IPC: H01J49/40
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a TOFMS capable of large-dynamic range measurement by use of a small-dynamic range high-speed measurement system. SOLUTION: This spectrometer has a high-speed preamplifier 5 which allows changing in multi-stage an amplifying factor between an ion detector 3 and a measurement system 4. When an ion pulse occurs, the amplifying factor of the high-speed preamplifier 5 is changed over to measure mass spectra at various amplifying factors. A gain of the mass spectrum is calibrated with the amplifying factor in the measurement, then a mass spectrum measured at a low amplifying factor is adopted in a position where an ion intensity is strong, while a mass spectrum measured at a high amplifying factor is adopted in a position where the ion intensity is weak. Thereby, a series of mass spectrum is composed.

Title: Current lead for superconductive equipment
Inventor: YAMAMOTO YUICHI
IPC: H01F6/00
Filed: 1986-05-13
Abstract: PURPOSE:To decrease an amount of heat penerating into a superconductive equipment by arranging a current lead of a spirally wound conductor in an insulated cylinder, or to hold a predetermined shape of the conductor by winding the conductor spirally on the external periphery of a core which is received in the insulated cylinder. CONSTITUTION:In one embodiment of a current lead L1, a cooling medium produced in a cyrogenic container 1 is guided to inside of an insulated cylinder 4 from the lower open end thereof and raises up in the cylinder while absorbing heat conducted from a constant- temperature section and Joule heat generated by current, from a spirally wound conductor 8a. The cooling medium is then dishcarged from the cylinder through an outlet 10. The length of the conductor is thus increased by winding the same spirally and, therefore, an amount of heat penetrating into a superconducting equipment disposed in the container 1 can be decreased. Further, since the surface area of the conductor 8a is also increased, a sufficient cooling effect can be expected. In another embodiment of a current lead L2, a cylindrical core 12 is arranged coaxially within the insulated cylinder 4 and is supported at the lower end 13 of the insulated cylinder 4 inserted into the cyrogenic container 1. The core 12 is a pipe having a low heat conductivity and the ends of the pipe are closed by caps 12a. A conductor 12 is wound spirally on the external periphery of the core 12 and connected to the superconducting equiment within the container 1 through a terminal 7a and a lead 9. The spiral form of the conductor is held in this manner and an efficient cooling effect can be obtained.

IPC: H03L7/181
Filed: 1985-05-20
Abstract: PURPOSE:To stabilize the frequency by providing a temperature detector, a storage device, a CPU and a synthesizer supplying a control signal to an oscillator together with other control signal. CONSTITUTION:The temperature detector 1 detects the ambient temperature of the oscillator, an analog digital converter 2 converts the output into a digital signal and gives the signal to the CPU 3. The frequency temperature characteristic of a piezoelectric oscillator and a frequency change versus control voltage change of the oscillator 7 are stored in advance in the storage device, the CPU 3 generates a frequency control signal of the oscillator based on the storage data information, the signals are converted into analog quantities by a digital- analog converter 5 and the result is fed to the oscillator 7 via the synthesizer 6. On the other hand, the change in the lapse of time in the frequency is processed by the count of the operating time of the oscillator and the data of the frequency change time characteristic and a time count circuit 8 integrates the operating time by counting the oscillated wave of the oscillator 7. The synthesizer 6 synthesizes the control voltage signals to the temperature change and change in the lapse of time fed to the oscillator 7 so as to compensate the frequency change due to various causes to the oscillator.

Title: Reproducing device of information disc
Inventor: SAKAI KIYOHARU
IPC: G11B17/049
Filed: 1982-06-24
Abstract: PURPOSE:To ascend a disc smoothly at the lifting of the disc by forming a connecting path to connect a closed space with the external on the external circumference part of a turn table. CONSTITUTION:A hole 33 is formed at a position close to a projected part on a table surface part 8c of the turn table 8. Since the hole 33 is formed on the external circumference part of the turn table 8, the flow rate of air near the hole 33 reaches approximately the maximum when the turn table 8 is rotated and the air pressure reaches almost the same negative pressure as the one generated in the closed space 30, so that the inflow of air is scarcely generated. Therefore, the negative pressure for the prevention of surface vibration or the like can be kept as it is at the rotation of the disc. At the lift of the disc, air is made flow from the hole 33 into the closed space 30 and the disc 1 can be smoothly lifted. Consequently, surface vibration at the rotation can be prevented and the disc can be smoothly lifted without any interference at the lifting.
