Title: Reproducing device
Inventor: ISHIDA YASUHIKO
IPC: G11B5/187
Filed: 1985-08-19
Abstract: PURPOSE:To attain correct tracking by using a signal representing the relative relation between a head and a track to be reproduced so as to correct the relative position relation between the head and an object track based on a signal obtained through plural prescribed cores of the head. CONSTITUTION:A head unit 1 has one operating gap 2c and a head core 2 including core parts 2a, 2b divided substantially into two along the operating gap 2c and a winding is applied independently to the head core parts 2a, 2b. The head 2 is an on-track on one recording track 20 and levels La, Lb of a reproducing signal obtained respectively through both the cores 2a, 2b are identical. In comparing the levels La, Lb of a reproducing signal, when La<Lb, the head unit is moved in a direction where the on-track of the core part 2a is increased, and when La>Lb, the on-track of the core part 2b is increased to obtain a state B where the La and Lb are equal. Thus, correct tracking is attained.

Title: Pitch switchable mouth
Inventor: KUBO KENKICHI
IPC: G06F3/038
Filed: 1984-08-31
Abstract: PURPOSE:To attain both large and minute shifts of a cursor smoothly by switching the pitch according to the amount of shift of the cursor needed at a picture display part and to obtain a mouth which can vary the ratio of shift amount. CONSTITUTION:A mouth 10 contains switches 2 and 3 with decide the start and end points of the shift of a cursor. While rotors 4 and 5 which detect both the direction and the amount of the cursor shift are attached to the lower surface side of the mouth 10 together with a switch 13 attached to the side surface respectively. The pitch is changed by operating the switch 13. A control circuit of a display device contains a decoder 14 for shift amount, a selector 15 which switches the shift ratio of the cursor, i.e., a pitch a1 or a2 and a multiplier 16 which performs the arithmetic processing between a shift amount Xm of the mouth 10 obtained by the decoder 14 and the pitch selected by the selector 15. The pitch a1 or a2 is selected with operation of the switch 13, and the mouth 10 is shifted by a distance l. Thus the cursor shift amount L is obtained as L=a1l or L=a2l through an operation of the multiplier 16 for reduction or enlargement of the amount L. This improves the operability of the cursor.

Filed: 1983-09-30
Abstract: A multiprocessor system having a memory-programmable control of the type having a processor unit, coupling memories and input and output modules for transferring signals to and from a process which is to be controlled. Each processor unit is provided with a subprogram and a data memory which can be accessed directly, and a bus control unit releases access to the common system bus always for only one of the processor units.

In this manner, simple synchronization of the processor units is achieved. Moreover, guaranteed reaction times with respect to the process are possible. In addition to the duration, sequence, and frequency of the bus access of each processor unit in a bus cycle, the latest number bus window which must be seized by each processor unit can also be monitored by a bus monitoring device, thus insuring that guaranteed reaction times are possible.

Title: Image forming device
Inventor: NAKAZAWA NOBUO
IPC: G03G15/00
Filed: 1987-07-24
Abstract: PURPOSE:To eliminate the useless rotation of a photosensitive drum and to prolong the life of the drum by controlling mutual driving timing between an original detecting means and a recording carrier rotating means. CONSTITUTION:When a start key is pushed down, an illumination lamp 12 is turned on. And an optical system 12 is driven to proceed by an optical driving motor M2 in order to detect an automatic exposure mode or the size of an original and it is driven to recede after detection. When an automatic variable magnification is selected, the size of the original is detected and the magnification is decided from the size of the original and the size of copying paper in a cassette. When an automatic paper selection mode is selected, it is detected whether the size of the original coincides with the size of the copying paper in the cassette. And only when it is detected that copying is possible, a main motor M1 drives to rotate the photosensitive drum 1 so as to execute copying. Since an image carrier is not driven when the size of the original and that of the copying paper are noncoincident, the number of rotation of the image carrier is reduced and the life thereof can be prolonged.
