    摘要: If after manufacture it is found that the thickness of a solid immersion lens is less than a target thickness value, an adjustment portion is adhered thereto by vapor deposition so as to reduce the amount of thickness deficiency. If the solid immersion lens is made of quartz glass, SiO2 is used as the material which is vapor deposited. If the thickness of the solid immersion lens is greater than the target value, then it is reduced by etching.

    摘要: A pyroelectric infrared array sensor has a pyroelectric element on which a plurality of sensing sections are formed, each of which has upper and lower electrodes which confront each other through the pyroelectric element. To fixedly secure the pyroelectric element to a substrate, lead conductors extended from sensing sections located adjacent to the edges of the light receiving surface of the pyroelectric element are fixedly connected to the substrate by conductive paste. The lower electrodes are connected to solder bumps on the substrate with conductive paste. The respective dimensions of the solder bumps can be adjusted so as to adjust the amount of heat conducted away from the sensing sections and thereby make the heat-sensitivity of the sensing sections more uniform. Alternatively or in addition, the amount of conductive paste used to connect the lower electrodes to the solder bumps can be adjusted for the same purpose.

    摘要: A random access system for recording and/or reproducing apparatus of the type used for recording information on and/or reproducing information from addressable portions of a record medium. The random access system is capable of recording address signals on the medium adjacent corresponding addressable portions and of playing back address signals from the medium so as to access any addressable portion thereof to reproduce information therefrom. The address signals are constituted by a variable number of address pulses plus a constant number of pulses. The random access system includes a counter for counting pulses which are applied thereto so as to derive a count corresponding to an address. A detector detects the constant number of pulses included in an address signal and supplies only the variable number of address pulses to the counter. A selector is operable to select any one of predetermined addresses, and a comparator compares the count derived by the counter to the address selected by the selector to produce a coincidence signal when the count is equal to the selected address. In a recording mode, an oscillator generates a substantially continuous train of pulse signals which are supplied through the detector to the counter. A record control circuit is operable to initiate an address recording operation for transmitting the train of pulses to the counter, and is responsive to the coincidence signal to terminate this address recording operation. In a playback mode, the recorded address signals are supplied through the detector to the counter. A sensing circuit is provided to sense the end of the played back address signal and to actuate a control signal generator which is responsive to the coincidence signal for generating a control signal which is adapted to initiate a predetermined operation of the recording and/or reproducing apparatus.
