摘要:
A theft preventive apparatus is attached to a commodity or the like exhibited in a shop, for outputting an alarm when detached therefrom.Conventionally, a battery is used as a power source for driving an alarm output device, and power supply is turned on and off by moving the battery. Even in a non-use state, an operation could be started inadvertently by vibration or the like.The theft preventive apparatus of this invention includes an attached state detecting device (3, 103) exposed outside a box (2) for detecting a state of attachment to an object of theft prevention, alarm output means (G) mounted in said box (2) for detecting removal of said box (2) from the object of theft prevention based on information from said attached state detecting device (3, 103), and outputting an alarm in time of detection of the removal, a battery (V) mounted in said box (2) for driving said alarm output means (G), and a power supply switch (6) for turning power supply on and off between said battery (V) and said alarm output means (G). Consequently, by turning off the power supply switch, the theft preventive apparatus, even in a non-use state, does not start operating inadvertently by vibration or the like, thereby avoiding wasteful consumption of battery power.

The present invention relates to a detector for theft prevention used in contact with a commodity or the like exhibited in a shop.Conventionally, an operated portion for contacting a commodity or the like is pivotable only in one direction from a projected position. The commodity or the like cannot be moved in directions requiring the operated portion to pivot in directions other than that direction. A forcible movement would damage the operated portion.In a detector for theft prevention of this invention, a switch (3) provided for a box (2) thereof has a pivotable operated portion (3a) biased to return to a position projecting from a surface (2c, 2d) contacting an object of theft prevention (E). The operated portion (3a) is pivotable in a plurality of directions including at least two opposite directions (e1, e2). The detector for theft prevention is properly operable for movements in varied directions of the object of theft prevention (E).

A radio wave receiving signaling device includes an antenna (22) having a coil (22a). An electrically capacitive buzzer (21) is activated by alarm output device (AO) to generate sound when the receiving antenna (22) receives a sound generation instructing signal. The buzzer (21) and all or part of the coil (22a) of the receiving antenna (22) are connected to form a booster circuit to raise a voltage to be applied to the buzzer (21) by a resonance function.

A theft preventative apparatus is used to detect an attempted theft of an object and produce an audible alarm when an antenna (22) in the apparatus receives a radio wave signal from a transmitter (0). The apparatus can be deactivated using a bar-like releasing tool (K) inserted into the housing. Attempted theft can also be detected using a length of electrically conductive wire (3) securable to the object to be protected. The ends (30) of the wire are mounted to the housing. Disruption of the electrical path, such as by cutting the wire or removing one of the ends (30) from the housing, causes the audible alarm to be produced.

The present invention relates to a theft preventive apparatus to be attached to an object of theft prevention for detecting a preliminary stealing act by e.g. issuing alarm, and relates also to a radio wave receiving signaling device to be used with the apparatus. Conventionally, there has been a problem of the alarm output means being rendered inoperative when a sudden shock is applied to the theft preventive apparatus for example. According to the present invention, a circuit board (6) of alarm output means (AO) disposed inside a box (2) to be attached to the object of theft prevention is retained to one first side wall portion (2a) of a pair of opposed wall portions (2a), (2c) of the box, and the other side second wall portion (2c) retains a first-kind constituting element (FE) of the alarm output means (AO). A power-supply contact member (CE) formed integrally with the first-kind constituting element (FE) is adapted to contact a first-kind contact (FC) having a contact face extending toward the second wall portion of the circuit board (6). And, the power-supply contact member (CE) is comprised of a coil spring which can expand and contract in the approaching/departing direction of the pair of wall portions (2a), (2c) and which is disposed under a state contracted from its maximally expanded state. Then, the electric contact may be maintained against sudden shock.

A metal gasket 10 includes a pair of bead plates 14 and 14 having a cylinder hole 12 corresponding to a cylinder bore, a full bead 22 surrounding the cylinder hole, a first intermediate plate 18 interposed between the pair of bead plates, and a shim plate 16 interposed between the first intermediate plate and one bead plate in an area around the cylinder hole. The shim plate 16 is disposed to overlap with the full bead 22, and the thickness of a contact portion 19 to contact with the shim plate 16 of the first intermediate plate changes in the peripheral direction of the cylinder hole.

A client transmits, to a server, an instruction to copy a certain file for update, and receives the copied file. Upon update of the received file, the client generates update information on the update of the received file, and transmits the generated update information to the server. The server extracts a file containing a part related to the received update information, and judges whether or not the extracted file has been copied and then transmitted to a different client. If judging that the extracted file has been copied and transmitted to the different client, the server transmits warning information to the different client to which the extracted file has been transmitted, the warning information indicating that the file is updated in the client other than the different client.

When a vehicle collision is detected, a electric connection between a power supply and an input stage of an inverter is switched to the disconnected condition. Then, when a rotation speed of an alternating current motor is higher than an allowable rotation speed or a terminal voltage of a storage unit provided at the input stage is higher than an allowable terminal voltage, an exciting current command value is set at a value other than zero and a torque current command value is set at zero, and when the rotation speed is equal to or lower than the allowable rotation speed and the terminal voltage is equal to or lower than the allowable terminal voltage, both command values are set at zero. An exciting current component and a torque current component of an alternating current supplied from the inverter to the motor are controlled according to the set command values.
