Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To improve the correspondence of mounting, to reduce material cost and to facilitate mounting works by forming the fixture side of a brace mounting section in a recessed curved surface and forming a brace mounting hole in a slot along the recessed curved surface. SOLUTION: A brace mounting hole 71 is formed on a brace mounting plate 7 on a structural member such as a column 2, a brace 6 is passed into the brace mounting hole 71, and a fixture 61 is fixed at the end section of the brace 6. In the brace mounting structure, the fixture 61 side of the brace mounting plate 7 is formed in an approximately arcuate recessed curved surface, and the brace mounting hole 71 is formed in a slot along the recessed curved surface.

IPC: B23Q11/00
Filed: 1993-04-15
Abstract: PURPOSE:To prevent a measuring probe from interference with a workpiece without attaching a collision preventing means or the like for narrowing a measurable region to a distance measuring contactless probe. CONSTITUTION:Before a workpiece is measured by a distance measuring probe on a machine, the workpiece shape is stored from CAD data or digitized data in a workpiece registering section 14 and a probe shape is stored in a probe shape registering section 13 to prepare a probe path in which the probe passes for measurement and set measuring points at a fixed interval on the surface of the workpiece. Interferences are checked sequentially in positions corresponding to the measuring points on the probe path by simulation. In the presence of the interference, the inclination angle and position changing amount of the probe is obtained and stored in a probe position and inclination angle calculating section 17 and the posture of the probe in the measurement is controlled to prevent interference.

Title: Voltage type avaf inverter
Inventor: NAKANISHI HIROSHI
IPC: H02M7/48
Filed: 1985-05-29
Abstract: PURPOSE:To eliminate a magnetic saturation of an output side transformer by detecting the variation in the DC voltage of the output side of a power inverter when a motor is started to raise an output frequency, and constantly controlling the ratio of an output voltage and the output frequency. CONSTITUTION:A voltage AVAF inverter controls by a power reactor 1 a DC voltage, and controls by a power inverter 4 an AC output frequency. The control system of the reactor 1 AVR-controls a speed command signal through a voltage command signal and a DC voltage feedback signal fed through a command converter 13 and ACR-controls an input current feedback. The inverter 4 frequency-controls a speed command by a frequency command through a command converter through a voltage/frequency converter 15. In this case, a detector 17 is provided to detect the variation in the input DC voltage of the inverter 4, thereby starting the control of the output frequency. Thus, the DC voltage starts rising by the rise of the rotating speed f a motor, and since the AC output frequency is raised, the rise in the DC voltage is suppressed.

Filed: 1990-04-27
Abstract: PURPOSE:To restrain a wavelength component which is longer than a wavelength of 490nm by mixing a blue dye with a resin-sealing member. CONSTITUTION:A cyanine blue dye as a blue dye is mixed with an epoxy resin used to mold a lens member 19. At a light-emitting diode whose mixture ratio of the blue dye is at 0.25%, the degree of a blue color is increased remarkably in an emitted light color recognized by human eyes. At a light-emitting diode whose mixture ratio of the blue dye is at 0.5%, the degree of the blue color is also increased remarkably in the emitted light color recognized by the human eyes. When the blue color is mixed in this manner, it is possible to reduce a wavelength component which is longer than 490nm.

IPC: G06F3/0487
Filed: 1990-04-27
Abstract: PURPOSE:To increase the number of degrees of freedom of key display by dividing a display face to plural blocks and outputting a registered key code at the time when touched coordinates are in the area corresponding to a key name. CONSTITUTION:Coordinates peculiar to individual display positions are given to all of the face of a display part 11, and all of the face of the display part 11 is divided to plural blocks each of which consists of a group of coordinates. When a user touches some block, a coordinate signal input part 113 outputs the coordinate signal of the touched part. If this coordinate signal indicates plural coordinates, an input coordinate taking-out means 114 selects one of them to specify the block. The key name registered for the detected block is read out, and the key code registered in a memory 116 is outputted when touched coordinates are in the coordinate area of the key corresponding to the key name. Thus, a required number of keys to which arbitrary key codes are defined are displayed in arbitrary positions with an arbitrary size. Further, quick detection is possible with a small program.

IPC: H03K17/78
Filed: 1988-05-10
Abstract: PURPOSE:To improve transient responding characteristic by pulse-driving a feedback circuit. CONSTITUTION:A switching power source ntilizes a self-oscillation using one switching element. A resistor R2 is connected to the emitter of a transistor(Tr)Q 1, and a voltage drop occurs across the resistor only when the TrQ1 is turned ON. A current for generating the voltage drop is branched to a resistor R3, and the resistance values of the resistors R2-R3 are so set as to saturate a photocoupler PC2. Thus, the output of the photocoupler PC2 is turned ON while the TRQ1 is turned ON, and it is turned OFF while the TrQ1 is turned OFF as a current switch. Accordingly, the photocoupler PC1 of the feedback circuit is driven only when the TrQ1 is turned ON by the photocoupler PC2.
