An oral airway, which is used by being inserted into the mouth of a patient who is suffering from unconsciousness or has lost consciousness to secure an airway of the patient, is adapted to be used with a tube to be inserted into the trachea of the patient through the mouth thereof. The oral air way includes a main body, and an insertion part provided on the main body. The insertion part is adapted to be inserted into the trachea of the patient through the mouth thereof so that an appropriate portion of the insertion part at the side of the distal end thereof comes into contact with the root of the tongue of the patient to secure the airway of the patient. The insertion part includes a guide groove for guiding the tube when the tube is inserted into the trachea of the patient, and the guide groove has a structure from which the tube can be separated after the distal end of the tube has been inserted into the trachea of the patient.

An intubation assistance instrument which is used by being inserted into the trachea of a patient through the mouth thereof includes an insertion section having a straight portion with a tip part and a curved portion continuously extended from the tip part of the straight portion. The insertion section is formed with a groove along a longitudinal direction thereof. The curved section has an inner wall part and an outer wall part which define the groove, and the outer wall part is formed with a cut out portion other than a tip part of the curved portion. The intubation assistance instrument and an intubation assistance apparatus provided with the instrument make it possible to carry out intubation operation with simple operation easily and safely.

An intubation assistance apparatus includes a main body and an intubation assistance instrument detachably mounted to the main body. The intubation assistance instrument has an elongated insertion section for insertion into the trachea or its vicinity of a patient from the mouth. The insertion section of the intubation assistance instrument is provided with a groove for leading an intubation tube to the trachea of the patient and a scope guide bore for receiving a laryngoscope with a CCD and a white LED. A distal end portion of the scope guide bore is fluid-tightly (air-tightly) sealed. The scope guide bore is fluid-tightly (air-tightly) sealed in its entirety in a state that the intubation assistance instrument is mounted to the main body. A plate-like tongue piece protruding forward and having optical transparency is formed on a distal end portion of the insertion section.
摘要:
A phase modulation element according to the present invention has a first area having a first phase value based on a phase modulation unit having a predetermined size and a second area having a second phase value based on the phase modulation unit having the predetermined size, and each phase distribution is defined by a change in area shares of the first area and the second area depending on each position.

The present invention comprises a light modulation optical system having a first element which forms a desired light intensity gradient distribution to an incident light beam and a second element which forms a desired light intensity minimum distribution with an inverse peak shape to the same, and an image formation optical system which is provided between the light modulation optical system and a substrate having a polycrystal semiconductor film or an amorphous semiconductor film, wherein the incident light beam to which the light intensity gradient distribution and the light intensity minimum distribution are formed is applied to the polycrystal semiconductor film or the amorphous semiconductor film through the image formation optical system, thereby crystallizing a non-crystal semiconductor film. The pattern of the first element is opposed to the pattern of the second element.
摘要:
An apparatus for producing a hologram mask. The apparatus includes a first object light at least partially transmittable through a first original mask having a light transmitting screening pattern, and a first reference light having a first phase difference between it and the first object light. The first object and reference lights cause interference patterns to be recorded a hologram recording material, as do a second object light at least partially transmittable through a second original mask having a light transmitting screening pattern, and a second reference light having a second phase difference between it and the second object light where the second phase difference is not the same as the first phase difference. The resulting first and second original mask images recorded in the hologram recording material can be simultaneously replayed to produce an exposed pattern approximating an exposed pattern of a non-holographic phase shifting photomask.
摘要:
A problem of a decrease in transmissive light, which partly occurs at a boundary between two polarization modulation regions of a polarized phase shift mask, is solved. A photomask for use in an exposure apparatus which forms an exposure pattern by illumination includes at least two polarization modulation regions which produce mutually incoherent polarized light components and adjoin each other, at least two phase modulation regions which impart a phase difference of 180° and adjoin each other, and amplitude modulation regions which decrease transmittance. A contact line between the polarization modulation regions and a contact line between the phase modulation regions are located at a corresponding position, and the amplitude modulation regions are provided on both sides of the common contact line, with a predetermined distance from the common contact line.
