Title: Vertical laser diffraction type particle size distribution measuring device
Inventor: SHIMAOKA HARUO
IPC: G01N15/02
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To secure a side scattering light and measure even fine particles of a sample even when the thickness of a sample layer is small. SOLUTION: A laser light emitting from a laser light source 1 is changed into a parallel flux with a specified cross section through a collimator 2, and it is directed to an open type cell 3, then it is scattered or diffracted through sample particles in a cell 3. The diffracted/scattered light is formed as a diffracted/scattered picture on the light receiving surface of a forward diffracted/scattered light sensor 5 through a condenser 4. In addition, the intensity of a scattered light with a large scattering angle is measured by a side scattered light sensor 6 or backward scattered light sensor 7. These data are calculated in the specified algorithm by a computer 8 and the particle size distribution of sample particles can be obtained.  Since a laser light axis is allowed to tilt by a specified angle from the vertical direction, the side scattered light can be secured even in a thin sample layer, permitting the measurement of particle size distribution.

Abstract: PURPOSE:To ensure that the initial manual formation of a paper-joining tube can be achieved even by a non-experienced person and thereby wasteful consumption of paper material can be minimized by allowing a cylindrical fixture with a connection part to the tip of each paper material to be engaged with a mandrel previously in accordance with a positional relationship in which each paper material for continuous formation of a paper-joining tube is wound around and laminated on a cylindrical part with the same inner and outer diameters as the paper-joining tube to be formed, and initiating formation of the paper-joining after connection of the tip of the paper material to each connection part. CONSTITUTION:A fixture 10 is engaged with a mandrel and a belt is wound around a cylindrical part 10a. Next the tips of paper materials 12a to 12g corresponding to each of connection parts 13a to 13g are drawn out of a feed device and connected in such a manner that an adhesive is applied to a spot slightly after the tip and then the rest.

Title: Temperature compensated crystal oscillator

Abstract: PURPOSE:To flatten a compensation temperature characteristic by giving linearity to the respective frequency-temperature characteristics of the first and second oscillating circuits within a standard temperature range and specifying the respective frequency temperature gradients of the first and second oscillating circuits and the respective oscillating frequencies of the first and second oscillating circuits at the time of a reference temperature. CONSTITUTION:When a room temperature t0 changes for DELTAt1 deg.C an oscillating frequency fa1 of the first oscillating circuit 6 heightens (lowers) from its reference frequency fa0 with a variation DELTAfa accordant with a frequency temperature gradient DELTAAppm/ deg.C and becomes f1+fa0(DELTAA.fa0.DELTAt1)MHz. On the other hand, an oscillating frequency fb1 of the second oscillating circuit 7 heightens (lowers) from its reference frequency fb0 with a variation DELTAfb accordant with a frequency temperature gradient DELTABppm/ deg.C and becomes fb0+DELTAfb(DELTAB.fb0.DELTAt1)MHz. Consequently, a difference frequency DELTAF1, which is to be an output from a mixer 8, becomes fa-fb+(DELTAA.fa0-DELTAB.fb0)DELTAt1. Further, when the variations DELTAfa and DELTAfb of the first and second oscillating circuits 6 and 7 caused by a temperature are made constant (namely, fa0:fb0=DELTAB:DELTAA), the difference frequency DELTAF1 at the time of the DELTAt1 can be made into fa-fb. Thus, the flat compensation temperature characteristics can be obtained.
