Title: Method for detecting and measuring abnormal oscillation of amplifier
Inventor: SONE KIYOSHI
IPC: H03F1/08
Filed: 1981-06-04
Abstract: PURPOSE: To stabilize the measuring level when abnormal oscillations occur, by detecting increase in the voltage at the input terminal of an IC amplifier. The increase in the voltage occurs because the signal is returned to the input terminal by positive feedback action when abnormal oscillations occur and are added to the normal input signal level.  
     CONSTITUTION: A signal source 3 is connected to the input terminal of an IC amplifier 1 through a higher signal source impedance 4. When the signal source 3 is connected, signal voltages EA and EB which occur between both ends of the higher signal source impdenace 4 and a common electric potential point, are measured. The measurement of the EA and EB is carried out at two times. One is carried out at the clipping time where the output waveform becomes abnormal and the other is at unsaturated level where the waveform becomes normal. Then the difference between two results is marked. When ΔE 1 =ΔE 2  it is judged that the oscillation is normal and when ΔE 1 <ΔE 2  it is judged that the oscillation is abnormal (where, ΔE 1 EA 1 -EB 1 ... saturated clipping level, ΔE 2 =EA 2 - EB 2 ... unsaturated level). Thus abnormal oscillations are judged through the differential level.

Title: Gas disconnector
Inventor: UEMATSU HIROBUMI
IPC: H01H33/98
Filed: 1989-04-05
Abstract: PURPOSE:To effectively extinguish an arc by providing a bottomed cylindrical shielding to cover a fixed contact and installing a gas room in the inside of the shielding. CONSTITUTION:A gas room 17 is formed in the inside of a first shielding 1 such that a cylindrical partition 16 surrounding a fixed contact 5 is fixed with one end of the cylindrical partition 16 on the bottom of the first shielding 1. Arcing occurs, therefore, between the fixed contact 5 and a movable contact 15 at the initial time of disconnection, and when an insulated gas heated by arc and pressure-elevated pushes a piston 14, it moves to open a pressure hole 22 with the result that the pressure-elevated insulated gas moves to the gas room 17 from the pressure hole 22 and then, the pressure of the gas room 17 increases. When the movable contact 15 comes out of the insertion hole 4a of an insulation nozzle at the latter time of disconnection, the piston 14 is pushed back by the tensile force of a spring 20 due to a pressure difference between the outside and the inside of the shielding with the result that the pressure hole 22 is closed and concurrently, the insulated gas of the gas room 17 is discharged to the outside of the shielding 4 from the insertion hole 4a, and blown against the arc. Thereby, an arc can be effectively extinguished.

Abstract: PURPOSE:To eliminate troubles such as flowing-out of contents or defective sealing arising from defective holding of pouches by a method wherein positions of the held pouches are detected, and controls are executed to stop operations on the following processes after the next for the pouches that are not held in correct position. CONSTITUTION:Each of pouches taken out one after another, being sucked by a sucking disk or the like, from a pouch stand 2 is held correctly with grippers at both ends near its end on the openingside, and is sent to stages of processes after the next, including a mouth opening stage 4, a filling stage 5, a sealing stage 6 and a cooling stage 7, and sent out to a carrying-out stage 8. In the case where defective holding is detected in a position-detecting stage 3 for any of the pouches, signals are sent from the position-detecting stage 3 in consecutive order to the following stages of processes so that the pouch for which defective holding is detected can be sent, passing by all of the following stages of processes and sent out to the carrying-out stage 8 without undergroing any of the processings, and driving for every stage of processes can be controlled automatically with a sequencer or the like. Thereby, troubles such as flowing-out of contents or defective sealing can be prevented, and the pouches found to be defectively held become reusable.

Title: Retrying system for address converter
Inventor: YAMANO KOZO
IPC: G06F12/10
Filed: 1989-04-05
Abstract: PURPOSE:To improve an operation rate and to shorten a fault processing time at the time of generating an intermittent fault by retrying address conversion processing without immediately informing the generation of a temporary intermittent fault to a system. CONSTITUTION:The generation of a parity error is informed to an address conversion fault processing part 2 in an address converter at first without directly informing the error to a fault processing part in the system. When a retrial is not executed yet based upon the state of a retrial executed flag 2-1 in the processing part 2, an address conversion restart gate 2-2 is turned on and a signal outputted from the gate 2-2 is transmitted to an address conversion control starting circuit 3 and an address conversion control clearing circuit 4. An address conversion control circuit 1-2 is cleared by a signal outputted from the circuit 4 and restarted from the circuit 3. In the case of a temporary intermittent fault, address conversion can be ended without almost generating a parity error in the 2nd address conversion based upon the retrial. Consequently, the fault processing time can be shortened without dropping the operation rate of the system.

Abstract: PURPOSE:To enable irradiation with beams of light over a wide range on a test object by irradiating the test object directly with beams of light diffused by a diffusion plate over a wide range and by guiding the reflected light in a direction different from that of incident light. CONSTITUTION:An emitted beam of light from a light source 2 is guided to a vicinity of a test object 10 by an optical fiber 14: after a diffusion plate 16 enlarges the irradiation range, this beam passes through a half mirror 6 to irradiate the object 10 from sideward. The mirror 6 reflects the reflected light of the object 10 in parallel with the axial line of the object 10, and a reflector 18 counterposed against the mirror 6 reflects that reflected light sideward by 90 deg.. A prism 20 totally reflects and guide it to an objective 8 of 90 deg. upward microscope 4 for further magnification; then, a CCD camera 12 forms an image. That is, the reflected light of a beam having irradiated the object 10 directly over a wide range is guided in a direction different from that of incident light for image formation. Therefore, a wide range of reflected light can be introduced into the lens 8, and a magnified image can be obtained regardless of direction of incident light and position of light source.

Title: Thermal deformation correcting method for electronic part loader
Inventor: TOMITA MASAMICHI
IPC: G05D3/12
Filed: 1991-04-19
Abstract: PURPOSE:To keep the loading accuracy of electronic parts onto a substrate satisfactory for a long time by repeatedly executing position correction in a fixed cycle so as to correct position deviation while measuring the position of an adsorbing device to an image pickup device for recognizing parts. CONSTITUTION:An adsorbing nozzle 3 is loaded to an adsorbing device 12, and nothing is adsorbed to the nozzle 3. The adsorbing device 12 is positioned in the field of view above an image pickup device by operating a robot 1. The adsorbing device 12 is autonously positioned at every angle equally dividing a circumference, the image of the adsorbing nozzle 3 is picked up by an image pickup device 8 plural times such as fourtimes at every 90 deg., for example, and the central position coordinate of the silhouette of each image is measured. The average value of all the measured values is calculated, and this value is defined as the rotational center position coordinate of the adsorbing nozzle 3. At this time, when the thermal deformation of a ball screw 10 is in a transient state and it is estimated that the necessity of correction is high, the correction is repeatedly executed in the fixed cycle only during that period. On a stage where the ball screw reaches normal temperature and the extension is converged at a fixed value, the machine is continuously operated without being corrected.
