Title: Pattern machining process for surface of stone material
Inventor: WATANABE TOORU
IPC: B28D1/30
Filed: 1980-07-15
Abstract: PURPOSE: To provide a simple and fast making or low convex or concave pattern by a method wherein some small iron steel pieces are projected continuously or intermittently by a centrifugal projecting device onto a surface of the natural stone.  
     CONSTITUTION: Stone material 1 to be worked is transported by a belt conveyor 3. Small pieces of iron steel 4 are projected from the projection machine 5 onto a surface of the stone material to be worked, and then a pattern is formed on a surface of the stone material by the shock force of the small iron steel pieces. Small pieces of iron steel 4 projected onto the stone material are recovered and used again in a repetitive manner. Some fine dusts generated from the stone material are separated from the small pieces and removed by a proper process. The stone material may be transported by a rotary table other than a belt conveyor.

Title: Position grasping method of wafer, and exposing method and exposing device thereof
Inventor: UEDA TAKUSHI
IPC: G01B11/00
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To satisfactorily process the unclear circumferential edge image of a low wafer by taking images of a plurality of edges, determining the approximate expression of the edge within the image or the coordinate in a prescribed point on the approximate expression by image processing, and expressing the wafer circumferential part by a numerical expression. SOLUTION: An image processing means 106 has a binarized level setting means, a profile tracking means or the like. The average luminance within a threshold determining area is calculated by the binarized level setting means. The value obtained by multiplying the average luminance by a constant is taken as the initial threshold. In the profile tracking means, the edge detecting area is scanned from the upper right to the left by use of the initial threshold. When a continuation of black picture elements is present after the continuation of a regulated number or more of while picture elements, the boundary between the initial white picture element and black picture element is taken as one point on the edge. In a straight line calculating means, linear expression calculation and abnormal data removing processing are performed. The processing is repeated until conversion is attained.  Since the binarized level is regulated to determine the final approximate expression while judging the quality of the approximate expression calculated by the picture element recognized as the edge, the edge can be satisfactorily enciphered.

Title: Original size detecting unit of copying machine
Inventor: YUGAWA KOUJI
IPC: G03G15/00
Filed: 1979-08-01
Abstract: PURPOSE: To detect an original size accurately to prevent the erroneous operation for form selection, by not using a projector but using a coloring material to detect the original size by a color sensor.  
     CONSTITUTION: When platen cover 5 is opened, the external light incident to the part of color plate 3 or 3' which is not covered with original 2 is reflected as the color light of a specific wave length by reflection color plate 3 and is incident to color sensor 4 through transparent color plate 3'. Therefore, color sensor 4 corresponding to the part which is not covered with original 2 shows the output corresponding to the specific wave length, and other color sensors show a different output, so that this information can give size information of original 2. When platen cover 5 is closed, start switch 6 is operated, and selection and supply of a form based on information of color sensors 4 is performed by the selective supply circuit. Thus, the erroneous operation for form selection can be prevented.

Title: Fuel gauge for vehicle
Inventor: KAGARI KOUZOU
IPC: G01F23/24
Filed: 1986-04-25
Abstract: PURPOSE:To correctly display the consumption of fuel, by a method wherein the resistance value of a liquid level detector when a full tank sensor detects a full tank state is compared with a reference resistance value to correct the output signal of a display part and an indicator is moved to an E-side immediately after a liquid level is lowered. CONSTITUTION:When fuel is injected in a fuel tank 1 so as to reach a full tank state, the position of a float 7 and the resistance value of a liquid level detector 6 corresponding thereto also become irregular with the irregularity of a liquid level. Then, the resistance value of the detector 6 when a full tank sensor 13 detects a full tank state is compared with the reference resistance value corresponding to the F-position of the indicator of a display part 12 to correct the output signal to the display part 12 corresponding to the difference between both values and the signal corresponding to the reference resistance value is always outputted. The output signal based on the reference value of the detector 6 changes from the value corresponding to the reference resistance value position at the time of a full tank corresponding to the lowering in the liquid level and the float 7. Therefore, the indicator of the display part 12 always shows the F-position at the time of full tank injection and immediately moves to an E-side with the lowering in the liquid level.

Abstract: PURPOSE:To develop a difference of water pressure between the lower end section of a water pumping pipe and the hole section of a returning pipe to circulate naturally the water and also save power required for heating the water by keeping the inside and outside of a double walled pipe connected to a heat pump from contacting the atmosphere. CONSTITUTION:The end of a water pumping pipe 4 with double walls is placed in a underground water layer 9 in a deep stratum and a return water pipe 5 is welded to the water pumping pipe 4 and its end is sealed. Water storage pumped up by a water storage pump 6 positioned at an intermediate position of the water pumping pipe 4 goes into a heat pump 1, and the water heated there is sent to a group of heat pipes to a heat plate 3 and then returned again to the heat pump 1 to be circulated. The pumped water storage is returned to a stratum that has high permeability to water and is located near the ground surface. Because at this time the pumped water storage does not come in contact with the air, the water circulates without driving the water storage pump 6.

IPC: H01F19/00
Filed: 1989-04-18
Abstract: PURPOSE:To surely execute a multiple split winding operation without using a bobbin and to make a magnetic flux distribution of a leakage flux comparatively uniform by a method wherein a polygonal closed magnetic circuit magnetic core of at least a pentagon or more is used and this choke coil is constituted by splitting and concentrating windings on individual straight-line parts of a magnetic path. CONSTITUTION:Split windings 4 to 7 of a first coil 2 are wound on straight-line parts 12 to 15 of a magnetic path of an octagonal closed magnetic circuit magnetic core 1. Then, split windings 8 to 11 of a second coil 3 are wound on straight-line parts of a magnetic path of the same magnetic core 1. However, winding directions of the two coils 2, 3 are set in such a way that they offset a magnetic flux generated by a line current. Thereby, since a structure to reduce a distributed capacitance is formed, it is very effective for an attenuation amount in a high-frequency region against a common-mode noise even when an inductance identical to that of conventional constitutions is in addition, even when a bobbin is not used, a split winding operation can be executed surely when the required number of straight-line parts of the magnetic path are available.

Title: Support structure of in-tank type fuel pump

IPC: F02M37/10
Filed: 1993-03-31
Abstract: PURPOSE:To reduce ineffective fuel that cannot be utilized by installing a fuel pump detachably on a pump support member fixed to the bottom plate of a fuel tank. CONSTITUTION:A fuel pump 14 is installed directly to three columns 13 which are spot-welded on the upper surface of a sub-tank 12 welded to a lower tank 11b of a fuel tank 11. Therefore, the clearance between a filter 18 and a sub- tank 12 can be reduced. Also, because a fuel pump 14 is deformed similarly when the lower tank 11b and sub-tank 12 are deformed elastically by impact from the outside, the fuel pump 14 will return to the original position if the lower tank 11b, etc., returns back to the original position. Therefor, any problem will not occur. Also, even if the internal pressure of the tank varies according to a variation in fuel amount, and also the distance between the upper tank 11a of the fuel tank 11 and the lower tank 11b varies, a positional relation among the fuel tank 14, lower tank 11b, and sub-tank 12 does not vary, and the sucking capacity of the fuel pump 14 is kept unchanged.
