摘要:
A protection arrangement for a battery charger of the type used to charge battery packs used for electromotive tools. A self-holding protector is arranged in the neighborhood of an inserting hole of the battery charger for receiving a storage battery pack 50 to be charged. This self-holding protector element includes two elements electrically connected in parallel. One of these two elements is a bimetal which opens when it heats or flows too much current. The other of the two elements is a positive characteristic thermistor (PCT) which generates heat when a current flows through it. When a battery pack being charged becomes over-charged and heats, the bimetal element of the protector opens, and charging current stops flowing. When the bimetal element opens, electric current flows through the PCT. This current causes the PCT to heat and maintain the bimetal element in its open condition. When the battery pack being charged short-circuits, and a large current flows through it, the bimetal element opens and charging current is interrupted in the same way.

A method of manufacturing an electronic component which can reduce voids in a solder and can reliably melt the solder is provided. The method of manufacturing an electronic component including a member (substrate 1) having a metal junction (electrode 11) includes: the step of supplying a solder 5 containing a solvent, a resin component, an activator, and a brazing filler metal to the junction (electrode 11); the first heating step in which a first heating process to the solder 5 is performed and the solder 5 is kept at a first heating temperature for a predetermined period of time; the second heating step in which a second heating process to the solder 5 is preformed and the solder 5 is kept at a second heating temperature higher than the first heating temperature for a predetermined period of time to vaporize the solvent and the resin component; and the third heating step in which a third heating process to the solder 5 is performed and the solder 5 is melted.

A charging system includes an electric power tool (2) and a charger (1) having internal rechargeable batteries (6) and a controller (9) for monitoring the charge/discharge level of the batteries (6). The electric power tool (2) additionally includes a pair of charge terminals (13a, 14a) for carrying current to charge the batteries (6), a temperature terminal (15a) for outputting to the charger (1) data on the temperature of the batteries, and a data terminal (16a) for outputting to the charger data on the battery charge/discharge level from the controller (9). The charger (1) includes a pair of charge terminals (13b, 14b), a temperature terminal (15b), and a data terminal (16b) that are electrically connected to the corresponding tool terminals when the tool (2) is set on the charger for a charge. The charging system indicates the remaining charge level on an indicator unit (4) based on the received data on the battery charge/discharge level and changes the amount of the charging current based on the data on the battery charge/discharge level and the battery temperature data received from the tool (2).

摘要:
An apparatus for controlling the amount of secondary air fed into an internal combustion engine which includes means for controlling the response speed of a secondary air flow control means in accordance with an electrical signal. This signal is generated by integrating the value of an intake air amount signal, which is generated by multiplying the rotational speed of the engine and the load of the engine, in an interval direction determined by an equivalent air-fuel ratio condition of the engine. Thus, the equivalent air-fuel ratio can be controlled with a response speed corresponding to the amount of the flow of the exhaust gas. Furthermore, excessive control of the equivalent air-fuel ratio can be prevented.

An apparatus for controlling the amount of secondary air fed into an internal combustion engine includes means for controlling the response speed of a secondary air flow control means in accordance with the amount of exhaust gas emitted from the engine. Thus, the equivalent air-fuel ratio can be correctly controlled, without delay, in response to changes in the operating condition of the engine.
摘要:
A communication device includes a processor and a memory. The memory stores computer-readable instructions therein. The computer-readable instructions instruct the processor to acquire media data comprising one or more of image data and audio data from an acquiring device. The computer-readable instructions instruct the processor to encode the acquired media data to generate particular encoded data. The computer-readable instructions instruct the processor to determine whether a data size of the particular encoded data is equal to or greater than a threshold data size. The computer-readable instructions instruct the processor to encode the particular encoded data using redundancy processing to generate redundantly-encoded data when determining that the data size of the particular encoded data is equal to or greater than the threshold data size. The computer-readable instructions instruct the processor to transmit the redundantly-encoded data as one or more packets to another communication device.
