Filed: 2001-12-28
Granted: 2003-06-21
Abstract: This invention provides a double cutting-edge bolt grooving machine, for forming grooves at a bottom face of a bolt. The grooving machine uses a rail to convey bolts. An intermittently rotating indexing tray is used to support the bolts that have been conveyed and then transporting the bolts to a designated location to pause for a period of time, during which period a presser presses against the screw cap and a grooving mechanism forms grooves on the bottom face of the bolt. The grooving mechanism includes a stationary base located next to the indexing tray, a swing base pivoted to the stationary base and reciprocally swingable forwards and backwards during the pausing period, a rotary base rotatably mounted above the swing base, two tool bases assembled to the rotary base to approach the bottom end of the bolt alternatively, and tools mounted to ends of the tool bases and rotating in opposing directions. As such, the tools are able to alternatively cuts grooves at the bottom face of the bolt when the swing base swings forwards and backwards to drive the rotary base for forming the grooves in a forward and backward direction to thereby reducing the possibility of bits being clogged in the grooves.

Title: Semiconductor memory and method of driving semiconductor memory
Inventor: KAWAMURA SHOICHI
IPC: G11C16/04
Filed: 2002-01-30
Granted: 2003-08-11
Abstract: During a period in which data write to a memory cell is performed, a positive voltage (a voltage substantially 1/2 the power supply voltage or more, and lower than the power supply voltage) is supplied to a line (memory cell source line) for supplying a reference potential to the memory cell. Even if a bit line and the memory cell source line are short-circuited, the potential of a node in a latch buffer unit is maintained at least during a period in which this node and the bit line are electrically connected. Since this makes it possible to determine that a program operation is normally performed and to complete a program verify operation, a defect caused by the short circuit between the bit line and the memory cell source line can be repaired by using a redundancy circuit.

Abstract: An instruction value is added to a specific signal to obtain an added signal. Motor is driven based on this added signal. Response of the motor is measured while the motor is being driven. A characteristic value calculated based on the response is compared with a reference value. When the characteristic value is significantly smaller than the reference value, the amplitude of the specific signal is changed so that the characteristic value converges to the reference value. When the characteristic value has almost converged to the reference value, frequency characteristics can be identified accurately.

Granted: 2006-08-21
Abstract: A user's handwritten signature data is transmitted to a host device, when the user registers his or her signature. A signature information controlling unit reads the codes of a character string of a font closest to handwriting shape data by referencing a signature dictionary information unit, extracts a predetermined number of digits of numeric values from the codes, generates a user ID by making the numeric values successive to the number of codes, and registers this user ID and the input handwritten signature to the signature dictionary information unit by making a correspondence between them. When a signature is authenticated, a user ID is automatically generated from a handwritten signature input by a user, and checked between generated user ID and registered user ID.
