Abstract: PURPOSE:To provide circuit constitution capable of attaining 3V resistance between the gate-source, gate-drain and gate-substrate of all transistors (TRs) in a semiconductor manufacturing process in a signal voltage level converting circuit for converting an input signal with 0 to 3V narrow logical amplitude into an output signal with 0 to 5V wide logical amplitude. CONSTITUTION:Voltage impression to TRs Q1, Q2 is eased by including TRs Q11, Q21 in a bias circuit. On the other hand, voltage impression to TRs Q7, Q8 is eased by including TRs Q71, Q79 in an output buffer circuit 3. An input signal Vin with 0 to 3V voltage is temporarily converted into a bias signal Vin' with about 3 to 5V voltage and then the signal Vin, is converted into an output signal Vout with 0 to 5V voltage. Consequently the gate-source, gate-drain and gate-substrate of all TRs can be set up to not 5V resistance but 3V resistance.

Title: Electric field emitting electron gun
Inventor: OBARA KENJI
IPC: H01J37/248
Filed: 1989-11-17
Abstract: PURPOSE:To prevent damage of an emitter by coating a conductive member on a part opposite to an acceleration electrode of an extracting electrode via an insulating member, and making the conductive member and the emitter the same potential. CONSTITUTION:An extracting electrode 2 is placed in the vicinity of an emitter 1, a conductive member 7 is coated on a part opposite to an acceleration electrode 3 of the extracting electrode 2 via an insulating member 6, and the conductive member 7 and the emitter 1 are made to have same potential. As a result, when an electric discharge occurs between the acceleration electrode 3 and the conductive member 7, the potential of the emitter 1 also rises temporarily to a potential of the acceleration electrode 3. In the meantime the potential of the emitter 1 becomes positive with respect to the potential of the extracting electrode 2 so that generation of electrons from the emitter 1 can be temporarily stopped and excessive electron emission between the emitter 1 and the extracting electrode 2 can be prevented. Thus damage of the emitter 1 can be prevented.

Title: Pump piping system for steam power generating station
Inventor: KOBAYASHI NOBUYOSHI
IPC: F04B49/06
Filed: 1988-11-29
Abstract: PURPOSE:To eliminate the need for pressurizing pump equipment for a branching line so as to reduce the power loss by controlling the speed of a variable speed pump such that the flow rate of the main supply line may become larger than the demand and the pressure in the branching line also larger than a predetermined value. CONSTITUTION:The flow rate demand in the main supply line 2 is controlled by modulating the speed of a variable speed pump 1 through a flow rate setting unit 3 and a speed controller 4. Where a branching line 5 is used, the speed setting signal is outputted from a speed setting unit 8 through a required pressure setting unit 7 so that the branching line may yield the demanded pressure. Since a high value selector 9 compares the speed setting signal demanded by the branching line with the speed setting signal demanded by the main supply line 2 and selects whichever is higher, the variable speed pump 1 is set to conform to the higher speed demand. Where the branching line 5 is used, a comparison is made with the speed setting signal required for the demanded pressure, and, if the speed demanded by the branching line 5 is higher, the speed is controlled to that which is demanded by the branching line 5.

Title: Centripetal type air blower
Inventor: KONDO RYUTA
IPC: F04D17/02
Filed: 1988-11-28
Abstract: PURPOSE:To aim at improving efficiency in a low flow area by disposing an impeller provided with back flow preventing walls at the tip edge in a bellmouth opening to sub-guide plates and positioning the intake side region of the impeller in a ventilation flue. CONSTITUTION:When a motor 20 is driven in an unloaded condition so as to rotate an impeller 17, air flow W inhaled in the radial direction through guide vanes 19 from a ventilation flue 14 between a main guide plate 11 and a sub-guide plate 13 is discharged in the axial or diagonal direction while being accelerated by each blade 15. On the other hand, if the flow is contracted by enlarging the load, the influence of centrifugal force becomes large, and air flow which is going to flow out in the peripheral direction is generated in the blades 15. However, since back flow preventing walls 18 provided approximately at right angles to the blade surfaces exist at the tip edges, the air flow flowing outside the impeller 17 is obstructed, and the air flow leaked out of the back flow preventing wall 18 is arrested at the guide vanes 19 in the intake catchment area. As a result, a stable operating region can be ensured even in the low flow area, and high static pressure can be obtained as well as a stable centripetal flow can be maintained simultaneously.
