Patent JP-S60116015-A (JP)
Title: Current generating method
Inventor: UTSUNOMIYA KIMITAKE
IPC: G05F3/30
Filed: 1983-11-29
Abstract: PURPOSE:To generate a current proportional to absolute temperature by providing a voltage control circuit and a band gap circuit, and leading out the potential difference across a resistor constituting the band gap circuit and applying the potential difference to a resistor with an optional resistance value. CONSTITUTION:A voltage before being stabilzed is supplied to a voltage control circuit 32 from a voltage source 31, and a voltage VCC is developed at the output side of this control circuit 32. This voltage VCC is supplied to the band gap circuit 33 and a reference voltage V1 obtained by the band gap circuit 33 is fed back to the control circuit 32 to stabilize the voltage VCC. The band gap circuit 33 controls the VCC so that collector currents I1 and I2 of transistors (TR)Q1 and Q2 are equal, and equations (1)-(3) hold, where I1 and I2 are currents flowing through them, In the inequalities, R1 and R2 are the resistance values of resistors and R1/R2 has not temperature characteristics, so R3I1 is proportional to the absolute temperature. Further, R1I1 and R2I2 are proportional to the R3I1, so the voltage V2 of the band gap circuit 33 is passed through a buffer circuit 34 to lead a desired current out from the point of connection with an external resistor 35.

Abstract: PURPOSE:To shorten a bird's beak of a memory array, to extend the semiconductor element regin of the array and to increase a storage charge amount by reducing the thickness of the isolating oxide film of the array as compared with that of the isolating oxide film of a peripheral circuit. CONSTITUTION:Since inversion preventive layer of a peripheral circuit and a memory array, and isolating oxide film between elements are separately formed, the concentrations of an inversion preventive P<+> type diffused layer 4a of the peripheral circuit and an inversion preventive P<+> type diffused layer 4b of the array can be arbitrarily determined, the concentration of the layer 4b of the array is enhanced to increase a resolution capacity between the elements. Thereafter, with a silicon nitride film 3 as an antioxidation mask isolating oxide films 5a, 5b between the elements are again formed. In this case, since the film 5b of the array is formed by one time oxidation, bird's beaks are shortened as compared with those of the film 5a of the peripheral circuit formed by two time oxidations, thereby increasing an active region.

Abstract: PURPOSE:To eliminate damage and dust sticking and to array and arrange optical fibers concentrically by dipping tip parts of the optical fibers into an organic solvent and bundling the tip parts of the optical fibers before and after a process wherein an adhesive is injected among the optical fibers and cured by being heated to maintain the concentric circular state. CONSTITUTION:The coat of an optical fiber 2 nearby their tips are removed, and the coated ends are bundled in order concentrically with a thread 3 and inserted into a pipe 4. Then the tip parts of the optical fibers 2' are dipped in the organic solvent 5 and inserted into a pipe 6 in a bundle by surface tension and then the adhesive 7 is injected nearby the pipe 4, so that the adhesive permeates among the optical fibers 2' by capillarity. When the adhesive reaches a proper position, the adhesive is heated by a heater 8 to cure partially and stopped from permeating, the thread 3 and pipe 6 are removed after the adhesive cures, and the tip parts of the optical fibers are dipped again in the organic solvent 5 and cleaned with an ultrasonic wave, thereby removing sticking dust. Consequently, the optical fibers are arrayed concentrically without damaged nor dust sticking.

Title: Electronic file system
Inventor: MIURA KIYOTAKA
IPC: G06F17/30
Filed: 1988-09-09
Abstract: PURPOSE:To acquire and register the desired pictures at the remote facsimile side although an unmanned state is kept at the electronic file side by preparing a means which recognizes the states of pictures in a specific area included in the received picture information and a means which converts the states of the pictures into the specific code information. CONSTITUTION:The picture information is transmitted via a facsimile equipment 17 of the remote side for retrieval of the pictures stored in an electronic file of an electronic file system. Thus the electronic file analyzes the retrieving information out of the received picture information. In other words, the mark position of a mark sheet of the retrieving information is recognized via an image memory 11 and converted into the corresponding code data for retrieval of pictures. Thus a desired picture is read out of an optical disk 8 and transmitted. At the side of the equipment 17, a key word is written into a specific part of the picture to be transmitted based on a fixed procedure. Thus the electronic file analyzes the received picture to recognize it as the OCR characters and registers the picture with the recognized characters defined as a key word. Thus it is possible to acquire the desired pictures despite an unmanned state kept at the electronic file side and also to register the picture data.

Title: Bridge circuit for mutual connection of network
Inventor: WATANABE AKIRA
IPC: H04L12/66
Filed: 1990-08-28
Abstract: PURPOSE:To shorten the time required for a bridge on the opposite side to learn position information of a station by generating a message which has the address of the transmission source station of a received message as the transmission source station and has an ineffective destination station address at the time of receiving this message in a network where a reception destination station receives the message and transmitting this generated message to a network other than the network where the message is received. CONSTITUTION:After updating information of a station 2A in an internal memory, a bridge circuit 62 which receives the message transmits a message, which has the transmission source address as the transmission source address of the received message and has reception destination address '0' and has no information, to a network. By this operation, information of movement of the station 2A from a network A to a network C is quickly transmitted to bridge circuits in the whole of the network.

Title: Method and circuit for parallel/serial conversion
Inventor: HIRAYAMA SEIICHIRO
IPC: H03M9/00
Filed: 1993-09-13
Abstract: PURPOSE:To prevent slip from being generated at the time of conversion by starting the operation of a fixed cycle circuit with the output of a differentiation circuit and supplying a signal in a fixed cycle to a serial conversion circuit only with a clock for serial data later while suppressing the output of the differentiation circuit. CONSTITUTION:FF 21 and 22 of a differentiation circuit 2 and an AND circuit 24 input clocks (Pc and Sc) for parallel and serial data, and an FF 23 shifts a pulse obtained by differentiating the Pc with the Sc by applying delay. Therefore, a signal setting the pulse near the center of a parallel signal is counted by a fixed cycle circuit 3 while using a quatenary counter 33, and a synchronizing load signal in the fixed cycle is generated and supplied to a serial conversion circuit 1. At such a time, since the Pc and the Sc are asynchronous, outputs Q0 and Q1 of the counter 33 are ORed by an OR circuit 34 and impressed to the inverted input of an AND circuit 31, and the differentiated output is suppressed. On the other hand, before the first differentiated signal pulse to load the counter is inputted, an output stop circuit 4 stops the output of the synchronizing load signal. Thus, the slip of the circuit 1 can be prevented from being generated.
