Title: Equipment with parts to be pressure-connected
Inventor: GUREGU II BURONDAA
IPC: G02B6/42
Filed: 1994-01-11
Abstract: PURPOSE: To easily manufacture an airtight housing by providing a texture bonding region, in which one of first and second members has a ridge within the bonding region and the ridge substantially surrounds a non-contact internal region. CONSTITUTION: A recess 13 is provided at a surface 12 of a box 10, to form the inside of the box 10. A laser 15 is mounted on a sub-mount 14 in the recess 13 for providing electrical contact means 16, 17.

Title: Semiconductor photo detector
Inventor: YAMAGOSHI SHIGENOBU
IPC: H01L31/0264
Filed: 1989-01-20
Abstract: PURPOSE:To obtain a highly efficient detector in a very long wavelength band capable of easy incidence into a quantum well layer by securing sensitivity regardless of electric field direction of incident light, when the light is made to enter parallel with a substrate. CONSTITUTION:A quantum well layer 2 is formed on two inclined surfaces which are formed on a substrate 1 and intersect with each other. Since the directions of electron dipoles on the inclined surfaces A and B are different with each other the incident light can be absorbed on the inclined surface A or B, whichever direction the electric field of the light faces to. When the transition of electron in the quatum well between quantized levels is considered, the direction of electron dipole becomes vertical to the quantum well layer. When the light enters vertically to the quantum well layer, light absorption is not caused, because the electric field vector makes right angles with the incidence direction. In order to couple the light with the dipole in the case of vertical incidence, the electron well layer is necessary to be inclined to the crystal surface. That is, substrate crystal is processed and turned into an inclined surface, on which a quantum layer may be grown.

Title: Method and device for measuring stereo image
Inventor: ONDA KATSUMASA
IPC: G06T7/00
Filed: 1994-02-04
Abstract: PURPOSE:To enable correlation of two screens having no established epipolar condition obtained with actual stereo camera arrangement by using a relative three-dimensional rotation angle. CONSTITUTION:At least two linear lines parallel to each other in the real space are extracted from each image data obtained individually with two cameras and a relative three dimensional rotation angle between the two cameras is estimated. By using the obtained relative three dimensional rotation angle, the images obtained with the two cameras are corrected with parallel movement transformation, rotational transformation and the like, and the two images are correlated. When the relative three dimensional rotation angle became larger than a preset threshold value, it judges there are possibilities of unavailability of stereo image measurement or loss of accuracy in the measured data and gives alarm.

Title: Display memory controlling circuit
Inventor: GOMIKAWA TAKAO
IPC: H04N7/08
Filed: 1984-01-26
Abstract: PURPOSE:To prevent the operation of a display memory from faulting by detecting timing just before presetting X address data by a counter and prohibiting a pulse from accessing to the display memory. CONSTITUTION:The output of a timing counter 12 is inputted to a decoder 401 and decodes the access period of the display memory 11, and at the same time, supplies access gate pulse to a shift register 402. The shift register 402 shifts the access gate pulse to the unit of display dot, and generates a gate pulse string in various phases. The gate pulse is used as access pulse of the display memory 11 through gate circuits 403, 404. A counter 405 is cleared by a horizontal direction indication preset pulse from a terminal 18, and feed a prohibition pulse at timing immediately before to prevent the output of access pulse from the gate pulse 404 to the display memory 11 in the period unnecessary for display.

Abstract: PURPOSE:To enlarge a main lens diameter under limitation of a neck diameter and to improve focusing characteristics by forming without axial symmetry, each opening between two pairs of electrodes provided with plural number of openings formed in the lateral direction and by providing auxiliary electrodes in very vicinity of the openings. CONSTITUTION:Respective electron beam passing holes 4'', 5'', 6'', and 7'' of the third grid 4, the fourth grid 5, the fifth grid 6 and the sixth grid 7 are formed with simple circular openings provided by a press punching processing. As an electric potential distribution corresponding to each opening does not keep symmetry with respect to the central axis, auxiliary electrodes 4c-7c for compensation of electric potential ditribution are fixed and disposed individually between electron beam passing holes 4''-7'' adjacent to each other so as to make compensation. The size w of the electric field auxiliary electrodes 6c, 7c and the interval g therebetween are selected properly to make the shape of the beam almost circular and an astigmatism is negated. A substantial electrode opening diameter is larger than the practically provided opening, and diameter enlargement can be realized.

If the image-forming position of the incident parallel light beam from afar which has passed through the plate 4 is set to a point 14, the image-forming positions of the light beams which have passed through the parts 6, 6 and 7 are set to points 15, 16 and 17. If the distance between the image-forming positions is set to half the array period of the elements 2, and the size of the elements 2 to more than a half of the period, one point among four positions on the element 2 without fail. Thus, a blind sector with respect to the remote light source can be eliminated with a simple means.

Abstract: PURPOSE:To obtain an ohmic contact having stable characteristics in a method of forming an electrode on the back surface of an opitaxial type semiconductor device by mixing by a powder metallurgical method electrode forming metal and N type impurity metal and employing the product as deposited source. CONSTITUTION:Heat is applied to ultrafine particles of Cr 20 and Sb 21 to an Si substrate 1, which is then pressed, thereby producing a small lump of Cr-Sb mixture 19, which is used as a deposited source. When an electron beam 18 is emitted at a high speed to the source 19, the Cr 20 and the Sb 21 are molten and are scattered. Thus, the Cr and the Sb are deposited on the back surface of the substrate 1, thereby forming a CrSb layer 22. An Ni layer 23, an Sn layer 24 and a silver layer 25 are sequentially formed on the layer 22. When the substrate 1 is heated at this time, the Sb of the layer 22 is diffused in the substrate 1, and the desired N<++> type impurity region is formed on the back surface of the substrate 1, and an ohmic contact can be sufficiently obtained.

The circuit 311 reports fault contents to a diagnostic device 301 by this request, and the device 301 analyzes fault contents; and if the device 301 discriminates that the error of a control storage 313 should be corrected, the device 301 transmits correction information to the circuit 311 and indicates the write of corrected control information to the storage 313 at the error detection time. Each time an correctable error is reported, the circuit 311 writes corrected control information to the control storage 313.
