A method for manufacturing a firm and rigid cam-cam shaft assembly, which comprises the steps: (a) molding a component having through-hole therein from a material of an alloy to be sintered, said material allowing the first ratio of the contraction of the inner diameter of the component at joining portion when the component is singly sintered to the inner diameter thereof before sintering to be more than 2%; (b) presintering said component; (c) assembling said component onto a metal shaft such that said metal shaft may be inserted into said through-hole; and (d) sintering said component assembled onto the metal shaft, whereby the joining of the component to the metal shaft is carried out in such a manner that the second ratio of the difference between the outer diameter of the metal shaft and the inner diameter of the contracted component after sintering to the outer diameter of the metal shaft is more than 2%.

The present invention relates to a method for fixing an annular element onto a shaft. The shaft may be a camshaft and the annular element may be a cam piece or a journal piece used in an automobile. The annular element is fixed onto the shaft by: engaging an axially extending projection of the element with an axially extending groove of the shaft so as to prevent a relative rotating motion; deforming an outer wall of the shaft adjacent to said groove at two positions near the terminating ends of the projection so that the outer wall protrudes into the groove, thereby fixing the element onto the shaft.

An information processing device for sequentially reading and executing programs stored in memory means, including: a program counter for outputting an address for reading a program to the memory means; an instruction decoder for decoding instructions read from the memory means in response to a control signal indicating a period in which the types of codes used in at least a field among fields constituting an instruction in the program are limited to a predetermined number or less; and controlled means for performing processing corresponding to the decoded results output from the instruction decoder. The instruction decoder has a reconfigurable circuit for changing the circuit configuration in response to the control signal so that the decoding is performed based on a relationship between codes in a field in which the types of codes used are limited and decoded results, the relationship being set so that the number of times of change of bit values in the field is reduced.

A transport system installed in a cleanroom where clean air is caused to flow from a ceiling toward a floor. The transport system includes a vehicle for transporting loads, and a guide rail suspended from the ceiling to guide the vehicle. The vehicle has a main body for running along the guide rail, a load supporting deck disposed over the main body, and connecting members for interconnecting the main body and load supporting deck. The guide rail is enclosed in a tubular cover defining an opening extending longitudinally of the guide rail for receiving the connecting members. The cover has a substantially streamline configuration with respect to the direction of clean air flows.

A stored instructions executing type timing signal generating system for flexibly generating a plurality of control timing signals having many changing points includes an instruction memory for storing a series of instructions stating contents of changes and relative time intervals between the changes of a series of control timing signals and a circuit for triggering the instruction execution by the absolute time for the series of instructions, so that after a first instruction has been executed, each succeeding instruction is sequentially executed on the basis of a relative time interval before the execution of a next instruction stated in the instructions, thereby to generate the control timing signals. The number of changing points of the control timing signals is basically dependent only on the number of words of the instruction memory, and therefore the plurality of control timing signals having many changing points can be generated easily.

A transporting apparatus is provided with a moving platform capable of moving vertically, an article loading platform that can be moved horizontally with respect to the moving platform, a contactless sensor provided on the moving platform, a detected member that is provided on the article loading platform, whose position can be altered between an position detected and a position not detected by the contactless sensor, and an operating member operatively linked to the detected member. The operating member can come into contact with an article loaded on the article loading platform, and changes the position of the detected member between the detected position and the non-detected position. Due to this configuration, it is possible to provide an article position sensor between the article loading platform and the moving platform without using wires, which are deteriorated due to the relative movement between the article loading platform and the moving platform.

A program control apparatus includes a memory for storing a REPEAT command to a first address, a calculation command such as sigma command to a second address after the first address, and another calculation command, such as a SUBTRACTION command to a third address after the second address. A repeat controller is operated in response to the REPEAT command for setting a repetition number. A first operation executor operates in response to the sigma command for executing the adding operation repeatedly by the repetition number. A second operation executor operates in response to the SUBTRACTION command for executing the subtraction in parallel to the adding execution in the first executor.

Herein disclosed is a process for forming a dispersion alloy layer on a metallic base. The powder of an alloy system, which will separate into two or more multi-liquid phases at a temperature equal to or higher than its melting point and will solidify, when quenched, with its individual liquid phases being separate and in which the ratio of the minimum to the maximum specific weight its individual liquid phases is 0.3 or higher, such as the powder of any alloy system of Cu-Ni(15%)-Fe(8%)-Si(3%)-B(1.5%) is applied to a metallic base. The powder thus applied is then melting and agitated while being irradiated with a laser beam oscillated. The agitated melt of the powder is then quenched to solidify with the movement of the laser beam thereby to form on the metallic base the dispersion alloy layer in which the solid particles of at least one of those phase such as silicide particles are dispersed in the matrix of the remaining one of the phases.

A production method for a sintered member includes preparing a raw powder, compacting the raw powder into a green compact having pores at the surface thereof, and sintering the green compact into a sintered compact. The production method also includes sealing the pores exposed at the surface of the sintered compact by at least one of plastically deforming and melting the surface of the sintered compact. The production method further includes forging the sintered compact by using a lubricant after the sealing.

An information processing method for coding a program to enable an information processing device having an instruction decoder having a reconfigurable circuit, comprises the steps of: simulating execution of the program to obtain a history of instructions executed; extracting a routine in which a number of types of codes used in at least a field among fields constituting an instruction is limited to a predetermined number or less, from the program based on the history; inserting an instruction for changing circuit configuration of the reconfigurable circuit at start and end of the routine; allocating codes so that number of times of change of bit values in a field in which the number of types of codes used are limited is reduced for the routine; and converting a program obtained in the step of inserting an instruction to codes according to the allocation for the routine.
