Title: Cr-al coating method
Inventor: CHIKAZAKI MITSUO
IPC: C23C10/02
Filed: 1980-02-08
Abstract: PURPOSE:To improve the resistance to thermal shock of a composite coating layer, by coating heat resisting alloy with Cr, then by coating said alloy with a mixed powder comprising Al powder, an activator for halogenation, alumina powder, and B powder etc. in order to perform Al coating. CONSTITUTION:Heat resisting alloy is first coated with Cr. Then said Cr-coated heat resisting alloy is buried in a mixed powder consisting of Al powder, an activator for halogenation, alumina powder, and B powder or boron halogenide powder in a quantity 0.01-5wt% of Al, and is heated in a nonoxidizing atmosphere in order to perform Al coating. Hereby, a composite Cr-Al layer excellent in resistance to thermal shock and corrosion is formed. Preliminary coating of the heat resisting alloy with Ni prior to said Cr coating allows to improve further the resistance to thermal shock.

Abstract: PURPOSE:To simultaneously measure the direction and quantity of birefringence by providing a mechanism for rotating a transparent medium to be measured in accordance with the quantity of light receiving through a polarized light splitting means. CONSTITUTION:The linear polarized light emitted from a laser 11 is passed through the surface layer 13 of an optical card 12 as the transparent medium injected into the card 12 fixed to an optical card mount 14 and reflected. The polarization characteristic is changed in accordance with the birefringence quantity of the surface layer 13, and the light is then passed though a polarized beam splitter 15 and splitted into both polarized beams P and B which are received by polarized light detectors 18 and 19. The card 12 is rotated by a stepping motor 17 in accordance with the quantity of the former beam received. The direction of birefringence is measured from the angle of rotation, and the quantities of beams at their maximums received by the detectors 18 and 19 are then inputted to a computer 20 to calculate the birefringence quantity.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/01
Filed: 1988-01-27
Abstract: PURPOSE:To prevent deterioration in image quality by providing a means AC- discharging to a photosensitive body, and a means uniformly projecting light of wavelength transmitting toner on the photosensitive body almost at the same time as discharging, after a developing step and before a transfer step. CONSTITUTION:A discharge/exposer 10 is provided between developing units 4A-4D and a transfer electrode 5. When an electrification electrode 12 for the discharger/exposer 10 discharges AC coronas eccentrically electrified to polarity identical to a background potential (negative), the uniformity of the surface potential of the photosensitive body is improved with positive and negative corona ions to lower the potential of the background. In a negative toner adhering part, opposite charges (positive) on the base side move toward the photosensitive body to prevent toner scattering. In case of electric charges beneath a toner overlapping area, the photosensitive body below the toner adhering part is exposed when wavelength transmitting the toner is employed for light from a light source 14. Thus, toner scattering is minimized to prevent deterioration in image quality.

Title: Method of kneading ceramic material
Inventor: NIIHATA OSAMU
IPC: B28C3/00
Filed: 1993-02-02
Abstract: PURPOSE:To prevent lowering of quality due to the contamination of dried attachments by performing high speed rotation through placement of only aggregates after discharging kneaded matter, and then performing intermediate speed rotation for kneading with the addition of a molding assistant and a baking assistant after scraping previous kneaded matter attached to the side surface of the vessel. CONSTITUTION:At first, a particulate matter of sludge-molten slab is put into a dispersion-mixing type mixer where kneaded matter is discharged, and then it is permitted to run idle at high speed. As a consequence, the aggregate slab is dispersed heavily within the mixer so that dried attachments on the mixer wall surface are removed therefrom. Subsequently, a molding assistant is added, to then be kneaded at intermediate speed, and further a baking assistant is applied and then kneaded to be made into a ceramic material. By taking this method, water cleaning for the attachments is not necessitated, a ceramic material can be kneaded abundantly continuously, and drop of quality is prevented by avoiding the entry of attachments.
