A permanent magnet type rotor comprises an inner member 2 having an outer ring portion 21; an approximately annular outer member 1 having soft magnetism and an inner circumference contacting with an outer circumference of the outer ring portion; and plural permanent magnets 3 disposed at equal intervals on the outer circumference of the outer member toward the circumferential direction. At least one of the inner member 2 and the outer member 1 is made from a sintered material, and the inner member 2 and the outer member 1 are mutually sintered and bonded. Thickness and weight of a dynamotor itself can be reduced and high output and high efficiency can be achieved.

A communication apparatus is configured to include first and second cards, and a card-to-card link connecting the cards. Each card is communicably connected to another communication apparatus through a route connected to the card. One of the cards is determined to be a primary card that controls data transmission between the communication apparatus and another communication apparatus, and the other card is determined to be a secondary card controlled by the primary card. The primary card establishes a primary data-path for transmitting primary data, using one of the first and second routes connected to the primary card. The primary card further establishes a secondary data-path for transmitting secondary data, using the card-to-card link, the secondary card, and the other one of the first and second routes connected to the secondary card.

The cellular telephone device includes a control unit that executes any one of a plurality of applications, and a storage unit that stores an execution count of an application executed by the execution unit. The control unit determines an application to be executed after terminating or suspending a predetermined application, based on the execution count stored in the storage unit.

An electronic component mounting configuration in which an electronic component chip having a plurality of protrusion-shaped electrodes distributed on its entire mounting surface is mounted through protrusion-shaped electrodes on a printed circuit board is provided which is capable of improving reliability of an electronic component by relieving thermal stress. The solder bumps are arranged so that intervals between solder bumps adjacent to one another become smaller from a central portion of a mounting surface of the electronic component chip toward the peripheral portion thereof. For example, an interval between the solder bump “1A” arranged in the central portion of the semiconductor chip and the solder bump “1B” arranged in an outer side thereof, adjacent to each other, is set to a pitch of P1. An interval between the solder bump “1B” and the solder bump “1C” formed arranged in an outer side thereof, adjacent to each other, is set to a pitch of P2 and an interval between the solder bump “1C” and the solder bump “1D” formed arranged in an outer side thereof, adjacent to each other, is set to a pitch of P3 (P1>P2>P3).

In an SiC vertical MOSFET comprising a channel region and an n-type inverted electron guide path formed through ion implantation in a low-concentration p-type deposition film, the width of the channel region may be partly narrowed owing to implantation mask positioning failure, and the withstand voltage of the device may lower, and therefore, the device could hardly satisfy both low on-resistance and high withstand voltage. In the invention, second inverted layers (41, 42) are provided at the same distance on the right and left sides from the inverted layer (40) to be the electron guide path in the device, and the inverted layers are formed through simultaneous ion implantation using the same mask, and accordingly, the length of all the channel regions in the device is made uniform, thereby solving the problem.

The present invention relates to a relay device enabling efficient management of a voice message and a caller to wait for transmission of the voice message in a short time. The relay device is located at a boundary between an existing telephone network and an IP network, converts and relays a voice signal and an IP packet. The relay device comprises a receiving unit receiving voice source data into which a voice message is digitized, a packet processing unit converting the received voice source data into a voice source data packet as the IP packet, a storage unit storing the converted voice source data packets, and a transmitting unit transmitting, when transmitting a designated voice message to a designated destination, the voice source data packet corresponding to the designated voice message among the stored voice source data packets.

The fertilizer of the invention is a fertilizer containing a sparingly water-soluble phosphatic fertilizer and a urea/aliphatic aldehyde condensation product. The process for controlling inoganizing speed of urea/aliphatic aldehyde condensation product of the invention comprises adding to the urea/aliphatic aldehyde condensation product a sparingly water-soluble phosphatic fertilizer having special elution characteristics. The fertilizer of the invention and the process for controlling inoganizing speed of urea/aliphatic aldehyde condensation product of the invention make it possible to control the inorganizing speed of the condensation product without changing the particle size or form, that is, to control development of the efficacy of the condensation product used as a fertilizer. The fertilizers of the invention or the urea/aliphatic aldehyde condensation products whose inorganizing speeds are controlled according to the process for controlling the inorganizing speed of the invention can provide nitrogen components to plant in accordance with the periods of culture of desired crops and a pattern of absorbing nutrition. This is effective in saving of the number of additional fertilization or nitrogen components left in soil after the period of culture.
摘要:
A stator for use in a rotating electrical machine is constituted by arranging the prescribed number of stator units in the circumferential direction of a stator core having a circular ring shape. The stator units provide magnetic teeth that project inwardly in the radial direction of the stator core. Coils are wound about the magnetic teeth via insulating members. Each of the insulating members arranges thick portions that slightly project opposite to each other in the width direction of the magnetic tooth, wherein the thick portions are shifted in positions in the thickness direction of the stator core with respect to opposite sides of the magnetic teeth arranged opposite to each other. Thus, it is possible to noticeably improve the space factor in the stator.
