Title: Wide angle lens
Inventor: HONDA AKIKO
IPC: G02B13/18
Filed: 2001-12-19
Abstract: PROBLEM TO BE SOLVED: To obtain a wide angle lens of satisfactory performance in visible light and near infrared light regions even though the lens is small and inexpensive and tolerance is also loose. SOLUTION: This wide angle lens successively comprises a first lens 11 being a double-concave lens having negative power and a second lens 12 being a double-convex lens from an object side. One or more lens surfaces are aspheric, and satisfies the following conditions: 1<|r4|/r3<3 and D2<1.5f when the radius of curvature of the second lens on the side of the object is defined as r3, the radius of curvature of the second lens on the image side as r4, and the focal length of the entire system as (f). The wide angle lens requires only two lenses while the distance between the lens surfaces is small, thereby making the lens small. Since the first lens is a double-concave lens, the refraction power of the image side is distributed to an object side, the curvature of the image side can be made weak, and the wide angle lens is made strong in assembling tolerance.

Title: Electron beam analyzer
Inventor: MARUI TAKAO
IPC: G21K5/04
Filed: 2001-12-20
Abstract: <P>PROBLEM TO BE SOLVED: To improve resolving power for pulse-height measurement using an energy distributed X-ray detector.  <P>SOLUTION: In this electron beam analyzer, when one of X-ray is detected, EDX 5 generates an electrical pulse, and the pulse is amplified by an amplifier 6, and then its height is converted to a digital value by an A/D converter 7 and taken in a histogram memory 10. Since the height of the pulse generated by the EDX 5 is proportional to the energy of the detected X-ray, the digital output of the A/D converter 7 shows the energy of the X-ray, while the strength of the X-ray is measured by counting the number of the X-ray per unit time. Acceleration voltage data to an electron beam source 2 are also inputted to an amplification factor controller 8, and then the amplification factor controller 8 is set as an amplification factor of the amplifier 6, being inversely proportional to the acceleration voltage in order to make match the pulse with maximum energy to the maximum input voltage of the A/D converter 7. As a result, the dynamic range of the A/D converter 7 is used fully without wasting the dynamic range.  <P>COPYRIGHT: (C)2003,JPO
