A paper feeding unit includes: a detecting board formed of a regular-polygonal prism having a multiple number of sensors; a detection block with sides which each have a multiple number of signal generating portions and are able to face the sensors; a holder portion holding the detection block so as to allow the posture of the block to be changed to fix the block at setup positions; and a display window which allows a paper-size indicator displayed on the signal generating portions of the detection block to be seen from the outside. In this configuration, the orientation and position of the detection block are adapted to be changed in accordance with the size of paper held in the paper feed cassette.

A vertical spindle duplex head for a grinder includes an annular pressure wheel and a receiver wheel arranged to rotate and revolve workpieces between the annular surfaces of the pressure wheel and the receiver wheel and a grindstone for one end portion of the workpieces driven in the opposite directions of rotation of the pressure wheel and receiver wheel and at their different rotational ratios. The workpieces rotate and revolve between these wheels, thereby grinding their end face by means of a grindstone arranged around the external periphery of a rotary carrier.The pressure wheel and receiver wheel are rotatably driven in opposite directions and at their different rotational speeds by distributing driving force from one source to each of them and a variable driving means is provided on one of the transmittance routes of the driving force extending from the place of distributing the driving force to both of the pressure wheel and the receiver wheel, whereby the rotational ratio of each of them can be optionally changed.

Provided herein is a lead-acid battery for which the risk of breakage of a current collecting lug part of a plate while in use is eliminated by simple means. At least a positive plate group of the lead-acid battery includes: one or more plates each including a current collector having a current collecting portion formed by expanding or punching a lead alloy sheet manufactured by cold rolling, and one or more current collecting lug parts unitarily formed with the current collecting portion; and a strap formed by a cast-on strap casting method and coupled to the one or more current collecting lug parts. The current collecting lug part is formed with an elongated protrusion extending in a direction away from the current collecting portion. The elongated protrusion continuously extends in a direction toward the current collecting portion of the plate from inside the strap.

According to one embodiment, a semiconductor device includes a processor, and a memory device. The memory device has a nonvolatile semiconductor storage device and is configured to serve as a main memory for the processor. When the processor executes a plurality of programs, the processor manages pieces of information required to execute the programs as worksets for the respective programs, and creates tables, which hold relationships between pieces of information required for the respective worksets and addresses of the pieces of information in the memory device, for the respective worksets. The processor accesses to the memory device with reference to the corresponding tables for the respective worksets.

In a saddle-riding type vehicle including a shroud, efficiency is achieved by disposing a vehicle component in a space shielded by the shroud, and the vehicle component is suitably protected from, for example, rainwater, while ventilation for the vehicle component is ensured. A regulator is disposed on a first side of the vehicle, at a position at which the regulator does not overlap a fuel tank as seen in a top plan view. The regulator is covered by a right shroud from above and from outside in the vehicle width direction. The right shroud has an opening formed therein at a portion where the regulator faces upwardly. The opening overlaps with, and is covered by from above by part of the right shroud that is different from the portion of the right shroud at which the opening is formed in a top plan view.

An air-fuel ratio control apparatus for an internal-combustion engine includes an air-fuel-ratio sensor, a control-input calculator, an air-fuel-ratio controller, and a gain calculator. The air-fuel-ratio sensor is disposed in an exhaust channel in the internal-combustion engine and is configured to detect an air-fuel ratio in exhaust gas. The control-input calculator is configured to calculate a control input in accordance with an output value of the air-fuel-ratio sensor. The air-fuel-ratio controller is configured to perform a feedback control using the control input such that the output value of the air-fuel-ratio sensor reaches a target value. The gain calculator is configured to calculate a gain in accordance with the output value when the output value is leaner than the target value. The gain is to be used in calculating the control input.

A regenerator, for use in a heat engine, configured to receive and store heat from a high-temperature gas flowing from a high-temperature space into the regenerator, and to provide the heat to a low-temperature fluid flowing from a low-temperature space into the regenerator. The regenerator includes a large number of layered metal meshes. Each metal mesh includes a large number of mutually parallel longitudinal strands and a large number of mutually parallel lateral strands perpendicular to the longitudinal strands. The metal meshes are layered such that each metal mesh is sequentially rotated in a same direction by a fixed angle with respect to an immediately previously layered metal mesh.

A plant controller includes a feedback controller configured to calculate a control input provided to a plant so that a control output of the plant matches a target value. The feedback controller includes a controller transfer function that is a transfer function of the feedback controller. The controller transfer function is expressed by a product of an inverse transfer function of a transfer function of a control target model obtained by modeling the plant and a disturbance sensitivity correlation function defined using a sensitivity function. The sensitivity function indicates sensitivity of a disturbance to be applied to the plant with respect to the control output. The sensitivity function is defined by using a response characteristic parameter that indicates a response characteristic of the plant.
