Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide odor adsorption capability at ordinary temperature and enable odor components to be oxidation-decomposed by heating after adsorption by using a manganese-based oxide having decomposition activity of odor components, a carbon substance and zeolite with high adsorptivity. SOLUTION: The manganese-based oxide has the CuO:MnO radio of 2:1-1:10 and zeolite is ZSM-5 or β-zeolite and a carbon substance is graphite or activated carbon and the like. In this case if the carbon substance is not used, adsorptivity capacity of odor components decreases by about 70-80 percent compared with the case using the same. The mixture wt. ratio of the manganese-based oxide to the carbon substance is 10-20 and the mixture wt. ratio of the manganese- based oxide to the zeorite is 1:2-3. The manganese-based oxide is mixed with the carbon substance or with the zeolite and the carbon substance, pressure- formed and pulverized. The pulverized products are mixed with the zeolite or the manganese-based oxide and are formed to be the deodorization catalysts. Furthermore, heating the products by microwaves improves the decomposition activity of the manganese-based oxide.

Title: Liquid-level detecting apparatus
Inventor: ADACHI IKURO
IPC: G01F23/18
Filed: 1991-10-02
Abstract: PURPOSE:To make it possible to detect the level of liquid highly accurately in a broad detecting range by amplifying the output difference between the analog liquid level, which is obtained by converting the digital liquid level, and the actual liquid level of a level meter, and converting the difference into the digital value. CONSTITUTION:The pressure of liquid, which is inputted into a bath tub, is detected with a level meter 41. The detected signal is outputted as the analog signal. The signal is converted into the digital signal in an A/D converter 40. The digital liquid level H01 is outputted as the analog liquid level H02 from a D/A converter 50. The output difference between the liquid level H02 and the actual liquid level H00 outputted from the level meter 41 is amplified with a differential amplifier 54. The value of the liquid level H01 is corrected by the output of an auxiliary A/D converter 58. Thus, the entire liquid level range to be detected can be monitored with the liquid level H01 of the converter 40, which is outputted without the amplification of the output of the level meter 41. The highly accurate liquid level detection is judged by the correcting work based on the highly accurate detection of the conversion error caused in the digital conversion.

IPC: B60T7/12
Filed: 1994-10-20
Abstract: PURPOSE: To provide a means to release the holding condition of the braking pressure in the condition when a slope sensor output indicates that a vehicle stops on a downward-slope exceeding the second specific inclination, and a transmission is set in an advance stage; and to prohibit its operation automatically, when the auxiliary operation by an on-slope starting auxiliary device is obviated. CONSTITUTION: When a detecting output to indicate that a gear is shifted to the advance starting position from a gear-in switch 5, under the holding condition of the braking pressure, the output of a clutch stroke sensor 2 is picked up, a clutch stroke is depressed exceeding the first specific value to release the braking pressure, and it is confirmed whether it is reached to the second specific value or not. And when the clutch stroke has reached to the second specific value, the holding of the braking pressure by a solenoid valve 9 is prohibited so as to release the slope starting auxiliary operation, because a driver is going to start the advance on the down-slope conseously.

Title: Radio transmission system
Inventor: KASHIWAGI TAKASHI
IPC: H04B5/00
Filed: 1987-10-08
Abstract: PURPOSE:To reduce the transmission loss of a cable by covering the slot of a leakage coaxial cable by superconduction thin film to eliminate the radiation of a radio wave at the outside of a required part. CONSTITUTION:The slot of a leakage coaxial cable LCX of a cable 2' is covered by a superconduction thin film 10'. An external trigger function switching superconduction and normal conduction directly or indirectly is supplied on a train 1, then the superconduction thin film of the slot is switched into the normal conduction for a prescribed section approached by the train 1. Thus, since a radio wave radiated over all lines in a conventional system is limited only to a prescribed section where the train exists, then the transmission loss of the cable is reduced considerably.
