Patent JP-S63273018-A (JP)
Title: Presence-in-room sensor
Inventor: ONO YOSHIHIRO
IPC: G01J1/02
Filed: 1987-04-30
Abstract: PURPOSE:To obtain a small size and low-priced sensor of sure operation by constituting the sensor by combining a photoelectric transducer, an amplifier, a differentiating circuit, a detecting circuit, a signal delay circuit, a binary- coding circuit and the like together. CONSTITUTION:A photocurrent from a silicon photodiode mounted to a ceiling is amplified by an operational amplifier 2 and outputted as a voltage. In an output signal thus obtained, a low frequency AC component due to the movement of a human in field of view is superposed on a DC component due to a mean luminance. A differentiating circuit composed of C1 and R2 removes the DC component and takes out the AC component to output it. An operational amplifier 3 amplifies the AC component. A diode D1 half-wave-rectifies an output from the amplifier 3 and outputs a resultant pulsating current. A capacitor C2 is charged at the rising of the output pulse of the diode D1 and, at the falling thereof, discharged according to the time constants of a resistor R5 and the capacitor C2. When the output of a time constant circuit takes a prescribed value or above, the collector current of a transistor Tr1 flows to drive a relay 4. The relay 4 turns on and off an illumination in accordance with the output of a binary-coding circuit (Tr1 and a resistor R6).

Filed: 1982-06-23
Abstract: PURPOSE:To accurately locate a pattern on a wafer without a fear of causing a flaw by presetting the reference surface of wafer for positioning and providing a non-contact type distance detector at the area isolated from such reference surface. CONSTITUTION:A wafer for calibration is placed on a table 3 and the table 3 is shifted to the right and left and also vertically. Thereby, the area of calibration wafer opposing to the non-contact type distance detector 14 is caused to match the reference surface A. At this time, a detecting output is stored in a controller 15. Next, a wafer 1 to be processed is placed on the table 3, a pulse motor 11 is operated by the controller 15. Thereby, a support table 4 is driven vertically and the motor 11 is caused to stop at the point where an output of detector matches the stored detection output. Thereby, the wafer 1 accurately matches the reference surface A. In above operations, since the wafer 1 does not caused to be in contact with the detector 14, it does not receive any damage due to contactness.

Abstract: PURPOSE:To perform a relay operation with simple constitution by a method wherein a signal input of an adder is interrupted, and a controlling signal is applied to a register that stores the added results, an output of the adder and a controlled signal multiplied, and the result is made to be the relay operation output. CONSTITUTION:In a digital differential analyzer DDA, selectors SL5-SL7 and a selector SL8 that by-passes an operator OP are prepared at inputs of Y registers RY of the second and the third adders AD2, AD3 and for accumulation of the added results respectively, and are controlled with a mode signal from a mode memory MM. Further the operation is made by taking the AD3 as a multiplier and an output circuit OZ as a gate circuit being on state in mode signals. Since an input of one side of the AD is interupted, contents of the RY are inputted to the AD3 as they are  and multiplied by a controlled signal DELTAX from a DELTAZ memory MZ4, and are outputted as the operated result DELTAZ. An analog controlling signal Sc is subjected to an  A/D conversion and is given to a YR, and a signal DELTAX is, as it is, or as the whole  bit O, outputted from the circuit OZ, thereby allowing the signal DELTAX to perform the  same operation as it is subjected to a switching action.

Title: Optical fiber for maintaining plane of polarization
Inventor: KATSUYAMA TOSHIO
IPC: G02B6/02
Filed: 1985-05-22
Abstract: PURPOSE:To obtain an optical fiber characterized by low transmission loss and high maintaining efficiency for the plane of polarization by constituting the optical fiber of a circular core, a peripheral elliptic jacket and a supporting part and setting up the distribution of refractive indexes properly. CONSTITUTION:The optical fiber is constituted of the circular core 1, a circular clad 2 formed concentrically with the core 1, the elliptic jacket 3 formed on the periphery of the clad 2, and the supporting part 4. The refractive index of only the core 1 is set up to a high level and the ones of other parts are set up to almost similar levels. Therefore, the whole optical energy is concentrated into the core 1, the refractive indexes of an optical transmission part in the optical axis directions rectangularly intersected with each other are made different due to distortional stress by the jacket 3, so that double refraction is generated, a phase transmission constant difference is increased and the optical fiber having high maintaining efficiency for the plane of polarization can be obtained. The jacket occupying the most part of the area is extremely reduced at its optical energy distribution and the transmission loss can be reduced.

Title: Electrophotographic copying method
Inventor: SAKAMOTO KOUJI
IPC: G03G21/00
Filed: 1979-08-25
Abstract: PURPOSE: To prolong the life of a photoreceptor which has been discarded as the  one having terminated of its life, by leaving the photoreceptor in the dark thereby  making it recover from fatigue.  
     CONSTITUTION: A drumlike photoreceptor 1 is formed by the 1st segment (a) and the 2nd segment (b). When the performance of the 1st segment (a) has lowered owing to its reiterative use, the photoreceptor 1 is rotated in excess by 180° to put the 2nd segment 1b in a ready to use state. Since it turns out that during the use of the 2nd segment 1b the 1st segment 1a is left in the dark, it recovers from fatigue. When the performance of the 2nd segment has lowered, again the 1st segment 1a is put in a ready to use state in a similar manner. Thereafter, this is repeated. With such constitution, the life of the photoreceptor may be prolonged considerably.

Filed: 1993-05-10
Abstract: PURPOSE:To unnecessitate the mounting adjustment of an objective lens and to provide an optical pickup device having a means for compensating the aberration generated by the tilt of the objective lens by arranging a parallel plane plate for compensating coma aberration between a light source and a collimator lens and adjusting an angle between the perpendicular direction of the parallel plane plate and an optical axis.

The collimator lens 2 changes the incident laser beam to a parallel light beam and introduces it to the objective lens 3.A light spot 9 in which coma aberration is compensated is formed on an information recording medium 4 by means of the objective lens 3. The adjustment of the tilt of the objective lens 3 at the time of assembling generated in the manufacturing process is unnecessary and this tilt is easily adjusted by adjusting the tilt of the parallel plane plate 5 for compensating the coma aberration even when the coma aberration generates.

Abstract: PURPOSE:To always efficiently produce single faced corrugated cardboard at a high speed by certainly molding corrugated cardboard by rotating a plurality of upper stage rolls at a high speed even when core base paper is thin or thick only by changing the use numbers of the rolls. CONSTITUTION:When core base paper 1 is thick, respective upper stage rolls 11, 12 are meshed with a middle stage roll 10. The first corrugating molding of the core base paper 1 is performed by the meshing of the upstream upper stage roll 11 with the middle stage roll 10 and the second corrugating molding thereof is performed by the meshing of the downstream upper stage roll 12 with the middle stage roll 10. By performing corrugating molding two or more times, certain corrugating molding can be performed while a high molding speed is kept.

Corrugating molding can be applied to the core base paper 1 by the meshing of the upper stage roll 1 and the middle stage roll 10. Because of the thin core base paper, high speed corrugating molding can be performed.
