Title: Vacuum pump
Inventor: ODATE YOSHINOBU
IPC: F04D29/44
Filed: 2001-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum pump capable realizing favorable vibration damping ability even when there is a pressure difference inside and outside a damper. SOLUTION: A damper is formed in an inlet of the vacuum pump. The damper is connected to an outlet provided in a lower part of a vacuum device, and the vacuum pump is suspended from the vacuum device. One end of a coil spring is attached to a bottom of the vacuum pump, and another end of the coil spring is attached to a fixing object below the vacuum pump. In the coil spring, restoring force acts in the direction extending the damper. Since vacuum is formed in an interior of a damper part when the vacuum pump is operated, the damper part is compressed by atmospheric pressure and it tries to contract, but the damper is extended by the restoring force of the coil spring. By this, reduction of an elastic modulus following contraction of the damper can be reduced, and consequently, vibration absorbing ability of the damper can be maintained.

Title: Print controller, print control method, program and storage medium
Inventor: IIIZUMI TOMOO
IPC: B41J5/30
Filed: 2001-04-11
Abstract: PROBLEM TO BE SOLVED: To realize high speed print processing by lessening the load on a CPU generally controlling the print processing. SOLUTION: Assuming that a bit map RAM can store bit map data for two bands, writing processing R1 and R2 of bands having sequential numbers of '1' and '2' are performed, respectively, at timing T1 and T3, and each bit map data thus formed is stored in a bit map RAM. Consequently, the value 103 stored in a register becomes '2'. The count 102 of a counter is initially set at '1' and the stored value 103 does not match the count 102. In this case, writing processing R3 of next band having a sequential number of '3' enters execution waiting state. When image output processing S1 of a band having a sequential number of '1' is ended at timing T12, the count 102 of the counter becomes '2'. Since the count 102 matches the stored value 103, the writing processing R3 under waiting state having a sequential number of '3' can be executed.
