Title: Pulse arc welding method
Inventor: TABATA YOICHIRO
IPC: B23K9/09
Filed: 1988-09-20
Abstract: PURPOSE:To carry out satisfactory spray transfer by detecting the arc voltage to change according to an interval between a wire electrode and base metal and allowing a pulse of a pulse arc current to rise when it becomes less than the prescribed minimum voltage and supplying a set pulse arc current. CONSTITUTION:The wire electrode 10 is sent to a welding torch 9 and short- circuited to the base metal 10 and this short-circuit voltage is detected by a voltage detector 12 and compared with the minimum voltage VBO and an ON command of the arc current increase is given to a switch commanding device 22. As a result, the arc electrode 10 becomes red-hot and is burnt off and when a welding arc is started, the prescribed pulse arc current is supplied and the electrode 10 tip is molten and the spray transfer is carried out. After the pulse arc current is supplied, an OFF command to decrease the arc current is given to the switch commanding device 22 and the electrode 10 tip again approaches the base metal 11 and the arc voltage Va is reduced. When the arc voltage Va becomes less than the minimum voltage VBO, a comparator 191 is operated and the ON command of the arc current increase is given to the switch commanding device 22.

Title: Tool tip measurement
Inventor: SHIRATORI HIDEFUMI
IPC: B23Q17/22
Filed: 1986-10-03
Abstract: PURPOSE:To permit the improvement of correction accuracy and the reduction of a measuring time, by causing 1st and 2nd sensors mounted on the outer circumference of a measuring unit to make contact with the tip of a tool for outer diameter and the 2nd and a 3rd sensors mounted thereon to make contact with the tip of a tool for inner diameter for thereby correcting the tip position. CONSTITUTION:When the tip of a target tool 51 makes contact with a sensor 11Z on the positive side of a Z axis, a sensor unit 1 produces a signal and at the moment the amount of movement Z1 counted by an NC control unit is registered in a register 44a. Since a signal circuit is independently wired for respective sensors, they are capable of indicating address positions and since the initially designated sensor is self-held at an address unit 3, no signal is supplied even if a contact is made with sensors other than this one, which serves as a confirmation for preventing an operation mistake. Since the tip 51 of the cutting tool for outer diameter is directed toward the outside or the negative side of the Z axis, the 2nd sensor 11Z and a 1st sensor 11X are selected as a contact mate and the 2nd sensor 11Z and a 3rd sensor 12X are selected in the case of the tool for cutting inner diameter, whereby the improvement of correction accuracy and the reduction of a measuring time are permitted.

Title: Lead section structure for enzyme sensor
Inventor: MATSUOKA MIKIYA
IPC: G01N27/409
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent the output of an enzyme sensor from dropping by reducing the current leakage between an air-side lead section and an exhaust-side lead section. SOLUTION: In a lead section structure for enzyme sensor, the reactions of an exhaust-side lead section 11 to an exhaust gas and an air-side lead section 9a to the air are prevented, because the section 11 is covered with an exhaust- side sealing sheet 5 so as to prevent the section 11 from coming into contact with the exhaust gas and the section 9a is covered with an atmosphere-side sealing seat 6 so as to prevent the section 9a from coming into contact with the air.  Therefore, when the sections 11 and 9a are heated to about 800 deg.C with a heater so as to improve the performance of the enzyme sensor by improving the electromotive force characteristic between an air-side electrode 8 and an exhaust-side electrode 10, the activation of oxygen movement between the sections 9a and 11 is suppressed cojointly with the suppression of the reactions of the sections 9a and 11 to the air and exhaust gas.

IPC: G05D3/00
Filed: 1992-09-03
Abstract: PURPOSE:To detect an open circuit with simple circuit constitution regardless of whether operation is performed or not by composing the circuit of an adder, a difference unit, and a level detector. CONSTITUTION:A phase (a) of an encoder signal is denoted as Esintheta and a specific DC level is denoted as VREF. The output signal S3 of the difference unit 21 as the difference between the output signal S1 of a 1st adder 11 and the output signal S2 of a 2nd adder 13 is 2Esintheta, which is outputted to the encoder servo mechanism. The output signal S4 of a 3rd adder 22 of an open circuit detecting circuit D is 2VREF1, which is outputted to the level detector 23 which judges an open circuit between lines L1 and L2 between the transmission side and reception side for an encoder signal. When there is no open circuit, the output is 2VREF, but if an open circuit is formed on L1 or L2, S4=S1 or S4=S2 holds and when the both have open circuits, S4=0. For the purpose, the level of S4 is detected by the level detector 23 to detect the open circuit.

