Title: Transient darlington transistor circuit of high current amplification factor
Inventor: INOUE KIYOKAZU
IPC: H03F3/34
Filed: 1981-04-10
Abstract: PURPOSE: To obtain a large overcurrent with a small base current in the closing mode of a switch for a Darlington circuit, by inserting a transistor (TR) between an input stage TR and an output stage TR.  
     CONSTITUTION: The base is connected to the emitter of an input stage TR6 forming a Darlington circuit; the emitter is connected to the base of an output stage TR2; and the third TR10 connected with the collector is connected to a common collector of the TR6 and TR2. The current amplification factors of the TRs 6, 10 and 2 are referred to as hFE 6 , hFE 10  and hFE 2  respectively, and the collector-emitter voltage of the TR2 becomes higher than the sum of the hFE of these TRs. As a result the Darlington function is caused by the TRs 6, 10 and 2. The collector current IC flowing to the TR2 is set at the value obtained from an equation I in case when the current of the TR6 is referred to as IB 6 . Accordingly the current IB 2  of such transient Darlington TR can be set at 1/hFE 10  that obtained with no insertion of the TR10 to obtain a similar collector current with an extremely level of IB 2 .

CONSTITUTION: When water flows in a conduit line 10, a water flow in a conduit 2 is increased in speed and a drain valve 5 blocks a drain hole 4a of a pump chamber 4 as pressure on the output side of a gate valve 20 in the conduit line 10 is lowered in comparison with pressure on the inlet side by work of the gate valve which is a differential pressure generating body. Thereafter, pressure in the pump chamber 4 rises and pushes a pumping valve 7 to open, and the inside of a tank 6 is pressurized by the water flow to the inside of the tank 6. Thereafter, the drain valve 5 opens the drain hole 4a by negative pressure and dead-weight generated by influence of a pressure wave in the conduit 2. By repetition of such work, water in the tank 6 is gradually pressurized, and water pumping is carried out toward a water supplying part of an irrigated area, etc., through a water pumping pipe 8.

Abstract: PROBLEM TO BE SOLVED: To improve encoding efficiency by judging whether or not a code section for which a main section as a prescribed real number section corresponding to a last input symbol is divided is provided with the maximum value and minimum value of the main section and switching an output code based on the judged result. SOLUTION: In the case that the main section is provided with the maximum value and the minimum value (A), since it is the entire main section, the need of sending information for performing discrimination from other sections is eliminated and the output code of two bits is saved. Then, in the case that only the minimum value is provided (B), since a code to be surely outputted in the case of the other section is '1', discrimination is performed when '0' is outputted as the code and thus, the output code of one bit is saved. Then, in the case that only the maximum value is provided (C), the code to be outputted next in the case of the other section is '0', the discrimination is performed when '1' is outputted as the code and the output code of one bit is saved.  Then, in the case that neither maximum value or minimum value is provided (D and E), the section for which the output code becomes 01 and 10 is discriminated from the other section when either 01 or 10 is outputted as the code since the section is intrinsic.

Abstract: PURPOSE:To improve the self-running stability without change of a conventional hardware constitution by supervising an output of an integration control element at the normal mode so as to detect the self-running oscillation characteristic of a digital variable oscillator and controlling the self-running oscillation according to the said self-running oscillation characteristic when the digital control variable oscillator is transferred to the self-running mode through the interruption of input. CONSTITUTION:When a data for proportional control and integration control is received by a CPU9 from a phase comparison hardware section 8, a deviation from the normal value is obtained, a proportional element control variable and an integration element control variable are obtained and set to a prescribed register in the CPU9 at each prescribed period. When a clock input is lost due to some cause, the control system of a digital phase locked loop circuit DP-PLL control system enters the self-running mode. When the mode enters the self- running mode, since a digital control variable oscillator DCXO voltage controlled value is retarded by epsilon only at each prescribed period T, the self-running stability is improved remarkably.

Title: Correction of diameter of multi-blade cutter
Inventor: KOUDA SEIDOU
IPC: B23Q17/09
Filed: 1984-03-22
Abstract: PURPOSE:To fully automate setting and correction of the correcting amount of tool diameter by feeding back the machining accuracy of work to the correction level of the tool diameter while setting the limit of the tool diameter correction level. CONSTITUTION:To perform cutting of work while employing the setting correction of tool and to automatically measure the dimension of work upon completion. The results are compared with the dimensional allowance preset in an automatic measuring correction controller to perform automatic decision. In case of preliminary cutting, an error added with the finish margin is measured as a machining error thereby the measurement will exceed over the upper limit of dimensional allowance and since new tool is employed, the correction value is calculated from the measured value of work thus to correct the correction amount of tool in a numerical controller. Such corrected tool diameter correction amount is employed to perform machining again and if the dimension of work measured automatically upon completion of machining is within the allowance, mass production is executed while if it will exceed over the upper limit of allowance, it is corrected again and stops upon deviation from the lower limit. If the sum of correction amount exceeds over the setting level, it is decided to be the limit of service life.
