Title: Method for encoding picture element by rapp method, encoder and computer system using the method
Inventor: RATNAKAR VIRESH
IPC: H04N1/41
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To predict a present picture element through the use of the pattern of the picture element in the neighborhood by predicting the label of the picture element based on the comparison of probabilities which are decided for every basic pattern label and encoding the picture element based on a predicted label and an effective label. SOLUTION: When un-encoded picture element is recognized in the raster order arrayal, the extension pattern of the present picture element is decided (S102 and S103). Then, it is predicted that the present picture element is the same as that in the neighborhood, which is provided with the lowest label in a dictionary formula among the labels having a max. predicting probability in the decided extension pattern (S104). Unless the prediction is proved right, it is inspected which picture element other than the predicted in the neighborhood the present picture element is the same (S107). At the time of unsuccess in this test the value of the present picture element is added to an Anomaly List and, moreover, a symbol ANOMALY/-n is added to a Trend List (S109 and S110).  Then, the prediction probability of the present extension pattern is updated based on the effective value of the present picture element (S111).

Title: Linear step motor
Inventor: KAWAMURA KAZUJI
IPC: H02K41/03
Filed: 1990-01-26
Abstract: PURPOSE:To maintain constant the overall magnetic resistance of a closed magnetic path, established through a mover or a position detector secured to the mover, by differentiating the ratio of the crest and root at the joint of a stator with respect to a stator tooth from those at other parts thereby differentiating the cross sectional area at the joint from those in other parts. CONSTITUTION:Cross sectional area at the joint 10 at the crest of a stator 1, for example, is set larger than the cross sectional area at other crests. The ratio between the crest and the root of the stator 1 is set such that the increase of magnetic resistance in a closed magnetic path, established by a mover 3 or a position detector 8 secured to the mover 3, due to increase of air gap magnetic resistance at a joint 10, when the closed magnetic path passes through the joint 10 of the stator 1, is offset by the decrease of magnetic resistance at the core part due to the difference of crest/root ratio of the stator tooth 2.

Title: Automatic threshold level controlling circuit
Inventor: KURIYAMA NOBUMI
IPC: H03K5/08
Filed: 1980-02-16
Abstract: PURPOSE:To set the threshold level at the optimum value and at the same time discriminate the no-signal, by using the mean value between the maximum and minimum values of the input signal for the comparing threshold level of the input signal and also installing a control circuit for the threshold level. CONSTITUTION:The input signal is applied to the input terminal of 23 of the comparator 22 as well as to the maximum and minimum value detector circuits 25 and 26 each. Thus the maximum and minimum values are detected for the input signal. The mean value detector circuit 27 averages both the supplied maximum and minimum values of the input signal to obtain the reference voltage of the circuit 22. Thus the threshold level has a fluctuation by the same value although the amplitude of the input signal has a fluctuation and the DC level of the input signal has a fluctuation. In this connection, the threshold level is always set at 1/2 the input amplitude. As a result, the fluctuation of pulse duration can be prevented for the output pulse. Furthermore, the threshold level limiting circuit 28 works while no input is given, and thus the threshold level is prevented from lowering down to zero level. Thus the no-signal can be discriminated. In other words, a discrimination is possible for the (n) DC signal.

Abstract: PURPOSE:To control remote-side subscribers of the same communication for transmission/reception with the same address, by using a communication controller to control the information which decides the address of a message within a network and the information which is delivered to a terminal at the receiver side after discriminating both information from each other. CONSTITUTION:When a message is sent to a communication terminal device B2 from a communication terminal device A1, the address information 5a given from a device 1 is supplied to an address area 7a at a transmission destination via a communication controller CA3. While a message 6a is sent to a message area 7c, and a transmitter address is set at a transmitter addreass area 7b. Thus a packet 7 is formed. This packet 7 is delivered to a communication controller CB4. The CB4 produces the address information 5b and a message 6b through areas 7b and 7c respectively and sends them to a communication terminal device 2. Then a packet 10 is produced in an adverse process when a message is sent to the device 1 from the device 2. In this case, the transmission address information 5a of the reception address information 8b of the device 1 are coincident with each other with an address of the device 2 owing to the conversion of address information done by controller CA3 and CB4.

Title: Turbo-compressor system for fuel cell power generation
Inventor: MITANI HISASHI
IPC: H01M8/06
Filed: 1984-01-30
Abstract: PURPOSE:To make it possible to control a flow rate for air supply to a compressor over a wide range without causing any trouble, such as surging, by providing a by-pass line, which connects the outlet of a compressor to the inlet of a turbine, with a flow rate regulating valve which is to be opened in the operation range where the amount of air to be supplied to a fuel cell and a modifier is limited. CONSTITUTION:With the extra air from the outlet of the air electrode of a fuel cell 1 and the exhaust gas of a modifier 2, a turbine 14 operates to drive a compressor 12. Consequently the air flowing through an air feed line 15 is compressed up to the required level and is fed to an air chamber 8 of the fuel cell 1 and the modifier 2 successively for power generation. However, when the operating condition of the compressor 12 comes in the area A where surging takes place, a flow rate regulating valve 18 is opened to the desired degree. As the result, part of the air discharged from the compressor 12 is led to the turbine via by-pass line 17, and therefore the air flow rate passing through the compressor 12 increases and the operating condition of the compressor 12 is returned to the regular operation area B on the right side of a surge line 1, thus preventing effectively the generation of surging.
