Inventor: AKAGI YOSHIHIKO
IPC: F02D45/00
Filed: 1994-12-13
Abstract: PURPOSE: To suppress a rotation fluctuation due to a load fluctuation by estimating an amount of air passing through an auxiliary machine load air amount control valve when a deviation from the target number of revolutions in an idling state and a rotation fluctuation are prevented from occurring through correction and control of an intake air amount. CONSTITUTION: An engine revolution speed control device comprises an IC valve 54 to effect control so that the number of idle revolutions of an engine 162 is adjusted to a value approximately similar to a target value; an auxiliary machine load air amount control valve 13 arranged in such a manner to bypass a throttle body 159 so that the load of a power steering pump 165 by which a load fluctuation is caused is corrected. From the measuring result of an air flow meter 1 and a sum of an amount of air passing a throttle valve in a throttle body 159 and a leak air amount of a throttle valve, an estimation feed air amount is determined.  A difference between the measuring result of the air flow meter 1 and an estimated feed air amount is determined to estimate an amount of air passing an auxiliary machine load air amount control valve 13, and an ISC valve 54 is driven and controlled according to a change amount per unit time of the passage air amount.

Title: Method for jet pulverizing of silicon particle
Inventor: KIN KIEI
IPC: B01J8/24
Filed: 1992-11-18
Abstract: PURPOSE: To provide a jet pulverizing method of silicon particles which can efficiently produce silicon particles with a specified particle diameter. CONSTITUTION: Silicon particles having about 300-3,000 μm particle diameter range are supplied into a pulverizing chamber 2 through a feeding port 9. The silicon particles near a nozzle 3 are pulverized by colliding with each other with a jet air flow, having about 300-10,000 m/s flow rate at a nozzle outlet 3', through the jet injection nozzle 3. The silicon particles pulverized so as to have their diameters equal to or less than a specified value are discharged to the outside of the pulverizing chamber 2 through a discharging port 4 by adjusting average gas flow rate in the pulverizing chamber 2 within about 0.5-30 m/s.  A silicon particle layer flowing within the pulverizing chamber 2 forms a dilute-phase fluidized layer without an upper boundary by adjusting supplying speed of the silicon particles so as to maintain about <=0.2 particle density from the nozzle outlet 3' to the discharging port 4 and by making the discharging port 4 narrower than a cross-sectional area of the pulverizing chamber.

Title: Inkpot
Inventor: YAMAMOTO NOBUYUKI
IPC: B25H7/04
Filed: 1993-11-15
Abstract: PURPOSE:To facilitate winding of thread by arranging a tension pin in the vicinity of a pulley on which the tread is wound and winding the thread on the pulley after hanging the thread on the tension pin. CONSTITUTION:A tension pin 10, on which thread 11 is hung, is arranged in the vicinity of a pulley 3. When the thread 11 rounds approximately a half of a circumference from a winding starring point 13 on the pulley 3, the thread 11 is separated from the pulley 3 at this point and heads for the tension pin 10. On the tension pin 10, the thread 11 changes its destination into the direction which makes an acute angle or an approximately right angle with the thread 11. In this process, tension working on the thread 11 is increased by means of frictional force of the tension pin 10. Then, the thread 11 reaches the pulley 3 again to be wound. In this way, the thread 11 can be wound on the pulley 3 without generating any slackness.

IPC: G02B27/28
Filed: 1986-12-26
Abstract: PURPOSE:To improve the characteristic deterioration caused by a phase error, by forming that which has connected in series two pieces of 180 deg. phase shifters whose phase error characteristics are equal, as one pair, placing in series several pairs thereof, and specifying an angle of a phase difference inserting surface of the 180 deg. phase shifter. CONSTITUTION:A polarization plane rotary device is constituted of one pair of two pieces of 180 deg. phase shifters 15, 16 whose phase error characteristics against a frequency and a temperature are equal, and as for the first 180 deg. phase shifter 15, its phase difference inserting surface is inclined by an angle 3alpha/4 from an X1 axis, and as for the second 180 deg. phase shifter 16, its phase difference inserting surface is inclined by an angle alpha/4 from the X1 axis. According to this constitution, an input linear polarized wave 11 inclined by an angle alpha from the X1 axis rotates by the angle alphaand converted to a polarized wave 12 in the X2 axis direction. Accordingly, even if said polarized wave becomes a polarized wave shifted from C0 as a point C1 and C2 by a phase error of the first 180 deg. phase shifter 15, the second 180 deg. phase shifter 16 operates so as to negate them, therefore, each of them is converted to a polarized wave of the vicinity of a point X. In such a way, a power ratio of a main polarized wave component and an intersection polarized wave component, namely, deterioration of an XPD characteristic is reduced.

Title: Method for processing track crossing signals
Inventor: IWASHITA TAKAHIRO
IPC: G11B21/08
Filed: 1990-11-16
Abstract: PURPOSE:To accurately control a movement between tracks by providing a through-rate restrictive circuit in the control circuit for movement between tracks. CONSTITUTION:The through-rate restrictive circuit 2 is provided in the control circuit for movement between tracks. The track error signals generated from an optical head 1 contain a track loss signal as well as a noise caused by damage in a prepit or an optical disk. When these signals are inputted into the through-rate restrictive circuit 2, the track loss signals hardly affected by noise are obtained. By receiving these signals, a speed detecting means 4 outputs a speed signal, simultaneously, a target speed generating means 3 counts the number of passing tracks by receiving these signals, and outputs a target speed. In addition, a speed error signal is generated by a speed error detecting means 5, and in response to this signal, a driving motor 7 is driven through a driving amplifier 6 to control the optical head at a target speed. In such manner, seeking a track that is not a target track by mistake is prevented.

Title: External synchronizing circuit for controlling oscillation period
Inventor: OZAKI TOSHIO
IPC: H03K4/90
Filed: 1988-12-08
Abstract: PURPOSE:To simplify the circuit constitution by providing a terminal to which an external synchronizing signal having a larger absolute voltage than that of a reference voltage and a current limit element connected between the said terminal and a capacitor charged with a prescribed time constant whose terminal voltage is varied. CONSTITUTION:An external synchronizing signal S2 applied to a terminal T1 at a time interval between t1 and t2 is fed to a capacitor Ct via a diode D and a current limit resistor R3. Then the capacitor Ct is charged by a charging current by the external synchronizing signal S2 in addition to a charging current from a sawtooth wave generating circuit OC. In this case, the voltage across the capacitor Ct is charged at a large charging speed as shown in the time interval between t1 and t2 as shown in figure. Then the time when the voltage across the capacitor Ct reaches a reference voltage Vref is a time t3. Thus, the time when an output of the sawtooth wave generating circuit OC is reset is quickened by t4-t3 and the output period of the sawtooth wave generating circuit OC is synchronized with the external synchronizing signal S2.
