Patent JP-H07167899-A (JP)
Title: Contact type ammeter
Inventor: KAGAMI SUETSUGI
IPC: G01R19/00
Filed: 1994-02-08
Abstract: PURPOSE:To enable measurement of a current,only by contact with a conductor by disposing four coils in two upper and lower stages symmetrically so that they hold a contact surface between them. CONSTITUTION:Coils 1 and 4 and coils 2 and 3 are disposed in two upper and lower stages symmetrically so that they hold a Ushaped contact surface 6 of CT 5. When a conductor brought into contact with the contact surface 6 is a thin conductor P1, a large output is generated in the coils 2 and 3 and a small output in the coils l and 4. When the conductor brought into contact with the contact surface 6 is a thick conductor P2, the small current is generated in the coils 2 and 3 and the large output in the coils 1 and 4, since a current flowing through the conductor as a source of generation of a magnetic flux is the same as a current flowing through a point Q. In the case when current values are the same in the conductors P1 and P2 and each current flows independently of other, the same value is outputted when the coils to 4 are connected in series. At the the when a conductor has an intermediate thickness between the conductors P1 and P2, setting is made beforehand in such a manner that gaps are formed for correction between the coils 1 and 2 and between the coils 3 and 4 so that the sum of outputs of the coils 1 to 4 be the same as that in the case of the conductor P1.

Title: Latching-up preventing structure of cmos transistor
Inventor: SATO SHIGEO
IPC: H01L27/08
Filed: 1988-02-17
Abstract: PURPOSE:To prevent lathing-up from occurring by connecting to an external power supply a conductive layer connected to a substrate formed on the bottom of a separating groove provided between conductive wells. CONSTITUTION:The title transistor includes an insulating layer 21 of about 5000Angstrom  thickness composed of SiO2 for example, intervened between a semiconductor substrate 1 and a conductive layer 22, and disposed around a heavy metal implantation region 12, the conductive layer 22 in which polycrystalline silicon is buried, and a substrate contact layer of Al for example connected to the upper end surface of the conductive layer 22. The polycrystalline silicon buried in the conductive layer 22 includes a high concentration impurity of the same P-type as that of the substrate 1. The region 12 is connected to the substrate contact layer through the layer 22 and to the external power supply. Holes, which recombine with minority carriers through a life time killer, flow into the power supply VSS as a current As through the layer 22. Hereby, parasitic NPN transistors Q2, Q1 formed between wells 2, 3 are not operated, thus preventing latching-up from occurring.

Title: Control circuit of switching regulator
Inventor: MATSUMOTO TETSUYA
IPC: H02M3/00
Filed: 1990-02-14
Abstract: PURPOSE:To make it hard to be affected by external noise by comparing the signal, to which the error output between the output signal of a sample holding circuit and the reference voltage is interpolated, with the output signal from a chopping wave generating circuit so as to change the pulse width. CONSTITUTION:An error operating circuit 3 outputs the error between the signal sampled by a sample holding circuit 1 and the output signal of a reference voltage generating circuit 2. An interpolated filter 4 interpolates the signal generated in the error operating circuit 3. A PWM comparator 6 compares the output signal of the interpolated filter 4 with the chopping wave outputted from a chopping wave generating circuit 5 so as to control pulse width. Since the control is performed with the sample value system this way, it is resistant to noise, besides since the interpolated filter 4 is used, the operating speed of the entire system improves, with the operation speed of the error operating circuit 3 intact.

Filed: 1988-02-16
Abstract: PURPOSE:To prevent the production of projected and recessed portions of a fine pitch on the surface of a circular thin plate by connecting the first and second pores to an air passage formed between the lower surface of a loading member and the base of a groove for the loading member to be connected to an external vacuum device. CONSTITUTION:A circular thin plate 2 loaded on a loading member 3 is vacuum- sucked through pores 4a, 4b and air passages 5, 6 and fixed. At this time, an outer peripheral side O-ring 7 mounted in a groove for the outer peripheral side O-ring and an inner peripheral side O-ring 8 mounted in a groove for the inner peripheral side O-ring closely contact a circular thin plate 2 to intercept circulation of air with the outside. The circular thin plate is thus fixed onto the loading member 3 fitted to a base material 1 by vacuum suction, so that the circular thin plate 2 can be smooth without irregularity because the upper surface of the loading member 3 is smooth. Accordingly, an optical disc, a wafer and the like can be manufactured in such a manner as to have smooth surface without projected and recessed portions of a fine pitch, so that the quality is excellent.

Title: Hot reuse method for tundish
Inventor: ITAKURA TAKASHI
IPC: B22D11/10
Filed: 1991-02-28
Abstract: PURPOSE:To finish a continuous casting in a state that the molten steel quantity remaining behind in a tundish is small and also, to decrease the melting loss of a refractory at the time of eliminating a residue. CONSTITUTION:Before continuous casting is finished, on the surface of a molten metal of the upper part of a molten metal pouring nozzle of a tundish, a float 4 in which the diameter of its maximum part is larger than the diameter of the molten metal pouring nozzle, whose average bulk specific gravity is smaller than specific gravity of molten steel, and also, larger than specific gravity of slag is thrown in, a molten metal pouring nozzle 2 is closed by the natural lowering of this float, thereafter, the residue is heated and melted, eliminated, and reused. Since the molten steel quantity which remains behind in the tundish is small, the damage of a refractory caused by slagging at the time of heating and melting the residue is very small, and hot repeating utilization of the tundish can be attained without requiring repair.
