Title: Current controlled oscillator
Inventor: HITOMI JUICHI
IPC: H03K3/282
Filed: 1985-09-25
Abstract: PURPOSE:To improve the temperature drift of a current controlled oscillator possible for low voltage operation without almost increasing number of components by setting the current density of the 5th transistor (TR) differently from that of the 3rd and 4th TRs. CONSTITUTION:TRs 1-7, resistors 8, 9 and a capacitor 12 are provided. In this case, in selecting the emitter area of the TR 5 as n-time of the emitter area of the TR 3 or TR 4, the current density of the TR 5 differs from that of the TR 3 or TR 4. That is, in selecting a terminal voltage as Vc and selecting a voltage between that at an output terminal 16 and a power voltage Vcc as V0, then the relation of Vc=V0 is attained by selecting the (n) properly to make the temperature drift of the voltage Vc zero thereby compensating the temperature drift of the oscillating frequency f0.

IPC: G06F11/32
Filed: 1988-08-25
Abstract: PURPOSE:To accurately confirm an error event through confirmation of the internal working state near an executing instruction designated by a program executing address set externally by producing a trigger pulse when the coincidence is obtained between the program executing address and the executing address of a program counter. CONSTITUTION:An address setting circuit 1 sets externally the executing address of a process program which may possibly includes an occurred error. Then a program counter 2 contained in a computer application device is used together with an address coincidence deciding circuit 3 which decides the coincidence between the address set externally by the circuit 1 and the address to be executed by the counter 2, and a trigger pulse generating circuit 4 which produces a trigger pulse when the coincidence is obtained between a set address and an executing address via the circuit 3. Then an operator confirms and inputs the trigger pulse to a display device 5 like an oscilloscope, a logic analyzer, etc., and confirms the error states before and after the trigger pulse. Thus it is possible to confirm the internal state of an error origin.

Title: Feed screw device and scale recording method for screw shaft thereof
Inventor: IZAWA MINORU
IPC: F16H25/24
Filed: 1988-08-26
Abstract: PURPOSE:To obviate a sensor for detecting a nut position and a motion start or terminal point and ensure a compact design and precise position control by recording a scale, audio or image information and the like on the external surface of a screw shaft along a lead groove and providing a nut with an information read means. CONSTITUTION:When the rotary shaft 15 of a motor 11 turns according to an instruction from CPU 9, the rotary motion thereof is reduced and transmitted to a screw shaft 2 via a power transmission device 12. In addition, a nut 3 coupled to a lead groove 2a due to the rotation of the shaft 2 moves in an A or B direction by a distance calculated with the pitch P of the groove 2a and a rotational angle theta of the groove 2a in accordance with the rotational direction of the shaft 2. Also, a screw feed device is operated to move the nut 3 on the rotation of the shaft 2 and more highly efficient feed control is thereby made. Furthermore, the read means 4 of the nut 3 moves together with the nut 3 and, therefore, a detecting plane 4a reads a scale 6 on the external surface 2d of the shaft 2 and sends a corresponding signal. In this case, the signal controls the motion of the motor 11 on the basis of arithmetic processing by CPU 9 and the position of a moving body is thereby controlled for the nut 3 and the failure of fixture.
