Title: Corrosion suppressing apparatus for vertical-shaft pump
Inventor: ISHIKAWA YOSHIHIDE
IPC: F04D7/06
Filed: 1983-08-31
Abstract: PURPOSE:To permit perfect suppression for corrosion by installing an airtight outer cylinder in the outer periphery of a vertical-shaft pump and discharging each liquid in the pump and in the space between the pump and the outer cylinder, by the aid of air, permitting the inside and the outside surfaces of the pump to be perfectly dried when the pump is in rest. CONSTITUTION:In a pump 5 installed in a water pumping up tank 2, the discharge valve 1 is perfectly closed when the pump stops operation, and air is supplied into the pump through an air pipe 6 from an air tank 13 by opening a valve 10, and the liquid in the pump is removed, and air is supplied into the airtight outer cylinder 4 installed in the outer periphery of the pump from the air tank 13 through an air pipe 7 by opening a valve 9, and thus the liquid on the outer peripheral surface of the pump is removed. Therefore, deterioration of the inner and outer surfaces of the pump can be prevented by covering the outer and inner peripheral parts of the pump by an air layer.

Filed: 1978-12-19
Abstract: PURPOSE: To obtain a developer superior in developing performance and durability, and capable of forming a high density image, by dispersing into a carrier fluid, carbon black or an organic pigment coated with a silane coupling agent.  
     CONSTITUTION: Carbon black, such as furnace black or acetylene black, or an organic pigment, such as phthalocyanine blue or rhodamine lake is added to the solution of a silane coupling agent (an organic silicon compound, i.e. silicone, having a reactive group), such as vinyl trichlorosilane or vinyl triethoxysilane to wet the black or pigment. After this is properly dispersed, the solvent is evaporated and heat treated at about 100W120°C to form a toner coated with a silane coupling agent. Then, this toner is dispersed into a carrier fluid, such as n-hexane or ligroin, having high insulating property (resistivity 10 9 Ωcm or more) and low dielectric constant (3 or less) to form a developer.

Title: Request cancel processing system in advance control processing
Inventor: MASUZAWA HIDEHO
IPC: G06F3/00
Filed: 1977-12-27
Abstract: PURPOSE: To utilize a re-transmission request signal line to make a cancel signal line needless when an access request issued previously from a data transmission-side processing unit is cancelled in the advance control system of the I/O system of the data processing system.  
     CONSTITUTION: When the priority level determination between channel unit CU8-0 and other CUs in UI (unit interface) unit 7-0 which accepted request RQ from CU8-0 results in selecting CU8-0, unit 7-0 issues request REQ' to BI (bus interface) unit 6. Unit 6 determines a priority level and selects unit 7-0. CU8-0 performs advance control by transmitting address information and data. When an error exists in address information, etc., unit 6 issues a re-transmission request through re-transmission request signal line 9-0. Unit 7-0 checks the validity of data which is accepted at timing T 6 ; and in case of error, unit 7-0 issues a cancel signal for cancelling request REQ' through signal line 9-0 as shown by the thick-line arrow. As a result, the number of signal lines can be reduced, and the transfer processing time can be obtained.

Title: Image forming device
Inventor: IWAO NAOTO
IPC: G03G15/08
Filed: 1989-06-21
Abstract: PURPOSE:To simplify the whole mechanism of a developing device and to miniaturize an overall image forming device by providing ultrasonic piezoelectric transducers as a selective driving means and guide members attached in the selective driving directions of developing units. CONSTITUTION:The subject device is provided with the ultrasonic piezoelectric transducers 2 as the selective driving means of the developing units 31 - 34 and the guide members 5 attached in the selective driving directions of the developing units 31 - 34. When a prescribed electrical signal is applied to the ultrasonic piezoelectric transducers 2, an elliptical vibration occurs on the prescribed vibration surfaces of the ultrasonic piezoelectric transducers 2 and the developing units 34 - 34 are directly driven by the elliptical vibration. Consequently, a speed reducer which converts the output of an electromagnetic motor to slow-speed, high torque and a motional direction converter which converts a rotary motion to a linear motion are not needed. Thus, a developing device is simplified, and the whole of an image forming device is easily miniaturized.

Title: Call restriction circuit for telephone set
Inventor: SUZUKI MASAHARU
IPC: H04M1/673
Filed: 1987-06-25
Abstract: PURPOSE:To allow only a possessor of a key to release the restriction of a call by using a lock means provided to a telephone set to restrict the calling. CONSTITUTION:When a nonmagnetic member 12 interrupts a magnetic circuit between a magnet M1 and a reed switch RS, since the reed switch RS remains opened, a reference potential point is not connected to a reset terminal T2. Thus, even when a ten-keys is operated, the dialer IC7a is inactivated and the call is restricted. On the other hand, in turning a key LOCK 1 clockwise, a nonmagnetic member 12 is turned to form a magnetic circuit to the reed switch RS by a magnet M1. When the magnetic circuit is formed, reeds RSa, RSb are closed and a reference potential point is connected to a reset terminal T2. Thus, the dialer IC7a is active to release the call restriction.

Title: Load follow up operation system for nuclear power plant
Inventor: SAKAMOTO YASUNORI
IPC: G21D3/12
Filed: 1987-06-26
Abstract: PURPOSE:To improve profitabilily by executing load follow up by a power decrease operation, power increase operation or power level operation by compensating the xenon concn. after power alteration by controlling the controlling rod and controlling the flow rate in the reactor core within prescribed range. CONSTITUTION:The reactor core flow rate id decreased to and the power is lowered down to the target low level power in the case of carrying out the power decrease operation in this operation method. Insertion of the control rod is executed only when the power does not lower down to the target level even if the reactor core flow rate attains the lower limit value permitted down to the low power level. The reactor core flow rate is then increased up to the flow rate 2e of the lower limit at the high power level in the case of carrying out the power increase operation. The operation returns to the high power operation point 14 of nearly the same power and flow rate state as the power and flow rate state before the power decrease when the power is increased by increasing the flow rate from the low power operation point 13. The xenon concn. decreases sharply after the high power level is reset in such a manner. This decrease is compensated by insertion of the control rod. The load follow up operation is thus executed in the state of the low reactor core flow rate and, therefore, the accumulation quantity of Pu increases and the economic efficiency improves.

IPC: H04M3/00
Filed: 1987-06-26
Abstract: PURPOSE:To easily cope with various subscriber line signal systems by generating a pulse having a width corresponding to a signal from a subscriber line or the like and measuring the pulse width by means of the program control. CONSTITUTION:A subscriber line signal input conversion section 13 converts a DC signal level from a telephone set into a signal level of a CPU section 11 from a telephone set and inputs the result to a CPU 11 via an input line 14. The CPU section 11 uses a program stored in a ROM section 12 to discriminate a sent signal (cut-off or calling or the like) to generate a pulse of a corresponding time width based on the result of discrimination and sent to a carrier device signal output conversion section 16 via an output line 15. The conversion section 16 converts the sent signal to a level suitable for the carrier equipment and gives an output to a common section. Moreover, the signal from a carrier equipment signal input conversion section 17 is processed nearly similarly and outputted to a subscriber line signal output conversion section 20.
