Title: Fuel controller for diesel engine
Inventor: KONDOU JIYUNICHI
IPC: F02D41/38
Filed: 1980-05-31
Abstract: PURPOSE:To perform perfect combustion of an engine and prevent occurence of its black smoke, by controlling a fuel injection pump in accordance with a result of comparing the amount of fuel required for the perfect combustion at detected speed of the engine with the amount of fuel corresponding to preset speed of the engine from a control handle. CONSTITUTION:To detect rotary speed of an engine 3, a speed detector 2 is provided in the vicinity of a flywheel 9 and its output signal is input to a perfect combustion fuel amount calculator 4. The calculator 4 calculates the amount of fuel capable of perfect combustion at input speed to output a fuel actuator position R* corresponding to said amount of fuel. While a handle setting fuel amount calculator 5 calculates a difference between preset engine speed with a control handle 1 and detected engine speed and calculates the fuel amount for said difference to become minimum to output a fuel actuator position R. These positions R*, R are compared by a comparator 6, thus the injection amount of a fuel injection pump 8 is controlled by said compared result through a fuel actuator 7.

Title: Brake friction material
Inventor: MIYAKE SHINGO
IPC: C08J5/14
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To obtain a brake friction material having improved mechanical strengths without detriment to other performances by incorporating a silane- group-contg. crosslinked polyolefin into a brake friction material comprising a fiber material, a lubricant, a friction modifier, a filler, a binder, etc. SOLUTION: The content of the crosslinked polyolefin is pref. 1-10 wt.%, because the content in this range can maintain excellent shear strength and friction properties. The silane groups of the crosslinked polyolefin form crosslinks with the polyolefin itself by water, increasing the crosslink density of the crosslinked polyolefin; and silane groups extending from the matrix of the polyolefin condense with Si groups of other ingredients constituting the brake friction material, forming crosslink structures between the polyolefin and the other ingredients. Three-dimensionally crosslinked polyethylene or polypropylene is used as the crosslinked polyolefin.

Abstract: PURPOSE:To achieve scintigram photography with optimum photographic density by previously measuring the beam intenity of a CRT display device, i.e. brightness during unblanking, and then controlling the total amount of emitted light of the CRT during the scintigram photography according to said measured value. CONSTITUTION:A light emission image on a CRT display device 1 is guided through a lens 8 to a film 9, thus performing scintigram photography. At this time, part of the output image luminous flux of the display device 1 is branched by a half-mirror 10 at a prescribed ratio, and then condensed and caused to strike a photodetecting element 13. The output of the element 13 is supplied to an integrating amplifier 21, which performs time integration to output a voltage which corresponds to the total amount of light of the light emission image incident to the film 9. This output voltage is compared by a comparator 22 with a voltage which corresponds to the beam intensity of the display device 1, i.e. a voltage held by a voltage holder 20; when the former becomes higher than the latter, a signal is supplied to a gate 23, which is closed to intercept a brightness into to the display device 1, stopping the light emission of the display device 1. In this case, gains, etc., of amplifiers 19 and 21 are so set that photographic density providing adequate light and shade is obtained.

Abstract: PURPOSE:To satisfactorily execute a thickening processing and to improve the accuracy of decision by tracing a contour according to the thickening processing of a handwritten character pattern, detecting four close white points by the shift processing of a contour point and deleting the white point of the contour point in the same direction as a shift direction. CONSTITUTION:The feature vector of a character pattern 1 is extracted by a feature extraction part 2 and matched with a dictionary by a decision part 3. When this vector is rejected by a reject decision part 4 while maintaining a large distance value in any category, the patterns before and after the shift processing of a character pattern shift part 5 are processed by an OR pattern generation part 6. Thus, the pattern is made easy to be decided by receiving the thickening processing, and the contour is traced by a character contour trace part 17. Then, the four close white points on the up, down right and left sides of the traced contour point are detected by a four- close white point detection part 8, and the contour point equipped with the white point in the same direction as the white point detection time is erased by a contour point erasing part 9. Therefore, the thickening processing is satisfactorily executed and the accuracy is improved for deciding the handwritten character such as O or U, etc.

Therefore, a part of reformation rollers 10, 10 is extruded into the passing route 6 by the rotation of the screw 16 and it is fine-adjusted so that it is located for bending at a right angle the lead terminals 18, 18. When the accommodation case 4 is sent into the passing route 6 while it is reversed and said accommodation case 4 is further pushed, the side plates 5, 5 advances rotating the guide rollers 9, 9. The accommodation case 4 having passed the reformation rollers 10, 10 enters into the passing route 6 of the block 3 in the rear side through the guide rollers 9', 9'. At this time, since the accommodation case 4 is made of elastic material, it is recovered to the original shape and only the lead terminal 18 is left being reformed at a right angle.
