Abstract: PURPOSE:To restrict a reduction in strength of an opening and enable a positive fixing of a filter member to an external member to be attained by a method wherein the external member having the opening of the filter member is provided with a reinforcing rib for dividing the opening and one filter member is provided with a groove guided by this reinforcing rib. CONSTITUTION:In an interior heat exchanging unit 1, if a filter member 20 is inserted in an opening 16 of an external member 3, a left filter 22 is inserted into a left opening 18 and a right filter 23 is inserted into a right opening 19, respectively and thereafter a fixing piece 24 is pushed up to cause these two filter members to be stored in the interior unit 1 at once. At this time, a reinforc ing rib 17 is fitted to the groove 21 of the filter member 20 and then the filter member 20 is inserted into the opening 16 while being guided. Under a condition in which the filter member 20 is fixed to the opening 16, the fixing piece 24 of the filter member 20 is exposed from the opening 16. Therefore, a hand is applied to the projecting part 25 of the fixing piece 24 to push it downward, resulting in that the filter member 20 can be pulled out of the opening 16.

Title: Method for driving power transistor
Inventor: MAEDA SHIRO
IPC: H03K17/28
Filed: 1987-12-18
Abstract: PURPOSE:To drive a power transistor with the small number of components by using the element of a long storage type to one of plural switching transistors and to generate a dead time. CONSTITUTION:When a signal is inputted to an A point, a photocoupler PC and a switching transistor TR Q1 are switched with accompanying the input. When the TR Q1 is turned on, the TR Q2 of a next step is turned off. However, when the element of a long storage time is used for the TR Q2, a timing to be turned off is delayed. According to the switching of the TR Q2, following TRs Q3 and Q4 and a transistor TR for power are switched and the timing of the TR for power to be turned on is delayed. As a result, the turning on-time of the Tr for power is delayed only by the storage time of the TR Q2 and this goes to be a dead time td.
