Title: Image formation device
Inventor: OTSUKA KEIZO
IPC: G03G15/02
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent the fog and the deterioration of the thin line reproducibility of an image resulting from the change of a charging bias with the change of temperature of humidity. SOLUTION: A charging bias is applied to a charging roller 2 as a contact charging member by a charging bias power source 3 so as to uniformly charge a photosensitive drum 1 surface at a predetermined potential. The charged potential of the photosensitive drum 1 surface varies by temperature or humidity. A temperature detection means 16 is contacting disposed to a charging roller 2 surface, and a humidity detection means 17 is disposed in the vicinity of the charging roller 2. Based on the detection results, the charging bias power source 3 is controlled by a control means 18, and the charging potential of the photosensitive drum 1 surface is set so as to obtain sufficient development contrast. Thereby, the fog and the deterioration of the thin line reproducibility of an image is prevented.

Title: Dna marker placed closely to rice cytoplasmic male sterility-restoring gene and discrimination of cytoplasmic male sterility-restoring gene by use of the same
Inventor: INAGAKI AKIKO
IPC: C12Q1/68
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To obtain a DNA marker capable of discriminating the gene type of rice cytoplasmic male sterility-restoring gene (Rf-1) at a DNA level, improving the efficiency of rice growth, and controlling the purity of seeds by using a primer having a specific base sequence and placed closely to the rice Rf-1. SOLUTION: This DNA marker has a base sequence of formula I and boards at a place of 1 centimorgan (cM) closely to the rice Rf-1. The method for discriminating the gene type of the Rf-1 comprises preparing a pair of primers for detecting the DNA marker from a primer having the base sequence of formula II and a primer which is faced to the primer and has a continuous 15-40 base length base sequence selected from the 492 to 2371 bases in the base sequence of formula I, and subsequently subjecting a pair of the primers to a PCR using rice DNA as a template. When the DNA fragment originated from the DNA marker is amplified, it is judged that the DNA marker does not have the Rf-1. When the DNA is not amplified, it is judged that the DNA marker has the Rf-1.
