Title: Two-component developer
Inventor: SHIMOYAMA HIROSHI
IPC: G03G9/08
Filed: 1994-09-07
Abstract: PURPOSE: To ensure superior transfer efficiency and heat fixability, to stably form a copied image having the required density over a long time and to improve anti-offsetting property, spending resistance, pulverizability at the time of producing a toner and the stability of a charged state at high humidity. CONSTITUTION: This two-component developer contains a toner and a carrier. The toner contains toner particles contg. a prescribed fixing resin and a prescribed amt. of magnetic powder. The particles of the carrier contain a thermoplastic resin and high resistance magnetic powder having a prescribed particle diameter. The thermoplastic resin contains a resin having cationic polar groups and the high resistance magnetic powder has prescribed resistivity. This developer does not contain any electrostatic charge controlling agent. Since the electrostatic chargeability of the toner and carrier of this developer is, however, satisfactory and the toner particles bond satisfactorily to the particles of the carrier, spending is not caused and no toner is scattered.  The force required to mix and stir this developer is small, superior transferability with a magnetic brush is ensured and sliding friction to a photoreceptor is reduced. The particles of the magnetic carrier hardly cause aggregation or sticking to the surface of the photoreceptor.

Title: Method and device for detecting end of material to be cut
Inventor: MURAKAMI NAOHIKO
IPC: B23K26/00
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To accurately detect the end of a plate material even if the shape of the end is deformed in the material. SOLUTION: In a state where a plate 7 to be cut is placed on a cutting base 8, cutting is started for the plate 7 by holding a laser cutting torch 1 near the end of the plate 7 with a specific space apart from the plate while an assist gas is supplied; then, a micro differential pressure detecting sensor 6 successively detects the inner pressure of an injecting pressure collecting cover 5, sending it to the comparator of a plate end detecting part.  During the movement of a laser cutting torch 1, the comparator makes a comparison between the inner pressure of the injecting pressure collecting cover 5 detected by the micro differential pressure detecting sensor 6 and a preliminarily set threshold value; and, if the inner pressure is detected becoming smaller than the threshold value, the comparator transmits a signal showing the change in the inner pressure to a plate end discriminating part. The plate end discriminating part, receiving the signal showing the change in the inner pressure, decides that the nozzle of the laser cutting torch 1 has reached the end of the plate 7.

Title: Double grating type spectroscopic apparatus
Inventor: SONOBE YOJI
IPC: G01J3/06
Filed: 1988-08-29
Abstract: PURPOSE:To enhance the measuring accuracy of spectral characteristics by respectively detecting the center wavelengths of the lights emitted from the first and second dispersion type spectroscopic elements by utilizing an interference phenomenon of etalon. CONSTITUTION:The center wavelength lambda of the light spectrally diffracted in the first optical system containing a diffraction lattice is detected using reference light and etalon 41 while the center wavelength lambda of the light spectrally diffracted in the second optical system containing a diffraction lattice 30 is detected using reference light (e) and etalon 43. Since the revolving angle between the diffraction lattices 25, 30 is corrected so that the respective center wavelengths lambda are simultaneously detected by the first and second optical systems, the center wavelengths lambda of the lights spectrally diffracted outputted from the diffraction lattices 25, 30 can be allowed to coincide with each other. Therefore, even when the shift of the optical axis of the first optical system containing the diffraction lattice 25 does not coincide with that of the optical axis of the second optical system containing the diffraction lattice 30, the generation of the shift between the center wavelengths lambda of spectrally diffracted lights can be prevented.
