Abstract: PURPOSE:To recover molds by using traveling properties of molds, and to prevent damage of thin membrane by setting a liquid pressure controlling device for feed solution, by laying the thin membrane to pass the molds in a container and chambers having inlets and outlets, respectively, on both the sides of the membrane, feeding solutions having different substrate concentrations from the inlets of both the chambers and discharging them from the outlets. CONSTITUTION:The porous thin membrane 2 is set in the main body container 1 of a mold recovering device. The first and the second chambers 3 and 3a divided by the thin membrane 2 are set. The waste solution B having a low substrate concentration and the molds Z having finished the reaction is fed from the branched pipe 24a of the pressure damper 20a through the liquid chamber 22a and the inlet 6 to the second chamber 3a. On the other hand, the reaction solution A having high substrate concentration and the molds Z is fed from the branched pipe 24 of the pressure damper 20 through the liquid chamber 22 and the inlet 4 to the first chamber 3. Since both the solutions A and B have big difference in substrate concentration, the molds are passed through the thin membrane 2 and recovered at the solution A side having high substrate concentration. The gas pressure in the gas chambers 21 and 21a of the pressure dampers 20 and 20a is controlled by the control valves 31 and 33 and the gas bomb 32, and pressure at both sides of the thin membrane 2 is balanced to prevent damage.

Title: Cylinder direct injection internal combustion engine
Inventor: KANO MASAO
IPC: F02P5/15
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To enable large amount of internal EGR, without using an external EGR system in a spark ignition type cylinder direct injection internal combustion engine. SOLUTION: A sub injection 5 is executed in the cylinder, in response to a command of a controller for mixing with a combustion gas of a high oxygen concentration near top dead center from the final stage of an exhaust stroke to the initial stage of an intake stroke in a stratified-charge combustion run or a uniform lean run. A sub ignition 6 is executed by a spark ignition plug for generating such an amount of EGR gas in the cylinder that satisfies the sub injection so as to be held in the cylinder. Accordingly, even if the next cycle is a stratified-charge combustion, the temperature in the cylinder is maintained at a high level, so that carburetion of fuel by a main injection 1 on compression stroke is accelerated. Also, the maximum combustion temperature is lowered by the quantity of heat of an inert gas contained in the cylinder gas and the NOx can be reduced sufficiently.  It is preferred to control the valve overlap period of intake/exhaust valves with a variable valve timing mechanism.

IPC: H04B1/04
Filed: 1985-03-25
Abstract: PURPOSE:To reduce the average power consumption of a remote control transmitter to make the life of the battery used by the transmitter longer, by separating the circuits of the transmission controlling section of the transmitter into high-power circuits and low-power circuits and providing a power supply circuit which directly supplies electricity to the low-power circuits from the battery and supplies electricity to the high-power circuits by a fixed time. CONSTITUTION:When one of operating switches 31-34 is operated, the remote-control controlling signal RC which controls the equipment corresponding to one of the operating switches 31-34 is outputted from a transmission controlling circuit 20. Simultaneously, the capacitor C0 of a power supply circuit 8 is charged through diodes D1-D4 and a resistance R0. The both-terminal voltages of the capacitor C0 is applied across the power supply terminals of externally fitted circuits, such as external transmitting circuit 21, frequency dividing circuits 22 and 24, etc., and electricity is supplied to the externally fitted circuits during the period when the operating switches are turned on and during the discharging period of the capacitor C0 only. During the above-mentioned period, a projector 25 is driven in accordance with the remote-control controlling signal RC and a prescribed infrared signal is transmitted. In this case, the electricity is supplied to the externally fitted circuits which are high-power circuits consuming relatively large electric power and the circuits are driven to the necessary minimum degree during a fixed period when the operating switches are operated.

Title: Intake air control unit for internal combustion engine
Inventor: KANAMARU MASANOBU
IPC: F02D41/06
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To enhance startability by restraining excessive changes of intake air quantity under the open state of a switch valve at the completion of fully closed control over the switch valve, at a starting process of a multi-cylinder internal combustion engine having an electronic control switch valve. SOLUTION: In an internal combustion engine, having an electronic control switch valve in an intake duct, the opening of the switch valve is controlled at a starting process of the engine so as to attain a first opening which is an approximately fully closed state. Then air consumption consumed in and after cranking of the engine with the first opening for the switch valve is determined. Based on the determined value of the air consumption, a consumption ratio of an intake system air quantity existing within the intake duct from downstream of the switch valve up to intake valves of respective cylinders is determined. By multiplying the consumption ratio and an intake air quantity required to intake after the completion of the fully closed control, air quantity at the transition to an open valve state is determined.  Comparing the second opening and the first opening of the switch valve through which the air quantity under transition passes, the opening of the switch valve is controlled so as to attain a greater opening. As a result, excessive changes of intake air quantity are restrained, while the switch valve is in the open state at the starting process of the engine, and thus an engine startability is improved.
