Title: Gear pump
Inventor: ONO KEISUKE
IPC: C08L81/02
Filed: 1992-12-14
Abstract: PURPOSE:To contrive to reduce the noise at the running of a gear pump, to prolong its working and improve its pumping efficiency. CONSTITUTION:The gear pump concerned consists of a driving gear 1, a driven gear 2, a case 3, in which the two gears are internally installed, and a base 4 for enclosing the case 3. Its respective component parts are made by injection- molding material, which is prepared by mixing carbon fiber, tetrafluoroethylene resin and zinc oxide whisker with PPS resin. Due to the anisotropism relaxing effect of mold shrinkage factor by the zinc oxide whisker, the prevention of the wear due to malformation and the lowering of the noise due to vibration damping effect become possible. Further, due to the reducing effect of dynamic friction by the tetrafluoroethylene resin, the wear of the gears can by prevented from occurring. Accordingly, a low noise and long life gear pump can be realized.

Title: Digital video recorder for edtv television signal
Inventor: HIRANO YASUHIRO
IPC: H04N19/50
Filed: 1992-12-14
Abstract: PURPOSE:To reduce the deterioration of picture quality even in the case of an uncorrectable code error by substituting the vertical reinforcing signal of a zero component for the uncorrectable code error generated from the upper and lower pictureless part areas of a letter box type EDTV signal screen. CONSTITUTION:An external code ECC decoding part 15 prepares signals EFG1, EFG2 indicating code error areas for uncorrectable code errors. A code error correcting part 17 executes error correcting processing for substituting a zero component signal for an uncorrectable code error in the upper and lower pictureless part areas of the letter box type EDTV signal screen and substituting a picture signal having high correlation for the error in a picture area. A D/A conversion part 18 converts the processed signal into an analog signal to obtain a reproduced output signal V0. Consequently high quality pictures can be recorded/reproduced from any of TV signals NTSC, EDTV, and even when an uncorrectable code error is generated, the deterioration of picture quality can be reduced.

IPC: G06M3/00
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive and highly durable contact structure for a vibration sensor in which the number of steps can be exactly counted. SOLUTION: A spring 4 having a load for allowing an arm 3 rotating with a rotary shaft 2 as a center on a case 1 of a pedometer to float upward is integrated between the arm 3 and the case 1, and an upper stopper 5 and a lower stopper 10 are arranged at the upper and lower positions of the arm 3.

Thus, the arm 3 stopped in contact with the upper stopper 5 is allowed to overcome the load of the spring 4, and to start to move downward according to the vertical vibration of the body due to walking. When the switch contact 6 is pressed down, the switch operation is operated only between the switch contact 6 and the switch contact 7 without transmitting any electric signal to the arm 3 or the spring 4.  Thus, a highly durable contact for a vibration sensor with little contact failure can be obtained.

Filed: 1987-12-29
Abstract: PURPOSE:To reduce the extent of fluctuations in an air-fuel ratio as well as to make a variation in idling speed smaller by setting an exhaust feedback compensation factor to be zero when a vehicle driving state shift from an unlearning compensative control area to the specified learning compensating control area. CONSTITUTION:A control part 60 calculates a learning compensation factor by an exhaust feedback compensation factor and stores it in memory when a vehicle driving state is in the specified learning compensative control area preset, while it has such a structure that controls its learning compensation to compensate an air-fuel ratio by this calculation. An initialized function being added to the control part 60 hereat is one that sets the exhaust feedback compensation factor to be zero when a vehicle driving state shifts from an unlearning compensating control area to the preset learning compensative control area, and calculates the learning compensation factor by the exhaust feedback compensation factor, thereby performing the learning compensation control. With this constitution, even if the exhaust feedback compensation factor gets some slippage as far as a difference with a proper air-fuel ratio to be produced by a type difference and a secular change of an internal combustion engine 2, a variation in the air-fuel ratio can be made smaller.

Abstract: PURPOSE:To enable flexible expression of a relative difference in correctness of information from target detectors by providing a value using a Dempster- Shafer probability to introducing a ratio of uncertainty of what type the target is without being restricted by an addition rule. CONSTITUTION:Dempster-Shafer probability is used to introduce a ratio of uncertainty of what type a target is, namely, a ignorance value. Hence, by intentional operation of the value, a ratio can be converted softly as indicating a cause-effect relationship between types of targets and observation values of target detectors 102 and 103 to match difference of relative certainty of the devices 102 and 103. As a result, a relative difference can be expressed in information from the devices. Moreover, with the use of the Dempster-Shafer probability, information from the devices 102 and 103 is consolidated flexibly and easily according to a combination principle. Besides, a target sorter 101 applies a ratio of target type for each component device thereby allowing flexible adaptation to changes in the number of component devices.
