Title: High speed semiconductor memory
Inventor: MATSUURA YASUHIKO
IPC: G11C7/00
Filed: 1982-06-14
Abstract: PURPOSE:To improve the compatibility with conventional systems, to make the memory suitable for high density mounting and to attain high speed transfer with the same terminal number of memory element package as conventionally, by discriminating the read/write, page mode and nibble mode only with RAS and CAS. CONSTITUTION:A clock generator CLK-GEN is made enable with a detector and generates clocks by triggering the fall of the RAS or the CAS. The detector detects the operating mode of a memory element from the RAS and the CAS and generates a control signal of the CLK-GEN and CNT. In the section A, the RAS is made active (''L'' level) and the CAS is made active (''L'' level) after a delay time from the RAS to the CAS, it is the same as the normal read/write and page mode and it is not detected as the nibble mode. In the section B, since the RAS is toggled as ''L'' ''H'' ''L'' while the CAS is fixed to ''L'' and detected as the nibble mode.

Title: Developing device in electrophotographic copier
Inventor: NOGUCHI KOUJI
IPC: G03G15/09
Filed: 1978-08-18
Abstract: PURPOSE: To enable good developing to be performed even when the developer having high electric resistance is used by disposing a conductor on the surface of a stationary sleeve opposing to an electrostatic latent image holder in proximity thereto and grounding said conductor.  
     CONSTITUTION: A conductor 7 constituted by an aluminium foil or the like is bonded in strip form on the surface of a sleeve 3' opposing to a photosensitive drum 1 in proximity thereto and is at the same time grounded and therefore during the time when the developer 5 is conveyed on the insulated sleeve 3 surface and arrives at the neighborhood of the conductor 7 the insulated sleeve 3' surface has relatively large friction resistance and this causes the developer 5 to perform good rotation motion, thus its undesirable coagulation on the sleeve 3' surface may be prevented. On the other hand, even when the developer 5 having high electric resistance is used, the residual charges which the electrostatic latent images adsorbed with the developer 5 possess become easier to leak through the developer layer existing between the photosensitive drum 1 and conductor as well as the conductor 7, near the conductor 7.

Fluoric resin particles 8 bind these catalyst particles, and they 8 are so arranged that the density per unit weight of catalyst particles is low on the matrix 4 side and high on the electrode base material 1 side. According an electrode catalyst layer 16 having a high noble metal particles carrying density can have a large amount of giving noble metal particles even though the thickness is lessened, and the activating overvoltage and the concentration voltage and internal resistance can be lessened. This allows enhancement of the current and voltage characteristics and prolongation of the lifetime.
