Filed: 1984-03-27
Abstract: PURPOSE:To detect automatically a stall state without requiring a manual operation or an inference, and to display a stall address of a microprogram by comparing a micro-address and a comparing address. CONSTITUTION:An address setting circuit 20 inputs an executing address of that time point by an external input signal line 102, informs it to a comparing address circuit 40, and also indicates a start of a time monitor to a timer circuit 30. The address comparing circuit 40 compares a value of a micro-address of a signal line 101, and a comparing address of a signal line 201, and in case they coincide with each other, the coincidence is informed to a counter circuit 50. When the contents of the counter circuit 50 reach a prescribed value, a display is indicated to a displaying circuit 60, a suspension of the operation is indicated to the address setting circuit 20, and also the operation of the timer circuit 30 is suspended. The displaying circuit 60 displays a stall and also displays a stall address.

Title: Rounding arithmetic system
Inventor: ISHIKAWA SUKETAKA
IPC: G06F7/48
Filed: 1983-04-06
Abstract: PURPOSE:To facilitate an easy rounding arithmetic system by adding a data pattern where only the position corresponding to the operand data and its prescribed bit is set at (1) with other positions set at (0). CONSTITUTION:The operand data consists of (m) bits and requires up to (n) bits (m>n) as a result of a rounding operation. In such a case, only (n+1) bits are set at (1) with other bits set at (0) in a data pattern. Such a pattern is added with the operand data. Then the carry-up is produced when the (n+1) bits of the operand data are set at (1). Then the generation of the carry-up is inhibited when said (n+1) bits are set at (0). Thus the rounding operation is facilitated for the operand data of (n+1) bits.

IPC: G01B11/04
Filed: 1995-03-17
Abstract: PURPOSE: To rapidly and simply calibrate a size measuring instrument during operating by measuring the distance from a noncontact type measuring instrument to a calibrating reference plate on a conveying line during the operation. CONSTITUTION: A dummy bar hook 7 is moved down so as to bridge a conveying line, and its hook part 10 is grounded and stopped. As a result, the part 10 is disposed between the line and a laser rangefinder 8. A calibrating reference plate 12 is mounted on the part 10, and the using surface of the plate 12 coincides with the laser beam emitting direction of the rangefinder 8. When the part 10 is steadily placed on the ground, the laser beam is immediately emitted to the plate 12, and the distance between both the paired plates 12. That is, since the plates 12 are respectively mounted at the paired parts 10, the distance between them (accurate value is already known) is measured.

IPC: H01J35/26
Filed: 1991-02-28
Abstract: PURPOSE:To provide a rotary cathode x-ray tube able to suppress the temperature increase of a rotary cathode or a rotary body as low as possible. CONSTITUTION:An electricity supplying brush 8 of an elastic metal plate made of a magnetic material and a cylindrical magnetic core 31 on which a coil 30 is wound are placed and fixed in the internal circumferential surface of a vacuum vessel 2 and a lead wire of the coil 30 is connected to an electric power source 32 through a switch SW installed outside the vacuum vessel 2. When ON operation of the switch SW is carried out, the magnetic core 31 wound with the coil 30 becomes an electromagnet and the electricity supplying brush 8 is attracted toward the magnetic core 31 and comes to a posture having no contact with a rotary cathode 4 or a rotary body 21. When the switch SW is turned off, it returns to the original position due to the elasticity and comes to a posture having contact with the rotary cathode 4 or the rotary body 21 and thus the heat generated in the rotary cathode 4 or the rotary body 21 is led to the outside of the vacuum vessel 2 through the electricity supplying brush 8.

Abstract: PURPOSE:To obtain an original reader which performs editing without using a memory by outputting the contents of information on a printed or handwritten original of full size and the information contents of a contracted original of a microfilm, etc., in the form of independent signals or a composite signal. CONSTITUTION:Information on an original of full size is passed through an optical system 1 to obtain an optical signal, which is converted by a photoelctric element 2 int an electric signal before being inputted to a processing unit 4 through a buffer amplifier 3. On the other hand, information on a contracted original of a microfilm, etc., is supplied to a photoelectric element 2' through an optical system 1' to perform photoelectric conversion, and the resulting signal is inputted to a processing unit 4' through a buffer amplifier 3'. Those signals are thus supplied to the processing units 4 and 4' to correct the ground dirtying and signal level independently, and the resulting signals are outputted at the same level and then superposed upon each other by an adder 5, which outputs one composite signal. The control over those operations is exercised by operating an electrical servomechanism control part 7 through an operation part 6, thereby controlling a photoelectric element scanner control 8, etc., for synchronizing the scanning start of the photoelectric elements 2 and 2'.

Title: Switching power supply
Inventor: KO BUNKEN
IPC: H02M3/28
Filed: 1992-02-14
Abstract: PURPOSE:To increase an efficiency and to reduce a noise and the cost by constituting a switching power supply of a self-excited DC-DC converter, etc., with automatic oscillation function-added simple circuits so that it may resonate only at the time of switching and by making a zero-volt switching possible. CONSTITUTION:When a FET5 is in an on-state, a magnetic flux of an iron core 23 of a saturable inductance 8 increases. When the saturable inductance 8 gets saturated, the FET5 gets turned off and a reactor 4 and a capacitor 10 resonate and a voltage between a drain and a source of the FET5 rises in the shape of a sine wave. Then, when a magnetic core 9 of a saturable transformer 2 is saturated, the reactor 4 and the capacitor 10 resonate and the voltage between the drain and the source of the FET5 drops in the shape of a sine wave. When the voltage becomes zero, the magnetic core 9 gets unsaturated and the FET5 gets turned off. Thus, the voltage of the FET5 at the time of a turn-on and a turn-off is made into the shape of a sine wave and a zero-volt switching is conducted for preventing a voltage peak.
