Title: Cutting off of work
Inventor: SAITOU TOSHINAO
IPC: B23D23/00
Filed: 1980-10-24
Abstract: PURPOSE: To improve the precision of a cut dimension by a method wherein a work is cut as a die is brought relatively into elastic contact with a cutter and the clearance between the cutter and the die is kept always at zero when the work is being cut.  
     CONSTITUTION: When an electrode 17 screwed in a base 18 is rotated right, the electrode 17 advances and pushes the back of a die 11. The die 11 is advanced by this push action and comes in contact with the cutter 10. When the electrode 17 is advanced further under such a state, a preliminary pressure is given between the cutter 10 and the die 11. When under this state a work 1 is cut by the cooperation of the cutter 10 and the die 11, the clearance between the cutter 10 and the surface of the die 11 always is kept at zero by the deforming pressure of the cutter 10 and the work 1 can be cut off with dimensional precision.

Title: Sense amplifier for dynamic random access memory
Inventor: SANGU HOO DOONGU
IPC: G11C11/409
Filed: 1988-06-17
Abstract: PURPOSE: To improve sense speed by installing a pair of cross-coupled FETs, a pair of bit lines and a voltage limiting means connected to at least a pair of connecting nodes. CONSTITUTION: The precharge of the memory bit lines 26, 28 of a cross-coupled sense amplifier is accomplished by equalizing two bit lines 26, 28 which are each charged to the power source voltage VDD and the threshold voltage VTP of a gate-grounded PMOS device. Since one node 32(34) of the sense amplifier holds the swing corresponding to the power source voltage VDD, it is conveniently coupled with the DATA bus. The swing of the signals of these bit lines 26, 28 is limited within the range which corresponds to the difference between the power source voltage VDD and the absolute value of the threshold voltage of PMOSs 10, 12. By this, the signal generating time in the sense is improved without exerting adverse effects on charge accumulation and the precharge level.

Title: Dynamic rom
Inventor: KOBAYASHI RYUICHI
IPC: G11C16/06
Filed: 1987-06-15
Abstract: PURPOSE:To attain the adequate operation by a precharge signal over a wide range from an ultralow frequency to a high frequency by adding a current mirror circuit and a logic circuit of simple constitution. CONSTITUTION:When a precharge signal pulse (a) is entered, a logic circuit turns on precharge transistors (TRs) 2, 3 to supply a current to a ROM. Thus, the data output node of the ROM is precharged to a power voltage. With no precharge signal pulse (a) given, the logic circuit gives an output power of the current mirror circuit 4 to the gate of the precharge TRs 2, 3. Thus, the precharge TRs 2, 3 are slightly turned on to supply a minute current to the ROM. In selecting the said current slightly larger than the leakage current of a P-N junction or the like, even when the frequency of the precharge signal pulse is very low, the decrease in the voltage of the data output node of the ROM is prevented.

Title: Radar equipment
Inventor: YASUFUKU MASAKI
IPC: G01S7/28
Filed: 1985-07-04
Abstract: PURPOSE:To accurately correctly detect a target even when a clutter and the target are present in the same range gate by performing a receiving strength comparison between main and subs systems by a comparator only for a reflected wave in a Doppler frequency range wherein no clutter is expected to be present to thereby remove the effect of the clutter. CONSTITUTION:Received signals which have passed the same range gates, for example, 5a and 5b of main and sub systems are divided into (m) signals corresponding to the Doppler frequencies of the received signals by (2m) BPF's 8all...8 a1m and 8b11...8b1m and outputted to detectors 611...61m and comparators 711...71m, respectively, for every Doppler frequency. On the other hand, the upper limit Doppler frequency of a clutter is calculated by a Doppler frequency calculator 9 to output signals to comparators corresponding to frequencies not larger than the upper limit Doppler frequency, stopping the generation of a detection stop signal. Therefore, since a interference-wave removing operation by the comparison between the received waves of the main and sub systems is performed only for reflected waves from a target in a Doppler frequency range wherein no clutter is present, a target detection stop by the clutter is checked and therefore the target is accurately detected.

Filed: 1986-06-25
Abstract: PURPOSE:To optimize control of the pressure condition, rotation speed and stoppage of a tool by providing an element for detecting the heat temperature of a tool and a circuit for judging the detection signal on the basis of a specified standard value, and by judging the machining condition according to the judgement signal. CONSTITUTION:In case of grinding the inner surface of a hole by inserting a rotating grindstone 1 therein, if the contact pressure is strong, generation of heat grows up and the heat is transmitted to a contact pressure member 7 from the shaft of the grindstone 1 and a chuck 2. Therefore, according to the temperature increase of a thermocouple temperature contact 9, an electric current flows in a lead 10 due to thermo-electric power. The electric current is then detected when it has passed through an energizing ring 11 and an energizing brush 12, while judgement of the detected signal is performed by a circuit integrated on a substrate 14. The judgement circuit is equipped with a Schmidt circuit whereby a phase inversion value is set for accurate judgement. It is thus possible to perform stable and accurate machining while maintaining constant load condition by controlling the pressure condition, rotation speed and stoppage of a tool.

Abstract: PROBLEM TO BE SOLVED: To allow a user to quickly decide a countermeasure for failures, that is, which part of application has problems and whether or not reinstallation should be operated, even if the user does not have special knowledge through obtaining the content of the failure by referring to a defective code list, based on a generated defective code. SOLUTION: At the time of detecting the forced end of a program 22, an OS 21 starts a failure diagnosing part 23, and transfers a defective code and the name of the forcedly ended program to a failure diagnosing part 23. A failure diagnosing part 23 retrieves a pertinent defective code from a defect code list 31. When any defective code can be retrieved, the content of the defective code and the name of the program are outputted from the failure diagnosing 23 to an output device 4. Afterwards, the number of times of references to the defective code is incremented by only 1, and each entry of the defect code list 31 is rearranged in the order of the defective codes which are more frequently referred to. However, when defective code could not be retrieved, the defect code list 31 is not updated.
