Title: Motor drive device and drive method
Inventor: KOBAYASHI YOSHINAO
IPC: H02P6/08
Filed: 2005-04-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor drive device and drive method capable of controlling a low-speed rotation.  <P>SOLUTION: An oscillation section 11 is composed of two oscillation portions of a first oscillation portion 11a and a second oscillation portion 11b having equal frequencies and different on-duty widths. An output of the first oscillation portion 11a and the second oscillation portion 11b is switched by a switching circuit 14 as a set pulse signal input into a PWM control portion 12. The switching circuit 14 is controlled by a low-speed control switching signal from a low-speed control switching signal terminal 13. The set pulse signal having an equal frequency and different on-duty is input into the PWM control portion 12. In the low-speed control, a current detection prohibition period is made short for removing a noise during switching the PWM control signal using the set pulse signal having a small on-duty to make a PWM minimum pulse width to be short. A current supplied to a DC brushless motor 7 can be reduced so that a generated torque of the DC brushless motor can be suppressed.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Filed: 2005-05-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a highly applicable vacuum heat insulating material having improved manufacturing quality by reducing the occurrence of wrinkle and the malfunction of sealing during manufacturing the vacuum heat insulating material.  <P>SOLUTION: When the vacuum heat insulating material 3 is manufactured, a through-hole 6 is previously formed in a portion of a facing 5 where wrinkle may occurs. Then, a heating member is pushed against a peripheral portion of the through-hole 6 and thrust to form a protruded portion. Thus, the vacuum heat insulating material 3 is obtained. The twist of the facing 5 resulting from the thickness of a core material 4 is absorbed by the peripheral portion of the through-hole 6. Furthermore, the heating member is pushed thereagainst to avoid the wrinkle on the surface of the facing 5. Even when the relatively thick core material 4 is used, it is thermally welded to the edge of the core material 4 without fail. The occurrence of the wrinkle on the surface of the facing 5 is suppressed even for the vacuum heat insulating material 3 having the plurality of core materials 4.  <P>COPYRIGHT: (C)2007,JPO&INPIT
