Title: Optical branch structure
Inventor: KOBATA NOBUO
IPC: G02B6/28
Filed: 1983-05-18
Abstract: PURPOSE:To prevent a part of incident light from being reflected unnecessarily and entering an optical fiber for projection as a noise by slanting the tapered end surface of an optical distributor at some angle to a surface perpendicular to the axial direction. CONSTITUTION:When light Pin is made incident to an optical fiber 8 for light incidence, it is considered to be light which passes through a boundary clad 10b directly from the fiber 8 and reflected by an end surface 10a to enter the optical fiber 9 for projection like Pa and light entering the fiber 9 like light Pb. The end surface 10a is slanted, so the light Pa is reflected by the end surface 10a, but the majority of it is made incident to the optical fiber 8 again; and the light Pa is reflected by the end surface 10a and its major part leaks out of a tepered part 10. Therefore, light PISO which enters the optical fiber 9 as a noise with regard to the light Pin is reduced extremely. The isolation of an optical distributor 7 decreases extremely.

Title: Lithium ion secondary battery
Inventor: KAWAMOTO KOJI
IPC: H01M4/133
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery inhibiting lowering of capacity caused by irreversible capacity. SOLUTION: A lithium containing material is mixed in a carbon material composing a negative electrode, and lithium ions uninvolved with the initial charging are held in the negative electrode in advance. When the battery is charged in this state, the lithium ions accepted to the negative electrode from the positive electrode can be absolutely discharged because of existence of the lithium ions added in advance, even though the ions are fixed to the negative electrode as irreversible capacity when discharged. Also after the second cycle of the charging, the lithium ions are moved between the positive electrode and the negative electrode, with the lithium ions fixed to the negative electrode as the irreversible capacity being made up with the lithium ions added to the negative electrode in advance. Consequently, lowering of effective capacity of the lithium ion secondary battery can be inhibited.

Abstract: PURPOSE:To acquire a semiconductor device excellent in corrosion resistance, by extending a wiring layer of corrosion resistant conductive material on the first insulation film, and arranging under a pad region of a junction lead electrode and an opening edge of the second insulation film. CONSTITUTION:A doped poly-Si wiring layer 23 is extended on the first SiO2 film 22 of an Si substrate 20 to connect an impurity layer 21 at one end. The  second CVD SiO2 25 is bored at an extension 23b to expose a pad formation region 24. An opening 26a is made at the region 24 after piling a PSG 26. An Al pad 27 is provided to sinter and to connect a junction lead electrode 28. This constitution prevents the extension 23b between the electrode 28 and the wiring 23 from dixsonnecting, even if the opening 26a exposure is invaded by moisture and the pad 27 is corroded. If the pad 27 disappears, the electrode 28 is connected to the extension 23b directly. The corrosion resistance of the wiring 23 conditions a stable connection. The device increases in its reliability.

Filed: 1978-07-19
Abstract: PURPOSE: To increase a read speed and to improve read efficiency by dividing memories stored with microprograms μPG into three regions read out by a common μPG counter.  
     CONSTITUTION: Read-only storage ROS stored with μPG is divided into (a), (b) and (c) and addresses to be outputted are assigned by common μPG counter MPC. Instructions stored in region (b) have flag bit FB and when FB is not zero, the code with FB is branched at the next step while the output from region (c) is regarded as a branch distance address. The content of a MPC is advanced by clock MLK and synchronizing with clock mck of the double speed of the clock, the contents of regions (a) [or (c)] and (b) are read alternately to read buffer register RBR via multiplexer MXP1 under the control of FF1. When the output from region (b) has FB, a branch address distance is set to MPC and the contents of regions (c) [or (a)] and (b) are read by turn to the RBR, thereby increasing the read speed.

Abstract: PURPOSE:To dope a glass layer with a required and sufficient amount of fluorine, by heating the titled glass layer doped with a metal oxide easily forming glass together with SiO2, and having low evaporation property in a fluoride state in a fluorine-containing atmosphere. CONSTITUTION:For example, a quartz based porous glass layer is manufactured by the vapor-phase axial deposition (VAD) method.

Title: Powder ink
Inventor: SHIMURA EIJI
IPC: B41M5/392
Filed: 1989-04-08
Abstract: PURPOSE:To eliminate the thickness irregularity and surface unevenness of the ink layer of a regenerated ink sheet and to obtain good repeating characteristics by externally adding a conductive powder and an inorg. fine powder to the surface of the matrix particle of powder ink. CONSTITUTION:Powder ink 11 is supplied to an ink sheet 1 in such a state that bias voltage Vb is applied between an electrode 10 and a conductive roller 12 from a power supply 13. The powder ink 11 brought into contact with the release part 8 of the ink layer of an ink sheet receives the injection of charge in the quantity proportional to the product of the electrostatic capacity of an insulating support and Vb because the release part 8 shows insulating properties and is adhered to the insulating support 2 by electrostatic force. However, the adhesion part 9 of the ink layer and the powder ink 11 in contact with the powder ink adhered to the insulating support 2 merely become charge passages because the ink layer and the powder ink are conductive and obtain no adhesive force. Since a conductive powder and an inorg. fine powder are externally added to the matrix particle of the powder ink, the mutual action of the powder ink and the ink layer of the ink sheet can be reduced and the adhesion of the powder ink to the adhesion part of the ink layer of the ink sheet can be eliminated.
