Title: Manufacture of travelling-wave tube device
Inventor: TAKEDA MITSUO
IPC: H01J25/34
Filed: 1985-12-18
Abstract: PURPOSE:To maintain high frequency action characteristic and lifetime characteristic favorably, by keeping a base plate in a higher temperature than its action average temperature, keeping the temperature of the cathode of an electron gun portion in a lower temperature than its action average temperature, and simultaneously adjusting a focusing magnetic field most suitably. CONSTITUTION:The electron beam focusing of a periodic magnetic field device 13 is carried out, in a condition that respective parts are assembled but a cover 16 is not mounted yet. In this case, a base plate 15 is kept in the almost highest temperature in a temperature in which a communication device using a travelling-wave tube is expected to encounter, for example, by a heater built-in device. On the other hand, the temperature of a cathode in an electron gun portion is set in a lower temperature than its average action temperature. The focusing condition of electron beams by the magnetic field device is adjusted most favorably, in a condition that the temperature of respective parts is stabled. Namely, a periodic magnetic field is adjusted minutely in such a manner that the quantity of the electron beams picked by a slow-wave circuit portion becomes lowest, and the magnetic field device is fixed in the most favorable condition.

Title: Ami signal polarity detector
Inventor: SAKANOBE KAZUNORI
IPC: H04L25/49
Filed: 1990-10-25
Abstract: PURPOSE:To make it possible to judge whether the polarity of an AMI signal is as set up or not using a simply constituted AMI signal polarity detector by proving the AMI signal polarity detector with a start bit polarity discriminating means of discriminating whether or not the polarity of the start bit of an AMI signal received based on the output from an AMI (Alternate Mark Inversion) polarity sign signal separating means and output from a start bit detecting means. CONSTITUTION:In response to a sign of the AMI signal, the input terminal RXD of communication control section 4-1 receives the AMI signal. Since the D input terminal of D type is already supplied with a high level signal from output terminal DPO of AMI polarity sign signal separating circuit 3a, Q output terminal of D type flip-flop is maintained as it is, and pilot lamp 10 holds lighting. If due to a certain reason the AMI signal is at the reverse polarity, the polarity of the state bit of start bit detecting sign signal separating circuit 3a becomes negative, and when receiving the start bit, the output terminal DPO of AMI polarity sign signal separating circuit 3a is set at low level, while the output terminal DMO is set at high level, thereby causing pilot lamp 10 not to light up.

IPC: H01J29/82
Filed: 1990-10-29
Abstract: PURPOSE:To prevent deterioration of picture quality by shielding the retaining parts for a cathode and convergence electrodes either electrostatically or optically viewed from the input side. CONSTITUTION:Retaining parts 9-11 for a cathode 3 and convergence electrodes 6--8 are arranged so that the electrode on higher potential side is overlapping the electrode on lower potential side while positioned inside thereof, wherein the higher potential the electrode has, the smaller has it the outside dia. to provide electrostatical shielding.

Title: Sheet feed mechanism for printer
Inventor: OKAMOTO FUMIAKI
IPC: B41J15/16
Filed: 1985-12-20
Abstract: PURPOSE:To eliminate a slack in a sheet to reduce noise and stabilize the position of printing, thereby reducing the load of a motor due to the inertia of a platen, by making the speed reduction ratio between the motor and the platen greater than that between the motor and a tractor. CONSTITUTION:The speed reduction ratio between a motor 1 and a platen 4 is made to be greater than that between the motor 1 and a tractor 7 by changing the sizes of platen and tractor pulleys 5, 9. Then, a torque transmitted from the motor 1 to the platen 4 allows the platen 4 to feed a printing sheet 10 upward under friction force since the sheet 10 is retained on the platen 4 by means of a paper guide 11. However, the rotational amount of the platen is less that that of the tractor 7, and therefore, the sheet 10 is always slightly stretched so that the printing is made in such a condition that the paper is sufficiently stretched at the printing position on the platen 4. Accordingly, a slack in the sheet 10 is eliminated to reduce noise and to stabilize the printing position, and due to the large speed reduction ratio, it is possible to greatly decrease the load of the motor due to inertia of the platen.
