IPC: H04Q9/00
Filed: 1993-11-04
Abstract: PURPOSE:To lessen the number of times of processing on reception side and reduce the burden on reception side by staggering the time to send out the same information to a plurality of circuits and quitting the transmission to other circuits on reception side in case that the transmission is normally finished within the time difference. CONSTITUTION:When transmitting the same information via a plurality of transmission circuits 403 and 404, priority circuit managing means 101 and 201 manage which circuit to use preferentially. And, in case that it receives a reception answer within a specified time after transmitting information with a priority circuit once, it does not transmit the same information via other transmission line. Moreover, only in case that there is no reception answer within specified time after transmitting the information with the same prior circuit once, it transmits the same information, placing a time difference via other transmission circuit. Hereby, the burden of processing on reception side can be lessened.

Filed: 1990-10-15
Abstract: PURPOSE:To prevent the spectral characteristics of the color filter from deterioration owing to the coloration of a colored layer by heating a fat in an atmosphere incorporating no oxygen when a film is formed by a curing process with the heating. CONSTITUTION:When the colored layer 6 is formed by coating a substrate 2 with photosensitive resin 4 incorporating pigment, the curing process by the heating of the colored layer 6 is carried out in vacuum where no oxygen is present, or in nitrogen or inert gas. Namely, a heat plate 9 which is set at specific temperature by a temperature controller 8 is provided in a heat treating device 7 and the color filter 1 is mounted on the heat plate to cure picture elements. After the heat treating device is evacuated sufficiently by a vacuum pump 10, nitrogen is admitted to the heat treating device through a nitrogen intake 11 and while an exhaust port 12 is opened to discharge the nitrogen and gas produced at the time of the curing, a heat treatment is carried out for a specific time. Consequently, the colored layer is prevented from deterioration in the spectral characteristics owing to the color change of the photosensitive resin into yellow during the heating and the color filter which has the superior spectral characteristics is obtained.

Title: Hybrid integrated circuit
Inventor: SHIMIZU AKIRA
IPC: H05K1/16
Filed: 1990-10-17
Abstract: PURPOSE:To obtain a high-density hybrid integrated circuit through realization of a thick-film resistor of relatively small dimension and large trimming ratio for maximum to minimum resistance value by designing the title circuit so as to have a thick-film resistor having two or more regions gradually thicker in the breadth direction and connected to conductors at both ends in the longitudinal direction. CONSTITUTION:This circuit is so designed as to have a thick-film resistor (a) having two or more regions a1, a2 gradually thicker in the breadth W direction and connected to conductors b1, b2 at both ends in the length L direction. For example, the resistor (a) has a breadth W and a thick region a1 w1 wide and a thin region a2 w2 wide with two conductors b1, b2 connected to both ends and the trimming is made along a track (c) starting from the thick region a1. This design causes gradient to be gradually sharper up to the end w1 of the thick region a1 by showing a similar variation in resistance value as that of a normal resistor, and then to be smooth again upon entrance from w1 into the thin region a2; therefore, even in a maximum trimmed state Max, functional trimming can be made exactly.

Patent JP-H03138807-A (JP)
Title: Conductor paste
Inventor: MATSUYAMA SHIROHITO
IPC: C09D11/52
Filed: 1989-10-24
Abstract: PURPOSE:To obtain multi-layer wiring substrate having high reliability without a cavity by adding specific liquid hydrocarbon system oil to the paste composed of metal powder and a vehicle. CONSTITUTION:W powder having a mean grain diameter of 1mum and ethyl cellulose previously melted in terpineol are blended to make a paste with a viscosity of 2,000 poise by the three rollers. A fine line of 200mum width is screen- printed with hydrocarbon oil, having the number of (n) of 13 or more in CnH2n+2, added to the paste. In this case, oil addition quantity is made 1-6% to the paste 100wt.%. This is because a cavity-decreasing effect is not appreciable if it is less than 1%, and a sharp fine line is not obtainable if it is more than 6% due to the bleeding of oil. This prevents the occurrence of a cavity of a fine pattern when paste is printed and dried, and a multi-layer wiring substrate having high reliability can be obtained.

Filed: 1988-10-31
Abstract: PURPOSE:To extend a detection range of the amount of electric charges by providing an impurity region under a charge output gate electrode and electrically connecting a floating diffusion layer. CONSTITUTION:A p type impurity region 4 is provided under the surface of a p type semiconductor substrate 1 adjoining to an N type floating diffusion layer 3S, and a charge output gate G0 is electrically connected to a voltage output gate G. Here are stored in a potential well under a first gate G1 electric charges Q transferred from the left with phi1 clock application voltage H and phi2 clock application voltage L. The N type floating diffusion layer 3S is fixed to a potential V1 and becomes a potential V1a just under the gate G0. Then, phi1, phi2 clock application voltages are reversed to bring the phi1 clock application voltage to L and the phi2 clock voltage to H. Hereby, the electric charges Q stored in the potential well just under the phi1 clock flow into the N type floating diffusion layer 3S becomes greater than prior arts.

Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To perform more certain individual authentication by improving referencing precision. SOLUTION: For data registration, respective 1st electrodes of six sensor element arrays A to F are selected and supplied with a carrier signal selectively in order. Carrier signals having passed through a finger from 2nd electrodes are received in order, and the received data are rearranged to obtain respective sensor element array data. The sensor element array data which is the easiest to reference is selected out of those sensor element array data and saved as referencing dictionary data in a memory. For data reference, carrier signals having passed through the finger from the 2nd electrodes are similarly received in order and rearranged to obtain respective sensor element array data. Those sensor element array data are compared with and referenced against the previously registered dictionary data.  Then the person is identified when there is one or more piece of array data whose similarity to the dictionary data is larger than set similarity.

Title: Drive control circuit for electromagnetic pump
Inventor: MORITO KATSUMI
IPC: F23N1/00
Filed: 1994-11-10
Abstract: PURPOSE: To dispense with the constant voltage circuit of an electromagnetic pump used in the fuel pump for various burners and to perform control of a pump flow rate to a constantly proper value. CONSTITUTION: An output voltage VD from a constant voltage circuit is exerted on the exciting coil L1 of an electromagnetic pump MP through a current control element Q1. The terminal voltage VDET of a current detecting resistor R0 is exerted on a current control circuit Q3. A current control circuit Q3 outputs a control signal, by means of which an exciting current amount exciting current IA is controlled according to the intensity of the terminal voltage VDET of the current detecting resistor R0, and a current control element Q1 controls a current amount IA fed to the exciting coil L1. In this case, since a current control signal is a value responding to unevenness inherent to the exciting coil L1 and a mechanical loss, there is no need for microcontrol, and a pump flow rate of an electromagnetic pump MP being an object to be controlled is directly controlled to a proper value.

At such a time, if the number of copies calculated from the maximum number of containable discharged sheets of the bin 16 and the inputted number of sheets of the original is smaller than the inputted number of copies, the number of copies obtained is set to the limited number of copies that can be copied by preengaging.
