Abstract: A sensor system includes a sensing element, an illumination optical system including a light source, the illumination optical system being configured to obliquely illuminate the sensing element, and a detector device configured to detect light reflected off the sensing element. The sensing element includes a chemical sensing layer configured to change in an optical characteristic in response to contact with a target substance, a reflection layer configured to reflect at least part of incident light, and an intermediate layer located between the reflection layer and the chemical sensing layer. The detector device is configured to separately detect p-polarized light and s-polarized light reflected off the sensing element.

Abstract: An optical detection type chemical sensor includes a light source, a detection element and a photodetector. The detection element is constituted of a laminate in which a multilayer film including a chemical detection layer, an optical interference layer, and a half mirror layer is formed on a transparent substrate. At least one of the layers includes a magnetic material. Light from the light source is applied to the detection element under the condition that the light enters inside of the detection element from the rear surface of the transparent substrate on which the laminate is not formed and multiple reflection occurring in the laminate intensifies the magneto-optical effect. A subject is detected by using the photodetector to detect a magneto-optical signal indicating a change in reflected light from the laminate resulting from a change in an optical property resulting from a reaction in the chemical detection layer.

Abstract: A magnetic head is constituted by depositing two return yokes, and two coils to sandwich a main pole on a substrate, polishing an end surface extending in a deposition direction to form an opposite surface, and forming an auxiliary yoke in the opposite surface. The auxiliary yoke has a rectangular opening for exposing a tip surface of the main pole to the opposite surface. An end surface of the opening faces the main pole in noncontact therewith through a predetermined gap.

Abstract: A video tape recorder monitors the signal immediately after it has been recorded to determine whether errors have occurred in the recorded signal rerecords the video signal in the same location in the tracks where the error occurred. The location requiring rerecording can be located by recording a time code along with the video signal as it is recorded and rewinding the tape to the location where the error occurs and recording a stored video signal at that location or the video signal can be delayed and rerecorded downstream using another recording head once an error has been detected using an error detector.

Abstract: In a video tape recorder, recording and reproducing heads record and reproduce a recording signal on recording tracks which are diagonally formed one after another on a tape-like recording medium. The recording heads are capable of recording again the same recording signal in the same recording region. If a recording error occurs during recording mode, information on where the recording error has occurred and a recording signal to be recorded are stored in a memory. During rerecording mode, the stored information is used to complement the recording error. If a recording error occurs, preliminary recording circuitry operates so as to complement this recording error. The above construction permits the recording signal to be recorded on the recording tracks with certainty.

Abstract: A planar thin film magnetic head is disclosed wherein an axis of easy magnetization in the vicinity of a magnetic gap of a magnetic yoke is forcibly made coincident with the direction of a track width by a magnetic field due to current flowing in a conductor layer. Accordingly, even though the track width is small, a high magnetic permeability, low Barkhausen noise and linear responsiveness can be realized to thereby improve the sensitivity, output and linearity. In another aspect of the invention, a throat portion is eliminated from a thin film magnetic core forming a magnetic gap. The thin film magnetic core is configured such that a pair of magnetic members constituting the magnetic core are diverged from the magnetic gap so that a divergent angle .theta., of first opposite side edges of the magnetic members, from a direction of the gap length of the magnetic gap, is set to the range of 30.degree..ltoreq..theta..ltoreq.80.degree.

Abstract: In an electronic control system having a main CPU and a slave CPU which is under the control of the main CPU, a power control circuit is provided between the power source and the slave CPU to stop supplying power to the slave CPU until the main CPU starts normal operation when the power to the overall system is turned on. The slave CPU does not start operation until the main CPU becomes capable of normal operation and control over the slave CPU, which prevents unexpected action of the slave CPU and the subordinate control object. The power control circuit is also effective in preventing the abnormal action of the slave CPU when the power to the overall system is turned off.

Abstract: A typewriter having an automatic erasing function, having an erasing device responsive to an erasure-start key, for effecting an erasing operation to successively erase the characters printed by a printing device, and a controller responsive to the erasure-stop key, for permitting the erasing device to interrupt the erasing operation. The typewriter has an input buffer for storing input data which is entered through a keyboard while the erasing device is operated, the typewriter. The typewriter may be arranged so that the input buffer is cleared upon operation of an erasure-stop key. The above arrangement may be adapted to erase successive words on a display device as character and space data are retrieved from a memory. In this case, a device may be provided to suspend a continuous erasing operation for a predetermined time each time the space data representative of a space between the words has been retrieved from the memory after at least one character has been erased.
