Abstract: A photovoltaic system includes a pole member which stands on an installation surface, a connecting support member disposed on an upper end section of the pole member, a rail member supported by the connecting support member, and a photovoltaic cell module disposed on the rail member, wherein the pole supporting member includes a lower section that covers at least a portion of an outer peripheral surface of the upper end section of the pole member.

Abstract: A solar cell device includes first and second solar cell arrays disposed side by side in one direction and each including solar cell modules disposed side by side along a direction inclined with respect to an installation surface and a holding member holding an outer circumference of each of the solar cell modules. The solar cell device also includes a support member disposed between the first solar cell array and the ground and extending from the first solar cell array to the ground. In the first solar cell array, a part of the holding member positioned on the upper side in the inclined direction is fixed to the top portion of the support member, and in the second solar cell array, a part of the holding member positioned on the lower side in the inclined direction is fixed to a side portion of the support member.

Abstract: An ingot I made of a light alloy is produced using a continuous casting apparatus including a cylindrical water-cooled casting mold which is disposed immediately below a spout having an upward-turned molten metal receiving port and a downward-turned molten metal outlet, and which has an inside radius r1 larger than an inside radius r2 of the molten metal outlet, and lubricating oil discharge passages provided below the spout to supply a lubricating oil to between the water-cooled casting mold 13 and a molten metal m brought into contact with the water-cooled casting mold. In this production, a lubricating oil having a vaporization rate of 30% or more at 300° is used, and an annular gas accumulation for spacing the molten metal apart from outlets of the lubricating oil discharge passages is defined below an annular protrusion of the spout by vaporization of the lubricating oil.

Abstract: A personal portable computer system includes peripheral devices such as a printer and a CRT which can be driven by a battery power source. The computer system includes a computer body which contains interface units and power supplied to the interface units is controlled. The interface units are used for supplying power to the peripheral devices.

Abstract: A programmable electronic calculator operates in a programming mode, wherein a desired optional program is introduced into the programmable electronic calculator, or in a run mode wherein the stored program is executed. The introduced optional program is stored in a read/write memory (RAM). A mode selection switch is provided on a keyboard for selectively placing the programmable electronic calculator in the run mode or the programming mode. When a lock command is introduced through the keyboard, the mode selection switch is disabled so that the programmable electronic calculator will not be placed in the programming mode, thereby protecting the optional program stored in the read/write memory (RAM) from being unintentionally erased.

Abstract: A display device for a programmable electronic calculator comprises an input device for inputting the contents of a display to be displayed in the display device, a sheltering display memory for storing the contents of the previous display for sheltering when the display device is adapted to provide a new display, and a circuit for extracting the contents of the sheltering display memory so that the display device displays the contents sheltered, again.

Abstract: An electronic-type computer in which programs may be entered from a key entry device into a Random Access Memory in which they are stored, and those programs may be read out from the contents of that Random Access Memory and executed, while, in addition, programs may be written and stored ahead of time in a Read Only Memory, and those programs may be read out from the contents of that Read Only Memory and directly executed. The previously written and stored programs in the expandable ROM do not utilize the RAM user program area, and the large volume of programs contained within the expandable ROM can be directly executed. In addition, the user programs and the programs in the expandable ROM may be linked together and executed. Furthermore, it is unnecessary to give instructions for the programs in the expandable ROM to be transferred to the RAM.

Abstract: A programmable electronic calculator includes two cassette tape recorders as peripheral system. An optional program or a data processed by the programmable electronic calculator is introduced into and recorded on a first cassette tape recorder. The first cassette tape recorder reproduces the optional program recorded therein upon request from the programmable electronic calculator. A second cassette tape recorder carries an audible message for operation guidance purposes. An interface circuit is provided in the programmable electronic calculator for independently controlling the operation of the first and second cassette tape recorders.

Abstract: An electronic hand-held memory device is capable of containing character information and numerical information stored together as a pair. Either or both types of information may be outputted, and the numerical information may be used for calculation. Loading and fetching of character information and numeral information are performed upon actuation of keys. The desired key in effect acts as a memory key during a numeral information calculation mode. The desired key may serve as a constant memory key or a memory total key. When printing an output is desirable, the beginning of the character information is aligned with the most significant digit position and the end of the numeral information is aligned with the least significant digit position of a printer.

Abstract: An electronic device with a dot matrix display panel capable of displaying characters, symbols or other patterns is implemented with a central processing unit (CPU). When the length of the characters, symbols and other patterns is in excess of the capacity of the display panel, those intelligence signals are sequentially shifted on the display panel and preferably dot by dot.

Abstract: A display device capable of selectively displaying numerical information or character information. During the mode wherein mainly characters are processed, a specific symbol (for example, a cursor symbol) is shifted digit by digit upon each actuation of a specific key (for example, a cursor key) and a character corresponding to the symbol display is also shifted. During the mode where numeral information is processed, on the other hand, numeral information or character information associated with said numeral information is selectively displayed upon actuation of the above specific key.
