Abstract:
A crimping terminal joined with an aluminum electric wire, in which when the crimping terminal is crimped to the wire, a conduct-purpose crimping portion and a wire-hold crimping portion are formed at a crimping portion of a wire barrel of the crimping terminal. The crimping portion of the wire barrel is formed so as a curvature thereof is projected upwardly in a direction of moving a crimping die and so as a crimp height increases and a compression ratio decreases towards an insulation barrel of the crimping terminal. The curvature is shaped to have a constant degree of curvature, and is shaped to form a quadratic curve as a result of strictly adjusting a crimping force.
Abstract:
A mounting structure for installing an electrical appliance module for mounting on the vehicle on board equipment of the instrument panelboard of the automobile wherein the connection of the connector of the wire harness of the body side is performed reliably and smoothly. There are provided a connector accommodating section B for the instrument panel P as the vehicle on board equipment, and a module mounting section 13 for the receptive connector C. The module mounting section 13 allows the receptive connector C to mount on the connector accommodating section B, and it allows the introducing projection 14 of the receptive connector C to insert into the fitting groove 3 provided at the electrical appliance module A. The electrical appliance module A can thus be assembled to the instrument panel, and the terminal of the electrical terminal receptive connector C of the electrical appliance module A is connected to the instrument panel.
Abstract:
To eliminate an ambient temperature correcting sensor and further to improve the sensor response speed in a heat radiating type liquid level sensing system, a constant current pulse is periodically passed through a level sensor to heat it; level sensor voltages sampled at predetermined time intervals when the level sensor is being heated are divided by each initial sensor voltage to obtain sensor voltage ratios with respect to time; an approximate voltage is calculated on the basis of the the obtained ratios in accordance with an approximation equation; a liquid level is calculated and displayed on the basis of the calculated approximate sensor voltage. Further, it is preferable that the system is provided with an additional inclination correcting sensor or an acceleration sensor, in order to correct the inclined liquid level.

Abstract:
A wire harness includes a standard connection circuit part which connects a standard electronic device and an ECU, and an optional connection circuit part which connects optional electronic devices and the ECU. The optional connection circuit part includes a communication connector which is provided to be connectable to the optional electronic devices, and an optional circuit which connects the ECU to the communication connector. The communication connector performs multiplex communication which multiplexes communication of the optional electronic devices and the ECU.
Abstract:
The first connector includes a first connector housing and a second connector housing movable to and from said first connector housing, and the second connector includes a third connector housing to be coupled with the second housing. The first connector housing incorporates a connection terminal, said second connector housing incorporates a movable contact piece arranged within a terminal chamber and slidably coupled with said connection terminal, and the third terminal incorporates an electrical contact piece to be electrically connected to said movable contact piece. The first connector is mounted on a first mounting module, and the second connector is mounted on the second mounting module. The first mounting module and the second mounting module are coupled with each other. When the second connector housing is moved toward the third connector housing of the second connector, electrical connection between both connectors and fixing of the coupled mounting modules can be simultaneously carried out.
Abstract:
An image forming apparatus having a developing device which accommodates a developer for developing an electrostatic latent image formed on the surface of a latent image carrier, a developing member provided in said developing device for supplying the developer to the electrostatic latent image formed on the surface of the latent image carrier and a mixing member provided in the developing device for mixing the developer accommodated within the developing device. In the above image forming apparatus, the operating time of the mixing member is determined prior to the start of operation of the developing member based on at least one value of a toner density at the end of developing, the developer standing idle time, and the total number of developing cycles with the same developer.
Abstract:
An angular velocity sensor for detecting angular velocity by converting deflection caused by the coriolis force into an electrical signal. The sensor includes a vibratory member having at least three main surfaces including a first main surface having a driving transducer provided thereon, and second and third surfaces substantially perpendicular to the first main surface respectively, and being parallel to each other, the second and third main surfaces having detecting piezoelectric transducers, respectively. Additionally, support members are connected to the second and third main surfaces to respectively support vibration-steady points of the vibratory member. At least one longitudinal end portion of the vibratory member has a cross-section in such a manner that a length between the second and third main surfaces is shorter than a length of the first main surface. In this manner, the sensitivity of the angular velocity sensor is improved.
