Title: Incoming direction transmission timing decision system for star type optical subscriber system
Inventor: EDA MASAHIRO
IPC: H04B10/272
Filed: 1993-05-12
Abstract: PURPOSE:To reduce the system build-up cost, to decrease a guard time for incoming communication and to improve the efficiency of communication by deciding an incoming data transmission timing based on a result of distance measurement between an exchange station and each subscriber. CONSTITUTION:An exchange station 1 sends a pulse signal to each of subscribers 31-3n and each of the subscribers 31-3n sends back the pulse signal to the exchange station and a phase comparator 8 of the exchange station compares the phase of the pulse signal sent by itself with the phase of the received pulse signal to detect a phase difference. Then a counter 12 and a coding circuit 11 calculate the distance between the exchange station and each subscriber based on the phase difference and to calculate a transmission timing of a corresponding incoming signal. In the case of usual data communication, the exchange station utilizes outgoing communication to send the transmission timing information to each subscriber and each subscriber sends incoming data for the exchange station based on the transmission timing information.

IPC: G05B15/02
Filed: 1979-08-29
Abstract: PURPOSE: To secure a conversion into Boolean algebra equation just through the input of both the contact information and the branch information of the ladder circuit, by storing successively the branch symbols of the ladder circuit and then giving the degeneration process.  
     CONSTITUTION: The ladder circuit is decomposed into the contact symbol and the branch symbol and then supplied to the branch symbol selecting circuit 2 as well as to the 2nd memory 6 via the input terminal 1. And the branch symbol selected through the circuit 2 is stored in the 1st memory 6. Then the branch degenerating circuit 4 carries out a degeneration process based on the combination of the branch symbols read out of the memory 3 as well as the combination of the contact symbols given from the memory 6. With repetition of this process, no branch symbol exists any more within the memory 3. And thus the ladder circuit can be converted into the Boolean algebra equation. In such way, a simple conversion is possible into the Boolean algebra equation just by supplying both the contact information and the branch information of the ladder circuit.

Title: Semiconductor integrated circuit
Inventor: TAKAHASHI NAOYA
IPC: G06F21/79
Filed: 1987-05-06
Abstract: PURPOSE:To prevent the surreptitious use of software by holding the contents of a ROM after converting them into such a form that is not readable as it is. CONSTITUTION:A write signal is supplied to a register 6 from a write signal input terminal 13 and data (variables a0-a3) are loaded from external terminals 2-5 synchronously with the write signal into a register 6. Hereafter a microcomputer supplies addresses to a ROM 1 via address signal lines 14-17 and works while reading successively the data (variables x0-x3) stored in the ROM 1. However the variables x0-x3 received from the ROM 1 show the normal instructions and data only when an exclusive OR is secured against the variables a0-a3 received from the register 6. Thus it is not possible to know the contents of the data stored in the ROM 1 as long as the values of variables a0-a3 are unknown.

Abstract: PURPOSE:To contamination inside of the device and at its periphery by providing a heating element at the position that the folded part of a seal member abuts on when a toner cartridge is mounted completely and providing a projection member which is energized upward by an elastic body at the position where a 2nd chamber is positioned. CONSTITUTION:When the toner cartridge 1 is mounted completely on the toner supply device 2, a microswitch 25 is turned ON and a ceramic heater 22 generates heat instantaneously to raise the temperature of the deposition part of the seal member 8 to its fusion temperature. At this time, the folded part of the seal member 8 abuts on the ceramic heater 22. Consequently, the force which is obtained by a compression coil spring 24 to press up the projection member 23 becomes larger than the deposition force of the seal member 8. Then the seal member 8 is peeled and its majority is pressed in the 2nd chamber 10 by the projection member 23 to supply toner 6 to a copying machine main body through a 1st opening 7 and a toner supply opening 21. Consequently, the contamination inside of the device and at its periphery is eliminated.

Abstract: PURPOSE:To obtain an optional stable offset voltage subjected to temperature compensation by setting resistances connected to a pair of differential transistors(TRs) to different values and providing a difference in the junction areas of the pair of differential transistors. CONSTITUTION:The titled circuit is constituted by giving a difference to the resistance of emitter resistors R1, R2 connected to the emitter of TRs Q1, Q2 (e.g., R1>R2) and giving a difference to the junction area of the TRs Q1, Q2 {e.g., Se(Q1)>Se(Q2); Se is a junction area}. Through the constitution above, a TR Q11 is bypassed via a base-emitter of TRs Q10, Q11. Thus, the base-emitter voltage {VBE(Q11)} of the TR Q11 is generated and a current {VBE(Q11)/R3} is supplied from the collector of the TR Q10 to the collector of the TR Q9. Then nearly the same current as the collector of the TR Q9 flows from the collector of a TR Q8 as a bias current I1 of the differential amplifier.

Abstract: PURPOSE:To provide both of deodorizing effect and effect for keeping the freshness of food and to keep these effects over a long period of time, by receiving porous particles, which are formed by mixing a fine powder of natural radioactive mineral with a binder, in a bag made of a nonwoven fabric. CONSTITUTION:Porous particles 1 containing a fine powder of a natural radioactive mineral are received in a bag 2 made of a nonwoven fabric. Whereupon, a very small amount of radioactive rays are always emitted from the natural radioactive mineral contained in the particles 1 and the advance of spoilage is suppressed by the ionizing action due to said radioactive rays or the action of secondary radiation and the freshness of perishables is kept and the generation of a malodor is prevented. Since the half-life of the radioactive rays from the natural radioactive mineral is long, the above mentioned freshness keeping effect and deodorizing effect continue over a long period of time. Since the action of radioactive rays is utilized, it is unnecessary to receive the particles 1 in a case having vent holes and, by receiving the particles in the bag 2 made of the nonwoven fabric, cost is reduced.
