Inventor: DEERU DEE HAAMAN
IPC: H04N21/647
Filed: 1995-01-12
Abstract: PURPOSE: To attain filtering to an interference signal without eliminating energy from an outgoing signal of the interference signal by selecting total energy of the outgoing digital signal to be within a prescribed frequency band and selecting an out-band frequency for the interference signal. CONSTITUTION: In the case that a downstream spectrum obtained in a transmitter 102 is within a prescribed frequency band, very small downstream energy is transmitted at lower and upper side bands at the outside of the prescribed frequency band. A remote receiver 108 filters noise at the lower side band where dimmer noise is in existence without eliminating lots of energy from the downstream digital signal. On the other hand, the upperstream channel transmission for the upper side band range is attained without radiation restriction problem of a twisted wire pair. As a result, the downstream signal is not attenuated by the filtering in the receiver 108. Moreover, the frequency band is revised by changing parameters of the transmitter 102.

Title: Manufacture of foundation cloth for air bag
Inventor: MORIWAKI TOSHIJI
IPC: D03D1/02
Filed: 1995-01-12
Abstract: PURPOSE: To secure a non-coat air bag that is inherent in low permeability and excellent in pliableness and storability as keeping a necessary mechanical characteristic by applying steaming treatment to an air bag foundation cloth consisting of a synthetic fiber fabric. CONSTITUTION: When such one as subjected to steaming treatment is adopted to a synthetic fiber fabric forming an air bag foundation cloth, especially a non-coat air bag foundation cloth, restraint between those of single yarn and yarn filament of the fabric becomes lessened, given a puff, and further, since an interstitial part is phenomenized, such an effect that low permeability is improved as keeping a mechanical characteristic is securable. As for the synthetic fiber, nylon 6.6 or the like is used. As for fabric structure, a plain weave fabric is desirable for its excellent mechanical characteristics from the standpoint of thin cloth surface. On the other hand, as to steaming treatment, a batch method in which synthetic fiber fabric is treated in steam for a specified time, is applied.  Owing to such like characteristics, an occupant protection system by an air bag is thus spreadable.

Filed: 1990-01-12
Abstract: PURPOSE:To allow the easy formation of marks from the parts on the outside of groove sections into groove parts and to suppress crosstalks, etc., as well as to allow an increase in capacity with a small size by forming the recording film structure in the groove parts of a magnetic film so as to vary from the recording film structure in the parts exclusive of the groove parts. CONSTITUTION:After the grooves 31 are formed on a substrate 30 consisting of glass, etc., org. matter is sputtered to form trigger layers 33 on the grooves 31. The recording film 34 is then formed on the grooves 31 and the substrate 30. The thin film of the org. matter forming the layers 33 is lower in thermal conductivity than the glass forming the substrate 30 and higher in heat accumulation effect. The temp. difference between the grooves 31 and land parts 33 is increased at the time of irradiation with a light beam by forming the layers 33 in the grooves 31. The marks formed in the grooves 31 hardly spread to the regions exclusive of the grooves 31. The crosstalks, etc., are, therefore, suppressed and the increase in the capacity is attained with the small size.

Title: Detection method of throttle valve idle opening of internal-combustion engine
Inventor: HASEGAWA SHIYUNPEI
IPC: F02D41/18
Filed: 1982-01-14
Abstract: PURPOSE:To always obtain a signal of right idle opening by making a comparison between a detected value of a throttle valve opening sensor and a stored value of the present throttle valve opening and making the smaller value as an idle opening value of the throttle valve. CONSTITUTION:A value thetath of a throttle valve opening is made a provisional value thetaIDX of the idle opening. When the value thetath of the throttle valve opening is smaller than a stored value thetaIDL of the present idle, distinction is made at a step 5 if a value thetath of throttle valve opening at the last time is equal to a value thetath of the throttle valve opening at this time. A stored value thetaIDL of the present idle opening is replaced by the provisional value thetaIDX of idle opening at a step 8. Since a value thetath of the throttle valve opening shall not be made to a stored value of idle opening unless there are coincidence cases of said value, predetermined times even if a small value thetath of the throttle valve opening is detected temporarily due to noise and the like, erroneous setting can be avoided. Thus, a signal of right idle opening can be obtained at all times.
