Title: Rotary grinding machine
Inventor: YAMAGUCHI MASAO
IPC: B24B47/18
Filed: 1993-08-19
Abstract: PURPOSE:To unify the surface roughness of a ground face so as to improve appearance of a work ground face and reliability. CONSTITUTION:A detecting plate 8 having a slope 8a is fitted and fixed to a saddle 2, and a gap sensor 9 is mounted on a frame 1 opposite to the slope 8a. Hereby, when the saddle 2 is moved against the frame 1, the gap sensor 9 detects the distance between itself and the slope 8a of the detecting plate 8, and a controller C can discriminate the position of a table 7 against a grinding wheel 21 based on the detected value. It is constituted so that the rotating speed of the table 7 increases gradually as the rotational center position of the table 7 approaches the grinding wheel 21, and hence the circumferential speed of the table 7 can be set constant. In addition, the feed speed of the saddle 2 increases gradually as the rotational center position of the table 7 moves to the grinding wheel side, and hence the feed interval of the ground trace remaining on the ground face of a work W becomes constant.

IPC: B60W10/18
Filed: 1985-09-18
Abstract: PURPOSE:To prevent an engine stop from a sudden decrease of the engine rotation in braking, by controlling to disconnect the clutch when a wheel lock is very likely to be generated. CONSTITUTION:A processor 9a of an electronic control device 9 decides if the clutch 2 is connected or not depending on an input signal from a clutch stroke sensor 31. When the clutch 2 is disconnected, the processor 9a controls the clutch in an ordinary way. When the clutch 2 is connected, the processor 9a decides if a switch SW3 is ON or not. If the switch SW3 is ON, it means that the condition is in a sudden braking. Therefore, the processor 9a activates a clutch actuator 3 to control to disconnect the clutch immediately.

Title: Screw up device for rolling mill
Inventor: KIKUCHI TAKAO
IPC: B21B31/24
Filed: 1987-08-21
Abstract: PURPOSE:To improve the quality and thickness accuracy of rolled sheet stocks by installing a straight sensor provided with a detection bar and a detection head inside a screw up male screw and directly detecting a position of the screw. CONSTITUTION:A fixing case 18 fixing the top of a detection bar 19 is installed inside a screw up male screw 3, supporting plate 5, and a metal 6 and is anchored to a case 17.

Title: Cmos output buffer circuit
Inventor: SHIROTA SHIYOUZOU
IPC: H03K19/0948
Filed: 1983-11-01
Abstract: PURPOSE:To decrease a through-current by preventing simultaneous ON of two transistors (TRs) of an output buffer by providing two inverters having a different threshold value at the pre-stage of the CMOS output buffer. CONSTITUTION:When an input signal at an input terminal 10 is lower than a voltage Vth2, outputs of inverters 1', 1'' go both to H, a P-channel TRQ3 is turned off and an N-channel TRQ4 is turned on. When an input voltage is higher than the Vth2 and lower than a Vth1, the TRs Q3, Q4 are both turned off and no through-current flows. When the input voltage is higher than the Vth1, the TRQ4 is turned off and the TRQ3 is turned on. Since the two TRs do not turn on at the same time, the through-current is decreased remarkably.

Title: Current sense amplifier
Inventor: ANDORUU TEIMOSHII FUERISU
IPC: G11C7/06
Filed: 1990-08-03
Abstract: PURPOSE: To reduce an occupied space on a chip and electricity consumption by connecting an input element to one control node so as to receive signals on the other controllable electric path and controlling the controllable electric path with clock signals. CONSTITUTION: When clock signals ϕ are high, these Tr are biased to a saturation with the gate voltage of (p) channel transistors Tr 52, 54 and load Tr 58, 60, and output voltages are equally maintained regardless of the current difference between a data line DL and -DL. Also, when clock signals ϕ become low and Tr 56 is put OFF, the output voltage is driven in the inverse direction with the current difference to generate the output electric potential difference. The speed that the output electric voltage is driven in the inverse direction is increased with the feedback generated due to the cross connection of Tr 52, 54 and the cross connection of load Tr 58, 60. By this constitution, the occupied space on the chip of the circuit is reduced and also the electricity consumption is reduced because of the small number of the element.

Abstract: PURPOSE: To freely set an objective function when the objective function is constituted in the linear function of respective standby path installation numbers without depending on the initial value of the standby path installation numbers. CONSTITUTION: At a point P<(k)> inside an executable area, distances Di <(k)> with executable area boundaries in respective axial directions are obtained (a step S3.) Then, the point is moved in a direction where the distances for which weighting by the coefficient Ci of the standby path installation number Xi in the objective function is performed become equal (the steps S4 and S5) and repetition is performed until returning to the executable area (the steps S6 and S7.) Then, at the time of defining the respective standby path installation numbers as Xi <(l)> -αCi , a maximum α for satisfying a set relief rate for an optional transmission line fault is obtained (the step S8.) At the time of α<=ε(the step S9,) a processing is ended and Xi <(k+1)> at the point of time is defined as a solution.  At the time of α>ε, it is defined as Xi <(k+2)> =Xi <(k+1)> -αβCi (the step S10,) (k) is increased (the step $11) and the processing from the step S3 is repeated.

Abstract: PURPOSE:To make a judgement in the unit of one dot unnecessary and to draw a straight line at high speed even by a low-cost device by executing drawing by decomposing the straight line into vectors in a horizontal or vertical or 45 deg. direction. CONSTITUTION:An input means 100 inputs a start point and an end point or the difference from the start point and the end point. Here, when the start point is an origin (0, 0) and the end point is (m, n), a judging means 110 compares 2n and (m), it is judged that the straight line is decomposed into the horizontal direction at the time of 2n<(m), the straight line is decomposed into the 45 deg. direction at the time of 2n>(m) and the result is outputted. A decomposing means (horizontal or vertical) 120 and a decomposing means (45 deg.) 130 decompose respectively the straight line into vectors in the horizontal or vertical or 45 deg. direction by using a calculating expression to obtain the length of the vector derived from a quantizing rule in accordance with the judging result of the means 110 and obtain the lengths. A straight-line drawing means 140 draws a drawing dot string in accordance with the output of the respective decomposing means.
