Title: Pulse generating circuit
Inventor: KURODA HIROYO
IPC: H03K3/0231
Filed: 1989-02-16
Abstract: PURPOSE:To make an output pulse width constant by connecting an output pulse end signal of a monostable multivibrator to a charging system of a capacitor via a feedback system. CONSTITUTION:When a trigger signal enters an input terminal 7, a MOS transistor(TR) 3 is turned on with a logic circuit 8-2 and an output level at an output terminal 6 changes from 'L' to 'H' simultaneously. A capacitor 2 is discharged attended with the turning-on of the TR 3, and when the level decreases up to a threshold voltage of a buffer 5, the TR 3 is burned off and the capacitor 2 is gradually charged via a resistor 1. When the level reaches the threshold voltage of the buffer 5, the output voltage at the terminal 6 changes from 'H' to 'L'. The change is detected by a logic circuit 8-1 and a TR 3' is turned on. Thus, the capacitor 2 is charged momentarily up to a VDD. Thus, the pulse width of the output pulse 2 is always made constant independently of the timing of an input trigger.

Filed: 1985-02-25
Abstract: PURPOSE:To drop the pressure of a discharging diode without adding newly a part by connecting a diode in the reverse bias direction across the base and the emitter of one transistor comprising a current mirror circuit. CONSTITUTION:A trigger voltage is impressed on the input of a pulse output circuit, and transistors TRs Q1-Q6 comprising a constant current source charge a capacitor C. During the charging a pulse is outputted, and the charge of the capacitor C is discharged through the diode D when a voltage is not impressed. The diode D is connected in the reverse bias direction across the base and the emitter of one transistor TR Q2 of the current mirror circuit comprising some part of the constant current source of the output circuit. A current decided by a resistance R1 at the time of inputting and impressing is reflected by the mirror circuit to discharge it to the capacitor C, and its charge is discharged to a power source line by the diode D connected to the TR Q2. Then voltages at both ends of the diode D are limited to voltage drops in the TRs Q1 and Q2, and accordingly the pressure of the discharging diode is reduced.

Title: Magnetic force type shape measurement
Inventor: KUNIEDA MASANORI
IPC: G01B7/28
Filed: 1984-02-29
Abstract: PURPOSE:To enable continuous detection of a shape with a non-contact type simple and small sensor by bringing a magnet close to the surface to be measured comprising a ferromagnetic substance to measure the displacement of the magnet when it is attracted in the direction of normal of the surface being measured. CONSTITUTION:A magnet 2 which is mounted on a support 3 is brought closer to a surface 11 to be measured. When the surface 11 being measured is made of only a ferromagnetic substance, a stress working on the discontinuous boundary plane between different magnetic materials has only the component vertical to the boundary plane and turns to the one smaller in the magnetic permeability from the one larger therein and hence, the magnet 2 is invariably attracted in the direction of normal of the surface 11 being measured. Then, by measuring the displacement of the magnet 2 with a displacement measuring device 4 employing a 3-component gauge or the like, the distance from and inclination of a curved surface are detected simultaneously with only one fine sensor structure. This enables the detection of the normal direction of the curved surface of the ferromagnetic substance, simultaneous detection of the distance from and inclination of the curved surface, the measurement of direction of inclination of any surface, angular parts and corners and furthermore, the detection of the center and direction of a hole.
