Title: Electric control device for hydraulic circuit
Inventor: KASAI MASUO
IPC: F15B9/09
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To provide an electric control device for a hydraulic circuit to improve responsiveness and realize stable control characteristics without arranging a control valve being of special structure. SOLUTION: In a flow control valve 2 and a hydraulic motor 4, a dead zone estimating circuit 16 outputs a positive dead zone width estimated value Dp or a negative dead zone width estimated value Dm to a dead zone compensating circuit 12 from a relation between an input current (i) and a present speed signal Vc according to a mathematical model format according to which a dead zone is determined. The blind sector compensating circuit 12 selects either a positive dead zone estimated value Dp or a negative dead zone estimated value Dm and adds it to a control command signal Iin to output an output signal Iout by a dead zone compensating circuit 12 based on a code for a control command signal Iin. A hydraulic motor 4 is driven by means of a drive flow rate (q) according to an input current (i) responding to the output signal Iout.  Further, in addition to dead zone compensation described above, by determining the control command signal Iin through feedback of a present speed signal Vc , feedback correction is also simultaneously performed.

Title: Interface circuit
Inventor: KITAMURA SHOZO
IPC: G06F3/12
Filed: 1988-06-22
Abstract: PURPOSE:To always enable only either a TTL signal reception circuit part or a differential signal reception circuit part to be packaged and to reduce power consumption by providing the TTL signal reception circuit part and the differential signal reception circuit part on respective independent sub base, respectively, and connecting them to an interface circuit loadably/unloadably freely. CONSTITUTION:When the signal format of an interface is a TTL signal level, the sub base 3A for TTL signal is loaded on the interface circuit 1A via connectors 30 and 31. A signal outputted from a parallel interface connector 10 passes the connector 30, the TTL signal reception circuit 11A, and the connector 31, and is inputted to an MPU for control via an I/O port 12. On the other hand, when the signal format is a differential signal level, the sub base 3A is removed, and the sub base 3B for differential signal instead of it is loaded. The signal inputted to and outputted from the connector 10 passes the connector 30, and is converted to the TTL signal level by the differential signal circuit 11B, and is connected to the interface circuit via the connector 31 similarly as the TTL signal level.

Title: Ventilating fan controller
Inventor: UEKI AYUMI
IPC: F24F7/007
Filed: 1984-07-23
Abstract: PURPOSE:To enable a ventilating fan to be started by a maximum electric power, by providing, to opposite sides of a variable resistor for adjusting a phase angle, a relay switch that can be turned on or off by a relay driven by a timer circuit. CONSTITUTION:When a switch 102 is turned on, an electric current flows through a motor 103 of a ventilating fan, a relay switch 3 and a resistor 106 to a condenser 108. The voltage of the opposite ends of the condenser 108 immediately reaches the breakover voltage of a diac 107, the condenser 108 discharges through the diac 107, and a triac 104 becomes conductive. When a certain period has passed from the application of the electric power, the relay 2 is actuated by a timer circuit 1, and the relay switch 3 is driven to open. As a result, the conduction of the triac 104 is made by the condenser 108, the resistor 106 and a variable condenser 105 for adjusting a phase angle. As the ventilating fan is started by a maximum electric power, a trouble of an electric sound from the ventilating fan at the start of its operation can be freed, and the ventilating fan can be started even when air is blowing reversely.

Title: Manufacture of alkaline battery
Inventor: NAGAMINE AKIO
IPC: H01M6/12
Filed: 1981-09-28
Abstract: PURPOSE:To prevent bulging of a battery due to hydrogen gas evolution after assembling and to increase a storage life by improving a filling process of a zinc electrode into a negative container. CONSTITUTION:A positive black mix 2 is placed in the bottom of a positive container 1 which also acts as a positive terminal. A separator 3 is stacked on the black mix 2. An open end 1a of the container 1 is sealed with a negative container 5 which contains a zinc negative electrode 4. In a filling process of the negative electrode 4 into the negative container 5, metal mercury is dropped onto the copper surface of the negative container 5, which brings it into contact with the zinc negative electrode 4, then the zinc negative negative electrode 4 prepared by mixing zinc powder and a gelling agent is filled and an alkaline electrolyte is poured. Because a large amount of mercury exists on the copper surface of the negative container with the alkaline electrolyte, the copper surface is quickly amalgamated. Zinc powder is also amalgamated quickly because it brings into contact with mercury in the alkaline solution. As a result, hydrogen gas evolution from both the copper surface of the negative container 5 and zinc powder can be prevented, and the bulging of a battery even after long period of storage can be prevented.
