IPC: H04B1/7085
Filed: 1987-12-18
Abstract: PURPOSE:To improve the detection probability of a PN code by devising the device such that the phase of a reference carrier is arranged to the phase of a carrier of a reception signal. CONSTITUTION:The device is provided with a control voltage generator 23 generating a control voltage based on an output of a soft decision circuit 22 applying soft decision to an output of a sample and hold circuit S/H 3(21) sampling a level of a square device 2(13), a voltage controlled oscillator 24 controlling the oscillated frequency based on the control voltage, a comparator whose threshold level is lower than the comparator 15, a comparator 1(26) comparing the output of the square device 1(12) with the preset threshold level and an acquisition circuit outputting the output of the comparator 1(26) externally and an output terminal 27. Then a control signal is generated based on the output of the 2nd correlation device 11, the oscillated frequency of the reference carrier is controlled based on the control signal to compensate the phase difference between the reception signal and the reception carrier. Moreover, the output of the 1st correlation device 10 is used to apply the decision of the acquisition of the PN code. Thus, the acquisition probability of the PN code is improved.

Title: Preparation of preform for polarized wave-maintaning optical fiber
Inventor: KUROODO BUREMU
IPC: C03C13/04
Filed: 1989-12-08
Abstract: PURPOSE: To obtain a preform that can be drawn to a fiber allowing easy coupling without loss to a circular fiber, by arranging respectively two pieces of oblong elements of silica doped with boron oxide and titanium oxide on the outside face of a basic preform so as to constitute a cylindrical shape.  
     CONSTITUTION: The basic preform 1 of a monomode manufactured by, for example, an MCVD method is prepd. Similarly, a tube 5 consisting of a silica supporting tube 6 having the silica 7 doped with boron oxide and a tube 8 consisting of a silica supporting tube 9 having the silica 10 doped with titanium oxide are prepd. Next, the tubes 5, 8 are cut along the two planes intersecting with each other along the axial line by a diamond saw, to form the elements 15, 18. The two elements 15, 18 are arranged symmetrically opposite to the preform 1 around the orthogonal planes 20, 30 intersecting with each other along the axis thereof and are so compensated that the four elements constitute a cylindrical shape. For example, a silica tube 14 is therefore arranged around the assembly and is crushed by heating under a reduced pressure.

Title: Controller for vehicle driving output
Inventor: TERAKAWA TOMOMITSU
IPC: F02D29/02
Filed: 1993-12-20
Abstract: PURPOSE:To dispense with releasing and resuming shift-down operations in the traveling on upward and downward slopes to improve the durability of a transmission by releasing the shift-down operation on the flat path without releasing the same of the transmission in the travelling on the upward and downward slopes. CONSTITUTION:When a main switch 1 is closed and vehicle speed detected by a vehicle speed detecting means 7 is gradually more than desired vehicle speed so that vehicle speed deviation is decreased toward a negative predetermined value, a throttle value 9 is controlled and an ATM 18 is automatically shifted down when the vehicle speed deviation is below the predetermined negative value. Thus, the vehicle speed is once returned to the desired one. However, since the vehicle speed falls a bit below the desired one by acceleration, the opening of a throttle is opened and the shift-down condition is maintained until the travelling of the downward slope is completed. The opening of the throttle is enlarged on the flat path and the shift-down operation is released when the vehicle speed exceeds the sum one of the reference throttle opening and predetermined value.

Title: Communication channel management system in isdn private branch exchange
Inventor: KAWANO TAMAKI
IPC: H04Q3/58
Filed: 1993-12-21
Abstract: PURPOSE:To always secure a communication channel with respect to a dial/call reception request with high priority by grouping communication channels in combination with a DDI (direct dial-in) service. CONSTITUTION:A central processing unit receiving an outgoing call/an incoming call (S1) hunts an idle communication channel from among available communication channels in a DDI number zone terminal group to which a caller/called party number belongs (S3, routine Yes in S4A-S4D, S5) when the caller/called party number is in existence in a received message (routine Yes in the step S2). When all communication channels assigned to the DDI number zone are already busy (routine No in S4A-S4D), the received outgoing call/incoming call is rejected (S7) even when an idle communication channel is in existence in communication channels assigned to other DDI number zone. Furthermore, when no outgoing call/incoming call number is in existence in the received message (routine No in S2) or the outgoing call/incoming call number does not belong to any group (routine No in S3), the central processing unit regards the call to be equal to an outgoing call/an incoming call of a representative terminal equipment and implements the processing in the step S4A.

Title: Peak hold circuit
Inventor: MATSUMOTO TAKASHI
IPC: G01R19/04
Filed: 1992-12-01
Abstract: PURPOSE:To provide a peak hold circuit which can sustain the peak value of input signal as an output signal with high accuracy. CONSTITUTION:An analog input signal Vin is fed to one input terminal of a comparator 2 which delivers an output signal to a state decision circuit 6. The state decision circuit 6 delivers an output signal, which goes H level when an output signal from the comparator 2 is sustained at H level for a predetermined time or more, to a counter circuit 3 where the number of pulses of the output signal is counted. An output signal from the counter circuit 3 is fed to a D/A converter 4 where the number of pulse is converted into an analog voltage. The D/A converter 4 produces an analog output voltage in the form of an output signal VH which is fed back to the other input terminal of the comparator 2.

Title: Settling of pipeline
Inventor: KOTSUKI ZENJI
IPC: G01M99/00
Filed: 1987-12-18
Abstract: PURPOSE:To bring about settling displacement of pipes by simplified equipments by a method in which a pipe set in the bottom of an excavated trench is buried in a soluble solid, a frozen settled layer is formed through a freezing liquid, and a heat source is supplied through pipe set in the layer to thaw the ice. CONSTITUTION:A pipe 2 is set in the bottom of an excavated trench 1 with a pipeline 5 and buried in soluble solids to a given level in order to form a settled layer 3, where the layer 3 is watered and at the same time frozen through a refrigerant. The pipeline 5 in the upper part of the layer 3 is finished and the the soil to the ground is compacted. The frozen water of the layer 3 is thawed by supply or circulation of heat source into the pipe 2 in the layer 3, and the solids forming the layer 3 are dissolved by the thawed liquid so that the upper pipeline 5 of the layer 3 and the deposit soil are settled down by a degradation phenomenon similar to the ground subsidence. Experimental measurement on displacement of the pipeline by the ground subsidence can thus be eliminated, and the operation is economically performed without specific technique.
