Abstract: PURPOSE:To reduce the lamination errors between projected images by a method wherein the error amounts due to the distortion of a pattern formation lens and a TTL alignment lens are stored to correct the results in alignment conforming to the stored error amounts and then a pattern is projected on a wafer. CONSTITUTION:The error amounts between an alignment mark on an ideal lattice image 3a and another alignment mark on a projection image 3b are measured at respective points in an image field to make up a map and further to be stored into a memory 10 and then both images 3a, 3b are aligned with each other using motors 1m, 1n. Resultantly, the lamination errors of DELTAX1+DELTAX2 are made.

Title: Voice coding device and voice decoding device
Inventor: HOTTA ATSUSHI
IPC: G10L19/038
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To improve the transmission characteristic by providing an audible sense weighting filter and a reflection coefficient discrimination means so as to use the filter when the reflection coefficient is at the outside of a specified range and not using the filter when the reflection coefficient is within the specified range. SOLUTION: A reflection coefficient discrimination section 17 receiving a reflection coefficient calculated by an audible sense weighting filter adaptive device 7 provides an output of '1' when the reflection coefficient is within a specified range and provides an output of '0' when the reflection coefficient is at the outside of the range so as to allow usual filter operation. A switch control section A18 monitors a signal on a signal line 101 and sends a control signal with a content of denoting that a switch 19 selects a signal not passing through an audible sense weighting filter 8 to a signal line 102 when the signal is '1' and sends the control signal with a content of denoting that the switch 19 selects a signal passing through the audible sense weighting filter 8 to the signal line 102 when the signal is '0'. The switch 19 selects any signal under this control.  Thus, even in the case of reception of a DTMF signal not a voice signal, production of distortion is prevented.

Title: Focus plate
Inventor: TOKUHARA MICHIHIRO
IPC: G02B5/02
Filed: 1978-11-22
Abstract: PURPOSE: To make finder brighter and inexpensively obtain the device of small out-of-focus amount by bundling a plurality of optical fibers to part of a focus plate to an optical fiber part and performing focusing with this.  
     CONSTITUTION: The subject image is formed on a film 3 by an objective lens 1 and relay lens 2 and part of light is passed through a lens 5 by a photo splitter 4, by which the subject image is formed on a focus plate 6. It is observed by the eye 12 through a field lens 8, elector lens 9, field lens 10 and eyepiece 11. The focus plate 6 has an optical fiber bundle part 15 at the center of a transparent substrate 14 such as of glass plate or acrylic plate. The quantity of transmitted light is increased by the transparent plate 14, by which the bright finder is provided. Since the area of the costly optical fiber bundle is small, the cost becomes relatively low and in addition the transparent plate does not undergo ground glass action and threfore it offers an advantage of difficulty in noticing the distortion of the image owing to the curvature of field.

Abstract: PURPOSE: To obtain a simple-structure and high-stability FM signal generation circuit by giving the A/D conversion to the analog signal and then delivering the signal of the frequency according to the division number which is memorized previously in the ROM via the output of the A/D-converted analog signal.  
     CONSTITUTION: The input aural signal supplied from the amplitude detection circuit of the lincompex communication equipment is supplied to the address of ROM32 after the amplitude component is converted into the digital signal through A/D converter 31. The signal equivalent to the address and read out from ROM32 is supplied to variable divider 32 to control the division number and then the output frequency of oscillator 34. Oscillator 34 uses the fixed oscillator featuring a high stability such as the crystal oscillator or the like, and the address of ROM32 is proportional to the mean electric power of the input aural signal. And the division number corresponding to the input mean power is calculated and written previously into the ROM. In such way, an economical and high-stability FM signal generation circuit can be obtained with a simple constitution.

Title: Plunger solenoid driving circuit
Inventor: NANJIYOU RIYUUICHI
IPC: H01H47/04
Filed: 1978-11-24
Abstract: PURPOSE: To provide a common power source for the solenoid driving and its driving circuit by inserting between the power source and the plunger solenoid a switching means which consists of a part of the driving circuit.  
     CONSTITUTION: Applying a high voltage level driving signal to the terminal S 1  allows the transistor TrQ 1  to be conducted to charge the capacitor C 1  and TrQ 2  to be non-conductive. The signal application to the terminal S 1  also caused the TrQ 6  and TrQ 7  to be conductive. And the TrQ 2  non-conductance produces TrQ 4  conductance. As a result, the power source +B voltage drives the plunger solenoid PL 1  through TrQ 4 , Q 7 . As the capacitor is charged. TrQ 2  conducts and TrQ 4  non- conducts. Since the base of TrQ 5  receives the voltage controlled by the Zener diode ZD 1 , TrQ 7  conductance causes TrQ 5  conductance. Accordingly, the signal application to the terminal S 1  causes TrQ 4 , Q 5  conductance thereby applying a starting voltage to the solenoid PL 1  and after a given time, TrQ 4  becomes non-conductive to allow a holding voltage application.

Abstract: PURPOSE: To improve thermal efficiency, by providing a fuel combustor at a part of a rotary member.  
     CONSTITUTION: A gas turbine comprises an impeller A, a main pipe for supplying fuel and a casing. When the impeller A is rotated by an appropriate method, air is sucked from a port near the center of a passage 7 and accelerated by the impeller 4 of a centrifugal compressor because the impeller A has the same construction as the impeller 4. The air is supplied from a compression section 8 to a combustion chamber 9 while the air is compressed by centrifugal force. The air is then ejected from a nozzle 10 in a circumferential direction opposite to the direction of the rotation. The fuel is burned in the combustion chamber 9 to heat the compressed air to eject it from the nozzle 10 at a speed higher than the circumferential velocity of the impeller A. The impeller A is caused to start self-rotation by the reaction of the ejected air.

Abstract: PURPOSE:To prevent microorganisms such as bacteria from generating and breeding by providing an ultraviolet ray germicidal lamp in parallel with an adjacent position to a brush to irradiate the brush with ultraviolet ray from the lamp. CONSTITUTION:An ultraviolet ray germicidal lamp 21 is so mounted between supporting plates 6 and 6 that its longitudinal direction becomes parallel to the axial direction of a brush 7. Accordingly, when the lamp 21 is fired, an ultraviolet ray passes gaps of the bristles 7a of the brush 7 to irradiate the inserted part of the bristles 7a. When the brush 7 is rotated to clean a wafer 1, the ray is radiated to the whole brush 7. The lamp 21 is not necessarily fired continuously, but when it is intermittently fired for a firing time capable of preventing a microorganism such as bacteria from generating, its cost can be suppressed to low value.
