Title: Apparatus and method for driving light emitting element
Inventor: KAMEYAMA SHOGO
IPC: H05B44/00
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To ensure voltage required in driving light emitting elements and reduce a voltage loss, a size of a main body and manufacturing cost. SOLUTION: A voltage Vdd outputted from a battery 12 loaded on a car is selectively applied to data electrodes 8b when an organic EL panel 8 is driven, and a voltage Vss outputted from a secondary power circuit 14 is selectively applied to scan electrodes 8a. The secondary power circuit 14 includes a pole reversing type of converter 13 and outputs the voltage Vss having polarity (negative) opposing to that of voltage Vdd outputted form the battery. Therefore, when the organic EL display panel 8 is driven, a relatively large potential difference is applied selectively between a pair of electrodes of an organic EL element 1, wherein the potential difference is the sum of the absolute value of voltage Vdd outputted from the battery 12 to the absolute value of voltage Vss outputted from the secondary power circuit 14.

Title: Socket device for fluorescent lamp
Inventor: OKAMURA KENJI
IPC: H01R33/08
Filed: 1987-12-29
Abstract: PURPOSE:To reduce the number of parts and simplify the mounting process by constituting one shoulder part of a socket main body out of a mounting spring to press down elastically from above. CONSTITUTION:When a fluorescent lamp 2 is inserted in the plug 5 for fluorescent lamp resisting the elasticity of a socket main body, a base pin 6 comes to naturally contact with a contacting part 7. Also, since the fluorescent lamp 2 end the plug 5 for the fluorescent lamp contact each other closely, the gap between both comes to bear air-tightness, so the moisture never enter from here and similarly the moisture never enter from between a lead hole 9 and a lead wire 8 inserted into here, either. As a result, by inserting the fluorescent lamp 2 into the plug 5 for fluorescent lamp of the socket main body, the inside of the socket main body comes to be provided with a water preventive function. Hereby, the number of used parts required for installing an apparatus rain body can be reduced and further, the mounting process to the apparatus main body can be simplified.

Title: Fault simulation method
Inventor: MOTOHARA AKIRA
IPC: G06F19/00
Filed: 1987-12-29
Abstract: PURPOSE:To attain considerably high speed fault simulation by processing plural and different simulation models generated with respect to one design data in parallel by means of hierarchical fault simulation. CONSTITUTION:A simulation model generation means 1 fetches design data, hierarchy-develops a part of hierarchical data, and generates plural models for fault simulation before it begins fault simulation. Plural fault simulation means 2 fault-simulate the simulation models which are respectively given. The parts which are assumed to be fault are developed in the lowest-order hierarchy and the parts except for said parts are remained as the function blocks of the high-order hierarchy. Consequently, the number of the elements of one simulation model can considerably be reduced, and respectively generated simulation models can be processed in parallel. Thus, high speed fault simulation is attained.

Title: Ink jet recorder
Inventor: OKITA KENJI
IPC: B41J2/01
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder in which the number of types of recordable image can be increased by making the apparent nozzle pitch alterable. SOLUTION: The ink jet recorder comprises a carriage 3 reciprocating in the main scanning direction, and a plurality of recording heads 2 having a nozzle array 13 including a plurality of nozzle openings 14 for ejecting ink drop wherein the carriage 3 is provided with a plurality of holes 10 for securing a recording head 2 removably. Since a switching can be made between a state where the nozzle openings 14 are arranged on a line in the direction perpendicular to the nozzle array 13 and a state where the nozzle openings 14 are arranged while being shifted in the direction of the nozzle array 13, between the nozzle array 13 of any one recording head 2 and other recording head 2, high resolution printing can be effected by shifting the nozzle openings 14 to decrease the apparent nozzle pitch.  When such printing is not required, normal printing can be effected by arranging the nozzle openings 14 on a line and the number of types of recordable image can be increased by altering the apparent nozzle pitch.

Title: Variable valve-timing control device of internal combustion engine
Inventor: INOUE MASAOMI
IPC: F01L1/46
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of the variable valve-timing control by reducing the rate of occurrence of failed unlocking operation in a locking mechanism of a variable valve-timing device. SOLUTION: Unlocking control is conducted for a locking mechanism of a variable valve timing device, followed by a determination as to whether unlocking is generated correctly, and if it is a no, the failure relief control for a hydraulic control valve is conducted, and the motions to reciprocate the valve element of the control valve in prescribed strokes are repeated (steps 101-103). Thereby the control valve can be restituted to the normally operable condition by the failure relief control in the case the failed operation is of temporary type, for example originating from foreign matters biting into the control valve. Determination is made whether the control valve is in normal operation until the failure relief control is finished (step 104), and if the valve operation is normal, the unlocking control is re-conducted (step 106).  If at this time, the locking mechanism is normal, unlocking can be generated by re- conducting the unlocking control.

Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a spark plug hardly damaging a central electrode during the positioning of a preliminary bend spacer and capable of giving a relatively large radius of curvature to the bent section of a ground electrode. SOLUTION: A preliminary bend spacer 42 is moved in the lateral direction from a retreat position PA2 set aside from the arranging direction of a central electrode W1 and a ground electrode W2 to a bend reception position PA1 facing the tip face of the central electrode W1 for positioning in preliminary bending.

The position of the bending die face 42a of the preliminary bend spacer 42 can be located near the base end side of the ground electrode W2, thus the radius start section of the ground electrode W2 can be moved near the electrode base end. The radius of the bent section of the ground electrode W2 can be made large, and breakage caused by stress concentration hardly occurs even when vibration is applied to a plug in use.