Title: Back raising apparatus
Inventor: ISHIDA MICHIYASU
IPC: A61G7/00
Filed: 1987-09-22
Abstract: PURPOSE:To eliminate the slip-down of a patient toward his leg side, by detecting the shift of the back from the back support part and moving the back support part in a direction not generating said shift. CONSTITUTION:When the back of a patient is raised, that is, the upper part of the body 1 begins to raise, since the center of rotation of the patient is different from that of a chair, slip is generated between the back of the patient and the upper part-of-body support part 4. This slip is detected by a roller 15 and a motor 14 is driven in a direction eliminating said slip corresponding to the detection result to move the upper part-of-body support part 4 up and down. The upper part-of-body support part 4 moves up and down by the rotation of the motor 14 through a screw 13 and a nut 12.

Title: X-ray protection circuit
Inventor: YAMAKI MOTOI
IPC: H04N3/18
Filed: 1991-09-17
Abstract: PURPOSE:To realize the detection of excess current and the detection of excess voltage with a few circuit scale and to suppress X-ray radiation amount to specified amount and less. CONSTITUTION:When excess current exceeds VBE of a first detection transistor Qc, this is turned on, a third control transistor Qd is turned on by the voltage at that time and the supply of a horizontal drive signal is stopped. As the result, the oscillation of a flyback transformer 12 is stopped and X-ray is stopped to be radiated to specified amount and more by excess current. From excess current, a CRT and the flyback transformer 12 are protected. As a second detection transistor Qe is turned on at the time of excess voltage, the first detection transistor Qc is also turned on and a first control transistor Qa is compulsorily turned off. Thus, X-ray is not radiated to specified amount and more by excess voltage since the oscillation of the flyback transformer 12 is stopped. A second control transistor Qb can be protected also from excess voltage.

Title: Ic composite parts
Inventor: MORII HIROSHI
IPC: H01G4/40
Filed: 1989-09-11
Abstract: PURPOSE:To prevent exfoliation in an interface between both ceramic parts, and restrain mutual diffusion, by interposing ceramic material as an intermediate layer between a dielectric ceramic part and a magnetic ceramic part, which ceramic material is composed of only ZrO2, TiO2 or their mixed system and a specified amount of CuO. CONSTITUTION:A first intermediate layer 5 and a second intermediate layer 6 are interposed between a magnetic ceramic part 4 and a ceramic part 2 and between the magnetic ceramic part 4 and a ceramic part 3, respectively. These parts constitute a capacitor. Ceramic material of the intermediate layer contains ZrO2 and TiO2 of arbitrary mole ratio, (ZrO2:TiO2=0-100:100-0), in which CuO of 0.5-30mole% is contained. When the content of CuO is less than 0.5mole%, sintering properties are inferior. When the content is less than 30mole%, the controlling width of a baking shrinkage factor is decreased. When the content is in the range of 30-50mole%, a mean baking shrinkage factor is obtained, stress caused by the difference of each shrinkage factor is relieved, and mutual diffusion is restrained.

Title: Image forming device
Inventor: SHIOJI HIROYUKI
IPC: G03G21/20
Filed: 1994-09-30
Abstract: PURPOSE: To rotate a cooling fan into a blowing direction in both forward and backward movements of an optical system. CONSTITUTION: Because a driving force which makes the optical system 3 to run along an original platen is transmitted to the cooling fan 10 via two clutches 13 and 14 of different directions in connection, the cooling fan 10 can be rotated and driven in the same blowing direction in both the forward and backward movements of the optical system 3. Therefore, when the optical system 3 is driven to run, the cooling fan 10 always rotates, and the original- platen-cooling effect improves. The use of two one-way clutches of different directions in connection, as the clutches 13 and 14, makes it possible to transmit the cooling fan 10 the driving force by connecting one of the one-way clutches that rotates the cooling fan 10 into the blowing direction due to the running direction of the optical system 3.  Alternatively, two electromagnetic clutches that are alternately connected in the forward movement and backward movement of the optical system 3 can also be used.
