Title: Method for discriminating decay level of photodecayable molding
Inventor: HIROSE KUNIHIRO
IPC: G01N33/44
Filed: 1990-01-22
Abstract: PURPOSE:To discriminate the decay level of a photodecayable molding by providing an index which changes in color by photoirradiation on the molding. CONSTITUTION:The photodecayable molding or photo and microorganism decayable molding is produced by molding a copolymer (ECO) consisting of, for example, ethylene and carbon monoxide and a blend of the ECO and other olefin and is embrittled by photoirradiation. The elongation retention of this time is below 5% and the molding is subjected to color control in such a manner that the color of the index attached to the molding of this time changes. For example, a color-controlled pigment is kneaded into the resin and the resin is molded or the color-controlled pigment is printed on the molding surface or a color-controlled tape is stuck to the molding. The pigment includes, for example, Lake Red C, Lake Red D of an azo system. The photodecay level of the molding formed of the photodecayable resin is known and the adequate execution of land filling and waste treatment is possible.

Title: Two-dimensional/three dimensional image display screen
Inventor: UOMORI KENYA
IPC: G03B21/62
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a two-dimensional/three-dimensional display screen which is provided with and not provided with optical directivity by changing the electric field to be impressed on a refractive index change layer by transparent electrodes, thereby changing the refractive index of this refractive index change layer to the value nearly same as the value of a lens layer or a value different therefrom. SOLUTION: A lenticular lens plate 1 for changing the progressing direction of light and a refractive index variable material 2 variable in the refractive index are superposed on each other. Whether the refractive index of this refractive index variable material 2 is made the same as the refractive index of the lenticular lens plate 1 or the value different therefrom is embodied by switching the magnitude of the electric field to be impressed on the refractive index variable material 2, i.e., the magnitude of the voltage to be impressed on the transparent electrodes 3. As a result, a lens effect is developed by the voltage impression when the refractive indices of both are varied and a transparent plate, such as mere glass plate, is obtd. if the refractive indices are the same.

Title: Electrode take-out structure of ultrasonic vibrator and manufacture of ultrasonic vibrator having the same electrode take-out structure
Inventor: TESHIGAHARA MASAKI
IPC: H04R17/00
Filed: 1989-01-20
Abstract: PURPOSE:To improve operability and a mass-producing property by a method wherein a part of a divided electrode on the rear side of an ultrasonic vibrator is made to be a pad for a turned-round electrode and this pad is connected with an electrode on the front side by a conductive pattern on the lateral side of the vibrator. CONSTITUTION:Five divided electrodes are formed by slits 32 to 35 on the rear side of an ultrasonic vibrator 31, while a pad 37 for a turned-round electrode is formed by a groove 36 intersecting the slits 32 to 35 perpendicularly. Subsequently, a conductive coating is applied on the lateral side of the vibrator 31 and thereby the pad 37 and an electrode 38 on the front side of the vibrator 31 are connected in conductivity.

Patent JP-H03219134-A (JP)
Title: Hydraulic buffer
Inventor: KAGAWA SHINICHI
IPC: F16F9/40
Filed: 1990-01-20
Abstract: PURPOSE:To prevent the generation of noise and obtain a stable damping force characteristic by providing a seal ring with throttle passages communicating with an inner cylinder side gap between a piston rod and a rod guide, and a gas return passage. CONSTITUTION:In a case when gas in a reservoir chamber 29 enters into an inner cylinder 20 due to vibration or the like, the gas accumulated at the upper part in an upper chamber flows upward together with oil liquid from a gap 49 between a piston rod 31 and a bush 35 and passes upward through the throttle passages 45, 46 of a seal ring 40. Because of the small passage area of the throttle passages 45, 46, oil liquid in this case hardly flows, but only gas flows, and the gas having passed through upward opens a check valve mechanism 47 so as to be returned to the reservoir chamber 29. The seal ring 40 is thus fitted into the recessed groove 39 of a rod guide 33 in such a state as to be substantially restricted in its axial movement, so that the seal ring 40 is prevented from colliding with both side faces 43, 44 of the recessed groove 39, and therefore the generation of noise is prevented.

Moreover, fixing members 110, 120 are fixed to the face to almost seal the space. An initial deformation of the diaphragm is eliminated by reducing a pressure in the space (111) defined by the fixing members 110, 120.
