Title: Hydraulic type damping device
Inventor: JIYANNPOORU BUUURU
IPC: F16F13/00
Filed: 1991-05-16
Abstract: PURPOSE: To improve the range in which optimum damping can be attained in a hydraulic vibration damping device connecting two chambers together with a restricted passage. CONSTITUTION: A restricted passage comprises three passages, namely a passage 4 whose flow area remains constant and passages 5, 6 whose flow cross sectional areas are adjustable successively from a zero value to a maximum value by two rotary cams 9, 10 mounted on the same shaft 11.

Title: Method for reducing stall torque of alternating current dynamometer
Inventor: KOKETSU MASATOSHI
IPC: H02P27/06
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To simulate on a road in a considerably low speed range when a transmission or the like is to be tested, by reducing a stall torque of an output shaft a.c. dynamometer. SOLUTION: In control circuits (11-33), an a.c. dynamometer DY is preliminarily excited by an excitation current-setting device 16 so as to increase a speed or torque quickly from that at a zero rotation, thereby to hold a magnetic flux of a motor of the dynamometer. An excitation current-reducing circuit 17 is provided in the circuits to reduce an excitation current from a% to 100% in a considerably low speed range rising from a detection speed Ndet of 0. A signal of the circuit 17 is multiplied by the excitation current from the setting device 16 at a multiplier 18. Accordingly, a constant output excitation current command output from a constant output excitation control circuit 19 is changed from a% to 100% in the considerably low speed range, and the excitation current in the considerably low speed range is reduced. A stall torque of the dynamometer DY is reduced in this manner.

Title: Transmitting/receiving change-over circuit
Inventor: TAKEYAMA HIROAKI
IPC: H04M9/08
Filed: 1985-05-25
Abstract: PURPOSE:To prevent an malfunction due to an ambient noise generated steadily by comparing a transmitting signal and a receiving signal only when the voice level is large compared with the level of the ambient noise. CONSTITUTION:While the ambient noise is steadily inputted from a microphone 31, the output of smoothing circuits 11 and 12 comes to be equal, and the output level of a comparing circuit 13 comes to be L. Consequently, a switch element 16 is a service interruption, the input from the transmitting side is not received to a comparing deciding circuit 15 and the input only from the receiving side is received. Next, when the voice of the prescribed level or above is inputted, until the output level of the smoothing circuit 12 comes to be sufficiently large, the output level of smoothing circuit 11 which rises rapidly is made larger, and during this period, the output level of the comparing circuit 13 comes to be H. As this result, the output level of the comparing deciding circuit 15 comes to be H, an impedance element 21 inserted to the transmitting signal line comes to be a low impedance and the transmitting condition is obtained.

Title: Arithmetic unit
Inventor: TAGAWA SHIROU
IPC: G06F7/527
Filed: 1977-09-21
Abstract: PURPOSE:To decrease the calculation step number of multiplication and thus to reduce the multiplication execution time, by setting the multiplication indicating flag to carry out an addition regardless of the value of the lowest-ranked bit. CONSTITUTION:It is only when a multiplication is carried out that port address A of RAM2 is desired to be altered via lowest-rank bit LSB of shift register SR5 and at the arithmetic unit. In this connection, bit (flag) M is added by one bit to microprogram MP and is set to ''1'' only when the multiplication is carried out. If this bit is set to ''0'', the output of NAND gate 21 features ''1'' at all times and the value of RA3 of pipeline register 8 (to which the output of ROM2 storing MP is set) is supplied to A-port address input A3 of RAM2. In other wirds, the value of M is always set to ''1'' in the case of multiplication, so ''0'' is supplied to A3 regardless of the value of RA3 in case the value of LSB of SR6.

Title: 3-phase 5-leg type iron core for transformer
Inventor: MATSUDA TAIJI
IPC: H01F38/38
Filed: 1978-09-13
Abstract: PURPOSE: To give a fixed relation between the size of the four rectangular hollow portions and the sectional size of a 3-phase 5-leg iron core for raising material yeild and for keeping the magnetic flux of the various portions of said iron core within a fixed limit of density when normal operation is underway and said one-wire earthing is provided.  
     CONSTITUTION: The length l and width w 1  of rectangular hollow portions, the width w 3  of yokes, the width w 3  of inner legs, the width w 4  of outer legs, and the length L of an iron core are fixed at w 1 =w 2 , 4l=L, 3w 3 +2w 4 =L-4w 2 . No waste is produced if a silicon steel plate with length L and width 2(1+2w 2 ) is punched for obtaining rectangular pieces c 1 -c 4  and said yokes. On normal operation, the voltages applied on the primary coils of phases are balanced, and no magnetic flux occurs to the no-coil legs N. When U-phase is earthed, however, the magnetic flux of the iron core legs of V- and W-phases become 3 1/2  of that ϕ obtained on normal operation and ϕ×3/2 at said legs N. Since width w 4  is large, however, magnetic flux density does not become so large and is kept within a required limit. Thus, a 5-leg type iron core for transformers which is readily adaptable for the restriction due to the error of transformation ration can be obtained.

Filed: 1986-05-20
Abstract: PURPOSE:To reduce an edge-sagging phenomenon during finishing polishing, to eliminate the error of thickness in a substrate and to form an element island having a uniform thickness by shaping an insulating film functioning as a polishing stopper on finishing polishing to the outer circumference of the substrate. CONSTITUTION:V-shaped grooves 16 for isolating elements are formed to the surface of a substrate 11 while an inverted trapezoid groove 17, the bottom of which has a flat surface, is shaped to the outer circumference of the substrate. An insulating film 18 for isolating the elements and a supporter layer 19 are formed onto the whole surface of the substrate containing the grooves in succession. The substrate 11 is polished and removed until the bottoms of said V-shaped grooves are exposed from the substrate surface side on the reverse side of the supporter layer 19. The insulating film 18 on the bottoms of the inverted trapezoid grooves 17 functions as a polishing stopper on the polishing. Accordingly, an edge-sagging phenomenon which has been observed during finishing polishing can be reduced, and the error of thickness in the substrate due to dispersion in a pre-process can be corrected, thus forming element islands having auniform thickness extending over the whole substrate and high accuracy.
