In the conventional semiconductor device, it is impossible for two CPUs to operate memories to be debugged at synchronous timings. According to one embodiment, the operation verifying program analyzes the operation verifying command received by the first semiconductor devicefrom the external deviceby its own device (S), transfers the operation verifying command to the second semiconductor device(S, S), also analyzes the operation verifying command in the second semiconductor device(S), outputs the trigger signal (S, S) to the first semiconductor devicefrom the second semiconductor devicebased on the result of the analysis, writes the memory setting values included in the operation verifying command to the memories in the respective semiconductor device (S, S) based on the trigger signal, and restarts the device operation based on the written memory setting values.

A control system for a work includes an operating device and a controller. The operating device outputs an operation signal indicative of an operation by an operator. The controller is in communication with the operating device. The controller determines a target profile of a terrain to be worked on. The controller generates a command signal to operate the work implement according to the target profile. The controller receives the operation signal from the operating device. The controller determines an operation of the work implement based on the operation signal. The controller corrects the target profile according to the operation by the operator when the operation of the work implement by the operator is performed.

In a semiconductor device according to the related art, unfortunately, a non-safety unit mounted on the same device as a safety unit is modified with low flexibility. According to one embodiment, a first semiconductor chip and a second semiconductor chip each have space domain separation hardware for limiting access to hardware resources in a functional safety system. Safety unit software and space domain and time domain separation software are executed in a time sharing manner. Based on a timer installed on the semiconductor chip, the space domain and time domain separation software performs separation for intermittently executing the safety unit software in a predetermined cycle, self-diagnosis for examining an operation of the safety unit software, and mutual diagnosis made between the first semiconductor chip and the second semiconductor chip to mutually diagnose the operation of the space domain and time domain separation software for performing the separation and the self-diagnosis.

A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move a work implement of the work vehicle along the design surface. The controller determines if slip of the work vehicle has occurred. Upon determining that slip has occurred, the controller changes the design surface to a position equal to or higher than a blade tip position of the work implement when the slip occurred.

A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move the work implement along the design surface. The controller determines if slip of the work vehicle has occurred. The controller raises the design surface when the blade tip of the work implement is positioned below an initial target surface when the slip occurs. The initial target surface is the design surface before the occurrence of the slip.

Pairs are formed from a plurality of dispersed volumes and copying between the volumes is conducted by a series of remote operations from a management server. A management serverinstructs the generation of configuration setting filesto host computersselected so as to form copy pairs. If the configuration setting files are generated by host agents, the management serverinstructs copy start to a host computerhaving a primary volume. The host agentgenerates a prescribed command via a copy pair control moduleand causes a storage subsystemto execute copying between the volumes. When copying is completed, the management serveracquires the newest storage configuration information from the storage subsystemand updates configuration information DB

An optielectronic device comprising a substrate crystal whose crystal plane is a (n11) plane tilted from the (100) plane toward the [110] direction, or [110] direction where (n&gt;1). When the substrate is applied to an AlGaInP semiconductor laser, the optical device can be cleaved into a rectangular shape, as in the case of a (100) substrate crystal, resulting in easy handling of the chips and also is effective for making the lasting wavelength shorter, lowering the threshold current density for lasing, improving the continuous lasing temperature, etc. Furthermore, semiconductor lasers of different lasing wavelengths can be prepared under good control. Furthermore, a doping efficiency having no dependence on a tilt angle can be obtained by proper selection of a dopant. For example, Si is suitable as an n-type dopant entering sites of group III atom on an (n11) A plane (n.gtoreq.2).

A high-power low-noise semiconductor laser device required for light sources for an erasable optical disc is a self-sustained pulsating semiconductor laser device in which an MQW structure is used for an active layer, and thus a kink output power and a light output power by which the self-pulsation is enabled are increased to 10 mW or more and noise is reduced. Another semiconductor laser device of a self-pulsation type has impurities that are doped in the active layer to reduce the self-pulsating frequency to obtain a low-noise characteristic even if higher optical feedback occurs. 259

Semiconductor laser device

Disclosed is a semiconductor laser wherein an interface layer is provided on an upper cladding layer formed on an active layer, the interface layer having a smaller Al mole ratio than that of the upper cladding layer, thereby preventing oxidation of the semiconductor surface which is exposed to the atmosphere, and thus improving the crystallizability of a semiconductor layer which is to be formed subsequently. By setting the refractive index of this semiconductor layer so as to be smaller than that of the upper cladding layer, light can be confined in the active layer at increased efficiency.
