Title: Method and device for measuring bending of optical fiber preform
Inventor: NAGAE NOBUSADA
IPC: G01B5/20
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To easily judge whether an optical fiber preform is proper or not in its shape by quantitatively determining its bending. SOLUTION: Both edge parts of an optical fiber preform M are placed on each pair of rotary rollers 21 of a support means 2 and a position measuring equipment 3 is positioned at a starting position I and an ending position E along a guide axial body 41 by driving a motor 4. The boundary position of the optical fiber preform M in the sectional direction at both positions I and E is measured and the both boundary positions are equally divided into two portions by an operation processing means 6 to calculate each central point position. The length in axial direction between the positions I and E is calculated based on the amount of travel of the position measuring equipment 3 is calculated via an encoder 5 and a reference axial line is set by connecting both central points in the positions I and E.  Then, the position measuring equipment 3 is moved from the position I to the position E and the position of the central point is calculated for each measurement position with a specific pitch and then is plotted at rectangular coordinates (X coordinate surface) consisting of the reference axial line and the amount of deviation in diameter direction. By rotating and displacing the optical fiber base material by 90 degrees in peripheral direction and obtaining the amount of deviation in diameter direction as in the above, the amount of deviation is plotted on a Y-coordinate surface. Then, the amount of deviation between both coordinate surfaces is synthesized to obtain the synthesized amount of deviation.

When the received signal provided by the reception circuit 3 is normal and the reception level provided by the reception level detecting means 4 is higher than a preset reference value, transmission power is set to 5 mW.  Thus, the number of transmitters/receivers to be simultaneously used per unit time can be remarkably increased.

Abstract: PURPOSE: To minimize the discard loss portions after ingot making by letting a position reference be the corrected top surface of a large molding board at the time of automatically lowering a sleeve from a setting machine and inserting and setting the same into the mold in the large molding board on a truck.  
     CONSTITUTION: For example, the body length Ml of a round steel ingot M for wheels is beforehand calculated and this is beforehand inputted to an arithmetic circuit 10. Next, a detector 8 is turned and the distance L from the top surface of a large molding board 5 down to the bottom reference plane of an upper setting machine 1 is measured. If at this time there is mean flucturations in the thickness of the large molding board 5, the distance L fluctuates and if there are any local fluctuations, the L from the mean thickness position is measured, thus these have no relation with the overall length variations of a mold 3. The distance L is inputted to the circuit 10 which in turn operates L-l 1 =l 2 , outputs l 2 , inputs the same to the machine 11. The sleeve 2 is then lowered by the corresponding portion l 2  to automatically set the head part 4 in the specified position. Here, a pouring truck 6 is also beforehand held level by jacks.

Title: Supercritical refrigerating cycle
Inventor: YAMAGUCHI MOTOHIRO
IPC: F25B1/00
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in a refrigerating capacity when a rotational speed of a compressor is decelerated. SOLUTION: When a rotational speed of a compressor 1 is decelerated so that a pressure of a low pressure side becomes a prescribed value or more, an opening of a pressure control valve 3 is reduced to enhance an output side refrigerant pressure of a radiator 2 to higher than a prescribed pressure decided by an optimum control line ηmax, and the opening of the valve 5 is reduced to increase a heating degree to larger than a prescribed value. Thus, since a specific enthalpy difference of an evaporator 6 can be increased, even when the rotational speed to the compressor 1 is decelerated, it can prevent a refrigerating capacity from being largely lowered.
