Title: Flash memory
Inventor: TAKEHANA KENICHI
IPC: G11C16/02
Filed: 1994-05-27
Abstract: PURPOSE:To prevent occurrence of memory cells in an over erasing state by forming a writing control circuit at the time of erasing, and performing thinner writing than the normal writing in a prescribed number or less of erased memory cells. CONSTITUTION:A writing control circuit 17 at the time of erasing is formed from a discriminating circuit 18 for the number of unerased cell, a storage circuit 19 for unerazed memory cell/address and a control circuit 20. At the time of erase verifying, a judging circuit 18 judges whether the number of memory cells which judged as in an unerased state by a data comparator 16 is made less than a prescribed numbers or not. When the judging circuit 18 judges that it is less than the prescribed numbers, the control circuit 20 makes the storage circuit 19 stone the address of a memory cell in unerased state. And the control circuit controls an writing/erasing timing generation circuit 15 and the like so that extremely thin writing is performed with a pulse having a shorter width than a normal writing pulse width for a memory cell in an already erased state before the next erasing operation is performed. Thereby, occurrence of memory cells in an over erased state is prevented.

Title: Printer system
Inventor: DOI JUN
IPC: B41J19/96
Filed: 1989-05-09
Abstract: PURPOSE:To prevent a printing result from becoming higher in density and a moire stripe pattern from occurring even if the thickness of a recording sheet is changed by a method wherein a feed amount is changed in the lap printing of a dot line printed on a just previous line and a dot line to be printed on a next line. CONSTITUTION:When a recording sheet thickness detection result is inputted to a CPU element 13, it sends printing data, a printing start command, and the like to a printer 11 to start printing. Then, the printer 11 prints the data for one line while keeping a height for several dots, thereafter conducting a paper feed action for printing a next line. At this time, if a printed matter is judged to require a thickness necessitating a lap printing, the CPU element 13 of a host 100 determines a paper feed amount with the digital data of a recording sheet thickness previously received from the printer 11 as reference, thereafter issuing a paper feed instruction optimum for the recording sheet thickness to a printer system. The set printing and paper-feed action are repeatedly conducted until the printed matter assigned by a user is completed.

Title: Position control device and compensating optical device
Inventor: KASHIBA SEIICHI
IPC: G03B17/00
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To move a travel member to such a position as a stoppage target by moving the travel member from one of preset positions to the other position, and making a distance smaller than the moving distance of the travel member between a mechanical restriction part and the other position. SOLUTION: Electric power is first energized to an A-phase and a travel member is driven to a position (d) at the eighth step as the nearest A-shape position, provided that the position of the travel member before driven is at a position (e) at the ninth step in a direction from a disengagement position toward an engagement position. Then, the travel member is driven toward a stoppage position along a line 3 eight step in advance of a line 1 as an in-phase feed line. Also, the edge of a ground plate is set so as to come to a position approximately three steps dislocated from a rotor position (a) in a lock ring engagement state toward the outside of a range between disengagement and engagement positions. According to this construction, a force to move the travel member along the line 1 becomes strong before a stepping motor arrives at the half period of the power feed phase.  Thus, the advance of the energization phase is stopped and fixed to the engagement position of the stoppage target position. Furthermore, the travel member temporarily moves beyond the engagement position, due to inertia, but is immediately pulled back.
