Abstract: PURPOSE:To prevent a momentary power failure and the generation of a spark at the time of tap switching of a transformer by selecting a necessary tap unless the output voltage from a main power source is between the upper and lower limit values of a used voltage. CONSTITUTION:The upper and lower limit values of the used voltage which are necessary are previously set and an output voltage detecting means 23 detects the output voltage from the main power source; when the detected output voltage is not between the upper and lower limit values, a tap selection control means 25 selects a necessary tap. At this time, a relay switching means 37 receiving the signal of the tap selection control means 25 switches taps in order from an initial tap position and when the output voltage enters the specific upper-lower limit value range, the tap switching operation stops. Then when the taps are switched in order, the relays 9 of the respective taps are switched. Consequently, the power failure and spark generation at the time of the tap switching of the transformer can be prevented.

Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To output plural characters as a character string in a well balanced state as a whole when a plurality of characters are outputted in an arranged state. SOLUTION: Font data representing the external forms of the plurality of characters 21, 22, and 23 are arranged as the character string 20 so that the centers 21a, 22a, and 23a of the font data themselves may form a vertical line and the intervals among the characters 21, 22, and 23 may become equal to each other in the vertical direction. Consequently, the font data can be outputted as a well-balanced character string having a beautiful external appearance. In calculating the centers 21a, 22a, and 23a of the characters 21, 22, and 23, the centers 21a, 21a, and 23a of the font data themselves are calculated in disregard of the face frames 21b, 22b, and 23b of each font data or, for font data composed of left-hand side radicals and right-hand side radicals, the center of the whole font data is calculated, based on the center of each data.  Since there is such a case that a more natural external appearance can be obtained when the center lines are calculated from an envelope enveloping centers of gravities or characters, a data base is formed in advance as the supplemental knowledge corresponding to each font data.

Title: Address converter
Inventor: KIYOHARA TOKUZO
IPC: G06F12/10
Filed: 1986-01-23
Abstract: PURPOSE:To speed up an address converting time and an average address converting time including a virtual space changing-over time due to the increase in a converting logarithm by providing plural address converting buffers and an address retrieving part. CONSTITUTION:The first address converting buffer 6 compares with the virtual page number of a converting pair through a tag part 10 concerning the virtual page number of a virtual address inputted. As such a result, when the converting pair having the same virtual page number exists, the corresponding actual page number is read from a data part 11 and the actual address is prepared. For the second address converting buffer 16, the pair of the set, etc., of a virtual space identifying number and a virtual page number is used as the converting pair and used when there is not the converting pair corresponding to the buffer 6. When both buffers 6 and 16 do not have the corresponding converting pair, an address retrieving part 20 executes the converting from a virtual address to an actual address based upon the address information on a main memory. Thus, the address converting time and the average address converting time can be made highly speedy.

Title: Vacuum vapor deposition method
Inventor: KATAGAWA HIROSHI
IPC: C23C14/54
Filed: 1982-01-29
Abstract: PURPOSE:To easily control the specified proper quantity of evaporation in a vacuum vapor deposition process in which current is applied to a barlike heater wound with an object to be evaporated, by determining the quantity of evaporation from the change of conduction voltage. CONSTITUTION:For instance, in manufacturing an X-ray fluorescence multiplier tube, a Ti getter, metal to be evaporated, 2 and a spacer 3 made of W that checks flowing of the getter are wound spirally in parallel around a barlike heater 1 made of W. In vapor deposition the heater 1 is heated by applying a fixed current and the getter 2 is melted. At this time, the voltage between heater 1 terminals goes up from a point 0 to a point 4 and after dropping to a point 5, goes up again as shown by 6. The getter 2 starts to melt at the point 4 and melts further to flow into an opening between the spacer, and the voltage drops. When it is melted completely, the voltage rises. The difference in voltage between the dropped point 5 and rising part 6 is in linear relation with the quantity of evaporation. Accordingly, the specified quantity of evaporation can be controlled by detecting the difference in voltage.

Title: Device for idling up engine
Inventor: ITOU MASAMI
IPC: F02D41/08
Filed: 1979-02-08
Abstract: PURPOSE: To prevent the hunting of rotational frequency of an engine, by causing the engine to maintain an idled-up state by itself if a high pressure switch is once actuated.  
     CONSTITUTION: When a steering wheel 1 is turned to the right or left, a high pressure switch 10 is closed and a control circuit 8 retains an idling-up signal by itself and applies the signal to a throttle valve control mechanism 7. The mechanism receives the idling-up signal so that a throttle valve 6 at an idling degree of opening is pushed open by a prescribed angle by the mechanism. As a result, the rotational frequency of an engine is idled up. The idled-up state of the engine is maintained as long as the fluctuation in a load applied to a hydraulic circuit does not fall below such an oil pressure level as to actuate a low pressure switch 9. The hunting of the rotational frequency of the engine is thus prevented.
