Title: Electro-acoustic converter possessing folding diaphragm
Inventor: KISHI OSANORI
IPC: H04R9/04
Filed: 1978-12-04
Abstract: PURPOSE:To obtain a high-quality speaker for the high-pitched tone by blocking virtually the back part of the folding diaphragm via the cavity magnetic pole with groove. CONSTITUTION:Grid magnetic pole 10 in the front and cavity magnetic pole 11  with groove at the back sandwiches permanent magnet 12 between at their side adge parts, thus forming the magnetic field within the excited opposing cavities. Thus folding diaphragm 13 is held by holding frame 15 in non-contact to poles 10 and 11. For pole 10 the range partitioned by dotted line 16 features the grid form with outside radiation of radiation sound of + or -PO; while pole 11 forms comb-line groove 17 in the range partitioned by dotted line 16' to then form the cavity. Projection part 18 of pole 11 is opposed to grid 19 of pole 10, which forms the shortest cavity magnetic path with the magnetic flux density of 5-6 gauss. The cross-sectional area of each part of these magnetic poles is decided so that no magnetic saturation is caused by the inflow and pass of the main magnetic flux. Plural number of groove 17 of pole 11 are inserted in series to diaphragm 13. In this constitution, a high- quality and high-tone speaker is obtained with the wide-angle dispersion of more  than 60 deg. possible up to 15Hz on the horizontal plane.

CONSTITUTION:Raw materials (waste tires, lumber from thinning, chaff, etc.) charged into a dry distillation chamber E are successively delivered to an incineration zone F while these materials are dry-distilled on a moving incineration stoker. The raw materials are subjected to flaming incineration by fanning with a flame fanning burner 31 and are discharged as incineration ashes H from an ash discharge zone G. While the raw materials charged into a dry distillation chamber Q are dry-distilled on the moving incineration stoker, the materials are successively delivered to an incineration zone R where the materials are subjected to flaming incineration by fanning with a flame fanning burner 42. The materials are then discharged as incineration ashes H from an ash discharge zone S. The raw materials charged into a fore chamber K of the carbonization furnace are thermally decomposed and carbonized on the movable stoker movable forward and backward between the fore chamber K and post chamber L of the carbonization furnace and are discharged from a carbon discharge zone.

Title: Inverter controller
Inventor: NISHIMURA HIROMICHI
IPC: H02P27/06
Filed: 1992-06-10
Abstract: PURPOSE:To provide an inverter controller performing variable speed control of a pull rotor motor in which starting current required for releasing brake is ensured and the motor can be controlled according to a corresponding V/f pattern after release of brake by providing a start time V/f operating means which produces an output for a predetermined time after start. CONSTITUTION:Upon provision of a start command, connection is made through a switch 9 with a start time V/f operating circuit 10 which produces a preset start time boost voltage for a predetermined time after start, and the output from the circuit 10 is delivered to a PWM signal generating circuit 5 in order to ensure high starting current thus releasing brake of a pull rotor motor 11. Subsequently, connection is made through the switch 9 with a V/f operating circuit 6 operating a V/f pattern based on a preset boost voltage and a basic frequency and the output from the circuit 6 is delivered to the PWM signal generating circuit 5 thus making a transion to V/f pattern for normal operation. This controller releases brake smoothly and selects a V/f pattern suitable for the motor during normal operation.

Title: Data processor
Inventor: KOKURYO TAKUYA
IPC: G06F9/38
Filed: 1991-06-21
Abstract: PURPOSE:To decrease the stop of a pipe-lined processing generated at the time of branching according to a branching instruction by continuously executing following instructions and canceling an instruction preceding to the instruction of a branching destination even when the branching instruction is detected. CONSTITUTION:When the branching instruction is detected by a first processing means 4 to decode the instruction and the address of the branching destination is calculated by a second processing means 5 to calculate an operand address, the address is stored in a branching address register 21. For example, when a non-condition branching instruction is decided to be branched to the branching destination address by the second processing means 5 and a condition branching instruction is decided to the branching destination address by a fourth processing means 7 to execute calculation, a branch judgement part 19 detects the branch and instructs it to cancel control parts 9-13 on respective stages that a non- branch side instruction discriminated as an unwanted instruction is canceled. When it is decided that the instruction is not branched to the branching destination address, no instruction is canceled, and the pipe-lined processing is continuously advanced as it is.

IPC: G06F17/50
Filed: 1991-06-21
Abstract: PURPOSE:To easily grasp and correct the logic of a circuit diagram by arranging the generated symbols in the circuit diagram based on the connection information and the importance of the connecting relation among the symbols. CONSTITUTION:A retrieving part 3 retrieves the symbol name that is connected to the largest number of circuit symbols based on the connection information stored in an information store part 1. An arrangement position calculating part 4 generates a symbol A corresponding to the retrieved symbol name and calculates the arrangement position of the symbol A in a circuit diagram to arrange it. Then the part 3 retrieves a symbol name with which all output lines or input lines are connected to the symbol A only based on the connection information stored in the part 1. Then the corresponding symbols B0-B2 are produced at the part 4. The part 4 arranges the symbols at positions close to the symbol A starting at a symbol B2 having the largest connection number so that the input signals flow successively to the right from the left in the circuit diagram. The arranged symbols and the arrangement positions are shown at a display part 5.

Title: Fuel injection type spark ignition internal combustion engine
Inventor: HOTSUTA KAZUHITO
IPC: F02M67/02
Filed: 1997-05-24
Abstract: PROBLEM TO BE SOLVED: To correctly inject a small amount of fuel in response to the operating state into a combustion chamber from a fuel injection nozzle by introducing pressurized fluid at low pressure into a fuel pressure regulating means when an engine is operated at low load and low speeds and by setting the pressure of the fuel at low pressures. SOLUTION: If an internal combustion engine 1 starts and is at a low load operation state such as idling operation, the pressure in pressurizing gas chamber 17 is increased above the atmospheric pressure and a piston 47 is moved to the left by the pressure in the high pressure diaphragm chamber 46 of a variably pressurizing unit 43. Therefore, a port 49 is closed by the piston 47 and the pressures in a low pressure diaphragm chamber 45 and the diaphragm chamber of a pressure regulator 25 are fluctuated by the variable pressure in the pressurizing gas chamber 17. The pressure in the diaphragm chamber of the pressure regulator 25 is held at nearly atmospheric pressure and fuel is injected at relatively low pressure from a fuel injection valve.

Title: Mark reader
Inventor: IWAI HAJIME
IPC: G06K7/015
Filed: 1988-06-17
Abstract: PURPOSE:To improve mark detecting accuracy by supporting a holder or a supporting roll in a state to be optionally reciprocated and excited to the opposite direction. CONSTITUTION:In case of reading out a mark sheet 13 by an optical sensor 33, the rear face of the sheet 13 is supported by the supporting roll 39 and its surface is pressed by a sheet pressing part 40 of the holder 34. When wrinkles or warps are generated on the sheet 13, the wrinkles or warps are spreaded by the pressure of the holder 34 or the roll 39 because one of them is excited to the opposite side. Thereby, a distance between the sensor 33 and the sheet 13 is always held at a fixed value. When the thickness of the sheet 13 is changed, one of the holder 34 and the roll 39 is displaced and absorbs a change in the thickness, so that the distance between the sensor 23 and the sheet 13 can be similarly held at the fixed value. Thereby, mark detection can be always accurately executed and the mark detecting accuracy can be improved.
