Title: Optical amplifier device
Inventor: IWANO TADAYUKI
IPC: H04B10/29
Filed: 1995-03-14
Abstract: PURPOSE: To provide an optical amplifier device capable of controlling the light output levels of respective light signals to a specified level regardless of the number of the light signals to be amplified. CONSTITUTION: Monitor light is taken out by an optical branching circuit 12 out of the multiplexed light signals amplified by an optical direct amplifier 11 and only the light of the specific wavelength is extracted from the monitor light by a wavelength variable optical filter 13. The gain control of the optical direct amplifier 11 is executed by the level of the extracted light signal. At this time, the transmission wavelength range of the wavelength variable optical filter 13 is previously slightly fluctuated by an oscillator 17, by which the detection of a distance between the transmission wavelength range and the wavelength of the light signal is made possible based on the component generated in the output of an onto-electric conversion circuit 14 in accordance with th fluctuation thereof.  An optical filter control circuit 16 is made to control the central wavelength of the transmission wavelength range of the wavelength variable filter 13 in such a manner that this distance value is made zero.

Title: Creep preventing device for car
Inventor: NISHIKAWA MASAO
IPC: B60K23/02
Filed: 1982-04-01
Abstract: PURPOSE:To improve departure responsibility by keeping the interior of a departure clutch of a stopping car under low pressure to prevent generation of an air bubble. CONSTITUTION:When a car stops in the state of idling, and a shift lever is located at a D-position, an oil pressure control mechanism 44 is about to supply fluid pressure to a clutch C1. In this condition, a solenoid is excited and a movable iron core 72 is lifted, which results in that there is little pressure in a spring chamber 65. Therefore, a spool 61 is pushed up by oil pressure at the lower end surface thereof so as to open a port 78. As the opening area of the port 78 is gradually ncreased with the lifting motion of the spool 61, the spool 61 stops lifting when oil pressure working upon the lower end surface of the spool 61, that is, pressure of the clutch C1 is kept at a set pressure determined by the strength of a spring 64. The set pressure at this time is set at such a low pressure that the clutch C1 is not engaged.

Title: Arc track forming method for servomechanism
Inventor: NAKAJIMA TATSUYA
IPC: B23K9/12
Filed: 1985-03-20
Abstract: PURPOSE:To shorten the arithmetic time for track formation by adding the acceleration with combination of an acceleration linear track produced by a secondary polynomial related to time and an equispeed arc track. CONSTITUTION:The time 2ta needed for acceleration is set together with a position A<+> on an arc track that is secured after a linear shift ta given from a position A at a given fixed linear speed. Then the coordinates of a middle position Pi between both positions A and A<+> is decided by a secondary polynomial related to time. This operation is simple compared with the formation of an arc track and can be performed in a short time. Then a position C<-> is set on the arc track by giving a linear shift ta from a position C at a given fixed linear speed. Here the middle position Pi between both positions A<+> and C<-> is decided from an equispeed arc track. In such a way, the arithmetic quantity is reduced for each sampling time. Thus a track is formed in a short time. Then the coordinates of the middle position Pi between positions C and C<-> is decided in the same way as that between positions A and A<+>.

Title: Bearing
Inventor: SHIOTANI YUUJI
IPC: F16C23/04
Filed: 1981-04-13
Abstract: PURPOSE:To detect the quantity of wear and prevent play, by providing tapered surfaces on the rotary shaft sleeve and other member of a bearing for the stirring unit of a chemical equipment or the like so that the tapered surfaces are put in sliding contact with each other and by energizing one of the sleeve and the member in the sliding direction to enable it to move and by finding out the quantity of the movement. CONSTITUTION:Since a bearing member 15 is energized upward by a compressed spring 18, the bearing member moves upward due to the wear of sliding contact surfaces 15a, 12a so that the sliding surface 15a is pushed on the tapered surface 12a of a sleeve 12. Play is thus prevented from occurring between the tapered surfaces 15a, 12a. The thermal expansion and contraction of a rotary shaft 11 is absorbed by the spring 18. When the bearing member 15 has moved upward, a gap is made between the tip 33b of the screw shaft 33 of a wear detector 32 and the recess 15c of the bearing member 15. At that time, a wheel 35 is rotated to bring the tip 33b and the recess 15c into contact with each other and the value indicated by a pointer 39 is read to find out the quantity of the wear. According to this constitution, the wear play prevention and wear quantity detection are enabled.
