Abstract: PURPOSE:To contrive a higher resolution without requiring complicated mounting, by providing a focusing means for linearly focusing a light image from each light-emitting element array head on an image carrier, and alaternately arranging light-emitting elements of the light-emitting element array heads. CONSTITUTION:The surface of a photosensitive drum 4 is preliminarily electrified uniformly by an electrifier 5, and optical signals from LED arrays 11, 21 of LED array printer heads 10, 20 are projected on the surface of the drum 4 through selfoc lens arrays 12, 22, thereby forming an electrostatic latent image according to information signals. LED elements 11a, 21a are alternately (staggeredly) arranged so that they correspond respectively to even columns and odd columns in the image formed on the drum 4. As a result, the mounting density of the LED elements is reduced to 1/2 of a conventional value, and since wires 11b, 21c in each of the LED arrays 11, 21 are led out to opposite sides, the mounting density of the wires is also reduced to 1/2 of a conventional value, so that the mounting density of component parts as a whole is reduced to 1/4 of a conventional value.

Title: Bus selection system for decentralized control system
Inventor: IHARA TADASHI
IPC: G06F13/374
Filed: 1984-06-14
Abstract: PURPOSE:To improve the using efficiency of a system bus with a reduced delay of transmission of a processor having low priority, by rewriting dynamically the device numbers of each processor communication channel PCH. CONSTITUTION:When a main processor MP recognizes that the transfer of data has a delay of a fixed period of time or longer from a subprocessor SP2, a PCHO sends a present device number DN2 and a new device number DN2' of a PCH2 to a data line DATA within a system bus SB. The DN2' has higher priority than a DN1 of a PCH1. Receiving the new number DN2', the PCH2 rewrites the number DN2 to DN2'. When a transmission request is given from the SP2, the data transfer of the SP2 is carried out even though the PCH1 of the SP1 is selecting buses since the PCH2 has higher priority.

Title: Electric contact
Inventor: BABA MASANORI
IPC: H01H1/04
Filed: 1987-05-20
Abstract: PURPOSE:To reduce the extent of contact resistance by performing the diffusion treatment of Cu and Ni after this Ni is coated on a substratum of the Cu. CONSTITUTION:A contact 12 of a permalloy 11 is formed as a total ratio solid solution by heat treatment for 15 minutes at a temperature of 900 deg.C after stacking an Ni plating layer on a substratum layer 13 of Cu where Fe is hard to do its thermal diffussion. Consequently, an Fe component to be contained in this permalloy 11 is almostnot thermally diffused to an electric contact, thus Fe is in no case made to appear on a surface of the contact 12. In consequence, contact resistance in the contact 12 is small, and it is stable against operating frequency. Accordingly, performance of electric parts including a reed switch or the like is thus improvable.

Filed: 1987-05-20
Abstract: PURPOSE:To protect write by a simple constitution, by providing a means for setting a write enable signal to an H level, when a write protect use switch is turned off. CONSTITUTION:When a write protect use switch 7 is ON, a write enable (WE) signal 5 which is inputted from a terminal 6 is inputted as it is to an IC memory 9, therefore, write and read-out of a data are freely executed.

In such a way, write of a data to the IC memory 9 becomes impossible, and only read-out can be executed.
