  • Patent number: 7651917
    Abstract: In the present invention, an npn junction is formed by circularly forming a p? type impurity region and n+ type impurity regions on a same single-crystalline substrate as a MOS transistor. Multiple npn junctions are formed apart from each other in concentric circular patterns. With this configuration, steep breakdown characteristics can be obtained, which results in good constant-voltage diode characteristics. Being formed in a manufacturing process of a MOS transistor, the present protection diode contributes to process streamlining and cost reduction. By selecting the number of npn junctions according to breakdown voltage, control of the breakdown voltage can be facilitated.

  • Patent number: 7133138
    Abstract: An optical imaging device includes a reference scanning unit offering a high signal-to-noise ratio and capable of scanning an object rapidly. An interference optical system can be realized inexpensively. In the optical imaging device, low coherent light passed through an optical coupler and another optical coupler, irradiated from an optical scanner probe, reflected from an observed point in a living tissue, returned to the optical coupler, propagated over a fourth SM optical fiber, and routed to another optical coupler shall be referred to as sample light. Light passed through an optical length variation optical system via the optical coupler and routed to the optical coupler shall be referred to as reference light. At this time, a difference between a delay time undergone by the sample light and a delay time undergone by the reference light is proportional to a difference between an optical length for the sample light and an optical length for the reference light.

  • Publication number: 20060131645
    Abstract: In the present invention, an npn junction or a pin junction is formed in an element peripheral part surrounding an element part. In addition, the same potential as that of a source electrode in the element part is applied, and a breakdown voltage of the element peripheral part is set to be always lower than that of the element part. Alternatively, resistance of the element peripheral part is lowered. Thus, breakdown always occurs in the element peripheral part, and the breakdown voltage becomes stable. Moreover, damage caused by breakdown can be prevented by eliminating occurrence of breakdown in a fragile gate oxide film. Furthermore, since the resistance is lowered, electrostatic breakdown strength is improved.

  • Patent number: 7029436
    Abstract: On the side at hand of an optical probe, a whole rotation transfer connector rotates while being supported by a ball bearing and a slide bearing and, therefore, rotation is transferred to a flexible shaft. The relative position between the flexible shaft and an optical sheath is changed in accordance with the amount of screwing of a sheath stopping member on the side at hand into an outer cylinder by an external thread portion and an internal thread portion. When the optical sheath is moved furthermore, the flexible shaft is elongated due to elastic deformation because the length of the flexible shaft is regulated by the interval between a locking part of a locking member at the tip and a shaft stopping member. A tip housing is made to contact with the locking member while tension is applied to the flexible shaft by the rear end surface in the direction of the side at hand.

  • Patent number: 6960165
    Abstract: In a light source unit, a switchable filter section in which an RGB filter and a fluorescence observation filter can be shifted into the light path is disposed in front of a lamp. When fluorescence image mode is selected, excitation light in a part of the wavelength band of the blue wavelength band is supplied to an electronic endoscope, and the excitation light which is reflected by the subject is shielded by an excitation light shielding filter situated in front of a CCD, whereby a fluorescence image can be obtained. On the other hand, if normal-light image mode is selected, then R, G, B light is supplied sequentially, and even under illumination of B light, the color component image in the wavelength bands which are not shielded by the excitation light shielding filter are captured, thereby yielding a normal-light image also, and hence making it possible to capture both a fluorescence image and a normal-light image by means of a single image pickup element.

  • Patent number: 6888119
    Abstract: A flexible shaft driven to rotate is inserted through a transparent sheath having pliability. By a fiber inserted through the inside thereof, low-coherence light is guided and is made to exit to a living-body tissue side which is an observation target through a lens and a prism forming an exit and entrance portion at the tip portion. Subsequently, the light reflected on the living-body tissue side is guided in order to produce an image. In that case, a positioning member for keeping the exit and entrance portion and the living-body tissue at a proper distance is formed at the tip portion of the sheath or the tip portion of an endoscope through which an optical probe is inserted and, therefore, a stable tomogram image can be produced.
