Filed: 1983-12-19
Abstract: PURPOSE:To achieve a large capacity, low-pressure loss prevention, high pressurization and reduction of operating force by providing a control spool and an opposed piston in the lower end of an operating force reduction rod which generates a downward force. CONSTITUTION:When a control lever comprising a control knob 1 and a lever 2 is tilted, an operating force reduction rod 21 is displaced downward, and at the same time, a return spring 10 is compressed, and a spool 8 is also displaced downward as a pressure regulating spring 9 is compressed. When a pressure is applied to a load connected to a secondary pressure port A, a proportionate pressure is applied to a secondary port 24 to disconnect a supply port 11 and a supply port P when a state of balance with the force of the pressure regulating spring 9 is reached. Since the same pressure is being applied to a piston 22 of the operating force reduction rod 21 at this time, a force equal to that which moves the spool 8 upward is being generated as a force that moves the piston 22 downward.

As to toner cartidges 24a for red and black toner components, the positions of an aperture 31a and a blocking plate (not shown) are also inverted on the right and left sides. At the time of replacing the developing unit, a reed switch commands a control circuit to switch electromagnetic clutches 33, 34 and drive a rotary solenoid 17. The solenoid 17 rotates a 2nd toner guide part 16 to a driving position as shown by an alternate long and short dash line, guides the toner scraped from a photosensitive drum 4 into a toner collecting room 14 and recovers the toner to a toner feeding part 2 through a carrying spiral 19. Thus, the toner color can be replaced only by replacing the developing unit.

Title: Sedimenting and hardening additive and method
Inventor: TAGUCHI YOSHIO
IPC: C09K17/48
Filed: 1994-09-07
Abstract: PURPOSE: To obtain certain support force inexpensively by simple short-time work when soil particles on the bottom of the water are hardened and to prevent the generation of environmental pollution such as the contamination of water. CONSTITUTION: A sedimenting and hardening additive consists of aluminum sulfate, calcium sulfate, potassium carbonate, sodium carbonate and citric acid. The sedimenting and hardening additive and cement are mixed with soil particles high in water content ratio such as dredged building sludge or soft soil under stirring to be thrown in water.

Title: Copper conductor paste and multilayer ceramic substrate
Inventor: SUNAHARA KAZUO
IPC: C09D5/24
Filed: 1988-09-27
Abstract: PURPOSE:In copper conductor paste which contains copper, to prevent solder wettability by adding metallic hydride. CONSTITUTION:Metallic hydride is added to copper conductor paste to be used in manufacturing of a multilayer ceramic substrate, and even if it is baked in the nitrogen atmosphere of several hundreds ppm in oxygen concentration, the surface of the copper conductor is not oxidized after baking, and organic vehicle within copper conductor paste can be removed completely. The metallic hydride is not limited especially so long as it is a metallic hydride which has a property of reducing the surface of a copper conductor when forming the copper conductor by baking it in the nitride atmosphere of several hundreds ppm in oxygen concentration. It is to be desired that such metallic hydride should be added to be 0.05-10% in total amounts of conductor paste. If the amounts of additional metallic hydrides are below 0.05%, the effect by the addition is small, while if it exceeds 10%, the degree of sintering of copper powder lowers and it causes the lowering of peel strength, so both are not preferable.

Title: Differential input circuit
Inventor: MUROTA KAZUAKI
IPC: H03G3/20
Filed: 1992-09-08
Abstract: PURPOSE:To reduce cost by improving the versatility of the differential input circuit, which is used for the input step of an operational amplifier or a comparator, corresponding to an in-phase input voltage range. CONSTITUTION:A differential pair 33 composed of NPN transistors TR1-TR4 and a differential pair 34 composed of PNP transistors TR11-TR14 are integrated into a common integrated circuit 32. When the voltage level of an input terminal P2 is higher than a reference voltage Vref 2, a comparator 39 discriminates the level of an input signal by conducting a switch S1 and energizing power to the differential pair 33 and when the level is lower than the Vref 2, the level of the input signal is discriminated by conducting a changeover switch S2 and energizing power to the differential pair 34. Thus, since the respective differential pairs 33 and 34 are selectively used corresponding to an in-phase input voltage range Vcm, a differential input circuit 31 can be used over a wide input range from a voltage Vcc to a voltage Vee, the versatility can be improved, and the cost can be reduced.

Abstract: PURPOSE:To enable calculation using an execution address due to remainder calculation using a module by providing an address conversion part to change a real access address for each module according to a parameter value set in advance. CONSTITUTION:An address conversion part 8 inputs a data signal 14, address signal 20 and set control signal 40 and executes the calculation of conversion from the address, which is inputted from the address signal 20, to the address to be really accessed for each module.

Accordingly, even when data are stored in structure for easily referring the memory from a host, in the processing mode, the efficient calculation can be executed by using the execution address due to the remainder calculation using the modulo.
