Title: Character recognition unit
Inventor: KANEMITSU NORIO
IPC: G06K9/46
Filed: 1979-04-13
Abstract: PURPOSE: To improve remarkably the precision of character recognition by making a decision on the kind of a current character to be recognized by referring to the physical relations between the current recognized character and preceding and following recognized characters.  
     CONSTITUTION: A digitized video signal in video memory 7 is supplied to segmenting circuit 8, which generates a quadrilateral circumscribing a character, and its output is stored in memory 12 by way of recognizing circuit 9, character height extracting circuit 10 and character width extracting circuit 11. In memory 12, proposed characters, and character height and character width data are stored being classified by characters to be recognized. Mutual character feature extracting circuit 13 finds the mean value of the character width by the character width data and also finds the mean value of the character height by the character height data to send those mean values to answer editing circuit 14. Assuming that there are proposed charadters, "katakana" (square form of Japanese syllabary ""ro"(Japanese:katakana,256D)" and "handakuten" (make for "p"-sound) "°", circuit 14 selects "katakana "ro"(Japanese:katakana,256D)" when the size of the character is nearly equal to the mean value or "handakuten °" when nearly 1/3 as much as the mean value.

Abstract: PURPOSE:To facilitate handling, to make the output of a sensor constant, and to take an accurate measurement by proving an exciter and a sensor part successively in a casing and allowing the sensor to receive vibrations applied to a body to be measured by the exciter through a point contactor. CONSTITUTION:The exciter 10 has a solenoid 2 and an iron core 3 in the casing 1, a driving case 5 is provided, and the contactor 9 for striking is fitted to the center part of its reverse surface. The case 5 is lowered by a contact pressure spring 7 to make a contactor 9 contact the body 6 to be measured. The sensor part 17 is constituted by supporting a sensor (piezoelectric element) 13 on the edge part of a rubber ring 12 fixed to a support part 11 fitted on the reverse surface of the casing 1 and providing the point contactor 14 to the center part of its reverse surface. The contactor 14 comes into point contact with the body 6 to be measured with a sensor pressing spring 16. When the solenoid 2 is fed with electricity, the iron core 3 moves down to strike the body 6 to be measured through the contactor 9. Consequently, the generated vibration of the body 6 to be measured is received by the sensor 13 through the contactor 14 and transduced into an electric signal. The extent of separation of the body 6 to be measured is detected with the output of the sensor 13.

Abstract: PROBLEM TO BE SOLVED: To unnecessitate carrying of plural prepaid cards by collectively recording the remaining frequency of plural prepaid cards in an electronic wallet. SOLUTION: When a telephone card(TC) 4 is inserted into a TC reading part 202 in an ATM 2, the reading part 202 reads out the balance of the TC 4 and transmits the read balance to a main body control part 201. Then an electronic wallet 1 requiring to store a usable balance left in the TC 4 is inserted into an electronic wallet writing part 203. The writing part 203 transmits the addition of the TC balance transmitted from the control part 201 to a balance stored in a current TC balance storing part to a CPU through the I/O part of the inserted electronic wallet 1. The CPU adds the TC balance transmitted from the writing part 203 to the balance of the TC balance storing part. The TC reading part 20 rewrites the balance of the TC 4 to '0' based on an instruction from the control part 201.

Title: Amplifier circuit
Inventor: KOKETSU TATSUYA
IPC: H03F3/345
Filed: 1990-02-28
Abstract: PURPOSE:To increase the gain without boosting an operating voltage by providing a constant current source injecting a current on an output electrode for which the load resistor of an amplifier element is connected. CONSTITUTION:A constant current MESFET (metal semiconductor field effect transistor) Q6 is provided on the drain of an amplification MESFET Q1 in parallel with a load resistor R1. That is, the gate and source of the constant current MESFET Q6 are connected in common to inject a constant current to the drain of the amplifier MESFET Q1 applying constant current operation. Thus, a resultant current from a current from the load resistor R1 and a current supplied from the constant current MESFET Q6 flows as a drain current of the amplification MESFET Q1. Since the current injection path is provided in such a manner, the current flowing to the load resistor R1 is not amplified but the current flowing to the amplification element is increased to increase the gain without increasing the operating voltage.

Title: Hub
Inventor: SATAKE TEI
IPC: H04L12/413
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the frequency of occurrence of a communication stop state of a terminal equipment or the like due to transmission of a back pressure packet by adding a port selection means that selects a prescribed connection port for transmission of the back pressure packet to the hub provided with a back pressure packet generating means. SOLUTION: A packet received from connection ports P1-Pn of a multi-port repeater 1 and a transmission means 5 is stored once in a buffer RAM 2. A buffer amount detection means 3 reports that data in the buffer RAM 2 reach at least two prescribed amounts set in advance to a back pressure packet(BP) generating means 4 and a port selection means 8. The port selection means 8 sends the BP generated by the BP generating means 4 in the lower priority order decided in advance, e.g. in the order of the connection ports P1, P2,.... Thus, frequency of occurrence of a communication stop state of a plurality of terminals due to transmission of the BP is properly set and a degree of design freedom of the network is enhanced.

IPC: F28G13/00
Filed: 1990-02-28
Abstract: PURPOSE:To prevent corrosion in the subject control of boilers used for thermal power generation, etc. by pouring intermittently into the supply water during operation nomoethanol-amine, diethanol-amine, and triethanol-amine individually or in mixture. CONSTITUTION:A specified amount of one or a mixture of more than two of monoethanol-amine, diethanol-amine, and triethanol-amine is poured into the supply water 3 of a supply water tank 2 or the supply water 3 at the outlet of a supply water pump 5. The supply water to which the above chemical is added is sent to a steam converter 10 through a drain cooler 6, pipe 7, deaerator 8, and pipe 9. At this time the monoethanol amine, etc. that are mixed have a low distribution rate because of their high boiling point and stay in the water 15 of the device. It is, therefore, possible to hold for a long term the pH value of the water in a device 15 at about pH 9.0 - 9.6 and to prevent corrosion for a long time.

Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To control a video conference system intuitionally by controlling video information with a user entry from a pointing device without displaying an icon corresponding to the pointing device. SOLUTION: A display screen 32 is used completely by video information to provide a display 44 of a video image. An icon denoting a position of a pointing device is not given.
