Title: Trench timbering, and bag body for timbering
Inventor: YANAGIMOTO HAYAO
IPC: E02D17/08
Filed: 1995-03-22
Abstract: PURPOSE: To execute installation and removal of timbering efficiently without requring much labor and a large-scaled machinery equipment and without producing much noise and vibration by a method wherein a bag body is put in an excavated trench and the laterals of the bag body are pressed against the trench with the pressure of a fluid injected into the bag body kept at the middle between the active earth pressure and the passive earth pressure of the trench wall. CONSTITUTION: After a bag body 4, being in the contracted state, is lifted down into an excavated trench 1 and settled at the bottom 3 of the excavated trench 1, a fluid such as compressed air is injected into the bag body 4 with a fluid supply apparatus 9 provided at the outside of the excavated trench 1. On injecting the fluid, the pressure P of the fluid is kept at the middle of the active earth pressure and the passive earth pressure of the trench walls 2, and the laterals of the bag body 4 are pressed against the trench walls 5. The bag body 4, being inflated and settled in the excavated trench 1, functions as a retaining wall body and a trench timbering so long as the pressure P of the fluid is kept at a specified level, and laying of underground equipment in areas adjoining the part where the bag body 4 is installed can be executed safely.  The bag body 4 can be contracted with the fluid discharged, and lifted up for removal.

Title: Method of bonding glass part
Inventor: NAGANO TOSHIKI
IPC: C09J5/00
Filed: 1989-04-11
Abstract: PURPOSE:To bond a glass part to a holding frame without squeeze-out of an adhesive into the opening of the holding frame by applying a rapidly curing first adhesive to form a barrier on the side where the squeeze-out of an adhesive should be prevented, applying a second adhesive to a thin coat on the side where the adhesive may be squeezed out, attaching a glass part to a holding frame, and pressing it. CONSTITUTION:A rapidly curing first adhesive 14 is applied to the peripheral edge 13a of the central opening 13 of a holding frame 12 to form a thick coat so as to be protuberant and it is cured so that an adhesive is prevented from being squeezed out. A second adhesive 15 is applied near the peripheral edge 112a of the central recess 12a of the holding frame 12, which is on the side where the adhesive on the adherend 12b may be squeezed out, in such a manner that it is not overlaid on the first adhesive 14 and it forms a coat thinner than the first adhesive 14. When a glass part 11 is joined to the recess 12a of the holding frame 12 and pressed, the first adhesive 14 is deformed to produce a barrier, thus preventing the squeeze-out of the second adhesive 15 due to flowing by pressing. Thereafter the first adhesive 14 and the second adhesive 15 are combined to form an adhesive layer 14a, which is cured to complete the bonding between the glass part 11 and the holding frame 12.

Title: Method of connection between cells for lead storage battery
Inventor: KAMIMURA SUMIO
IPC: H01M50/529
Filed: 1983-05-20
Abstract: PURPOSE:To keep off the occurrence of an internal short circuit in a lead storage bettery as well as to prevent its self-discharge characteristic from deterioration, besides shortening the service life, by eliminating a hermetical failure in a connecting part between each of cells. CONSTITUTION:A thick part 6 is installed in a connecting part between each of cells at the upper part of a battery jar's partition wall 4, while jogs 7 are installed in advance in a surface opposed to the thick part 6 of each of joint parts 3 and 3' rising from straps 2 and 2'. Having heated the thick part 6 with a hot jet or the like in advance, these joint parts 3 and 3' are pressed by a press or the like under pressure so as to cause these jogs 7 to be bitten into the thick part 6, and under this condition, these joint parts 3 and 3' themselves of each cell adjacent to the joint part are welded together at the upper part. Next, the vicinity of these joint parts are covered with antioxidation synthetic resin 5. With this constitution, a channel path along these joint parts 3 and 3' between adjoining cells becomes longer, while a positional slip in these joint parts 3 and 3' is in no case produced and, what is more, the antioxidation synthetic resin 5 goes around into clearance between these joint parts 3 and 3' at the lower part of the thick part 6 and the partition wall 4 whereby watertightness is secured and a liquid short comes to nil.

