Title: Oxidation catalyst composition
Inventor: DEBITSUTO JIYON ERIOTSUTO
IPC: C01B32/40
Filed: 1990-06-13
Abstract: PURPOSE: To obtain a catalyst for catalytic oxidation of carbon monoxide to carbon dioxide by depositing platinum metal on ceramic support with titania and by containing iron oxide which enhances the platinum, and alkali metal which enhances both. CONSTITUTION: The catalyst oxidizing carbon monoxide to carbon dioxide by free oxygen at about 10-50 deg.C is prepared by impregnating platinum metal, iron oxide and alkali metal into a titania or a ceramic porous support coated with titania. Iron oxide is an enhancing agent for platinum metal for oxidation at about 10-50 deg.C and alkali metal is also an enhancing agent for platinum metal and iron oxide. Therefore, an alkali metal is effective for catalytic oxidation for carbon monoxide.

IPC: F24F13/02
Filed: 1977-12-22
Abstract: PURPOSE: To simplify the construction and to exactly introduce the air into an operator's compartment for an overhead travelling crane by connecting a duct having a flexible sealing material perforated with an air inlet port through an air inlet duct having a flexible seal opening means to the compartment.  
     CONSTITUTION: An air inlet port 4a is perforated over the entire length of a flexible sealing material 4, which is internally secured onto the inside surface of a duct 3. This duct 3 is installed at the top of a building 1. The guide rollers 8 of an air inlet duct 6 having a flexible sealing material opening means 9 installed on the roof of an oerator's compartment C for an overhead travelling crane 2 are carried on the gide rails 5 in the building 1. When the crane 2 thus moves, the duct 6 is integrally moved with the crane 2 along the duct 3 to allow the means 9 to sequentially separate the sealing material 4 from the inside surface of the duct 3 to thereby open or close the inlet port 4a. Accordingly, clean air is exactly introduced into the compartment C upon movement of the crane 2, and the sealing material 4 is urged onto the inside surface of the duct 3 by means of its elastic property and the internal pressure in the duct so as to thus prevent the air from being leaked.

Title: Short arc electric discharge lamp
Inventor: MORI YASUKI
IPC: H01J61/86
Filed: 1988-06-23
Abstract: PURPOSE:To increase a total efficiency as an optical system by providing a specific condition among a lamp voltage immediately after start, a lamp voltage at the time for stable lighting-up, a distance between electrodes, a bulb inside diameter at the central part and a lamp electric power at the time for stable lighting-up. CONSTITUTION:Assuming that a lamp voltage immediately after start is VSL(V), a lamp voltage at the time for stable lighting-up, VL(V), a distance between electrodes, l(mm), an inside diameter at a place positioned at the central part of a distance between electrodes of light emitting tube bulb, D(cm) and a lamp electric power at the time for stable lighting-up, WL(kW), they are controlled by (VL-VSL)/l=510(V/mm) D/WL=1.8-3.5(cm/kW). When(VL-VSL)/l is less than 5, the distance between electrodes lmay be too large or the lamp voltage at the time for stable lighting-up may be too low, so that a function as a point source light is lost, and when it is larger than 10, the inside pressure of the bulb during lighting-up increases with the result that its reliability is decreased. When D/WL is less than 1.8, even if the diameter of an arc is narrowed down, the temperature of the bulb tube wall becomes too high until and when D/WL exceeds 3.5, narrowing-down of the arc is lost with the result that no improvement of a total efficiency will be recognized.

Such magnetic bars 4 can change the magnitude of the output voltage to 3 kinds according to the presence or absence of a bias magnetic field or the direction thereof. The recording medium safe to the falsification is obtd. by applying more intricate information. Since the decision of truth or falsehood is executed by the magnitude of magnetization, the discrimination of the large magnification is not possible with a magnetic viewer and, therefore, the higher safety to the falsification is obtd.
