Title: Peak voltage detection circuit
Inventor: YANAGISAWA KOJU
IPC: G01R19/04
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a peak voltage detection circuit which can detect the peak voltage of an input analog signal having frequency higher than that of the clock input signal of a counter. SOLUTION: When an input analog signal has a voltage level higher than that of an output signal from a digital/analog converter(DAC) 7, a voltage comparator 4 generates an output signal which is inputted to a flip-flop 5 with an asynchronous set and synchronized with a clock input signal of an n-bit counter 6. The n-bit counter 6 counts up when an output signal EN from the flip-flop 5 with an asynchronous set validates the clock input signal. When the output voltage from an n-bit DAC 7 exceeds an input analog signal, count operation of the n-bit counter 6 is stopped and the output signal therefrom is converted through the n-bit DAC 7 into an analog voltage thus outputting a detection voltage.

Title: Analog/digital converter
Inventor: SUHARA SHIGEFUMI
IPC: H03M1/36
Filed: 1983-12-20
Abstract: PURPOSE:To measure various characteristics of an A/D converter at a high speed and with high accuracy by providing a selector part and a counter part at the stage after a comparator which compares an analog input signal with the reference voltage and reading out the value of the counter. CONSTITUTION:Comparators 21-215 compare the analog input signal Vi with a reference level of the DC partial voltage divided by a resistance and deliver the comparison output to a selection circuit 4. The circuit 4 selects the changing points 0 and 1 of the outputs of comparators and supplies these points to analog switches SW51-SW530. For analog switches SW, the odd SW51-SW529 are turned on when the test control input Tc is set at 1 to supply the inputs to counters 71-715 through the output of the circuit 4. Then the output of the circuit 4 is supplied to a decoder 8 after even switches SW52-SW530 are turned on when the input Tc is set at 0. The counter accumulates the input times given from the circuit 4 and reads them out to a terminal 9. Then the counter value is read out via a terminal 10 when the readout control input Rc is applied to. Then the characteristics of an A/D converter are measured. The decoder 8 converts the input signals into digital outputs D0-D3.

Title: Tape guiding method for clad bar production
Inventor: OOTA MASAHIKO
IPC: B23K20/04
Filed: 1985-10-30
Abstract: PURPOSE:To guide a clad tape to the prescribed position of a base metal and to manufacture a long sized clad bar by guiding the clad tape with the recessed groove on the tape guide face in about cylindrical shape which has a limited radius and center angle and makes the axial direction intersecting at right angles with the tape traveling direction. CONSTITUTION:A clad tape guide 16 is taken to have the sliding face with 20-50mm radius and the center angle theta of 20 deg.<=theta<=90 deg. and the axial direction is formed at right angles with the traveling direction of a tape 1. It is then guided on a base metal 2 by fixing the position of the clad tape 1 with the recessed groove 15 provided on the surface of the clad tape guide 16. Consequently, the stiffness against the force in the width direction of the clad tape 1 is increased and it is facilitated to guide the tape position constantly. The local wear of the guide 16 and the scratch flaw of the tape 1 can be prevented due to the contact pressure between the clad tape 1 and guide 16 becoming uniformly.

Abstract: PURPOSE:To continue a service by switching to the service of a general telephone sat in the power failure of a commercial power source in a customer system by switching an ISDN terminal and the general telephone set corresponding to the state of the commercial power source in an ISDN subscriber residence. CONSTITUTION:When the power failure occurs in the commercial power source in the customer system, a customer network terminating device (NT) 3 automatically connects a subscriber line 6 to a jack 4, and in an exchange, an ISDN layer synchronism supervisory circuit(SUP) 9 detects the step out of a layer 1 for a constant period, and reports it to a CPU 15 via a CPU bus 14. The CPU 15 drives a relay(Rb) 7 by issuing an instruction to a relay drive instruction input/output port (I/O) 12 via the CPU bus 14. A contact rl is set at a state shown in broken line by the operation of the RL 7, and the subscriber line 6 is switched to a general telephone subscriber termination circuit(SLC) 10 side. At this time, the CPU 15 performs a call processing by judging the outgoing/incoming call of the SLC 10 as the one identical to that of an ISDN layer termination circuit(DLC) 8. In such a way, a telephone service can be offered by using the general telephone set (TPH) 5 in the power failure of the subscriber residence.

Filed: 1990-09-17
Abstract: PURPOSE:To offer a two-component developing agent for electrostatically charged images which provides excellent charge exchangeability between additional toner and carriers and is fast in the startup of electrostatic charging in continuous copying operation by incorporating carrier particles which are prepared by dispersing magnetic particulates in binding resin, toner particles, and titanium oxide particulates containing a specific amount of Na2O. CONSTITUTION:The toner of the developer for electrostatically charged images consists principally of binding resin and a coloring agent. Carriers on the developing agent are a magnetic powder dispersion type and consists principally of binding resin and magnetic powder. The titanium oxide particulates which are added to and mixed with the toner and carriers, preferably, have 20 - 90m<2>/g specific surface area and 0.05 - 0.20mum primary particle size.
