Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To attain optimum routing by using common subscriber information between exchanges. SOLUTION: In an exchange network system, where a plurality of relay exchanges 11, 12, 13 are installed, each of the exchanges 11, 12 13 discriminates connection propriety between each exchange and each subscriber on the basis of the idle state of channels contained in the exchanges, the exchanges mutually communicate idle and busy information edited for each subscriber, the exchange network system has sets of subscriber information 111, 121, 131 as common data and selects a channel, on the basis of the subscriber information as the common data. Thus, the occurrence of processing delay processing congestion and a call loss due to disabled channel acquisition can be reduced.

Title: Fuel injection quantity controller of internal combustion engine
Inventor: INAGAKI HIROSHI
IPC: F02D41/14
Filed: 1990-09-20
Abstract: PURPOSE:To prevent deterioration of drivability and characteristics of exhaust gas by correcting fuel injection capacity in order to restrain change of the fuel injection capacity at the time when a fuel behavioral simulation parameter is identificated in the state where an internal combustion engine is in a steady drive. CONSTITUTION:Wall surface attached fuel capacity (fw) attached on a suction pipe inner wall surface M4 is computed by a means M5 by way of using a simulation model showing a dynamic behavior of fuel in the neighbourhood of an injector M3 of each cylinder M2 of an internal combustion engine M1. The fuel injection capacity to each cylinder is also controlled by a means M6 on the basis of output of the means M5. Additionally, each parameter P.R used for each of the means M5, M6 is identificated on the basis of output of an air fuel ratio sensor M8 provided on an exhaust pipe M7 of the internal combustion engine M1. In this case, whether the drive state of the internal combustion engine M1 is in a stable state or not is discriminated by a means 10 to discriminate it. And when the drive state of the internal combustion engine M1 is in a stable state, the fuel injection capacity is corrected so that the range of change of the fuel injection capacity controlled by the means M6 comes to be smaller.

Filed: 1992-09-18
Abstract: PURPOSE: To perform splitting transfer in a system without restriction by loading the tap address of a transferred serial access memory. CONSTITUTION: A tap address TA is latched 12 through a buffer 11. When splitting transfer of VRAM is started, clock signals A-D are generated 14. The signal A has the reverse phase of an inverted RAS signal, and the signal B has the same phase as an SC signal. The signal C becomes a high state, when the output of a serial address counter AD is the last address of a split SAM during transfer, the signal D becomes a low state from a high state, according to the low state of an inverted CAS signal in a splitting transfer cycle and becomes high state after new TA is inputted to AD. From among the last address of SAM inputted to a control part 15 of the respective signals A-D during transfer and the falling edge of the inverted CAS signal in read transfer, a next tap address is impressed on AD 13 with a later timing.

Title: Semiconductor device
Inventor: TAKEI HIDEKI
IPC: H01L29/866
Filed: 1988-10-03
Abstract: PURPOSE:To enable operation without being subject to the effect of wiring resistance from a transistor for controlling the gate of an output transistor by connecting the diode elements of both channels to the gate of a transistor for a CMOS circuit connected to an output terminal. CONSTITUTION:When static electricity is applied to an output terminal 106 to which a transistor 101 is connected in a CMOS circuit, the diode elements 107-109 of both channels realized through the same means as the formation of the source or drain of the transistor 101 are used as a path through which charges excited through a gate insulating film are discharged to a power supply. Consequently, wiring resistance, etc., between a gate material to the diode elements 107-109 and the transistor are ignored by the method of arrangement of these diodes. Accordingly, voltage applied in the reverse directions of the diodes is brought rapidly to the state of plastic breakdown when it exceeds the reverse breakdown strength of these diodes without being subject to the effect of propagation delay by these wiring resistance, thus forming the discharge path of charges.

Title: Formation of pattern
Inventor: IMURA MIDORI
IPC: H01L21/302
Filed: 1983-12-26
Abstract: PURPOSE:To enable control of a pattern width with high accuracy by a simple method with a titled method for condensing an energy beam to the surface of an object to be worked in a liquid or gas by controlling the modulating frequency of said beam. CONSTITUTION:The laser beam 42 emitted from an energy source 31 passes through a modulator 32 and is focused by a lens system 33. The focused beam passes through a plating liquid 36 and strikes the surface of a metallic layer 39 on a substrate 38. The modulator 32 is mechanical, for example, rotary light chopper and it is assumed that the chopper is rotated at a certain frequency f1 and frequency f2=2f. The relation between the laser irradiation density and time in a part 45 irradiated with the laser is as shown in the figures (a), (b). Although the irradiation density per pulse of (b) is half the (a), the total energy in a specified time T is constant as the frequency is two-fold. The laser beam modulated to an optional frequency is obtd. while maintaining the specified total energy by changing continuously the rotating speed of the modulator 32 in the above-mentioned way. The width of the pattern to be formed is thus made adjustable with high accuracy.

Abstract: PURPOSE:To shorten an access cycle by directly extracting residual charges from a word line, and shortening the time necessary for the charges of a word line released from a selected-and-driven status to come in a completely non- selected status. CONSTITUTION:To a word fly-back line IST, a holding current drawing circuit 1 to flow a holding current Ist through respective memory cells M is connected, which lets a memory holding current Ist flow from the line IST to a negative power supply potential VEE side at all time by a reference voltage Vcs-Ist.

Accordingly, the residual charges of the word line W immediately after being released from a selection can be directly drawn from the line W itself.

Title: Voltage regulator
Inventor: NAKAMURA AKIRA
IPC: G05F1/56
Filed: 1985-11-08
Abstract: PURPOSE:To protect a control transistor from its breakage due to the discharging current by using a switching circuit that switches the substrate potential of the control transistor so that it is equal to the higher one of both levels of an input voltage source and the output voltage. CONSTITUTION:When Vin<Vout is satisfied between the input voltage and the output voltage, a transistor TR 53 is turned on and therefore the gate voltage of a TR 54 is approximately equal to the level of the Vout. Then the TR 54 is turned off. While the gate voltage is less than the source voltage with a TR 61 and therefore the TR 61 is turned on. Thus the substrate potential of a control TR 42 is approximately equal to the voltage Vout and therefore the P-N junction consisting of a P<+> area 23 and N<+> area 25 is adversely biased. Thus no current flows to the P-N junction part even in case a capacitor, etc. are connected between terminals 11 and 9. This prevents the breakage of the TR 42.
