Title: Bucket type elevator
Inventor: SATAKE TOSHIHIKO
IPC: B65G17/42
Filed: 1987-04-27
Abstract: PURPOSE:To prevent drop of an article to be conveyed to a bottom part and to perform smooth lifting, by a method wherein, in a bucket elevator for lifting a granular material, the coupling part of a flat belt is covered with a cover having a slope having approximately the same inclination as that of the back wall of a bucket. CONSTITUTION:A cover 9 having a slope 12 having approximately the same inclination as that of a back wall 11 of a bucket 8 is situated to a coupling part 10 of a flat belt 7. This constitution receives rice grains discharged from the subsequent bucket 8 by means of the slope 12 and introduces the rice grains to a flow-down gutter 18. In this case, since a flange 13 is situated on the slope 12, drop to the bottom is reliably prevented, and is reliably induced to the flow-down gutter 18. This constitution prevents drop of the rice grains to a bottom part and enables smooth lifting of the rice grains.

Title: Output current detector circuit for inverter device
Inventor: IWASAKI YOSHIHIRO
IPC: H02M7/537
Filed: 1991-05-13
Abstract: PURPOSE:To detect an output-current polar signal even when a voltage drive type element is used as a power transistor by providing a means detecting voltage between one phase of a motor and a DC power and a means holding detected voltage only for a period while one phase of the power transistor is turned OFF. CONSTITUTION:An inverter circuit section 15 is supplied with a PWM signal through a drive circuit section 19 from a control circuit section 20. When an AC motor 3 is driven, phase currents IU are delayed naturally only by phase phi. An output from a photocoupler 16 is formed in a waveform including the switching of a power transistor as voltage VU at voltage EUO between the U phase of the AC motor 3 and the negative electrode side of a DC power at that time. Accordingly, voltage VU is used as an input and the ON-edge of the PWM signal transmitted from the control circuit section 20 as a trigger in a latch circuit section 21, thus holding only the state during a dead time period, then outputting voltage VOUT. Voltage VOUT is transmitted over the control circuit 20 as an output-current polar signal.

Title: Measurement of zinc dithiophosphate in lubricant
Inventor: KOIKE KEIJI
IPC: G01N33/30
Filed: 1982-06-21
Abstract: PURPOSE:To enable a highly accurate assay of Zn-DPT in a lubricant even after used by measuring zinc dithiophosphate Zn-DTP separated therefrom. CONSTITUTION:For example, a natural rubber membrance which allows the passage of a solvent A such as n-hexane dissolving a basic oil and Zn-DTP but not high polymer is used to separate the basic oil and Zn-DTP in a lubricant from high polymer components or the like in aditives. Then, the extraction liquid obtained is brought into contact with a adsorbent such as silica gel particle able to adsorb Zn-DTP but not the basic oil to adsorb Zn-DTP by the adsorbent. Additionally, a solvent B such as methylene chloride dissolving Zn- DTP is used to desorb Zn-DTP from the adsorbent. Zn-DTP in the desorption liquid thus obtained is assayed with an infrared absorptiometer or the like. This enables a highly accurate assay of Zn-DTP in the lubricant regardless of before or after the use thereof.

Title: Station by-pass processing system in data transmission system
Inventor: TAKEZOE FUMIHIKO
IPC: H04L69/40
Filed: 1979-08-23
Abstract: PURPOSE:To prevent loss of information, by performing the by-pass operation after data stored in the station disappears for by-pass of one of information processing stations connected successively. CONSTITUTION:Station control unit Sc is connected to information processing devices D1-Dn and communication units Ta and Tb. Meanwhile, lins La and Lb are connected to other stations. When unit Sc issues the by-pass command, acceptance of new data from its own station is inhibited, and acceptance of new data is inhibited in other stations also. Consequently, data held in units Ta and Tb disappears after a prescribed time. At this time, units Ta and Tb transmit the storage data zero signal, and unit Sc switches Ra and Rb by the AND output between the zero signal and the by-pass command signal to perform the by-pass operation.

Title: Method for extracting straight line
Inventor: KANEHARA HIROYUKI
IPC: G06T3/00
Filed: 1990-04-23
Abstract: PURPOSE:To reduce the occurring number of wrong extraction by discriminating whether or not the adjacent vector of a marked vector is a candidate vector for a straight line by using the angle and line width between the marked and adjacent vectors. CONSTITUTION:The angle and line width between a marked vector and its adjacent vector are used as discriminating conditions for discriminating whether or not the adjacent vector is a candidate vector for a straight line. Accordingly, it is possible to reduce such an error of extracting a large-diameter circular arc, etc., as a straight line. In case a plurality of adjacent vectors meeting the discriminating conditions exists, one of the vectors having the minimum angle and line width is selected as the candidate vector for the same straight line together with the marked vector. Therefore, the number of wrong selection of candidate vectors at the junction or diverging point of a plurality of vectors is reduced and the extracting accuracy of a straight line intersecting other segments can be raised. Therefore, the number of wrong extraction can be reduced.
