Title: Piston pin used in mg alloy piston
Inventor: UCHIDA KAZUHITO
IPC: F16J1/16
Filed: 1984-06-11
Abstract: PURPOSE:To improve rigidity, lessen abrasion and reduce a piston pin in size by using a solid state piston pin made of silicon nitride in an Mg alloy piston in an internal-combustion engine. CONSTITUTION:In a piston 1, a piston pin 2 made of silicon nitride is used. With the piston pin 2 made of silicon nitride, Young's modulus is raised, and bending deformation of the pin is decreased, and a single contact with a pin boss hole 4 and the axial relative sliding are reduced. Thus, abrasion of a pin boss is decreased. That is, if the bending deformation of the pin 2 is decreased, a contact portion of the outer periphery of the pin 2 with the inner periphery of the hole 4 of the piston pin boss 3 is kept from being single-sided, and the axial sliding indicated by an arrow (a) of the pin 2 is decreased, so that abrasion of the hole 4 of the piston pin boss 3 is lessened.

Title: Method and equipment for stabilization of oscillation frequency of semiconductor laser
Inventor: SUYAMA MASUO
IPC: H01S5/0687
Filed: 1988-05-19
Abstract: PURPOSE:To lift restrictions on the number of channels to be multiplied and to set the frequency interval between channels at a desired value by controlling the oscillation frequency of a first semiconductor laser so that the frequency of a beat signal obtained through detection of a mixture of the output light of the first semiconductor laser and the output light of a reference laser by a first light detector. CONSTITUTION:The output light of a reference laser 1, the oscillation frequency of which is absolutely stabilized, is mixed with the output light of a first LD2-1 by means of an optical mixer 5-1 such as a directional coupler. The mixed light is detected by a light detector 3-1 such as an APD. At this time, a beat signal, which has the difference of frequency between the reference laser 1 and the first LD2-1, is generated in the detected output of the light detector 3-1. By feeding back a driving parameter of an LD2-n in the nth place by an AFC circuit 4-n so as to keep the frequency of the beat signal constant, the oscillation frequency can be relatively stabilized against an LD in the (n-1)th place. As a result, the oscillation frequency can be relatively stabilized against the reference laser.

Title: Evaluating method of degree of saccharinity of fruit
Inventor: KIMURA NORIYUKI
IPC: A23N15/00
Filed: 1995-05-19
Abstract: PURPOSE: To evaluate the degree of saccharinity of a fruit in a nondestructive manner and quickly by measuring longitudinal and lateral relaxation time of a nucleus of hydrogen in a water molecule contained in fruit juice. CONSTITUTION: When a watermelon 15 is put in the center of a bore of a main coil 1, that is, in a static magnetic field in the direction of the axis (z), a magnetic field moment of a spin of a nucleus of hydrogen of fruit juice precesses around an axis parallel to the axis (z). While a gradient magnetic field is impressed 2 in the direction of the axis (z), a selective 90-degree pulse is impressed by a probe coil 3 and a slice area in the direction of the axis (z) is limited. Then only the spin in a specific slice plane intersecting the axis (z) perpendicularly changes direction at an angle of 90 degrees. When a time Te of impression passes after the same operation is executed also in the directions of the axes (x) and (y), an echo signal is obtained.  The echo signal observed from outside is only the one from an area wherein three orthogonal slices overlap one another, and by executing slice selection so that this area may coincide with the area wherein the degree of saccharinity is to be evaluated, evaluation for the specified area can be performed. Accordingly, the central area of 10×10×10(mm) is selected and longitudinal and lateral relaxation time T1 and T2 are measured from the echo signals obtained with the time Te varied.
