Title: Automatic switching system for two-dimensional encoded k value
Inventor: SUEZAKI EIICHI
IPC: H04N1/00
Filed: 1981-08-07
Abstract: PURPOSE:To minimize the defect of the receiving picture quality even if the code error due to the defect of the line state or the like is generated, by transferring a control signal to the transmission side in accordance with the result of the comparison between the count value of receiving compressed signal data and a reference value. CONSTITUTION:When a controlling part 1 is started through a line LINE by the transmission side, the controlling part 1 sets a reference value of the number of error lines to an error counter part 3 and returns the response signal to the transmission side. Then, the transmission side transmits successively desired compressed signal data (two-dimensional encoded K value) to a decoding part 2. In the decoding part 2, a one-dimensional encoded line is converted to a white- and-black binary signal; and when an error is detected in this line, it is counted by the error counter part 3. The next line is processed similarly; and when the processing for one-screen components of lines is terminated, the error counter part 3 compares the count value with the reference value, and a signal indicating whether the line state is good or not is transferred to the transmission side through the controlling part 1.

An engaging part 19 to be formed simultaneously with the bore of a core 1 is particularly positioned accurately to hold a rotor 12 by a jig in the case of forming the frame 4. When the bracket 7 is secured, since the leg 8 is formed with a slight gap between the frame 4, the positional relationship between the bracket 7 and the frame 4 becomes irrelevant.

Abstract: PURPOSE:To enable automatic transfer of specimen vessels by constituting the titled counter in such a manner that the specimen vessels are gripped in a sample supplying position and are transferred to the blood cell counter and further lifting thereof. CONSTITUTION:Sample cassettes A are intermittently transferred counterclockwise by one pitch each when a start switch 45 is pushed. A start command is then outputted via a cable 33 to a robot 1 upon arriving of the specimen vessel 30 at a sample sucking position P. The robot 1 starts operating, grips the vessel 30 by gripping claws 10, turns the vessel counterclockwise and stops turning when the vessel arrives at the analysis window port of the blood cell counter 3. Then, the robot advances an arm 39 by a prescribed distance. Whether the counter 3 is normal or not is decided by means of an LED 68 and a phototransistor 32. If the counter is normal, the vessel 30 is perpendicularly lifted and a start switch is turned on. A prescribed volume of blood is then sucked by a pipette 74 and the blood cells are counted in a blood cell counting part. The result of the counting is displayed on a CRT 69.
