Title: Catalyst for low pressure degradation-desulfurization and its utilization
Inventor: YAMASE OSAMU
IPC: C10G45/08
Filed: 1992-09-16
Abstract: PURPOSE:To obtain a catalyst for effective hydrogenation degradation and desulfurization with a high degree of kerosene under a specified low pressure in spite of the presence of carbon dioxide by using an Ni ion exchanged body of Y type zeolite as a carrier and carrying Ni-Mo as a catalytic metal on the carrier. CONSTITUTION:An Ni ion exchanged body of Y type zeolite is used as a carrier and Ni-Mo as a catalytic metal is carried on the carrier to obtain the objective catalyst for low pressure degradation-desulfurization. Ammonium molybdate may be used as a component for carrying Mo and nickel nitrate or nickel sulfate as a component for carrying Ni. When the resulting catalyst is used, sulfur in kerosene is removed under a low pressure of about <=10kg/cm<2> and a compd. having a large number of carbon atoms contained in the fraction can be degraded to a compd. having a small number of carbon atoms. The catalyst does not lose its activity even in the presence of carbon dioxide and is effective for a degradation desulfurizer used before a steam reformer in a fuel cell system using kerosene.

Title: Sliding member
Inventor: OTANI TETSUYA
IPC: C23C14/06
Filed: 1989-10-19
Abstract: PURPOSE:To secure the characteristics of a CrN layer and to improve the conformability of a base material by forming a CrN layer on the sliding surface of a base material and further forming a Cr layer on the surface of the above CrN layer. CONSTITUTION:A piston ring 4 as a base material for a sliding member is fitted in a ring groove 3 in the outside periphery of a piston 2 corresponding to a cylinder liner 1 of an engine, and a CrN layer 6 is formed on a sliding surface 5. At this time, since delicate ruggednesses 7, 8 exist at the surfaces of the cylinder liner 1 and the piston ring 4, respectively, and a part 9 of the CrN layer does not easily wear, conformability between the cylinder liner 1 and the piston ring 4 is poor. Therefore, a Cr layer 10 is further formed on the CrN layer 6 so that the thickness of this Cr layer 10 is greater than the fall (a) of the ruggedness in the CrN layer 6. By this method, conformability can be improved by means of the wear of the Cr layer 10 while securing the characteristics of the CrN layer 6.

Title: Digital filter
Inventor: ISHIZAKI SUNAO
IPC: H03H17/02
Filed: 1984-12-24
Abstract: PURPOSE:To obtain two outputs in a small circuit scale by securing the partial share between a low band-pass filter and a band-pass filter. CONSTITUTION:An input signal is converted into a digital signal by an A/D converter 1. A delay element 5a receives the delay of a single unit time by the signal of a sampling signal generator 6 and is used as the input of a delay element 5b after undergoing the four rules of arithmetic. The inputs of both elements 5a and 5b are turned as they are into outputs and delivered through D/A converters 2a and 2b synchronously with the signal of the generator 6. These outputs of converters 2a(D/A1) and 2b(D/A2) are used as the outputs of a low band-pass filter and a band-pass filter respectively. Thus four multipliers and three addition/subtraction units are used. This decreases greatly the number of subtractors and simplifies the circuit constitution with high economical properties.

Abstract: PURPOSE:To increase the translational energy of a gaseous reactant, to decrease the collison rate between radicals and between the radical and raw material and to increase the film forming rate by providing a solenoid valve at a gaseous reactant blowoff port to pulse-control the gas flow rate. CONSTITUTION:A substrate 11 is placed on a substrate holder 8. The opening and closing of a solenoid valve 14 are pulse-controlled by a pulse signal source 15. A high voltage is impressed on an Ar gas discharge electrode 2, and the plasma discharge of the Ar gas is generated in a plasma discharge part 12 when the solenoid valve 14 is opened. An electric field is generated between the substrate 11 and a shield mesh 3, and the particles (radical) generated by the decomposition of the gaseous reactant are collected and deposited on the substrate 11 as a thin film. Since the gaseous reactant is supplied from a blowoff port 7 as a pulse, the pressure is enhanced at the blowoff port 7, and the translational energy is increased. Consequently, the second-order reaction of the chemical decomposition is controlled only by the electric field between the substrate 11 and mesh 3.
