Title: Thermal stress relaxation structure for cylinder head of internal combustion engine
Inventor: FUJII AKIRA
IPC: F02F1/42
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a thermal stress relaxation structure for a cylinder head of an internal combustion engine, capable of enough relaxing thermal stress, and simultaneously sufficiently maintaining the rigidity of the cylinder head. SOLUTION: Since a thermal stress relaxation slit 16 is formed to be gradually shallow except the deepest part 16a, the rigidity of a cylinder head 2 can be maintained and the deterioration of a sealing property between the cylinder head and a cylinder block can also be prevented. Since the part which approximately corresponds to the center of a combustion chamber is formed as the deepest part 16a, thermal stress of the center part of the combustion chamber, which is considered to be especially large thermally expanded, can be relaxed. Further, since the depth of thermal stress relaxation slit 16 is gradually changed, the stress concentration at the top 16b is also suppressed. Besides, the thermal stress relaxation slit 16 is not connected to head bolt holes 18, 20, cooling water paths 22, 24, etc. Thus, adverse effects to the maintenance of the rigidity of the cylinder head 2 can be prevented.

Title: Electromagnetically driven valve controller for internal combustion engine
Inventor: OGAWA MASARU
IPC: F01L9/04
Filed: 1994-12-16
Abstract: PURPOSE: To prevent an intake valve and/or an exhaust valve from being brought in contact with a piston, by driving the intake valve and/or the exhaust valve on its closing side when a starting signal is detected, and allowing operation of starter means to start engine operation when the time elapsed from a starting signal detecting period exceeds predetermined prohibition time. CONSTITUTION: An intake valve 10 has a valve driving part 1 including an armature 4, and is mounted in the upper part of a combustion chamber so as to open/close the intake opening 8 of the combustion chamber. The closing side solenoid 5a of the valve driving part 1 or the opening side solenoid 6a thereof is energized so that a valve body 2 is moved between a fully closing position and a fully opening position. In this case, when an ignition switch is switched ON, a delay count value is set according to coil temperatures of battery voltage and an electromagnetically driving solenoid so as to output the valve closing command signal of the intake valve 10. Next, the delay count value is decreased from that point of time, and when the delay count value reaches 0, engine operation is allowed to lee started.

IPC: H02J13/00
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To lighten and downsize a switch for high-tension distribution line, and heighten lightning surge resistance. SOLUTION: The moving electrode 10 of a main electrode disposed between the power source side 8 and the load side 9 of a high-tension distribution line is opening and closing operated by the plunger 13 of an operating magnet 6.

Inventor: MOCHIZUKI TETSUYA
IPC: F04C29/12
Filed: 1990-11-30
Abstract: PURPOSE:To attract worn powder contained in delivery gas to a magnet and prevent the generation of sludge, by introducing refrigerant gas in a sealing vessel to a delivery tube provided on the outside of the sealing vessel from a delivery hole in a compression element, and attaching a magnet on the inner wall of the sealing vessel facing to the delivery hole. CONSTITUTION:Refrigerant gas containing worn powder delivered from a delivery hole 13 of a compression element 2 is blown on the inner wall of a sealing vessel 1 facing to the hole 13. A magnet 10 is attached to a position facing to the delivery hole 13 on the inner wall of the sealing vessel 1, hence the worn powder is attracted to the magnet 10, so the amount of worn powder circulated in circuits through the delivery tube 6 can be minimized to suppress the generation of sludge. And the generation of malfunction or locking of sliding portions of the compressor due to the circulation of worn powder in the circuits can be prevented.

Abstract: PURPOSE:To improve control accuracy by controlling an automatic transmission based on the detected value of a present controlled quantity in the unstable condition of a throttle, or on the forecast of the controlled quantity after a very short time in the stable condition. CONSTITUTION:In an electronic control unit 120, the rate of throttle opening is calculated from the signal of a throttle opening sensor 161, and the unstable condition or stable condition of a throttle is judged.

Filed: 1994-12-22
Abstract: PURPOSE: To match the direction to move the pointing input device with the moving direction of a cursor obtained by the turn of the pointing input device even when the pointing input device is turned on an operating plane. CONSTITUTION: This device is incorporated with two rotary balls 2 and 3 longitudinally. A line segment with which two points of the rotary balls 2 and 3 are connected to each other is defined as the reference axis of the input device. The position of the reference axis at the time of first mounting the input device on the operating plane is defined as the reference axis of the operating plane. The respective rotary balls 2 and 3 decompose the moving amount of the mouse into X and Y directions and detect them.  From the difference of those detected moving amounts, a correction calculating circuit part 20 calculates the turning amount of the reference axis at the input device corresponding to the reference axis of the operating plane to mount the input device, and based on the turning amount and the detected moving amounts, the moving amount corresponding to the reference axis of the input device is corrected into the moving amount corresponding to the virtual reference axis of the operating plane.
