That is, at the time of read completion as a normal read success, the error bit number is checked and the error bit information as the checked result is transferred to the host computer together with the two-dimensional code data. In the transferred host computer, the printing quality of the two-dimensional code is numerically evaluated based on the error bit information.

Filed: 1991-06-13
Abstract: PURPOSE:To quickly accept the request of a right of using a bus of high priority order to attain high processing speed by arbitrating the request of the right of using the bus at every one bus cycle, and changing the right of using the bus into the right of using the bus of the higher priority order at every one bus cycle. CONSTITUTION:In the case that one data transfer is executed by dividing it into plural bus cycles, an arbitration circuit 27 receives the requests of the right of using an external bus 15 from the request circuits 20 of an instruction prefetch unit 12 and an execution unit 14. At that time, the arbitration circuit 27 examines again the request of the right of using the external bus 15 requested at every one bus cycle in conformity to a signal to show the end of the bus cycle. The arbitration circuit 27 gives the right of using to the request of the highest priority order from among the requested right of using on the basis of the preset priority order, and if this priority order is higher still more, an external bus cycle in the course of execution is interrupted. Thus, the processing speed can be speeded up by accepting quickly the request of the right of using the bus of the higher priority order, and processing capacity can be improved.

CONSTITUTION:As for a picture taken by an image pickup device 1 at the time of the harvesting of the fruits and vegetables or the like, the numbers of the picture elements in the length direction and the width direction of this picture are detected, and a ratio is calculated from these detected numbers of the picture elements, and this calculated ratio value is compared with a set and stored prescribed value, and when the ratio value is over the prescribed value, it is detected that the harvest is malformed. Besides, when the ratio value is below the prescribed value, it is detected that the harvest is of normal form. Since it is detected whether the fruits and vegetables or the like are of the normal form or malformed at the time of the harvesting, screening is simple, and besides, the harvest can be screened in a short time.

Title: Switch for plane of polarization
Inventor: SUZUKI YASUO
IPC: H01P1/10
Filed: 1988-06-09
Abstract: PURPOSE:To reduce power consumption and the generation of heat by providing a magnetic core part outside a waveguide, forming closed loop structure in which a ferrite bar part positioning inside the waveguide is connected continuously to the magnetic core part, and winding a core across the waveguide. CONSTITUTION:The ferrite bar part 14 is arranged in the waveguide 12 with high conductivity such as aluminum, etc., and the coil 20 is wound in the periphery of the waveguide 12 on which the ferrite bar part 14 is positioned. And the magnetic core part 22 is provided outside the waveguide 12, and the closed loop structure is constituted by connecting the ferrite bar part 14 to the magnetic core part 22 continuously. Therefore, since a magnetic hysteresis curve can be formed in upright shape without generating a diamagnetic field, it is not required to supply a current only by supplying a coil current at the time of switching a plane of polarization, and even when the current is required, only a few amount of current is required. In such a way, it is possible to realize power saving, and to reduce the generation of the heat.
