Title: Piston ring assembler
Inventor: SUZUKI MANABU
IPC: B23P19/02
Filed: 1994-03-30
Abstract: PURPOSE:To keep off the assembling miss of a piston ring by compensating any slippage in this piston ring at the upper edge position of a diametral expanding guide member. CONSTITUTION:A light projector 51 projects a plane-form laser beam with the specified breadth B in the vertical direction from one side of a diametral expanding guide member 4, while a light receiver 52 receives this laser beam at the other side of the guide member 4. In the case where a top face of a piston ring 21 is accorded with an upper edge 4d of the guide member 4, the light receiver 52 receives the laser beam of breadth (b), and in the case where the piston ring 21 is projected as far as DELTAt from the upper edge 4b, the light receiver 52 receives the laser beam as far as breadth b-DELTAt. Since this light receiver 52 outputs such a signal as conformed to the light receiving value, the projection value DELTAt is measured on the basis of the output signal of the light receiver 52.

Title: Magnetoresistance element
Inventor: ENDOU MICHIKO
IPC: H01L43/08
Filed: 1990-03-13
Abstract: PURPOSE:To detect a change in a magnetic field without magnetically saturating patterns partially even when an applied magnetic field is not uniform on the same MR element chip by a method wherein widths of the patterns of a ferromagnetic thin film are made partially different so as to correspond to the position of a magnetic-field source. CONSTITUTION:Widths of parts 3a, 3b of a pattern 3 and those of parts 4a, 4b of a pattern 4 are made different. For example, the pattern width of the part 3a is set to 10mum, the pattern width of the parts 3b and 4b is set to 14mum and the pattern width of the part 4a is set to 18mum. The pattern widths are set properly so as to correspond to the position of a magnet 2 as a magnetic- field source. When the pattern widths of an MR element chip 1a are formed in this manner, the sensitivity to a change in a magnetic field differs at the parts 3a, 3b, 4a, 4b of the patterns 3, 4; the sensitivity at the part 4a becomes 1.8 times that of the part 3a. Thereby, even when an applied magnetic field is not uniform on the MR element chip 1a, it is possible to avoid that a magnetically saturated part is caused.

Abstract: PURPOSE:To implement Bi-CMOS/ECC level conversion and to facilitate skew adjustment without increasing an input capacitance of a MOSTR by adjusting an ON-resistance of P-channel and N-channel transistors (TRs) each comprising a buffer circuit. CONSTITUTION:When an input IN reaches an H CMOS level, a P-channel TR MP1 of a 1st buffer circuit and an N-channel TR MN2 of a 2nd buffer circuit are respectively turned off/on. Then the N-channel MOSTR MN1 of the 1st buffer circuit and N-channel TRMN3 of a 3rd buffer circuit are turned off and P-channel TRs MP2, MP3 of the 2nd and 3rd buffer circuits are turned on and an output goes to a Bi-CMOS H level. In this case, levels at nodes A, B for skew adjustment from H to L and from L to H depend only on the ON-resistance ratio of the TRMP1, MN1 and TRMP2, MN2, the conversion of the Bi-CMOS/ECC level is implemented without use of TRs having a large input capacitance and skew adjustment is facilitated.

Title: Method for correcting mask defect
Inventor: TANAKA MARIKO
IPC: G03F1/00
Filed: 1987-03-17
Abstract: PURPOSE:To permit easy correction of a mask having a void defect by projecting a laser beam on the point corresponding to the defect of a metal-contg. polymer film formed by coating a metal-contg. polymer on said mask, then dissolving away the metal-contg. polymer of the part not irradiated with the laser beam by a solvent. CONSTITUTION:The metal-contg. polymer is coated on the mask 20 having the void defect 23 to form the metal-contg. polymer film thereon. The laser beam 25 is projected on the point corresponding to the defect 23 of the metal- contg. polymer film 24 to remove the org. matter in the metal-contg. polymer film. A metallic film 26 is formed of the remaining metallic component. The metal-contg. polymer film 24 in the part not irradiated with the laser beam is then dissolved away by the solvent. Since there are no metallic films on the surface of the metal-contg. polymer film 24, generation of dust at the time of dissolving away the metal-contg. polymer film 24 is obviated. The correction of the void defect of the mask is thereby permitted without contaminating the mask, i.e., without having the possibility of forming fresh defects.

Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To precisely carry out sizing by displaying a standard line on the surface of a sighting apparatus and irradiating the standard line with laser beam of a standard for laser sizing. SOLUTION: This sighting apparatus 6 is a square bar 7 in a prescribed length, a slope 8 extended downward is formed in the end part of the front face and a step 9 rising in a prescribed size is formed in the rear end. Moreover, a standard line 10 is displayed on the surface of the sighting apparatus 6, on the slope 8, and on the side face of the step. Laser beam of a standard for laser sizing is applied to the standard line 10 to carry out sizing. In other words, in the case the standard line 10 is aligned in approximately the center of the laser beam, since the thickness of the standard line 10 is about 1 mm or thinner while the thickness of the laser beam is about 2-3 mm, the standard line 10 can be positioned in the center. Consequently, positioning at a gradation mark of a scale can easily be carried out by laser beam.  By employing the standard line 10 as a standard, alignment at a gradation mark of a scale is carried out to precisely carry out measurement.

Filed: 1990-03-12
Abstract: PURPOSE:To make stabilization of tape traveling and improvement in reliability by specifying the value obtd. by dividing the sheet resistance value of a tape traveling surface and the sheet resistance value of the other surface and the value of the surface resistance value. CONSTITUTION:A conductive layer 2 is provided on at least one surface of a plastic sheet 1 which is the base material of the slip sheet. The value obtd. by dividing the sheet resistance value A of the tape traveling surface by the sheet resistance value B of the other surface is <=1 and the value of the sheet resistance value B is >=10<8>OMEGA. The surface of the slip sheet formed with the conductive layer 2 is used as the tape traveling surface. The surface not formed with the conductive layer 2 is, therefore, the wall surface side of a cassette half at the time of assembly to the cassette. The improvement in the reliability of the slip sheet is not expected if the value obtd. by dividing the sheet resistance value A of the tape traveling surfaced by the sheet resistance value B of the other surface is larger than 1. The improvement in the slip sheet is not expected if the sheet resistance value of the other surface is smaller than 10<8>OMEGA. The stabilization of the tape traveling and the improvement in the reliability are made in this way.
