Title: Portable unit
Inventor: FUKUMOTO MASAAKI
IPC: H04M1/02
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a portable unit that can stably send/receive voice and can have excellent carrying performance when the mobile unit is not in use although a user can easily grip the portable unit. SOLUTION: This portable phone is provided with an upper unit 23 having a speaker 11 and a display section 12, a lower unit 24 having a keyboard section 13 and a microphone 14, and a slide bar that connects them. Since the slide bar 25 is formed thinner than the upper unit 23 and the lower unit 24, the shape of the portable phone itself is shaped close to a classical 'handset' so as to allow a user to easily grip the mobile phone. Since the speaker 11 and the microphone 14 are largely apart from each other, they are placed in the vicinity of the ear and the mouth of the user in the case of making a speech respectively. When the portable phone is not in use, since the size is made small by containing the slide bar 25 to the inside of the upper unit 23 and the lower unit 24 by means of a slot 31 or the like, the mobile phone exhibits excellent carrying performance.

Abstract: PURPOSE:To prevent fixing fittings for a dump door in a dump car from easy pivoting by permitting auxiliary fittings for an operating rod to engage a knotch in the fixing fittings. CONSTITUTION:When a rear dump door 1 is opened preliminarily, a pin 6 is pressed into fixing fittings 5 by pressure of load to the rear dump door 1. As the pin 6 is pivoted, the fixing fittings 5 is pivoted to tend to enter a cavity 8 in receiving fittings 4. However, the fixing fittings 5 is prevented from pivoting by the engagement of the upper end of an auxiliary fittings 14 fixed to a handle 12 with an end surface of a U-shaped groove 7 in the receiving fittings 4. Next, when the pin 6 is removed from the fixing fittings 5, the operating rod 12 is urged in front of a cargo box against force of a spring to make the auxiliary fittings 14 corresponding to a notch of the fixing fittings 15 and then pivot upward so that the U-shaped grooves 7, 10 of the fixing fittings 5 and receiving fittings 4 coincide with each other. Under such condition is removed the pin 6 from both fittings 4, 5.
