Title: Electron beam generator
Inventor: SAITOU SHIYUUICHI
IPC: H01J37/24
Filed: 1983-10-13
Abstract: PURPOSE:To enable both the density distribution of a beam current and the level of the beam current to be effectively controlled by installing a cathode having a long electron-discharging surfase, the first grid having the same electric potential as the cathode and the second grid having an electric potential independent of the electric potential of the first grid. CONSTITUTION:The central hole 8 of the first grid 6 has a rectangular shape similare to the shape of an electron-discharging surface 2. The central hole 9 of the second grid 2 has a circular shape. The middle point between resistances 11 and 12 is electrically shorted from the first grid 6, so that the electron-dischargint surface 2 and the first grid 6 have almost the same electric potential. To the second grid 7, a bias voltage positive or negative to the electron-discharging surface 2 and other parts is applied from a variable d.c. bias power supply 13. The anode 4 is made to have a high electric potential positive to the electron-discharging surface 2 by a d.c. high voltage power supply 13. Owing to the above constitution, it is easily possible to properly adjust the magnitude of a beam current, the current density distribution in the cross section of the beam current and the shape of a beam.

Title: Line speed detection system
Inventor: SONE YUKIO
IPC: H04L29/08
Filed: 1989-07-26
Abstract: PURPOSE:To discriminate a normal character data speed in succession to a speed detection character by allowing a line speed detection means to calculate the line speed when a detection means detects a prescribed number of rising or falling. CONSTITUTION:A rising or falling detection circuit 10 detects the rising or falling of a speed detection character sent from a reception signal line. A clock circuit 40 gives a clock signal of a prescribed period to the circuit 10 in this case to calculate the rising or falling time. The rising or falling and time information is stored in a rising or falling storage circuit 50 and used to reproduce the speed detection character as a normal character. When a speed calculation circuit 20 based on a prescribed logic designated by the line offer company detects a prescribed number such as 2 of rising or falling, the circuit 20 calculates immediately the line speed by using the time information from the circuit 40.

Filed: 1988-07-30
Abstract: PURPOSE: To prevent an imposture practice and to allow the customer to calculate the price by providing a computer system receiving data transferred from a data read means and a weight measurement means with respect to each purchased article, comparing the data and storing the data. CONSTITUTION: The customer passes purchased articles on a scanner 16 one after another and allows a computer to confirm information of the articles such as weight, price and name of the articles. The total weight of the purchased articles put in a reception package 12 is calculated by a scale 14 under the package 12 and compared with the total registered weight of the purchased articles in the computer and an alarm is raised when they are in excess of a prescribed enable range. The customer brings the package 12 to a cashier after the weight is summed and the final weight is measured. Thus, it is warranted that nothing is added to the package after the weight measurement. Furthermore, by using article codes together with the name of the articles and the weight, the purchased articles at a low price after scanning are not replaced with expensive articles by an imposture practice.

Title: Restarting method for subordinate device of composite controller
Inventor: WATANABE TAKAO
IPC: G06F11/14
Filed: 1981-11-30
Abstract: PURPOSE:To shorten the time required for the recovery of a follower device, by restarting the subordinate device after confirming by a primary device that the command information stored in the follower device is not destructed when a fault of the subordinate device is recovered. CONSTITUTION:A primary device transfers plural commands to a subordinate device to decide the characteristics of the subordinate device. Thus the subordinate device stores these commands in a storing part 7 via a distributing part 5. When all types of information are stored, an information arithmetic part 11 performs an operation of a parity check, etc. and stores th result of this operation at a preserving part 13. The result of operation stored at the part 13 is then transferred to the primary device through a transmitting part 9 and in the form of an answer 4. In case the subordinate device has a fault and the rise is given again to the subordinate device, the follower device sends an initialization request to the primary device. The primary device feeds the same information as the result of operation stored at the part 13 to the subordinate device. Then the follower device transfers this information only to a comparing part 16 from the part 5 via a bus 15. Thus a command 18 is delivered to start all functions of the subordinate device if the coincidence is confirmed at the part 16 between the information transferred to the part 16 and the information stored at the part 13.
