Title: Signal processing circuit for distance measuring device
Inventor: NISHIRA HIROTAKA
IPC: G01B11/02
Filed: 1983-04-25
Abstract: PURPOSE:To obtain a characteristic having a good signal to noise ratio S/N with a low voltage power source by operating linearly amplifiers irrespectively of the distance and reflectivity of a target object (subject). CONSTITUTION:If the distance from a target object (subject) 3 which is an object to be measured is a middle distance and the reflectivity of the subject is about ''middle'', that is, if the quantity of incident light is about ''middle'', the output of a level decision circuit 12 attains a high level ''H'' so as to output a signal at a distance measuring timing t1 where the voltage value VD set by the output level decision circuit 12 of a gain variable amplifier 9b is attained. Said output is fed to a waveform processing circuit 11 which creates distance measuring information. Namely, the quantity of incident light is amplified linearly to the voltage value VD of the adequate level at which the dynamic range of the circuit can be fully assured, by the gain variable amplifiers 9a, 9b. The signal for the distance measuring timing is thus read.

Title: Wide-band optical transmission system
Inventor: YAMAGUCHI HIDEO
IPC: H04B10/29
Filed: 1983-04-27
Abstract: PURPOSE:To eliminate deterioration in transmission characteristics due to reflection and to perform multidrop transmission by coupling a laser diode with plural optical fibers so that remote distances from the laser light emission surface to end surfaces are short enough to ignore the influence of reflection. CONSTITUTION:Analog modulation is imposed upon the laser diode 2 by a signal generated by amplifying 1 a multiplex video signal. The light emission surface of the diode 2 and end surfaces of optical fibers 3a-3c are set at such a remote distance that the influence of reflection is ignored, and the diode 2 is coupled with the fibers 3a-3c. Light signals from the diode 2 transmitted by the fibers 3a-3c are converted by photodiodes 5a-5c into electric signals, which are amplified to 6a-6c. Analog modulation is imposed upon a laser diode 7 by a signal generated by the amplification 6b to reconvert into a light signal, which is transmitted by coupling the diode 7 with optical fibers 3d-3f at similar remote distances. Consequently, a reflected wave from an optical fiber end surface or in a transmission line less enters the laser diode again to prevent deterioration in transmission characteristics.

Filed: 1990-03-23
Abstract: PURPOSE:To improve commodity value and quality without generating burrs by restraining a height from the upper surface of a lower die and the width of a top part respectively in the specific range over the whole periphery of a blanking hole of the lower die and providing a projection where an angle between the inner peripheral surface and the outer peripheral surface lies in a specific range. CONSTITUTION:A lead frame is blanked by progressive dies having upper and lower dies 5, 8 between which a metallic or alloy material is put and through which a blanking hole is formed and a punch 6. The lower die is used which is provided with a projection 16 where a height from the upper surface of this lower die is 50-100mum over the whole periphery of the blanking hole of the lower die 8, the width of the top part is 50-200mum and the inner peripheral surface of an extended surface of the blanking hole of the lower die and the outer surface of the projection make an angle 10-30 degrees. Consequently, burrs are not pushed to the outer surface of the lead frame but can be sealed inside and this effect is remarkable especially in a material high in viscosity and in a material poor in blankability. As a result, commodity value and quality can be improved and a carrier trouble in a mounting stage and a mounting trouble can be restrained.

Abstract: PURPOSE:To decrease the oscillation of a target by increasing the rigidity of a rotor- supporting part by supprting a rotor, one end of which is fixed to the target, by a fixed shaft through a bearing so that the rotor can be rotated by a revolving magnetic field applied from the outer side of the rotor, and integrating a part of the bearing with the fixed shaft. CONSTITUTION:A bearing inner race corresponding to a bearing outer race 20 is integrated with a fixed shaft 21. A track groove for bearing balls 22 are provided on the fixed shaft 21. Besides, one side of the inner diameter of the outer race 20 is cut up to the diameter of the track groove so as to make a so-called bearing of the angular contact type, thereby constituting a complete ball bearing which has no members supporting the bearing balls 22. In addition, a slide 23 and a bearing inner race 24 are attached around the fixed shaft 21 in such a manner that the slide 23 and the inner race 24 can be freely slidden in the axial direction, and preliminary pressure is applied to the slide 23 and the inner race 24 by means of a preliminary pressure spring 25. Therefore, the bearing balls 22 can be assembled as an insertion bearing inside the outer race 20 after the outer race 20 is inserted from the left side of the fixed shaft 21. By making a rotary anode for an X-ray tube to have such a structure as mentioned above, the deflection of the supprting system can be decreased by increasing its ridigity.

Abstract: PROBLEM TO BE SOLVED: To provide an aligner and a resist aligner capable of focusing a mask image on a wafer by using deep UV zone (200 to 300 nm wavelength) and leaving no tapered resist after the development. SOLUTION: Light of 200 to 300 nm wavelength emitted from a UV lamp 2 is condensed by an elliptical condenser 1, incident over a reflection optical system composed by a lens 11 and a reflecting optical device 12 through a flat reflector 3, a shutter Sh, an optical fiber 4, and a mask M, and irradiates the exposure surface of the wafer W. The direction of an edge e1 of a shade S1 of the mask M is the radial direction of the optical axis and the edge e1 is disposed on the sagittal conjugate face. The direction of an edge e2 of a shade S2 is the circumference direction of an optical axis and the edge e2 is disposed on tangential conjugate face. Thus the structure makes it possible to eliminate an astigmatism caused by the optical system above and to sharply focus the mask image on the wafer W.

Abstract: PURPOSE: To automatically take the rotary balance of an inner basket regardless of the magnitude of initial eccentricity to smooth rotation by providing a connection means enabling the lateral movement of the inner basket and absorbing the inertial movement with an outer basket. CONSTITUTION: For example, when an article desired to be dehydrated is placed in an inner basket 1 in an eccentric state and an outer basket 3 is rotationally driven by a motor 12, centrifugal force in an eccentric direction is generated in the inner basket 1 rotated along with the outer basket 3. Chambers 2 in the eccentric direction are compressed by this centrifugal force and vibration is generated in the outer basket 3. When this vibration is detected by a vibration sensor 6 and amplified to turn a contact ON, all of communication pipes 4 are opened and a fluid from the compressed chamber 2 is transferred to the other chamber 2 to set off centrifugal force. Perfectly set-off vibration is stopped, and the output of the vibration sensor 6 is eliminated the contact is turned OFF and the movement of the fluid in the respective chambers 2 is stopped, and then smooth rotation is performed.
