Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To improve an appearance. SOLUTION: A green colored film 112 capable of obtaining the light of an umber color when passing through a colored lens is applied to an inside surface 11 of a lamp housing 1, so that when lighting a light source bulb, the light of an umber color is irradiated outside in a prescribed light distribution pattern. Thus, a colored cap is obviated, so that the number of part items and a cost can be reduced by that extent. Since the colored cap is not used, among the colored cap, a part close to the colored lens is not seen as a functional color via the colored lens.

Title: Injection molding machine and its injection molding method
Inventor: TANIGUCHI YOSHIYA
IPC: B29C45/80
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To suitably and rapidly control compression velocity and pressure of a mold having a servo motor for controlling, a position of the mold, and injection velocity of metered resin by providing an injection mechanism for injecting resin to the mold. SOLUTION: An injection servo motor 11 is operated at the time point of completing resin metering, and metered melted kneaded resin 3a stored at an end part of an injection cylinder 13 is injected in a mold cavity 2. An injection velocity of a screw 4 is controlled by comparing an output signal of an injection load cell with a set value by a controller 8, and an injection servo motor 12 is controlled to trace the set value. In a pressure control range at a front stage of a dwelling step, resin pressure in the cavity 2 is directly detected and controlled by a pressure sensor 54, and compression pressure substantially near the set value is given to the charged resin 3. Under the control of a position of a rear stage, the resin 3 of a predetermined amount is charged in the cavity 2 at each time, and hence when a detected value of the sensor 54 is constant, its thickness becomes constant, and hence the mold control is accurate, and mold clamping is executed with strong pressure.

Title: Charging system for sealed lead acid battery
Inventor: JINBO HIROYUKI
IPC: H01M10/44
Filed: 1989-05-12
Abstract: PURPOSE:To enhance the life characteristic for charging/discharging cycles under rapid charging by starting a forced charging timer when the charge current has sunk to a specific sensing current, charging with a constant current below the sensing current, and by finishing the charging when the timer is ended. CONSTITUTION:In constant-voltage, constant-current control with the charge current under 2.0CA, the charge sensing current is set below 0.20CA, and a forced charging timer is started when the charge current has sunk to the sensing current. During the timer in operation the charge shall be made with a constant current below the charge sensing current, and the charging electric amount at this time is within 10% of the battery capacity, and the charging is finished after the time has gone out. Thus a proper balance of the charging electric amount for the discharge electric amount is obtained even in case with a large charging current by setting the charge sensing current and forced charge timing to appropriate values, that should enhance the life characteristic for charging/ discharging cycles of a battery.

IPC: B65H35/06
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of wrinkles in a winding start section by making the cut shapes of a web uniform. SOLUTION: Cutters 51a and 51b are arranged in a stay 50 fixed to a cutter arm 11 symmetrically with respect to the center of a web 3 such that the cutter faces thereof are roughly placed on the same plane. During cutting, the cutters 51a and 51b are moved toward the ends of sides away from positions over the center of the web 3 to cut the same. During the period from the cutting-in of the web 3 by the cutters 51a and 51b to the reaching thereof to the end parts, tension is applied to both sides of the width direction of the web 3, and thus wrinkles in the cut parts are prevented, and undefined tearing is prevented. Also, since the shapes of the cut parts are chevron and a difference between the center and both end parts is small, wound parts become almost flat.
