Abstract: A battery frame is fixed to a chassis and a battery pack is assembled to the battery frame. The battery frame includes a pair of crossbars and a pair of side bars. The crossbars extend in the vehicle width direction while being spaced apart in the vehicle front-rear direction, and have both ends in the vehicle width direction fixed to the side members. The side bars extend in the vehicle front-rear direction while being spaced apart in the vehicle width direction, and have front ends and rear ends detachably fixed to the crossbars.

Abstract: A wireless communication network system including: mobile radios mounted on a moving body moving along a predetermined route; and a plurality of immobile radios arranged along the route, adjacent immobile radios wirelessly communicating with each other, to transmit information from a transmission source to a terminal by relaying the information. The mobile radios and the immobile radios communicate with each other by a time division multiple access method, in which time synchronization is performed to allow each of the mobile radios and the immobile radios to communicate in an allocated time slot. The mobile radios are disposed on front and rear parts of the moving body and are capable of communicating with each other. When the moving body is between the immobile radios arranged to be capable of wirelessly communicating with each other, the two mobile radios is capable of relaying information propagation between the immobile radios.

Abstract: A dial unit is detachably mounted on a public telephone for equal access and includes a keypad section, a registration table section, a determination processing section, and a transmitting section. The keypad section key-inputs a dial signal. In the registration table section, area codes corresponding to specific destinations to be handled as a long-distance call and a carrier code corresponding to a specific carrier line having a right of a carrier to the specific destinations are registered in advance. The determination processing section includes a dial signal determination section for determining whether or not the first digit of a dial signal to be handled for a long-distance call coincides with either a "1" or a "0", a dial signal storage section, an equal access determining section, and a carrier code adding section.

Abstract: A multi-purpose timer comprising a control member, a first and second slide plates which can be operated by the control member, a microswitch which is operated by the first slide plate, a "snooze" actuating member connected to the second slide plate, a "snooze" operating member which is engageable with the second slide plate, a switch operating lever which is engageable with the first and second slide plates, and a timer setting drum, the timer mechanism, "sleep" mechanism and "snooze" mechanism being selectively used by change-over operation of the control member.
