A shield connector assembly comprises an electrically insulative connector body, and an electrically conductive shielding shell fitted onto the electrically insulative connector body. The shield connector assembly further comprises two electrically conductive lock blocks having engagement elements which are to be subjected to connection with mating connectors. The lock blocks are individually attached to opposite ends of the connector body onto which the electrically conductive shielding shell is fitted, thereby surely contacting the electrically conductive lock blocks to the electrically conductive shielding shell.

The present invention provides a resin tablet for plastic encapsulation molding by the transfer molding process. A tablet body is obtained by compressing powdered thermosetting resin and is covered by a covering membrane. A method of manufacturing a plastic encapsulation using such a resin tablet includes exposing the surface of tablet body by breaking the covering membrane in a pot and pressing the thermosetting resin of exposed tablet body with the plunger for encapsulated molding.

In a sandwich type image sensor having a photoelectric converting portion comprising a photoelectric conductive layer interposed between an upper electrode and a lower electrode, a light-shielding means is provided for selectively covering an end portion of the photoelectric conductive layer so as to be excluded from a light-receiving area of the converting portion. Alternatively, an insulating layer partly blocking the contact between the photoelectric conductive layer and the lower electrode is provided for effectively defining the light-receiving area of the converting portion. In an example where the photoelectric is divided so that it is operable as those of a plurality of sensor elements arranged in a row, a light-shielding means is provided for defining light-receiving areas of the sensor elements, while overlapping areas of the upper and lower electrodes are adjusted for equalizing the stray capacitances of the sensor elements inclusive of their connecting portions.

In an ionization chamber detector of the type in which a plurality of flat anode and cathode electrodes are alternately arranged in a predetermined gaseous medium, this invention provides a method of producing an ionization chamber detector which is characterized in that a plurality of ditches having a width a little bit greater than the thickness of the electrodes are formed on the inner surfaces of a pair of insulators disposed in the spaced-apart relation for supporting and fixing the anode and cathode electrodes, an adhesive is applied in advance temporarily in a rectangular form to both or one surface of each electrode at those positions which are set back by a distance corresponding to the thickness of the electrodes from both edge portions, another adhesive having a low viscosity is charged from the end portions of the ditches into the gaps between the electrodes and the ditch walls after the electrodes are inserted into the ditches, and the tentative adhesive and the adhesive having a low viscosity are then cured integrally in order to firmly bond and fix the electrodes into the ditches. This method can keep the distance between the electrodes highly accurate and can bond and fix reliably and stably the electrodes into the ditches.

Methods and systems for azimuth measurements using a gyroscope unit are disclosed. The method includes acquiring a ratio value between two earth rate components orthogonal to each other by using the gyroscope unit at a measuring position; acquiring three gravity vector components orthogonal to each other at the measuring position; and determining an azimuth with respect to a reference axis predetermined in the gyroscope unit, based on the ratio value, the three gravity vector components and a geodetic latitude of the measuring position.
