Title: Charge control circuit
Inventor: IKEDA MASAKI
IPC: H02J7/10
Filed: 1992-10-27
Abstract: PURPOSE:To prevent the restriction on a charge current from occurring before it reaches full charge and besides, prevent the waiting time to the start of detection of temperature rise from becoming unreasonably long by stopping the detection of temperature rise while a timer continues its time-limited operation since the start of charge. CONSTITUTION:This circuit is equipped with a charge control circuit 5 which limits the charge current by detecting the temperature rise of a battery 1 for charge per unit time, based on the temperature detection signal from the temperature sensor 2 for detecting the temperature of the battery 1 for charge. Moreover, this charge control circuit 5 stops the detection of the temperature rise during the time-limited operation by operating a built-in timer only within a limited time at the start of charge. The time of the time-limited operation of this timer is set, corresponding to the battery temperature at the start of charge. What is more, even if the timer is in the time-limited operation, if the battery temperature goes up to the charge ambient temperature, it starts the detection of the temperature rise so as to prevent the period of its stopping the detection of the temperature rise from becoming unreasonably long.

Title: Manufacture of insulated wire
Inventor: SANO BUNICHI
IPC: H01B13/16
Filed: 1989-11-09
Abstract: PURPOSE:To sharply reduce residual solvent quantity and also reduce the oxidation deterioration of an insulating layer by repeating coating and baking step of an insulating varnish several times to form a desired insulating layer, and then heating it under an inert gas stream, when the insulating varnish is applied onto a conductor followed by baking to form an insulated wire. CONSTITUTION:A polyurethane insulating varnish, for example, is applied onto a conductor formed of a copper wire at a speed of 200m/min by use of a squeezing tool of felt, and baked at 350 deg.C. This process is repeated about five times. The insulating varnish is not particularly limited, but the effect is increased against varnishes such as polyurethane, polyamide, and polyimide having large residual solvent quantities. Thereafter, thermal treatment is conducted at about 300 deg.C while sending an inert gas such as nitrogen, helium, argon and carbon dioxide in opposition to the forward direction of the wire at a rate of 1m/sec. When nitrogen and carbon dioxide are used as the gas, the cost is reduced.
