The electric wire fixture device is provided with a bottom wall on which the electric wire is placed, and a side wall upstanding from the bottom wall. The side wall is provided with an aperture passed through by a fixing member for fixing the electric wire. The fixing member fixes the electric wire so that the fixing member passes through the aperture after being wound around the electric wire and that the electric wire is then brought close to the side wall. The side wall is provided with a pair of ribs projecting toward the electric wire from the side wall. The pair of the ribs is disposed spaced along a longitudinal direction of the electric wire, and the pair of ribs is disposed to position the aperture therebetween.

The present invention provides a waterproof box which can improve water performance and work efficiency, and can reduce space. When washing water hits in the lower surface 33h of first waterproof portion 33 of an upper cover 15, spay is generated. At this time, an outer surface 30b, which is formed in a tapered shape, of first waterproof portion 30 abuts on an inner surface 33g, which is formed in a tapered shape, of the first waterproof portion 33. Further, the outer surface 30b engages with the inner surface 33g. As a result, the inlet of a minute path 27 is closed. Even if water leaks, force of the water is reduced because the water enters in a groove 33b or 35a. The water in which force of the water is reduced falls down.

In one arrangement of press contact terminals, each press contact terminal (1) includes an electric contact part (2), a bent part (4), and a press contact part (3) for being connected with an electric wire. The electric contact parts (2) are arranged in line, the bent parts (4) are bent alternately forward and backward in perpendicular to the line for arranging the press contact parts (1) alternately in different directions. Each press contact terminal (1) has an identical shape. In another arrangement, press contact terminals (17), (18) include shorter bent parts (19) and longer bent parts (18) respectively. The electric contact parts (26) are arranged in line. The bent parts (19), (20) are bent in one direction perpendicular to the line, and alternately arranged. In the other arrangement, neighboring press contact parts (2) of the press contact terminals (1) overlap each other in a direction perpendicular to a line in which the press contact terminals (1) are arranged.

Terminal having an interfering projection 4 for preventing a wrong insertion of a coupling terminal 3 is formed in a terminal accommodating section 2 of an upper casing 1, whereby the terminal 3 is received in a gap 12 between a resilient contacting portion 10 and a peripheral wall 11 of the terminal when the terminal is inserted in a proper orientation, while the terminal abuts against the interfering projection 4 when inserted in a wrong orientation. The resilient contacting portion 10 is further provided with a male tab contacting portion 15 having a slanted piece 13 which is bent near the upper end (namely upper bent end) 10a of the rear wall of the peripheral wall and slanted downward, and a busbar contacting portion 16 which is a continuation from the male tab contacting portion 15 and bent in the lower center portion (namely lower bent end) 10b of the peripheral wall to extend upwards therefrom, wherein the interfering projection 4 enters into a space 12 between the slanted portion and the front wall 11a of the peripheral wall 11 when the terminal 3 is properly inserted, and abuts against the upper or lower bent end of the resilient contacting portion 10 when not inserted properly.
摘要:
Bidirectional transmission of write and read data is effected between a reader/writer unit and a memory module in a contactless manner using electromagnetic induction coupling. A single magnetic induction coupling apparatus is provided for each of the reader/writer unit and the memory module. In the electromagnetic induction coupling apparatus of the reader/writer unit, a transmitting coil and a receiving coil are coaxially wound around a single magnetic core. In the electromagnetic induction coupling apparatus of the memory module, a single coil which is commonly used for transmission and reception is wound around a single magnetic core. A reception signal of the transmitting/receiving coil of the memory module is rectified and smoothed by a power source circuit, thereby forming an operating power source of the memory module. The power source circuit has a backup capacitor. In the transmitting mode in which no power source is externally supplied, the operating power source is supplied from the backup capacitor.

Between two units which are separately arranged, a power source signal is supplied from one of the two units to the other unit via electromagnetic induction coupling by using induction coils, and data signals are mutually transmitted and received between both of the units. A change in coupling distance between the induction coils provided for the two units is detected from a signal level of a reception signal from the unit which receives the power supply. When the reception signal level decreases, the signal level of the power supply signal is increased.

Vehicle information such as vehicle speed, engine rotational speed when a vehicle runs are collected and converted into numerical data every constant period of time and these numerical data are written and recorded into a memory module. The memory module has therein a non-volatile memory and is detachably provided to a write unit attached to the vehicle. The data writing and power supply to the memory module from the write unit are executed by the contactless coupling using induction coils.

An external system for preparing information tables is connected by a connector to a digital valve control system which controls a digital valve by driving a pulse motor according to the information tables. The digital valve control system stores in the memory a first information table for determining the control amount for the digital valve and a second information table for determining the interval between the generation of motor driving pulses. The first information table for determining the control amount is fixedly stored in the memory and the second information table for determining the type of control pattern is stored in the memory which is capable of writing and reading the information which can be freely prepared, corrected and modified by the external system. The second information table is prepared by the keyboard of the external system, transferred to the digital valve control system and written in the memory. The digital valve is actually controlled by using the prepared information table to check the load condition and the correction of the second information table is repeated by the external system until the optimum result is obtained, and the external system is then disconnected when a desired control characteristic is obtained.
摘要:
A memory is built in a tool holder to which a working tool such as drill or the like is attached. Various tool information such as kind of tool, dimensions of tool, tool use time, and the like is written into the memory. The tool holder having the memory therein is coupled with an external unit by contactless coupling means which doesn't need any electrical coupling, thereby allowing the tool information to be written into or read out of the memory. The information is transmitted between the memory in the tool holder and the external unit by way of the optical or magnetical coupling. The memory built in the tool holder consists of a non-volatile memory such that the memory content is not erased even if the power supply is shut off.
