Title: Device and method for predicting result of branch instruction
Inventor: KATSUTAMURI EKANADAMU
IPC: G06F9/38
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for predicting a branch result by using a history table in which content orientation predictors relating to one or a plurality of branch instructions are recorded. SOLUTION: A context orientation predictor is derived by integrating branch predictor vectors in respective entries of the history table. This vector comprises two predictors [(n) is optionally set and, preferably, fixed according to an execution style] for each value of (n). When the history table is accessed through the prefetch operation of a processor, the vector of a predictor as to a given branch named an ancestor branch is taken out of the history table and stored. After (n)-time fetching, the operation history of final (n) branches is used to gain access from a predictor vector relating to an (n)th ancestor of a next appearing branch to the predictor. The predictor is used to predict an (n)th decendant branch of the ancestor branch.

IPC: G10K11/162
Filed: 1993-04-14
Abstract: PURPOSE:To improve a soundproof effect without increasing the basis weight of a sound shielding material at all and to decrease the weight of the sound shielding sheet itself when the soundproof effect of the same extent is requested by specifying a binder component at 20 deg.C and compounding this binder component at a specific ratio or above of the entire component.

The material contains >=10wt.% rubber component having >=0.5 coefft. of loss at 20 deg.C. A sufficient effect is not exhibited in vibration attenuatability if the coefft. of loss at 20 deg.C is <0.5. The coefft. of loss is too low and the desired soundproof effect is not developed with the compd. contg. <10wt.% rubber compd. or thermoplastic resin component. As a result, the vibration attenuatability of the sound shielding sheet is improved and the excellent soundproof effect is obtd.

Title: Automatic speed change gear
Inventor: OKITA KINYA
IPC: B60W10/10
Filed: 1982-06-28
Abstract: PURPOSE:To enable a driver to prohibit the shift change operation that is unnecessary judging from the road traffic status by giving the driver notice of a shift change before a speed change point. CONSTITUTION:When a speed gear position is the second speed, load P reaches a point B on an alarm curve where the revolution is raised from a point A of the revolution q1 to q2, CPU is adapted to send an alarm operating signal to an alarm chime to produce an electronic sound from the alarm chime. When the revolution is further raised from q2 to q3 to change from the point B to a point C on a speed change curve, the CPU is adapted to send a shift-up signal to a shift actuator to shift the speed change gear position from the second speed to the third speed. At this time, if ringing is produced from the alarm chime, a driver judges the need of shift change operation of an automatic speed change gear from the road traffic status before under his eyes. If unnecessary, the driver manually prohibits the shift change operation.

Title: Developer concentration controller
Inventor: KIKUCHI KATSUNORI
IPC: G03G15/08
Filed: 1984-05-30
Abstract: PURPOSE:To detect concentration securely with relatively simple constitution even if an environmental change or change in the lapee of time is made by allowing variation in sticking characteristic with the resistance of a developer and that accompanying the resistance variation to cancel each other, and holding the developer concentration of a detected body constant. CONSTITUTION:A DC power source 42 for prevention against ground fogging is connected to a developing roller 34, which is impressed with a DC bias. A DC power source 43 is connected to a probe 37 through a resistance 44. Therefore, when the resistance value RD of toner 32 increases, an impressed voltage V drops, so the sticking characteristic of the probe 37 decreases, and when the resistance value RD of the toner 32 decreases, the impressed voltage V rises, so the sticking characteristics of the probe 37 increases. Further, the sticking characteristic of the toner 32 decreases as its resistance value RD increases. Consequently, the sticking characteristic variation due to variation in the resistance value of the toner 32 and the sticking characteristic variation due to the variation in the impressed voltage to the probe 37 accompanying the resistance value variation of the toner 32 cancel each other and the concentration of toner sticking on the probe 37 is held constant.

Title: Paper or sheet separation and take-out device
Inventor: TOMINAGA TAKASHI
IPC: B65H3/06
Filed: 1979-08-31
Abstract: PURPOSE: To reduce skews of papers or sheets and enhance the reliability of operation of a paper or sheet separation and take-out device, by providing rollers having grooves on their peripheral surfaces and other rollers, which are fitted into the grooves, in the positions of passing of both the ends of sent-out paper and by placing the intersection points of both the rollers at or in front of the point of pressure contact of the paper with a feed roller.  
     CONSTITUTION: One of horizontal sheets of paper is takne out by a pick-up roller 7 so that the lower end of the sheet 1 is sent to the positions 9 of intersection of stopper rollers 8 with gate rollers 5 and to the position 10 of pressure contact of a feed roller 2 with a friction member 3'. Since the positions of intersection 9 of the stopper rollers 8 with the gate rollers 5 are located at or in front of the point 10 of pressure contact of the feed roller 2 with the friction member 3', the sheet 1 is swung and has its skew corrected due to resistance during passing through a gap 6 even if the lower end of the sheet 1 is skewed and its one end reaches the intersection point 9 earlier than the other end. Thus, the skew of the sheet is reduced, an enough frictional force is ensured and the reliability of operation is enhanced.

Abstract: PROBLEM TO BE SOLVED: To utilize a general purpose inverter, by controlling an output frequency corresponding to change of an output voltage when this output voltage is higher than the lower limit voltage, and then stopping the operation of inverter when the output voltage becomes lower than the lower limit value. SOLUTION: This controller 1 is used in a pump drive apparatus for supplying a drive power to an induction motor M for driving a fountain pump P by converting an DC output power with an inverter using a solar battery S as the power supply. A frequency instruction F is inputted to the inverter I for changing an output frequency of an inverter I corresponding to change of an output voltage exceeding the predetermined allowable voltage range of the optimum operating point set on the I-V characteristic, by detecting an output voltage of the solar battery S. As a result, since the general purpose motor drive inverter can be driven with an output of the solar battery, apparatus cost can be reduced remarkably.
