A scanner apparatus and an image recording apparatus are provided with an array-like light source. A plurality of laser beams emitted from a semiconductor laser array are collected into a limited space region by a field lens, and an optical element integral with an image forming lens and a Fourier conversion element is arranged in the space region to form the plurality of laser beams into beams having a light intensity distribution of a Bessel-Gaussian type on a photosensitive drum.

A semiconductor laser array emits a plurality of laser beams. A polygon mirror deflects the plurality of laser beams together. A prism type reflector separates the deflected laser beams to different directions that are generally along an arrangement direction of a plurality of photoreceptors. The separated laser beams are input to the respective photoreceptors through mirrors and cylindrical lenses.

A finite state automaton (FSA) text search apparatus converts each of successively received binary code numbers, representing successive characters of a text to be searched, into two portions. Two portions are extracted from a state number which is currently being read out from a first table memory, with one portion being combined with one of the input character portions and the combination used to select one of a set of 1st displacement numbers from a second table memory, while a second portion of the current state number and the other portion of the input character number similarly select one of a set of 2nd displacement numbers from a third table memory, and the entire current state number selects one of a set of base numbers from a fourth table memory. The selected 1st and 2nd displacement numbers are combined with the selected base number, and the result used to select the next state number from the first table memory. The overall memory capacity required is minimized, while achieving a high search speed.

Disclosed is an absolute value comparator for comparing respective absolute values of sequentially applied two data. A decoder circuit sequentially converts the applied data into a plurality of bit signals in accordance with a predetermined rule. After a preceding conversion bit signal is once held in a register circuit, the held bit signal is inverted for each bit by an inversion circuit. Thus, a logic circuit receives a preceding inverted bit signal and a succeeding conversion bit signal and outputs an output signal B indicating the result of comparison. Since a full adder is unnecessary, a comparison between the absolute values of the applied data can be made at a high speed.

A rehabilitation training device and method in which a target heart rate is input, the heart rate is measured and a load in an ergometer operated by the person undergoing rehabilitation is changed accordingly. There are four steps in the training: (1) warm up--the load is increased to have the heart rate linearly approach the target value; (2) automatic--the load is varied to maintain the heart rate at the target; (3) interval--the load is alternated between its average value in the automatic step and a fraction thereof, and (4) cool-down-the load is gradually decreased.

In a semiconductor device, an active region includes: a first impurity region to which a predetermined voltage is applied; second and third impurity regions forming a pair of conductive electrodes of an insulated gate field effect transistor; and at least one impurity region disposed between the first and second impurity regions. A voltage that causes electrical conduction between the second and third impurity regions is applied to a gate electrode disposed between the second and third impurity regions. All gate electrodes disposed between the first and second impurity regions are configured to be electrically connected to the first impurity region constantly. All impurity regions disposed between the first and second impurity regions are electrically isolated from the first and second impurity regions and maintained in a floating state.

A detecting device includes a detecting unit that detects an image on a medium transported in a transport path. The detecting unit includes a light emitter, a light receiver, and a light adjusting portion. The light emitter emits light toward the transport path in which the medium is transported. The light receiver receives reflected light of the light emitted from the light emitter. The light adjusting portion adjusts a quantity of light received by the light receiver according to a quantity of light emitted from the light emitter.
