Patent JP-H02249962-A (JP)
Title: Fet sensor
Inventor: KATSUBE TERUAKI
IPC: G01N27/00
Filed: 1989-03-23
Abstract: PURPOSE:To facilitate the manufacture, and also, to enhance the responsiveness by generating a depletion layer on the surface of a semiconductor layer, and also, allowing a source - drain current to flow to the semiconductor layer being right under a depletion layer. CONSTITUTION:When a voltage is applied to a gate electrode 7, the depletion layer is generated in the upper layer part of a semiconductor layer 2 between a source electrode 3 and a drain electrode 4, and a source - drain current flows smoothly through the inside of the semiconductor layer 2 being apparently right under its layer. Accordingly, in order to insulate the surface of the semiconductor layer 2, a protective film is formed on a gate part, such a process as it is scraped again is eliminated and also, it is unnecessary to form a p-n junction in source and drain areas, therefore, the manufacturing process is simplified. Also, due to the structure in which the source and the drain electrodes 3, 4 are joined with the semiconductor layer 2, a noise becomes low, and also, the electron mobility becomes large, and an FET whose high frequency characteristic is excellent is obtained.

Title: Device for removal of coarse particle from atomized metal powder slurry
Inventor: NAKAMURA KOSHIKIBU
IPC: B01D29/62
Filed: 1991-04-05
Abstract: PURPOSE:To automatically remove the coarse particles causing clogging by providing a coarse particle removing tank vertically a slurry pipe to and larger in diameter than the slurry pipe at an intermediate portion of this pipe for transferring slurry-like metal powder to a dehydrating system. CONSTITUTION:Coarse particles, together with some water, can be carried out from a dehydrating system even during operation by means of two tier dampers 15a and 15b provided on the bottom part of a coarse particle removing device and a screw feeder 11 mounted thereunder. Since the diameter of a coarse particle removing tank 20 is made larger than that of a slurry pipe, the coarse particles are easily precipitated on the lower part of the coarse particle removing tank 20 and the separation of fine particles therefrom is accelerated. The coarse particles carried out by the screw feeder 11 are transferred to the outside, the degree of the coarse particle deposition is detected by a level meter 16 and valves 15a and 15b can be automatically operated. When a wire netting 5 is clogged with the coarse particles, a jet of water is directed toward the clogged parts from a high pressure water spray opening 14 to effect back washing so as to free the clogged parts.

Title: Continuously jetting ink jet recorder
Inventor: MUTO MASAYUKI
IPC: B41J2/125
Filed: 1992-02-24
Abstract: PURPOSE:To detect a position of an ink jet shaft (nozzle shaft) in a simple and easy manner with high accuracy. CONSTITUTION:Ink jetted out of a nozzle 1 is divided into a series of ink particle trains. A control electrode 3 electrifies the ink particles by a dc test voltage, which is about one-half of a control voltage at the time of recording and applied from a dc power source DCS. A deflecting electrode 7 forms a deflection electric field orthogonal to an ink jet shaft to deflect the electrified ink particles as well as electrifies the ink particles splashed by the collision with the tip end of a knife edge 5 to a reversed polarity. A conductive particle catcher 8 catches the ink particles which have not been cut by the knife edge 5. An electric current/voltage conversion circuit CD detects the electric charge on the caught ink particles. Based on the detected electric charges, a polarity discrimination circuit PD judges whether the ink jet shaft is ideally adjusted. Based on the judged result, the ink jet shaft (nozzle shaft) is adjusted by an adjusting screw 13.

Title: Ball joint
Inventor: KOGA HIRONORI
IPC: F16C11/06
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To facilitate assembly of a spring material having a slipping-off preventing function by arranging a vertical part extending a housing inner circumference recessed part from an inner circumferential side to an outer peripheral direction, and providing a taper part inclined to an opening side from the inner circumferential side to a parallel part side on the vertical part which is constituted by the parallel part for connecting the vertical part and which is arranged adjacently. SOLUTION: A ball stud to which a bearing 5 is inserted from one opening 9 of a housing is inserted, a spring material 14 is press fitted by a jig 30. The jig 30 is provided with a part 31a inclined from an inner circumferential side to an outer peripheral side, and the spring material 14 is push-pressed by its outer peripheral side end part 31b. In this case, the diameter of a large ring part 14a of the spring material 14 is contracted smaller than that of an inner circumference of the housing by a guide member. When the large ring part 14a exceeds an inner circumference recessed part 10, a vertical part 10a arranged on an adjacent opening 9 side is provided with a taper part 11 inclined to the adjacent opening 9 side from the inner circumferential side toward a parallel part 10b side.  Since a slight part is brought into contact with the large ring part 14a and abrasion resistance is small, the diameter of the large ring part 14a is expanded. It is thus possible to provide a slipping-off preventing effect easily.

Filed: 1994-04-12
Abstract: PURPOSE:To obtain stable tape tension without providing a tension lever. CONSTITUTION:A tape state medium 101 is sent by a tape transferring means 1 with fixed speed. A wound diameter detecting circuit 40 obtains wound diameter information of the tape state medium 101 wound on a reel 2. A back torque operation circuit 5 outputs a signal proportional to an output of the wound diameter detecting circuit 40. A sine wave pattern generating circuit 9 outputs a signal having a sine wave pattern synchronized with an output of a pulse generator 8. A speed control circuit 13 outputs a signal so as to remove an output of a speed error detecting circuit 12. An adder circuit 10 outputs a synthetic signal of output signals of a back torque operation circuit 5, a sine wave torque generating circuit 9 and a speed control circuit 13. A driving circuit 6 generates torque in a motor 7 based on an output of the adder circuit 10, and gives tension to the tape state medium 101. At the time, variation of tension of the tape state medium 101 is suppressed by setting a phase and amplitude of variation pattern of the sine wave pattern generating circuit 9 so as to cancel intrinsic torque variation of the motor 7.

Filed: 1988-03-28
Abstract: PURPOSE:To actualize the title package at low cost using an air bridge structure by a method wherein, after bonding a foaming resin onto inner wiring parts, a semiconductor device is packaged by molding it out of resin. CONSTITUTION:First, the whole surface of inner wiring parts is covered with a foaming resin 5. This foaming resin 5 is foamed by adding a foaming agent to polyolefin, epoxy etc., to be bonded onto the whole surface of the inner wiring and then set as it is in the foaming state. Resultantly, the foaming resin 5 in the foaming state permeates into the parts below respective wirings 3b, 3a so that the space 4 at the junction of the upper wiring 3b and the lower wiring 3a may be filled with the foaming resin 5 mostly comprising bubbles 5a. Consequently, said space 4 is secured of an air layer comprising the bubbles 5a. Then, a semiconductor device whereto the foaming resin 5 is bonded and set is molded out of another resin 6 to finish the packaging process of the semiconductor device. Through these procedures, the package can be actualized at low cost without notably increasing the parasitic capacity between the inner wirings 3b and 3a.
