Title: Switched capacitor circuit and delta-sigma modulator using the circuit
Inventor: FUJIMORI ICHIRO
IPC: H03M3/02
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To attain a clock sequence that never causes the datadependent loading of a reference voltage source by using a switched capacitor circuit and a 4-phase clock sequence. SOLUTION: A delta-sigma modulator 56 has a feedback loop, and the value of 1-bit data 58 controls a D/A converter 54 and the data 58 is outputted from a quantizer 52 by a clock of high frequency f3 . Then the data 58 is expressed as a string of digital value including Y=-1 and Y=1. The value Y decide the v[ref+ or Vref -voltage that is supplied to an addition node 48. The converter 54 can be expressed as a switched capacitor, and the data-dependent loading of a reference voltage source is substantially eliminated by controlling the value Y of the converter 54 and a 4-phase clock.

Abstract: PURPOSE:To prevent jamming of work and to efficiently produce a cartridge by forming and working a blank, which is cut to prescribed dimensions, with the design face side turned upward. CONSTITUTION:Rectangular blanks 1 cut to strips are sucked and held one by one by a suction device 2, and each blank 1 is sent by a carrier claw 3 with the outside design face turned upward and is subjected to notching, one side lip 90 deg. bending, and scaphoid bending by means 4, 6, and 7 respectively with the outside design face turned upward. Since the blank 1 is formed and worked with the outside design face turned upward in this manner, the blank is worked while having the central flat part supported in a wide area by a lower mold of the scaphoid bending device 7 in the scaphoid bending process, and jamming scarecely occurs. In this system, it is very preferable that an inverting device which inverts the blank formed and worked to a scaphoid shape is provided before sticking of a plush ribbon 8.

Title: Time measuring device
Inventor: HONDA TAKAYOSHI
IPC: G04F10/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To always exactly measure the time intervals of two successive interrupt signals. SOLUTION: In a KCS(for knock control system) microcomputer 20 in an ECU(electron control unit) 1, an NE (interrupt) signal is input at every specific crank angle in a CPU 23. The time at the interrupt of NE signal is latched 32 in a capture register by the count value of a free running counter 31. If interrupt demand of an NE interrupt processing and overflow interrupt processing overlap in a specific interrupt prohibition period, the CPU 23 judges which interrupt demand generated. If the interrupt demand in overflow interrupt process generated earlier than the interrupt demand in NE interrupt process, the CPU 23 adds only 'unity' of overflow times in the free running counter 31 at that moment and calculates the necessary time of the successive NE signals using the added value. The CPU 23 also decrement overflow times by one in preparation for the next NE interrupt.

Title: Magneto-resistance effect head
Inventor: TOKUYADO NOBUHIRO
IPC: G11B5/39
Filed: 1981-06-17
Abstract: PURPOSE:To hold stably the orientation of magnetization at the initial value, by tilting the magnetization of a magneto-resistance element to the surface of a recording medium and at the same time forming a cut to a part of the magneto- resistance element with the orienting angle of the magnetization of the magneto- resistance element. CONSTITUTION:The magnetizing direction of a magneto-resistance element (MR element) 4 that senses the change of a magnetic field as a change of the resistance value is oriented by angle theta of inclination to the lengthwise direction. At the same time, a cut 5 is given to the back of the element 4 with angle theta. As a result, the counter magnetic field of the element 4 is not in the direction of the height (h) but in the oblique direction (a). Thus the magnetizing direction can be easily held at the initial value theta, and accordingly, a large bias magnetic field is not required for the element 4.

Abstract: PURPOSE:To enable detection of the contact resistance of a disconnector with a hot-line condition remained as it is. CONSTITUTION:A detector for contact failure is composed of electrode parts 12 in contact with the fixed contacting parts 3 and 4 and movable contacting part 5 of a disconnector 1; a D.C. current generation circuit 13, feeding D.C. current between the electrodes; and a voltage detecting circuit 16, detecting the electric potential difference between both contacting parts. Consequently in the disconnector 1 in a hot-line condition, voltage, in which a D.C. current component is added to a load current component generated by A.C. flowing in a bus bar, is detected in the voltage detecting circuit 16, by feeding a fixed D.C. current from the D.C. current generation circuit 13 in a condition, where the electrode parts are brought into contact with both contacting parts in the disconnector 1 in the hot-line condition. Because of the large fluctuation of the load current component, a correct electric potential difference between the electrode parts can be detected to know the contact resistance between both contacting parts by performing treatment to take up only the D.C. component from the detected voltage.
