Title: Deoxidizer
Inventor: AOKI MOTOHISA
IPC: A23L3/3436
Filed: 1979-09-26
Abstract: PURPOSE: To obtain a disoxidant for preservation of foods, fur or the like, which contains the ferrous carbonate, iron powder, halogenide metal and calcium aluminate hydrate and which has no increment of the pressure in accordance with the deoxidation reaction.  
     CONSTITUTION: The specific surface area and the crystal element of the ferrous carbonate are used preferably about ≤50m 2 /g and about ≥400Å respectively. And such ferrous carbonate is produced by giving the coagulating agent to the precipitate obtained by adding to alkali carbonate such as the sodium carbonate or the like to the ferrous salt such as the ferrous sulfate or the like with isolation of the air and then filtering and drying the coagulation with isolation of the air. The iron powder uses the reduced powder having the grain size of about ≤10 meshes, and then reduces the pressure of the group in progress of the deoxidation reaction. This property is just opposite to the ferrous carbonate, and thus the ratio of combination is decided for the both in accordance with the desired pressure. And the calcium aluminate hydrate absorbs CO 2  and discharge water. Thus the deoxidation effect can be increased, and then the pressure within this compound can be held constant substantially by the selection of the amount of combination.

Abstract: PURPOSE:To perform the fundamental operation for two kinds of cassette different in size by providing a means which transmits the rotating force to a vertically movable reel base and a means which automatically selects and sets the size of a cassette at the time of insertion of the cassette. CONSTITUTION:When a larger cassette is inserted to a cassette holder 12, microswitches 14a an 14b are made conductive, and a system control circuit discriminates insertion of the larger cassette to move a slide lever 22 in the direction of an arrow P.

Abstract: PURPOSE:To obtain an A-class bias circuit for a transmitter having high stability with small power consumption, by obtaining the bias value of a large current which is needed to an A-class action from a main power supply via a switching transistor. CONSTITUTION:The RF signal supplied from a terminal 1 is amplified by a transmission power amplifying transistor TR6 which has an A-class action and then transmitted to a load device (not shown in the diagram) via a terminal 18. A main power supply VCC is supplied to the collector of the TR6 via a choke coil 19. The feature of this invention is that a bias current of several 100mA which is needed for the A-class action is obtained from the power supply VCC. A microcurrent supplied from a terminal 7 gives a constant current action to a TR22 by means of a resistance R8 and a diode 23. As a result, a stable A-class bias current is supplied to the base of the TR6 via an area between the collector and the emitter of the TR22.
