Title: Incident edge detection device
Inventor: STEVEN D DOROOBINGU
IPC: H03K5/1252
Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a probe for logic analyzer to detect an incident edge on a transmission line path terminated on a wave source. SOLUTION: This device is provided with a comparator 3004 detecting a rising edge of an input signal and a comparator 3002 detecting a trailing edge. Each comparator 3004, 3002 detects the transition using different threshold voltages, respectively. Outputs of these comparators are multiplexed on clock inputs of a flip flop 3008. Inversion output of the flip flop is delayed by a delay element 3010 for a predetermined time and is input in data input of the flip flop. Moreover, an output of the delay element is connected with a selection input of a multiplexer 3006 to control the multiplex operation. Threshold voltages of two comparators 3004, 3002 are selected in such a way that they come to the center of an incident edge of a distorted signal on a transmission line path.  Time delay is selected in such a manner that it is longer than a difference in time between the arrival of an incident wave and the arrival of a first reflection wave.

Title: Trigonometric function arithmetic circuit
Inventor: TOMARU KENYA
IPC: H04L27/00
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To realize a gain correction coefficient calculating circuit without using a square root calculating circuit and a reciprocal number calculating circuit and to constitute calculating circuit of sinθ and cosθ capable of calculating a sine value and a cosine value with equivalent accuracy as in the conventional one. SOLUTION: Taylor development of a gain correction coefficient calculation formula is performed and the gain correction coefficient is calculated by using an approximate expression of the development expression. In a trigonometric function arithmetic circuit to calculate the values of sinθ, cosθ by the approximate expression of addition theorem, a correction circuit is required to correct an error of amplitude to be generated by approximation. A gain correction coefficient to be used in the correction circuit is calculated by the approximate expression of a coefficient calculation formula. Thus, circuit scale of calculation circuits of sinθ, cosθ are reduced since structure of the gain correction coefficient calculating circuit is simplified.

IPC: B41J2/18
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent wiped ink drops and the like from scattering and staining a surrounding part because a leading end of a cleaning blade is instantaneously oscillated by a repulsive force in consequence of elastic deformation when the cleaning blade separates from a recording head after rubbing against an ink discharge face of the recording head. SOLUTION: A cleaning member 1 is formed by integrally forming an ink drop-absorbing member 2 and the cleaning blade 3 in a layer in a move direction of the recording head 63. Moreover, a pump 13 for sucking ink drops and a waste liquid tank 14 are connected via a tube 12 to the ink drop-absorbing member 2. A cleaning operation is carried out when the recording head reciprocates in front of the cleaning member 1. At a first half of the reciprocation, the ink drop-absorbing member 2 first rubs against the ink discharge face thereby removing ink drops. At a second half of the reciprocation, the cleaning blade 3 rubs against the ink discharge face thereby removing dust, paper dust, etc. Since ink drops adhering to the ink discharge face are first absorbed by the ink drop-absorbing member 2, the ink drops are prevented from scattering.
