Title: Contact type spiral spring
Inventor: KOJIMA ITSUO
IPC: F16F6/00
Filed: 1989-06-21
Abstract: PURPOSE:To stabilize noncontacting parts for preventing the occurrence of vibration by magnetizing thin-band shaped spring materials in the width or thickness direction, so that either of both ends of the spring materials in the width direction has the same polarity so as to mutually repel and restrain, while on the other hand, the contacting surfaces of adjacent spring materials have different polarity so at to mutually attract and restrain. CONSTITUTION:On the other circumferential surface of a cover 3 on one side, a ring- shaped permanent magnet 8 the inside of which contacting with the cover 3 has the N-pole, while the outside has the S-pole is provided, and on the outer surface of a cover 4 on the other side, a ring-shaped permanent magnet 9 the inside of which contacting with the cover 4 has the S-pole, while the outside has the N-pole are provided; and they are concentrically fixed respectively. Thereby, in the spring materials 6, S-pole and N-pole are induced at the ends on the cover 3 side, and at the ends on the cover 4 side respectively, so as to be magnetized in the width direction, and either of both ends of the adjacent spring materials 6 has the same polarity, so that a mutually repelling force is produced. Thus, since the spring materials in a spiral spring 5 push to each other so as to be retrained, they are brought in a stable condition, and the occurrence of pulsation in the torque/turn curve or collision noise due to vibration can be prevented.

Abstract: PURPOSE:To judge the time of completing evaporation of a reducing agent solution from a change in output of temperature in a vent pipe connected to a reaction vessel and advantageously obtain the objective compound in a short time by sensing the aforementioned temperature in synthesizing the subject compound from gaseous carbon dioxide labeled with <11>C. CONSTITUTION:<11>CH3I useful as a labeling compound for a position emission tomography (PET) system used in a position tomographic testing method is synthesized by a step for producing <11>CO2 gas labeled with <11>C in a target box 4, a step for bubbling the produced <11>CO2 gas into a reducing agent solution in a reaction vessel 14, a step for evaporating and removing the reducing agent solution after completing the bubbling and a step for synthesizing the <11>CH3I from an intermediate reduced in the bubbling step. In the process, temperature in a vent pipe 15 connected to the reaction vessel 14 is sensed with a temperature sensor 21 to judge the time of completing evaporation of the reducing agent solution from a change (b) in output thereof. Thereby, the reducing agent solution is completely evaporated under any conditions to reduce danger of failure in synthesis. The synthesis time of the <11>CH3I is simultaneously shortened.

Abstract: PURPOSE:To obtain a high pressure discharge lamp having a simple restarting circuit built-in an outer tube as well as an instantaneous restarting function by sealing gas of more than one kind of xenon, krypton, argon, neon, helium, nitrogen and mercury having specific pressure into an outer tube. CONSTITUTION:When a power supply is directly connected to a lamp base 8, firstly a current flows through the stabilizer 16 of a filament 14a due to discharge between the contact of a thermal response element 15. After the contact of the thermal response element 15 is closed, said contact is reopened to cut off the current, surge voltage is generated while said voltage is impressed between both main electrodes 2a and 2b to start discharge between the main electrodes 2a and 2b thus to complete the starting. The pressure of the gas sealed in the outer tube 13 is required to be controlled to 10<-4>-20 (Torr). When the pressure surpasses 20 (Torr), the surge voltage drops remarkably so that the lamp does not start. Also, when the pressure drops below 10<-4> (Torr), a circuit dielectric breakdown occurs thus disabling to use the lamp.
