Title: Liquid pump device
Inventor: NOOMAN EFU TEIRAA
IPC: F04F5/10
Filed: 1989-03-13
Abstract: PURPOSE: To allow solid transported articles such as live fish to be transported under pressure without being damaged by discharging a primary fluid tangentially to a Coanda surface and transferring a secondary fluid along a central axis of a pump to surround the Coanda surface. CONSTITUTION: A secondary fluid is discharged from an inlet 14 of a main duct 12 upstream of and separated from an annular Coanda or convex surface 16 in the vicinity of an annular orifice 18. On the other hand, a primary fluid is discharged tangentially to the convex surface 16 via the annular orifice 18. The primary fluid is supplied from a plenum 20, and the plenum 20 is supplied with the primary fluid from a blade type pump 22 arranged in an auxiliary tank 24. The secondary fluid is attracted by the jet of the primary fluid, and liquid pressure is reduced on the convex surface 16 to promote the flow of the secondary fluid. In this way, solid transported articles such as live fish in the secondary fluid are protected.

Title: Braking device for motor
Inventor: KANAYAMA KATSUMI
IPC: H02P7/00
Filed: 1980-05-01
Abstract: PURPOSE: To increase the electromagnetically braking force for a motor by shunting a current caused by the counterelectromotive force produced by the inertial revolution of the motor via two transistors and operating one of the transistors as a reverse transistor.  
     CONSTITUTION: A motor M for a tape recorder or the like is connected between the connecting points of P-N-P transistors Q30, A40 and N-P-N transistors Q10, Q20, the Q30, Q20 are conducted at normal revolution by a controlling circuit 32, and the Q40, Q10 are conducted at reverse revolution, thereby driving the motor M. Further, the Q10, Q20 or the Q30, Q40 are conducted to shunt the counterelectromotive force current caused by the inertial revolution at braking time, thereby electromagnetically braking the motor. Since the braking current flows through the transistor having less voltage drop and the collector and emitter path of the reverse transistor, it can effectively brake the motor until the counterelectromotive force of the motor is considerably reduced.

IPC: H01L21/302
Filed: 1984-03-27
Abstract: PURPOSE:To reduce the etching rate in the peripheral region close to the orientation flat for ensuring good uniformity in the etching, by forming a section on a supporting electrode of a material serving to reduce the etchant. CONSTITUTION:A wafer 104 covered with an aluminium film is transferred to a predetermined position on a table 112 in a reaction chamber 101, which is then evacuated through an exhaust tube 109. After that, a reaction gas is introduced into the chamber through gas injection openings 108 from a gas inlet tube 110. High frequency power is applied between a supporting electrode 102 and an opposing electrode 103 by a high frequency power source 107, so that etchant is produced by electric discharge, and the aluminium on the surface of the wafer 104 can be etched thereby. The surface of the supporting electrode near the orientation flat is made of a material absorbing or comsuming the etchant, so that the density of the etchant is reduced in that region, and therefore the rate of etching is reduced in the peripheral region close to the orientation flat. Accordingly, the uniformity of etching in a wafer can be improved.
