Abstract: To provide an easy-to-use electric chainsaw that uses, in place of a large battery pack with a high voltage rating that would have been used in conventional electric chainsaws, a battery power source composed of a set of small commonly used battery packs of the same rating. An electric chainsaw having a built-in electric motor that is powered by a rechargeable battery, wherein a set of commonly used battery packs of the same rating is used as the rechargeable battery. The set of battery packs is mounted at the back of the main housing so that the center of gravity (G) of the chainsaw is positioned within a range (R) of 1.5 time the width (W) of the grip section of a rear handle between the left and right sides of a center line that is centered in the horizontal direction.

Abstract: A train travel prediction device includes a required time database that records a station-to-station required timetable created in advance between stations and indicating a relation of a time difference between a last station departure time of a target train and a next station departure time of a precedent train with respect to a required time of the target train to a next station by the use of a train simulation on the basis of a train moving condition and an operation prediction unit that creates a prediction schedule on the basis of information of the required time acquired for each target train during a prediction period by referring to the station-to-station required timetable recorded in the required time database on the basis of information of a train schedule and a train arrival-departure time.

Abstract: An electric chainsaw includes a first handle having a grip portion that is provided with a trigger switch for activating an electric motor. The electric chainsaw includes a second handle having a laterally extending grip portion provided forward of the grip portion of the first handle. The electric chainsaw includes an indicator lamp for indicating a remaining charge amount of a battery pack, and a push-button type indicator switch for causing the indicator lamp to indicate the remaining charge amount. The indicator switch is provided at a position where the worker can operate the indicator switch by a finger of the other hand gripping the grip portion of the second handle.

Abstract: A money processing apparatus that performs input/output processing of money in a money unit configured to be pulled out from a casing and opened includes an actuator provided in the money unit; and an engagement portion provided in the actuator, configured to engage with the casing to lock pulling out or opening of the money unit in a stopped state due to power cut.
