Title: Brightness adjusting circuit of cathode ray tube
Inventor: TAZAKI KATSU
IPC: H04N5/57
Filed: 1984-06-06
Abstract: PURPOSE:To attain ease of adjusting operation by connecting a constant voltage element in parallel with a variable resistor for adjusting brightness to make a voltage generated across a variable resistor constant thereby bringing the range of change of the brightness by the variable resistor to a prescribed value at all times. CONSTITUTION:A series comprising a variable resistor 2 and a fixed resistor 8 is connected in parallel with a series circuit consisting of a variable resistor 1 and a fixed resistor 9 via a moving element 1a and a constant voltage element 7 is connected in parallel with the variable resistor 2. Through the constitution above, the resistance value of the variable resistor 1 is changed to change the voltage applied to the 1st grid 5 of the cathode ray tube 4 thereby correcting the variance of the cutoff voltage. A potential difference V28 across the series circuit comprising the variable resistor 2 and the fixed resistor 8 is changed naturally and since a potential difference V2 of the variable resistor 2 is kept constant at all times, the voltage varied by the variable resistor 2 is made constant.

Title: Code converter
Inventor: MANABE TOSHIHIKO
IPC: G06F5/00
Filed: 1984-06-11
Abstract: PURPOSE:To improve the processing efficiency of code conversion by receiving n-number of bits of a code string and discriminating whether this bit information is a code having an n-bit length or a part of a code having a 2n-bit length and holding and processing this information. CONSTITUTION:A comparator (CP)13 compares n-bit data 1 of the code string with data set to a switch 12 and outputs ''0'' to a control part 14 if the value of data 1 is smaller. When a ready signal 1 is ''1'' and data 1 is settled, the control part 14 sets data 1 to registers 15 and 16 and sets a ready signal 2 to ''1'' and outputs the same n-bit code to signal lines 108 and 109 and extends data 2 to 2n-number of bits. If the value of data 1 is equal to or larger than the value of the switch 12, the CP13 outputs ''1'' to the control part 14. The control part 14 sets the ready signal 2 to ''0'' and stores data 1 in a register 15 to use this data as upper n-number of bits of 2n-bit data and sets the ready signal 2 to ''1'' and stores data 1 in a register 16 to use this data as lower n-number of bits of 2n-bit data, and thus, 2n-bit data 2 is generated.

Title: Clearing method of accumulated data in electronic balance with accumulation function
Inventor: HASHIDO AKIYOSHI
IPC: G01G23/42
Filed: 1979-09-14
Abstract: PURPOSE: To ensure that the valuable data does not lost even when the erasure of accumulated data is erroneously instructed, by a method wherein when the erasure of the stored contents is instructed, the erasure is conducted after the stored contents are printed.  
     CONSTITUTION: When a microcomputer 1 confirms that both a switch 7 for instructing the total printing and a switch 9 for instructing the erasure of the total have been operated, it instructs total memory to read the contents of group I and instruct a printer 5 to print the contents. Then the number of the stored data of group I is read; when the number is detected to be equal to the number of printing times, the group is changed from I over to II and the contents of group II are printed. After the contents of groups III, IV and V are printed completely in a similar manner, the change-over instruction is detected for the fifth time, when the contents of the total memory are cleared and the confirmation of switches 7, 9 are released. Then the contents of the total memory are stored, and the grand total of the groups IWV is printed to complate the erasure of the accumulated data. Accordingly, the risk of losing the valuable data is obviated.

Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To suppress an address cross talk without increasing the cost of a drive system by partially overlapping a third electrode group and barrier ribs at adjacent sections in spaces having no maintenance discharge between display cells in the direction parallel with the third electrode group arranged to cross first and second electrode groups, and arranging the third electrode group in response to the monochromes of the display cells. SOLUTION: Barrier ribs 31 are formed at the angle θ against address A electrodes 29. The angle θ is set to an angle satisfying θ = arctan (Lxy/La), where La is the cell pitch in the direction of the address A electrodes 29 and Lxy is the cell pitch in the direction of X, Y electrodes 22, 23, thereby the address A electrodes 29 and barrier ribs 31 can be partially overlapped in so- called adjacent gap regions 53 having no electric discharge, and an address cross talk can be sharply reduced. The address A electrodes 29 are arranged in response to the monochromes of display cells, the color controlled by one address A electrode 29 is made monochrome, and the drive cost is reduced.

Title: Steering device for travelling vehicle
Inventor: ICHIMURA MASAAKI
IPC: B62D5/06
Filed: 1979-09-18
Abstract: PURPOSE: To drive a vehicle in the same directon with a same control operation when it is in travelling motion, by switching a selector valve, between a control valve that feeds pressure oil to a steering cylinder and an oil pressure source, in accordance with a position of the driver's seat or various states of travelling.  
     CONSTITUTION: If a switch 44 is placed to a normal travelling position, the first selector valve 24 is set to the first position and the second selector valve 28 is set to a neutral position. When a solenoid valve 21 is placed to the first position, pressure oil from a pump P2 is fed to the first chamber in a front steering valve 16F to extend a tube 16a and select a front steering valve 11 to the second position, and pressure oil from a pump P1 is fed to an extension chamber at the right side of a front steering cylinder 7 and to a contraction chamber at the left side of said cylinder, and this causes front wheels 2 to be swivelled to the right (arrow mark A) through a piston rod 7a and knuckle 17. Because a piston 16b is moved upward by the knuckle 17, the valve 11 is reset to its neutral position and the front wheel 2 is stopped swivelling at that position. Because the valve 28 is in the neutral position,  rear wheels 3 are in a state of straight travelling.
