Title: Rotary contact probe
Inventor: SAITO MASAHIKO
IPC: G01R1/067
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a rotary contact probe that has a simple structure and high durability and bears comparison with conventional produces in performance. SOLUTION: The probe main body 2 of a contact probe 1 is constituted of a tip part 2a adapted to butt against a conductive contact object and a cylindrical part 2b, which is formed with a groove 2c extended at an angle of about four degrees to the axis. The contact probe 1 further includes a sleeve 3 that is formed on its inner surface with a projection 8 adapted to be fitted in the groove 2c of the probe main body 2. Because the tip part 2a and the sleeve 3 are connected together by means of a spring 7, when the probe main body 2 is pressed against an object or conductive contact surface, the sleeve 3 rotates along the groove 2c of the probe main body 2 to offer reliable contact of the contact probe 1 with the contact surface. Since the probe main body 2 rotates only about fifteen degrees for one stroke in the groove 2c in the movement, even if a lead wire 6 is lead out direct from the probe main body 2 as the energization method, the lead wire 6 never has such a twist as breaking itself.

Title: Light cvd device
Inventor: KATSURAYAMA TAKAO
IPC: H01L21/26
Filed: 1990-11-16
Abstract: PURPOSE:To contrive uselessness of a mask, a reduction of product costs, efficiency of design and trial manufacture, and easiness of cubic patterning formation by a method wherein a light can selectively be emitted on a substrate by using a liquid crystal shutter. CONSTITUTION:A light can be transmitted into a liquid crystal shutter 8 in a ring form, and when a emitted light from a light source 9a is emitted, a light is transmitted in a ring form to be reduced by a lens 7 to emit on an upper surface of a substrate 1. Next, when the emitted light from a side light source 9b is incident on a cylindrical lens 10, it becomes a plane light to emit on an upper portion of an upper surface of the substrate 1. In this state, when material gas is flown onto the upper surface of the substrate 1 from a material gas bomb 4, the material gas generates a dissolving reaction to form a ring-like film on the substrate 1. Inert gas is flown onto a lighting window surface from an inert gas bomb 5 so that the material gas diffuses and does not form a film on the lighting window of a vacuum vessel 3, then the unnecessary gas is discharged by a vacuum pump 6. Thus, this makes unnecessary to make a mask, reduces production costs, makes efficient design and trial manufacture, and simplify cubic pattern formation.

Title: Feedback amplifier circuit
Inventor: KATAYANAGI TETSUO
IPC: H04B10/40
Filed: 1994-12-15
Abstract: PURPOSE: To adjust gain against a change in frequency characteristics due to the dispersion of elements by controlling the frequency band width of a feedback amplifier circuit by a 1st transistor(TR) and varying the level of an output signal by a 2nd TR. CONSTITUTION: When a photodetector 1 is irradiated with light, a current flows into FETs 41, 42 in a feedback circuit 40, the drain current of an FET 31 in a feedback amplifier circuit 30 is increased and the potential of the gate G and source S of an FET 34 and the potential of the gate G of an FET 35 are reduced. Thereby output voltage Vout obtained from an output terminal T is changed in a direction reverse to the gate potential of the FET 31. Since the potential of the terminal T is reduced due to the drop of the voltage Vout, the rise of the gate potential of the FET 31 is suppressed. When the cathode current of the photodetector 1 is reduced, the output voltage Vout is increased.  Thereby, when the resistance value Rf of the circuit 40 is reduced, a feedback amount is increased, high band interruption frequency is increased and the frequency band of the circuit 30 is extended and vice versa.

Abstract: PROBLEM TO BE SOLVED: To visually confirm a developed drawing mesh and reduce the load of drawing by manual work by determining the actual lengths of three sides of each triangular within a triangular mesh, and developing and drawing each triangular having three sides having these lengths so that an overlapping is not caused on the same plane. SOLUTION: A data processing device 3 has a TIN processing means 5, and the TIN processing means 5 expresses the terrain by a triangular mesh by drawing a triangle having the measuring point as the apex. The triangle constituting the triangular mesh based on the TIN processing contains a Z-axial coordinate component, and the actual length of each of three sides of this triangular is determined by a side length measuring means 9, a triangular corresponding to the surface area having three sides corresponding to this actual length is determined by a terrain development drawing processing means 7, and successively connected one by one. When the other triangle is connected to a triangle, an overlapping preventing means 10 shifts and develops it so as not to overlap the previous triangle.

Title: Method and apparatus for detecting photo-acoustic signal
Inventor: NAKADA TOSHIHIKO
IPC: G01N29/00
Filed: 1993-12-13
Abstract: PURPOSE:To decrease the fluctuation of an interference signal and detect a photo-acoustic signal highly accurately even to a sample having rough surface by using the same optical path for the optical path of probe light and the optical path of reference light and using the DC component of the Fourier transformation image of the reflected light, in order to detect the displacement caused by thermal expansion based on a photo-acoustic effect or an optical heat effect. CONSTITUTION:The same optical path is used for the optical path of a probe 69 and a reference optical path 70 by using a double-focal-point lens. In the probe light 69, a light condensing position 71 on the surface of a sample 43 and a photoelectric conversion element 57 have the image focusing relationship. In the reference light 70, the Fourier transformation position for the surface of the sample 43 and the photoelectric conversion element 57 have the image focusing relationship. Therefore, the probe light 69 holds the phase change caused by the displacement based on the periodic thermal expansion caused at the light condensing position 71. Meanwhile, the reference light 70 has the Fourier transformation image data of the phase distribution based on the roughness and the minute irregularities of the surface of the sample 43. Among the converted images, the high-frequency component is screened. Therefore, only the DC component contributes to the interference as the reference wave front. The wave front, wherein the effects of the roughness and the minute irregularities are decreased, is obtained.
