Title: Method for measuring difference of beam path length
Inventor: NIIJIMA MASAYUKI
IPC: H04B10/032
Filed: 1986-02-21
Abstract: PURPOSE:To make it possible to accurately measure the difference of a desired beam path length, in measuring the difference between the length of two beam paths on the basis of the delay time of a pulse, by measuring said difference using at least two or more pulse cycles. CONSTITUTION:The pulse with frequency f1 repeatedly generated through a pulse generator 4 is inputted to a pulse monitor 6 through the route of electrooptical converter 3   beam splitter 2a   beam path 1b and the route of beam path 1d   beam splitter 2b   electrooptical converter 5 and pulse shift is observed by the pulse monitor 6. When pulse frequency is desired to be made high, the delay time Ti due to the difference between the beam path lengths becomes larger than a pulse cycle T and pulse cycle time Xn + delay time Ti (wherein n is natural number) becomes real time difference. Therefore, rough delay time difference is calculated on the basis of a low frequency pulse at first and accurate delay time difference is calculated subsequently on the basis of a high frequency pulse and, further, (n) is calculated from two data to measure the difference between the lengths of both beam paths 1b, 1d.

Title: Constant torque generator
Inventor: TENMIYOU MASAYUKI
IPC: H02P29/62
Filed: 1980-03-22
Abstract: PURPOSE:To exactly obtain a constant torque over a wide temperature range by providing a magnetic circuit section having a coil wherein the current of the coil is controlled in accordance with the temperature detecting signal at the vicinity of a rotating disc. CONSTITUTION:With a motor 11 rotating with a constant speed, magnetic circuit sections 15, 16 also rotate at the same speed. A magnetic flux is caused by a permanent magnet 18 so that a rotating disc 23 may cross a gap 19 and an eddy current is generated at the disc 23 by the rotation of the magnetic circuit section 15. As a result, the disc 23 receives a torque which is directly proportional to the rotary speed of a motor 11. The temperature at the vicinity of the disc 23 is detected to control the current of the coil 21 in the magnetic circuit section 16 in accordance with the deviation between a temperature detecting signal and a reference signal and variations caused by the temperatures at the generated torque is corrected. In this way, a constant torque will exactly be obtained over a wide temperature range.

Abstract: PURPOSE:To prevent the electrification of a sample, the splashing thereof by repulsion and the deterioration in quality, contamination, etc. by embedding the sample into a liquid metal or low melting metal having high purity and low vapor pressure and holding the same. CONSTITUTION:A small In lump 1a having 99.99% purity and 156 deg.C m.p. is melted by heating on a holder 2 consisting of SUS to form an In layer 1, then the holder 2 is cooled with air.

The sample 4 is loaded together with the holder 2 to the device and an ion beam 5 is irradiated to the sample 4 to analyze the elements thereof. An electric charge 6 generated on the sample surface conducts to the In layer 1 and therefore, there is no disturbance of the analysis by the electrification of the sample itself. The deformation of the sample shape is obviated according to the above-mentioned method and since the In has the high purity and low vapor pressure, impurities and released gases are hardly generated and the contamination of the sample and the device is obviated.

Abstract: PURPOSE:To obtain the superior vibrationproof effect for the vibration in the high frequency small amplitude outsides the vibration in the low frequency large amplitude, by setting the ratio between the sectional area and length of the gap between the flange part at the top edge of a member projecting from an inner cylinder and a fluid chamber wall surface in correspondence with the higher frequency. CONSTITUTION:When an inner cylinder metal fitting 10 and outer cylinder metal fitting 12 relatively shift in the eccentric direction, the incompressive fluid introduced in the first and second fluid chambers 38 and 40 is allowed to flow in the direction of the diameter of a mount through each opposed gap part 54, and the vibration input into the eccentric direction of the metal fittings 10 and 12 is prevented by the flow of the incompressive fluid in the gap parts 54 and 54. When the ratio between the sectional area to the length of each gap part 54 is set in correspondence with the relatively high equal frequency, and the incompressive fluid flows in the direction of the diameter of the mount through the gap parts 54 and 54, the secluded sound and the engine transmission sound, i.e. the vibration in the relatively high frequency region corresponding to the set frequency of the gap parts 54 and 54 can be prevented favourably, on the basis of the fluid action or the inertia mass effect of the incompressive fluid.

Title: Vp capacity controller and its method
Inventor: SAITO HIROSHI
IPC: H04L47/76
Filed: 1995-02-27
Abstract: PURPOSE: To distribute equipment capacity corresponding to communication service demand and traffic quantity at that time to a network and to efficiently operate the communication network by dynamically changing the band of VP in response to the use situation of VP. CONSTITUTION: A VP use rate, an overflow rate and a cell loss rate are calculated by the traffic of VP(virtual path) stored in a traffic quality data storage part 54 or quality measurement data. Data in the traffic quality data storage part 54 is always collected and accumulated from VCH or the like through a signal transmission/reception part. When data exceeds an increased installation threshold which is stored in a VP capacity calculation part 53 and which is previously decided, the increased installation of VP is judged to be required and the decreased installation of VP is judged to be required when data is less than a decreased installation threshold. When quality deterioration is not settled in spite of the increased installation of VP capacity, increased installation quantity is judged to the too small.  At the time of next increased installation, much more capacity is increasingly extended. Thus, increased/decreased installation quantity and necessity are learnt and next increased/decreased installation quantity is decided by using past increased/decreased installation history.
