Title: Controller for inverter
Inventor: SEKI HITOSHI
IPC: H02M7/48
Filed: 1984-10-11
Abstract: PURPOSE:To eliminate the application of an excess voltage to a drive controller by detecting an overcurrent by a current detector connected in series with a main circuit self-extinguishing element, and electrically separating by the detection signal the drive controller and a main circuit. CONSTITUTION:A DC power source 4 supplies energy through a current detector 3 to an inverter 1. A drive controller 5 converts a control signal applied from a controller 5 to a signal for driving the inverter 1, and supplies a control signal through a switching element 8 to the inverter 1. If a malfunction occurs in the inverter 1 and a DC power source 4 is shortcircuited by the inverter 1, an overcurrent is detected by the detector 3, the detection signal is applied to the controller 6, and an inverter drive signal is interrupted. The overcurrent detection signal is applied to a switching element controller 7 to interrupt a switching element 8.

Title: Continuous casting method
Inventor: KOMIYA TOSHIAKI
IPC: B22D11/117
Filed: 1981-12-30
Abstract: PURPOSE:To decrease inclusions considerably and to obtain ingots having high quality  in high yields by locating the position of the discharge port of a ladle nozzle nearer the  bottom surface than the height of a gate near the striking part of the charging flow of  the molten steel in a tundish. CONSTITUTION:In the starting stage of charging of molten metal from a ladle, charging flow 11 passes through a nozzle 2 provided in the bottom part of the ladle, enters  a tundish 3 and stagnates in the part partitioned by a gate 5. In this stage, the discharge port of an expansion nozle 9 dips in the molten steel before the molten steel goes beyond the gate 5; thereafter, the melt surfaces rises and the charging flow is  thoroughly isolated from air until the melt level arrives at above the opening at the  bottom end of the charging nozzle 2, whereby the oxidation of the molten steel by air  is prevented. In the stage of continuing charging from the ladle in consecutive continuous casting, a nozzle 9 melts away already, and the slag in the position where the  charging flow of the next molten steel falls on the melt surface is removed with a gas  injecting device using a gas blow nozzle for discharging of slag, then, the charging  from the nozzle 2 is started. The flow 11 contacts with the contact part 4 and the gate 5 and produces ascending flow. The ascending flow discharges the slag on the top surface of the molten steel outward.

Title: Fixing device
Inventor: SEKIGUCHI HIDEAKI
IPC: B41J29/00
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent partial trouble in image quality occurring because an image on a recording sheet is touched by a sheet peeling member or a pair of discharge rolls and the like by disposing the sheet peeling member being a plate-like member in parallel with a heating roll and providing a means for cooling the sheet peeling member. SOLUTION: The leading edge of the recording sheet P somewhat separated from the surface of the heating roll 1 is fed to a downstream side in a state where it goes along the lower surface of the plate-like member being the sheet peeling member 6. With this as a start, the sheet P fed out from a press-contact part N is surely peeled from the surface of the roll 1. Though the sheet P just after the fixation is in a high temperature state near to fixing temperature, it is cooled by passing while touching the vicinity or the lower surface of the cooled plate-like member being the member 6. The heat of the plate-like member is efficiently radiated by a radiation fan, so that the image is more surely cooled.

Abstract: PURPOSE:To attain parity check with a 1-bit parity check memory by processing a rewritten and a non-rewritten data as if all bit width were fetched from a data bus to a local bus to detect an error in 1-bit. CONSTITUTION:When a data full bit width is rewritten, a write cycle is executed and a1 bit data is fetched to local buses 3, 3' via 2-way buffers 2, 2' in charge of each share. Then the parity check is made to each bit data by 1st and 2nd parity generators 7, 7' and 8, 8' in one-bit. On the other hand, part of bits are rewritten with respect to the data full bit width in the read modify write cycle. The data for rewritten bits is fetched to the buses 3, 3' via the buffers 2, 2' and non-rewritten bit data are stored once in latches 5, 5' from relevant memories 4, 4'. Then the bit data are fetched in the buses 3, 3' as if all data bit width were fetched from the bus 1 to the buses 3, 3' and error is detected in one bit.

Title: Origin detecting device
Inventor: YAMASHITA TAKAHIKO
IPC: G05B19/18
Filed: 1987-08-27
Abstract: PURPOSE:To quickly and accurately detect an origin by performing the detecting operation at a high speed in the range other than a part of a range from a temporary origin detection position to a zero phase signal detection position and always performing the search operation in one direction. CONSTITUTION:The detecting operation is performed at a high speed in most of the range from a temporary origin detection position (d) or (e) to the zero phase signal detection position except the range from an origin search start point (g) to the zero phase signal detection position. Even if there is a probability that a zero phase signal as the search object is in the direction opposite to a prescribed search direction because the position of a temporary origin signal or the temporary origin detection position (d) or (e) is displaced, the origin search start point (g) is moved in the fixed search direction by a prescribed extent. The zero phase signal is not detected through it is placed in this extent, and the leading edge of the next detected zero phase signal is defined as the origin detection position. Thus, the origin is quickly and accurately detected.

Title: Semiconductor laser
Inventor: NAKAZAWA NORIHITO
IPC: H01S5/00
Filed: 1991-07-29
Abstract: PURPOSE:To obtain a high-output semiconductor laser by providing beforehand a semiconductor substrate with a step structure where laser output passes through a clad layer having a band gap energy larger than that of an active layer and by forming a window structure where laser light is not absorbed in a vicinity of an end face. CONSTITUTION:An n-type GaAs substrate 1 is provided with a groove 7 before epitaxial growth so that a step 6 may develop. This groove is stripe-shaped along the resonator direction and has its end inside of a resonator end face. The step 6 provided on the substrate 1 in a vicinity of the end face causes laser light in an active layer 3 to pass through a clad layer 2 having a large band gap energy in a vicinity of the end face when advancing straight to output toward the end face. This makes a window structure to which laser light is not absorbed. Therefore, optical damage is prevented, and it is possible to increase the output of a semiconductor laser.

Filed: 1981-12-29
Abstract: PURPOSE:To obtain a high-reliability output circuit, by outputting a signal to a transmission destination only when the output signal from a transmission source has a certain relation to one of data groups corresponding to preliminarily stored transmission destination codes. CONSTITUTION:When a CPU 3-3 detects an accident of a power system, a protection command is generated to external devices. At this time, when an address detecting element 3-7a detects an address signal designating an output circuit 3-7 on an address bus 3-8, an input gate element 3-7b is opened, and the circuit 3-7 occupies a data bus 3-9.
