Abstract: PURPOSE:To easily obtain a required flow rate with one switch operation in any case by providing a flow rate selecting switch and a return switch and operating these switches. CONSTITUTION:When a flow rate selecting switch 1 of an operation part 5 is operated, a display element 3 corresponding to each stage of the flow rate selecting switch 1 is, for example, lit and a sound emitting element 4 emits a short sound to report that the switch 1 is operated.

Filed: 1985-11-27
Abstract: PURPOSE:To obtain a homogeneous, high-quality mark, by calibrating the surface of a body to be marked to the absolute original point, and displaying the displacement of a supporting body for a transfer rubber roller. CONSTITUTION:A transfer rubber roller is lowered and moved to a position shown by a broken line. Then, an interval is not present, a projected light beam is shielded and a transmitted light disappears. Therefore a photoelectric conversion element 13 detects the absence of the transmitted light beam 10. An electric signal pulse is generated only at an instant when the projected light is shielded. At this time, the displacement of a supporting body 3a for the transfer rubber roller 3 in the direction perpendicular to the surface of an IC package is detected. A displacement display 5 displays the displacement based on the output of a linear scale 4. Said electric signal pulse is inputted, and the displacement display 5 is set at an initial state. When the transfer rubber roller is lowered, the numerical value is displayed on the displacement display 5. The value is displayed under the state the surface of the IC package 1 is calibrated to the absolute original point. When the display value is made to agree with a predetermined value beforehand, the pushing pressure of the transfer rubber roller can be made uniform.

Title: Lithium ion conductive polymer electrolyte
Inventor: AKASHIRO KIYOAKI
IPC: H01M10/05
Filed: 1987-10-20
Abstract: PURPOSE:To obtain a polymer electrolyte showing good lithium ion conductivity even at room temperature by using a specified polymer prepared by vinyl- polymerizing allyl polyether glycol as an organic polymer for the polymer electrolyte.
