Disclosed is a process for producing aragonite crystal form calcium carbonate with an acicular shape characterized by premixing aragonite crystal calcium carbonate and Ca(OH).sub.2 to prepare an aqueous slurry, adding a water-soluble phosphoric acid compound into the aqueous slurry, and introducing CO.sub.2 gas into the aqueous slurry to cause the carbonation reaction to take place. According to the present invention, aragonite crystal form calcium carbonate in an acicular shape with a large particle size is produced.

A drive plate includes a disk-shaped plate portion; and a tooth-shaped portion formed at an outer peripheral end of the plate portion. The plate portion and the tooth-shaped portion are integrally shaped from a single steel plate material. The plate portion and the tooth-shaped portion include a carburized layer provided over an entire surface layer of the plate portion and the tooth-shaped portion, the carburized layer having a carbon concentration higher than that of a center portion of the plate portion and the tooth-shaped portion in a thickness direction. The carburized layer of the plate portion is higher in hardness than the center portion of the plate portion in the thickness direction. The carburized layer of the tooth-shaped portion has been subjected to a quenching process, and is further higher in hardness than the carburized layer of the plate portion.

A manufacturing method and device for a drive plate that make it possible to obtain well-tensioned teeth at a ring gear portion while extending the life of a shaping die. A preferred embodiment provides a manufacturing device including: a compression punch that compresses a side wall portion of a raw material in an axial direction, the raw material including a bottom surface portion and the side wall portion which is cylindrical and provided to extend upright from an outer peripheral end portion of the bottom surface portion. A compression die disposed to face the compression punch in the axial direction and having a toothed shape formed on an inner peripheral surface. The compression punch contacts the compression die, and thereafter the compression die is pushed by the compression punch to form a toothed shape on the side wall portion while moving in the axial direction.

Computer readable instructions cause the server to generate, in response to receiving a request, first specific data. The first specific data comprises a first location information for location of first web data configured to display a message screen for specifying new setting information including the first setting information for the communication device. The first specific data is configured to be in a format for transmission using the protocol. The computer readable instructions further cause the server to generate, in response to receiving new setting information, a second specific data. The second specific data comprises second location information for location of second web data configured to display one or more instructions for transmitting the new setting information from the terminal device to the communication device using a short-range wireless communication. The second specific data is configured to be in a format for transmission using the protocol.

摘要:
A manufacturing method for a toothed member includes a thickened tooth shaping process in which a toothed shape is formed on a side wall portion while making a thickness of the side wall portion larger than a thickness of a bottom surface portion by relatively moving the compression die with respect to the restraint die and the pressure receiving member in the axial direction from the side of the opening end of the cup-shaped raw material toward the bottom surface portion. The manufacturing method being such that the thickened tooth shaping process includes applying a load against the restraint die such that the restraint die restrains the first surface and the second surface.
摘要:
A multi-gate structure is used and a width (d1) of a high concentration impurity region sandwiched by two channel forming regions in a channel length direction is set to be shorter than a width (d2) of low concentration impurity regions in the channel length direction. Thus, a resistance of the entire semiconductor layer of a TFT which is in an on state is reduced to increase an on current. In addition, a carrier life time due to photoexcitation produced in the high concentration impurity region can be shortened to reduce light sensitivity.

A clock device acquires time information representing present time from an external device at preset time intervals, corrects time of an internal clock based on the time information, calculates an error of the time of the internal clock based on the present time represented by the time information, and changes a first set value of the time interval based on the error. The changing updates the first set value to a second set value, which is m times the first set value when the error is smaller than a first threshold value, while updating the first set value to a second set value, which is n times the set value when the error is larger than a second threshold value larger than the first threshold value (m, n: positive values satisfying m>1, n
