Title: Light output monitoring system for light repeater
Inventor: WAKABAYASHI HIROHARU
IPC: H04B17/00
Filed: 1979-05-17
Abstract: PURPOSE: To accurately measure the quantity of the fall in the laser output of a repeater, under remote control from a landing station, by using a reference DC voltage and a simple comparision circuit in submarine light repeating system.  
     CONSTITUTION: A leser unit 6 is driven by the sum of a bias direct current supplied from an ALC circuit 13 and a signal current supplied from a driver circuit 11. The output light of the laser unit is transmitted to optical fibers 4 and introduced into a monitor circuit 14 through a light-electricity converter 12 and a filter 52. The outputs of the filter 52 and a reference voltage generator 71 are compared with each other at 72 in the monitor circuit 14. An output as a result of the comparison is applied to a terminal station unit through an optical fiber circuit. The mark rate of a testing signal sent out by the terminal station unit is changed to such a value that the comparion circuit 72 generates an output. The quantity of the fall in the light output of a light repeater is measured in terms of the quantity of the change in the mark rate to said value.

Title: Boring method for ceramic molded material
Inventor: KAWASAKI KIYONOBU
IPC: B28B11/12
Filed: 1989-03-14
Abstract: PURPOSE:To bore in a short time without generating chippings or cracks on a ceramic molded material by using a two-straight-edge end mill cutter. CONSTITUTION:A straight edge and mill cutter is put through a boring site of a ceramic molded material, and then finishing process is started immediately. Chippings are never generated in inlet and outlet sides of the end mill cutter for boring of the ceramic molded material by using the straight edge and mill cutter, even it a cut surface is an inclined curved surface or the wall thickness is different. Further, boring can be carried out in a short time in two processes, boring through and finishing, which generates little wearing of a cutter, and as the cutter is of straight shape, the correction of the edge can be carried out easily to make the life very long. In this case, the cutter with two edges is most remarkably effective.

Title: Taste analyzer for rice
Inventor: KAMIYA KOSEN
IPC: G01N21/359
Filed: 1993-03-19
Abstract: PURPOSE:To make calculation of accurate taste evaluation value possible calculating a taste evaluation value from a taste influence component value and correcting the calculated taste evaluation value while substituting a predetermined whiteness for a detected whiteness. CONSTITUTION:Whiteness of sample grains (unpolished rice or polished rice) is detected using a whiteness detecting means, i.e., an analyzer (means for detecting absorbance by irradiating a sample with near infrared radiation), or whiteness gauge and a final whiteness is calculated according to a whiteness working curve. A taste influence component calculating means calculates the contents of protein and amylose in sample grains for which the whiteness value is calculated according to the working curve. A taste evaluation calculating means then calculates a taste evaluation value based on the contents thus calculated. When the whiteness thus calculated is other than 40%, for example, whiteness of 40% is substituted for it and correcting means corrects the taste evaluation value and presents a corrected taste evaluation value on a display means.

Title: Flywheel
Inventor: OGAWA KAZUFUMI
IPC: F16F15/31
Filed: 1983-04-06
Abstract: PURPOSE:To save energy at the time of a start-up or acceleration from a low rotational speed by filling approximately half a volume of a cavity in a wheel as a flywheel with liquid etc. and displacing its center of gravity in response to the rotational movement. CONSTITUTION:A flywheel 1 has in its wheel 2 multiple cavities 3 symmetrically relative to the center of a rotary shaft 5. The cavities include the rotary shaft in their axial direction, and have in their interior equal amount of weights 4a-4d for displacing the center of gravity. At the time of an engine start-up or a low speed operation, the weights 4a-4d move spontaneously due to the gravity in response to the rotational angle in the cavities 3 for displacing the center of gravity of the wheel. When tilted several degrees to the right, a liquid weight 4a in the cavity 3 moves outwardly and the liquid 4c inwardly, and so the center of gravity of the flywheel 1 moves from point A to point B to generate a right-hand torque. In this manner, the flywheel rotates continuously with an input of energy only in a small amount.
