Abstract: PURPOSE:To enable the smooth and light drawing-out of filter paper, by certainly separating filter paper from spikes. CONSTITUTION:When a motor 7 is driven, an endless chain 6, an upper chain 10 and a lower chain 11 moves to a clockwise direction in a circulatory manner and an upper parallel shaft 2 and a lower parallel shaft 3 are rotated to a clockwise direction. Whereupon, left and right movable upright members 12 repeat motion such that they are parallelly moved to the right from the position of a drawing and subsequently moved downwardly along a semi-circle to be moved to the left over a distance L and moved upwardly along a semi-circle to be moved to the right. Therefore, a spike bar 15 is upwardly moved when the upright members 12 are moved upwardly but filter paper FP is pressed to a filter paper tray P during a stroke H by a filter paper presser 19 and spikes 16 are perfectly pulled off from the filter paper during this time.

Title: Fuel correcting unit of fuel injection type internal combustion engine
Inventor: AOI TOMIO
IPC: F02D41/10
Filed: 1981-03-25
Abstract: PURPOSE:To improve the performance of acceleration preventing a plug from wetting or ignition failure by arranging a unit prohibiting fuel additional jetting when increase rate of opening degree of throttle valve doesn't continue more than the expected time in the range of specific value. CONSTITUTION:When increase rate DELTAthetath/DELTAt of opening degree of throttle valve is in an accelerating condition exceeding the reference value B and signal K is outputted from a comparator 17, a flip-flop 18 is set to practice a momentary acceleration of fuel. As the engine transfers from its accelrating condition to its cruise condition, a pre-set counter 41 begins counting of rotation speed Ne. At this time the counter 41 doesn't generate output, signal K1 can't set the flip- flop 18, and a momentary additional calculation at the time of acceleration of fuel is prohibited. Thus wetting of plug and ignition failure based thereupon is prevented to improve performance of acceleration.

Filed: 1990-02-26
Abstract: PURPOSE:To preclude a breakage accident due to freezing by providing a means which uses the signal of a temperature sensor not only for the temperature influence correction of a pressure sensor, but also to calculate a temperature value positively. CONSTITUTION:The outputs of the pressure and temperature sensors are inputted and the temperature value is calculated by using the temperature sensor output which is used only for the temperature influence value correction of the pressure sensor.

Abstract: PURPOSE:To enable the formation of semiconductor crystals of excellent quality on an insulating layer by a method wherein a polycrystalline or amorphous semiconductor layer is formed on a single-crystal semiconductor with an amorphous insulating layer interposed between them and with part of the semiconductor layer made to contact with a substrate, and then electron beams are applied thereto for annealing through a covering layer having irregularity. CONSTITUTION:A buried SiO2 layer (first insulating layer) 12 is formed selectively on a single-crystal silicon substrate 11 of P-type (100) face orientation. Next, a polycrystalline silicon layer 13 is formed on the whole surface and an SiO2 film 14 (second insulating film) is deposited thereon. Then, a resist pattern 15, which has indentation to be formed in the ground SiO2 film 14 by a photoengraving process, is formed, and the SiO2 film 14 is etched with the resist pattern 15 used as a mask, so as to form a grating whose surface has regular indentation.

Filed: 1978-04-14
Abstract: PURPOSE: To give a continuous and comfortable field of view from far to near vision to the person whose crystalline lens has decreased in control power by so forming the lens that the group of intersecting lines that the plane rectangular to the main meridian assumes becomes smaller in curvature on the lower side and larger on the upper side.  
     CONSTITUTION: The lens is divided to a far vision part F, progressive focus part P and near vision part N along the main meridian MM' and the circular intersecting line composed of the face crossing the line MM' at a right angle and refractive face exists at the point A. The circular intersecting lines are at the top end of the region P or above this to enable a wide field of view to be obtained from the point P up to the region N. The curvature of the group of intersecting lines perpendicular to the line MM' in the region P and region N becomes smaller as it goes further from the line MM', thus enabling the astigmatism and distortion aberrations around the lens to be minimized. In the region F, the curvature of the group of intersecting lines becomes larger as it goes further from the line MM' and therefore the balance of the distortion aberrations of the entire part of entire part of the lens may be improved.
