Title: Y/c separator
Inventor: HATANO TAKAHISA
IPC: H04N9/78
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent dot interference from getting conspicuous even when correlation is erroneously detected by applying a horizontal BPF when the high frequency level of an input signal is low concerning adaptive Y/C separation for separating a compound color TV signal into a luminance signal and a chrominance signal. SOLUTION: When a noticed signal is a black level and a line to form a comb filter is the chrominance signal, the dot interference at the 1/2 level of chrominance signal component of the line to form the comb filter appears in the noticed signal. At such a time, when a source signal is black, the dot interference is made conspicuous in comparison with the case the source signal is not black. Therefore, when the noticed signal is the black level, a BPF application circuit 13 decides the selection of a BPF 5. Besides, it is similar even when the noticed signal is the chrominance signal and the line to form the comb filter is the black level. Further, it is also similar in the case of white level having no chrominance signal.  Concerning this circuit 13, the result of detecting the high frequency level for one cycle of sub-carrier in horizontal direction, for example, is smoothed and the dot interference is prevented from getting conspicuous.

IPC: C23C12/00
Filed: 1989-02-08
Abstract: PURPOSE:To provide the structure of the surface part of driving system parts without causing troubles such as pitting and peeling, etc., on the surface even if the parts are used under severe conditions by subjecting the surface layer part of the driving system parts to a carburization hardening treatment to form the diffused layer of C atoms and forming the diffused layer of a carbide forming element on the surface layer part of the above-mentioned diffused layer. CONSTITUTION:The diffused layer 3 of the C atoms is formed on the surface layer part of the driving system parts 1 and the diffused layer 4 of the carbide forming element is formed on the surface side of the diffused layer 3. Since the diffused layer 4 has extremely high hardness, the sufficiently high hardness is assured on the surface of the parts 1. The surface layer part of the parts 1 is the diffused layer 3 of the C atoms and the surface layer side of the diffused layer 3 is the diffused layer 4 of the carbide forming element. The layers are, therefore, shifted successively from the surface of the parts 1 having the higher hardness to the diffused layer 4, the diffused layer 3 and a base material 2 which are successively lower in hardness. Namely, the hardness grade under the surface of the parts 1 changes gradually. The sufficient toughness is, therefore, assured on the surface of the parts 1.

Title: Measurement of toner concentration
Inventor: UTAKA TOMIMASA
IPC: G03G15/08
Filed: 1989-02-09
Abstract: PURPOSE:To obtain an optimum printing density by providing a toner concentration sensor inside an image carrier and measuring the concentration of toner in a developing area between a magnetic roller and the image carrier. CONSTITUTION:A supporting body 28 is fixed on a shaft 27 provided in the central part of a photosensitive body 25. The toner concentration sensor 29 is fitted to the top of the supporting body 28 and detects the concentration of the toner in the developing area 26 in a position facing the developing area 26 inside the photosensitive body 25. Namely, the flow of the toner is low in the developing area 26, and therefore a change in magnetic permeability decreases when a replenishing amount is constant. The concentration of the toner in the developing area can be more precisely detected than in an agitating area. Consequently, the concentration of the toner in the developing area can be measured precisely, and an optimum printing density can be obtained.
