Patent JP-H0411387-A (JP)
Title: Semiconductor memory
Inventor: NAKADA KAZUHIRO
IPC: G11C11/401
Filed: 1990-04-27
Abstract: PURPOSE:To increase the access speed by making all of plural transistors TRs, which are arranged in series, conductive in a block including a sense amplifier selected by a column decoder. CONSTITUTION:Sense amplifiers connected to a signal line SAP are divided into several blocks, and each block is provided with sense amplifier driving circuits 1 and 2 of the GND side part having the same constitution, and a signal line the inverse of SAN1 (the inverse of SAN2) is shared in each block. Respective gates of N-channel MOS transistors (NchTr) Q13 to Q15 are connected to column decoder control lines Y1 to Y3 respectively so that all of these transistors are turned on when a column address line YSW1 is selected by the sense amplifier driving circuit 1 and goes to the high level. In this case, the level of a signal line the inverse of SAN is quickly pulled down in the block of required sense amplifiers SA1 and SA2 because sense amplifiers are divided into blocks. Thus, the current capability is kept constant to increase the access speed.

Title: Waveform recorder
Inventor: KATOU MASAO
IPC: G06K11/00
Filed: 1978-09-14
Abstract: PURPOSE: To reduce the dot spacing in a recorder of multi-stylus system thereby to make the waveform data readable by interpolating the similar interpolating data between recording dots.  
     CONSTITUTION: An analog waveform signal is converted by an A/D converter 1 into the waveform data having digital codes, which are then fed to a data processing circuit 2. If waveform data such as A to D are given, a function indicating a straight line L 1  jointing the two points A and B is first calculated. Then, the value of the linear functions is calculated for each dot timing and is inserted as the interpolating data between the two points A and B so that the records E 1 , E 2  and so on are attained. Like processes are accomplished between the points B and C and the points C and D. Thus, the records which have a narrow recording dot spacing and which have a readable waveform can be obtained for each waveform data applied.

Abstract: PURPOSE:To warn an operator that an OPC drum is exposed to external light by giving a warning when a cover open state is protracted. CONSTITUTION:When the jamming of transfer sheet occurs in the transfer part or a pair of resist rollers 11 and 12 of the title device, the jammed sheet is removed by opening the opening and closing part 30 of an upper cover. When the opening and closing part 30 is opened, a projection part 33 connected to the said part 30 is disengaged from a cover opening switch 34, which is in an open state. If a certain time passes in a state where the switch 34 is still open, the warning such as a buzzer 41, etc., is given by a timer 39. Thus, the OPC drum 1 is not left in a state where it is exposed to the external light and the deterioration thereof can be prevented.
