Title: Rotational angle detection device
Inventor: ASAKURA FUMIO
IPC: G01B7/30
Filed: 1994-02-25
Abstract: PURPOSE:To provide sufficient angular output with ease and low cost even in low frequency zone with low revolution by connecting, with a switch circuit, an electric oscillation circuit to a detection coil in a specified frequency zone. CONSTITUTION:When switch points 61 and 62 of a switch circuit 6 are closed, a capacitor (electric oscillation circuit) 5 is connected to a detection coil 32 in parallel, thus a circuit 5 is formed. Meanwhile, a switch control circuit 7, detects the output frequency of a wave form shaping circuit 4, and when it becomes specified frequency area containing the oscillation frequency of the circuit 5, the points 61 and 62 are closed, however they are opened for the area other than that. If the oscillation frequency of the circuit 5 is set to the low frequency area where revolution of a rotation shaft is law and sufficient output is not provided, the circuit 5 comes into oscillation state thanks to the circuit 6 in this area, so sufficient high output is provided from the coil 32. Outside of the frequency area, the circuit 6 disconnects the circuit 5 from the coil 32, so output drop of the coil 32 due to antioscillation is avoided.

Title: Character recognition device
IPC: G06F15/18
Filed: 1992-03-11
Abstract: PURPOSE:To correctly recognize a character and to improve a character recognition rate by synthetically deciding the character type of an input character pattern from the output result of plural character recognition means and group judgement means. CONSTITUTION:The recognized characters are previously sorted into similar character groups 11. It is judged to which group networks GP1-GPn the character pattern 11 inputted in the group judgment network GP belongs. The group networks minutely recognize the character pattern 11 inputted for the respective groups. The output value of the group judgement networks GP and the maximum output value of the respective group networks GP1-GPn are appropriately weighted. All output unit equivalent to the group network of the character group executing optimum recognition finally takes the maximum output value. Then, a synthetic judgement network 12 decides the character of the synthetic maximum output unit as the character type of the inputted character pattern so as to output it.

Title: Arrangement of cells for integrated circuit device
Inventor: TAKAHASHI KAZUHIRO
IPC: G06F17/50
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent the concentration of wirings on a local area and make available such an arrangement of cells which allows an easy achievement of an upper limit value of a delay time after the wiring is done by distributing the cells according to the ratio of the number of virtual wiring grid lines used to the total number of the lines. SOLUTION: In order to divide a substrate 10a, a plurality of cut lines are set in the vertical and the horizontal directions. With the substrate 10a deemed as one cell arrangement region, all the cells 8a-8j in a circuit are distributed in the cell arrangement region constituted of the entire substrate 10a. At that time, care should be taken so that the number of signal lines 9a-9k which cross a cut line 13b may be minimum. At the same time, the ratio of the number of virtual wiring grid lines used to the total number of the lines should be nearly the same in all divided cell arrangement regions. Furthermore, the sum of the areas of the cells distributed to two divided cell arrangement regions should not exceed the total area of cells which can be located in the same divided cell arrangement regions.  By this method, a local wiring concentration wherein wirings are gathered only in one part of the substrate 10a can be prevented.

Title: Circuit for controlling number of burners under energization of boiler
IPC: F23N5/00
Filed: 1992-03-12
Abstract: PURPOSE:To prevent a fuel pressure upon occurrence of abnormal state from being increased by a method wherein a degree of opening setting command for a fuel flow rate control valve is returned back to its previous value when a boiler burner fails to ignite. CONSTITUTION:When a second burner ignition failure 25, for example, is outputted during an igniting operation of a burner in sequence, an output from a NOT circuit 31 becomes 0, AND condition 13 is decayed and an output from a second burner ignition degree of opening command 15 is reset. Then, the burner ignition degree of opening command is returned back to the first burner ignition degree of opening 7 of which condition is already established and a control valve is set to have a degree of opening of the first burner in such a manner that it shows the same flow rate of fuel as that of the ignition of the fist burner. With such an arrangement, the burner ignition pressure is returned back to a proper value corresponding to the number of burners of which ignitions are already completed. In this way, in the case that the n-th burner fails to ignite, it is set to a degree of opening of the (n-1)-th burner so as to prevent an excessive increasing of the fuel pressure.

Title: Information processing device
Inventor: FUKUDA KENJI
IPC: G11B7/005
Filed: 1994-03-24
Abstract: PURPOSE:To suppress the occurrence of data errors as much as possible by constituting a PLL circuit without deviation of a lock point of reproducing data. CONSTITUTION:A phase difference between binarized reproducing data RDT and a synchronizing clock SYNCLK from a VCO 107 is detected by a phase comparator 103. Then, when a duty ratio of a synchronizing clock generated from the PLL circuit 110 deteriorates, the lock point of the reproducing data deviates from the center of a window, so that a jitter margin of the reproducing data deteriorates, and a data error is apt to take place. To prevent the above matter, even when the ratio of the synchronizing clock deteriorates, the lock point of the reproducing data is made to not deviate. For this purpose, a DIS signal outputted from the comparator 103 is outputted by one clock amt. which is independent of the duty ratio, so that fluctuation of pulse width in a CHG and the DIS signal due to the duty deterioration of the synchronizing clock is eliminated, and hence the jitter margin is prevented from deteriorating.
