Patent JP-H07263170-A (JP)
Title: Stroboscope
Inventor: MATSUNAGA SUSUMU
IPC: H05B41/34
Filed: 1994-03-24
Abstract: PURPOSE:To make the brightness of a strobolamp uniform from low speed to high speed by adjusting it, according to the cycle of light emission. CONSTITUTION:A strobolamp 2 is started by timing pulses the cycle of which becomes shorter the higher the speed of the object of measurement becomes. A current pulse interrupting circuit 8 interrupts the lamp current of a strobolamp when the voltage of the capacitor 7 in the middle of the light emission drops to a preset threshold. By this constitution, both the light emission starting voltage of the lamp and the light emission finishing voltage are decided accurately, so the strobolamp can be lit without the brightness fluctuating.

Title: Dynamic pressure fluid bearing
Inventor: YAMADA TAKASHI
IPC: G11B19/20
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To improve the durability and suppress the run-out of a rotary shaft. SOLUTION: Herringbone grooves 111 are cut in the lower part of the outer peripheral surface of a rotary shaft 106. Plural notches 11 are formed on the outer periphery of a rotary thrust plate 10 in which the rotary shaft 106 is fitted and fixed. Lubricating fluid is sealed between the rotary shaft 106 and the rotary thrust plate 10, and bearing surfaces 113 or the inside surface of a shaft hole. When the rotary shaft 106 and the rotary thrust plate 10 are rotated, pressure is generated by the herringbone grooves 111 to support radial load. Further, pressure is generated by the notches 11 in the neighborhood of the outer periphery of the rotary thrust plate 10 to receive thrust load. Furthermore, since the lubricating fluid is efficiently circulated by the notches 11, the frictional loss is reduced to enhance the durability, and thus to suppress the rotational run-out.

Title: Downtake of distillation column
Inventor: JIEEMUZU OO NIII
IPC: B01D3/32
Filed: 1993-04-21
Abstract: PURPOSE: To provide a downcomer for a distillation column which prevents upwardly flowing vapor from entering the downcomer even when an abnormality occurs in the distillation column by providing an arcuate bend at the lower edge part of an apron of the downcomer. CONSTITUTION: A liq. in the downcomer 10 is passed through a gap 22A between the tip end 8 of the apron 14 above a perforated plate 18 and a seal pan 16, and reaches a tray 24. The apron 14 is provided with an arcuate bend 8 extending along a radius R centered in the downcomer 10 at an angle of approximately 60 deg. to 120 deg.. The length R of the radius and the angle β of a curved line determine the gap 22A which remains after the bend 8 is formed. The gap 22A not only does not permit the vapor to enter the downcomer 10 but also shows the pressure drop same as or lower than the pressure drop at the time when the vapor is passed through the gap 22A between the apron 14 and the seal pan 16 of the downcomer, as compared with a linearly bent bend, as the shape of the bend 8 is substantially arcuate.  The smaller the gap 22A, the higher the downcomer 10, thereby bringing about a unit having more flexibility.

Title: Optical information recorder
Inventor: SHIMOO SHIGERU
IPC: G11B7/125
Filed: 1989-04-14
Abstract: PURPOSE:To record and reproduce information in accurate timing by making the intensity of laser light at the rise part of a laser light pulse higher than at a following part and making the intensity of the laser light immediately after the fall of the pulse lower than the intensity of stationary wave. CONSTITUTION:The output pulse of a buffer amplifier 104 is differentiated by a differentiation circuit consisting of a capacitor 25 and a resistance 26. Therefore, a small positive pulse is inputted in a transistor TR 24 at the rise of a recording signal 101 and a small negative pulse is inputted there at the fall of the recording signal 101. Therefore, a bias current from the TR 24 is changed so that the intensity of irradiation to a recording medium 11 may be increased at a leading edge part which is irradiated with recording light and the intensity of the irradiating light may be decreased immediately after completing the irradiation of the recording light. Thus, the shortage of the rise of a temperature at the leading edge of a bit is compensated and trailing at the trailing edge part of the bit is eliminated, so that the bit having the accurate timing is formed at the leading edge part and the trailing edge part.
