Inventor: HAGI JUN
IPC: A23L15/00
Filed: 1989-06-13
Abstract: PURPOSE:To easily form a raw material having especially weak cohesivity into a spherical form by using a top-opened bowl-shaped vessel having two curved side walls, rotating the center axis of the vessel along a circular orbit having a prescribed radius and rotating the vessel as a whole in reverse direction, thereby constantly applying a circulating motion of a definite direction to the raw material. CONSTITUTION:For example, boiled egg is strained to obtain granules of 0.8-1.0mm in diameter. 1kg of the strained boiled egg is mixed with 100g of raw egg albumen, 100g of raw egg yolk and further 150-250g of sugar. The mixture is divided into prescribed portions of 30-40g and each portion is thrown into a bowl shaped vessel 10 of a forming machine. A circulating motion is applied to the bowl-shaped vessel 10 with a power source such as motor through gears and shafts. The bowl-shaped vessel 10 is not rotated by the above mechanism and only the material in the vessel is rotated in a state pressed against the inner circumference of the vessel 10 and compression molded to form a prescribed spherical food.

IPC: H03G11/02
Filed: 1981-09-18
Abstract: PURPOSE:To obtain a small gain for a low input signal and a large gain for high input signal, by controlling the amount of negative feedback with a nonlinear switching element. CONSTITUTION:Transistors(TRs) Q3, Q4 constitute a differential amplifying circuit and TRs Q1, Q2 form a current mirror circuit. A TRQ5 forms an emitter follower circuit.
