Title: Optical fiber with dielectric multi-layered film and its manufacture
Inventor: OGUCHI TAISUKE
IPC: G02B6/02
Filed: 1989-06-09
Abstract: PURPOSE:To vapor-deposit a film without damaging an adhesive at a terminal part thermally nor changing the composition of the vapor-deposited film by providing a dielectric multi-layered filter on the polished end surface of a terminal of an optical fiber, and forming the jacket of the optical fiber by using metal. CONSTITUTION:The dielectric multi-layered film filter 17 which is formed directly by an ion-assist vapor-depositing method is provided on the polished end surface of the terminal of the optical fiber with the dielectric multi-layered film which is formed of a structure member such as a ferrule 19, and the jacket of the optical fiber is made of metal. Consequently, the ion-assist vapor- depositing method by which the dielectric multi-layered film 17 with good sticking strength and high closeness is obtained without heating a substrate is used to prevent the adhesive used at the fiber terminal where the vapor deposition is performed from being damaged thermally, and the jacket of the fiber 13 is made of metal to evade the problem of gas produced from the jacket during the vapor deposition, thereby forming the dielectric multi-layered film 17 of good quality on the end surface.

Abstract: PURPOSE:To obtain an apparatus and a method which facilitates the measurment of an absolute value of the closest distance of a moving object from passive sensor information to receiving a sound wave radiated from the moving object under water. CONSTITUTION:An apparatus for measuring the closest distance of a moving object under water is provided with a receiving means 10 for receiving sound waves, a first ordr differentiation waveform measuring means 11 and a second ordr differentiation waveform measuring means 12 to output a first ordr differentiation value and a second order differentiation value of a received sound pressure by an output of the receiving means 10 respectively and a distance computing means 13 which obtains inversion information in respective polarity of the first and second order differentiation values by outputs of both the measuring means to compute the closest distance. It is possible not only to detect the passage of the moving object at the closest point and but also to measure an absolute value of the closest distance easily. This also enables the measurement of the closest distance by a handy system using a single sensor alone thereby achieving effective starting of a finite number of entry prevention means such as entry prevention system and further enables the optimum measuring system for realization as entry prevention means serving as consuming type small sensor concurrently in a price due to the handiness of the system.

Title: Low constant pressure device
Inventor: MIYAZAKI TAKESHI
IPC: G01B21/02
Filed: 1984-07-16
Abstract: PURPOSE:To prevent deforming force from being applied to a body to be measured by providing a spring pressure adjusting means for a coil spring and setting optional measurement pressure. CONSTITUTION:If measurement force larger than the energizing force of the coil spring 45 is applied after the tip end surface of a driving spindle abuts on the body to be measured, a spindle 20 is displaced backward in the opposite direction of the driving spindle 82 against the energizing force of the coil spring 45. In this case, a differential transformer 60 provided to one terminal side of the spindle 20 detects the displacement of the spindle 20 and the displacement is displayed on the scale with the pointer of the display part of a display device, thus obtaining the size of the objective body. In this case, a simple 68 is rotated and adjusted to vary the length of a coil spring 45 and adjust the measurement pressure applied to the objective body with the tip surface of the spindle 20, thereby taking a measurement with the optimum measurement pressure.

Title: Semiconductor capacitor
Inventor: DENDA MASAHIKO
IPC: H01L27/10
Filed: 1979-11-14
Abstract: PURPOSE:To obtain a dynamic memory preventing software error occurred due to alpha rays by using a polycrystalline semiconductor film formed through an insulating film on a semiconductor substrate as an electrode layer of an MOS capacitor. CONSTITUTION:An oxide film 8 is selectively formed on the surface of a p type substrate 6, is coated with a polycrystlline silicon film 7, and the film 7 is patterned. Then, it is oxidized with oxidation resistant mask, and an isolating silicon oxide film 9 is formed thereon. Thereafter, gate oxide film 1, polysilicon films 2, 3, gate oxide film 4 and n<+> type region 5 are formed by an ordinary dynamic memory forming process. Since the memory capacitor is thus surrounded by the oxide film if electron and hole pair are formed due to the irradiation of the alpha rays, it is not affected by the interruption of the oxide film, thereby preventing the occurrence of the software error.

Filed: 1994-06-30
Abstract: PURPOSE:To obtain a line of sight detector which enables accurate detection of the line of sight simply by arranging a memory means to store a correction value set previously to correct a deviation between the line of sight and an optic axis and a control means to control the detection of the line of sight based on the correction value. CONSTITUTION:An infrared light source 13 is arranged to be a spot light source and when the position of the light source 13 is adjusted to emit light at the position in the center of a screen on a focusing plate 7. Purkinje's images appear as spot images in a straight line on the optical axis of an eye ball. On the other hand, when with the turning of the eye ball, an optic axis shifts in one direction biased to the left or right, illumination light enters askew to the optical axis of the eye ball and the Purkinje's images move to a position eccentric from the pupil. Hence, a plurality of the Purkinje's images are recognized as viewed from the front. To correct the deviation between the direction of the light of sight and the direction of a gazing point, one method is the deviation is measured separately to input a correction value according to the results. Generally speaking an average correction value of human eyes is stored into a microcomputer mc to control the detection of the line of sight based on the correction value.

Title: Angular velocity sensor
Inventor: YOSHIDA MASANORI
IPC: G01C19/56
Filed: 1991-06-21
Abstract: PURPOSE:To make the change in sensitivity in a detecting part small and to enhance detecting accuracy by specifying the value of a mechanical quality coefficient in the direction of the thickness of the detecting part of an angular velocity sensor so that the ratio between the natural frequency of the detecting part in the direction of the thickness and the natural frequency of a driving part in the direction of the thickness satisfies the specified relationship. CONSTITUTION:In an angular velocity sensor, a driving part is vibrated and driven by the application of an AC driving voltage. The bending state of a detecting part in the direction which is orthogonal to the vibrating direction is electrically detected, and the angular velocity is detected. At this time, a mechanical quality coefficient QS of the detecting part in the direction of the thickness is 50 or more and 500 or less. The ratio fS/fD between a natural frequency of a detecting part fS in the direction of the thickness and a natural frequency of a driving part f is set so as to satisfy the expression of 1.2-0.0002XQS<=fA/ fD<=1.52-0.0005XQS. Thus, the natural frequency fD is set in a flat region wherein the resonance characteristic of the detecting part in the direction of the thickness is flat, i.e., the region wherein the change in sensitivity of the detecting part is small. Therefore, even if the driving frequency of the angular velocity sensor is changed, the change in sensitivity of the detecting part can be made small. Thus, the angular velocity sensor having the high detecting accuracy can be obtained, and the dispersion among the sensors can be decreased.
