Title: Ultrasonic coordinate input device
Inventor: ISHIKAWA HIROSHI
IPC: G06F3/043
Filed: 1993-05-12
Abstract: PURPOSE:To prevent the decline of the efficiency of ultrasonic wave propagation and to accurately detect coordinates by sticking a sheet-like piezoelectric body on a substrate with a first electrode held between and impressing a voltage for generating ultrasonic waves between an electrode on the tip part of an operator and the first electrode. CONSTITUTION:A film-like piezoelectric body 400 on which the first electrode 200 is formed on one surface of the substrate 10 is formed and the first electrode 200 is arranged between the film-like piezoelectric body 400 and the substrate 10 and grounded. The piezoelectric bodies 21 and 22 for reception use are arranged at the corners of the substrate 10. When an input pen 300 provided with the electrode 311 on the tip part 310 is brought in contact with the surface of the sheet-like piezoelectric body 400, a voltage pulse is sent from a pulse transmission circuit 32 and the part of the sheet-like piezoelectric body 400 brought in contact with the input pen 300 vibrates. The ultrasonic waves are symmetrically propagated from the vibrated part, received by the piezoelectric bodies 21 and 22 for use of reception located on the corners of the substrate 10 and converted to electric signals. In a coordinate detection part 24, a distance is obtained by multiplying propagation time by a sound speed and the coordinates of a position brought in contact with the input pen 300 are calculated.

Title: High frequency hybrid integrated circuit
Inventor: DEGUCHI KAZUHIDE
IPC: H03F3/195
Filed: 1988-05-07
Abstract: PURPOSE:To eliminate the need for earthing of the circuit in terms of high frequency and to attain broad band by providing balanced type input terminals and balanced type output terminals in pairs through the balanced configuration. CONSTITUTION:High frequency transistors(TR) are configurated as push-pull to constitute the circuit to be a balanced type circuit. Thus, the entire hybrid integrated circuit is formed to be balanced type in terms of high frequency and no earthing is required. However, it is required for balance-unbalance conversion by external balance-unbalance conversion circuit 6a, 6b. Since the matching circuit constituted to be of balanced type has a lower Q of the circuit in comparison with the unbalanced matching circuit, broad band configuration is attained.
