Title: Electric power supply of fluorescent lamp for wide area operation and control circuit
Inventor: JIEEMUZU EMU UIRIAMUZU
IPC: G02F1/13357
Filed: 1995-03-16
Abstract: PURPOSE: To provide an apparatus and a method for driving on a fluorescent lamp by a low-voltage DC power source. CONSTITUTION: A DC-AC inverter 20 converts a low-voltage DC into high- voltage AC for driving on a fluorescent lamp. The lamp is included in a feedback loop comprising a circuit 30 for generating a feedback signal showing the intensity of the electric current to be applied to the lamp. Alternatively, the lamp is insulated from a drive circuit to indirectly draw out the feedback signal to drive symmetrically. The feedback signal is applied to a switching regulator 25 to produce adjusted electric current in the lamp and consequently to produce adjusted lamp light intensity. The intensity of the lamp current is adjusted, and the intensity of the light of the fluorescent lamp covers from a practically completely off-state to a completely on-state and the intensity is adjusted over the selected range of the light intensity so as to fluctuate smoothly and continuously.

Title: Image forming device
Inventor: EZU AKIHIRA
IPC: G03G15/04
Filed: 1989-03-13
Abstract: PURPOSE:To most effectively cool the overall surface of an original platen and to improve availability by mounting a cooling means near a carriage with which it is moved. CONSTITUTION:The cooling means 7 consists of a fan 71 mounted near the first carriage 23 having an exposure light source 21 and a vent hole mounted on a main body frame 1 on the rear side of the fan. Although the fan 71 is integrally reciprocated with the first carriage 23, its rotation is stopped while an exposure light source 21 is lighted and scans in view of an adverse effect caused by an oscillation. When the fan 71 is conversely returned, it is operated and moved so that the original platen 11 is blown and cooled by an air current. Then the fan is returned to an ordinary position and the operation is continued even while the carriage is stopped. Thus the original platen 11 is most effectively cooled. Therefore, the device can tolerate continuous operation for a long time and the availability is heightened.

Title: Error correction processing method
IPC: H04B14/04
Filed: 1992-03-16
Abstract: PURPOSE:To prevent the abnormal sounds caused by the voice reproduction of the wrong data by forcibly interpolating and processing the error flag value to logical value 1 when the conditions of an error flag pattern are satisfied against the occurrence of an uncorrectable error. CONSTITUTION:It is decided that the condition 1 is satisfied and M1 pieces of error flags are all set at logical value 1 when N1 or more pieces of error flags of logical value 1 are included in M1 pieces of error flags which are continuously stored. Thus the signal of logical value 1 is inputted to one of both terminals of an OR circuit 36 through a Q output terminal of an FF 35 when the condition 1 is satisfied. Therefore all error flags taken out of the circuit 36 are equal to logical value 1 regardless of the value of the error flag inputted to the other terminal of the circuit 36 from an FF 310. In such a way, the value of the error flag is forcibly changed into logical value 1 in an interpolation processing state. Thus it is possible to prevent such a case where no error is decided and an abnormal sound is generated when many errors are included in the data.
Patent JP-H11261465-A (JP)
Title: Radio communication system
Inventor: OKA MINORU
IPC: H04B7/15
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To attain relay radio communication with high reliability against a communication fault by generating plural transmission data packets for relaying to a next stage with no error data integrated to them, transmitting the packets continuously to a radio relay station or a radio reception station, and allowing the station to select the no error data and to use the data as reception data. SOLUTION: In the case of receiving a 1st packet 1/4 among four data packets sent continuously from a master M, the station S1 receives a total consecutive transmission number 4 and a transmission sequence number 1 written in the packet, sets a time required to receive three succeeding packets to a reception watchdog timer of its own station and starts the timer. In the case that the data packets 2/4,3/4 are received but the packet 4/4 does not reach due to a communication fault, when the received data packets 2/4 and 3/4 are normal, the station S1 integrates them to generate transmission data packets 1/4-4/4 for relay to a next stage, sends the packets to a next stage radio reception station S3. The station S3 sets the time to its reception watchdog timer similarly to the case with the station S1 corresponding to the normal data and receives the data.  Thus, the transmission efficiency is enhanced by revising the time setting in this way.

Title: Load converter
Inventor: TAKAHAMA HISATAKA
IPC: G01G9/00
Filed: 1983-04-01
Abstract: PURPOSE:To make it possible to stretch an output line around together with a heavy-current wiring and to protect said line from the effect of outside noise by a construction wherein a controlling piece for the quantity of passing light is provided between first and second optical fibers so that the quantity of light may be varied by the movement of the controlling piece in accordance with a load. CONSTITUTION:First and second optical fibers 7 and 8 are retained in an intermediate unit 9 so that they face each other, and a pinhole plate 18 fixed to the cover body of a cell block 1 is inserted between the optical fibers 7 and 8, while a light source and a light receiver are connected to the other ends of the optical fibers 7 and 8 respectively. When a load G does not act on the cell block 1, the entire quantity of light falls on the optical fiber 8 through a pinhole 27. When the load G acts thereon, the plate 18 moves in accordance therewith, and thereby the quantity of light is varied. This change in the quantity of light is detected by the light receiver and converted into measured weight data. According to this construction, the emission side of the optical fiber 8 is neither subjected to induction even when it is stretched around together with a heavy-current wiring, nor affected by outside noise.
