Title: Manufacture of hybrid bipolar electrode plate
Inventor: OKADA YUICHI
IPC: H01M10/18
Filed: 1991-07-15
Abstract: PURPOSE:To improve the life performance by applying lead plating to a lead- antimony alloy plate, then peeling off a plated layer from only one face. CONSTITUTION:When a plated layer is peeled off from only one face after lead plating is applied to a lead-antimony alloy plate, a lead-antimony alloy is exposed on one face, and a lead alloy containing no antimony is exposed on the other face. Spongelike lead serving as a negative electrode active material is held on one plated face. Lead dioxide serving as a positive electrode active material is held on the other face of the exposed lead alloy plate containing antimony to manufacture a bipolar electrode plate. The bipolar electrode plates are laminated while separators made of fine glass fibers and having a liquid retaining property are arranged between the bipolar electrode plates to manufacture a battery. A self-discharge and the generation of nonconducting corrosion layers are prevented, the alloy composition of a current collector can be used for a positive electrode and a negative electrode, and the life characteristic can be improved.

Title: Knocking controller of internal-combustion engine
Inventor: NAKAMURA NORIHIKO
IPC: F02D15/04
Filed: 1982-11-19
Abstract: PURPOSE:To suppress generation of a knock without causing the worsening of fuel consumption of an engine, by mounting a knock sensor to the engine so as to delay the closing timing of an intake valve when the knock is generated while to advance the closing timing when the knock is not generated. CONSTITUTION:A knock sensor 80 being the detecting element of mechanical vibration is mounted to the main unit of an engine 10, and its output signal is input to a controller 81. The controller 81, if it recognizes generation of a knock, drives a motor controlling a variable valve timing mechanism 41 provided in a cylinder head 14, so that the closing timing of an intake valve is delayed to decrease the effective compression ratio and to suppress the generation of the knock. While, if no generation of knock is recognized, the closing timing of the intake valve is advanced to increase the effective compression ratio. By this method, fuel consumption of the engine can be improved as compared with that by the method of delaying the ignition timing at the generation of the knock.

Title: Solenoid valve drive device
Inventor: ARIKAWA FUMIAKI
IPC: F16K31/06
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a vibration and a noise at the time of landing and improve durability of a valve by decreasing a landing speed. SOLUTION: The subject unit is so composed that a lower spring 21, energizing a valve 1 in the closing direction, and an upper spring 22, energizing the valve in the opening direction, are composed by combining two kinds of coil springs having different free length, 21a and 21b, and coil springs, 22a and 22b, respectively, so that a composite spring constant may become high just before closing or opening the valve. At the time of closing the valve, an armature 6, moving integratedly with the valve 1, moves upward resisting a spring force of the upper spring 22 and is attracted by an upper solenoid 52, but at that time, the speed of the armature 6 is rapidly decreased because a spring constant becomes high just before closing the valve. Therefore, a landing speed of the valve 1 becomes very low, so a vibration or a noise can be prevented.

Abstract: PURPOSE:To ensure stable transfer of signal with a magnetic recording/ reproducing device by providing a tension head to give a prescribed tension to a magnetic tape and contacting slidingly the tape to a magnetic head with fixed contact pressure. CONSTITUTION:A tension head 14 is provided at the upstream side of a magnetic head 11 set on a head mount 9 when viewed from the driving direction 7 of a magnetic tape 6. Thus the tape 6 is held between the head 14 and a pressure pad 13. The magnetic tape 6 is held between the entire surface of the pad 13 and the entire part of a tip part 14' of the head 14.
