Title: Contactless communication with rotary apparatus; propeller de-icing
Inventor: SMITH JAMES ANDREW TIMOTHY
IPC: B64D15/12
Filed: 1994-09-02
Abstract: A rotor carries at least one electrically powered device 3 and switching means 4 which controls the supply of power to the device 3 in response to a control signal supplied via a contactless communication link between a fixed structure and the rotor. An inductive, optical or radio frequency link may be used, and the system may be used with sensors or actuators on a vehicle wheel, or to control excitation of generator windings, or for aircraft propeller pitch control. More particularly, the devices 3 are electro-expulsive or impulsive devices for removing ice from aircraft propellers, or especially de-icing or anti-icing heaters. The heaters 3 are powered by a three-phase main winding 7 on the rotor which also carries auxiliary windings 8, 9 providing power to the operating circuits of switches 4 which energise the heaters 3 sequentially in response to control signals from an airframe mounted computer 12. Windings 7, 8, 9 form a generator 5 in cooperation with stationary permanent magnets 6. Control signals are applied to a winding 13 to modulate the field of magnets 6, so that the outputs of the auxiliary windings 8, 9 are modulated with the control signals. Each of the switching units 4 may be addressed individually. The same or a similar contactless communication link may be used to transmit signals indicating sensed heater current and voltage from the switching units 4 to the computer 12 which may vary the on-off times of the switching units to vary heater power. <IMAGE>

Title: Light ozone asher, light ashing method, and manufacturing method of semiconductor device which avoids UV radiation of sample surface
Inventor: SEIWA YOSHITO
IPC: H01L21/3065
Filed: 1995-02-21
Abstract: A light ozone asher (101) comprises a process chamber (220) having a sample stage (225), in which a surface of a sample (1) put on the stage (225) is processed by active oxygen generated by irradiating ozone (from inlet pipes (111a) and (111b)) with UV rays in the process chamber, and is characterised by means for applying UV rays (101a, 101b) such that the surface of the sample (1) put on the sample stage (225) is not irradiated with UV rays. Since the sample surface in the process chamber is not irradiated with the UV rays when an organic substance on the sample surface is removed by active oxygen, the organic substance (scum, 11c) left at an organic-substance-removed-part in the patterned organic substance film can be removed without destroying the pattern of the organic substance film. Irradiation of the sample surface with UV rays can be avoided by the positioning of UV lamps which emit in a vertical direction only (Figures 1, 6, 7 and 9), shielding or partitioning plates (121 and 122, Figures 2 and 3; 131 and 132, Figure 4; and Figure 10), shielding coating (141, Figure 5) or the use of a shielded sample holder (Figure 8). The sample stage may be heated or cooled. <IMAGE>

Title: Fabrication of micro-motor
Inventor: MCCARTHY SHAUN LEAF
IPC: H02K37/12
Filed: 1995-06-26
Abstract: A method of fabricating a planar micro-motor particularly well-suited to batch methods of microfabricating multiple planar stepper micro-motors from a single substrate wafer. Such micro-motors, having a planar stator supported by an electrically insulating substrate, a planar rotor body aligned over the stator, and a housing integral with the substrate and forming a rotor chamber therewith in which the rotor is rotatably captured, are formed by microfabricating the stator, rotor, and housing on the substrate with a boundary of release material encapsulating the rotor body. The release material is then removed to free the rotor body for rotation within the rotor chamber. Release materials, such as poly-alpha-methylstyrene, are suitable, being removable to free the rotor by heating to at least 180 DEG  C. under vacuum. In the course of the sequential processing steps during the microfabrication, multiple layers of photo-responsive patterning material are used, some of which layers are removed in their entirety, while portions of at least some of the layers of photo-responsive patterning material remain in the micro-motor to at least partially form the housing or as part of the rotor body.

Title: Optical spectrum measuring apparatus
Inventor: IWASAKI TAKASHI
IPC: G01J3/28
Filed: 1995-09-12
Abstract: In a high speed optical spectrum measuring apparatus, an encoder 14 is connected to the axis of a unirotational, continuously rotating, motor 10. A counter 15 counts the number of pulses outputted from the encoder 14. A comparator 17 compares the value stored in a counter 15 with the value stored in a register 16, set by a control section 12, and outputs an AD conversion signal when the values are equal, causing the light intensity for that particular angle to be transferred, via an AD convertor 9, to the control section. Upon receiving the AD signal, the control section then sets the register with the next value for which a reading is to be taken, thereby, eventually, scanning the entire spectrum. A further embodiment includes the use of a delay circuit for use when the required sampling period does not correspond to a whole multiple of encoder pulses. <IMAGE>

Patent GB-966303-A (GB)
Abstract: 966,303. Retarding devices for shoots. E. KOSTER. Nov. 21, 1960 [Nov. 26, 1959; Jan. 22, 1960], No. 39987/60. Heading B5S. Material falling down shoot 1 is retarded by a series of steps 100. Each step has two portions, a fixed portion 4 and an adjustable portion 3, and each portion 3 has an arm 5 provided with a pin 7 which engages in slot 34 formed in carriage 26. Carriage 26 runs on wheels 29 and 30 along a rail disposed on the side of the shoot, and is progressed upwards or downwards by means of a vertical rope (not shown). When the carriage moves upwards, pin 7 is urged rightwards, and step portion 3 is withdrawn progressively from the shoot in the same direction. Step portion 3 thus moves horizontally backwards and forwards whilst supported between rollers 8 and 9. If roller 8 is removed, the effect of pin 7 moving in groove 34 is to withdraw step portion 3 sideways and at the same time to cause it to take an inclined position. Step portion 3 is normally held in a fixed position by a bar 40, pin 41 of which engages in the holes shown in bar 5. Carriage 26 may be provided with a wedge by which pin 41 may be automatically disengaged so as to permit the step portion 3 to be withdrawn. Second embodiment -The wheels of carriage 26 are omitted and the carriage is adjustably boltable to rails positioned on the side of the shoot. In a third embodiment, the adjustment is effected by a cam carried and operated by a rope, the cam releasing a spring-biased retaining pin to permit the shoot to change its inclination by falling under gravity. The inclination of groove 34 is adjustable at 39.
