IPC: G06F13/00
Filed: 1981-12-26
Abstract: PURPOSE:To prevent the interference of data transmission between circuit networks, by providing a connection means where data are not interferred among bus circuit networks by the mutual connection of the networks and the data transmission among the networks is not delayed. CONSTITUTION:Data transmission speeds among stations A-E on a bus 1 and among stations F-K on a bus 2 are assumed both as X mega-bit/sec and the data transmission speed between one of the stations A-E on the bus 1 and one station F-K on the bus 2 is assumed as Y mega-bit/sec. A band pass repeater BR blocks the data in the X mega-bit/sec and relays only the data in the Y mega-bit/sec. Then, the bs circuit network belonging to the bus 1 or 2 can act like independent circuit networks, and when mutual communication is required, the networks operate as if they were a bus.

Title: Valve device
Inventor: IZUMI KOJI
IPC: F16K1/44
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent generation of rotational force due to turbulence of fluid in a plug so as to prevent damage in a plug system and in an operation device system by forming a plug so as to provide an elliptical cross section and arranging the plug inside a valve casing so that its major axis direction is set in the direction along the flow of the fluid. SOLUTION: In a flow rate controlling double seat valve, when upper and lower plugs 9, 10 are lifted so as to open a valve, fluid flowing into a primary side flow passage 6 is divided into upward fluid, which is directed to an upper side flow passage 7a, and downward fluid, which is directed to a lower side flow passage 7b, in a secondary side flow passage 7, and then, the divided flows are converged together in a flow outlet 3 so as to be discharged. In this case, each of the upper plug 9, the lower plug 10, and an inter-plug joint part 11 constituting a plug 8 is formed into a shape provided with an elliptic cross section. In addition, each of them is arranged inside a valve casing 1 so that its major axis direction is set in the direction along the flow of fluid in the valve casing 1.  In this way, the plug 8 is prevented from turning because of application of force due to turbulence of the fluid, so that damage in a connecting joint part and the like between a valve shaft part 12 and a plug stem 15 can be prevented.

Title: Developing device
Inventor: KANAI HIDEFUMI
IPC: G03G15/08
Filed: 1986-09-08
Abstract: PURPOSE:To maintain magnetic particle-containing concentration in a developer within a fixed range by setting the magnetic force of magnetic particles to 1.2-1.8 times the magnetic force of high-resistant magnetic toner. CONSTITUTION:An electrostatic latent image is formed on the surface of an image carrier 1 and developed with toner by a developing device 4 having a developer 4b containing high-resistant magnetic toner and magnetic particles having almost the same particle size as that of the high-resistant magnetic toner and resistance lower than that of the high-resistant magnetic toner and receiving bias voltage. The magnetic force of the magnetic particles is set to 1.2-1.8 times the magnetic force of the high resistance magnetic toner. Consequently, the toner concentration in the developer 4b is automatically maintained within the prescribed range and always excellent images can be obtained. Since it is unnecessary to form a concentration detecting means or the like for controlling the concentration, an inexpensive developing device can be obtained.

Title: Resin bearing
Inventor: TSUTSUI NORIHISA
IPC: F16C33/12
Filed: 1987-08-25
Abstract: PURPOSE:To obtain a resin bearing having excellent abrasion resistance and friction resistance by employing a porous structure having hole portions for the resin bearing and filling the hole portions with oil.

Title: Method for controlling oxygen concentration sensor
Inventor: KAWANABE TOMOHIKO
IPC: F02D41/04
Filed: 1985-09-25
Abstract: PURPOSE:To prevent a blackening phenomenon and to make it possible to rapidly discriminate an air/fuel ratio after the supply of a current to a heating element was reopened, by stopping the supply of a current to an oxygen pump element when engine load is present in a predeter mined high load region and stopping the supply of a current to the heating element when the operation in the predetermined high load region continues for a predetermined time or more. CONSTITUTION:An air/fuel ratio control circuit 32 discriminates whether the number of rotations of an engine from a rotation sensor 28 are present in a predetermined high load region. When said number of rotations are present in the high load region, the supply of a current from a pump current supply circuit 35 is stopped to prevent the generation of a blackening phenomenon and the deterioration of the oxygen pump element in an oxygen concn. sensor 30 is prevented. When an operation state such that engine load belongs to the predetermined high load region is continued after a predetermined time, the circuit 32 reduces or stops the supply of a current to the heating element from a heater current supply circuit 36. Therefore, this method is different from such a method that the supply of a current is always stopped when an engine load is present in the high load region and an air/fuel ratio can be rapidly and accurately discriminated from the ouptu level of the sensor 30 even after the supply of the heater current is resumed.

Filed: 1981-12-25
Abstract: PURPOSE:To detect the tip of steel material quickly and accurately by setting a threshold level from a noise signal before the passage of the steel material from an accelerometer provided on a bearing of a conveying roller. CONSTITUTION:An output of acceleration 3 is taken out when a conveying roller 4 reaches specified revolutions thereof while the lifting, turning and rotating thereof are completed before the tip of a steel material 1 reaches the roller 4. This output is fed to a peak value hold circuit 9 as noise signal transmitted from an accelerometer 3 before the passage of the steel material. Based on an output L0 of the hold circuit 9, a threshold level La is set for a comparator 10. As soon as the tip of the steel material comes in contact with the roller 4, an output P of the accelerometer 3 is generated to the comparator 10. Thus, the tip  of the steel material can be detected quickly and accurately.

Title: Bit line load circuit of semiconductor static ram
Inventor: KADOTA JUNJI
IPC: H03K3/356
Filed: 1992-08-10
Abstract: PURPOSE:To quickly lower potential of bit line during read operation and thereby raise a read rate by using bit line level compensation N channel transistor. CONSTITUTION:When a word line WL is selected in accordance with an external input address signal, data held in a storage cell 2 is transferred to a bit line D and an inverted line D through switching transistors N1, N2. Since this potential is precharged previously up to power supply voltage VCC in accordance with a precharge signal PHIP before the potential of the word line WL is raised, any one of the bit lines D, inverted line D is reduced from the potential VCC with an information of the cell 2. In this case, the bit line level compensating transistors N7, N8 are in the non-conductive condition, when its threshold voltage is VT, because the potential of the line D and inverted line D are lowered to VCC-VT and become conductive. Accordingly, the potential of the line D is quickly lowered. When it is lowered to VCC-VT', the transistor N7 becomes conductive and the potential of the line D is not lowered up to the ground potential.
