Title: Asynchronous data transfer system
Inventor: MORIIDE HIROYUKI
IPC: G06F3/06
Filed: 1979-11-27
Abstract: PURPOSE: To realize an asynchronous reading to the transmission state of data for the data group which is transmitted continuously or intermittently, by connecting the RAM having three memory regions for writing, temporary storage and reading each between the data transmission and reception circuits.  
     CONSTITUTION: The RAM having three memory regions for writing, temporary storage and reading is connected between the data transmission and reception circuits SEND and RCV. The writing of data into the RAM is performed by converting the asynchronous writing signal WRT produced after preparation of both the transmission address signal AST and the writing data DWRT into the writing signal synchronized with the data writing synchronous signal T3 through the synchronous circuit SINC. On the other hand, the circuit RCV gives the signal to the RAM and then reads the data in synchronization with the data reading synchronous signal T2. Thus the data group transmitted continuously or intermittently can be read asynchronously to the transmission state of data.

IPC: G05G5/06
Filed: 1989-06-14
Abstract: PURPOSE:To prevent the rocking of a control lever in all directions with no production of rust nor deformation by adding a pressing body to the rocker attached with a control lever in a control box, and bringing the pressing body into contact with the flat lower surface of the rocker. CONSTITUTION:A pressing body 57 is set under a rocker 42 in a control box 36 and brought into contact with the flat lower surface 58 of the rocker 42. When a handle 61 is turned toward a positioning pin 63, a push-up member 60 turns vertically to push up the body 57 and to press the rocker 42.

Abstract: PURPOSE:To avoid the use of a lot of local oscillators, by converting frequencies to a channel without changing each local oscillating frequency, in a repeater having two channels. CONSTITUTION:An oscillator 25 oscillates frequency difference between input waves f1 and f2 or f2 and f1(f1-f2) and the frequency of the input wave f1 or f2 and the difference are frequency-mixed at a mixer 24. As a result, in the output of the mixer, the f1 and f2 always exist independently of the input (either f1 or f2), and the signals can be transmitted on the different channel from that for the input wave, by selecting one of the input waves. When the local oscillation frequency is denoted as (f1-f2), the frequency f2 is included in the mixed output when the input frequency is f1 and the frequency f1 is included in the mixed output when the input frequency is f2, allowing to perform desired frequency conversion by picking up the frequency.
