  • Publication number: 20090298219
    Abstract: A method for manufacturing a solid-state pickup device module of the present invention includes: a step of processing a transparent substrate so that each of transparent substrates for a chip is held opposite to each of solid-state image pickup devices when the transparent substrate and a substrate having a plurality of solid-state image pickup devices are opposed to each other (step of processing a transparent substrate; S1 to S17); and a modularizing step in which the transparent substrate thus processed and the substrate having a plurality of solid-state image pickup devices are opposed to each other so as to place each of the transparent substrates for a chip opposite to each of the solid-state image pickup devices (modularizing step; S21 to S28). Thus, the present invention can improve manufacturing efficiency by bonding the transparent substrate and the substrate having a plurality of solid-state image pickup devices at a time.

  • Patent number: 7605057
    Abstract: A method of manufacturing a semiconductor device can suppress the generation of burrs when an array of integrated circuits to which a supporting member is bonded for assistance is separated into chips. The supporting member having thinned regions (or void regions which are openings in the supporting member) located correspondingly beneath the scribing lines extending between the integrated circuits is bonded by an adhesive to the back side of a semiconductor substrate on which integrated circuits are arrayed at the primary side. Then, a dicing tape is attached to the support member to secure the entire assembly, and the assembly of the integrated circuits, the semiconductor substrate, the adhesive, and the supporting member are cut along the scribing lines, and then the dicing tape is removed.

  • Patent number: 6868362
    Abstract: There is disclosed a power-saving sensor system such as a distance measurement sensor making use of light projection type triangulation. The sensor system has a sensor means and a CPU for controlling the supply of electrical power to the sensor means, accepting the output from the sensor means, and performing desired processing. The CPU turns on signals P1, P2, P3 in response to a trigger signal Tp from a timer circuit, thus supplying electrical power to a distance measurement module. A distance measurement IC within the module produces an emission signal when the operating signal P3 is turned on. This activates the sensor means to perform a measurement of a distance. The presence or absence of an object is determined from the detected distance value. According to the presence or absence, a transistor Tr2 is turned on or off. A signal indicating the distance or the presence or absence of an object is produced from a terminal T8.

  • Publication number: 20040206622
    Abstract: A plating processing device is so arranged that at least a part of a portion touching plating liquid is made of a material whose change rate of surface roughness in response to a removing agent is lower than resin when the material and the resin are measured in the same conditions. For example, a storage tank (1), a plating processing tank (2), a buffer tank (3), and a pipe (9) are made of hard glass and quartz glass. With this, it is possible to prevent a plating material from being deposited as foreign body on wall surfaces of the plating processing tank, etc.

  • Patent number: 6650833
    Abstract: To prevent temporary reduction of battery voltage when driving a shutter, an exposure control drive apparatus is provided with a boosting circuit for boosting a voltage of the battery and outputting a boosted voltage. A capacitor is charged by the boosted voltage for driving an actuator of an exposure control mechanism. A detecting circuit detects a current flowing in the boosting circuit and a control circuit controls operation of the boosting circuit in accordance with a magnitude of the detected value so that the boosting circuit is prevented from boosting the battery voltage when the detected current exceeds a predetermined level and is permitted to boost the battery voltage when the detected current is below the predetermined level. In this manner, the current flowing from the battery is prevented from exceeding a maximum level.

  • Patent number: 6509963
    Abstract: It is possible to enhance accuracy in photometry measurements without an increase in unnecessary actual measurement data and design value data in the case where on a low ambient luminance side, an output of a first light sensor, which receives light collected from a large area, is linear and an output of a second light sensor, which receives light collected from a small area, is non-linear. The number of luminance measurement points used for performing measurement with the second light sensor is set at low ambient luminance values to be larger than the number of luminance measurement points used for performing measurements with the first light sensor.

  • Patent number: 6100983
    Abstract: An object sensing apparatus comprises a distance measuring device for measuring a distance to an object to be sensed, and a filter member having a surface disposed in confronting and spaced-apart relation to the distance measuring device. The distance measuring device has a light projecting element for projecting light toward the object and a light receiving element for receiving the light projected by the light projecting element and reflected by the object. The filter member is disposed at a preselected angle of inclination with respect to the distance measuring device. When the light projecting element projects light toward the object, light reflected or scattered by the surface of the filter member is directed in a direction away from the light receiving element.

  • Patent number: 6058270
    Abstract: A low cost, low power photometric circuit suitable for use in a low end camera includes a first counter for counting successive pulses produced by a first oscillator having a substantially constant oscillation frequency and a second counter for counting successive pulses produced by a second oscillator having an oscillation frequency which varies in accordance with ambient brightness. The ambient brightness is judged according to outputs of the counters so that even if the oscillation frequency of the second oscillator varies only slightly due to a change in ambient brightness, the slight variation is easily detectable as an accumulated count value. Accordingly, costly, high-precision components are not needed. The low cost photometric circuit requires no microcomputer, analog/digital converter or comparator and can be fabricated in a single integrated circuit operated at a low voltage of 1V or less, and is thus suitable for incorporation into a low end camera.
