Title: Agc circuit
Inventor: MASUKO AKINOBU
IPC: H04N7/16
Filed: 1986-05-12
Abstract: PURPOSE:To apply optimum gain control to an input signal by decreasing a RFAGC time constant when a voltage change in a RFAGC is a prescribed level or over and increasing the time constant when the change in the RFAGC voltage is small conversely. CONSTITUTION:When a change in the RFAGC voltage exceeds a diode voltage (VF), diodes D1, D2 are conductive. The time constant of a time constant circuit connected to the output of an RFAGC circuit 60 is nearly (C10+C30).R10. When the voltage change is less than the diode voltage, the diodes D1, D2 are turned off and the time constant is nearly (C10+C3O).(R10+R30). Since a high resistance is selected for the resistor R30, the time constant is increased. When the RFAGC voltage exceeds the diode voltage, the diode D2 is conductive and when the voltage is decreased less than the diode voltage conversely, the diode D1 is conductive. Thus, a time constant control means 70 controls the RFAGC time constant in response to the change in the RFAGC voltage. Even when several lines of horizontal synchronizing signals are missing, the IFAGC voltage is stabilized.

IPC: F25D3/10
Filed: 1989-04-28
Abstract: PURPOSE:To increase stability and get big mechanical strength by making uneven the face of a surrounding high purity aluminium side and covering with a copper band in which holes for flow of refrigerant are made at fixed intervals and angularly molding it. CONSTITUTION:A copper band 5 is installed around an aluminium stabilized super-conducting wire 1, this copper band 5 is angularly molded and a plurality of flow ports 6 of refrigerant are made at almost fixed intervals in a corner portion. A projecting portion 7 is worked at the inside of the copper band 5 or at the side of the aluminium stabilized subconducting wire 1; and a recessed space 8 made thereby is filled with refrigerant 9 through the flow ports 6 of refrigerant. As copper is a metal whose electric resistance is low, Joule heat is made small, and as the flow ports 6 of the refrigerant 9 are made in the copper band 5, the refrigerant 7 can freely go in and out of the space between the copper band 5 and the aluminium stabilized superconducting wire 1. Thereby, it is possible to increase the mechanical strength of the conductor which higher superconducting stability is kept.

Filed: 1987-04-30
Abstract: PURPOSE:To reduce a loss of optical coupling by converting an electric signal obtained by applying a light beam from an emitting end face to photoelectric conversion, to an optical signal. CONSTITUTION:An optical signal from a multi-mode optical fiber 7 is converted to an electric signal by a photodiode PD1. The light receiving surface of the PD1 is larger enough than the core diameter ( 50mum) of the fiber, and no loss is generated therein. An electric signal of a multi-mode, which is applied with photoelectric conversion is sent to a driving circuit 2 from a light receiver 1, by which a laser diode ID is driven to emit a light beam by a single mode. Th light emitting end face of the ID can be made smaller enough than the core diameter ( 10mum) of a single mode optical fiber 8. In such a way, by using an optical system such as a lens, etc., an optical signal of a single mode can be coupled to the optical fiber 8 at a low loss.

Title: Ball-and-roller bearing
Inventor: BAANHARUTO BOIERU
IPC: F16C17/04
Filed: 1990-04-25
Abstract: PURPOSE: To reduce cost and to facilitate handling by providing inner and outer rings with flanges, forming a lubricant groove radially from the inner or outer peripheral surface of each flange, making the groove shift to another radially oriented shallow groove, and forming the crest and root of a corrugation in the other groove. CONSTITUTION: A shallow groove 10 is formed in a circumferential part of a thrust surface 8 and extends the overall radial width of the end face 7 of an inner ring 3. Next, a deep groove 9 is laid and embossed over the range of the groove 10 starting from the outer peripheral surface 11 of a flange 4 provided at the inner ring 3. The groove 9 has a bottom face 12 tilted at an angle α to the end face 7 and extends to the thrust surface 8. During operation, lubricant passes through a gap 16 between the flange 2 of an outer ring 1 and the flange 4 of the inner ring 3, flows into the groove 9, reaches the root 15 of the groove 10, and leads to the thrust surface. In that case, the lubricant produces dynamic pressure through relative movement to a machine element (not shown in the figure) in the groove 10 to bear an axial force.  During inoperative time, the inner ring can be removed by inserting the tip of a tool into the groove 9.

Title: Manufacture of lead frame
Inventor: SUZUKI MICHIYOSHI
IPC: H01L21/48
Filed: 1986-05-13
Abstract: PURPOSE:To increase inner leads without enlarging a lead frame, by forming inner lead intervals in patterns to be transcribed on both resist layers put on the front and back surfaces of a conductive plate so that they become larger on the side of the back surface to form narrow leads there. CONSTITUTION:Negative-type photo resists 42 are formed in their similar thickness on the front and back surfaces of a 42-alloy plate 40. A front plate 44 having windows 45, and a back plate 48 having windows 49 are closely attached to the resists 42, to form masks by exposure developing. When both surfaces are etched by using FeCl3 solution, inner leads 60 are formed so as to be inserted between resists 52 and 54. Then, undercuts 56 and 58 are generated on the width-directional end parts of respective upper and lower ends in the inner leads. Width between the front surface 62 and the back surface 64 in the inner lead 60 is smaller than that between the resists 52 and 54. With the resists being dissolved and removed, rinsing and drying processes are performed for completion. Because intervals between leads become large, the lead terminals can be increased without enlarging the lead frame.

Abstract: PURPOSE:To perform solid/liquid separation of activated sludge of high concentration securely by subjecting slurry of activated sludge to aeration to cause foam generation in a biological treatment combined with solid/liquid separation stage, and recycling the scum sticking to the foams to a biological nitration and denitrification treatment stage. CONSTITUTION:Residual solid is removed from night soil 1 and the night soil 1 is fed to a denitification tank 2 in a biological nitration and denitrification treatment stage together with recycled nitration liquid 3 without diluting the night soil. The liquid in the tank 2 is flowed into a nitration tank 4, aerated by the air 5. Activated sludge slurry 8 flowed out of the nitration tank 4 is fed to a high degree biological treatment tank 9 serving also as a solid/liquid separation tank 9. Nitrate nitrogen or nitrite nitrogen contained in the activated sludge slurry 8 is denitirified biologically in the solid/liquid separation tank 9, and foam generation is caused violently by blowing air to form a scum layer 11 comprising activated sludge sticking to foams. Since the concn. of the sludge in the scum layer 11 is so high as 4-5%, the scum is recycled to the nitration tank 4.
