Title: Input signal reading circuit having a small delay and a high fidelity
Inventor: SUTO SHINICHI
IPC: H03K5/1252
Filed: 1997-11-10
Granted: 2001-04-10
Abstract: An input signal reading circuit comprises an up-down counter receiving an input signal and a sampling clock to count up the sampling clock when the input signal is at a high level and to count down the sampling clock when the input signal is at a low level. The up-down counter outputs an underflow signal when a count value of the up-down counter becomes zero. A comparator compares the count value of the up-down counter with a reference value held in a register, to generate a coincidence signal when the count value of the up-down counter becomes coincident with the reference value. A RS flipflop is set by the coincidence signal to bring the read-out signal into a high level, and is reset by the underflow signal to bring the read-out signal into a low level.

Abstract: A new two-dimensional (2D) variation modeling and control technique for a machine producing a web of material, such as paper, uses functional transformation with basis functions which are wavelets, preferably wavelets derived from and closely resembling the responses generated by actuation of cross direction (CD) actuators of the machine. By using the disclosed functional transformation together with carefully selected basis functions, memory and real-time processing requirements are substantially reduced so that practical controls can be readily implemented. In addition, the functional transformation technique of the present application expands conventional CD  correction to also correct for a portion of the residual variations which, until now, have remained uncorrected. The new 2D profile is treated as the superposition of two main components: a pure machine direction (MD) variation component and a two-dimensional sheet variation component.

Abstract: A storage holster designed to securely contain and provide easy access to a release pull bar that is used for unlocking a fifth wheel assembly of a transport truck. The holster comprises an elongated rectangular plate with a carrier projecting from one side of the plate. The carrier receives and supports a release pull bar and has an open end which commences at a point midway along the longitudinal axis of the plate. The closed and of the carrier terminates at the distal end of the plate and is provided with one or more holes to permit drainage of grease or oil that may be coated on a pull bar following use thereof. A pin, inserted through a hole in both the carrier and plate, works in combination with a padlock to function as a security and safety device to prevent the pull bar from being removed without authorization, or from maneuvering out of position when the truck is in transit.      Connected near the proximal end and on the same side of the plate is a narrow rectangular collar lined with a rubber grommet. The collar helps to stabilize the position of a release pull bar during storage and prevents it from vibrating in the holster during transit. The invention also provides a means with which to attach the holster to a support surface of the truck, generally in an upwardly angled orientation to permit insertion and retention of a pull bar.
