Title: Integrated circuit amplifier for adaptive offset and its method
Inventor: HANNA JOHN E
IPC: H03F1/02
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To provide an integrated circuit amplifier that sets a bias voltage of a converter to minimize a standby current. SOLUTION: A warning amplifier 10 has an operational amplifier 30 that sets a bias of a peak detector 22 and a converter 32 dynamically to minimize a standby current. When no input call signal is received at an input terminal 12, the standby current in the converter 32 is zero. A bias voltage to the converter 32 is adjusted below a reference voltage in response to the input call signal to minimize a voltage in the converter 32 while the warning amplifier 10 is activated.

Filed: 1981-12-11
Abstract: PURPOSE:To provide an electrode plate having a right shape and dimension by punching a reference hole at constant intervals in the center in the width direction of a lead alloy sheet and making expanding, then forming a lug for current collecting by using the reference hole as a reference. CONSTITUTION:A lead alloy sheet 11 is fed to reference hole punching equipment to punch a reference hole 1e at constant intervals in the center in its width direction. A mesh part 1a is formed in the center in the width direction of the sheet 1 except for required width dimension with an expanding machine. The sheet 1 is supplied to a forming machine using the reference hole and a punched portion 1b is formed in the center which is not expanded and the mesh part 1a is reformed with a press. Since the punched portion 1b coincides with the center between mesh portions 1a, width dimension of a lateral bone which supports current collecting lugs 1c is uniform and battery performance is stabilized.

Title: Method of detecting inactivation of oxygen-concentration sensor in air-fuel ratio feedback control system for internal-combustion engine
Inventor: TOMOSAWA KIKUO
IPC: F02D41/14
Filed: 1983-10-25
Abstract: PURPOSE:To enable to judge the inactivated state of an O2-sensor with high accuracy, by increasing or decreasing the count number of a counter representing tha inactivated state of the O2-sensor according to the temperature of exhaust gas, and making judgement that the O2-sensor is in its inactivated state when the count number of the counter has reached a prescribed value. CONSTITUTION:In operation of an engine, the base injection period determined on the basis of the output signals of a crank-angle sensor 13 and a sensor 11 for detecting the absolute intake pressure is corrected by a control circuit 16 according to the output signal of an O2-sensor 14 in its activated state. In judging the activated state of the O2-sensor 14, the count number of a timer counter is decreased at a first prescribed speed V1 at the time of engine operation such as ''fuel cut'' operation and idling operation when the temperature of exhaust gas is lowered. On the other hand, at the time of engine operation other than the above when the temperature of exhaust gas is raised, the count number of the timer counter is increased at a second prescribed speed V2 (V2<V1). When the above count number has reached a predetermined value (=0), judgement is made that the O2-sensor 14 is in its inactivated state.

Title: Brake frictional member
Inventor: TAKEI YOSHIKI
IPC: F16D69/02
Filed: 1990-07-27
Abstract: PURPOSE:To prevent the reduction of frictional coefficient and improve abrasion resistance by using a condensation polycyclic aromatic hydrocarbon resin and compounding copper fibers in 10-50wt.% into a basic material, in a brake frictional member consisting of the basic material compounded with lubricating agent, fillers, bonding agent, etc. CONSTITUTION:A condensation polycyclic aromatic hydrocarbon resin which is used an bonding agent for brake frictional member does not contain the group such as-OH,-CH2,-CH2OH, etc. Since, even if the temperature of a pad rises, gas is not generated from the bonding material, the reduction of the frictional coefficient is prevented. Further since at least one between copper fibers and copper powder is compounded as the basic material in 10-50wt.% for the brake frictional member, the superior abrasion resistance can be obtained. Accordingly, the reduction of the frictional coefficient can be prevented, and at the same time, the abrasion resistance can be improved.
