Title: Semiconductor memory
Inventor: ISHIKAWA MASAHIKO
IPC: G11C11/407
Filed: 1994-05-23
Abstract: PURPOSE:To prevent deterioration of read-out margin due to reset timing of an external/RAS signal and an external/CAS signal by forming a control circuit controlling a RX generation circuit by CDE. CONSTITUTION:An internal RAS signal rises by a /RAS buffer circuit 12 by reset of an external/RAS signal. A word line driving signal RX falls by a RX generation circuit 13A by rise of this internal RAS signal and fall of CDE. And, a level of a word line WL falls by a row decoder 8. Also, a control circuit 1A generates CDE by an internal ATD generation circuit 14, a PEA generation circuit 15, a CDE generation circuit 16 by fall of the external/RAS signal. And CSL is generated from the CDE and a column pre-decoding signal by a column decoder 5. Thereby, a time out function can be given to column group signals, too.

Title: Photographic processing liquid and method for handling waste liquid thereof
Inventor: HAKAMATA HARUO
IPC: G03D13/00
Filed: 1987-05-01
Abstract: PURPOSE:To prevent an operator from touching a photographic processing liquid (waste liquid) by solidifying the waste liquid in a container in which the photographic processing liquid is housed and discarding the same after a photographic processing by using said container is carried out.

Title: Paper conveyance method of printer and device thereof
Inventor: SATO HIROSHI
IPC: B65H9/14
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To convey paper stably and enable the entry of head of paper securely by controlling in such a way that a paper feed roller rotates when a paper detection member detects a tip fringe of paper and inserting the tip fringe of paper into a contact part of the paper feed roller and an auxiliary roller without hitching the tip fringe of paper by the paper feed roller. SOLUTION: A drive motor is driven based on a control command from a control means to convey only one sheet of uppermost paper 2 in the direction of paper conveyance. When a paper detection sensor S detects a tip fringe of the paper 2 which is conveyed, a paper feed roller 13 begins to rotate in the direction of paper feed. Consequently, even if the tip fringe of the paper 2 knocks against a minute projection, it is securely inserted into a contact part of the paper feed roller 13 and an auxiliary roller 14 without being hitched in accordance with the rotation of the paper feed roller 13. Since the paper 2 whose tip fringe is brought in contact with the contact part is firmly gripped by the paper feed roller 13 on which the minute projection is formed and is conveyed in the direction of conveyance, precise entry of head becomes possible.
