[PROBLEMS] To provide a fixing structure capable of adjusting the dimensions in the vertical direction of a vibration generating device including a circuit board in combination with the circuit board without reducing the size or the diameter of the vibration generation device. [MEANS FOR SOLVING PROBLEMS] A fixing holder in a holder shape for holding or including at least a part of the outer circumference of a vibration generating device has an inner circumferential surface substantially identical to the external shape of the vibration generating device. Groove-like rail parts are provided partially in the outer circumferential surface of the holder at the opposite ends thereof in the same linear direction, and the side end part of a notched circuit board or a part on the housing side of the apparatus is inserted into each of the groove-like rail parts, thus holding and securing the vibration generating device at an arbitrary vertical position against the surface of the circuit board in the apparatus.

[Problems] A surface mount-type vibration motor and an installation structure for a surface mount-type vibration motor, where soldered portions are prevented from separating from a circuit board without requiring any design change in a vibration motor body.[Means for Solving the Problem] A section where a motor holding section 31 of a motor holder 30 and motor support sections 32 of the motor holder 30 are connected is bent in an arc shape having elasticity to form the motor holder 30, the motor holding section 31 holding a vibration motor body 2 to which an elastic holder 8 is attached, the motor support sections 32 being arranged along a circuit board 3. First contact sections 52 and second contact sections 53 are formed in the connection section such that distal ends of the first and second contact sections are of a band-like shape projecting toward the inside of the vibration motor body 2. The motor holder 30 reduces a load applied to portions where the surface mount-type vibration motor 1 is soldered to the circuit board 3 and also improves bonding strength.

A medical stereo observation system includes a stereo imaging unit producing a first image for a left eye and a second image for a right eye that mutually have parallax and a stereo display unit capable of displaying stereoscopically the images produced by the stereo imaging unit. The stereo imaging unit has a first imaging optical system producing the first image for the left eye and a second imaging optical system producing the second image for the right eye, and focal positions of these imaging optical systems are located far away from the intersection of optical axes of the imaging optical systems, viewed from the stereo imaging unit. Whereby, a large-depth space can be comfortably observed in a wide range and a viewer can observe an observation object without bringing about a feeling of fatigue.
摘要:
A stereoscopic observation apparatus is disclosed that includes an image projector that projects left and right eye images to an image surface, with the images being substantially overlapped at the image surface. The images may be viewed auto stereoscopically by virtue of an imaging element having positive optical power that conjugates the apertures to observation exit pupils. A holographic optical element that has little or no optical power is positioned at or near the image surface for the purpose of dispersing the light in the non-zero diffracted orders. The amount of dispersion caused by the holographic optical element over the wavelength range 450 nm-650 nm for diffracted light of the first order is less than or equal to one-half the angular amount that each first-order diffracted beam is diffracted from the direction of propagation of the zero-order beam that passes straight through the holographic optical element.
摘要:
In a sync detector, a baseband signal is segmented into a plurality of successive bit sequences so that the bits of each sequence are shifted by one bit position with respect to the bits of adjacent sequences. On a bit-by-bit basis, mismatches are detected between each input bit sequence and a predetermined bit sequence and the detected mismatches are counted to produce a mismatch count. A first comparison is made between the mismatch count and a reference value to determine that a sync code is detected if the mismatch count is equal to or smaller than the reference value, and a further comparison is made between successively produced mismatch counts to determine that a sync code is detected when the later of the successively produced mismatch counts is equal to or smaller than the earlier one. The first comparison is repeated when the later mismatch equals zero.
