Patent JP-S59186411-A (JP)
Title: Variable gain amplifying circuit
Inventor: MORIUCHI HISAHIRO
IPC: H03G3/00
Filed: 1983-04-08
Abstract: PURPOSE:To expand an operating voltage margin and to reduce a chip in size by using two transmission gate MOSFETs which are formed in a well area in series and have sources connected to the well area in common as a switch means which connects a feedback resistance selectively. CONSTITUTION:When only transmission gate MOSFETs Q1 and Q2 are turned on, the feedback resistance R1 is connected as shown in a figure, so its gain G is Ri/R1. When MOSFETs Q3 and Q4 or Q7 and Q8 are turned on, the gain is represented as a similar expression including resistances R2-R4. Sources and the well area are made common in the switching operation of said MOSFETs as shown in a sectinal figure, so threshold voltages of the MOSFETs Q1 and Q2 are not influenced by the substrate effect. Further, the potential of the well area is determined in the off-state immediately according to the source side, so no undesirable charge is accumulated in the parasitic capacity of the well area and a latch-up state due to a thyristor phenomenon does not occur.

Title: Japanese data transfer system
Inventor: SHIRATORI SHIGEO
IPC: G06F17/21
Filed: 1986-03-19
Abstract: PURPOSE:To allow an operator to generate a Japanese sentense while the operator is viewing a display, instead of designating a transfer unit everytime, and to improve operability by judging KANJI(Chinese character) displayed on a display screen to be defined data through the operation of a character key following the operation of a conversion designation key. CONSTITUTION:A key decision part 42 detects the depressed state of a keyboard 41. If the state shows reading, data is stored in a read buffer 44, and if it shows a control key, it is controlled as the prescribed control signal. When a conversion key is depressed, a KANA(Japanese syllabary)/KANJI conversion dictionary is accessed according to the contents in the read buffer 44, and a corresponding KANJI is stored in a conversion candidate buffer 45. Simultaneously said KANJI is displayed at a position specified by a defined cursor address register 52. By depressing the conversion key, sequentially candidate KANJI change. When a target KANJI appears, the operator presses other keys, whereby a definition detection part 43 detects the definition and gives the effect to a display control part.
