Abstract: A heat gun includes a canister, a first outlet pipe, and an assistant member. The canister includes a columnar sidewall bounding a receiving space and an installation board mounted in the receiving space. The assistant member includes a first vent pipe, and a second vent pipe communicating with the first vent pipe and slidably mounted to the first vent pipe. Top ends of the first outlet pipe and the first vent pipe extend through the installation board and communicate with an upper portion of the receiving space. Bottom ends of the first outlet pipe and the second vent pipe function as outlets of the heat gun.

Abstract: A draining apparatus for a keyboard of an electronic device includes a base for slantingly supporting the keyboard and a protecting film to be covered on the keyboard. The protecting film includes a waterproof sheet and a flange protruding up from edges of the waterproof sheet. The flange defines an outfall adjacent to a bottom end of the flange. In case liquid is spilled on the protecting film, the water may flow downward and islet out through the outfall.

Abstract: A paper sheet management apparatus includes: a serial number recognizing unit 38A that performs a character recognition of a serial number of predetermined digits for recognizing a banknote from the banknote, obtains a character recognition result including a recognizable character and/or an unrecognizable character, and obtains a serial number recognition result including a recognizable determined character and/or an unrecognizable error character based on the obtained character, recognition result; a serial number registration condition processing unit 38B that judges whether the serial number recognition result meets a predetermined registration condition based on the determined character or the error character in the obtained serial number recognition result; and a DB control unit 38E that registers banknote detailed information including the serial number recognition result in a database 33, when the serial number recognition result meets the predetermined registration condition, and forbids registration

Abstract: A paper sheet recognition apparatus, a paper sheet management apparatus, and paper sheet recognition method for performing recognition process for the paper sheets such as banknotes, checks, bills and exchange coupons, wherein image data of the paper sheets are acquired, and identification data that is printed on the paper sheets to identify the paper sheets uniquely are extracted in accordance with the acquired image data, while managing the identification information extracted correspondingly to the registration numbers marked on the paper sheets and the acquired image data, thereby allowing to precisely identify whether or not the paper sheets are judged to be legitimate bills by the paper sheets recognition apparatus.

Abstract: A circuit for testing a buzzer includes a microphone, an amplifier circuit, a microprocessor circuit, and a display circuit. The amplifier circuit is configured to amplify an analog signal from the microphone to an amplified signal. The microprocessor circuit determines whether a loudness and a frequency of the amplified signal are within proper ranges. The buzzer is qualified if the loudness and frequency of the amplified signal are within the proper ranges. The display unit displays the loudness, the frequency, and a test result.

Abstract: A control circuit for a display device includes a group of keys, a video graphics array (VGA), and a control unit. The VGA port is electronically connected to the display device via a VGA bus. The control unit is electronically connected to the group of keys, and is electronically connected to the VGA port via an inter-integrated circuit (I2C) bus. The control unit outputs control signals when at least one key is actuated, and then the control signals is transmitted to the display device via the VGA port.

Abstract: A multimedia projector includes a local area network (LAN) port, a storage system, a video playing module, a file activation module, and a projection lens. The LAN port is coupled to a peripheral apparatus to receive videos and files from the peripheral apparatus. The storage system stores the videos and the files. The video playing module reads the videos from the storage system, and plays the videos. The file activation module reads the files from the storage system, and opens the files. The projection lens projects the videos and the files accordingly.

Abstract: A drive circuit is used in an electronic device comprising multiple peripheral component interconnect-express (PCIE) slots. The drive circuit includes a motherboard, a first signal generation circuit, a second signal generation circuit, and a first delay circuit. The motherboard provides a control signal to the first signal generation circuit and the first delay circuit. The first signal generation circuit outputs immediate drive signals to first multiple PCIE slots. The first delay circuit outputs a first delay control signal to the second signal generation circuit after a predetermined time. The second signal generation circuit outputs drive signals to drive second multiple PCIE slots.

Abstract: A paper sheet management apparatus includes a serial number recognition unit (37A) recognizing the serial numbers of all transaction banknotes, for each banknote transaction, a banknote transaction list information preparation unit (37F) preparing banknote transaction list information on the serial numbers of all transaction banknotes recognized by the serial number recognition unit (37A), and a print and output control unit (37G) printing and outputting a banknote transaction list, based on the banknote transaction list information prepared by the banknote transaction list information preparation unit (37F). With this configuration, the teller can present the banknote transaction list to the customer, and thus the teller and customer can respectively confirm the transaction content, based on the banknote transaction list, and clarify the source of each transaction banknote, i.e.

Abstract: A banknote management system 1 includes a banknote handling apparatus 2 having stackers for stacking banknotes, the banknote handling apparatus sorting the banknotes based on sorting conditions set for the respective stackers, and sequentially stacking the sorted banknotes in the stackers corresponding to the sorting conditions; and a banknote management apparatus 3 managing the banknote handling apparatus. The system includes a DB registration specifying unit 32B specifying a stacker 11 a DB registration necessity of which is specified among the stackers; a banknote detailed information creating unit 37B creating banknote detailed information for recognizing a banknote that is stacked in the stacker a DB registration of which is set to be necessary; and a DB control unit 37D registering the banknote detailed information in a database 33. The system can minimize a memory capacity of the database and a volume of banknote detailed information to be registered in the database.
