摘要:
A mechanism for mounting a storage device such as a magnetic disk device to a terminal device, capable of simplifying the attachment/detachment of the storage device, requiring a smaller number of parts for the attachment/detachment and preventing external shock from reaching the storage device. Storage devices are mounted to a frame made of a flexible material such as resin which, in turn, is fastened to a terminal device, without screws, by inserting a portion of the frame into a hole on the terminal device. Means made of a flexible material are provided on the upper surface of the frame for fastening the storage devices for absorbing the external shock or vibration by the elasticity thereof.

The vehicle navigation system suggests route to a destination and repeats searching for a new optimal route in response to changes in traffic conditions near the present position of the vehicle. The system includes a present position calculator 4A for calculating the present position of the vehicle, an information storage unit 3 for storing road data 3B for searching, a traffic information receiver 4F for acquiring traffic information 5, a route searcher 4B for searching for the optimal route from the present position to the destination based on a navigation program 3A, the road data, and the acquired traffic information, and an area setter 4C for setting a given range near the present position of the vehicle, whereby the route searcher selects and acquires traffic information corresponding to the road data within the set area, and searches for the optimal route by first changing road data based on the acquired traffic information.
摘要:
A method for restoration of a cavity of a tooth including firmly bonding a tooth and a dental composite resin by using a resin reinforced type glass ionomer cement. The method includes a step where the cavity of the tooth is treated with a tooth surface treating agent containing an aqueous solution of acid as a main component or a pre-treating agent containing an unsaturated organic compound as a main component; a step where the resin reinforced type glass ionomer cement is filled in or spread to the cavity; a step where a dental composite resin is then filled in the cavity before or after the resin reinforced type glass ionomer cement is hardened; and a step where the dental composite resin is hardened.
摘要:
A tooth-surface treatment agent for use with dental glass ionomer cement comprises (a) a polymer of an .alpha.-.beta. unsaturated carboxylic acid having a specific molecular weight, (b) a compound containing one or more of the elements selected from the group of aluminum, iron, tin, and calcium, and (c) water. This agent ensures the dissolution and removal of the smear layer, and improves and stabilizes the bonding strength of the glass ionomer cement to tooth structure. Also, the agent has a milder effect than the effects had by phosphoric acid, and has an action on reducing irritation to the dental pulp and is harmless thereto because it enables the smear plugs to remain in dentinal tubules.

A color cathode ray tube includes an electron beam generating source, a first accelerating electrode, a focus electrode, and a second accelerating electrode, for focusing an electron beam onto the phosphor screen. The length of the focus electrode is equal to or larger than two times the diameter of the main lens, and the highest voltage is applied on the first accelerating electrode and the second accelerating electrode, and a voltage lower than the highest voltage is applied on the focus electrode, and the length of the first accelerating electrode is within the range from about 0.4 to 2 times the diameter of the electron beam passage aperture formed in the surface of the first accelerating electrode on the side of the electron beam generating source.

An electron beam measuring apparatus for measuring size of pattern on surface of a specimen comprising, an electron gun, an electron lens for focusing the electron beam from the electron gun on the specimen surface, a deflector for deflecting the electron beam, a spot control means for forming a flat edge portion in the electron beam spot, a rotation coil for rotating the electron beam so that the flat portion of the electron beam spot becomes to be perpendicular to the scanning direction of the electron beam, a detecting means for detecting secondary electrons reflected from the specimen surface, and a computer for calculating the size of the pattern based on the secondary electrons from the detecting means. As the flat portion of the electron beam spot is perpendicular to the scanning direction, the size of pattern is measured with high accuracy.
摘要:
When an insert portion of an endoscope main body is inserted into a blood vessel of a patient and an observed image in the blood vessel is recorded by an image recording unit such as a TV camera and a video tape recorder, the image observed by the endoscope main body is detected by a red-only detector. When it is confirmed that a field of view in the blood vessel can be assured in accordance with a detection result of the red-only detector, the image recording unit is turned on. When the field of view cannot be assured, the image recording unit is turned off.

A camera device for an endoscope comprises a character display section for displaying data relative to an endoscopic image, and drive motors for film winding and shutter drive. The camera device further comprises a sensor for detecting a residual film quantity corresponding to a predetermined number of frames or less, a sensor for detecting the film end, and sensors for detecting a malfunction of the drive motors. Detection data detected by these sensors are displayed by the display section.

Herein disclosed is a heat resisting electrical connector assembly which has a heat resisting metallic locking clip. The locking clip is detachably fixed to a female part of the connector assembly and comprises a first portion lockably fixed to the female part, a second portion having a locking opening formed therein and a third portion having a free end, the third portion being resiliently moved together with the free end thereof toward the first portion when pressed toward the first portion. A male part of the connector assembly is formed with a projection with which the locking opening of the clip is engaged upon final coupling of the male and female parts. A fulcrum structure is formed on the female part to support partially the third portion of the clip in such a manner that when the third portion is pressed toward the first portion, the second portion is raised away from the first portion thereby disengaging the locking opening of the clip from the projection.
摘要:
The photosensor is provided with a light-receiving surface for receiving a reflected image of an object and in which an aperture is provided. The aperture is positioned so as to receive a focused image and means are provided to prevent light from leaking directly to the light-receiving surface from the aperture. Prevention of light leakage permits focusing to be detected at high precision.
