Abstract: PURPOSE:To facilitate the assembling work, and also, to attain a miniaturization by providing a fan unit with a delimiting plate having a flow hole of exhaust air between an exhaust air side of a fan and a motor, integrating an inverter circuit and a control circuit on one integrated circuit board, and installing it in a casing. CONSTITUTION:In a control/driving integrated circuit board 10, a switching element 101 and a diode 102 for constituting an inverter circuit of three phases are installed. They are integrated into one package 30, and also, since a semiconductor element for standing a high voltage is used, it is unnecessary to allow a high voltage DC obtained by a rectifying circuit 110 to drop to a DC of a lower voltage. As a result, the circuit is miniaturized remarkably. Also, air inhaled from a suction port 20 of a casing 2 is compressed by a fan 3, passes through a diffuser 8, goes into a motor chamber from a hole part of a delimiting plate 9, passes through an exhaust port 21 and is exhausted. In this case, the package 30 is cooled by an air flow since it is installed in the vicinity of the exhaust port 21.

IPC: G06F13/38
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a data buffer of high performance with simple control by providing two buffer memories and an access control register which stores one of both buffer memories to which data are written for each address so that both data writing and reading jobs are possible at one time. CONSTITUTION:When data are read out of buffer memories 2 and 3 via a buffer circuit, one of both memories 2 and 3 to which data are written is known with reference to an access control register 13. This information on said buffer memory is set at access control bit 14. Then data are read out of the memory 2 or 3 based on the value of the bit 14. When data are written into both memories at one time, the data are written into the memory 2 or 3 to which no reading instruction is given from the bit 14 and the corresponding bit of the register 13 is replaced. In such a way, both data writing and reading jobs can be carried out at one time.

Title: Character erasing method for prepared document
Inventor: ISHIKAWA YUJIRO
IPC: G06F17/24
Filed: 1994-03-23
Abstract: PURPOSE:To provide the character erasing method for prepared document which can be considerably contributed to operability by efficiently performing erasing work by automatically and selectively using both of the functions of normal pre-erasing at the time of continuous inputting and the erasing of a character on a cursor at the time of editing only by operating one kind of erasing key. CONSTITUTION:When the erasing key is depressed (n3: YES) and there is a character on the cursor (n5: YES), one character on the cursor is erased (n6), the respective characters of a text on the right side of the cursor are shifted to left for one character (n7) and a mode is turned to 'erase' (n8). When the erasing work is repeated and there is no character on the cursor (n5: NO), the mode is switched to 'pre-erase' (n1) and when there is a character on the left side of the cursor (n10: YES), the character on the left side of the cursor can be continuously erased (n11).

Title: Image forming apparatus
Inventor: TANIMOTO YASUFUMI
IPC: H02P8/00
Filed: 1990-03-05
Abstract: PURPOSE:To prevent fluctuation of rotation or vibration by periodically varying the time interval for switching the excitation of an exciting winding according to the fluctuation of speed of a step motor. CONSTITUTION:When a step motor S is operable, excitation pattern data is read out from a ROM 351 and fed to an output register 356. An excitation register 359 latches the content of the output register 356 based on a latch signal and sets a corresponding excitation time in a timer. An excitation circuit 306b switches the excitation winding according to thus set excitation time. Consequently, inherent speed fluctuation of the step motor S can be canceled by the speed fluctuation due to the fluctuation of pulse rate. When the step motor S is stopped, stopping operation is performed at the end of the period of the excitation pattern data stored in the ROM 351 in order to enable accurate starting next time.

Filed: 1992-03-11
Abstract: PURPOSE:To selectively form a so-called silicide only in a desired element region without a need for adding a special process regarding a semiconductor integrated circuit which utilizes the so-called silicide which is generated by a selective reaction between a silicon substrate and a titanium film or the like. CONSTITUTION:For example, a sidewall insulating layer 7 is formed in a prescribed region in which a silicide is to be formed; at the same time, the insulating layer is left in such a way that other regions in which the silicide is not to be formed are covered. When a titanium film 8 or the like is deposited in this state, the silicide 8A is formed only in the prescribed element region. The titanium film or the like which is not reacted in the element regions can be removed selectively by an etching operation.

Filed: 1988-03-04
Abstract: PURPOSE:To easily fix an elevator mechanism to a reproducing position when a cassette deck is transported by equipping the title protector with a part to be detected which is detected by a detecting means, a projecting part to project from an inserting hole to an external part under the inserted state of the part to be detected, and a fixed part to be fixed with the elevator mechanism under a reproducing state and the other mechanisms. CONSTITUTION:An inserting part 2 is equipped with the function of the part to be detected and that of the fixed part, and when the part to be detected is inserted into a cassette inserting hole 9 of the cassette deck, and the inserted part to be detected is detected by a detecting means 11, and elevator mechanism 10 is moved and fixed. On the other hand, accompanying the moving of the elevator mechanism 10, the fixed part is fixed with the elevator mechanism 10 and the other mechanisms. Since a projecting part 3 is projected from the cassette inserting hole 9 under the state, the movement of an elevator can be confirmed, and a cassette half is never erroneously inserted into the cassette inserting hole 9. Thus, the elevator mechanism 10 can descend by inserting the inserting part 2 of a protector 1 into the cassette inserting hole 9, and the elevator mechanism 10 can be fixed to the descended position.
