Title: Printed matter inspecting device
Inventor: NISHIDA MASASHI
IPC: G01N21/89
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To conduct stable defect inspection by measuring the number of picture elements exceeding a predetermined level difference within a predetermined rectangular area of a defect determination processing unit of defect candidate image and determining a defect when the number of picture elements exceeds a predetermined number of picture elements. SOLUTION: A picture pattern of a printed matter 4 is made to be an image data by a camera 11 of an input section 10, converted into digital form, and inputted to a processing section 30 through an optical fiber 8. The section 30 obtains a monochrome data from a color data obtained by shading correction of the input, it is stored in a reference image or inspection image memory, and an absolute value of difference is calculated at each picture element in consideration of quantity of misregistration. Corresponding images of a difference image memory and a threshold image memory of this value are compared. Only a difference value which exceeds a threshold value is stored in a defect correction image memory.  From combination of the reference image, a level difference of each picture element of a defect image, and the number of picture elements exceeding the value of the picture element, a type of a defect is discriminated. The defect is displayed on a monitor 41 by an operation section 40 and an alarm is issued. Accordingly, defective parts in one screen can be determined individually and stable inspection can be done without complicated processing.

IPC: H04W88/00
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To make a repeater take one part of a push type information distribution service in place of an information provider(IP) server. SOLUTION: The user of mobile equipment MS prepared for receiving an information provision service from an unspecified IP accesses a gateway server GWS and performs a registration procedure in advance (S71). When the desired information to be provided for the user is generated, on the other hand, an IP server W constitutes this information as electronic mail and transmits it to the gateway server GWS while adding the attribute data of the user to the electronic mail (S72). When the electronic mail, to which the attribute data are added, is received, the gateway server GWS stores the electronic mail in a third mail box BOX3, performs the matching of a user attribute and calls the mobile equipment MS of the relevant user (S73). The called user requests the download of electronic mail to the gateway server GWS (S74).  The gateway server GWS transmits the electronic mail to the mobile equipment MS that requests the mail (S75 and S76).

Title: Method for compensating load weight of manipulator
Inventor: YABUTA TETSUO
IPC: G05D3/12
Filed: 1986-10-15
Abstract: PURPOSE:To obtain the compensation command voltage with use of a correction function obtained from a yacobi matrix by applying control of integration (I) to a manipulator and therefore decreasing satisfactorily the deviation from the target position of the manipulator. CONSTITUTION:The increment of servo command voltage is measured when the load weight is applied in a state where the control function of integration (I) is used at a reference measuring point to set the deviation of the target value at about zero. Based on this measurement result, the feed-forward control for compensation of the load weight is carried out at a general position of a manipulator in place of the control function of integration (I). Thus, it is possible decrease the target value deviation approximately like in the case of the control of integration (I). Furthermore, the responsibility can be greatly improved compared with the control of integration (I).

Title: Manufacture of semiconductor element
Inventor: KUNIHIRO TAKASHI
IPC: H01L21/02
Filed: 1992-09-14
Abstract: PURPOSE:To obtain a second epitaxial growth layer which has an improved flatness by using selective epitaxial growth, instead of isotropic etching, for silicon and thereby eliminating troubles specific to isotropic etching. CONSTITUTION:A p-type epitaxial layer 12 of mesa shape is formed on a semiconductor substrate 1 by a selective epitaxial growth method. A mask layer 13 is formed on the uppermost layer of the mesa epitaxial layer 12. A silicon film containing Sb is deposited on exposed parts of the semiconductor substrate 1 and the mesa p-type epitaxial layer 12. The collector 15 of a transistor is formed by heat treatment, and then an n-type epitaxial layer 16 is formed. The resultant device is then subjected to a 'mecha-chemical' polishing process involving chemicals, which is so designed that the polishing operation is automatically stopped when the mask layer 13 is reached. This obtains a semiconductor element which enables higher degrees of integration, making it possible to manufacture integrated circuits having a high breakdown voltage.

Title: Split sleeve for optical connector
Inventor: MATSUSHITA NOBUHIKO
IPC: G02B6/36
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To stabilize a connection loss value and the repetitive detachability of the ferrule of a split sleeve by providing a cylindrical inner peripheral surface with a specific number of protrusions arriving at the other end from one end in the longitudinal direction and forming the top surfaces of the protrusions to an arcuate shape. SOLUTION: The split sleeve 1 is formed to a shape provided with a slit 15 at the cylindrical body and the inner peripheral surface 12 is provided with the protrusions 11 arriving at the other end from the one end in the longitudinal direction at seven points. The top surface 14 of the protrusions 11 are formed to the arcuate shape formed by precision polishing to a diameter slightly smaller than the outside diameter of the ferrule around the central axis 13 of the cylindrical body. The top surfaces 14 of the protrusions 11 at the seven points may be processed to the out of roundness higher in accuracy than an ordinary split sleeve free from the protrusions and more particularly the sleeve may be adequately used for connection of the ferrule of an angle PC shape.  If the number of the protrusions 11 is below 7 points, the flaring of the split sleeve 1 is large and the angle PC connection loss is degraded. If the number is above 11 points, the chipping of the sleeve is resulted at the formation of the slit 15 and the embodiment of this split sleeve is impossible. Then, the number of the protrusions 11 is specified to >=7 to <=11 points.

Abstract: PROBLEM TO BE SOLVED: To obtain appropriate adjustment state after the mode changeover by resetting a focus adjustment means corresponding to the changeover of the function mode and keeping a photographing magnification at a final point of time of the photographing mode in a power supply state. SOLUTION: A control section 8 selects the function mode by a mode changeover command from a photographing/reproduction changeover switch 15 and focus control systems 11, 13 and zoom control systems 12, 14 conduct control of the normal operation for a period of the photographing mode. In the case of selecting the standby mode or the reproduction mode, the control section 8 once resets only the focus control systems 11, 13 and inactivates them and inactivates the zoom control systems 12, 14 while keeping the state at a final point of time of the photographing mode in the power supply set state without resetting the systems 12, 14. In the case of selecting the photographing mode from the standby mode or the reproduction mode, the focus and zoom control systems are restored to the normal operation state from the inactivated state.  Thus, immediate changeover is attained in the case of restoring the state to the photographing mode.
