Title: Optical fiber strand coated with resin curable by uv rays
Inventor: SUETSUGU YOSHIYUKI
IPC: G02B6/44
Filed: 1985-09-27
Abstract: PURPOSE:To prevent the generation of an increase in transmission loss by microbends by providing an intermediate buffer layer consisting of a release agent between an inside coating which consists of a resin curable by UV rays having a low Young's modulus and is formed on the outside peripheral surface of a bare optical fiber and outside coating consisting of a resin curable by UV rays having a high Young's modulus. CONSTITUTION:Powder of a fluoroplastic in addition to silicone resin contg. an Si oil are applicable as the release agent for the intermediate buffer layer. The inside UV resin coating layer consisting of the UV resin having the low Young's modulus is coated by a device 23 for coating the UV resin of the inside layer on an optical fiber base material 21 right after said base material is drawn in a spinning furnace 22. The intermediate buffer layer consisting of a silicone oil is thereafter formed on said layer by using a dipping die 24, then the outside coating layer of the UV resin consisting of the UV resin having the high Young's modulus is coated by a device 26 for coating the UV resin of the outside layer onto the buffer layer and finally the fiber is taken up by a coiler 27. The deterioration in the low temp. characteristic is thus obviated even if the Young's modulus of the UV resin used for the outside layer coating of the UV resin is selected at a substantially high modulus in such a manner that the optical fiber strand coated with the UV resin satisfies the side pressure characteristic satisfactorily.

Title: Sealed lead-acid battery
Inventor: ASAI KENJI
IPC: H01M2/38
Filed: 1986-09-10
Abstract: PURPOSE:To eliminate the concentration difference of an electrolyte by circulating the electrolyte between the upper part of a battery and the lower part with the equipment which transfers the electrolyte accumulated in an electrolyte reservoir to the outside by the variation of the internal pressure of the battery or the outside force. CONSTITUTION:At first, an electrolyte is filled in the bottom of a battery and almost no electrolyte exists in an electrolyte reservoir 5. In this state, by the difference of the liquid level between the bottom and the electrolyte reservoir 5, or the potential energy, the electrolyte rises through a porous separator 4 and is transferred to the electrolyte reservoir 5 through a thin tube 7 until the liquid level becomes equal. When the liquid level became equal, liquid exhausting equipment 8 is operated by sending the air from the outside to transfer the electrolyte from the reservoir 5 to the bottom, and the difference of the liquid level is produced again. By repeating this siphonage, the electrolyte is circulated and the concentration of the electrolyte is made uniform.

Filed: 1983-11-15
Abstract: PURPOSE:To eliminate the variance of write and erasure time due to the variance of threshold value or the like of components by setting a timing applying a saturated boosting potential based on a point of time when the boosting potential of a boosting circuit is saturated. CONSTITUTION:The output terminal of a unit block IN is divided into two paths to constitute the boosting circuit having two output terminals OUT1 and OUT2 and limiters 21, 22 are provided via MOSFET-Q1, Q2. Then a capacitor C is provided to the output terminal OUT1. Thus, a boosting potential different from the boosting speed and equal to the saturation potential is obtained at two output terminals. That is, the boosting characteristic at the output terminals OUT1, OUT2 is as shown in Fig. In this case, the potential difference is small even at the boosting start point. Then a level detection circuit (shown in Fig.) detects for example that a boosted potential of the output terminal OUT2 is a set value VR or over and a saturation detection circuit (not shown) detects that the difference between the two output terminal potentials reaches a prescribed value or below to detect the saturation of the boosted potential. The time when the write/erasure boosting potential is applied is set based on the point of time the detection.

Title: Plate for lead-acid battery
Inventor: FUKUDA SADAO
IPC: H01M4/14
Filed: 1982-12-07
Abstract: PURPOSE:To prevent coming off of active material and increase life by forming a porous rigid layer comprising electrochemically inactive, and acid resistant inorganic powder and an acid resistant inorganic binder on the surface of a plate. CONSTITUTION:SiO2, water, and monobasic aluminum phosphate which is an acid resistance inorganic binder are mixed to form slurry. A positive plate is made by filling an active material in a lead alloy grid by conventional procedure and drying it. The slurry is spreaded on the whole surfaces of the positive plate and dried to form a rigid layer on the surface of the plate for a lead-acid battery. Since slurry is formed by dispersing SiO2 powder in water, the rigid layer is made in porous structure. Thereby, dilute sulfuric acid is easy to diffuse, and coming off of the active material caused by forming fine particles is suppressed, and charge-discharge cycle life is remarkably increased.

Title: Signal processing circuit
Inventor: OKUDA AKIHIDE
IPC: H04N9/78
Filed: 1985-09-30
Abstract: PURPOSE:To decrease apparently a cross color by reducing a gain for a chrominance signal after separation only when a complete YC separation cannot be executed. CONSTITUTION:The circuit constitution of a vertical correlation detecting circuit 4 is a circuit to obtain a vertical correlation quantity (h) from the low area component of an inter-single line difference and an inter-double line difference, and is 0<=h<=1. At the time of the vertical correlation, h=0 is obtained, both the vertical correlation of a luminance signal Y and the vertical correlation of a color difference signal C can be detected by the inter-double line difference and the further, by the low area component of the inter-single line difference, the fine vertical correlation of the Y low area can be detected, and therefore, the highly accurate vertical correlation can be detected. A vertical shaft filter separates a luminance signal Yv and a color difference signal Cv from scanning lines S-1-S1, and the gain of a color difference signal CHV is reduced by an attenuator 8. Y is obtained by subtracting C from S0, when the moving picture vertical correlation generated by the crosstalk are not found, and then, the gain is reduced by the attenuator 8. Thus, apparently, the cross color can be decreased.
