Title: Motor driven injection molding device
Inventor: KUMAMURA MASAAKI
IPC: B29C45/76
Filed: 1990-03-28
Abstract: PURPOSE:To decide back pressure to be applied to a screw by only output of a back pressure giving device, by a method wherein measurement is performed under a state where rotary driving system of the screw is separated completely from straight moving driving force by changeover device of a clutch. CONSTITUTION:A hollow ball screw 6 is raised and stopped at a measurement waiting position and measurement and kneading are performed under a state where an injection clutch is detached, that is, a state where a screw 2 is detached completely from a motor 19. In other words, at the time of the measurement and kneading, only rotary driving force is applied to the screw 2 and detached completely from a straight moving driving system (the motor 19 or the ball screw 6 or a ball nut 9) in a vertical direction. Therefore, only thrust of a vertical direction by measurement of a molding material is generated in the vertical direction of the screw 2 and along with progress of the measurement the screw 2 is raised away. In this instance, the back pressure to be applied to the screw 2 to control dispersion in the measurement is decided by only output of a back pressure cylinder 22. Capacity of a measured molding material is decided by a movement distance route length of the screw 2 to be detected by a measurement completion detecting sensor 25.

Title: Viscous cup ring durability testing device
Inventor: NISHIKUMA YASUSHI
IPC: G01M13/02
Filed: 1991-04-15
Abstract: PURPOSE:To perform an accurate durability test in a short time using a durability testing device for a viscous cup ring by detecting pressure or gas concentration within the viscous cup ring. CONSTITUTION:A viscous cup ring 10 is disposed inside an oil reservoir 50 and as the inner shaft of the ring 10 is rotated by a motor 54 torque applied to a fixed outer case is measured by a torque sensor 62. A pressure sensor 74 which measures the internal pressure of the viscous cup ring 10 is provided to measure the relation between a predetermined testing time and changes in the pressure. A pressure buildup after a predetermined measuring time is related to the result of a durability test based on any increase in torque at predetermined rates; i.e., the greater the pressure buildup the worse the durability; (i.e., the actual travel distance is short). As a result, the durability can be detected from the amount of the pressure buildup obtained in a relatively short time. Detection of the amount of gas generated within the cup ring 10 may be performed in place of the measurement of the pressure.

Abstract: PURPOSE:To reduce test time in the case of testing by loading many pieces on a memory test equipment and to enable the detection of the inversion defect of all bits. CONSTITUTION:A comparison data register 10 is provided by which, at the time of test mode, a comparison data DC corresponding to the expected value of the data of a set of plural bits read out from a memory cell array part 1 is taken in at a prescribed timing.

Title: Quantity measuring instrument for carried article such as egg
Inventor: IDA ATSUO
IPC: G06M7/00
Filed: 1989-03-31
Abstract: PURPOSE:To correctly measure a quantity in a simple configuration by intermittently image-picking up only the section between the conveyer supporting members by means of an image sensor camera. CONSTITUTION:When eggs 6 are carried by being locked by means of bars 3 of a flat conveyer 1, a photoelectric switch 15 detects any one of the bars 3, and simultaneously a CCD camera 4 image-picks up a carrying surface 5. At such image pickup timing, the camera 4 image-picks up the position between the bars 3, and the bar 3 is not image-picked up. Consequently when the egg exists immediately under the camera 4, only the egg 6 is surely image-picked up, and the suitable image is outputted. Thus a clearly discriminating slice signal can be obtained, the bar 3 is not erroneously counted as the egg 6, and the correct quantity can be measured in the simple configuration.

Title: Volumenometer
Inventor: ISHII YASUSHI
IPC: G01F17/00
Filed: 1994-03-31
Abstract: PURPOSE:To enable the volume of even a soft container such as a thin-walled plastic bottle to be measured by controlling a second sound source so that pressure variation inside a compensating container equals that inside the container to be measured. CONSTITUTION:When a diaphragm 7 is displaced by the driving of a loudspeaker 6 and the volume V1 of a reference container 1 expands by a micro volume DELTAVS, the sum of the volume V0 of a measuring container 2 and the sum V3 of a container 3 to be measured is compressed by the DELTAVS. When pressure variations in the container 1, 2 are -DELTAAP1, DELTAP2, respectively, the volume V3 is determined by the measurement of -DELTAP1/DELTAP2, and when the container 3 is soft, its wall vibrates with a variation of DELTAP2, causing errors in measurements. Therefore the container 3 is covered with a compensating container 20 equipped with a loudspeaker 24 that serves as a second sound source. The container 20 has its volume varied by the displacement of a diaphragm 25 due to the driving of the loudspeaker 24, and a microphone 21 detects a pressure variation DELTAPC for output to a differential amplifier 23. The amplifier 23 also inputs the output of the amplifier 14 and controls the loudspeaker 24 so that the difference between the two inputs becomes zero. Therefore, the pressures inside and outside the wall of the container 3 are in equilibrium and the wall does not vibrate, enabling the volume to be measured accurately.
