Abstract: This invention relates to a lock, which includes a housing and an indicative lock core. The indicative lock core is operable by a key to move to an indicative position and be stuck in the indicative position. The indicative lock core can move back to its original position only through a restore mechanism. When the key-operated lock core is in the indicative position, the key-operated lock core is partly situated outside the housing and is easily noticed.

Abstract: A strap lock includes a first snapping member, a second snapping member, a strap, a stop member and a locking mechanism.

Abstract: In a real time clock having a register, a preinstalled central processing unit issues a control instruction to hold a time stamp of an external register in the real time clock and then reads the time stamp of the external register, if a server or a control end needs to read the time stamp of the real time clock. The real time clock having a register is comprised of a timing generator for generating a time stamp that is stored in the external register and a controller for controlling the timing generator and the external register. The preinstalled central processing unit can read the time stamp stored in the external register, so as to accurately read the time of issuing a read command given by the central processing unit, regardless of whether or not the preinstalled central processing unit is situated in a busy state of executing other programs.

Abstract: A baggage fastening device includes a first snapping member, a second snapping member detachably secured on the first snapping member, a strap mounted between the first snapping member and the second snapping member, and a protruding stop member mounted on the first snapping member and extended to a side of the second snapping member. Thus, the stop member restricts movement of the strap, so that the movable portion of the strap cannot be released and moved backward after the baggage is tightened by the strap, thereby preventing the strap from being loosened from the baggage so as to provide an anti-reverse effect to prevent the baggage fastening device from being loosened from the baggage.

Abstract: A lock device includes a housing, a locking mechanism, and a shielding section located between the housing and the locking mechanism. The shielding section and at least part of the housing together define a restricting space. When the locking mechanism is set to a locked state relative to the housing, the shielding section is located at a position closing the restricting space, and when the locking mechanism is set to an unlocked state, at least part of the shielding section is displaceable relative to the housing to open the restricting space.

The indicator is in a third position when the locked core is in the releasing position.

Abstract: A lock for an electronic apparatus includes a housing, a snapping member, a control member, a locking mechanism, and a cable. Thus, the electronic apparatus is locked by the lock so as to attach the electronic apparatus to a fixing body by the lock so that the electronic apparatus is limited to move in a determined field so as to achieve an anti-theft purpose. In addition, the plug of the snapping member is directly inserted into the slot of the electronic apparatus to lock the electronic apparatus, so that the lock is operated easily and conveniently, thereby facilitating the user locking the electronic apparatus by the lock.
