Title: Pipe joint structure
Inventor: HASHIMOTO TAKAO
IPC: F16L21/04
Filed: 1993-01-28
Abstract: PURPOSE:To prevent coming-out of packing under both internal and external pressure by making up a packing with its heel and valve portions and holding the heel portion between the packing contact of a press ring member and the rear end face of a large-diameter pipe. CONSTITUTION:A bolt insertion hole 19 in a press ring 5 and a bolt insertion hole 9 in a flange 6 are brought together in phase, so that the press ring is attached to the end portion of a sleeve 7. The stepped portion at front of a packing 3 makes slight contact with the end portion 7c of the sleeve 7. In this state, a nut 4b of a tightening means 4 is tightened in rotation, so that the press ring 5 advances toward the sleeve 7 in large tightening force. The heel portion 12 of the packing 3 is thus strongly held between the packing holding face 20 of the press ring 5 and the sleeve 7. Then, an insertion pipe 2 is inserted into the sleeve through the packing 3. In this case, the packing 3 does not come out because the heel portion 12 of the packing 3 is firmly held with the press ring 5.

Filed: 1993-02-23
Abstract: PURPOSE:To reduce power consumption by providing a memory cell, a sense amplifier and an input/output circuit and performing a reading operation only when the potentials of a first bit line and a second bit line are made equal. CONSTITUTION:On a reading operation, at the time t1 a first control line 6 becomes L, a Pch transistor 2 is turned on, the potentials of bit lines 9 and 10 are made equal. At next time t2 the line 6 becomes H, the transistor 2 is turned off, and the potentials of the lines 9 and 10 do not change. At a next time t3, a word line 7 becomes H, the potentials of the lines 9 and 10 are changed by the data of a memory cell 3 and a potential difference is generated. At a next time t4, a control line 8 becomes H, a sense amplifier 4 is made operable and amplifies the potential difference of the lines 9 and 10. As a result, the data of the lines 9 and 10 become a power supply potential or a ground potential, the line 10 is connected to an output 11 of an input output circuit 13 and the data are outputted to an external. Thus, a reading is performed without precharging the lines 9 and 10 and by making the potentials equal. Therefore, power consumption is reduced.

Title: Recording medium material container
Inventor: MAEHARA YASUNORI
IPC: B65H1/26
Filed: 1985-02-20
Abstract: PURPOSE:To prevent a radiation recording medium from being damaged due to contacting caused by an allowance in size and also prevent it from falling down by arranging a recording medium holding means which is made of formed plastics provided with fasteners in a form of a face, on a part of the inner surface of the body of a container. CONSTITUTION:In order to allow an IP 26 to be put into the body 21 of a container, recording medium holding means 25 are arranged in the container. Both the tip end 26a which is firstly put in, and the tip end 26b of the other side which is secondly put in, are gradually pushed down under pressing the recording medium holding means 25 with pressure. Here, the recording medium holding means is composed of a soft member 25a and a hard member 25b provided with fasteners, accordingly, this enables the IP 26 which is contained in the body of the container, to be firmly held by the holding means. Therefore, the holding means can take the allowance of plus or minus 1mm of the IP 26 easily. This prevents the IP from being damaged by the relative contacting between IP 26 themselves preventing the IP 26 from falling down accompanied with the rising up or falling down of a bunk.

Title: Semiconductor device and production of the same
Inventor: UCHIYAMA YORIHIRO
IPC: H01L21/3205
Filed: 1979-03-20
Abstract: PURPOSE:To obtain a multi-layered wiring structure with a desired taper by preparing a wiring structure consisting of a lower layer of pure aluminum and an upper layer of Cu-added aluminum,  and subjecting the wiring structure to chemical etching. CONSTITUTION:A pure-aluminum layer 12 is formed by sputtering on a PSG film 11 formed on a Si substrate 10. An aluminum layer 13 containing approximately 4 wt.% of Cu is formed in the  same manner on the layer 12. A resist mask 14 is formed on the layer 13, and the aluminum is  etched with a mixture of sulfuric acid, acetic acid and nitric acid. As a result, the layer 13 is  etched early so that the aluminum layers are changed into a trapezoidal form having an angle theta  of 60-70 deg.. In the resulting wiring structure having such an angle as mentioned above, breaking  of wire never occurs. When an etching solution consisting of the above-mentioned mixture and water, in which the composition ratio of sulfuric acid, acetic acid, nitric acid and water is  16:1:1:2, is used, a wiring structure having a smooth and ideally curved bottom surface can be  obtained. According to this method, aluminum wiring with a desired taper can be obtained by simple etching, and this method can be advantageously used to form a multi-layer wiring structure. Moreover, this wiring structure has a high electromigration resistance, and permits maintaining a high current density.

IPC: B64C31/036
Filed: 1988-02-16
Abstract: PURPOSE:To make safe flight possible by providing a flexible wing forming a wing shape by filling gas within a wing. CONSTITUTION:A glider 1 is composed of a flexible wing 2, the harness 3 retaining the body of a pilot 6, and a rope 4 connecting the wing 2 and the harness 3. The wing 2 is formed with plural sub-wings having high gastightness, and a gas injection port 5 is attached to the part of the wing. A valve 7 is attached to the port 5, and the air supply/discharge to the wing is conducted by the opening/closing of the valve 7. At first, a wing shape is formed with a gas lighter than air such as, e.g., hydrogen and helium etc., injected from the port 5. Then the harness 3 is attached to the body of a pilot 6. A safe take-off can be made since the wing is already floating in the air in this condition. And safeness is high since the gas in the whole wing is not released even if its part is damaged since the wing is composed of plural gastight chambers.

Filed: 1978-03-24
Abstract: PURPOSE: To achieve the simplification and cost reduction of a character printer by recording character patterns on holograms of minute areas by the use of the features of holography techniques and exposing the reproduced images from the holograms directly to a photosensitive material.  
     CONSTITUTION: The use of holography techniques enables information to be recorded at high density and the application of this feature to recording of character patterns enables a large volume of character patterns to be recorded in a relatively small area. A character plate 8 having been recorded with a large volume of character patterns in small areas in this way is rotated in the forward and backward direction by character access signals and is so controlled that the holograms 9 having been recorded with desired characters come to the radiation position of a fixed reproducing beam 12. The position detection of a driving system 11 is accomplished by detection of the address marks 10 provided to the character plate 8 in opposition to the holograms 9 or by a rotary encoder or the like.
