Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of D/A conversion and A/D conversion. SOLUTION: A switch circuit conducts a selective operation that includes an action of discharging or charging selectively at least either of 1st and 2nd capacitors and an action of selective connection of both the capacitors so that electric charges are re-distributed between both the capacitors. In response to a circuit storing tentatively a digital value to be converted into an analog form, another circuit is provided and this circuit activates the switch circuit to conduct a selective operation sequence that repetitively causes re-distribution of charges by number of times being a function of the digital value to be converted into the analog form and after the operation, a voltage of at least one capacitor is an analog voltage that is converted from a digital value. Furthermore, the switch circuit repeats re-distribution of the charges between the 1st and 2nd capacitors to convert the analog voltage into the digital value.

Title: Manufacture of tough and hard steel for machine structure superior in delayed breaking resistance
Inventor: NAKAZATO FUKUKAZU
IPC: C21D8/00
Filed: 1981-12-25
Abstract: PURPOSE:To obtain titled tough and hard steel having >=125kgf/mm.<2> tensile strength by quenching from a specified finishing temp. after hot rolling as well as decreasing P content and by succeedingly tempering at a specified temp. under the existence of Cr. CONSTITUTION:A steel containing, by weight %, 0.18-0.28 C, <=0.5 Si, 0.5- 2.5 Mn, 0.5-4.0 Cr, <=0.01 P, if necessary >=1 kinds among <=0.1 Nb, <=0.3 V, <=0.003 B, 0.05 Ti and the balance Fe and inevitable impurities is hot rolled under a condition in which the finishing temp. becomes 900 deg.C. This is rapidly cooled from this finishing temp., succeedingly tempered at a low temp. of 400- 450 deg.C. Here, due to a restriction of P and a temp. condition at quenching, a segregation of P to grain boundaries of austenite is markedly suppressed and a brittleness of the austenite grain boundaries causing the later breaking can be prevented. The later breaking resistance is deteriorated at the tempering temp. lower than the lower limit and similar phenomena are observed at the temp. higher than the upper limit and the strength is markedly decreased.

Title: Detecting system for different-phase ground fault of distribution line
Inventor: YAMAMOTO HISAO
IPC: H02H3/00
Filed: 1989-08-17
Abstract: PURPOSE:To surely detect a different-phase ground fault associated with a fault-point resistance by providing a current changing width relay, ground-fault relay, and AND circuit which decides operations of both relays and deciding simultaneous operations of both relays as a different-point different-phase ground fault. CONSTITUTION:When, for example, a different-point different-phase ground fault associated with a high resistance occurs between points F1 and F2, a current changing width relay 51D and groundfault overvoltage relay 64 operate in response to the ground fault and a different-point different-phase ground fault detecting signal is outputted from an AND circuit 10. When a different- point different-phase ground fault is small in fault-point resistance and an input which can make an overcurrent relay 51F operable can be expected, the current level at the time of the different-phase ground fault can be decided by separately recognizing operations of the relays 51D and 51F1, since the relay 51F1 simultaneously operates.

Filed: 1981-12-30
Abstract: PURPOSE:To simplify the circuit constitution, by incorporating a circuit preventing timewise overlapping of access and a circuit providing the priority for the access signal for output with a monostable multivibrator. CONSTITUTION:When an access signal 2 is generated from an input/output circuit 22 during the generation of an access signal 1' through the operation of a block 23, an FF35 takes an access signal 2 as a clock and reads the state of an access signal 1, and a Q' output goes to a low L level. Thus, an output of a  delay circuit 36 can not pass through an AND gate 37 and the access signal 2  is inhibited. When the access signal 1 is lost, the FF35 is reset, the Q' output goes again to a high H level, then an output is generated from the AND gate 37  and applied to a common circuit block 38 as an access signal 2'. Response signals 1, 2 are generated with the end of the access signals 1', 2'.

Abstract: PURPOSE:To perfectly remove chromatic aberration, by making it possible to move a convex lens system along an optical axis so that the emitted light of a monochrometer can be formed into an image at the position of a specimen. CONSTITUTION:When monochromatic light having a desired wavelength is allowed to irradiate a specimen 2, the angle of rotation of a diffraction lattice 17 is adjusted to a predetermined position at first. Whereupon, the multicolor light emitted from a xenon lamp 1 is incident to the lens of the first convex lens system 6 directly or while reflected by a reflecting mirror 9. The light passing through the convex lens system 6 gathers to the incident slit 14 of an exciting monochrometer 7. At this time, the light having a wavelength component equal to the emitting wavelength of the monochrometer 7 is certainly formed into an image at the position of the slit 14. The light passing through said slit 14 reaches the lattice 17 through a plane reflecting mirror 15 and a collimator mirror 16 and only the light having a desired wavelength in the light diffracted by the lattice 17 appears on an emitting slit 20 and the emitted light passing through the slit 20 is incident to the second convex lens system 18. The light passing through the convex lens system 8 is certainly formed into an image on the specimen 2.
