Title: Nonvolatile semiconductor storage device
Inventor: KODA KENJI
IPC: H01L29/78
Filed: 1988-02-19
Abstract: PURPOSE:To produce a large capacity EPROM wherein one memory transistor stores four-value data by a method wherein electric fields generated respectively near a first floating gate and a second floating gate are designed to differ from each other in intensity. CONSTITUTION:Floating gates 6d and 6s are installed through dielectric isolation. On the main surface of a semiconductor substrate 1 near the first floating gate 6d and on either a first regions 2 or 9, regions are provided, different in impurity concentration from an opposite region 3 positioned near the second floating gate 6s. Accordingly, four different combinations of control gate voltages and drain currents are possible: first, a case where electrons are injected into the first floating gate 6d only; second, a case where electrons are injected into the second floating gate 6s only; third, a case where electrons are injected into the first and second floating gates 6d and 6s; and fourth, a case where no electrons are injected at all. This design results in a memory transistor capable of memorizing four values.

Title: Device and method for informing emergency
Inventor: NOJIMA AKIHIKO
IPC: H04W4/90
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To easily perform emergency information without increasing the processing load in a mobile object. SOLUTION: The latitude and longitude outputted from a GPS are stored as history of read latitude and longitude during a normal processing (104, 106) when this emergency informing device is not at an emergency state (100, 102). In the case of operation of an air bag device or depression of a single-touch easy calling key, raw satellite data are requested to the GPS (110) as the emergency state (Y in 100 or 102) and as an emergency information mode (108), and communicating operations of other equipment are prohibited (112). When data reception from the GPS is completed (Y in 114), the history of latitude and longitude is read (116), emergency information is generated by using the raw satellite data and the history of latitude and longitude (118) and is transmitted to a center (120).

Abstract: PURPOSE:To establish the heat treatment method of a sample without the effect of foreign matters in the sample on an immunoassay system, by heating the sample under the specified conditions which are set for an individual antigen or antibody to be measured. CONSTITUTION:An antigen or an antibody is bonded to a film. A marker is incorporated in a microcapsule. The microcapsule, a material which induces dissolution of the film by the reaction of the antigen and the antibody and a sample having an antibody or an antigen that yields the antigen/antibody reaction with said antigen or antibody are mixed. Markers in the microcapsule that are yielded by the destruction of the microcapsule as a result of the dissolution of the film by the antigen/antibody reaction are detected. Thus, the amount of the antibody or antigen in the sample is measured. The sample is heated under the specified conditions which are set for the individual antigen or antibody to be measured so that foreign matters do not affect on a material that induces the dissolution of the film. When the property of the antigen or the value of the antibody is changed in order to suppress the effect of the foreign matters sufficiently, any of the conditions is sacrificed and the adequate conditions are set by compromise.

Title: Projection type cathode ray tube
Inventor: KOUNO SEIICHI
IPC: H01J29/00
Filed: 1979-03-31
Abstract: PURPOSE:To prevent reduction in luminous efficiency and disturbance of color balance by releasing the heat of a target to the outside through a heat pipe. CONSTITUTION:When the target 8 is heated to a high temperature, the heat is transmitted to the heat receiving portion 16 through the face plate 1 to raise the temperature of the heat receiving portion 16, and then transmitted to the radiating portion 17 through the heat pipe 18 connected thermally with the heat receiving portion 16. Since the radiating portion 17 is fixed at the peripheral surface of the face plate 1, its heat radiability can be raised without adding any limitations to its shape and size, and also since the heat receiving portion 16 can be formed to a dimension similar to or smaller than the target 8, the lowering of luminance can be prevented without shielding the image projected from the face plate 1.
