Title: Optical displacement detector
Inventor: TAKAGI MASAAKI
IPC: G01D5/38
Filed: 1989-09-21
Abstract: PURPOSE:To image a spot with narrow peak width and to detect the reference position of an encoder plate with high accuracy by forming a holographic lens on the surface of a moving member adjacently to a diffraction grating. CONSTITUTION:On the surface of the mobile member 2, the holographic lens 10 is formed adjacently radially inside a diffraction grating 3. The lens 10 is arranged in the effective sectional area of luminous flux which is projected from a spot light source 1 and converges incident light every time the lens 10 crosses the optical path to form the spot which has extremely sharp peak width at a specific front distance. Another fixed slit 8 is arranged at the image formation position of this spot. A slit which has opening size corresponding to the spot diameter is formed in the fixed slit 8. A photodetector 9 is arranged nearby in front of the fixed slit 8 and detects light transmitted through the fixed slit 8 to output a corresponding electric signal. Consequently, the reference position of the encoder plate can be detected with accuracy nearly equal to or higher than the resolution of the diffraction grating 3.

Title: Waveform equalization circuit
Inventor: HAMURA YOSHIHIRO
IPC: G11B5/09
Filed: 1990-09-17
Abstract: PURPOSE:To cancel the pseudo signal of a straight polarity and to improve a read margin by delaying an input signal waveform by prescribed time, attenuating it in a prescribed level and synthesizing it. CONSTITUTION:The signal waveform having the pseudo signal of the straight polarity is inputted to a delay circuit 17 and an operational amplifier 19 from an amplifier circuit 14. The circuit 17 delays the signal waveform for previously decided time and transmits it to a variable attenuation circuit 18. The terminates the circuit 17 by the charactersitic impedance of the circuit 17 and the signal waveform transmitted from the circuit 17 is attenuated to the prescribed level without reflecting. The waveform whose amplitude becomes small is transmitted to the operational amplifier 19. Since the amplifier 19 subtracts the signal waveform from the circuit 14 and the waveform from the circuit 18, the signal waveform where the pseudo signal is cancelled is transmitted to the output-side of the amplifier 19. Thus, noise at the time of reproducing data is reduced and the read margin can be improved.

Title: Rotating machine
Inventor: OKUYAMA YOSHIHIKO
IPC: H02K3/34
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To secure appropriate insulation strength by taking into consideration the impression of a surge voltage and to reduce the increase in size of a rotating machine. SOLUTION: The number of windings of a coil 2, from which the external terminal of an electric slave winding wire is pulled out, is set to be smaller than that of other coil 3. A wire insulation 22 of a wire 21 constituting a coil 2 is made thicker than the wire insulation 32 of the coil 3, in accordance with a surge voltage which the receptive coils bear instead. Even if a surge-like voltage is applied from teh outside, and the bearing rate of first coil surge voltage in the plural coils constituting one phase of the electric slave winding wire is high, the wire insulation thickness is made thick and insulation strength between wires is reinforced. Thus, a machine can be sufficiently made proof against it.  Although only the coil of high bearing rate of serge voltage is insulation-reinforced and the number of windings is reduced instead, the rate of the number of reduced windings is small compared to the total number of windings so that the size increase of the rotating machine can be reduced.

Abstract: PURPOSE:To change a desired region in a semiconductor layer applied on an amorphous substrate or a thin-film excellently into a signle crystal by previously forming a protective film on a semiconductor thin-film layer by using a substance optically transparent to projecting laser beams. CONSTITUTION:A thremal oxide film 2 is formed on a single crystal silicon substrate 1, and a polycrystalline silicon layer 3 is further shaped on the thermal oxide film 2. An oxide film 4 is formed as a protective film as a first layer, and silicon nitride films 5 are shaped as protective films as second layers. The upper section of a region to be changed into a single crystal in the polycrystalline silicon layer 3 is removed through a photolighographic process, and the silicon nitride films 5 are removed. When such structure is irradiated by a laser, a temperature rise in a region 11 consisting of one layer of the protective film is made larger than that in regions 12 composed of two layers of the protective films because laser power reaching to the polycrystalline silicon layer 3 is larger than the region 12 in the region 11. Consequently, solidification starts from the regions 12 consisting of two layers of the protective films at a low temperature as shown in the arrows A, and gradually progresses to the resion 11 composed of one layer of the protective film Accordingly, an excellent single crystal layer is obtained in the regions 12 consisting of two layer of the protective films.

Abstract: PURPOSE:To handle any trouble mode of a station by employing a loop-back and a relay-bypass system in combination and making the loop-back system effective when bypass formation of continuous stations is detected. CONSTITUTION:If a fault originating from a break of power supply, etc., occurs to a station ST181b connected to a main system 12a and a slave station 12b, a relay coil 42 is turned off to make contacts 43a, 43d, 43e, and 43h and break contacts 43b, 43c, 43f, and 43g. At this time, adjacent STs 181 and 181c are normal, so relay coils 82ab and 82bc are turned on through feeding lines 80ab and 80bc to close contacts 83a-83d, forming a bypass. Further, a fault occurs to a ST181c as well, no electricity is supplied to a feeding line 80bc, so the bypass is not formed. At this time, a control part 21 for adjacent STs 181a and 181c detects the failure of transmission and connects the main system 12a and slave station 12b mutually through a switching device 25 to obtain loop-back constitution.

IPC: G03F1/76
Filed: 1990-09-19
Abstract: PURPOSE:To greatly improve the contrast of projected images and to improve the transfer accuracy of patterns by dividing the light generated from a light source to two beams of light and changing the optical path length until arriving at a mask, thereby putting the phases of two beams of the light into the antiphases from each other, then synthesizing the two beams of the light. CONSTITUTION:The light generated from the light source 2 is divided to two beams of the light L1,L2 and the optical path lengths until these beams arrive at the mask 14 are changed, by which the phases of the two beams of the light L1, L2 right after the passage through the different points of the mask 14 are made into the antiphases from each other; thereafter, the two beams of the light L1,L2 are synthesized and the surface of a sample 3 to be irradiated is irradiated with this light. The one light L1 transmitted through the prescribed transmission region on the mask 14 and another light L2 transmitted through another transmission region on the mask 14 weaken each other by interfering with each other in the boundary region at the points disposed in proximity on the sample 3 to be irradiated and, therefore, the contrast of the project ed images is greatly improved.
