Title: Optical cable switch
Inventor: IMAI MICHITAKA
IPC: G02B26/08
Filed: 1990-09-10
Abstract: PURPOSE:To offer the switch which switches plural optical fibers in batch units by rotating the terminal surfaces of the optical fibers and the terminal surfaces of optical paths relatively on their circular tracks and switching the optical paths. CONSTITUTION:An optical path switching part 30 has coaxial and mutually adjacent cylinders 31 and 32. Terminal parts 20-23 of respective cables 10-13 are inserted at positions determined by dividing the outside cylinder 31 equally into four in the circumferential direction and the respective terminal surfaces are exposed in the internal surface. Terminal parts 50-57 are inserted at positions determined by dividing the inside cylinder 32 equally into eight in the circumferential direction and the terminal surfaces of the respective terminal parts 50-57 can face the terminal surfaces of the respective terminal parts 20-23 of the optical cables 10-13. In the state shown in a figure, the inside cylinder 32 is rotated anticlockwise by 45 deg. through, for example, a driving part to couple the optical cable 10 with the optical cable 13 through an optical path 43 and the optical cable 11 with the optical cable 12 through an optical path 42. Thus, optional two of the four optical cables can be coupled with each other and the switching in optical cable units becomes possible.

Title: Target value follow-up quick responsive 2-freedom degree adjuster
Inventor: HIROI KAZUO
IPC: G05B11/42
Filed: 1990-09-07
Abstract: PURPOSE:To shorten the response time by fetching directly the control target value with a signal switching means when the arithmetic target value is approximate to the control target value for PI (proportion/integration) adjustment. CONSTITUTION:A switching command is received when a comparison/judgement means 11 decide a difference larger than a prescribed level. Then the arithmetic target value SV0 is selected. Meanwhile the control target value SV is selected at the reception of a switching command with the difference higher than the prescribed level. Then the value SV is sent to a deviation computing means 3. That is, a switching command is produced when the difference is larger than a prescribed level delta. Therefore a signal switching means 12 selects the value SV after the reception of the switching command. Thus the target value for PI adjustment is defined as SVa = SV. Consequently, the response speed is set at the value SV in a short time.

Title: Fixed magnetic disk device
Inventor: IMAI HIROSHI
IPC: G11B33/14
Filed: 1985-10-24
Abstract: PURPOSE:To obtain a fixed magnetic disk device containing a compact air filter having high efficiency by leading the air current produced by the revolution of a magnetic recording disk to the inflow side of the air filter and then connecting the revolving center part of the disk and the outflow side of the filter via an air duct. CONSTITUTION:An air filter device 45 is set near the outer circumference of a magnetic recording disk 2. The inflow side of the device 45 is set in the direction of an air current produced by the revolution of the disk 2. The air current increases the pressure at the inflow side of the device 45. The revolving center part of the disk 2 where the pressure is reduced by its revolution is connected to the outflow side of the device 45 via the duct 71. Thus the pressure is reduced at the outflow side of the device 45. Thus the difference in pressure is increased between the inflow and outflow sides of the device 45. This increases the flow rate of air and improves the filtering efficiency.

Title: Method of mixing four photons in optical fiber and short- pulse generator using the method
Inventor: ASO OSAMU
IPC: G02F1/35
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To generate four photons mixture(FPM), in the form of the maximum utilization of characteristics of a pump light source, by having as a periodic function an idler light conversion efficiency at the output end of an optical fiber relative to its length, with the efficiency setting the length at or below the minimum optical fiber length with the maximum value. SOLUTION: The pump light entering from a pump light source 1 is mixed with an optical signal by a light mixer 2. This mixed light generates idler light 7 in the highly nonlinear optical fiber 3 in which the idler light conversion efficiency at the output end of an optical fiber relative to its length sets the length at or below the minimum optical fiber length with the maximum value. This idler light 7 is the light to which the signal light is converted as for the wavelength through an FPM interaction. At the outgoing end of the fiber, the light 6 is emitted in which all the signal light, pump light and idler light 7 exist on the frequency axis; hence, a wavelength changer is realized by designing to take out only the idler light 7 using an optical filter 4.

Abstract: PURPOSE:To control the steering angle ratio variably in accordance to various external conditions, by moving a gear case in the direction of rack case while interlocking with rotary operation of handle and controlling the movement on the basis of external condition such as car speed. CONSTITUTION:Upon rotary operation of handle 1 in the direction A, the rack shaft 16 will move axially to move a pin 13 in perpendicular direction through inclined section 17' of the groove 17 in the rack shaft 16, thus to rotate the lever 12 around a fulcrum 14' and to move the pivot shaft 11 of said lever 12 and gear case 4 in the direction of rack shaft 16 to move the gear case 4.

As a result, the movement of gear case 4 is controlled in accordance to the external condition to produce various non-linear steering angle ratio.
