Title: Component-mounting method
Inventor: KAWASE TAKEYUKI
IPC: H05K13/04
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To increase the moving amount of an X-Y table by performing the movement of the X-Y table to a position indicated in the next step of a mounting program when mounting operation is not performed by using a period which is capable of the X-Y table movement wherein mounting is not performed and the next period cable of X-Y table movement. SOLUTION: When mounting is not performed, the operation of an X-Y table is unnecessary during a mounting period, so that the mounting operation of the X-Y table in the next step of a mounting program is performed. First, the amount L1 that the X-Y table can move in the period capable of movement of the X-Y table is calculated from the operation speed of a rotating table and that of the X-Y table. Secondly, the amount L1 is compared with the amount L of movement of the mounting program, and the contents of L are transferred to L2 in the case of L<=L1. Movement of the amount L2 is performed during the period which is capable of X-Y table movement, and processing is ended. As a result, the moving amount of the X-Y table can be increased.

IPC: F02D11/02
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a governor which may be automatically assembled, and which may prevent a first spring of a governor spring assembly from acting upon a governor lever.

Title: Surge absorption element
Inventor: SUZUKI YOSHIRO
IPC: H01T1/20
Filed: 1988-08-05
Abstract: PURPOSE:To be small-sized while improving a life characteristic by parallel- connecting dielectric layers having a good creeping discharge characteristic to a discharge gap and voltage non-linear resistor for being sealed in an airtight container. CONSTITUTION:Dielectric layers 5 having a good creeping discharge characteristic are connected in parallel to a discharge gap 4 and a voltage non-linear resistor 2 and this is sealed in an airtight container 6 filled with discharge gas. When surge is impressed, a current immediately flows through the voltage non-linear resistor 2 and when a voltage drop corresponding to the product of current value and resistance value of the voltage non-linear resistor 2 exceeds creeping discharge starting voltage between the discharge electrodes, creeping corona discharge is generated. Discharge lag time of creeping discharge is extremely small as compared with air discharge so that translation time of a surge absorption action to surge absorption due to a discharge phenomen is shortened. Thereby, energy load of the voltage non-linear resistor 2 is reduced so that a life characteristic can be improved while being small-sized.
