Title: Overhead traveling vehicle
Inventor: OMORI AKIHIKO
IPC: B66C13/23
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To control lowering of a hand without accurate teaching or any guide poles by providing a workpiece detection sensor for detecting the position of a workpiece and a hand control means for stopping lowering of the hand based on a workpiece detecting signal in the hand. SOLUTION: When a hand 12 is brought close to a target position and loading is carried out, a workpiece is detected by a workpiece detection sensor in the vicinity of a centering member 120 positioned close to the holding plate 010 of a workpiece upper end. Chucking is not allowed in this position, lowering of the hand 12 is continued, a lowering distance during this time is read by an encoder and the movement of the hand 12 is stopped when it is lowered by a specified length after the detection of the workpiece. Then, a chuck 126 is rotated, the workpiece is held and the hand 12 is experimentally raised by a specified length. Then, when the workpiece detection sensor is changed from a closed state (workpiece detected) to an open state (workpiece not detected), the hand 12 is raised understanding that loading is stably carried out.

Abstract: PURPOSE:To improve the efficiency of an inverter, by driving in a constant- current manner the emitters of the switching transistors of a Royer oscillation circuit with the collector output of the output transistor of an IC for controlling a DC-DC converter. CONSTITUTION:Constant-current control of the discharge current of a cold- cathode discharge tube 31, which is the load of an inverter, is performed by making the average value of the switching currents of switching transistors 11, 12 of a Royer oscillation circuit variable depending on the value of the discharge current. That is, the emitters of the switching transistors 11, 12 of the Royer oscillation circuit are driven via a choke coil 23 by the collector of an output transistor 113 of an IC 20 for controlling a DC-DC converter. Therefore, the average current of the Royer oscillation circuit is made low, and the discharge current is controlled in a constant-current manner. Thereby, the efficiency of the inverter is improved.

Filed: 1979-10-31
Abstract: PURPOSE: To enable to discharge the fluid continuously at a constant rate, by shaping a cam for driving pistons to have a developed surface in the from of a Sin 2 θ curve.  
     CONSTITUTION: Four pistons 4 are disposed equidistantly along the same circumference, and sinusoidal curves F 1 WF 4  having a maximum fluid discharging velocity respectively at angles of 90, 180, 270 and 360 degrees are formed as shown at (a)W(d) in the drawing. By superposing these sinusoidal curves as show at (e) in the drawing, fluid is discharged at a resultant flow rate (f) since an equation Sin 2 θ+Cos 2 θ=1 is satisfied. That is, fluid is drawn into cylinders 2 by the movement of pistons 3 and discharged at a rate conforming to the differential curve of Sin 2 θ on its positive side at a velocity of pistons 3 determined by a cam 6. Therefore, the resultant discharge rate of fluid can be controlled to be always constant by combining these for sinusoidal curves.

Abstract: PURPOSE:To automate inspection and ensure production efficiency and quality stability by concurrently undertaking the inspection of a display section and the inspection of the click feeling of an operation button. CONSTITUTION:A character display board 2 on a product 1 is photographed with a TV camera 4. This photographed image is processed in a display inspection section 5, using an A/D conversion circuit, a sampling circuit, an image memory and a computer, thereby inspecting whether a defect is existing or not. At the same time, the finger 6 of a button pressing section 10 is actuated with a drive section 8, and an operation button 3 is thereby pressed. The pressing force of the button 3 is, then, transmitted to a pressure sensor 7. This system can be realized, using a robot and an orthogonal 3-axis drive system. A click feeling inspection section 9 processes pressure information from the pressure sensor 7 and positional information from the drive section 8, and makes judgement as to whether click feeling is good or not. Namely, the displacement-load and time-load curves of the button 3 are approximated by line segments among plurality of characteristic points typical of the curves, and the acceptance or non-acceptance of the click feeling is judged on the basis of the absolute and relative values of each characteristic point, and the gradient of each line segment.

Abstract: PURPOSE:To reduce crossover distortion by setting a binary signal amplification system as one system by using an absolute value circuit, a polarity reproduction circuit, and a control circuit. CONSTITUTION:A signal proportional to the absolute value of input from an analog signal source 1 via an operational amplifier 4 is generated at the output terminal 8 of an operational amplifier 7. The signal is converted to a binary signal with a pulse modulator 9, and an activation voltage is outputted to a terminal 15 via a transistor(TR) 10 and filters 12 and 13 when no signal is inputted.

The signal inputted to an operational amplifier 24 is inputted to TRs 25 and 26, and the activation voltage applies the TRs in an activation area, therefore, the signal proportional to the negative half wave of an input signal can be obtained at an output terminal 27. The signal inputted to TRs 32 and 33 via an operational amplifier 31 is outputted as the one proportional to the positive half wave of the input signal. Such difference becomes output, then, the distortion can be eliminated.

Title: Optical data storing and reproducing device
Inventor: SUETSUGU TOSHIO
IPC: G11B7/125
Filed: 1989-06-05
Abstract: PURPOSE:To prevent the excessive light emission of semiconductor laser at the time of switching by lengthening the light emitting time of the semiconductor laser and reducing the output of a comparator before switching a record-hold mode to a reproducing mode. CONSTITUTION:A DC signal is generated until the switching is performed instead of a dummy signal of an information signal b from an information signal generation circuit 14 before switching the record-hold mode to the reproducing mode. Then, the semiconductor laser 3 emits light for a long term, which is received by a photodetector 11, and after it is converted into an electric current and a voltage, the (+) input of the comparator 5 becomes low and the output of the comparator 5 can be reduced until the switching is performed. Thus, the excessive light emission of the semiconductor laser is prevented at the time of switching the record-hold mode to the reproducing mode.
