Title: Printer and image recording method
Inventor: SUMIYA SHIGEAKI
IPC: B41J2/205
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a memory for storing the gray level error allocation value in a printer where on/off of a dot is determined by error diffusion method and the gradation is represented by dot distribution. SOLUTION: With regard to an interested pixel, a gray level error allocated from peripheral pixels is added to an input data to determine a corrected data CorD(x) (Step S160) It is then compared with a threshold value THL to decide whether a dot is formed for that pixel (Step S170 through S190). A gray level error errT is then determined based on the fact whether a dot is formed or not (Step S200) and allocated to the peripheral pixels while being weighted specifically. In this regard, gray level errors being allocated to adjacent pixels in the subscanning direction are stored not in a new buffer but in a butter for a pixel which has been subjected to error diffusion already. According to the method, capacity of an error diffusion butter can be reduced.

Title: Method for controlling density of adsorbed hydrogen on surface of solid silicon
Inventor: HIROSE FUMIHIKO
IPC: H01L31/04
Filed: 1993-12-14
Abstract: PURPOSE:To enlarge the scope of application of solid silicon treated by coating with hydrogen and control the density of adsorbed hydrogen by irradiating the surface of the solid silicon kept in a vacuum with atomic hydrogen in increasing the density of the adsorbed hydrogen and with electron beams in decreasing the density of the adsorbed hydrogen. CONSTITUTION:This method for controlling the density of adsorbed hydrogen is to irradiate the surface of solid silicon kept in a vacuum with atomic hydrogen in increasing the density of the adsorbed hydrogen on the surface of the solid silicon and with electron beams in decreasing the density of the adsorbed hydrogen on the surface of the solid silicon. The atomic hydrogen used in increasing the amount of coated hydrogen on the surface of the solid silicon has remarkably high chemical reactivity as compared with that of molecular hydrogen and is adsorbable on the surface of the silicon even with an extremely low thermal energy. Thereby, the hydrogen can be adsorbed on the surface of the silicon at a higher rate and a lower temperature than those of conventional hydrogen heat treatment in which the hydrogen unconverted into atoms is adsorbed on the surface of the silicon.
