Title: Method for forming conduit run inner pipe
Inventor: SAKURAGI HIROYUKI
IPC: F16L1/00
Filed: 1993-06-07
Abstract: PURPOSE:To keep a hard thermoplastic resin pipe flat even when it is heated and insert the pipe easily into a conduit run by folding the pipe into flatness, blocking both ends of the pipe airtightly, bending the pipe to make the cross section almost a V or U shape, inserting the pipe into the conduit run, and expanding the pipe by applying hot pressurized fluid to the pipe. CONSTITUTION:A synthetic resin pipe 1, which is preferably made of rigid high density polyethylene or linear low density polyethylene, is folded into flatness, wound on a reel, and blocked by filler airtightly. The pipe 1 is passed trough a heater, softened by hot air supplied from a hot air supply pipe 6, pressed on its middle part by a rotary roller 7 to be bent with the cross section made almost a V or U shape, and inserted into the conduit run 2. The resin pipe 1 the end of which is connected with a draw wire 8 previously inserted into the conduit run 2 is drawn by the wire 8 to be inserted into the conduit run 2. The end of the pipe 1 is cut, and the pipe is expanded by applying pressurized steam to make it cylindrical so that the pipe runs along the inside of the conduit run 2.

Abstract: PURPOSE: To effectively utilize the existing supply facility to the maximum extent by operating a flow-out equipment at less than the maximum flow rate, operating a flow rate equipment at above the maximum flow rate, and stopping the operation until the supply facility reaches a predetermined capacity. CONSTITUTION: A central control device 44 sets respective upper limits of flow rates of lavatory S and/or waterworks supply pipe communicating with a group under management, operates an electromagnetic valve for which operation demand is given selectively, and prevents the operation from occuring even in a urination device U, a feces device T or a washstand S which are flow-out equipment properly if an emergency case occurs. Furthermore, even if sufficient supply of water is obtained, programming to delay the operation for a fixed and selected period of time is done for a water supply facility, and an upper limit of flow rate allowed for individual water supply pipes is adjusted to ensure the maximum use of drinking water supply. Consequently, it is possible to expand a specific water supply facility even if a water supply main pipe has no capacity for supplying all water.

Title: Production of substrate for tft array
Inventor: TAKANABE SHOICHI
IPC: C23C16/42
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent a metal film from being broken at an SiN stepped part by depositing SiN film at a specified deposition rate by plasma CVD. SOLUTION: The graph shows the relationship between the deposition rate of SiN film composing an interlayer insulation film and the amount of undercut of SiN film when a contact hole is made in the SiN film on an ITO film composing a pixel electrode. The amount of undercut of SiN film has a minimum value. Consequently, when it is set at about 20 nm or less, for example, the deposition rate of SiN film must be set in the range of 10-50 nm/min. According to the method, the amount of undercut of SiN film on the ITO film can be controlled in etching in TFT array process by regulating the deposition rate of SiN film, as an insulation film, on the pixel electrode or an interconnection composed of ITO film.

Abstract: PURPOSE:To newly input a character by erasing all characters that are displayed on a character-string input area, in case a correction key is depressed in a state that a cursor is positioned in the head of the character-string input area. CONSTITUTION:In case it is decided that a correction key 2D is depressed, by key scanning, a host computer 13 decides whether a cursor is positioned in the head of a character-string input area displayed on a CRT screen or not, and erases all the characters of the character-string input area, in case when it is decided that the cursor is in its position. On the other hand, in case it is decided that the cursor is not positioned in the head of the character-string input area, a character before the cursor is erased. Also, in case a back-space key 2E of a keyboard 2 is depressed, the character before the cursor is erased, and in case a forward key 2F is depressed, a character on the cursor is erased. In such a way, the character-string input operation can be executed easily, and a memory editing time of a text, etc. can be shortened.

Title: Antenna system
Inventor: CHIBA ISAMU
IPC: H01Q3/38
Filed: 1986-07-14
Abstract: PURPOSE:To shorten the time needed for calculation of the phase setting value by limiting the number of element antennas applying the nonlinear optimization method. CONSTITUTION:The radio waves received by element antennas Ea1-EaN undergo the phase shifts through phase shifters Ps1-PsN and synthesized by a synthesizer 1. These synthesized radio waves are transmitted to a receiver 2. Each phase shifter is set by a phase shifter controller 3 based on the calculation of a control processor 4. A phase shifter selecting circuit 6 sets the sensitivity at zero in the undesired wave arriving direction instructed by an angle instructing circuit 5 and at the same time compares a phase component PAi having a complex exciting amplitude that turns a main beam to the desired direction with the phase setting value POi which turns merely the main beam to the desired direction. Then the circuit 6 selects only the phase shifters having the difference ¦PAi-POi¦ is larger than half the minimum cut angle alphaB of the phase, shifter. The processor 4 applies the nonlinear optimization method to the selected phase shifter only. Thus it is possible to form the main beam and the zero-point sensitivity in each desired direction in a short time.
