Title: Synthetic resin laminated sheet and vessel made thereof
Inventor: OKADA OSAMU
IPC: B32B27/30
Filed: 1988-11-15
Abstract: PURPOSE:To improve heat moldability, heat resistance, heat insulation heat retaining property, oil resistance, water resistance and rigidity by laminating a specific polypropylene bridge foamed sheet on a polyvinyl chloride resin layer via an adhesive agent layer, and specifying the thickness rate of the polyvinyl chloride with respect to the sheet. CONSTITUTION:A polypropylene bridge foamed sheet 1 of foaming magnification 4 - 15 times, thickness 4 - 5mm, and gel rate 20 - 80% is laminated to a polyvinyl chloride resin layer 2 via an adhesive agent layer 4, and the rate of thickness of the polyvinyl chloride resin layer 2 with respect to the polypropylene bridge foamed sheet 1 is made 20% or below. Herein, as the foaming magnification exceeds 15 times, the rigidity becomes insufficient, and as it is less than 4 times, the heat insulating property is insufficient. Furthermore, as the thickness exceeds 5mm, the heat moldability becomes poor, and as less than 0.4mm, it is not suitable at the point of the rigidity and heat insulating property. In case where the gel rate is less than 20%, the rigidity decreases extremely, and in case it exceeds 80%, the heat moldability becomes inferior. When the thickness rate of the polyvinyl chloride rises above 20%, there occurs rolling nonuniformity in the laminated sheet, and thus, the barrier property cannot be maintained due to rupture or the like.

Title: Optical transmission system
Inventor: MOHAMETSUDO HAJIYU
IPC: H04B10/58
Filed: 1993-11-16
Abstract: PURPOSE: To avoid the deterioration phenomenon of transmission quality connected with a Brillouin effect by providing a means for increasing the modulating speed of an optical carrier wave from a zero value as necessary when modulation is the one other than the intensity modulation. CONSTITUTION: In an optical transmission system including a transmission terminal equipment 1, optical link 2, and receiving terminal equipment 3 a comparator 10 compares the number of the valid carrier waves of an incident multiplex counted by a scanner 9 with a prescribed limit value. Then, when the number of the valid carrier waves of the incident multiplex is detected as less than the prescribed limit value, a control instruction is made active, and the gain of an adjustable gain amplifier 11 is increased and/or an auxiliary carrier wave is added through an auxiliary carrier wave generator 12 and a multiplexer 13.  Thus, when a strong transmission light power is connected, reflection is generated inside the fiber of an optical link 2, and as a result, a phenomenon in which additional attenuation, deformation, and disturbance is introduced to a transmitted signal can be avoided or limited.

Title: Protection device of secondary battery
Inventor: OKUTO TADASHI
IPC: H02J7/00
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To disable the use of a battery when it is excessively charged repeatedly and to prevent the safety of the battery from being lost, by stopping charging using a charge stop signal when a detection voltage is higher than a set value, and breaking the conduction of the battery when the counted value of the output count of the charge stop signal reaches the set value. SOLUTION: When a battery voltage obtained by a voltage-monitoring circuit 2 reaches a set voltage, the output of an overcharge detection means 3 is inverted, thus turning off a charge switch 8 through a switch driver circuit 5 for constituting a charge stop means and hence stopping charging. A counting means 6 measures the output inversion count of the overcharge detection means 3, turns off the switch driver circuit 5, the charge switch 8, and a discharge switch 7 for constituting a breaking means when the count value reaches a set value, thus prohibiting the use of the battery. The counting means 6 is reset by connecting a group of batteries 1 again and can be used again, thus using the battery safely.

Title: Method of forming plate of lead storage battery
Inventor: ASAI KENJI
IPC: H01M4/22
Filed: 1986-12-02
Abstract: PURPOSE:To solve a problem of plates that the formation at the central plate is more difficult than the other plates, by making the formation current flow in the all plates evenly by utilizing a voltage drop owing to the current flowing in the all plates. CONSTITUTION:At first the plate lug 2 of the central plate is connected to a formation power source S, then the plate lugs 2 of the central plate and the plate next from the end plate are connected at the opposite side to the plate 1, and finally the plate lugs 2 of the plate next from the end plate and the end plate are connected at the opposite side to the plate 1 again. By connecting in such a way, the current to be used for the formation of the plates 1 is fed through the plate at the center. Therefore, the voltage goes down by the resistance of the plates 1, and the value of the voltage drop is larger as the voltage goes to the end. The amount of the voltage drop can be controlled in some level by changing the form of the plate lugs 2 or the like. By producing the voltage drop in such a way, the formation reaction can be made easier from the center, the next from the end, to the end plate 1 in this order.
