Title: Pressure atomizing burner
Inventor: NAKAMURA KAZUHARU
IPC: F23N1/00
Filed: 1982-08-07
Abstract: PURPOSE:To stop the fuel outflowing from an atomizing nozzle immediately after combustion stop operation is performed and at the same time improve ignition performance by a structure wherein an oil storage chamber, the volume within which is enlarged when its oil pressure is lowered, is provided in a pipe conduit connecting between a fuel pressurizing pump and an atomizing nozzle. CONSTITUTION:When the fuel pressurizing pump 1 is put into operation, the fuel in the pipe conduit 3 pushes a check valve 4 open and compresses a pressure damper 5, resulting in reducing the volume of the oil storage chamber 7 with a piston 10. When the burner is operated to be put off under the conditions mentioned above, the fuel pressurizing pump 1 comes to a standstill and consequently the damper 5 is returned to its former position by the force of a spring 6 and at the same time the fuel accumulated in the damper 5 is flowed through an orifice to a return pipe 12 because of the check valve 4 arranged. On the other hand, because the spring 6 of the damper drives the piston 10 so as to enlarge the volume of the oil storage chamber 7, the fuel in a high temperature atomizing nozzle 2 and a connecting pipe conduit 3 is received in the oil storage chamber 7. Accordingly, after the stoppage of the pressurizing pump 1, no fuel flows out of the atomizing nozzle 2 and no fuel accumulates in the combustion chamber 1, resulting in improving the combustion efficiency.

IPC: H04W88/02
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To prevent the device from being larger in size and from getting a high cost due to a useless storage section. SOLUTION: The speech recognition operation device (portable telephone set 10) is provided with a single common use storage section 50 that uses in common 1st, 2nd dial number storage sections 38 and a name of one's name pattern storage section 22 and has the variable size and boundary of the respective storage sections. Then the storage section 50 varies the size and the boundary of the respective storage sections so that a storage section used most frequently occupies a widest area and a storage section not frequently used occupies a smaller area depending on the difference in the frequency of use by the automatic dialing system. Thus, the single storage section with a narrower area than the sum of areas of a conventional storage section is enough for the purpose.

Title: Fingerprint detecting method
Inventor: YANAGIMOTO TAKAYUKI
IPC: G06T1/00
Filed: 1987-06-02
Abstract: PURPOSE:To easily detect the fingerprints by radiating the light containing no fluorescent wavelength to a fingerprint detecting object which is pretreated by a treating agent containing a fluorescent coloring matter and cutting the excited light for detection of the fluorescent light only. CONSTITUTION:A fingerprint attached to a specimen 8 is pretreated by a solution containing a fluorescent coloring matter, e.g., Rhodamine G. The light emitted from a lamp light source 5 is made incident on the specimen 8 via a projecting optical system 6 and a short wavelength pass filter 7 which transmits the light of the short wavelength side compared with the fluorescent light of the fluorescent coloring matter. The light radiated from the specimen 8 is transmitted through a long wavelength side pass filter 11 for deletion of the excited light. Thus only the fluorescent light is made incident on a 2-dimensional image pickup device 9 via a light receiving lens 10. Then the obtained video signals are displayed on a picture monitoring device 13.

Title: Monitor for pll circuit
Inventor: UCHIUMI HIROAKI
IPC: H02M7/48
Filed: 1982-08-09
Abstract: PURPOSE:To monitor a signal which is outputted from a PLL circuit without influencing a control system by comparing the counted value of a counter which inputs a signal to be applied to the PLL circuit with the preset upper and lower limit values, thereby stopping a control signal. CONSTITUTION:A frequency signal outputted from a frequency divider 7 is counted by a counter 14, inputted through a bus 13 to a muCPU2 at every prescribed period so as to discriminate whether it exceeds the preset upper or lower limit value or not. If it exceeds the limit value as a result of the discrimination, the muCPU2 outputs a gate lock signal to a gate circuit 12 when the excess occurs n times, thereby stopping a signal for controlling the gate of the inverter from the gate circuit 12. The frequency dividing set value and the upper or lower limit value of the counted value are set by using an operation panel 16. In this manner, the signal which is outputted from the PLL circuit can be monitored without influencing a control system.

Title: Reflection type liquid crystal light valve element
Inventor: TAKUBO YONEJI
IPC: G09F9/30
Filed: 1989-05-31
Abstract: PURPOSE:To decrease the influence of scanning line and signal line potentials on picture element electrode parts and to allow high-quality display by forming reflecting picture element electrodes to the thickness of >=1/5 the thickness of a liquid crystal layer. CONSTITUTION:The picture element electrodes 105 on a substrate 101 is formed to the film thickness of >=1/5 the thickness of the liquid crystal layer 106. Namely, the liquid crystal light valve element of a reflection type is constituted by utilizing the parts exclusive of the spacings for electrically separating the adjacent picture element electrodes from each other as picture element parts and forming the scanning lines 102 and the signal lines 103 present via insulating layers 110 between the adjacent picture element electrodes. The liquid crystal electric field distribution of the picture element parts is, therefore, liable to be changed by the influence of the scanning line and signal line potentials but the influence on the liquid crystal electric field distribution of the picture element parts is sufficiently decreased by adopting the above-mentioned structure. The high-grade display is thus executed without lowering the contrast ratio as a light valve.

Title: Optical fiber gyro and its signal processing method and navigation system
Inventor: SONOBE HISAO
IPC: G01C19/72
Filed: 1990-05-30
Abstract: PURPOSE:To reduce the size and weight and to decrease the offset and drift by providing an optical system with a switch which turns on and off the light output of a coherent light source and providing a signal processing system with a function which detects and corrects a self-offset value. CONSTITUTION:When a command signal E6 is varied to zero in T1 at a period T2, the switch 8 turns on while the signal E6 is 1 and a command value E'p comes to Ep to apply a DC signal E8 to the coherent light source 1, so that the light output of an optical branch device 2a becomes a specific value. While the signal E6 is zero, on the other hand, the switch 8 turns off and the command value E'p becomes zero, so that the light output of the optical branch device 2a becomes zero finally. The output signal E3 of a synchronous detector 9, therefore, comes to have no variation due to an input angular velocity OMEGAin and while the signal E6 is zero, the value is only an electric offset value Ee. This offset value is detected by an arithmetic processing part 11 and stored and the offset value which is stored previously is subtracted from the value of the output E3 while the signal E6 is 1 to find the input angular velocity OMEGAin, so that an error due to the offset in a detected value OMEGAout is corrected.
