Only a front end part 16 of a surgical microscope 15 is turned in a left-right direction X around a main axis S, so that an observation angle of a surgical site T is freely changed in the left-right direction. Even if the observation angle is changed, the orientation of eyepieces 22 is unchanged, and therefore, an operator does not need to bend his or her neck and no burden is imposed on the neck of the operator even if the operator must conduct an operation that takes a long time.

A slit 9 having a predetermined length is formed in a mirror 8 and an illumination light L of illumination part 10 irradiates an observation area E in a manner of zero-angle illumination to an optical axis K. The illumination part is movable to form an oblique path of the illumination light L which passes through the slit 9. A shadow appears due to the oblique path of the illumination light L and it facilitates a stereoscopic observation.

An image processing device with a configuration enabling generating of images from a new viewpoint by simple signal processing is provided. Input image signals for the right eye, and input image signals for the left eye to be applied to image display are input, and a right image converting unit generates a converted image where the input image signals for the right eye have been subjected to phase change in the right direction or the left direction, in accordance with features of the image. In the same way, a left image converting unit generates a converted image where the input image signals for the left eye have been subjected to phase change in the left direction or the right direction, in accordance with features of the image. The generated image of the right image converting unit and the generated image of the left image converting unit are output as multiple new viewpoint images. A converted image is generated by processing where a luminance differential signal of an input image, or a nonlinear conversion signal of the luminance differential signal is added or subtracted, to or from the input image signal, for example.

A placing member (80) is configured to be supported from an outside by a terminal (81) electrically connected to a terminal electrode, and an X-axis-direction extended portion (84), a Y-axis-direction extended portion (82), and a Z-axis-direction extended portion (83) are provided in the terminal (81). This configuration provides an angular velocity sensor, in which a problem such that Y-axis-direction and Z-axis-direction vibrations applied from the outside cannot be damped is eliminated, and all the vibrations in three axis directions can be damped.

A triorganosiloxy end-capped organopolysiloxane, i.e., organopolysiloxane having a backbone consisting essentially of repeating (3,3,3-trifluoropropyl)methylsiloxane units and end-capped with triorganosiloxy groups is prepared by copolymerizing tris(3,3,3-trifluoropropyl)trimethylcyclo-trisiloxane with a silanol end-capped organopolysiloxane in the presence of an alkyllithium or lithium silanolate catalyst to form a silanol end-capped copolymer, and adding a trialkylsilyl triflate or strong acid in excess relative to the catalyst and a hexaorganodisilazane for effecting end-capping and neutralization.

A wiring substrate (1) comprises an insulating base (10) with connection holes (11), buried conductors (12) provided in the connection holes (11) without reaching a rear surface of the insulating base (10), and wiring layers 14 connected to the buried conductors (12). The buried conductors (12) thicken the wiring layers (14), and can form aligning parts (110) on the rear surface of the connection holes (11) to be used for three-dimensional mounting structure. Each wiring layer (14) includes thin terminals (14A), wirings (14B) and thick electrodes (14C). Not only the terminals (14A) and wirings (14B) but also the buried conductors (12) are raised by the same manufacturing process. A semiconductor element (2) is attached to the electrodes (14C) of the wiring substrate (1).

A semiconductor package substrate is provided, which can meet the move toward high integration of semiconductors. A nickel layer is plated on an electroplated copper foil to form a wiring pattern. An LSI chip is mounted on the copper foil, and terminals of the LSI chip and the wiring pattern are connected by wire bonding, followed by sealing with a semiconductor-sealing epoxy resin. Only the copper foil is dissolved away with an alkali etchant to expose nickel. With a nickel stripper having low copper-dissolving power, the nickel layer is removed to expose the wiring pattern. A solder resist is coated, and a pattern is formed in such a way that connecting terminal portions are exposed. Solder balls are placed at the exposed portions of the wiring pattern and are then fused. The wiring pattern is connected to an external printed board via the solder balls.
