Title: Image reader
Inventor: HASHIMOTO SHOZO
IPC: G06T1/00
Filed: 1989-04-14
Abstract: PURPOSE:To prevent the danger caused by continuously lighting a light source by executing an operation after an image reading means and an image data processing means mutually detect a fact that they can operate, respectively. CONSTITUTION:This image reader is constituted so that a light source 1 is lighted only when both an image reading means 20 and an image data processing means 18 can operate. In such a way, even if an image scanner in which the image reading means 20 exists becomes an abnormal state, the light source 1 is not lighted and a dangerous state can be prevented. Also, when a memory 13 which the image data processing means 18 has becomes full and exceeds the read range, the light source 1 can be turned off, and accordingly, an operator can decide a stop of the operation.

IPC: G03B42/02
Filed: 1989-04-14
Abstract: PURPOSE:To accurately perform processing based upon irradiation field recognition by finding an irradiation field area ratio indirectly and comparing it with an irradiation field area ratio calculated from a recognized irradiation field. CONSTITUTION:The area ratio Q of the recognized irradiation field to the entire recording area of a recording medium is found, the signal minimum value Smin of the histogram of an image signal and an upper limit value betanearby the maximum value Smax which is found from it area found, and a signal value Sm which has a specific cumulative frequency close to 50% in the cumulative histogram in the range between the Smin and beta is found. Then while R0 is regarded as a specific set value, a signal value alpha which satisfies R0=(Sm-alpha)/(beta-alpha) is found and the ratio Q0 of the frequency of the image signal in the range alpha-Smax to the frequency of the whole image signal is found. When the difference between the ratio Q0 and area ratio Q is less than a specific value, it is decided that the recognized irradiation field is correct, but when not, it is decided that the recognized irradiation field is wrong.

Title: Conductive paste
Inventor: KAWAMINAMI SHUICHI
IPC: H01B1/22
Filed: 1989-04-17
Abstract: PURPOSE:To improve the solder wettability of a conductor by adding Cr2O3 to Ag-Pd paste.

Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain such a state that there is no attachment of organic matters for a silicon insulating film without changing the characteristics of the silicon insulating film, by heat-treating the silicon insulating film in an oxydizing atmosphere of such a temperature that does not increase the thickness of the silicon insulating film. SOLUTION: On a surface-washed silicon semiconductor substrate 10, a silicon oxide film 12 which will serve for a gate insulating film is formed by pyrogenic method. The atmosphere of a thermal oxidation furnace is kept in an inert gas atmosphere until the temperature of the silicon semiconductor substrate 10 becomes the room temperature. The atmosphere of a reaction furnace into which a boat mounted with the silicon semiconductor substrate 10 is to be carried in is set to such a one that the volume ratio of nitrogen gas to oxygen gas is 9:1. Then, the atmospheric temperature of the reaction furnace is increased to 450 deg.C at the rate of, for example, 10 deg.C/min. After that, this oxidizing atmosphere and temperature is kept at it is for 10 minutes, during which the silicon oxide film 12 is heat-treated to burn and remove organic matters attaching to the surface of the film 12, resulting in almost no change in the thickness of the silicon oxide film.

IPC: G09B23/18
Filed: 1988-04-19
Abstract: PURPOSE:To facilitate the handling and to grasp a magnetic field distribution in three dimensional by confining magnetic powder in a container and arraying respective particles in three dimensions. CONSTITUTION:An enclosed transparent container 1 is formed of a magnetically permeable synthetic resin material or glass material and filled with a viscous liquid 2, with which the magnetic powder 3 is mixed. When magnetic poles 5 and 6 of a permanent magnet 6 or electromagnet are applied to the external surface of this container at proper positions, the magnetic powder 3 in the container moves in the liquid 2 and gathers in the magnetic field of the permanent magnet 4. Respectively particles of the magnetic powder 3 are magnetized in this magnetic field, but the respective magnetized particles are linked in a suspended state along the flow of lines of magnetic force because they are in the viscous liquid 2. Consequently, the distribution state of the magnetic field in the transparent container is represented in three dimensions and easily observed from the outside of the container.

Title: Method for information processing using neural network
Inventor: YOSHIKAWA SHINJI
IPC: G06F15/18
Filed: 1995-04-21
Abstract: PURPOSE: To find the differential coefficient of a network accurately in a short time in addition to the output value. CONSTITUTION: In addition to a neutral network having nodes denoted as (n), a 2nd network having nodes represented as N is provided together. The 2nd network receives the output values of nodes of 1st and succeeding layers of the neural network and performs four arithmetical roul operations. The four arithmetic roul operation expression uses the derivative of a sigmoid function being the operational expression of the neural network. The 2nd network employs (a)-(f) among connection coefficients of the neural network as coefficients. The derivative of the sigmoid function is represented as the polynomial of the sigmoid function itself, so the 2nd network gives the differential coefficient of the output value of the 1st network.  At this time, no approximation technique is used, so the precision is high, and only the four arithmetic roul operations are performed, so the load of the calculation is also light.

Abstract: PURPOSE: To estimate an activated state of a catalyst with high accuracy by sensing an intake amount of an engine, and computing an integration value of heat quantity supplied to the catalyst based on the sensed intake amount. CONSTITUTION: In a control unit 12, a cooling water temperature Tw of an engine 1 is sensed by a water temperature sensor 15, and a reference quantity of heat Cϕ is set while corresponding the initial cooling water temperature Tw to an initial temperature of the catalyst 10. When the reference quantity of heat Cϕ is not zero, the catalyst is determined not to be activated. Warming-up control is started for early activation of the catalyst. When the engine 1 is not in a fuel cut state nor an idling state, quantity of heat A supplied to the catalyst 10 from exhaust is estimated and computed based on the intake air amount Q which is sensed by an air flow meter 13. The calculated quantity of heat A is added to the former integration value CHn-1 to obtain the present integration value CHn . When the quantity of heat integration value CHn exceeds the reference quantity of heat Cϕ, the catalyst 10 is determined to be activated, and warming-up control is completed.
