a lower side straight advance guide 42. Therefore, the cam is separated to an upper side cam 411 and a lower side cam 421, and the rotation of the turning ring 3 is performed by rotating upper and lower turning pins 31 by the cams 411 and 421. Namely, the ring 3 is rotated by the cams 411 and 421 provided on two straight advance guides(guides 41 and 42) guiding the lens barrel 6 and installed at nearly symmetric positions. The number of the straight advance guides need not be always limited to two, and two or more guides can be used, but it is desirable that the number of straight advance guides where the cam is provided is two.

Abstract: PROBLEM TO BE SOLVED: To lower a parts count, to simplify structure, to reduce cost, and to obtain stable measurement potential even with the occurrence of changes in pressure, by adhering a single band-shaped body provided with an inner liquid replenishment opening plug and a packing part for compensating for pressure each at different locations to a reference electrode tubular body. SOLUTION: A band-shaped body 2 is formed of a silicon rubber formed body with elasticity, and an inner liquid replenishment opening plug 21 tightly fitted in an inner liquid replenishment opening 11 of a reference electrode tubular body 1 and a packing part 22 for compensating for pressure fitted in a pressure compensation hole 12 are integrally formed each at different locations. An adhesive is applied to the inner surface of the band-shaped body 2, and the band-shaped body 2 is adhered and fixed to the groove part of the reference electrode tubular body 1. As the band-shaped body 2 is provided with a function of replenishing a reference electrode inner liquid 7 and a function of compensating for its pressure, a parts count is low, and constitution is simplified to reduce cost.  In addition, as the packing part 22 is elastically deformed inward according to changes in hydraulic pressure, a state of equilibrium in pressure is achieved between the reference electrode inner liquid 7 and an ambient sample liquid to obtain stable measurement potential even with the occurrence of changes in pressure.

Title: Motion detecting system
Inventor: TANAKA YUTAKA
IPC: H04N17/02
Filed: 1988-12-21
Abstract: PURPOSE:To prevent the degradation of a received picture due to the mismatching of transmission and reception for motion detection even when the band of the motion detection in a reception side is narrow by executing motion decision separately to the several bands. CONSTITUTION:The frequency band of an input video signal is divided into the plural bands by a filter 11, 12 and to the respective divided bands, the motion detection of a picture is executed by motion detection circuits 1, 13, 2 and 14. Then, an obtained result is decided by a logical deciding circuit 15 singly or with coupling plural results. Based on the decision, the band of a transmitting signal is limited. Thus, when the frequency band of the video signal as the object of the motion detection is different in the transmission side and reception side, the generation of the degradation in the received picture can be eliminated.

Filed: 1990-11-27
Abstract: PURPOSE:To suppress a deterioration due to the moisture in a phosphor and to extend the service life by mixing a specific amount of inorganic moisture absorbent to one side or both of a phosphor layer and an insulator layer. CONSTITUTION:As an inorganic moisture absorbent, a white or transparent substance with the particle diameter 5 to 10mum is used, and it is selected from zeolite, a silica gel, an active alumina, a calcium oxide, a barium oxide, and a silicon oxide.

Inventor: ARAHA SATOSHI
IPC: F23G7/12
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To prevent extraordinary temperature-rise within an incineration furnace, and also prevent dispersion of noxious gas and leakage of a toxic substance in incineration residual ashes by incorporating an inorganic compound having a BET specific surface area of a specific value or more after incineration in thermoplastic resin at a specific ratio relative to bag total weight. SOLUTION: As a material of a bag, thermoplastic resin is filled with an inorganic compound having a BET specific surface area of 30 m<2> /g or more after incineration at 10-50 wt.% relative to the bag total weight. Aluminum hydroxide (zeolite, clay, silicate or the like) is appropriate as an inorganic compound. Aluminum hydroxide releases crystal water in a high temperature condition in an incineration furnace, and is transited to an active alumina (transition alumina) having a high specific surface area. The reaction has an effect to reduce a combustion temperature in a furnace. An inorganic compound having a BET specific surface area of 30 m<2> /g or more after incineration absorbs harmful components such as HCl, dioxin, etc. In addition, the compound absorbs heavy metal ions in incineration residual ashes, and prevent them from being dissolved in reclaimed land.

Title: Rectangular at vibrator
Inventor: ENDO HIDEO
IPC: H03H9/19
Filed: 1990-11-26
Abstract: PURPOSE:To avoid increase in a series equivalent resistance (CI value) of a crystal resonator when the size of the rectangular AT vibrator in the X direction is limited small by reducing the thickness of the rectangular AT vibrator in the direction X from its center in a reciprocal of an exponential function. CONSTITUTION:Convex processing is applied to the rectangular AT vibrator in the direction X to reduce the thickness of the rectangular AT vibrator in the X direction from the middle of the rectangular AT vibrator in reciprocal of an exponential function. Thus, while the displacement of vibration in the middle of the rectangular AT vibrator is increased, the displacement of vibration is ideally reduced toward the end of the rectangular AT vibrator in the X direction, thereby realizing the energy confinement in the direction X strongly. Thus, the size of the rectangular AT vibrator is limited to be small, the increase in the CI is suppressed.

Abstract: PURPOSE: To stably and accurately detect a servo data area. CONSTITUTION: A regenerative signal from a magnetic head 7 is amplified by an amplifier 9, and is then inputted to a data recording and reproducing circuit 11 and a servo data reproducing circuit 14. A data is extracted from the regenerative signal by the data recording and reproducing circuit 11 using a slice level voltage for detecting a peak of the data.
