Title: 2-d velocity detector
Inventor: TACHIKAWA HAJIME
IPC: G01P3/36
Filed: 1985-10-02
Abstract: PURPOSE:To measure linear and angular velocity in a non-contact manner, by a method wherein after the irradiation of energy to a material, the feature point obtained from energy distribution of an object is determined and then, a relative linear velocity and angular velocity are discriminated from the hourly transition of the feature point. CONSTITUTION:A robot 1 runs to the left on a road surface 2 at a linear speed V with wheels 3 and 4. An infrared laser generator section 5 as energy radiating section and 2-D stationary camera 6 as residual image detecting section are set on the bottom of the robot 1. When a speed measurement start signal is given to a speed decision circuit 7 from a main controller of the robot 1, a power is supplied to the laser generating section 5 from a laser power source 8 to spot in a pulse to a part 2' at the center of the view of a camera 6 provided on the road surface 2. The camera 6 receives a temperature distribution immediately after the irradiation of the laser and feeds a pattern thereof to the circuit 7. The circuit 7 extracts the feature point to determine transition coordinates from the hourly transition of the feature point thereby enabling the measurement of linear velocity and angular velocity in a desired direction.

Title: Producton of core for coaxial dielectric resonator
Inventor: HOSOYA TAKESHI
IPC: C04B35/64
Filed: 1991-08-29
Abstract: PURPOSE:To obtain a dielectric core with high measurement accuracy while equalizing the filling of a material without generating deformation and warping by obtaining the material while heating and kneading the specific amount of a binder with the dielectric powder and extruding the material in a mold. CONSTITUTION:A slurry material is obtained by heating and kneading the binder with 15 to 50vol.% with the dielectric powder. The material is extruded into the inside of the mold to form a dielectric core raw material with complicated shape. The raw material is slowly heated up until 100 to 500 deg.C at the rising temperature rate, degreasing the binder. Then, the dielectric core after degreasing is held for the prescribed time at the high temperatures of 1000 to 1400 deg.C to be sintered and the dielectric core is obtained. Therefore, since it is formed by extruding the slurry fluid raw material excellent in fluidity, the filling of the material in the mold is equalized. Thus, a core with high measurement accuracy is obtained without generating warping and deformation, etc., after the sintering.

Abstract: PROBLEM TO BE SOLVED: To enhance resistance to environment change such as temp. change and dust, to easily and freely attach/detach a circuit board and also to improve the transmission efficiency of signal light by collecting outgoing signal light towards a signal receiving parts arranged along an outgoing end surface. SOLUTION: A sheet-shaped optical data bus 10 is provided with an optical transmission layer 11 and a clad layer 12 which is formed so as to sandwich the optical transmission layer 11. One end surface of the optical transmission layer 11 is a signal light incident end surface 13 on which a signal is made incident, and the other end surface positioned at the opposite side of one end surface is a signal light outgoing end surface 14 from which signal light is outgone and the signal light outgoing end surface 14 is formed into a projecting surface shape. Therefore, signal light projected from the signal light outgoing end surface 14 is collected at a position a little apart from the signal light outgoing end surface 14 so that the position is adopted as a signal light receiving part for arranging a photodetector, for example.  Thus, signal light is efficiently transmitted to the signal light receiving part and made to be tolerant of environment change without generating electromagnetic noise.

Title: Driving method for end face light emission type el element
Inventor: TAMURA TOSHIYUKI
IPC: H05B44/00
Filed: 1990-08-20
Abstract: PURPOSE:To reduce deterioration without reducing an emitting light intensity by setting special relationship among a time from application of a driving pulse to an EL element to arrival of the intensity of the emitting light at a peak, a time from the peak to '0', and a time from start of application of one driving pulse to start of next application. CONSTITUTION:When a time from application of one driving pulse to an end face light emission type EL element to arrival of the intensity of an emitting light at a peak is Tta, a time from peak of the intensity of the light to the element to '0' is Tts, and a time from start of application of one driving pulse to the element to start of next application of the pulse is Ths, relationship of Tts>=Ths>=Tta is satisfied. Thus, since the application of the pulse is started while the after light of the previous light emitting exists, the intensity of the emitting light of the element can be improved. Further, the rise of the frequency of the pulse more than required is prevented to satisfactorily improve the intensity of the light.

The seam welding is achieved so that the ratio of the circumferential speed S of the rotation type rolling reduction roll to the traveling speed R of the frame satisfy the inequalities: S/R>=1.1 when 0.4mm<=(t1 +t2 )<=2.0 mm, and 0.9<=S/R<1.1 when 2.0mm<(t1 +t2 ), where t1 +t2 is the total value of the thickness of the preceding and succeeding steel sheets.  Tear of the weld zone by the rolling reduction roll can be prevented.

Abstract: PURPOSE:To contrive to improve the performance in short channels by eliminating abnormal phenomena such as the increase in output conductance and the variation in gate threshold voltage by a method wherein the depth of an N<+> contact layer measured from the surface of an electron layer and the distance between contact layers are made specific. CONSTITUTION:The thickness of N<+> contact layers 13 and 14 measured from the surface of a channel layer is de, and the distance between the contact layers is Le. At this time, the substrate current 20 has the average electric field between the contact layers far exceeding a threshold electric field of speed saturation of electrons in a saturated region of FET of short channel length. In this case, setting de under the condition shown by Formula enables the negligence of effects of the substrate current. This can yield a good characteristic of saturation with a very small drain conductance of FET dynamic characteristic. Besides, there is little increase in resistance due to the reduction in de.
