Title: Original information reader
Inventor: ABE YOSHINORI
IPC: H04N1/04
Filed: 1985-07-10
Abstract: PURPOSE:To attain pattern change without increasing the memory capacity by adoting the constitution that a RAM is used as a threshold pattern storage memory for the scanner side and a threshold data is transferred from an external device and written in the RAM via a data bus. CONSTITUTION:When the scanner 2 is not in the original reading state, the transfer of a control command is informed to the scanner 2 through a command control line 24 and the control command such as a threshold pattern select signal for binar coding is transferred to a data bus 22. A host computer 4 stores sequentially the sent binary signal is built in picture memory. During the transfer of the binary signal, when it is required to transfer the control command such as threshold pattern change from the host computer 4 to the scanner 2, the idle time (blanking time) during data transfer is utilized, it is informed to the scanner 2 through the command control line 24 to transfer the control command from the data bus 22. Thus, the control command is transferred even during the transfer of the picture information signal in this way.

Title: Joint structure of instrument panel and pad
Inventor: KIKUTA MASAAKI
IPC: B60R21/045
Filed: 1980-10-31
Abstract: PURPOSE:To prevent such a danger as projection of a panel due to its breakage by arranging structure within a range against which a human may possibly stries his head to include no adhesion between an instrument panel and a pad. CONSTITUTION:A pad 2 is stuck to an instrument panel 1 during formation of foam of urethane and the like. However, a range against which a crew-member of the pad 2 may possibly strikes his head, is processed in such a way as to prevent the pad 2 from being stuck to the panel 1. Accordingly, even in case the crew-member strikes his head against the instrument pad due to a secondary bump and the interior panel is either broken or cracked, the pad itself is not broken but only elastically expanded or contracted. Safety can be maintained since there is no such fear as scattering of fragments of the panel out of the pad.
