Title: Lock mechanism for portable electronic apparatus
Inventor: NAGAHASHI TAKICHI
IPC: H05K5/03
Filed: 1994-07-20
Abstract: PURPOSE:To prevent a display part from being opened inadvertently when the grip of a portable electronic apparatus is lifted by a structure wherein a stopper is shifted in the direction different from the rotating direction of a cover body and engaged with the body when the portable electronic apparatus is transported while being suspended. CONSTITUTION:When a grip 3a is lifted with a body 1 and a display part 4 being closed, the grip 3a is bent gravitationally by the weight of the body 1 and the display part 4 and a core member 3b movable freely in the horizontal direction is translated in the central direction. A holding lever 9 coupled through a pin 10 with a coupling hole of the core member 3b is then rotated and the click is engaged with an engaging hole 4a at the display section 4 which is thereby held in closed state automatically. When the grip is released after transportation, the core member 3b slide resiliently outward to the original position and the holding lever 9 rotates reversely to disengage the click which is then contained in the body 1 thus unlocking the apparatus. This structure prevents the display part 4 from being opened due to inadvertent touching of a finger to an open/close lever when the grip is lifted.

Title: Semiconductor memory
Inventor: FUJITA SHIGEAKI
IPC: G11C11/407
Filed: 1988-07-06
Abstract: PURPOSE:To prevent oscillation due to GND level oscillation, etc., by executing the feedback of an internal synchronizing signal, which initializes an output buffer, to an internal synchronizing signal generating circuit and preventing the internal synchronizing signal from being generated when an output is changed. CONSTITUTION:When the comparatively large transistor of an output buffer 7 is operated, a large current flows and an internal GND level is oscillated. The oscillation of such an input signal is generated simultaneously with the operation of the output buffer 7, however, the operation of the output buffer 7 is activated by the internal synchronizing signal which is inputted to the output buffer 7. The feedback of the internal synchronizing signal, which operates the output buffer 7, is executed to an internal synchronizing signal generating circuit 8 and a power source to generate the internal synchronizing signal is turned off. Accordingly, the internal synchronizing signal can be prevented from being generated when the output is changed. Thus, the oscillation due to the fluctuation of the GND level can be prevented.

IPC: G06F3/0485
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To lessen processing load by efficiently carrying out scrolling process responding to the demand of scrolling. SOLUTION: When the center position of a display screen is at a position X(1), four sheets of map data M1, M2, M4, M5 are spread on VRAM. In the case of a scroll display in which the vehicle position is put on the center, when the center position of the display screen is moved to a position X(2), the spread map data is moved left side by a half. While the right half of map data M1, M2 being left, the left half of map data M7, M8 is added. Even at the time when the center position of the display screen is turned back to the position X(1) again, the center position is still in a region where scrolling can be done and map renewal is unnecessary. When scrolling is demanded by a joy stick, the left side is removed and the map data M7, M8 are spread in the right side.  A margin of scrolling in the right direction to reach the boundary is generated and a map displaying apparatus can meet the demand of high speed scrolling.
