IPC: H03M13/00
Filed: 1979-11-08
Abstract: PURPOSE: To increase the detection accuracy for the error of the reading data, by giving a comparison between the value summed up through the inspection circuit at a certain part of each record and the accumulated value during the writing and recorded on the memory in case the recorded file data is read.  
     CONSTITUTION: The file data FD sent from the buffer circuit 1 is sent to the switch circuit 9 via the output terminal (a) of the selection circuit 6 and recorded to the file memory circuit 5 via the writing circuit 3. When reading, the data FD read in precedently is read by the reading circuit 4 and sent to the circuit 1 through the terminal (a) of the selection circuit 6'. In this case, the data group (aWz) to be inspected is sent to the inspection circuit 7' via the output terminal (b) of the circuit 6' to receive an inspection, and the result of this inspection is accumulated SM' in the accumulator 8'. Then a comparison 10 is given between the accumulated  value SM' and the accumulated value SM during the writing and sent from the  output terminal (c) of the circuit 6'. And the error detection signal NG is delivered  when no coincidence is obtained through the above comparison. As a result, the  detection accuracy can be increased for the error of the reading data.

Title: Automatic ventilation fan
Inventor: MORI KEIICHI
IPC: F24F11/00
Filed: 1982-08-20
Abstract: PURPOSE:To provide the titled fan adapted to start operating automatically upon a lowered oxygen concentration in a room, by arranging such that the ON and OFF control of motor is effected by signals outputted from an oxygen sensor detecting the oxygen concentration in the room. CONSTITUTION:Potentials (a), (b) are inputted to the input terminal of comparator 18, as an oxygen sensor 7 holds no electromotive force while an oxygen concentration remains normal (21%) in a room. Upon the oxygen concentration being lowered, the oxygen sensor 7 starts generating an electromotive force, while the potential a' at positive input terminal of comparator 18 drops lower than the potential a. At the moment when there is established a relation between potentials as a'<b, the output is lowered for actuating a relay 19. In this manner, a contact 19' is energized for rotating a fan motor 6 to start ventilating. As the oxygen concentration increases, the output from oxygen sensor disappears and the comparator 18 generates a high output power for thereby rendering the fan motor 6 inoperative again.

Title: Method and system for reducing chirp in optical communication system
Inventor: DEITORITSUHI MAAKIYUUZU
IPC: H04B10/18
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To reduce chirps in an optical communication by a method wherein the transition time of a pulse in an information signal, which is fed to a modulator, is shortened. SOLUTION: A wide-band width driver 110 drives a modulator 130 for sending a modulated light signal 135 to a fiber transmission system 140. The driver 110 itself is independently used or the driver 110 is used in combination with the wide-band width modulator 130. In this case, when the transition time of a pulse is decreased, chirps in the modulated signal, which is propagated along a dispersion optical medium, are decreased. Accordingly, the driver 110 for decreasing the transition time of a pulse in a drive signal sent to the modulator 130 decreases the transition time of the pulse in the modulated light signal 135. Thereby, the chirps in an optical communication can be reduced.

Title: Water supply and drain system for water cooling pallet in sintering apparatus
Inventor: NOSE MASAYUKI
IPC: F27B21/08
Filed: 1977-12-02
Abstract: PURPOSE:In a circular type sintering apparatus, a plurality of rotary pallet is water- cooled to prevent lowering of yield strength and hardeness of the body and thus to minimize or eliminate deformation and abrasion of pallet at a high temperature. CONSTITUTION:A plurality of pallets 1 is circularly and endlessly connected each other to form a circular pallet group 2. At the upper and lower portion of inner side of the pallet group 2, a cooling water header 29 and a drain header 31 are installed. At the center of the pallet group 2, a fixed column 23 is installed. Cooling water is passed through feed pipe 41 of the fixed column 23, conduits 27, the cooling water header 29, short conduits 30 and all pallets 1. The cooling water is supplied from an inlet 10A of a spiral conduit into the pallets 1, whereby the water cools  vertical frames 4A and 4B and horizontal beams 5A-5E. The water is exited from  an outlet 10B and passed through a flexible tube 32, the drain header 31, drain conduits 28, annular conduit 26, and exhausted through drain 42. The water system thus cools the pallet and effectively prevents a high temperature deformation  and abrasion thereof.

IPC: B60T7/08
Filed: 1995-05-19
Abstract: PURPOSE: To prevent braking operation from being forgot by projecting a parking brake lever toward a getting on/off passage to a driver seat so as to prevent a driver from leaving the seat when the parking brake lever arranged on a getting on/off side of the driver seat is operated in the brake releasing direction. CONSTITUTION: A driver seat 7 is supported so that its direction can be changed around an axial line of a driver seat base 6, and base ends of a brake lever 12 is mounted in both outside ends of a lever supporting shaft 11 passed through a stepped expanded diameter part 8 in the seat base 6. When the parking brake lever 12 is operated to a brake releasing position P1, a part from a intermediate part to the tip part in the parking brake lever 12 is projected toward a getting on/off passage 30 in front of the driver seat 7, so that the driver is prevented from leaving the driver seat 7. Therefore, the operation of a parking brake can be prevented from being forget in leaving the seat.  As the parking brake lever 12 is switched in the longitudinal direction integrally with the driver seat 7, the operating direction is kept in the same direction even if the driver seat 7 is directed in any direction, so that operation is facilitated while erroneous operation can be prevented.

Title: Method and device for processing image
Inventor: MATSUBAYASHI KAZUHIRO
IPC: G06K9/03
Filed: 1991-06-18
Abstract: PURPOSE:To attain more developed image processing by preparing two kinds of deleting means for deleting a character as a recognition result of inputted image information and then controlling the priority of the deleted character in the succeeding recognizing processing. CONSTITUTION:When a character recognizing means 4 outputs plural characters as candidates, a priority order ascending means 6 ascends the priority and a priority order descending means 6 descendes the order. When a character correcting/erasing command is generated, a character correcting/erasing means 7 erases the characters and registers the characters in the means 6. A position correcting/erasing means 8 erases the characters when a position correcting/ erasing command is generated and registers the characters in the means 5. At the time of correcting the characters as the recognition results of image information inputted from an input device 1 after temporarily deleting them, the priority of the deleted characters is controlled in accordance with the sorts of deletion. Consequently the weight of the deleted characters to be changed in accordance with the purpose of deletion can be utilized for the succeeding recognizing processing.
