Title: Steel mesh-reinforced synthetic resin plate for detection of underground electric circuit
Inventor: YOTSUGI MASAZO
IPC: E02B9/06
Filed: 1987-04-16
Abstract: PURPOSE:To eliminate positional deviation due to variation of an automobile or the like running on a road surface while preventing breakage otherwise caused by hitting with the tip of an excavating machine, by burying a wire netting reinforcement into a synthetic resin plate in such a manner that the surface of either vertical or horizontal steel wires thereof are exposed. CONSTITUTION:A synthetic resin plate 4 is buried into a path with the side of a wire netting 1 upward. The wire netting is so arranged that either vertical iron wires 2 or horizontal steel wires 3 are exposed to the surface of the resin plate 1. With such an arrangement, a radio wave emitted from a transmitter of a detector hits the wire netting of the resin plate 1 and flows therethrough to be trapped with a ground receiver, which enables the detection of the layout position of the resin plate 1. An electric circuit pipe is right below the resin plate 1 and allows the detection of the layout position of the electric circuit pipe. Then, excavation is performed with a screw type excavator at the location detected, and when the tip thereof hits the resin plate 1, the downward travelling thereof is blocked with the steel mesh on the surface thereof to spot the position of the resin plate exactly. In addition, the resin plate 1 is so hard and weights so much that it will not move under ground even subjected to vibration caused by an automobile or the like running on a road surface.

Filed: 1987-04-20
Abstract: PURPOSE:To extend discharging time of the try cell in the caption under a heavy load by charging black mixture for cell whose ratio by weight of acetylene black to manganese dioxide is specified and adjusted to 6/94 in a can of zinc. CONSTITUTION:Black mix for cell whose ratio by weight of acetylene black whose quantity of absorbing hydrochloric acid prescribed in JIS K-1469 is more than 20ml/5g and manganese dioxide is adjusted in the range of 12/88-6/94 is charged in a can of zinc. A dry cell with excellent heavy load discharging characteristic can not be obtained under the condition that the quantity of absorbing hydrochloric acid of acetylene black is less than 20ml/5g, because the quantity of electrolyte held in it is lessened. Under the condition that the ratio by weight of acetylene black to manganese dioxide is less than 12/88, excellent heavy load discharging characteristic is achieved but long time discharging can not be carried out, and in case of exceeding 6/94, charging quantity of manganese dioxide becomes large but its utilization factor goes down and also the quantity of electrolyte held in it is lessened. Accordingly, a manganese dioxide try call with more than 50% of utilization factor and excellent heavy load discharging characteristic cen be obtained.

Title: Method for measuring occluded amount of hydrogen
Inventor: TAKEGAWA YOSHINOBU
IPC: G01N33/20
Filed: 1989-04-15
Abstract: PURPOSE:To make it possible to measure the amount of occluded hydrogen by measuring the amount of deuterium which is discharged from a metal material in a highly vacuum state. CONSTITUTION:A metal material 2 which occludes hydrogen is used as a cathode. A platinum plate 5 is used as an anode. The metal material 2 and the platinum plate 5 are immersed in electrolyte 1. When electrolysis is performed with a DC, hydrogen ions in the electrolyte 1 become hydrogen at the generating period, and the hydrogen is occluded into the material 2. At this time, when heavy water is added into the electrolyte 1, deuterium ions are generated from the cathode, and the deuterium is occluded into the material 2. The material 2 is set in a vacuum chamber 8 which is connected to a mass spectrometer 3 and a vacuum pump 7. The inside of the chamber 8 is made to be a high vacuum state with the pump 7, and the material 2 is heated with a heater 9 at the same time. Therefore, the deuterium is discharged from the material 2, and the discharged amount is measured with the spectrometer 3.

Title: Electroslag welding method of vane wheel
Inventor: KAMEI HIROMASA
IPC: B23K25/00
Filed: 1978-08-08
Abstract: PURPOSE:To enable welding of high efficiency to be performed irrespective of plate thicknesses by providing a groove of the size permitting the formation of at least a minimum of molten slag amount required in the face plate at the time of welding moving vanes and the face plate of the vane-wheel. CONSTITUTION:The molten slag 12 amount is expressed by the product of its height h and the thickness t and spacing w of the works 11. At excessively small h and w, there are troubles such as failure in melting of a wire 6 and difficulty in transfer of heat to groove faces. In this way, the required amount of molten slag is determined by conditions such as t and w. Next, the face plate 1' is made thick in plate thickness T2 for the prevention of its information. A water cooling pipe pad 4 is formed to the shape which is rounded to R at the neck of the moving vane 2. A groove 21 is worked in the face plate 1' and its width W is made preferably smaller than the shape R as it expands by the effect of heat but if this is infeasible on account of the slag amount, it may be covered by the shape of the pad. The depth P of the groove is desirably equal approximately to the width W because the molten slag heat distributes with the consumable electrode 5 and welding wire 6 as a center, but selecting the same at the required amount of the molten slag suffices.

Title: Cylinder head for diesel engine
Inventor: AOKI SHIGEO
IPC: F02M35/10
Filed: 1980-07-14
Abstract: PURPOSE: To increase the combustion efficiency of a diesel engine, by forming two intake passages for a single intake-valve port, and imparting swirl to the intake air introduced into a combustion chamber.  
     CONSTITUTION: Two intake passages 19, 20 extended from both sides of a cylinder head 11 are directed reversely to each other on the opposite sides of a central valve guide portion 16 for an intake-valve port 12, and guide walls 21, 22 are formed on the outer surface of the valve guide portion for leading the intake passages 19, 20 in the manner that they get under the other respectively and thereby imparting swirl to the intake air drawn from these two intake passages in the same direction around the guide portion. With such an arrangement, it is enabled to prevent collision or interference between intake airs introduced from the two intake passages to the valve port 12 and to turn the intake airs smoothly around the valve guide portion 16 and a valve rod 14. Since a strong swirl is thus produced in the combustion chamber, the combustion efficiency of the engine can be raised.

IPC: G06F13/36
Filed: 1985-05-07
Abstract: PURPOSE:To shorten the data transfer time required for memory read/write by controlling bus acquisition control, address transmission, and address discrimination in parallel. CONSTITUTION:Since a bus acquisition permitting signal AVCPU of a processor 10 is always effective, address transmission to an address/data bus 15 and bus precedence control of a bus arbitrating circuit 12 are performed in parallel. If an address bus 17 is used by another I/O device or the like, the output address of the processor 10 is held in an address holding circuit 21 until the use of the bus 17 is terminated. Since the address outputted from the processor 10 is discriminated by an address discriminating circuit 22 in the side of the processor 10, discrimination can be controlled in advance and a memory 14 is operated by a memory operation request signal RAMST immediately when the bus is acquired. Thus, bus request, address transmission, and address discrimination are operated in parallel with respect to time.
