Title: High-frequency amplifier
Inventor: SAITO MASAO
IPC: H03G1/00
Filed: 1988-02-22
Abstract: PURPOSE:To prevent the leakage of a high frequency by providing a shatter to open/close a waveguide opening to an output waveguide, and blocking the shatter and terminating the high frequency when a connecting waveguide is not connected. CONSTITUTION:An output waveguide 3 is provided to rock a shatter 6, capable of blocking a waveguide opening at a fulcrum 6a. When a waveguide 4 is not connected, since a pin 8 is evacuated from an operating part 6b, the shatter 6 blocks the waveguide opening.

Title: Call setting system for node and network
Inventor: MORI ATSUKO
IPC: H04Q3/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce a cumulative delay time for each repeating node and to enable an immediate connection service by setting a previously secured path (PVC) between outgoing and incoming nodes on an exchange network before the start of a call setting service and directly setting a call from the outgoing node to the incoming node without performing repeating processing at the repeating node concerning call setting accepted at the outgoing node. SOLUTION: A PVP 27 is previously set between an outgoing node 20 and an incoming node 40 through a repeating node 30. The outgoing node 20 receives a call setting request from a call originating user 10 to a call terminating user 50 through an SVC call origination accepting means 21 and selects any PVP usable for a routing managing means 26 and a routing managing table 25 through an SVC relay connecting means 22 and the call originating user 10 and the call terminating user 50 are turned into communication state through an SVC relay connecting means 42 and an SVC call incoming control means 49 at the incoming node 40. Thus, the repeating processing at the repeating node 30 can be eliminated and the time for processing at the repeating node 30 can be shortened.

Title: Communication equipment of spread spectrum system and synchronism acquiring method
Inventor: NARUSE MASAO
IPC: H04B1/707
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To quickly attain the synchronism acquisition of a spreading code even in the case of that a non-negligible frequency error exists in the spreading code of a transmitting side and a receiving side. SOLUTION: At the receiving side, the detecting operation of an optimum phase Pmax in which a correlation value becomes maximum is executed in a prescribed phase range while sliding the phase of the spreading code (PN code) by every definite amount at a bit period. Narrowed phase ranges with the width of ΔL are set before and behind Pmax, and after shifting the phase of the PN code to its beginning point at high speed, next sliding search is executed, and the similar search is repeated until ΔL becomes below a threshold. At the point of time when ΔL becomes below the threshold, the synchronism acquisition is completed.  The shifting direction of the optimum phase is stored beforehand during a search process, and in the case of 'out of synchronism', a system is returned again to a synchronized state by shifting the PN code of the receiving side to the prescribed direction by one-chip portion. Since the oscillator with comparatively low precision is applied to the receiving side, a portable terminal is made inexpensive.

Abstract: PURPOSE:To secure a constant flow regulating valve in an inexpensive structure by installing a lift-type flow regulating valve being throttled along a flow direction in an inlet passage formed by a partition part, and a lift-type slide valve being closed against the flow direction in an outlet passage, respectively. CONSTITUTION:When a lift-type flow regulating valve 5 is in a state of being fully opened, a stream flows into those of inlet bore part passage (a)   inlet passage (b)  flow regulating opening part (c) intermediate passage part (d)   slide valve opening part (e)   outlet passage (f)   outlet bore part passage (g) in order as keeping the specified maximum flow rate. In this state, force in a direction of opening the opening part (e) of an equalizing spring 9 is being balanced with a pressure differential between an intermediate passage (d) working on each pressure receiving surface in front and in the rear of an end member 7h and a bladder chamber (h), namely, the inlet passage (b). Next, in order to do flow regulation, when a valve regulating knob 4 is turned and controlled and the opening part (c) is being throttled by the valve 5, passage resistance increases, therefore pressure in the passage (d) at the downstream side goes down and thereby balance by the spring 9 is upset, and simultaneously the opening part (e) of a slide valve 7 comes to such a regulating passage as far as a degree commensurate to the flowing state.

Title: Construction method for basement
Inventor: KUROYANAGI NOBUYUKI
IPC: E02D29/00
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To secure constant reaction force even in the soft ground by injecting an improving agent in the ground to form a soil improvement body, and supporting the reaction force on the soil improvement body to press a side wall panel of a basement into the ground. SOLUTION: In drilling the ground using an auger, while an improving agent like a cement milk is injected, it is stirred and mixed with excavated sediment to be cured and hardened, thereby forming a column-like soil improvement body 2. Four side wall panels 4 constituting a basement are installed in designated positions, and held on a rectangular box constituting the basement by a temporary support jig. Secondly, by propulsion force of a jack device 12 where reaction force is supported by a connector 11, the upper edge of a side wall panel 4 positioned between a pair of soil improvement bodies 2 is pressed, and the side wall panel 4 is synchronously kept in the vertical state, and also pressed in the ground by pressurizing force of the jack device 12, thereby excavating soil in the side wall panel 4 to form a basement space.  Thus, a comparatively simple construction method can be uniformly adopted regardless of the ground state so as to lessen the burying position correction work for the side wall panels.

Filed: 1993-03-01
Abstract: PURPOSE:To make it possible to use a casing pipe, which is light weight and low cost, and which is easy to join and disassemble and hence improve excavation speed in terms of a construction method which reinforces the inner peripheral surface of a excavation hole formed with an excavation tool with a casing pipe. CONSTITUTION:A casing tool 20 is inserted into a casting pipe 21 whose is similar to the casing tool.
