Title: Apparatus and method for measuring raman spectrum
Inventor: ISHIZUKA NORIO
IPC: G01N21/65
Filed: 1995-06-19
Abstract: PURPOSE: To specify a measuring position in a remarkably minute pattern by setting a probe and a displacement-measuring device sideways of an objective lens. CONSTITUTION: A sample 13 is placed on a stage 10 and moved to below an objective lens 4, to which a light of a light source 1 is cast. A reflecting light is detected at 5 and a Raman spectrum-measuring position 14 is schematically determined. Three or more marks 15 of 1-2 microns are provided in the vicinity of the position. Thereafter, the stage 10 is moved to bring the sample 13 close to below a probe 8 until an interatomic force acts. The sample 13 is scanned within a horizontal plane. The probe 8 shifts at the scanning time because of a change of the interatomic force due to an irregular surface of the sample 13. A shift- measuring device 9 measures the shift and the stage 10 is controlled by 11 to make the shift constant. The controlling amount and the scanning position are made to correspond each other and an image of the surface of the sample 13 is obtained. Distances L1 -L3 between the position 14 and a center of each mark 15 are measured from the image. The sample 13 is moved to below the lens 4 and a position of the center of the mark 15 is recognized by 5. The position 14 of the sample is then moved by the distances L1 -L3 . In this manner, the position 14 can be specified with approximately half an observation resolution of a metal microscope, spectrally analyzed by 6 and detected by 7.

IPC: B41J2/175
Filed: 1986-06-30
Abstract: PURPOSE:To obtain a recording apparatus not damaging a recording a head by the movement of a cap, by detecting whether the cap is present at a spaced- apart position by a detection means when a power source is closed and allowing a carriage to run to a home position. CONSTITUTION:A detection mechanism 48 is constituted so that an eccentric cam disc 48 and a detection switch 48b to be turned ON and OFF by the large diameter part of the eccentric cam disc 48a are mounted to the shaft 42a of a follower gear 42. When the detection switch 48b is turned OFF, it is detected that a cap holder 28 is present at a first position spaced-apart from a carriage and, when turned ON, it is detected that the cap holder 28 is present at a second position. When a power source is closed, it is judged whether the cap holder 28 is present at the first position. When the cap holder 28 is at the first position, the carriage 14 runs toward a home position and, when the cap holder 28 is absent at the first position, the carriage 14 is moved to the first position and subsequently allowed to run toward the home position. By this method, the unnecessary contact between a cap device and a recording head is prevented.

Abstract: PURPOSE:To improve the accuracy of the width of a working grove by a method wherein the working speed of the wire cut electric discharge machining is controlled by working it out from a working current, the width of the working groove and the thickness of a work piece. CONSTITUTION:A pulse voltage is impressed to a wire electrode 2 and the work piece 1 while the electric discharge current, flowing through a working clearance, is detected by a detector 9. A short-circuit detector 10 detects the voltage of the working clearance to decide a short-circuit and closes a switch 11 only upon the normal electric discharge to transmit a current detecting signal to a smoothing circuit 12. The output of the smoothing circuit 12 expresses a real working current Iw and the working speed F is controlled by working out it by a formula F=K1(Iw-K2h)/hd, wherein, (d) is the width of the working groove, (h) is the thickness of a work piece, K1, K2 are constants. The width of the working groove may be kept in constant by controlling the working speed in such a manner.
