Title: Coordinate detector
Inventor: YOSHIKAWA KAZUO
IPC: G06F3/045
Filed: 1985-08-10
Abstract: PURPOSE:To detect the coordinates with reduced effect of noises by setting the oscillation frequency of a CR oscillator for detection of coordinates in relation to the induction noises produced from a coordinate display device after providing an additional capacity. CONSTITUTION:When a touch finger is given to a touch panel 12 of a resistance film containing a transparent electrode of ITO, the change of impedance due to the capacity ratio set up to the touch position is detected by a CR oscillator 16 of a capacity measuring part 15. Then, the oscillation output of a frequency corresponding to the coordinate position is produced. The oscillation frequency of the oscillator 16 is set at the medium level between the n-degree and (n+1)-degree higher harmonic waves of the induction noise given from a display device by an additional capacity 23 when no connection of impedance is given to the resistance film. Thus, the oscillation frequency of the oscillator 16 corresponding to the coordinate value is kept within the frequencies between the n-degree and (n+1)-degree higher harmonic waves excluding these waves. This attains the detection of coordinates with reduced effect of noises.

IPC: B27B33/08
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a rotating edge capable of roughening easily its section when a material to be cut is cut. SOLUTION: A plurality of cutting edges 11 (11a-11c) are provided at specific pitches along a peripheral direction in an outer peripheral part of a basic substance 10 which is formed in a disk shape and rotated around an axis. Partial cutting edges 11b, 11c among a plurality of cutting edges are arranged more inside in a radial direction of the basic substance 10 than the other cutting edge 11a, and formed so as to be projected on both outsides of a thickness direction of the basis substance 10 than the other cutting edge 11a.

Title: Transmission/reception antenna switching device
Inventor: HARAGUCHI YUJI
IPC: H04B1/50
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To reduce the degradation of reception sensitivity, due to switch and to simplify circuit configuration by switching transmission and reception by directly connecting a transmission/reception antenna to a reception circuit and providing the switch between a transmission circuit and the transmission/ reception antenna. SOLUTION: A reception circuit 3 and a transmission/reception antenna 1 are directly connected to each other. When a switch 5 is turned off, the state of reception is obtained, but when the switch is turned on, the state of transmission is obtained. In such a transmission state, the reception circuit 3 and a transmission circuit 4 are connected in parallel, but at the time of transmission, it is not necessary to supply power to the reception circuit 3, so that the reception circuit 3 can be made into high impedance. Therefore, transmission can be performed from the transmission/reception antenna 1, without the flow of transmission output into the reception circuit 3.  Thus, since the reception circuit 3 and the transmission/reception antenna 1 are directly connected, the loss on the side of reception due to by the switch 5 is reduced and further, circuit configuration can be simplified.
