Patent JP-H02195465-A (JP)
Title: Dma circuit
Inventor: TAKAGI MASAHIKO
IPC: G06F13/28
Filed: 1989-01-25
Abstract: PURPOSE:To use a compact dynamic RAM as a data buffer by using a data request signal outputted from a peripheral control part as a count-up signal for a column address counter to generate a column address. CONSTITUTION:At the time of receiving a CAS signal, a data memory 2 is turned to a state capable of outputting data from a memory. When a data request signal (b) is outputted from the peripheral control part 1 under that status, the signal (b) is inputted to the column address counter 4 and the contents of the counter 4 are counted up, so that a column address (d) is successively counted up in each generation of the signal (b). Thus, a compact dynamic RAM can be used by attaining rapid address generation so that a column address in a rapid page mode is generated from the counter whose contents are counted up in response to a data request signal generated from the peripheral control part 1.

Title: Brushless motor driver
Inventor: OKU HIROYUKI
IPC: H02P6/06
Filed: 1990-01-25
Abstract: PURPOSE:To start a motor smoothly by outputting a conduction switching pulse preferentially if it is produced while outputting a conduction state transition pulse if the conduction switching pulse is not inputted within a predetermined time. CONSTITUTION:When a rotor is rotated through conduction switching with a starting pulse Po and a voltage is induced, conduction switching pulses PU, PV, PW are outputted. If the conduction switching pulses PU, PV, PW are produced earlier than a time predetermined by a timer circuit 4, the timer circuit 4 is reset before the predetermined time elapses and thereby no starting pulse Po is produced, and conduction switching of driving coils 8a-8c is carried out by means of the conduction switching pulses PU, PV, PW. More specifically, if the conduction phases of the driving coils 8a-8c are not switched even upon elapse of the predetermined time, the conduction state is switched and the conduction phase is switched preferentially with the timing of the conduction switching pulses PU, PV, PW.

Title: Joining device for band-shaped metallic sheet
Inventor: SAWADA HIROKAZU
IPC: B23K9/025
Filed: 1990-01-25
Abstract: PURPOSE:To surely join the butt parts of band-shaped metallic sheets to each other by providing a bypass circuit which is disposed in parallel with a welding means for joining the ends of the band-shaped metallic sheets to each other and controls the welding current flowing in the welding means and a means for making on-off control of the bypass circuit. CONSTITUTION:A part of the current from a three-phase AC power source flows through the bypass circuit 44 and the welding current falls when a switch 44B is turned on via a control circuit 36 by the command from a current program circuit 38 when a torch 30 arrives at a point A. The switch 44B is turned off by the control of a control circuit 36 when the torch 30 arrives at a point B. The current no longer flows in the bypass circuit 44 and the welding current flowing in the torch 30 increases. The switch 44B is turned on and the welding current decreases when the torch 30 arrives at a point C. The low welding current is passed at both side edges of the band-shaped metallic sheets 10, 22 and the high welding current in the central part in such a manner; therefore, the approximately uniform melting is executed at both side edges and in the central part and the sure joining by welding between the butt parts is executed.

Title: Filler rod for tig welding
Inventor: YANAGIDATE KIYUUKICHI
IPC: B23K9/16
Filed: 1979-02-16
Abstract: PURPOSE:To enable TIG one side welding of stainless steel to be readily accomplished without using back shielding gas by coating the flux containing the limited  amount of TiO2 at the specific ratio on the stainless steel core wire. CONSTITUTION:The flux containing 30-85% of TiO2 is mixed with a binder such as water glass so as to become 5-25% based on the weight of the filler rod and the mixture is covered and coated on a stainless steel core wire, after which it is dried and fired. When this filler rod is used, the filler rod is melted by arc heat at the time of TIG welding and the weld metal forms back beads. At the same time, the slag produced at that time encloses the back beads thereby preventing the oxidation by the atmospheric air. Hence, even if back shielding gas is not used, it becomes possible to obtain the sound back beads.

Title: Oscillator
Inventor: KUNO TAKASHI
IPC: H03K3/03
Filed: 1983-02-03
Abstract: PURPOSE:To decrease the transient time by constituting an oscillator with a one- shot multivibrator. CONSTITUTION:The one-shot multivibrators OSM6 and 7 are vertically connected, and these OSMs are actuated every second one with positive and negative power supplies. When a command signal is applied to a trigger input terminal 10, the OSM6 actuated by the negative power supply produces pulses of negative voltage. The rear edge of the pulse is applied to the trigger input terminal of the OSM7 of the next stage. Thus the OSM7 actuated by the positive power supply produces pulses of positive voltage. If the outputs of these two OSMs are added together through an adder circuit 8, a bipolar output is obtained. Then the oscillation is continued if the output of the OSM7 is fed back to the input of the OSM6 of the first stage.

Title: Detector for curved graph
Inventor: MORI NOBUHIKO
IPC: G01B21/20
Filed: 1979-02-14
Abstract: PURPOSE: To detect the presence of curve in the character graph, by picking up three points toward the row direction when 3 rows are present from the partial graph in the memory and picking up three points toward the column direction in case of three columns and using the combination of features.  
     CONSTITUTION: To detect the upward curve, the signal can be the continuity of 1XX,001,1XX. X indicates either of white or black. FF8 is set with -S 1 XX from the shift register 6. Accordingly, since FF9 is set with the output 001 of the decoder 7, the AND gate 10 is outputted with S 1 XX of the register 6. Thus, the output U of the gate 10 is the upward curved detection signal. FF9 is reset with the reset pulse R 1  of the control circuit 14 and reset with 000 of the decoder 7. That is, reset is made even if the pattern is interrupted. The pulse R 1  is a pulse produced when the graph of three row width is set to the shift registers 4W6. FF9 is reset with the timing of the clock 1 even with the detection signal of the gate 10. Thus, even if the feature is preset in the form partly in common use, it can be detected.
