Title: Scanning system for printer
Inventor: MATSUSHITA HIROSHI
IPC: B41J19/16
Filed: 1981-02-13
Abstract: PURPOSE:To achieve scanning without inclining a recording picture, by making the main scanning recording at the 1st rotation of every two rotations of a drum and shifting the recording head at the 2nd rotation along a drum surface for sub-scanning. CONSTITUTION:When a photoreceptor drum 4 is kept to a recording speed, a pulse signal outputted from a rotary encoder 2 is taken as a line synchronizing signal to start the scanning for picture write-in. In this case, the main scanniing is made at the 1st rotation of two rotations of the drum 4 and the sub-scanning is made by feeding a recording head 6 in step during the remaining one rotation. If no write-in information is present at the main scanning of time t3-t4, the  head 6 during that time is skipped and the sub-scanning can continuously be  made. In this case, if the required time for the sub-scanning is longer than the  time for one revolution of the drum, synchronism in phase is executed from a  time point t6 when the drum 4 rotates by an integer number after the end of  continuous sub-scanning to execute the next main scanning.

Title: Semiconductor device
Inventor: AKIOKA TAKASHI
IPC: H01L27/08
Filed: 1988-02-01
Abstract: PURPOSE:To secure a good high-frequency characteristic and a required breakdown strength value by a method wherein a second conductor layer which is connected, in an ohmic manner, to the side face of a first conductor layer used both to position an emitter and a collector while it is situated between them and to be extracted to a base electrode and whose width is controlled is formed in a self-aligned manner. CONSTITUTION:A first conductor layer 8 used to position an interval between an emitter region 5 and a high-concentration collector region 4 is formed; a second conductor layer 60 connected to the layer in an ohmic manner is formed at the side face. Because the N-type polycrystalline silicon 80 can be formed in a self-aligned manner with reference to the first conductor 8, the contact area of a base region 3 required to interlink the first conductor layer 6 with the base region 3 is reduced sharply. On the other hand, because the first conductor layer 6 decides an interval between the emitter and base regions 5, 3 and the P<+> type high-concentration collector region 4, its length can be set appropriately in correspondence to a required breakdown strength value. During this process, the width of the N-type polycrystalline silicon 80 has nothing to do with the length of the first conductor layer 8; accordingly, the contact area with reference to the base region 3 is not changed, and a high-frequency characteristic is not influenced adversely.

Filed: 1992-02-05
Abstract: PURPOSE:To obtain a small sized device where an image displaying bright colors on OHP or paper is obtained by making processing speed in a low speed mode to be 1/n ((n) is an integer) of processing speed of a normal mode. CONSTITUTION:When OHP mode is selected by pressing a mode selection key, changeover of the processing condition to improve the fixing function is carried out through control by CPU. Then, when the lowering of the speed is carried out, the operation speed of an image reading system A is changed over to the low speed of 1/n and the image reading is carried out. Therefore, the image reading is carried out with high density which is (n) times in the direction of sub scanning. On the other hand, the operation speed of laser writing units 24 to 27 is not varied but maintained constant. Then, when the processing speed is reduced to 1/n, image data is discarded for n-1 lines for every (n) lines of scanning or transported while being changed to white signals. Therefore, semiconductor lasers of the laser writing units 24 to 27 stop light-emission for n-1 scannings.
