Title: Two-cycle internal combustion engine
Inventor: TANAHASHI TOSHIO
IPC: F02B25/24
Filed: 1987-01-13
Abstract: PURPOSE:To improve combustibility by letting a part of exhaust gas discharged from an exhaust port flow in the state of a swirl into a combustion chamber in an exhaust stroke, and disposing a ceramic layer at least on the wall surface of the exhaust port. CONSTITUTION:Two fresh air ports 24 and two exhaust ports 26 are formed on a cylinder head 14 and opened and closed by fresh air valves 20 and exhaust valves 22 which are driven in synchronization with a crank angle. In order to let a part of exhaust gas discharged from a combustion chamber again flow into a combustion chamber while a swirl is generated in an exhaust stroke at the time of low load operation of an engine, masks 26a partially surrounding opening portions of the exhaust ports 26 are formed on the wall surface of the cylinder head 14. In tis arrangement, stratiflcation between fresh air and the residual exhaust is promoted. Further ceramic layers 66, 68 are formed on the wall surface of the exhaust ports 26 and the inner wall surface of the cylinder head 14, thereby preventing lowering of temperature of exhaust gas again flowing into the combustion chamber 18.

IPC: H02P8/12
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To eliminate current irregularity and stabilize balance of a phase current by performing constant current control, by chopping only one switching element which is switched to on-state in the upper stage or the lower stage, out of a pair of upper and lower switching element groups for bipolar drive. SOLUTION: When arm chopping drive is performed with 4-phase excitation by bipolar pentagon drive, switching element groups of a drive circuit which are switched to on-state are two on the upper stage side (power source side) and one on the lower stage side (ground side), or one on the upper stage side and two on the lower stage side. One where the switching element out of the upper stage and the lower stage switched to on-state is one is selected, and constant current control is performed by chopping. The chopping system of an upper arm (power source side arm) and a lower arm (ground side arm) performs chopping at a point P1 where a current flows into windings and branches and at a point P2 where currents flowing through the windings gather.

Abstract: PURPOSE:To make it possible to simply confirm an abnormal system by amplifying a drive control signal for driving an electrohydraulic convertor so as to feed the same as a drive signal and by ascertaining whether the drive current is appropriate or not in accordance with a load detection signal from a load current detector. CONSTITUTION:A computer control device 4 sets a variable (i) so as to be i=a, and ascertains whether a drive control signal DCSa for a solenoid valve 8a corresponding to i=a, is delivered or not. Further, if it is delivered, it is ascertained whether the drive control signal DSa runs or not in view of a detection signal from a load current detector 9a. If it runs and the value of the current is an allowable value, the variable is updated so as to be i=b, and then diagnosis for the next solenoid valve 8b is carried out. Futher, if it exceeds the allowable value, meaning that an abnormality occurs in a signal path for the solenoid valve 8a. Meanwhile, if no signal DSa runs even through the signal DCS runs, a switch is turned off to cut off signals DSa to DSn for all solenoid valves 8a to 8n. Further, if no DSCa is issued but the signal DSa runs, the signal DSa is cut off.

Title: System for controlling air conditioner
Inventor: HAYASHIDA TATSUNAO
IPC: F24F11/02
Filed: 1986-01-14
Abstract: PURPOSE:To improve the reliability in data transmission of the titled system by shifting the transmission side of the system into an inspection mode when a confirmation signal is not obtained even if transmission is carried out for a predetermined number of times, and shifting the receiving side to a transmission action mode when the receiving side cannot receive within a predetermined period of time. CONSTITUTION:When a control data transmission side unit A performs a data transmission, it transmits the same data twice. A transmission side unit B checks the coincidence of data transmitted twice. When the data are coincident with each other, a confirmation signal is transmitted. The reception control is executed by external interruption or the like. The confir mation signal flag F0 is discriminated, and when F0=0, receiving processing is carried out. When it is discriminated that F0=1, a confirmation signal receiving mode is assumed. When F0 is reset to '0' and when the signal being received is a confirmation signal for receiving the transmission of a self unit, presence or absence of the confirmation signal is discriminated. When there is the confirmation signal, the number (n) of times of transmission error is cleared to '0', and a transmission time counted value t1 is cleared, and the reception control is finished. When it is discriminated that confirmation signal is absent, the number (n) of times of transmission error is set to +1. In a case where (n) is equal to or more than a predeter mined number T of times, an inspection mode is assumed. When (n) is smaller than the predetermined number N, the transmission data is set and the transmission flag F1 is set to '1' and a preparation for the transmission for the second time is started.

Abstract: PURPOSE:To improve the dimensional accuracy in the longitudinal direction of a material by controlling automatically the speeds each stand and a mandrel and keeping a tension and a compressive force burdened on a material between roll stands at the prescribed values by adjusting said speeds in the next material. CONSTITUTION:Rolling by each stand and a mandrel is started by lowering the speeds of each stand and mandrel at the fixed rates with respect to the previously set speeds of them. Under said low speed running, the change of an electric current of a stand located at the front stage of an optional stand of mills, formed into a continuous mill line, which is in a state before or after biting a material, is detected.

Successively, the speeds of each stand and the mandrel are simultaneously accelerated and are returned to the speeds set in the beginning. In this way, a tensionless or fixed tension and a compressive force can be set easily.
