Title: Vehicle sensing device
Inventor: KURODA ETSUJI
IPC: G01S13/56
Filed: 1990-04-13
Abstract: PURPOSE:To reduce a measurement error due to a shift in speed measurement position by providing a processing part which uses the output of a reflection intensity amplifier as a vehicle presence signal and also as vehicle speed measurement start timing. CONSTITUTION:The processing part 16 starts measuring the speed at the rise of the presence signal outputted by a comparing circuit 12 to calculate the mean period of the output signal of a Schmitt circuit 9. At this time, the Schmitt circuit is allowed to send the output signal only when the presence signal is significant and then an accurate Doppler mean period T is obtained. The speed (lambda/2T)costheta is small in variation of theta, so the measurement error is reducible. A suspension time a/v+b is added to the vehicle presence signal according to the accurate measured speed (v) to make the presence signal more accurate.

Title: Ion beam device
Inventor: TAMURA HIFUMI
IPC: H01J37/02
Filed: 1984-05-18
Abstract: PURPOSE:To subject the sample to micro-processing or analyze a very small area of the sample using a thin flux ion beam discharged from a liquid metal ion source by maintaining the temperature of the sample surface higher than the melting point of an ionic substance. CONSTITUTION:While the temperature of a sample 3 is maintained higher than the melting point of a primary ionic substance by means of a heater 5 or 10, the sample 3 is subjected to processing or analysis by irradiating an ideally placed beam 2 upon the sample 3. Irradiation efficiency and analytic sensitivity can be improved by introducing an active gas as necessary so as to prevent any adhesion of a primary ionic substance to the sample surface, thereby improving the accuracy of the irradiation and the analysis. Heating of the sample 3 and introduction of the inactive gas greatly improves irradiation speed and analytic sensitivity.

Abstract: PROBLEM TO BE SOLVED: To set an electron emission distribution to an axial symmetry by quarrying a material, so that an orientation of a crystal axis of a crystal bar of the material coincide with an axis of an electron emitting unit in a lengthwise direction. SOLUTION: A plane of a disc-like cutter of a machining apparatus is brought into contact with a cleaved surface 20, a cut surface of the cutter is set parallel to the surface 20, and a chip base material 2 is quarried so that the cut surface of the material 2 become parallel to the surface 20. Then, since the surface 20 is perpendicular to a crystal orientation, the material is quarried so that an axial direction of the chip 3 coincides with the crystal orientation. And, the chip 3 is processed so that the axial direction 5 of the chip 3 coincides with the axial direction of an electron emitting unit to manufacture the emitting unit.  The unit is disposed so that the axial direction of the unit coincides with a direction of an axis for passing an electron beam of an electron beam apparatus, and the apparatus is mounted at an electron beam source, and a voltage is applied to generate an electron beam. Thus, emitted electrons are at an axial symmetry to the axial direction. An electron emitting distribution becomes an axial symmetry, and hence electron can be uniformly emitted to a sample.

Filed: 1990-04-13
Abstract: PURPOSE:To suppress a change in an image density attended with the change in humidity with inexpensive constitution by providing a control member causing a volume change according to the humidity, and driving a regulating plate. CONSTITUTION:A developer housed in a case 2 sticks the outer periphery of a developing sleeve 22, and a photosensitive drum 8 is developed with the stuck developer. The height of the sticking of the developer to the developing sleeve 22 is regulated by the regulating plate 26 to be made to a proper value.

Filed: 1983-06-03
Abstract: PURPOSE:To facilitate assembly and adjustment, and reduce the number of parts and attain size reduction by constituting a semiconductor laser and a photodetecting element which detects a reflected light output in one direction of the semiconductor laser in one body. CONSTITUTION:A photodetection part 14 incorporates integrally the photodetecting element 9 which detects reflected light in one direction of the laser 4.

Title: Data memory hierarchical system
Inventor: KONII MEI KURAAKU
IPC: G11B27/32
Filed: 1989-04-20
Abstract: PURPOSE: To simplify the destaging technique by using an optical disk library and a manual operation shelf storage which is used for the individual optical media. CONSTITUTION: When it is required to store the specific data into an optical disk library 20, a host processor 50 checks whether an optical disk contained in the library 20 presently has the capacity enough to store the specific data. If the optical disk has no necessary capacity, the optical disk that is most precedently loaded into an optical disk drive 40 in the library 20 is destaged to a manual operation shelf storage 30 from the library 20 regardless of an access of the processor 50 given to the disk. Then another disk is supplied to the library 20 to store the data. Thus the destaging technique is simplified.

Filed: 1993-04-26
Abstract: PURPOSE:To enable the display of video where blurring is deleted by displaying the video at a location which is shifted in the direction cancelling a displacement when the analysis result of the video or the angle speed detected and recorded at the time of a photographing exceeds a fixed value. CONSTITUTION:As the processing of each frame, the video stored in a video storage part 21 from a tape 22 is read at first and the flow of video is analyzed from the neighboring frame image.
