Penicillin Dryer
This unit turns at high speed a disk to which a bottle filled with penicillin is fixed to exhaust air and dry penicillin quickly. This unit increases the productivity of penicillin 300 to 400 times.

High-Frequency Sewing Machine
This unit glues synthetic resin such as vinyl chloride while pressing it zigzag. During the Korea War, when the U.S.A. ordered plenty of cover sheets for packaging weapons from rubber manufacturers, these sewing machines achieved brilliant success.

Microwave Channel Filter
This unit composes plural radio waves or takes out a specified radio waves from composed waves. In a relay station of telephone circuits, this unit is used to take out necessary radio waves. When microwave circuits were laid between Tokyo and Nagoya, and Nagoya and Osaka in 1952, the then Japan Telegraph and Telephone Public Corporation (NTT at present) recognized the Company as a designated manufacturer of Branching Filter.

Common Use Antennas Unit for Mobile Phone
This unit realizes common use of an antenna for plural radio waves. The Company delivered these units to meet the full operation of mobile telephones (for automobiles) between Tokyo and Nagoya, and Nagoya and Osaka in a term from 1975 to 1980.
