Title: Mobile communication system having hierarchical structure
Inventor: AKIYAMA AKIFUMI
IPC: H04B7/26
Filed: 1989-08-14
Abstract: PURPOSE:To realize an economical system by constituting the service area with a small radio zone, a medium radio zone including small radio zones and a large radio zone including medium radio zones in a hierarchical way and deciding the location registration method among them and the call method based thereon. CONSTITUTION:The service area is constituted in a hierarchical way such as small radio zones, medium radio zones including the small radio zones and large radio zones including the medium radio zones. The position of a mobile terminal equipment is registered in a small zone area when it stays in the small radio zone and registered in a medium zone when the terminal equipment reaches the medium zone area at the outside of the small radio zone. However, no position registration is implemented even when the terminal equipment reaches a large radio zone at the outside of the medium zone area. An exchange station calls the zone in which the position of the terminal equipment is registered at the arrival of a call. If no reply comes from a small and a medium zone, a large zone is called to inform the arrival of the call to the mobile terminal equipment and the exchange station requests the mobile terminal equipment to move the medium or small zone area for its access. Then the user moves to the small zone or the medium zone and accesses the control station from the mobile terminal equipment.

Title: Continuous heating furnace in hot rolling line
Inventor: USHIJIMA SHIGEMI
IPC: C21D1/00
Filed: 1985-09-19
Abstract: PURPOSE:To reduce the idle time of a titled furnace and to save the energy consumption in rolling, by dividing the moving hearth of the furnace into three parts to make each part drivable by each driving device, and discharging and continuously charging a stock to be rolled at the same time by the chageover of a driving mechanism. CONSTITUTION:When a cast stock to be rolled, a bloom, is continuously charged into a heating furnace T at a prescribed charging speed, respective beams B1-B3 are interlocked by connecting mechanisms 31, 32 and are driven synchronously. The stock is heated by a burner and conveyed to the discharging end. When all the stocks are charged into the furnace T and the most preceding stock arrives at the discharging position, the beam B1 is separated from the beam B2 by a control circuit through the mechanism 31, and the beams B2, B3 are interlocked through the mechanism 32 to perform idling by the actuation of an eccentric ring 1. A group of rolling stocks are discharged after a prescribed time, by synchronously driving the beams B2, B3. When the new manufactured blooms are charged onto the beam B1, and the stocks on the beam B2 are transferred onto the beam B3; the beams B1 and B2 are interlocked by the mechanism 31 to convey the stocks, and the separated beam B3 continues to discharge the stocks.

Title: Ground evaluation test method for directivity controller for satellite antenna
Inventor: SEKINE KOJI
IPC: G01S3/42
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To conduct a test without providing effect onto a closed loop of a control test system by tracking a reference beacon being a directive object simultaneously while simulating an external disturbance on an orbit. SOLUTION: A reference beacon 1a emitted from a target 1 is reflected in an antenna 3 and given to an RF sensor 6 via a sub reflecting mirror 5 driven by an antenna drive mechanism APM 4. A null angle error of the target beacon received by a tracking receiver TRKRX 7 is given to a control circuit APE 8, which drives the APM 4 to cancel the error by means of a control algorithm in the APE 8. In this case, an external disturbance from an antenna pointing system APS test bench 9 is applied from the TRKRX 7 to the system of the APE 8. Then a directivity fluctuation in an RF is generated by a posture fluctuation of a satellite main body on which the antenna is mounted and the antenna directivity control system tracks the motion.

Abstract: PURPOSE:To partially oxidate toluene and to obtain benzaldehyde in a good yield by making toluene and an oxidizer react in an anode, making the hydrogen ions generated in the anode react with oxygen in a cathode to make into water, and repeating the opening and the closing of the circuit. CONSTITUTION:The reaction in an anode and a cathode when steam is used as the oxidizer can be shown in the following formulas. Anode: C6H5-CH3+ H2O C6H5-CHO+4H<-> (1), C6H5-CH3+2H2O C6H5-COOH+6H<+>+6e<-> (2), C6H5- CH3+7H2O 7CO2+36H<+>+36e<-> (3), and cathode: 1/2O2+2H<+>+2e<-> H2O (4). When a reaction gas is lead in a reaction device, a small amount of oxidation product is produced even in the condition to open the circuit immediately after the leading in, but it is disappeared soon. And the circuit of the fuel cell is repeated to open and close alternatively in order to increase the production amount of benzaldehyde. By repeating the opening and the closing of the circuit alternatively, a much larger amount of benzaldehyde can be obtained compared with the case of the circuit being closed.

Abstract: PURPOSE:To enable non-contact and exact detection of the temp. fluctuation in optical filters as light information by forming the two optical filters on the same substrate by using two kinds of materials having the different temp. coeffts. of refractive index. CONSTITUTION:The optical filters F1, F2 are formed by using the ring interferometers of the same shape and waveguides 5, 8, 9 (or 6, 10) are formed by using InP (or GaAs), on the substrate 7. A directional coupler 1 couples input light Pi to the filters F1, F2 and a coupler 2 bisects the output light P01 from the filter F1. Couplers 3, 4 branch the light advancing in linear waveguides 9, 10 to ring type waveguides 5, 6. The input light Pi; for example, 1.55mum light, is split to 2:1 by the coupler 1 and is branched to the filters F1, F2; further, the output light P01 is bisected by the coupler 2, when said light is inputted to this element. The respective temp. coeffts. of the refractive index of InP and GaAs move by 84MHz and 127MHz to the low-frequency side if it is assumed that the temp. of the element rises by 0.01 deg.C. The temp. fluctuation quantity is, therefore, obtd. by detecting the same.

Title: Variable gain amplifier
Inventor: FURUTA KOUICHI
IPC: H03G3/12
Filed: 1983-11-07
Abstract: PURPOSE:To ensure the effective gain switching by means of a logical input by using a transistor of an emitter follower which forms a feedback loop with different current value to an operational amplifier in response to the logical input and a constant current source circuit of the emitter follower. CONSTITUTION:Transistors TR Q3 and Q4 are turned off while TRQ7 and Q8 are turned on respectively in case logical inputs I and II are set at a low level and a high level respectively. Thus the emitter follower of a TRQ2 and its constant current sources Q9 and Q10 are cut off. Then the emitter follower of a TRQ1 and its constant current sources TR Q5 and Q6 are actuated. Therefore a feedback loop is formed with a resistance R and the feedback resistance Rf1 of the base emitter of the TRQ1. As a result, the gain is set at -Rf1/R1 as long as a resistance R1 is small enough and can be neglected to the Rf1. On the contrary, the emitter follower of the TRQ2 and its sources Q9 and Q10 are actuated in case logical inputs I and II are set at a high level and a low level respectively. Then the gain is set at -Rf2/R1 owing to formation of a loop including a feedback resistance Rf2.
