Title: Method and apparatus for ageing a catalyst
Inventor: CORKHILL WILLIAM JOHN
IPC: G01M15/10
Filed: 1999-12-01
Abstract: A method of ageing a catalytic converter 14 for use in vehicle development or testing comprises the steps of running an internal combustion engine 10 to provide fuel rich feedgases, injecting secondary air 18 into the feedgases, passing the feedgases through a reaction zone 13 where the feed gases are heated by reaction of the secondary air with excess fuel, controlling the air/fuel ratio of the engine and the volume of feedgases produced by the engine to a level such that the temperature of the feedgases entering the catalyst is in the range 1000{C to 1300{C, and continuing to run the engine for a period sufficient to degrade the emissions performance of the catalytic converter to a desired level. The catalytic converter is subjected to external cooling 20, 21 during the process to avoid damage to its casing.

Abstract: PURPOSE:To suppress an active material from coming off from an electrode at the time of manufacture so as to prevent an internal short-circuit from being generated by forming a porous protecting film of specific thickness in a surface of any active material applied layer of negative and positive electrodes. CONSTITUTION:A battery has a negative electrode 1 formed with a negative electrode active material layer 32 in a collector 9 and a positive electrode 2 formed with a positive electrode active material layer 33 in a collector 10. A porous protecting film 31 of 0.1 to 200mum thickness is formed in any surface of these positive-negative electrode active material layers 33, 32. In this way, during the time until an electrode is stored in a battery case 5, even when more or less contact is provided in the surface, since an active material is firmly connected to the protecting film 31, an internal short-circuit of the battery, induced by the active material coming off from the electrode to restick to the electrode surface, is prevented. Electrode reaction between the electrode and an electrolytic ion in the electrolyte is prevented from being disturbed.

Title: Electrophotographic copying method
Inventor: KUROKAWA JIYUNJI
IPC: G03G13/00
Filed: 1981-01-27
Abstract: PURPOSE:To enable a small-sized copying machine, by turning a rod shape photoreceptor formed with a specific photoconductive layer and turning it with an angle larger than the specified angle to obtain one sheet of copy. CONSTITUTION:As a photoreceptor, the photoreceptor forming a photoconductive layer made of a amorphous semiconductor with >=100 Vickers hardness and >=80 deg.C heat resistance on the circumference of a metal-made small-diameter drum, is used. While turning this photoreceptor, each process of charging, exposure, development, cleaning and discharge is made and the photoreceptor is turned at an angle larger than 360 deg.. A photoconductive layer is formed with an amorphous semiconductor and when this photoconductive layer is crystallized by temperature rise around the photoreceptor, the semiconductor does not function as the photoconductive layer. Thus, the photoconductive layer of the photoreceptor must not be crystallized by the said temperature rise and the accumulation of heat due to friction. This is referred to as heat resistance, and 80 deg. heat resistance means that the photoconductive layer is not crystallized even if the temperature of the photoreceptor reaches 80 deg.C.

Title: Heavy load transmitting belt
Inventor: TAKAGI SHINICHI
IPC: F16G5/16
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce wear at the beginning part of a slope and reduce backlash of a belt and generation of noise by respectively setting the contact faces of a block with a pulley and the contact faces of the blocks to each other to be in specific coefficients of friction. SOLUTION: Because a block belt is a mechanism transmitting power by friction of a block with a pulley, a first resin layer 10a requires high coefficient of friction to some extent. However, when the coefficient of friction is too high, the block is hardly drawn out from the pulley once wound to be undesirable. From such reason, such material having coefficient of friction in the range of 0.25-0.30 is used for the first resin layer 10a provided on the sides of the block. Meanwhile because between the mutual blocks, namely the front and rear faces contacting with others is required to set the coefficient of friction to be small, the coefficient of friction is set to be under 0.2.

Title: Automatic equipment for engaging on rack
Inventor: NAKAMURA IWAO
IPC: B65G49/02
Filed: 1982-01-25
Abstract: PURPOSE:To automate the conveyance of a processed flat plate, its engagement on a rack and the disengagement of the plate from it between the previous processing and plating of the plate, by electrically moving a flat plate receiving dish section, a rack fitting holder and a flat plate suction unit in connection with one another. CONSTITUTION:When a processed flat plate 5 is carried from a previous treatment process to a flat plate receiving dish section 4 by a belt conveyor 1, a sensor 6 acts to put a flat plate suction unit A into operation. Simultaneously with the rotation of the turntable 1' of the unit A and the descent of a shaft 3' in a prop 2', a sucking force is caused in the flat plate sucking part 8' of the tip of a movable arm 5' to suck the flat plate 5. After that, the shaft 3' is elevated, the table 1' is rotated and a motor 14' is turned by 90 deg. in a vertical direction so that the flat plate 5 is shifted from a horizontal posture to a vertical one. The arm 5' is then elongated so that the plate 5 is pushed and fitted into the holding claw 12'' of a rack engagement frame 2'' secured on a rack fitting holder B. At the same time, a switch 5'' is put into operation to stop the suction to separate the sucking part 8' from the fitting holder B.

IPC: H01L21/60
Filed: 1988-01-22
Abstract: PURPOSE:To effectively connect a copper wire to an electrode pad and to enhance the reliability of wire bonding by incorporating copper in the pad and increasing the hardness of the pad more than that of the pad containing as a main ingredient aluminum. CONSTITUTION:In case of wire bonding, the end of a Cu wire 6 is formed in a spherical shape to form a sphere 31, which is brought into contact with the electrode pad 5 of a semiconductor chip 4, ultrasonically vibrated to be rubbed with the pad 5, and press-bonded to the pad 5. In this case, the wire 6 has higher hardness than that of an Au wire or the like, but since the pad 5 is harder with 70-100 of Vicker's hardness value than 40 of the Vicker's hardness of the normal pad containing as a main ingredient aluminum, it can effectively bear the energy of impact, vibration of a capillary 30. Thus, the ball 31 can be secured to the pad 5 in a state that the boundary between the ball 31 and the pad 5 is preferable.

Title: Device for correcting lug part of plate for lead-acid battery
Inventor: TAKAHASHI KATSUHIRO
IPC: H01M50/541
Filed: 1992-01-24
Abstract: PURPOSE:To prevent the fall of the active material and the damage of a plate, and correct the deformation of a lug part of the plate simultaneously by performing the pressurization of a flat surface part of a plate and the correction of a lug part of the electrode plate simultaneously. CONSTITUTION:A pair of bar-shape rollers 1 for pressurizing a flat surface part of a plate from the upper and the lower and feeding the plate are provided, and a conical roller 2 is provided in one end of the roller 1. A flat surface part of a plate 3 is pressurized by the rollers 1 from the upper and the lower, and while the camber (condition A) of a lug part 4 of the plate 3 is bent to the direction reverse to the camber (condition B) by the rollers 2. When the plate 3 is passed through a correcting device, the lug part 2 is returned to the condition C by the elastic restoring force of itself to be flattened. Consequently, correction of the only lug part can be performed without damaging the plate. Simultaneously, since the plate is pressurized by the rollers, the adhesiveness of the active material to the grid net type material is improved.
