Title: Muting control circuit

IPC: H04B1/10
Filed: 1977-12-14
Abstract: PURPOSE:To mute the unpleasant pop noise which is generated when switching on and off the power supply by changing the making/breaking signal of the power supply into the muting control signal through the logical sum circuit. CONSTITUTION:With closure of power switch 27 of the muting control circuit, base potential VB31 of transistor Tr11 rises simultaneously with 30a of power voltage 30 like 31a but VB32 of Tr14 rises with a delay equivalent to the charge time of capacitor C18 like 32a. And Tr11 is turned on with Tr14 turned off respectively by the theory of the differential amplifier, and the double current flows to the collector of Tr11. Thus, the collector potential lowers like 34a, and the collector potential of Tr14 becomes identical to the power voltage like 33a. Accordingly, VB of Tr20 becomes over threshold voltage Vth, and thus Tr24 is turned on with output terminal 25 potential turned to low level 35a. When charging of C18 is over with identical VB obtained between Tr11 and 14, the circuit becomes stable with output 25 potential turned to high level 35.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet apparatus which can vary a frequency for driving nozzles and the number of simultaneously driven nozzles according to a printing rate so as to restrict power consumption of a driver circuit and to control an irregularity in speed for jetting ink drops in an ink jet recording apparatus. SOLUTION: Printing data is monitored by a host of a printing head, and a speed for moving a printing head is changed according to a printing rate thereby making constant a frequency for driving nozzles, so that a maximum consumed power of a nozzle drive circuit is restricted. Banding printing is carried out according to the printing rate, thereby restricting the number of simultaneously driven nozzles. A variation in fluid vibration in an ink chamber is thus restricted, so that an irregularity in speed for jetting ink drops is restricted.

IPC: B24B41/06
Filed: 1989-06-13
Abstract: PURPOSE:To apply cylindrical grinding concentrically accurately to the internal and external diameters of an optical connector part by holding a workpiece in the vicinity of its diameter with disks and rotating the workpiece. CONSTITUTION:Since rotation of a spindle 20 is stopped, all the parts in a spindle surface plate 19 are placed in a stationary condition. Under this condition, because a main unit 6 is pulled by a tensile spring 16 toward a balancer 8, when disks 1-a, 1-b are sufficiently mounted to a spindle center 22 so that a workpiece 21 can be easily inserted, the workpiece is held by a tail center paired with both the centers. Then the spindle 20 is started to perform throwup- rotation in the counterclockwise direction. Next, when the rotation reaches a certain rotary speed, the main unit 6 is moved by its own centrifugal force toward the periphery against force of the tensile spring 16, and following this action, the disks 1-a, 1-b hold the workpiece 21 rotated in the counterclockwise direction. Next a grindstone approaches from the right to grind the workpiece 21 in the predetermined dimension.
