IPC: G03G9/113
Filed: 1989-04-14
Abstract: PURPOSE:To maintain a stable image density and triboelectrostatic charge quantity even in the case of copying many sheets at and under a high temp. and high humidity and to obtain stable copies free from scumming in the non- image parts by incorporating magnetic powder, polyester resin having <=5 mgKOH/g acid value and <=25mgKOH/g hydroxyl value, and specific metal- contg. monoazo dye into the carrier. CONSTITUTION:This carrier contains the magnetic powder, the polyester resin having <=5mgKOH/g acid value and <=25mgKOH/g hydroxyl value and the metal-contg. monoazo dye expressed by formula I. Ferromagnetic powders, for example, powders, such as gamma-Fe2O3, Fe3O4, iron powder, Co-contg. gamma-Fe2O3, and ferrite, are used as the magnetic powder. A small amt. of polar group-contg. polyolefin may be added to the carrier in order to enhance the uniform dispersibility of the magnetic powder.

Title: Manufacture of semiconductor device
Inventor: AKIYAMA SHIGENOBU
IPC: H01L21/265
Filed: 1979-07-20
Abstract: PURPOSE:To obtain a solar battery having excellent characteristics without using expensive complete crystal by implanting reverse conductivity ion onto one main surface of one conductivity type semiconductor substrate excluding one end of the substrate and heat treating it in O2 or Ar containing HCl. CONSTITUTION:N-type impurity ions are implanted onto a P-type Si substrate to form an N-type layer having uniformly controlled surface density in a depth of 0.2-0.3mum. After heat treatment, this implanted layer does not produce irregular distribution of crystal defects nor deposit impurity in the vicinity of the junction surface. In order to reduce the leakage current at the end face of the formed P-N junction, the end of the surface of the substrate is etched after forming an elecrtode, or the end of the substrate is coated with a mask before implating the ions to prevent formation of an N-type layer at the end of the substrate to thus reduce the reverse leakage current at the P-N junction. After the implantation, it is heat treated in O2 or Ar containing HCl to form a P-N junction. This configuration can obtain excellent characteristics by using inexpensive ribbon crystal and polycrystals in the device.

IPC: H04M19/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a telephone system which can effectively reduce power consumption not only at a computer terminal but also in a system as a whole by interrupting power feeding to a telephone set coordinated to a computer terminal when an operation condition of the computer terminal transits from a normal mode to a standby mode. SOLUTION: When each of computer terminals 4A to 4N transits to operation waiting state by a user, that is, a standby mode in accordance with activation of screen saver, a power saving operation or the like, a management part 22 of a server 2 is informed of change in this operation mode. Then, when operation conditions of the computer terminals 4A to 4N enter in the standby mode, it is decided that the user is absent and power feeding to button telephone sets 3A to 3N coordinated to the computer terminals 4A to 4N is interrupted. Therefore, even if the user is absent, power consumption can be reduced not only at the computer terminals 4A to 4N but in a whole system in comparison to a case in which normal power feeding is performed from a main device 4.
