Title: Suction type screw feeder
Inventor: SHINOHARA RYOJI
IPC: B65G33/14
Filed: 1986-10-25
Abstract: PURPOSE:To quantitatively send out the powdered granules without generating a pulsation flow by installing an air taking-in port or a secondary air taking-in port onto the downstream side of the contact part of a screw. CONSTITUTION:The powdered granules introduced from a powdered granule receiving port 8 are pushed forward by the revolution of a screw 2, and almost all the parts are transported by the air in an inhaled air transport pipe 7, and a part tends to adhere onto the screw surface A at the top edge of the screw 2. Since, on the screw surface A, the air introduced from an air taking-in port 4 always collides and cleaning for the powdered granules is repeated, the part C where the powdered granules are piled over an angle of repose is not formed. When the powdered granules tend to accumulate at a corner of the screw surface, the secondary air supplied from a secondary air taking-in port 6 is effective, and together with the air supplied from the both air taking-in ports 4 and 6, the powdered granules piled on the screw surface A are stationarily fed into the inhaled air transport pipe 7.

Title: Oil feeder
Inventor: MOTOHASHI TOSHIAKI
IPC: B67D7/04
Filed: 1991-09-04
Abstract: PURPOSE:To stabilize the operation of a flow rate control valve in a blended oil feeder to maintain the accuracy of mixing ratio and oil feed rate and prevent damages to the flow amount control valve. CONSTITUTION:There is provided a valve driving means 25 which regulates the amount of the fluid fed from flow rate control valves V1 and V2 provided in two liquid feed means according to the mixing ratio and opens and closes the flow rate control valves V1 and V2 alternately to regulate the flow amount when the feed rate becomes smaller than the reference value. Upon feeding oil in a large flow, since the operation of the flow rate control valves V1 and V2 is stable, the valve opening degree is controlled by one pulse at a time to adjust the feed rates of two kinds of fuel oil in order to attain the target mixing ratio. When the oil feed enters the final feed stage reducing the feed amount, the flow amount control valves V1 and V2 are set at such opening degrees as to provide the minimum flow rate to assure their stable operations and the valve opening time is controlled under these opening degrees to adjust the oil feed rate. This permits the operation of the flow rate control valves V1 and V2 without causing hunting even during the final oil feed in a small flow.

Filed: 1994-10-19
Abstract: PURPOSE: To directly measure contact load in a running state equal to that of an actual machine by providing a magnetic core transforming the contact load into a magnetostriction and winding a signal detecting coil for taking out a detection signal around the magnetic core. CONSTITUTION: One pair of magnetic half bodies 11, 12 consisting of magnetic material such as ferrite are butted to each other through a gap material made of magnetic material 16 having a gap (g) to form a magnetic core 13. Then, a winding is applied to a winding groove 14 provided in the magnetic core 13 to form a coil 15. In this magnetic head 11, a recording and a reproducing with respect to a video tape being a magnetic recording medium are performed by a leakage magnetic field generated in the vicinity of the magnetic gap (g). However, in this load measuring instrument, it is different from the magnetic head that the magnetic core 3 is constituted while magnetic core half bodies 1, 2 are butted without having a gap equivalent to the magnetic gap (g).  Consequently, a closed flow-path is formed without generating a leakager magnetic field and this load measuring instrument is not affected by a magnetic influence from the magnetic recording medium, etc.

Abstract: PURPOSE:To reduce the size of hardware and to shorten an arithmetic processing time of software by setting up four picture elements of an original image surrounding the picture elements of a noticed conversion image to A-D, calculating logical values in respective noticed picture elements in accordance with four tables previously determined on the basis of specific conditions and using ORs of the calculated logical values as binary information. CONSTITUTION:The coordinate value rj of a converted picture element R in the direction (j) is calculated and the coordinate value rj is compared with a previously set value 2-1/alphaj to calculate the coordinate value ri of the converted picture element R in the direction (i). Then binary information Ia-Id of the four adjacent picture elements are entered and the coordinate value ri is compared with the previously set value 2-1/alphai. The OR of the binary information values of the original picture element previously prepared on a route corresponding to the compared result is determined as binary information Ir. Said steps are repeated in the direction (i) and then in the direction (j) to obtain converted picture element information. Consequently, four combinations of conditions for the value Ir of the converted picture element R are formed, so that the conditions can be discriminated by repeating comparison/ decision twice.

Title: Image pickup device
Inventor: HARUKI TOSHINOBU
IPC: H04N5/243
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To minimize the deterioration in the resolution by not only extending distortion singly according to a theoretical equation but also conducting image reduction conversion at the same time in the case of executing distortion correction so as to bring lots of image pickup information to a valid area. SOLUTION: In the case of reading an image based on a correction coefficient corresponding to distortion by an optical system 1, read position from an image memory 5 is changed and distortion correction is executed. Then an address generating circuit 13 reduces an image pickup pattern into a prescribed size by an electronic zoom function. The read address is returned to a read control circuit 12. Furthermore, image data stored in the image memory 5 are stored for each picture element of an image pickup element 2 with respect to a video signal, or data may be stored for each picture element group consisting of plural picture elements.  Thus, when the same pattern as the reduced image is displayed by conventional correction only, by validating image data of a region having been aborted in a conventional device, the resolution is improved by image data in validated parts in the aborted area.

Title: Manufacture of semiconductor device
Inventor: KANAZAWA HISATOMO
IPC: H01L21/322
Filed: 1985-11-13
Abstract: PURPOSE:To produce a semiconductor device with its performance characteristics stable by a method wherein a prescribed low-temperature heat treatment follows a prescribed high-temperature heat treatment for the diffusion of platinum into a silicon substrate provided with a P-N junction. CONSTITUTION:Pt is diffused into silicon crystals at a prescribed high temperature, for example at 800-1,000 deg.C, and then another heating is accomplished at a temperature affecting only the reverse recovery time but not the forward or backward voltage withstanding capability, that is, at 600-700 deg.C. Pt performs inter-lattice infiltration or lattice replacement when it is diffused into a silicon crystal. Because of a small degree of said solution in silicon crystals, Pt diffused into silicon crystals beyond the limit of its solid solution capability, precipitates at such crystal defects as dislocation or vacancy, especially in the cooling process. A second heating at a low temperature returns the Pt precipitating at lattice defects into between lattices or into a lattice. This increases the quantity of Pt solved in silicon crystals. This reduces in half the dispersion (a) of switching characteristics without degrading any other characteristics, which contributes to the improvement in performance and in the rate of yield.
