Abstract: PURPOSE:To make it possible to regulate the temperature of upper blow-out air during bi-level mode, by adjusting the position of a damper means during bi-level mode to change the flow rate of cool air which is fed into an upper air take-out port through a bypass passage. CONSTITUTION:During bi-level mode, a damper 16 in an upper air take-out port 15 is located at the position N while a damper 18 in a defroster air blow- out port 17 is located at the position F, and a damper 20 in a lower blow-out port 19 is located at the position P.

Filed: 1989-06-26
Abstract: PURPOSE:To obviate the need to supply compressed air into a pneumatic device and discharge the same therefrom at every filling process and enhance the sealability near the opening of a container by a method wherein compressed air in an air operating chamber is once sent back into a compressed air chamber and it is thereafter supplied into the air operating chamber of a filling device which starts the filling operation so as to maintain the compressed air in a balanced state between these two chambers. CONSTITUTION:The part I of the Figure shows a position in which a retaining member 104 is in readiness for separation from a container 134 at the end of filling process and the retaining member 104 is moved upwardly by a roller 351 along a control cam 360 so as to reduce the volume of a pressure chamber 320, whereby the compressed air in its interior is sent through a conducting passage 322 into a compressed air chamber 311. The part III shows the position before the start of filling of the container 134 being fed and the retaining member 104 is moved downwardly by the control cam 360 and the roller 351 under the force directed downwardly by the compressed air in the pressure chamber 320, thereby increasing the volume of the pressure chamber 320. In doing so, the compressed air is sent into the compressed air chamber 311 in the part I and then through the conducting passage 322 into the pressure chamber 320 in the part III. Thus, the compressed air in the pressure chamber 320 is moved in a balanced state all the time.

Abstract: PURPOSE:To prevent magnetic flux concentration and to suppress the generation of a negative peak known as edge noise in reproducing wavelength so as to improve reproducing characteristics by cutting off the edge part of a magnetic substrate on the side where the substrate comes into contact with a nonmagnetic insulating material. CONSTITUTION:The terminal part 21 of the exposed surface of the magnetic substrate 11 which serves commonly as a slider for a medium-facing surface 17 and the return path of the magnetic fluxes for a main magnetic pole 15 and consists of a ferrite member (magnetic member) such as, for example, Mn-Zn or Ni-Zn and the surface which comes into contact with the nonmagnetic material 12 partly embedded in the substrate 11 and consisting of glass, etc., is cut away to a V-groove shape inclusive of the end edge 22 of the corresponding material 11 by machining, etc., and is thereby formed to the shape lacking the edge part. This cut part is then subjected to, for example, the treatment for embedding the nonmagnetic insulating material and a treatment for flattening the same. The concentration of the magnetic fluxes to the edge part is, therefore, prevented and the generation of the negative peak 23 relating to the edge noise is decreased. The reproduction characteristic is improved in this way.
