Highly durable silica glass containing 0.01% to 2% by weight of at least one element selected from magnesium, calcium, strontium, barium, yttrium, hafnium and zirconium. The silica glass is produced by melting a powdery material comprising a finely divided silica powder and a finely divided zirconium-containing substance by oxyhydrogen flame or plasma are to form an accumulated molten material layer, and extending the molten material layer outwardly in radial directions.

A general-light observation light image can be obtained by illuminating the polarized frame sequence light or polarized white light, for example. In addition, a parallel polarized component and a vertical polarized component with respect to a polarizing direction of illuminating light, which is polarized in a specific direction are captured. Then, image data, which is a difference between both of the polarized component is calculated and is displayed in a display device. Thus, a scattered light component in a living-body tissue surface side can be extracted with good S/N, which can improve the diagnosis functionality.

An output circuit of a semiconductor memory device is made up of a level recognition circuit which outputs a feedback signal by comparing an output node and a second reference voltage, and a P-channel MOS transistor and an N-channel MOS transistor which complimentary turn on and off in response to the feedback signal. As a result, when a charge of the output node is not sufficient, the output node is charged by setting a voltage of a power supply node to a power supply voltage Vcc. Then, when the output node is sufficiently charged, the N-channel MOS transistor turns on, and as a result the voltage of the power supply node is set to a first reference voltage. Accordingly, the output circuit of the semiconductor memory device achieves an increased operation speed and decreased voltage level amplitude at the output node.

A service processing apparatus that is realized by a computer is provided. A service ID generating/adding component of the service processing apparatus generates a service ID including a call origin ID and a call destination ID, in each of which an ID element is set, and adds the generated service ID to a service request transmitted when no upper service processing apparatus to the own apparatus exists, and, when an upper service processing apparatus to the own apparatus exists, generates a service ID including a call origin ID in which is set an ID element set as the call destination ID in a service ID added to a service request received from the upper service processing apparatus and a call destination ID in which is set an ID element and adds the generated service ID to the service request.

Vehicle operation diagnosis devices, methods, and programs diagnose a driver's operation of a vehicle based on a vehicle parameter and a driving diagnosis judgment standard that is set for a diagnosis item. The devices, methods, and programs acquire information that pertains to an accident factor for a high-accident location in the vicinity of the vehicle where not less than a specified number of accidents have occurred in the past, modify the driving diagnosis judgment standard based on the accident factor for the high-accident location, in a case where the vehicle is traveling in the high-accident location, and acquire the vehicle parameter. The devices, methods, and programs diagnose the driver's operation of the vehicle based on the modified driving diagnosis judgment standard and the acquired vehicle parameter.
摘要:
An electromagnetic exciter includes a magnetic circuit assembly having an outer yoke, a magnet, and an inner yoke. A voice coil is inserted into a magnetic gap formed in the magnetic circuit assembly. A casing having a cylindrical wall is disposed around the magnetic circuit assembly. A suspension is set between a cylindrical side wall of the outer yoke and the cylindrical wall of the casing to supportingly connect the magnetic circuit assembly to the cylindrical wall of the casing. A weight is secured to the outer side surface of the side wall of the outer yoke. The suspension has an outer ring, an inner ring, and a pair of arcuate arms. Each arm is connected to the outer ring at one end thereof and connected to the inner ring at the other end thereof The arms and/or portions of the weight that face the arms are sloped so that the weight will not contact the arms when the magnetic circuit assembly is vibrated.

A vibrator has a cup-shaped casing, a substrate provided to close an upper end opening of the casing, a magnetic circuit assembly provided in the casing, a first suspension and a second suspension that support the magnetic circuit assembly from above and below, and a voice coil secured to the substrate and inserted into a magnetic gap in the magnetic circuit assembly. The first suspension has an inner fixed portion that is secured to the substrate and that has a radially inner ring-shaped portion and a pair of extensions extending radially outward from mutually diametrically opposing positions on the ring-shaped portion. The first suspension further has a pair of leaf spring portions arcuately extending from the respective extensions through an angle of about 270 ° in symmetry to each other around the axis of the voice coil. Further, the first suspension has outer fixed portions disposed at the distal end portions of the leaf spring portions and secured to the upper end surface of a weight of the magnetic circuit assembly.
