Title: Negative feedback amplifying circuit
Inventor: MITSUO HIDEYUKI
IPC: H03G3/12
Filed: 1981-01-29
Abstract: PURPOSE:To vary the gain stably over a wide range, by making the closed loop characteristics stable through the change between a plurality of variable elements with a prescribed relation. CONSTITUTION:An input signal from an input terminal 1 is amplified at an amplifying circuit consisting of transistors (TR) TR2-4, and outputted from an output terminal 5. On the other hand, a feedback circuit consists of resistors 6, 7 and a part of the output is fed back to the TR2. Denoting resistance value of resistors 6-10 as R6-R10 and when R6>>R7 is taken, the closed loop characteristics mubeta being the product between a transfer function mu of the amplifying circuit and that beta of a feedback circuit, is expressed as mubeta=R8XR9/R6XR10. When the resistors R6, R8 are changed as R8=K1XR6 (where K1 is a constant), mubeta= K1R9/R10 is obtained and K1, R9, R10 are constants, allowing to make the closed loop characteristics constant. Thus, even if the grain is changed over a wide variety, stable operation can be made.

Title: Multi-layered bag
Inventor: SAITO HISATOSHI
IPC: B65D30/10
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a troublesome pre-processing process such as pushing-in of a layered bag comprising an inner layer bag for storing objects to be stored inserted into an outer layer bag and to avoid a mixture of foreign matters into the bag by at least overlaying sheets on a base of both inner and outer layers for sealing. SOLUTION: The multi-layered bag 1 is simultaneously formed as a cylinder by an inflation ply separation process and is formed as a double bag comprising an outer layer bag 2 and an inner layer bag 3 where opening ends on upper and lower parts are overlaid and sealed. The inner layer bag 3 is filled with objects 7 to be processed, and both inner and outer layer bags 2, 3 are formed with an upper end seal 5 and a base seal 6. A lubricant (talc) may be provided in advance between a gap 4 between the outer layer bag 2 and the inner layer bag 3 in this case.  Thus the gap 4 between the outer bag 2 and the inner bag 3 prevents external movement from transmitting directly to the inner layer bag 3, whereby even if the outer layer bag 2 is broken or receives shock to cause a pin hole, the shock may not be directly transmitted to the inner layer bag 3, avoiding the influence exerted on the bag 3.
