Title: Manufacture of dielectric isolation substrate
Inventor: SATOU AKINOBU
IPC: H01L21/31
Filed: 1985-02-13
Abstract: PURPOSE:To produce a dielectric isolation substrate with specified characteristics while eliminating the causes of leak current by a method wherein a semiconductor region is formed of single crystal silicon encircled by insulating layer. CONSTITUTION:A nitride silicon mask 12 is formed exposing the parts to be formed into letter V type grooves while leaving the surface (100) of N-type single crystal layer 11 as it is by means of utilizing a signal crystal silicon substrate epitaxially grown out of the N-type single crystal layer 11 on the surface of a P-type single crystal silicon substrate 10. When immersed in etchant, letter V type grooves 13 are formed on the surface (100) due to the anisotropy of crystal face during etching process. Firstly P-type polycrystalline silicon 14 is deposited up to the surface of mask 12. Secondly the surface of substrate 11 is ground to expose the nitride mask 12. When the surface is anodized in hydrogen fluoride solution, the P-type polycrystalline silicon 14 is changed into a porous silicon 15. Finally when the porous silicon 15 is processed in oxidizing atmosphere, it may be oxidized into silicon dioxide 16 to be a dielectric isolatin region.

Title: Electrophotographic system printer
Inventor: IKEDA SHINOBU
IPC: B41J2/385
Filed: 1987-02-05
Abstract: PURPOSE:To simplify the maintenance of a printer by placing an electrode on the reverse side of a printing form, and applying directly an electrostatic field to a magnetic brush of a toner by placing the form between the magnetic brush and the electrode. CONSTITUTION:Instead of forming a latent image by executing an exposure to a photosensitive body, an electrode is placed directly on the reverse side of a form and an electrostatic field is generated between a magnetic brush of a toner and the electrode, and the toner is allowed to stick directly to the form. Subsequently, the electrostatic field is continued to match a movement of the form so that the sticking toner does not get out of shape, and it is fixed by the same fixing process as a conventional transfer system. At the time of printing, it is not allowed to pass through a photosensitive drum, therefore, running of the form can be made intermittent freely on the way, and also, by providing magnetic brushes of toners of four colors of black, cyan, magenta and yellow, this printer can be converted easily to a color printer.

Abstract: PURPOSE:To detect the abrasion of gears easily, by holding one gear restrained and rotating the other gear in one direction until said gear is stopped by the restrained gear then measuring the number of revolutions while rotating said gear in the opposite direction and comparing the same with a set value. CONSTITUTION:An auxiliary brake 10 is energized by the command of a main control circuit 11, by which a drum 1 is restrained. When an auxiliary motor 7 is run foward, the drum 1 is held restrained and a gear 4d cannot rotate; therefore, the motor 7 stops as well after rotating to a certain extent. The motor 7 is then run reverse, and the outputs of an encorder 8 by the revolutions of the gears 4a, 4b are read. When the gears 4b, 4c begin to rotate further, the encoder 8 is changed over to an encorder 9. The backlashes among the gears 4a- 4c are measured from the outputs of the encoders 8, 9. The measured values are compared with the set values of a setter 15 in an subtractor 14, and when  the measured values exceed the set value, a lamp of a display device 15 is lighted. The abrasion of the gears 4a-4c is thus detected easily.
