Title: Method of reducing resistance of conductive material
Inventor: SONODA NOBUO
IPC: H01B1/08
Filed: 1977-11-08
Abstract: PURPOSE: To exactly reduce the resistance of conductive material by simple method by treating the material of n-type metal oxide by metal halogenide of unsaturated oxide.  
     CONSTITUTION: Conductive material of n-type metal oxide such as, for example, In 2 O 3  or the like (or SnO 2 , ZnO) is treated by metal halogenide of unsaturated oxide such as, for example, SnF 2  or the like. This treatment is executed by immersing In 2 O 3  in SnF 2  solution (solvent is water or alcohol) or spraying SnF 2  solution to In 2 O 3 . Thus, (1) the reducing of the SnF 2  increases the lack of oxygen, and (2) Sn 4+  produced in the step (1) is substituted for the In 3+  in the In 2 O 3  to thereby increase the number of free electrons. Then, (3) F -  ion in the SnF 2  is substituted for the O 2-  ion in the In 2 O 3  to thereby increase the free electrons. Accordingly, it can reduce the resistance of the conductive material by simple method.

Abstract: PROBLEM TO BE SOLVED: To detect the call incoming signal of an outside line without interrupting a voice even just during communication between slave sets by synchronizing the control slot of a base unit with a communication slot at the time of communicating plural slave sets. SOLUTION: Just while speaking between slave sets is performed by using a channel f1 for communication between slave sets, a slave set PS1 receives the control slot from a base unit CS by switching that channel to a control channel fc. When there is an incoming call (ST52), the existence of call incoming of the outside line is reported to a slave set PS2 and processing for interrupting the communication with the PS2 under speaking is performed (ST55). Next, speaking for outside line speaking is started.  First of all, a link channel is established by using the control channel fc (ST57 and ST58), next, a burst signal containing synchronizing data is exchanged by an instructed slot (ST59 and ST60), when synchronism is established, a burst signal containing voice data TCH is alternately transmitted (ST61 and ST62) and the communication with a party connected through a telephone line to the base unit CS is started (ST63).

Filed: 1977-11-11
Abstract: PURPOSE:To prevent the effect on the output due to external disturbance and to reduce the distortion factor of the amplifying circuit, by feeding the signals of opposite phase each other of the differential amplifying circuit to two positive or inverting phase amplifying circuits. CONSTITUTION:The signal of opposite phase is fed to the input signal IN formed with the differential amplifying circuit 3 to the input of the positive phase amplifiers 1 and 2, the output is inverted phase signal each other, and BTL (Balanced Transformer Less) circuit is constituted.

In this case, a sound recording operation lever 10 is reset to a non-operation position by a reset spring. While a lock pin 8' of a rewinding operation lever 8 is locked to the lock groove of the 2nd lock lever 14'. Thus a tape high speed (rewind) reproduction mode is set to detect an inter-music no-signal part of a tape by a reproduction head. When a no-signal part prepared at the record starting point is detected under such conditions, a plunger 23 is actuated. Thus both a reproduction operation lever 9 and the lever 8 are reset to the non-operation positions by the reset springs and then stopped respectively.
