Filed: 1985-10-14
Abstract: PURPOSE:To shorten the full length of a rotor and lighten its weight, by forming a magnet for a frequency generator, in a ring shape, and by fixing the one side of the ring-formed open end to come in contact with the end face of a core. CONSTITUTION:When a commutator 4 is set on the one end side of a rotor core 2 wound up with a coil, and a magnet (FG magnet) 10 for a frequency generator is fitted on the opposite side, then the magnet 10 for the frequency generator is formed in a ring shape. The one side open end of the magnet 10 is arranged to be fixed on the end surface of the core 2 in contact with each other so that a coil end 5 may be contained in the ring-shaped hollow section. By this configuration, the axis-directional length of the coil end 5 is overlapped with that of the magnet 10, and so the full length of a rotor can be shortened by that length, and the weight of the magnet 10 can be lightened.

IPC: E02D3/10
Filed: 1983-12-01
Abstract: PURPOSE:To determine the setting position of draining materials as well as to detect the settling amount of the draining materials by layer group by a method in which draining materials with an object to be detected are driven in the ground, and a tube with a sensor is driven in a position adjacent to the draining material.

IPC: F25D27/00
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To enlarge a commodity-containing space and to facilitate maintenance by providing a flat type fluorescent lamp in a showcase having a storage chamber constituted to display a commodity in a heat insulation wall. SOLUTION: The showcase is constituted to mount a mounting plate 34 on a front end of a top wall 2B of a heat insulation wall and to cover a front surface of the insulation wall a front surface of a discharge port 16 of the insulation wall from a top surface of the insulation wall with the plate 34. A recess 35 opened at the front surface of the plate 34 is formed at the front surface of the plate 34, and a flat type fluorescent lamp 35 is mounted in the recess 36. Since a width size of the lamp 35 is thin, the lamp can illuminate a front surface of the showcase without requiring a space for mounting the lamp. Thus, the width size of the plate 34 can be reduced forward from the cold air discharge port 16, and a storage chamber can be enlarged in association with the reduction in the width size. A mounting member is simplified to improve assembling operability and to reduce a cost.

Title: Removing method of natural oxide film
Inventor: KADOMURA SHINGO
IPC: H01L21/3065
Filed: 1991-08-15
Abstract: PURPOSE:To prevent the anisotropic shape of a continuous hole from being degraded when removing the natural oxide film at the bottom of the continuous hole opened to a multilayered insulating film. CONSTITUTION:A contact hole 8 is opened in a four-layered interlayer insulating film 7 on a silicon substrate. Side wall protective films 10 of a sulfur nitride having a polymeric (SN)x as its main component are formed on the side walls by the plasma CVD which uses a mixed gas of S2F2/H2/N2. Then, the SiOx, natural oxide film 9 is removed in an HF atmosphere. The sulfured nitride side wall protective films 10 protect a highly reactive PSG layer 4 and BPSG layer 6 from any attack of the F* in order to prevent the generation of an undercut and others, but the films can be easily dissolved or removed by sublimation if the wafer is heated approximately to 150 deg.C. Therefore, there is no fear that any particle contamination or the reduction of the aperture diameter of the contact hole occurs.

Abstract: PURPOSE:To add the original-point/fixed-point detecting functions to a hologram scale by sticking a hologram lattice plate and the scale so as to cover the surface where the holographic diffraction grating is formed. CONSTITUTION:A surface where a holographic diffraction grating 2 of a holographic diffraction grating plate 1 is formed and a surface where an original- point/fixed-point detecting scale 6 of a protecting substrate are arranged so that the both surfaces face to each other.
