A diode has a semiconductor layer and cathode and anode electrodes on a surface of the semiconductor layer. The semiconductor layer has cathode and anode regions respectively contacting the cathode and anode electrodes. The anode region has a first diffusion region having high surface concentration, a second diffusion region having intermediate surface concentration, and a third diffusion region having low surface concentration. The first diffusion region is covered with the second and third diffusion regions. The second diffusion region has a first side surface facing the cathode region, a second side surface opposite to the cathode region, and a bottom surface extending between the first and second side surfaces. The third diffusion region covers at least one of the first corner part connecting the first side surface with the bottom surface and the second corner part connecting the second side surface with the bottom surface.

A scope unit 2 including a control unit 3 and an insertion portion 4 is attached to a main unit 1 via a scope connector 5. An optical adaptor 8 is attached to a tip of the insertion portion 4. The CCD 31, HICs 32, 33, and the thermistor 34 are attached to the tip of the insertion portion 4. A liquid crystal module 36 is attached to the optical adaptor 8. A barrier circuit 64 limits energy supplied to these components in a circuit disposed in the scope unit 2. By disposing the barrier circuit 64 in the scope connector 5, the portion extending from the barrier circuit 64 to, i.e., the control unit 3, the insertion portion 4, and the optical adaptor 8 are of the explosion-proof construction. Thus, these can be used in a hazardous explosive location. Thus, an endoscope apparatus that can be used in combustible gas or dust can be provided.

A base station includes a multicast group administration unit administering a multicast group to which a mobile station belongs, a timing determination unit determining an inter-frequency measurement timing when the mobile station measures a signal having a frequency different from a frequency for a residing cell of the mobile station, and a transmission unit transmitting data. The timing determination unit assigns an uniform inter-frequency measurement timing for at least two mobile stations belonging to the same multicast group. The transmission unit transmits data to a mobile station within the multicast so as to avoid the inter-frequency measurement timing.

The mobile terminal apparatus of the present invention includes a housing having an opening section in which an accommodated object is fitted; a lid covering the opening section, the lid having a protrusion which surrounds the opening section and shields the accommodated object from water, on a surface facing the accommodated object; and a cover covering the lid, the cover being attached to the housing to press the lid onto the housing. When the cover is attached to the housing, the protrusion of the lid surrounds the opening section and is pressed onto the housing by the cover, so that the accommodated object can be reliably shielded from water.

An audio device has controls for setting parameters. In the audio device, a selection mode setting part sets a selection mode in which a parameter to be stored is selected. A position acquisition part acquires positions of the controls and locks setting states of the parameters that are set by the controls, when the selection mode is set by the selection mode setting part. A parameter selection part detects one or more control operated by a user among the controls and selects each parameter corresponding to each operated control among the controls as a parameter to be stored, after the setting states of the parameters are locked by the position acquisition part. A reset part returns positions of the controls to the positions acquired by the position acquisition part and memorizes a selection status of each parameter which indicates whether each parameter is selected or not, when the selection mode is completed.

A method for determining feature point locations in an image performs a first search in a predetermined first search area to search for locations of plural feature points in the image, corrects the locations of the plural feature points based on a geometric layout relationship among the plural feature points searched for, sets a second search area based on the corrected location of each of the feature points, and performs a second search in the second search area to search for the location of each of the feature points. Then, the method determines reliability of the location of each feature point searched for by the second search and selects one of the corrected location and the location searched for by the second search, as a location of the feature point.

An electric power steering system includes a multi-phase electric motor, an inverter connected to the rotary electric machine and an electronic control apparatus. One phase of the motor is pulled up by a resistor. The electronic control apparatus detects disconnection abnormality between the motor and the inverter by checking phase voltages of the inverter by stopping the inverter operation. If disconnection is detected, current is supplied to the remaining normal two phases. The electronic control apparatus detects short-circuit abnormality by checking an electric angle (rotation angle) of the motor.

Drawing methods and drawing furnaces for drawing an optical fiber with small non-circularity by simple drawing system are provided. An optical fiber preform is received into a muffle tube and heated by a primary heater placed to surround the muffle tube. The optical fiber preform is heated such that a starting position of a meniscus portion is higher in its position than the top of the primary heater, wherein the meniscus portion is created at the bottom portion of the optical fiber preform.

An apparatus extracts a first dictionary information associated with a first category from among multiple categories included in a dictionary and second dictionary information associated with a second category from among multiple categories included in the dictionary or another dictionary, calculates a first feature amount and a second feature amount from the first dictionary information and the second dictionary information, respectively, receives an instruction as to whether or not to integrate a name of the first category and a name of the second category in the case where it is determined that a similarity between the calculated first feature amount and second feature amount is greater than a predetermined threshold and that the name of the first category and the name of the second category do not match, and integrates the name of the first category and the name of the second category with the received post-integration name.
