Title: Waveform memory
Inventor: HOSOKAWA NOBORU
IPC: G01R13/20
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To avoid reduction of memory capacity by half by controlling the order for outputting an A/D converted data thereby storing the A/D converted data uniformly in a polyphase memory. SOLUTION: A signal inputted to an A/D converter 1 outputs a data sampled from the data AD side at an A/D clock SC following to a falling and at an ADD clock SC preceding the falling. A control for shifting it by one clock at every decimation sample is performed using D flip-flops 7, 8 and a selector 9. The data of the data AD is stored at the rising of a memory signal AC generated tram a polyphase memory signal generator 6 and the data of next data BD is stored at the rising of a memory signal BC generated from the polyphase memory signal generator 6. A selector 9 shifts a data output control signal E of the A/D converter 1 by one or two blocks of the A/D clock for every rising of the memory rate signal DC of a waveform data and outputs a data to be stored alternately to the data A and the data B.

Filed: 1993-04-08
Abstract: PURPOSE:To enable a cooling apparatus to perform the cooling processing of food always in a clean condition by providing a bactericidal device which effects bactericidal radiation on the passage using a conveyor in the main apparatus. CONSTITUTION:After heat processing, food 8 is put into a frames body 1 through an entry 10 and passed inside a cooling chamber 16 of a jet cooling unit 3 successively. At this time a jet of cooling air ejected from a jet nozzle 19 destroys a layer of temperature boundary surrounding the food 8. The by directly cooling the surface the food 8 is cooled rapidly.

IPC: F02F1/10
Filed: 1979-08-23
Abstract: PURPOSE:To cool appropriately by a method wherein a capillary tube structure for replenishing the coolant is fitted around a heat source such as combustion chamber in order to cool the engine, and the surface area of the part where cooling is performed is changed. CONSTITUTION:A liquid coolant 9 is fed to and held at the entire outside wall of a combustion chamber and a cylinder by a capillary tube structure 3, and evaporates on receiving heat from the wall. The evaporated coolant passes through an evaporation chamber 2a and a passage 11 into a radiator 4, where it is cooled to condense by an electric fan 5, and the resulting liquid coolant is fed to the portion 1a where the capillary tube structure 3 is installed, to be reused for cooling. The portions where lubrication is required and the portions where thermal load is high are provided with a higher cooling capability by providing fins 12 and 12' at the desired portions of the outside walls of the cylinder and combustion chamber, whereas the wall surface of that portion of the combustion chamber corresponding to a quenching zone is provided with no fins so that a lower cooling effect is obtained there. Accordingly, appropriate cooling is achieved in accordance with each area.

Title: Machining device for bolt hole in flanged pipe
Inventor: UMEDA MIKIO
IPC: B23B41/00
Filed: 1985-05-20
Abstract: PURPOSE:To promote the improvement of productivity, by arranging a centering pin coaxially on an equal line with a drill and inserting the centering pin into a bolt hole in a flange in one side to be placed in the same phase with a bolt hole drilled in the other side. CONSTITUTION:A device, adapting an existing flange 2 to a thrust roller 10, positions a flanged pipe 5 in the direction of an axial center to be rotated about the axial center. A bolt hole 3 of the flange 2 is opposed to a centering pin 16 in a centering device 9. In this way, a phase of the flange 2 corresponds to the axial center of the pin 16 with the bolt hole 3 serving as the reference. Thus the machining device, causing also a drill 21 in a drilling device 20 to agree with the phase of the flange 2, machines a bolt hole to be aligned with the hole phase of the flange 2 in a cast flange 4.

Title: Large pneumatic tire of biased structure
Inventor: NAKAKURA KENJI
IPC: B60C9/06
Filed: 1981-07-09
Abstract: PURPOSE:To prevent the cord of the ply of a tire near its inside surface from being cut off due to the large deformation of the tire during its movement, by making the number of twists of the cords of inner plies larger than that of twists of the cords of intermediate plies. CONSTITUTION:The number of twists of cords constituting the inner plies 1a of a tire is made 1.1-1.5 time larger than that of twists of cords constituting the intermediate plies 1b, so that the cords are prevented from being cut off due to the repeated compressive strain of the carcass of the tire. The cord distance ratio of each of the inner and the outer plies 1a, 1c is made larger than that of the intermediate plies 1b to prevent separation from being caused by cracks which would occur on the twisted recesses of the surfaces of the cords and the corresponding boundary surface of rubber. The durability of the tire is thus heightened.

The mol.wt. of the high molecular nitrogen compd. as a gloss adjusting agent is controlled to 100-70,000. Polyethyleneimine, etc., are appropriately exemplified as the compd. The amt. of the compd. to be added is preferably adjusted to 0.1-200 ml/l. The glossiness is adjusted only by such an amt., the soln. temp. or other conditions need not be changed, and the glossiness is easily adjusted.

IPC: G05D1/02
Filed: 1995-05-02
Abstract: PURPOSE: To provide an improved method for searching a path in which a traveling path for allowing an autonomous moving unit to bypass an obstacle can be discovered. CONSTITUTION: A target direction is set at an autonomous moving unit SE, and the autonomous moving unit SE moves in the target direction until it collides with an obstacle H in the path, moves from the target direction to a first direction to bypass the obstacle in front of the obstacle, and travels further forward. When the autonomous moving unit can not bypass the obstacle until it reaches a prescribed first directional deflection limit, it returns to a starting point S after this erroneous trial. The autonomous moving unit returns to the starting point after the erroneous trial except that the autonomous moving unit starts from the starting point, and moves from the target direction to a second direction to bypass the obstacle.  After the two times of erroneous trial, the directional deflection limit is improved for searching a traveling path for allowing the autonomous moving unit to bypass the obstacle, and the directional deflection limit is improved until the autonomous moving unit can bypass the obstacle. After the autonomous moving unit bypasses the obstacle, the deflection from the target direction is returned, and the autonomous moving unit is allowed to travel further forward in the target direction.