Title: Manufacture of field effect transistor
IPC: H01L29/812
Filed: 1992-03-14
Abstract: PURPOSE:To provide a method for manufacturing a field effect transistor which realizes a field effect transistor having high performance in high yield by burying ohmic electrodes and reducing a parasitic resistance between the ohmic electrodes in the transistor having an undoped GaAs layer on a substrate. CONSTITUTION:A low concentration GaAs layer (second undoped GaAs layer 5) on a surface is selectively etched by reactive ion etching, and an ohmic electrode 11 is formed on a high concentration N-type GaAs layer 3. Thus, a contact resistance of the electrode 11 with the layer 3 is reduced, and further since a part between the electrodes 11 is completely covered with the layer 5, a surface depleted layer is suppressed, a sheet resistance is also decreased, and an irregularity in a threshold value voltage due to a variation in a thickness of a channel film directly under a control electrode is suppressed, and hence a field effect transistor having high uniformity and high performance can be realized.

IPC: C04B20/06
Filed: 1995-03-23
Abstract: PURPOSE: To decrease the variations in sp. gr. and strength by pelletizing fly ashes from which unburned carbon materials are burned away and calcining these fly ashes in a prescribed temp. range in an atmosphere of a specific oxygen concn., thereby producing artificial aggregate suppressed in foaming. CONSTITUTION: The fly ashes from which the unburned carbon materials are removed by heating for about 2 to 5 hours at about 600 to 800 deg.C are used as raw materials. Pelletizing materials selected from clays of bentonite, kaolinite, etc., and compactness accelerators selected from CaCO3 , Ca(OH)2 , etc., are added and mixed at a ratio of <=40 pts.wt. in total with 100 pts.wt. fly ashes and the mixture is dried after humidifying and pelletizing, by which pellets of a grain size of about 10 to 15mm are produced. These pellets are inserted into a furnace of an atmosphere adjusted to an oxygen concn. of <=5vol.% as a gaseous mixture composed of nitrogen or Ar and oxygen and are calcined by suppressing foaming at 1300 to 1450 deg.C, more preferably about 1325 to 1425 deg.C, by which the dense artificial aggregate having a large sp. gr. is obtd.

Title: Ink jet head
Inventor: KOMAI HIROMICHI
IPC: B41J2/02
Filed: 1985-04-26
Abstract: PURPOSE:To realize the removal of bubbles without requiring a specific pump or the like, by lessening the volume in a liquid chamber when ink starts to be sprayed. CONSTITUTION:When spraying is stopped, the passage between 1 and 3 of three-way valve 22 is closed, the passage of 1 and 2 being closed under a state where a valve 23 is closed and almost at the same time, the passages between 1 and 3 and between 2 and 3 of three-way valve 22 are open. Then, the inside of the second liquid chamber 15 becomes to be pressurized, the pressure in the first liquid chamber 14 being opened to the atmospheric pressure in a moment and ink stops to be sprayed. A vibration generation member 11 and elastic membranes 12, 13 are displaced to the first liquid chamber side by the pressure difference between the first and the second liquid chambers and the volume in the first liquid chamber 14 is lessened. When spraying is started, by leaving the passage between 1 and 2 of valve 22 open and the passage between 1 and 3 closed as they are and by making the passage between 1 and 3 of valve 21 open and the passage between 1 and 3 closed, the ink from the ink supply system is recovered to the ink supply system via the inside of the liquid chamber 14 and the valve 22. Because the volume in the first liquid chamber 14 is small, the bubbles in the liquid chamber can be easily removed. Then, by making the passage between 1 and 3 of valve 22 open and the passage between 1 and 2 closed, the first liquid chamber 14 is, in a moment, pressurized by the pressure in the second liquid chamber 15 and the pressure from the ink supply system and spraying can be started without any leak of ink from the nozzle.
