Title: Leaf spring for car
Inventor: HORI JIYUNICHI
IPC: B60G17/02
Filed: 1982-12-30
Abstract: PURPOSE:To prevent inclination of a car body and variation in a head lamp light axis due to loaded cargoes and to enhance car traveling safety by providing both a leaf spring made of shape memorizing alloy and a heating device that is used to heat the leaf spring to adjust the leaf spring camber. CONSTITUTION:Usually, a leaf spring 1 made of shape memorizing alloy takes the form of a straight line. When the leaf spring 1 deforms and the head lamp light axis varies due to loaded cargoes, a car operator electrifies a nichrome wire in the leaf spring 1 from a heating device 7 by operating a controller 11 in order to heat the leaf spring 1. Thus, the shape of the leaf spring 1 returns to the one memorized before deformation. As a result, the amount of deflection and consequently the inclination of the chassis frame is lessened, putting the light axis back to a normal state. With this constitution, the inclination of the car body and variation in the light axis can be corrected enhancing the car traveling safety.

Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To realize each service of 2-way communication and multiple address communication by one system, to allow the user to receive each service by one radio terminal equipment and to select multiple address communication automatically attended with movement. SOLUTION: A master set 11 sends a multiple address communication message to each of radio base stations 12-1, 12-2. Each radio base station sends the multiple address communication message received through a speech channel and uses a control channel to inform a speech channel through which the multiple address communication message is sent. In the case of a request for 2-way communication during transmission of the multiple address communication message, the 2-way communication is switched. Each of radio terminal equipments 14-1-14-5 receives the multiple address communication message through a speech channel informed by the control channel. Furthermore, when the mobile set is moved, the mobile set receives information of the control channel of the radio base station and selects the reception of a message through the informed speech channel.  When a request of the 2-way communication is received during reception of the multiple address communication message, the reception of the multiple address communication message is interrupted and the 2way communication is selected.
