Inventor: TANAKA YASUHIKO
IPC: B23K9/127
Filed: 1982-05-26
Abstract: PURPOSE:To improve easily the accuracy of the groove follow-up of a welding bead and manufacture high quality large diameter welded pipes, by controlling the right-left position of the welding head based on the information regarding the amount of displacement of the predetermined welding line of a tack welded large diameter pipe in the horizontal direction. CONSTITUTION:At two points O and P on a predetermined welding line M of a tack welded straight-seam pipe 1 laid horizontally with the groove upward, distances y1 and y2 to horizontal direction Y orthogonal to pipe axis X in points O and P are measured with industrial TV cameras 5 and 5 and the amount of displacement DELTAy=y2-y1 against the distance L between the two points O and P is found. Therefore, the inclination formed by a projected approximate line M' of the proposed welding line M upon the horizontal plane and the direction of the pipe axis X is found as DELTAy/L. Therefore, control of the welding head 4 in the horizontal direction Y performed by a controller 7 during the course of welding is performed to follow the above mentioned projected approximate line M'. The control in the vertical direction Z is performed by a copying mechanism as in the case of conventional methods.

Title: Inverter type discharge lamp lighting device
Inventor: TATENO TETSUO
IPC: H05B41/24
Filed: 1993-03-11
Abstract: PURPOSE:To provide a lighting device for a preheating intermittent oscillation operating type discharge lamp whose life is long. CONSTITUTION:Since a timer circuit 3 interrupts base current of transistors Q1 and Q2 within a set time set by a circuit consisting of time detecting resistors R4 and R5 and of an electrolytic capacitor C4, the instantaneous voltage value of a DC power supply is high, and an inverter circuit stops oscillating. But when the aforesaid instantaneous voltage value is low, the circuit reopens oscillation. This intermittent oscillation makes the output voltage of the inverter low, so that a discharge lamp 5 is prevented from being started. During the time, the lamp is preheated, output voltage becomes high, after the time set by the timer has elapsed, the discharge lamp is then lighted.

Title: Channel selection control system of frequency synthesizer receiver
Inventor: USUGOROMO KIKUO
IPC: H03J7/18
Filed: 1983-05-23
Abstract: PURPOSE:To detect a broadcast wave in the optimum reception state among plural broadcast waves being in the same program of broadcasting, by providing plural switches, plural memories, and a counter which generates an address signal. CONSTITUTION:When a received broadcast wave is deteriorated in its reception state, a switch SW1 is turned on and then a pulse signal supplied by it is supplied though an OR gate GG1, AND gate G1, and OR gate GG2 to the input IN of a counter CNT1, and the CNT1 is counted up. Therefore, a different data signal is read out of an ROM1 by a new address signal from the output OUTc of the counter CNT1 to receive a broadcast wave (of the same program broadcast) corresponding to the data signal. Therefore, a broadcast wave of a channel CH1 is received one after another every time the switch SW1 is turned on to find the broadcast wave in the optimum reception state. When a switch SW2 is on for receiving a broadcast wave of a channel CH2, the operation is performed similarly.

Output data 5a of the memory 1 is displayed on a word display equipment 14 for reference. When a word data reference signal 6a and a word display address signal 7a for reference are sent, an addition and subtraction controlling circuit 10 is started to read contents of the memory 2 to the register 6, and they are substracted by a control signal 15a and are written again in the memory 2.

Title: Metal gasket
Inventor: ASAUMI KOJI
IPC: F02F11/00
Filed: 1986-04-22
Abstract: PURPOSE:To prevent the leakage of fuel gas and increase a working life by plating the peripheral edge site of a combustion chamber hole with a surface material while forming said surface material in such a way that its thickness on the middle part sides in the longitudinal direction is larger than that on the end part sides in the longitudinal direction. CONSTITUTION:Even if unevenness is generated in the longitudinal direction of a deck because of the deformation due to a bolt clamping force or thermal strain of a cylinder head and a cylinder block between which a metal gasket 2 is installed, it can be compensated by surface materials 14 the thickness of which is larger on the middle sides than on the end sides in the longitudinal direction, formed on the peripheral edge sites 12-1-12-4 of combustion chamber holes 6-1-6-4. As a result, the leakage of combustion gas from a gap can be prevented. And, an alternate load which acts on beads 8-1-8-4 can be made lower due to the surface material 14, preventing the permanent set of the beads while increasing a working life. Also, the damage to a clamping bolt or the site of a cylinder had with which the bolt is engaged can be preventing while preventing the lowering of the clamping force of the clamping bolt, thereby, preventing the lowering of sealing effect.

Abstract: PURPOSE:To prevent a time accessed to a channel memory from being difficult to take, and a peripheral circuit from increasing, by storing a test data from a processor at a transmission data register temporarily, sending it out with the timing of an optional channel, and performing a verification. CONSTITUTION:The test data is written from a processor CC to a transmission data register SREG through a data bus DBUS, and a data bus buffer BUF. A highway transmission/reception control circuit HCONT decides the timing of a sending channel, and sends out the test data written in the transmission data register SREG to an incoming highway IHW. The test data outputted to an outgoing highway OHW is fetched in a reception data register RREG. The processor CC completes the verification of one channel by reading out the test data from the reception data register RREG through the data bus DBUS, and collating it in the processor CC.

Filed: 1990-04-05
Abstract: PURPOSE: To reduce the time necessary for obtaining sufficient calibration data by appropriately using NMRRF excitation pulse less than 90 deg. and/or cutting off a large amount of record parts of NMR response. CONSTITUTION: A phase in a plurality of continuous TR section sequences is encoded by a magnetic gradient pulse so that MRI image data for generating a nuclear set image of nuclear magnetic resonance(NMR) in an applicable image part is generated after multidimensional conversion. The calibration data of a magnetic field Bo is generated by eliminating, at least, one of the nuclear magnetic gradient pulses in recording the NMR response in each of this TR section. For example, 'one of slice times' is sacrificed for generation and record of the magnetic field calibration data of a prescribed measurement section in each of the TR section for encoding a plurality of sectional phases.  The calibration data of the phase/frequency necessary for compensating the MRI image data taken out in each TR section is obtained in relation to the changes in a magnetic field B0 in the nominal static magnetic field Bo .
