摘要:
In fabricating an inner roller for use in an internal-meshing planetary gear construction, the outer periphery of an inner-roller blank 30c is chucked in the state in which depressive forces are equally exerted on the outer periphery in all the directions thereof by a chucking jig 50A, and the inner-peripheral wall of the blank 30c is subjected to a burnishing work in this state. The resulting inner-roller blank 30c is heat-treated in the state in which the depressive chucking is released, whereupon the outer periphery of the blank 30c is finished by grinding. It is accordingly possible to fabricate at low cost the inner roller which can suppress angular backlash owing to a smaller clearance defined between it and a mating inner pin, and which exhibits a high durability and favorable slip characteristics.

An inner roller 30 (in FIG. 2) for use in an internal-meshing planetary gear construction has its inner-peripheral wall 32 formed into a shape which is brought closer to a regular polygon of n sides (where n denotes an integer of at least 3, and n=3 holds in the illustrated example). Lubricating oil is reserved in clearances H1 defined near the vertices of the regular triangle, and an inner pin 7 is retained in light touch with the three middle points P1-P3 of the respective sides of the regular triangle. Thus, the reservation of the lubricating oil and the retention of the inner pin 7 free from backlash are made consistent, thereby to relieve the backlash of the planetary gear construction and to enhance the durability thereof. The shape of the inner-peripheral wall 32 closer to the regular polygon of n 7 is obtained in such a way that the inner-peripheral wall 32 is subjected to a burnishing work in the state in which depressive forces (deforming forces) based on chucking jigs are applied to the circumferential equidistant positions of the cylindrical blank of the inner roller 30, and that strains (residual strains) remaining after the burnishing work are further enlarged by a heat treatment.

摘要:
A semiconductor element or mobile terminal stores a user's biometric information pattern used for execution of a biometric authentication process and the residual number of trials indicating the number of allowed failures in the biometric authentication process, sends processing data to an external device so that the external device can use the processing data when the external device executes part of the biometric authentication process, and decreases the residual number of trials by a predetermined value while the processing data is output to the external device after start of communication with the external device.
摘要:
An apparatus includes an upper electrode and a lower electrode for supporting a wafer disposed opposite each other within a process chamber. A first RF power supply configured to apply a first RF power having a relatively higher frequency, and a second RF power supply configured to apply a second RF power having a relatively lower frequency is connected to the lower electrode. A variable DC power supply is connected to the upper electrode. A process gas is supplied into the process chamber to generate plasma of the process gas so as to perform plasma etching.
摘要:
A plasma etching apparatus includes an upper electrode and a lower electrode, between which plasma of a process gas is generated to perform plasma etching on a wafer W. The apparatus further comprises a cooling ring disposed around the wafer, a correction ring disposed around the cooling ring, and a variable DC power supply directly connected to the correction ring, the DC voltage being preset to provide the correction ring with a negative bias, relative to ground potential, for attracting ions in the plasma and to increase temperature of the correction ring to compensate for a decrease in temperature of a space near the edge of the target substrate due to the cooling ring.
摘要:
Disclosed are a method for assaying a target substance in a sample and an apparatus for the method. The method can specifically assay the target substance in the sample without using any antibody against the target substance. The assaying method includes simultaneously or successively bringing a labeled aptamer, the target substance in the sample and a solid phase into contact together, and then measuring the label of the aptamer which has not been bound on the solid phase. The labeled aptamer has a property of binding to the target substance. The solid phase carries an oligonucleotide immobilized on it in an excess amount relative to the target substance. The oligonucleotide is hybridizable with the labeled aptamer when the labeled aptamer is in a state that it is not bound to the target substance, but is not hybridizable with the labeled aptamer when the labeled aptamer is in a state that it is bound to the target substance.

An inexpensive multi-layered holographic read-only memory having a large capacity is provided. In the memory in which single-mode slab waveguides are multi-layered, a periodic scattering center whose period approximately agrees with the period of the guided mode is provided in at least one of a core layer and a clad layer in each waveguide so that a guided wave in the waveguide is diffracted by the periodic scattering center to the outside of the waveguide and a holographic image is generated.
