Title: Seal device
Inventor: HARADA TERUMARU
IPC: F16J15/16
Filed: 1985-07-02
Abstract: PURPOSE:To enable a device to be sealed with no leak of gas, by forming spaces by flexible partitioning plates and side walls while hermetically sealing the space with fluid and preventing unreasonable force from acting on a diaphragm. CONSTITUTION:A device, forming fluid spaces 13, 14 by diaphragms 11, 12 and a cylinder 9, seals inside the spaces 13, 14 with fluid of oil or the like. The device, separating by pressure the fluid in said fluid space 13 from the fluid in the fluid space 14, enables the pressure of gas in space 16 to be almost equal to the pressure of the fluid in the fluid space 13. Consequently, unreasonable force is prevented from acting on the diaphragm 11, as the result, the device can be sealed with no leak of gas even if the gas of different kinds is used in the space 16 and space 17.

Title: Rotary anode x-ray tube
Inventor: HAYASHI TADASHI
IPC: H01J35/10
Filed: 1988-06-15
Abstract: PURPOSE:To prevent the deterioration of the voltage-withstanding property owing to the discharge between an anode and a metallic vacuum envelope by composing the structure and the size of the anode component opposite to the metallic vacuum envelope not to produce the deterioration of the voltage-withstanding property of an X-ray tube. CONSTITUTION:An anode rotary member 9 opposite to a shield tube 6a furnishes a support 11, a rotor lid 12, and a rotor driving member 13 in respect of the structure, and the length is determined to make the part opposing to the tube 6a in to the rotor lid 12 in order to reduce the burden of the weight to the bearing and to prevent the discharge. The border between the rotor lid 12 and the rotor driving member 13 is made at the size same as or larger than the size of the gap between the rotor lid 12 and the tube 6a. The lid 12 is made by using a high melting point of metal such as Mo, W, Re, Ta, or an alloy of them. As a result, even though a discharge is generated by the influence of minute projections or contaminations on the surface of the metal, when a high voltage is applied, the generation of metallic sputters from the anode side can be reduced to the minimum, and the condition to be the cause of the discharge can be purified by the formation. Consequently, a deterioration of the voltage-withstanding property is never generated.

Filed: 1993-06-17
Abstract: PURPOSE:To provide the transmitter for detecting a fault of a reception filter circuit and for giving an alarm to a host side by measuring a frequency characteristic of a built-in reception filter circuit with respect to an intelligent transmitter. CONSTITUTION:A transmission current with an accurate frequency is flowed through a load resistor 14 in a 2-wire loop to generate a reference voltage signal and an attenuation guantity caused by passing the signal through a reception filter 7 is compared with an attenuation in the case of a previously normal reception filter by a comparator 6, and when the both are coincident, it is detected by the generation of an interruption to a microcomputer 1. The frequency of the transmission current in this case indicates the frequency characteristic of the reception filter 7 and it is compared with a reference value and the presence and the absence of a fault is discriminated. Since the internal reception filter characteristic is independently diagnosed by the intelligent transmitter, the reliability is improved and the maintenance and management are facilitated.
