Abstract: PURPOSE:To attain stable detection and to improve the reliability, by setting stepwise a resistance of a pull-up resistor connected to a detection circuit via a detection wire basing on the relation between the resistance value of the detection wire and the detected position. CONSTITUTION:In pressing a soft upper member 1 with a finger 9 and a pen, the detection wire 2 formed on said upper member 1 contacts the detection wire 4 formed on a lower member 3, the detection wire 2 is driven with a drive section 5, and a potential change obtained from the relation between the resistance value and the detecting position of the pull-up resistor 8, and the detection wires 2, 4 is produced on an input wire of a detection circuit 6 corresponding to input positions (j, i). The detection circuit 6 can detect the input positions (j, i) from the position of drive element of the drive section 5 and the input wire of the circuit 6. Stable detection over the entire detecting position is done by setting stepwise the resistance value Rj of the pull-up resistor 8 corresponding to the circuit 6 from the relation of the resistance value and the detection position between the detection wires 2, 4.

Title: Valve opening detector
Inventor: FUCHIWAKI KOICHIRO
IPC: F16K37/00
Filed: 1987-03-12
Abstract: PURPOSE:To prevent chattering of valve by regulating pulse interval of optical pulse signals corresponding to motion of a member which is interlocked with open/close motion of the valve to block the light. CONSTITUTION:An optical pulse signal transmitted from a projector 2 is received by a receiver 3 without blocked by a blocking member 1. The received signal is converted into an electrical pulse signal by a light receiving device 19 and fed to an integrator 6 where it is converted into a D.C. level output signal. When the valve starts to open, the optical pulse signal is blocked by the light blocking member 1 and a signal indicating open/valve state is fed to an output circuit 8 and a pulse modulation command circuit 17. Consequently, a signal for commanding to reduce the number of pulses of the optical pulse signal per unit time is fed from the circuit 17 to a transmitter 18'. When the valve starts to close, signal for commanding reduction of the number of pulses is not provided. Consequently, chattering can be prevented.

Title: Bootstrap circuit
Inventor: HIGAKE MASAKATSU
IPC: H03K19/094
Filed: 1985-03-22
Abstract: PURPOSE:To obtain bootstrap effect without any delay by connecting at least two capacitors and a switching circuit which is connected to those capacitors in parallel and charges those capacitors with a source voltage respectively. CONSTITUTION:When an input voltage is at a level L, a bootstrap capacitor C1 is charged through the route of a transistor (TR) Q1, the capacitor C1, and a TR Q5, and a capacitor C2 is charged through the route of a TR Q2 and the capacitor C2 in parallel. When the input voltage IN rises to a high level H at this time, the capacitors C1 and C2 are connected in series through a TR Q3, the capacitor C1, a TR Q4, and the capacitor C2. Consequently, the voltage of a node N2 as the gate of the output TR Q7 of an E/E type driver is twice as high as the capacitor voltage when the capacitors are connected in parallel and higher than a source voltage. Therefore, a voltage equal to the source voltage Vcc is obtained as an output voltage OUT.
