IPC: G06F17/22
Filed: 1995-01-23
Abstract: PURPOSE: To display a word having the instructed kind of attribute by adding the kind of the word to a word in a dictionary as an attribute and designating this attribute. CONSTITUTION: When a Japanese syllabary (KANA) is inputted from a keyboard 201 by a user and KANA/Chinese character (KANJI) conversion is instructed, first of all, a CPU 206 moves to the route of the dictionary. Then, an external storage device (DISK) 208 mounting a dictionary for KANJI conversion is controlled.

Title: Duct of ventilating fan
Inventor: KISHINOUE KENICHI
IPC: F24F13/02
Filed: 1984-01-20
Abstract: PURPOSE:To enable to mount a simultaneous supplying and carrying-off type ventilating fan both vertically and horizontally even after a duct has been embedded in a wall in advance by a structure wherein the duct serving as an air passage to connect the ventilating fan and the outside of a room is formed by providing two partition plates, which partitions lengthwise and breadthwise, in the interior of the duct. CONSTITUTION:A simultaneous supplying and carrying-off type ventilating fan 1 and a duct main body 2, the air passage formed by the inside of which is divided into four air passages partitioned crosswise by partition plates 3, are provided. When the ventilating operation is performed under the state that the simultaneous supplying and carrying-off type ventilating fan 1 is mounted vertically, the foul air in a room enters the simultaneous supplying and carrying-off type ventilating fan 1 and passes through the exhaust air passage 4 of the duct main body 2 and then is exhausted outdoors. On the other hand, the fresh outdoor air passes through the supply air passage 5 of the duct main body 2 and enters the simultaneous supplying and carrying-off type ventilating fan 1 and then is supplied in the room. In this case, the supply air and the exhaust do not mix with each other in the duct main body 2, because they are separated from each other by means of the partition plates 3. Thus, even when a space is too narrow for the simultaneous supplying and carrying-off type ventilating fan to mount horizontally, the simultaneous supplying and carrying-off type ventilating fan can be mounted by locating it vertically utilizing the duct, which has already been embedded.

IPC: G11C11/407
Filed: 1987-01-20
Abstract: PURPOSE:To vary the memory capacity by using a delay element performing the first in first out operation as a memory circuit and changing the extent of delay, namely, the practical memory capacity. CONSTITUTION:LO'AD shows a load signal, INIT shows a initialized signal and CK shows a clock signal respectively. When a load signal LO'AD and an initializing signal INIT are active together, initial value '10,000,000' is set to first and second address registers. When the signal INIT is active, the output signal of the second address register is selected as the word signal and '10,000,000' is set to the word line. When the signal INIT becomes non-active thereafter, contents of the first address register are shifted left synchronously with a clock signal CK, and contents of an F/F in the leftmost position are shifted to an F/F in the rightmost position. When the signal INIT is non-active, the output signal of the first address register is selected as the word signal.

Filed: 1990-01-17
Abstract: PURPOSE:To enable the starting of operation of a display circuit and an oscillation pulse circuit simultaneously by providing a switch (electronic switch) between a power pulse train conversion circuit and a counting circuit to open or close the switch according to a voltage of a power source circuit. CONSTITUTION:An electronic switch 8 is provided between a power pulse train conversion circuit 3 and a counting circuit 4. An opening/closing control circuit 9 detects a size of a DC output of a power source circuit 7 and when the resulting detection value presents a lower unstable voltage or a higher stable voltage than a specified value, the switch 8 is operated to open or close. With such an arrangement, when a voltage of a circuit desired to measure power falls below a specified value, the control circuit 9 operates to open the switch 8 while the operation of a display circuit 5 and an oscillation pulse circuit 6 is stopped. When a circuit voltage becomes stable exceeding a specified value, the control circuit 9 operates to open the switch 8. Thus, the display circuit 5 and the oscillation pulse circuit 6 starts to work simultaneously thereby eliminating a difference between the both.
