Title: Structure of x-ray spectroscopic detecting part
Inventor: NIWA NAOMASA
IPC: G01N23/00
Filed: 1990-09-21
Abstract: PURPOSE:To make it possible to arrange many spectroscopic detecting parts around a sample stage by attaching spectroscopic crystals and detecting devices at the halfway parts of a plurality of linear bodies which are hooked between supporting plates arranged at the upper and lower parts of a detecting region through attaching members in a free slanting pattern. CONSTITUTION:Supporting plates having the disk shapes are arranged at the upper and lower parts of an X-ray detecting regions. Four linear bodies are arranged in one line on many lines of radii with the position of a sample as the center for every spectroscopic detecting part. A spectroscopic crystal 1 is supported at the halfway parts of two bodies 51 and 52 closer to the sample among one set of the linear bodies through clamps 6 and a holder 7. The clamps 6 are pivoted to the holder 7 so that the holder is freely slanted. A detector 2 is supported with two outer bodies 53 and 54 by the same way. The linear bodies 51(54) can be moved up and down by the rotary driving of female screws 10. Thus, the slant attitudes of the crystal 1 (detector 2) are changed. The spectroscopic detecting part occupies only a space corresponding to the size of the part itself at the position of the attaching height. In the planar view, many detecting parts can be arranged at the narrow pitch wherein the portions of the detecting parts are overlapped.

Title: Stainproof optical component and exposure device provided with same
Inventor: MURATA TAKESHI
IPC: G02B1/10
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To provide an optical component exhibiting a high stainproof effect and excellent in uniformity in the thickness distribution, mechanical strength and adhesion to a substrate without affecting a spectral transmittance by providing a base material, on the uppermost layer thereof, with a polymer film formed from a perfluoroalkyl group-containing perfluorocycloalkane as a starting material by a plasma polymerization method. SOLUTION: A polymer film formed comprises a fluorocarbon, a substance having the smallest absorptivity coefficient in the ultraviolet region. The polymer film is caused to have a thickness of 50 Åor less when used simply as a stainproof film. When an antireflection function and other optical performances are desired in addition to stainproof properties, a thick film is formed. For example, when a light having a wavelength of 350 nm or less is intended, the film is caused to have a thickness of about 1,500 Å or less. Concrete examples of a perfluorocycloalkane employed as a starting material are represented by formula I to III. Though glow discharge is usually employed in the plasma polymerization, there is no limitation in this process and arc discharge can be employed.

IPC: H03K5/1252
Filed: 1985-11-13
Abstract: PURPOSE:To eliminate effectively not only random noise but periodical noise by delaying a sampling pulse in a delay device which delays the pulse by a time corresponding to a random function value generated by a random function generator. CONSTITUTION:A sampling signal (a) is applied to a random function generator 10 and a delay device 11. The generator 10 generates the random function value each time when the signal (a) is received, and this value is normalized to a value which does not exceed the period of the signal (a) and is sent to the delay device 11. The delay device 11 outputs a sampling pulse signal a' obtained by delaying the signal (a) by a time corresponding to this value. The signal a' is not only applied to a gate circuit 3 but also delayed by a delay circuit 8 and is applied to a shift register 4 as a shift register clock signal b'. A digital input signal is applied to the circuit 3 through a filter 2 and passes the circuit 3 by the signal a' and is loaded to the register 4. AND among output signals of respective Q terminals of FFs FF1-FFn of the register is operated by an AND circuit 5, and the output is outputted from an output terminal as an output signal where noise is eliminated.

Title: Stepped pulley and its manufacture
Inventor: MATSUOKA TAKESHI
IPC: B21D53/30
Filed: 1984-11-30
Abstract: PURPOSE:To reduce weight of a stepped pulley and to improve durability of the pulley by slitting a disklike web into two pieces in the radial direction to form a couple of rims and by forming V-shaped grooves on the peripheral surface of the rims respectively. CONSTITUTION:A disklike blank Q formed by punching a steel plate is held between backing dies 11a and 11b and is rotated. A slitting roller 12 is pressed against the blank Q. The roller 12 rotates synchronously to form a slit groove 13 on the blank Q. An expanding roller having a taper-shaped section is pressed against the slit groove 13 to expand it. Thus a couple of stepped webs 8a and 8b which have a different diameter from each other are formed. Then, the blank Q is held between rotating backing dies 17a and 17b and multiple V grooves 9a and 9b are formed by a forming roller 16. Use of a thin blank plate reduces weight of the pulley and existence of a web at the center of the pulley increases durability of the pulley.
