Title: Line accommodation class automatic setting system
Inventor: YABUUCHI KATSUMI
IPC: H04M3/00
Filed: 1989-04-11
Abstract: PURPOSE:To eliminate the need for the line accommodation class setting work with a maintenance personnel and to improve the maintenance performance by using a signal received from a line so as to identify whether the line accommodation class is an extension or a relay line thereby setting the line accommodation class automatically. CONSTITUTION:When an REC 21 of a COT 2 receives an input signal from a line, the REC 21 sends a control signal to a CTL 3. Thus, the CTL 3 discriminates whether the signal received by the REC 21 is an extension signal or a relay line signal and controls an SEL 13 to send a signal generated in the GEN 12 in the IOT 1 to a line in the case of the extension signal and the CTL 3 controls the SEL 13 so as to send the signal generated in the GEN 22 in the COT 2 to the line when the input signal is a relay line signal.

Title: Cage type induction motor
Inventor: IRIE SHINICHIROU
IPC: H02K17/16
Filed: 1979-07-23
Abstract: PURPOSE:To decrease secondary resistance in case of operation largely by a mechanism wherein conductor paths are also formed to the inside of a slot and an inner circumferential portion of a rotor, the each conductor path is short-circuited by meas of an end ring, and a secondary circuit of the rotor is up. CONSTITUTION:A conductor path 4a is formed into a slot 4 opening on an outer circumferential surface of a rotor core 2 and a conductor path 8a between an inner circumferential portion 8 of the rotor core 2 and a shaft 3, and each conductor path 4a, 8a is short-circuited by means of an end ring 9. Thus, secondary resistance becomes large because secondary currents collectively flow through an upper portion of the slot 4 and a conductor path 9a portion of the end ring 9 corresponding to the upper portion among the conductor path 4a when starting, and the secondary resistance largely lowers because not only the secondary currents uniformly distribute in the conductor path 4a but also the conductor paths 4a, 8a form a parallel circuit when normal operation.

Filed: 1986-04-22
Abstract: PURPOSE:To prevent damage due to combustion at those burner parts where no combustion shovld occur and generation of poisonous gases and to pnuuide a smaller size and lighter weight burner by providing fins on a burner body in order to cool the burner effectively in the direction of the flow line of air that passes through a blast route. CONSTITUTION:A burner 11 consists of a combustion section 11b where combustion is carried out, body 11a which supplies a mixture gas for combustion to a combustion section 11b, and fins 12 provided on the body 11a. The fins 12 are provided in the direction of the line of air flow. The air taken in from an air suction opening 17 by a fan 16 performs heat-exchanging and mixing with a high temp.exhanst gas generated in the purnerllor the high temperature heat in a combustion cylinder to become a hot blast. This hot blast is discharged into a room from a hot blast blow-out opening 18 by the fan 16. Because at this time the burner 11 in the combustion cylinder where heat is exchanged has increased heat radiation area due to the fins 12 attached to the body 11a, efficient heat exchange is made between the air taken in and the burner 11, preventing the temperature of the burner 11 from pecoming excessively high and heating the air for heat-exchange.
