Abstract: An endoscope is provided with a water proof cover on its eyepiece portion or its connector portion to be connected with a light source system. The water proof cover is provided with a smooth engaging face on the internal periphery near its open end to be liquid tightly engaged with a packing ring mounted on the endoscope. There is provided a protective cover above the packing ring to prevent the ring from being damaged while the cover is removed from the endoscope. In a preferred embodiment, the water proof cover is provided with a protective sleeve which is slid into the protecting position to cover and protect the smooth engaging face while the water proof cover is removed from the endoscope. In a further preferred embodiment, the water proof cover is made into such a form as to enable the diopter ring to be rotated with the cover mounted on the endoscope.

Abstract: A chuck mechanism for a dental handpiece holds a columnar rotary tool for dental care rotatably with an annular rotor of the dental handpiece. The columnar rotor tool is concentrically detachable to the annular rotor which is rotatably attached to a head part of the dental handpiece. The chuck mechanism has an annular chucking member with a cylindrical base part into which the annular rotor is integrally fitted and an elastic chucking piece having a chucking pawl for engaging with a locking groove formed at a base end of the rotary tool. The chuck mechanism enables the rotary tool to be easily removed from the annular rotor by elastically deforming the elastic chucking piece against elastic force of the elastic chucking piece to disengage the chucking pawl from the locking groove.

Abstract: A vehicle presence notification apparatus includes a modulating section to modulate an ultrasonic wave functioning as a carrier wave according to an audible sound; and a speaker to generate the audible sound as a notice sound by emitting the modulated ultrasonic wave in the air. As proceeding in the air, the modulated ultrasonic wave is gradually demodulated to thus become the audible sound. The audible sound posterior to the demodulation has a significant directivity like the ultrasonic wave. The notice sound is thus conveyed mainly to a pedestrian who is present in a dangerous area range where a danger needs to be taught. The sense of discomfort due to the notice sound is reduced for a pedestrian, who is not present in the dangerous area region or a person who is inside of another vehicle.

Abstract: A reference voltage generating circuit includes a current generating section, a voltage generating section, a voltage dividing circuit, and a synthesis section. The current generating section generates a first current having a positive temperature coefficient. The voltage generating section generates a voltage having a negative temperature coefficient. The voltage dividing circuit divides the voltage of the negative temperature coefficient, generated by the voltage generating section. The synthesis section generates a voltage which is the sum of a terminal voltage obtained on causing the first current through a resistor and a voltage obtained on dividing the voltage having the negative temperature coefficient by the voltage dividing circuit, and outputs the sum voltage generated as a reference voltage.
