Title: Water droplet detector
Inventor: TANAKA HIKARI
IPC: G01N21/41
Filed: 1987-07-13
Abstract: PURPOSE:To enable detection of adhesion of a water droplet accurately even in rain almost as fine as drizzle, by forming a mass of water droplets on the surface of a light transmitting member to flow out in a relatively large water droplet. CONSTITUTION:A water detector 5 is mounted in such a form as to extend roughly to top and bottom along the back of a door mirror 4. When a water droplet (d) adheres to a contact surface between a light transmitting member 6 and the atmosphere, namely, a water droplet detection surface 60, light beam leaks out through an adhesion surface and an output of a light receiving element 8 decreases in proportion to an adherence of the water droplet (d) thereby allowing detection of the adhesion of the water droplet (d). The light transmitting member 6 is provided with a water droplet outflow means 9 comprising a projection on the surface thereof near the light receiving element 8. The means 9 serves as a weir and, for example, when rain is a drizzle or so, it is stemmed by the means 9 and when running over the means 9, a mass of water droplets built up falls growing of a relatively large water droplet d'. Light leaks out at a part to which the water droplet d' adheres and the adhesion of water droplets is judged by a decrease in the quantity of light received with the light receiv ing element 8.

Title: Circuit, method and system for arithmetic processing
Inventor: STEELE GUY L JR
IPC: G06F7/552
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To accelerate arithmetic processing based on an SRT algorithm to be used for the division of integers or decimal numbers and the operation of square root, by estimating the numeral of the quotient in an entire clock cycle. SOLUTION: The circuit 500 estimates following quotient numerals while previously having enough time margins so as to arrange a quotient numeral selection path 510 outside a critical path. When a partial remainder PRi is inputted, the circuit 500 initializes the estimating processing of the quotient numeral for selecting a partial remainder PRi+5 based on 31 pieces of quotient selector circuits 515. Thus, the data of the quotient selection path 510 meet multiplexer layer (five layers of 520a-520d and 540) almost as many as the data of a 1st partial remainder data path 520 (five layers of 530a-530d and 540). As a result, the quotient numeral is selected only by executing addition four times and CSA delay is suppressed into level 3.

Filed: 1984-08-21
Abstract: PURPOSE:To obtain a product having high accuracy at a low cost by executing continuously and integrally respective stages for shot blasting, rolling and finishing and further shearing of a metallic sheet in synchronization with the flow of operations. CONSTITUTION:The metallic sheet 1 is nipped by rolls 3 and is fed to a blast room by the revolution of the rollers 3' in the 1st stage A. Shot 6 is struck against the metallic sheet by impellers 5 to descale the sheet and air is blown to the sheet 1 by a dust remover 7 to remove the dust sticking to said metal; at the same time the rollers 3' are revolved to move the sheet to the succeeding stage. The sheet 1 is rolled at a low draft by rolls 8 and the surface roughened by the shot blasting is smoothed by said rolls in the 2nd stage B. The sheet is then moved to the succeeding stage by the revolution of the rolls 8. The metallic sheet is passed through a slitter 9 and is thereby cut to a prescribed width; further the sheet is nipped by tension pads 10 and is deflected by which the modulated flow of the line is corrected in the 3rd stage C. The sheet is thereafter sheared by a shear 11 and is coiled on a recoiler 12.

Then, a body to be tested is placed on a fall test table, which is fallen naturally to pass a rod through a rod passing board 1b and make it strike on the piston 2. A shock is generated when the rod strikes on the piston 2 and transmitted to the body to be tested through the rod and fall test table and thus applied to the body to be tested.

Filed: 1989-07-06
Abstract: PURPOSE:To initialize an internal register to an arbitrary value at high speed when performing reset without adding hardware of large scale by reading initialization data from an external bus by separating from another interruption when performing the reset, and initializing the internal registers more than that in ordinary interruption. CONSTITUTION:A central arithmetic processing unit is mainly separated to an instruction control part 11 and an arithmetic part 12, and is provided with plural interruption sources.
