Title: Reactor cooling system
Inventor: KITANO TAKAAKI
IPC: G21C15/12
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a reactor cooling system which can automatically control the temperature dropping rate of reactor water of a reactor, the temperature dropping rate of the top of a reactor pressure vessel, and the temperature difference between each section of the reactor when the core of the reactor is cooled at the time of shutting down the reactor.

Title: Vector correlation detecting circuit
Inventor: TOYOKURA MAKI
IPC: G06F17/16
Filed: 1989-09-27
Abstract: PURPOSE:To decrease the number of elements and to shorten the computing time by counting the negative subtraction results via a counter and obtaining the sum total of N pieces of data and the counter contents via an adder for calculation of the vector correlation value. CONSTITUTION:The subtraction (Xi - Yi) is carried out for each component to two N-dimensional vector data (X1, X2,...,XN) 11 and (Y1, Y2,...,YN) 12. When the subtraction result is positive, the subtraction (Xi - Yi) is kept as it is. When the subtraction result is negative, N pieces of data obtained as (Xi - Yi) via a bit inverting circuit 14 are added to the contents of a counter 16 that counted the negative subtraction results. Therefore just a single subtractor 13 suffices. Then an operation where the contents of the counter 16 are finally added can cover an operation where 1 is added to the inverted subtraction data when the result of the subtractor 13 is negative. As a result, the computing time is shortened for a simple vector correlation detecting circuit.

Title: Film photographing device
Inventor: TAGO AKIRA
IPC: G03B19/18
Filed: 1988-10-07
Abstract: PURPOSE:To prevent a rotary knob from being rotated during photography and to eliminate a defect in feeding a film when the rotary knob is rotated in the opposite direction by mistake by allowing the rotary knob to be rotated in the film feeding direction. CONSTITUTION:A clutch mechanism 15 which transmits the rotation of the rotary knob 13 to a crank part 11 and does not transmit the motion of the crank part 11 to the rotary knob 13 is provided between the rotary knob 13 and crank part 11. Therefore, when a clutch receiver 16 is rotated as shown by an arrow A by rotating the rotary knob 13, a crank shaft 11 couples with the internal diameter of a one-way clutch 15 and the turning force of the clutch receiver 16 is transmitted to the crank shaft 11. When the rotary knob is rotated in the opposite direction, a gap is formed between the internal diameter of the one-way clutch 15 and the crank shaft 11, so the turning force of the clutch receiver 16 is not transmitted to the crank shaft 11. Consequently, the rotary knob 13 is not rotated during photography and the rotary knob 13 is not rotated in the opposite direction by mistake, so that the leader part of a film is not disengaged from a take-up shaft.

Title: Decision for gloss of object surface
Inventor: ASANO YUICHIRO
IPC: G01N21/57
Filed: 1984-11-30
Abstract: PURPOSE:To enable decision on the gloss quantitatively in a wide coarse range while making the decision match closer with the visual gloss about objects of the same color, by setting the wavelength and the incident angle so that the dispersion satisfies a specified formula in the height distribution of the surface profile to be measured to detect the intensities of direct reflection and the intensities of total reflection of two luminous fluxes projected. CONSTITUTION:For example, the wavelengths lambda1 and lambda2 and incident angles theta1 and theta2 are set so that the dispersion sigma satisfiers the relationship of the formula in the height distribution of the surface profile of an object to be measured such as stainless steel plate and two luminous fluxes with the wavelengths lambda1 and lambda2 are projected to the surface of the object being measured at the incident angles theta1 and theta2 to detect the intensities I1 and I2 of direct reflection and the intensities S1 and S2 of total reflec tion thereof respectively. Then, representative points of individual visual glosses are plotted on 2-d planes (I1/S1, I2/S2) beforehand and connected together smoothly to determine the curve l. Based on the straight line (m) perpendicular to the curve l, the gloss of the desired object being measured is disciminated. Thus, the gloss can be quantitatively decided on in a wide coarse range thereby permitting the measure ment and management of the surface quality online.
