Title: Stabilizing device for ac rectangular wave voltage
Inventor: IWANAMI YOSHIKAZU
IPC: G05F1/445
Filed: 1987-11-20
Abstract: PURPOSE:To improve the stability of the AC rectangular wave voltage by applying the negative feedback control to a serial control transistor TR set between the input and output TRs based on the detecting result of the output voltage. CONSTITUTION:The stable AC rectangular waves supplied to the input terminals 1 and 2 of an input transformer 3 are applied to an output transformer 13 via diodes 5 and 6 and a serial control TR 4. The diodes 5 and 6 are repetitively turned on and off in each half cycle of the AC rectangular waveform to always bias the TR 4 in the fixed direction. The transformer 13 rectifies the AC rectangular wave voltage of an output voltage detecting winding via the diodes 11 and 12 and smoothes the rectified voltage via a capacitor 10 to acquire the DC voltage. This DC voltage is compared with the reference voltage 9 via an error amplifier 8 and amplified for control of the collector-emitter voltage of the TR 4. Thus the AC rectangular wave voltage produced between output terminals 14 and 15 of the transformer 13 is stabilized.

Title: Coordinate input device
Inventor: KIMURA KIYOSHI
IPC: G06F3/0488
Filed: 1985-12-26
Abstract: PURPOSE:To set a switching element at the shortest distance from an input plane and to eliminate the effect of a magnetic field produced at the lead wire part of the end part of a loop, by providing a switching element at the end part of each loop. CONSTITUTION:A transistor TR4a is connected to the end part of each loop of a conductor Ln among those loops set in parallel with each other in the direction X where the detection signals of the positions indicated by a coordinate indicating tool are outputted. Then a conductor Lx is scanned. The same constitution is applied also to the loop conductor in the direction Y which is orthogonal to the conductor Lx. Thus the switching element can be set at the shortest distance from an input plane since the whole part of the loop conductor is not connected to a pair of switch parts for scan. Thus it is possible to eliminate the effect of a magnetic field produced at the lead wire part of the conductor set at the end part of the loop and the accurate coordinate information can be inputted.

Abstract: PURPOSE:To realize a chip carrier mounted with a compound semiconductor IC of excellent high-frequency and speed features by a method wherein a GaAs MESFET IC chip is installed on a silicon substrate and then various pads, circuits for converting input and output levels, etc., are formed. CONSTITUTION:A pad of an IC chip 13 installed roughly at the middle of a chip carrier is connected by a bonding wire 14 with a pad of a chip carrier located very near to said pad.
