Inventor: FUKUI KIYOUJI
IPC: G01C3/08
Filed: 1980-01-08
Abstract: PURPOSE: To obtain a highly precise optical distance sensor of simple constitution, by judging the distance to an object by the difference in photodetection quantity between two optical photodetection systems having the optical axes crossing the optical axis of a center optical projection system at different positions.  
     CONSTITUTION: Center optical system 10 is provided with projecting means 11 having light source 111, condenser lens 112, etc., optical fiber 12, and condenser lens 13 opposing to the other end of fiber 12, etc. Intersecting optical system 20 intersecting the optical axis of optical system 10 consists of photoelectric converting means 21, optical fiber 22, condenser lens 23 opposing to the other end of fiber 22, etc., and intersecting optical system 30 having a different point in intersection with the optical axis of optical system 10 is constituted similarly to optical system 20.

Title: Extracting device for movement information on picture
Inventor: INOUE IKUO
IPC: H04N7/18
Filed: 1987-01-07
Abstract: PURPOSE:To cope with a faster movement and a more sudden change of pictures while keeping a high displacement accuracy, by binarizing the input pictures. CONSTITUTION:The band width is limited down to <=1/2 sampling frequency (fs) by an LPF 100 before an input picture signal 111 is digitized. A binarization circuit 104 reads a digitized multi-gradation picture signal 115 out of a buffer memory 103 and converts it into the digitized data. A displacement candidate extracting part 107 uses a picture signal 118 of a relevant block of a relevant frame read out of a binarized data frame memory 106 according to an address control signal 117 and a picture signal 119 of the preceding frame within the maximum displacement detected previously as inputs and compares both signals with each other for each picture element against the relevant block. In such a way, the input picture signal is binarized and processed.

Title: Detector for detecting position or speed magnetically
Inventor: SAGARA TAKEHIKO
IPC: G01B7/00
Filed: 1990-01-08
Abstract: PURPOSE:To enable highly accurate position detection even if the spacing between an MR element and a magnetic medium varies by arranging plural magnetic tracks on the magnetic medium with a specific-pitch shift, and removing the distortion of an output waveform due to the saturation of the MR element which constitutes a magnetic sensor. CONSTITUTION:The magnetic medium 3 where the two magnetic tracks T1 and T2 are arrayed in parallel while shifting in pitch by lambda/6 is provided at the outer periphery of a rotary drum 1 and the magnetic sensor 4 is arranged at a small interval of spacing. The magnetic sensor 4 has four MR elements on a substrate 4 at lambda/2 pitches and detects magnetic variation of the moving magnetic medium 3 to detect the rotational position and the speed of the rotary drum 1. The phase difference between the two tracks T1 and T2 of the magnetic medium 3 is set to lambda/6, so the distortion of the output voltage of the magnetic sensor 4 due to the saturation of the MR elements can be canceled and output variation with the spacing is reducible.

Further, in the figure, 25 for blowing flow rate adjustor, 27 for standard differential pressure means and 33 for correcting value holding means are respectively shown.

Abstract: PURPOSE:To enable a device to operate more positively so as to augment the safety of crew by arranging a weaving retraction mechanism so as to permit an elongation due to a weaving to be automatically retracted when a retractor is locked accompanied with a rapid deceleration of a vehicle. CONSTITUTION:When a body is subjected to an excessive deceleration as in the case of a vehicle collision, an emergency lock type retractor R is allowed to be in a locked condition as usual permitting a pull-out by a weaving to be locked.

Title: Charge coupled device
Inventor: SASAKI EIKO
IPC: H01L29/76
Filed: 1986-01-10
Abstract: PURPOSE:To make it possible to set a potential an a voltage higher than a power source voltage and to obtain a wide output dynamic range without decreasing high transfer efficiency, by using a BCCD as a means for resetting the potential of the diffused layer in an output part. CONSTITUTION:After charge is as an output signal is taken out, a pulse PR1, which is applied to gates 17 and 18, becomes a high level. THe signal charge (e) is stored beneath the gate 18. An inner potentiaL phiFD in an electrical floating region 2 at this time agrees with an inner potential of neighboring gate 17 at a high level. The phiFD is reset at, e.g., 10V. Then the PR1 becomes a low level (gate voltage is 0V) and is returned to the original state. At a time t3, the inner potential at the gate 18, wherein the charge is stored, becomes 6V. In order to transfer the charge beneath the gate 18 excellently, a DC voltage is applied so that an inner potential at a gate 19 becomes 7V. By providing a CCD at the neighboring gate of the electrical floating region 2, the inner potential phiFD can be made larger than a power source voltage, without changing the power source voltage.

IPC: H01L21/027
Filed: 1992-01-09
Abstract: PURPOSE:To improve the resistivity property of resist etching by adding halogen atoms into the composition of carbon resist as a constituent element. CONSTITUTION:The hydrogen in the saturated carbon part of novolac resin is replaced with the halogen atoms such as chlorine and the like, and a halogen- containing photoresist is obtained. Also, in the case of polymer of saturated carbon chain, halogen atoms are introduced, and a halogen-containing photoresit is formed. At this time, the molar fraction of halogen atom content in the resist should be higher than the molar fraction of hydrogen atom content. The active particles such as halogen atoms and the like are projected on the surface of resist as the pretreatment of dry etching. As a result, the reaction activity of resist is lowered, and the etching resisting property against dry etching can be improved.

Title: Image forming device
Inventor: ONO MAKOTO
IPC: G03G15/16
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To enhance image forming accuracy by preventing a second toner image from being longer than a first toner image, at the time of forming the second toner image on the second surface of a transfer material, after the first toner image is formed on the first surface. SOLUTION: The first toner image T1 on a photoreceptor drum 1 is transferred to the first surface S1 of the transfer material S (a). After that, the transfer material S is turned inside out and the second toner image T2 on the drum 1 is transferred to the second surface S2 . At this time, power is supplied to a solenoid 6, to shorten a plunger 6a and an arm 7 is turned in the direction of an arrow, to raise a pressurizing spring receiver 3, so that the pressurizing spring 3 is shortened to make the pressing force of a transfer roller 2 against the drum 1 greater. Therefore, the diameter of the transfer roller 2 is made smaller.  Thus, a transfer material carrying speed v2 at the time of performing the transfer to the second surface, which tends to be faster by the toner image T1 which has already been transferred/fixed is made the same as a transfer material carrying speed v1 at the time of performing the transfer to the first surface, to prevent the second toner image T2 at the time of performing the transfer to the second surface from being elongated in the carrying direction of the transfer material.
