Title: Drying method of semiconductor wafer
Inventor: SATOU YASUHARU
IPC: B08B7/00
Filed: 1984-02-08
Abstract: PURPOSE:To dry a semiconductor wafer at a high speed by cooling to ice the moisture adhered to the wafer, and reducing the pressure to sublime it, thereby removing steam due to the sublimation from the vicinity of the wafer. CONSTITUTION:After a cover 14 is opened and a wafer 6 is cleaned with pure water, the wafer 6 is mounted on a cooler 13, and the cover 14 is closed. Liquid N2 is flowed to a tube 12, moisture 7 adhered to the wafer is indirectly cooled and iced. When a valve 18 is then opened to evacuate by a pump 19 so as to hold the wafer containing space at 0.8atm or lower, the ice is sublimed to become steam, and exhausted. When the ice is completely sublimed, a valve 16 is opened, clean air is filled, drying is finished, and the wafer 6 is removed. When the many wafers are set to a cassette 5, it is necessary to directly cool the adhered moisture.

IPC: A61K38/17
Filed: 1983-02-14
Abstract: PURPOSE:To obtain the titled substance having high immunospecific purity, in high efficiency by single absorption and desorption process, by using an adsorbent bonded with a monoclonal antibody obtained from a hybridoma cell produced by cell fusion. CONSTITUTION:The spleen cell of a mouse immunized with human transferrin (Tf) is fused with a myeloma cell by cell fusion to obtain a hybridoma cell, from which a monoclonal anti-human-Tf antibody is produced.

Title: Fuel feeder for diesel engine
Inventor: NAGATO KIYONORI
IPC: F02D1/02
Filed: 1988-02-01
Abstract: PURPOSE:To satisfy both low fuel consumption and torque demand during travel by enlarging the start supercharge region upto a predetermined engine rotation, when an engine is started with an accelerator opening higher than a predetermined level, thereby reducing the gear ratio while ensuring good start performance. CONSTITUTION:A controller 37 is provided with an accelerator signal for detecting starting condition, a vehicle speed signal and an engine rotation signal. When a starting condition with an accelerator opening higher than a predetermined level is detected based on the signals, the controller 37 provides 8 drive signal to an actuator 35 so as to project an operating rod 35a thus contracting an idle spring 20. Since the set load of a start lever 14 increases, start supercharge region is enlarged upto a predetermined engine rotation. Fuel injection quantity is incremented similarly at the start of engine so as to increase driving torque thus providing sharp hill start performance and start acceleration performance.
