Inventor: YAMAMOTO TOMOHIKO
IPC: B23P19/02
Filed: 1989-04-19
Abstract: PURPOSE:To smoothly insert each of rollers into a roller groove so as to lower the frequency of errors in assembly by providing such an arrangement that an outer casing is mounted while each roller is resiliently held being inclined at a predetermined angle to the associated projecting shaft. CONSTITUTION:When a roller holder 22 which is used in the case of a flat type roller D, receives the roller D into its storage section 22a, the forward ends of bifurcated arms 25a of an engaging member 25 are engaged to both side parts of the upper edge of a rectangular flange D1a of a bearing inner casing of the roller D. Further, both arms 25a is swung upward about a pin 25c, overcoming a spring 25d, and with the use of a reaction force obtained by this swing motion, the upper edge of the rectangular flange D1a is pressed against the shaft A so as to hold the roller D which is therefore held resiliently in such a posture that the axis O of the roller D is inclined to the X axis downward toward the shaft A while inhibiting the rectangular flange D1a from being tilted in a roller rotating direction. Thus, the roller D is inserted into a roller groove E1 upon elevation of an outer casing E.

Title: Method and device for measuring ion current density in surface analysis
Inventor: SUZUKI TOSHIKO
IPC: H01J37/04
Filed: 1990-04-16
Abstract: PURPOSE:To provide precise measurability for the ion current density in any desired place by cutting off the central part of a metal plate, irradiating the surfaces of these plate segments with ions while a pos. potential is impressed to them individually, measuring the amount of ion current flowing in the central part, and determining the ion current density. CONSTITUTION:The central part of a metal plate is cut off, and the surfaces of these produced plate segments 11, 12 are irradiated with an ion beam IB at an angle theta in the condition that the same pos. potential is impressed. This suppresses emission of secondary electrons to be generated by ion irradiation, and thereby there is no increment in the specimen current, and a current due to only the ions cast onto the surface of the plate segment 11 flows through an ammeter 15. Because the area of the plate segment 11 is constant for all irradiation angles with ion beam IB, the ion current density is determined by dividing the reading on the ammeter 15 with the previously determined area of the plate segment 11. This provides precise measurability for the density in any desired place.

Title: Method of molding emboss type gasket
Inventor: ROBAATO EI DEKOAA
IPC: F16J15/12
Filed: 1989-04-19
Abstract: PURPOSE: To align a bead and an embossment accurately by applying a relatively incompressible elastomer sealing material against one of two major surfaces of a gasket body with sufficient pressure and in a manner deforming both of the major surfaces so that an embossment is defined there encircling a hole and comprising a projection and an indentation. CONSTITUTION: A gasket body 12 is disposed between opposed and relatively displaceable surfaces 46 and 48 of dies 42 and 44 so as to be formed thereon with an embossment 30 placed in position. A major gasket surface 14 from which the embossment 30 projects is placed face-to-face with the die 44 with an indentation 50. A relatively incompressible fluid elastomer material is applied against another major gasket surface 16 on the opposite side of the indentation 50 through a runner opening 52 with relatively high pressure. This high-pressure application of the sealing material deforms relatively small areas of the planes of both major surfaces 14 and 16, or curves the gasket body 12 down into the indentation 50, to produce the embossment 30 encircling an opening 22. The sealing material then remains there as a bead 36 that fills an indentation 34.
