IPC: H01L43/12
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To output an electric signal only by magnetic ink by forming a second protective thin film, formed with the same material of that of a first thin film, having no short-circuit film, on the first thin film, and forming input and output electrodes on both sides of the second thin film on a magnetic substrate. SOLUTION: In an electromagnetic conversion device 20, a first thin film 1, connected to a magnetic substrate 5, has a conductive film 2 discontinuously formed on its one surface, and has a protective film 6a on the other surface. Further, a second thin film 8 having no conductive film has a protective film 6b on its one surface. Further, an input electrode 7a is formed on both end surfaces of the substrate 5, and an output electrode 7b is formed on the first thin film 1. The first thin film 1 with the ordinary conductive film 2 has a resistance which varies in accordance with change of an external magnetic field and an applied voltage. The second thin film 8 has a resistance which varies in accordance with an applied voltage.  Thus, electric signals are independently amplified by amplifiers, and inputted into differential amplifiers so as to have opposite phases, and voltages by the applied voltage cancele each other, then electric signals only by magnetic ink are outputted from a magnetic sensor.

Title: X-ray image pickup device
Inventor: YONEYAMA AKIO
IPC: G01N23/04
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To shorten the measuring time by making an X-ray device conformable to a plurality of wavelengths, and performing a measurement by use of a wavelength in which the measuring time is minimized. SOLUTION: A wavelength λ in which the measuring time is minimized is calculated by a computer 13 from the thickness of a subject obtained from a subject holder 12 and the preliminarily inputted composition of the subject. On the basis of the calculation result, the reflecting mirror of a spectral part 2 is rotated by dθM to regulate the wavelength of incident X-ray to λ. On the basis of the calculation result, an X-ray interferometer stage 4 is also rotated within the horizontal plane by use of an X-ray interferometer stage rotating drive part 15 so that the incident angle of X-ray to an X-ray interferometer 5 is the Bragg angle. Since the slippage of optical axis accompanying the rotation of the spectral part 2 is 2dθM, the rotating quantity dθ of the X-ray interferometer stage 4 is dθ=sin<-1> (λ/2d)-2dθM from the positional relation between the spectral part 2 and the interferometer 5. In the expression, (d) is the lattice plane interval of crystal. Since the measurement of a phase contrast image can be performed in a wavelength where the measuring time is minimized according to the thickness of the subject, the measuring time can be shortened.

Title: Manufacture of electrophotographic sensitive body
Inventor: YASHIKI YUUICHI
IPC: G03G5/05
Filed: 1984-05-17
Abstract: PURPOSE:To prevent uneven film thickness in the layer structure of a photosensitive body and to maintain sensitivity constant even if an electrostatic charge transfer layer is uneven in film thickness by confirming the fact that the length expressed by formula I corresponds to the uneven film thickness part of the charge transfer layer in a step of forming a charge generating layer by dip coating. CONSTITUTION:The length of the charge transfer layer from the start line of coating till the coat film thickness becomes constant is obtained by integrating pulling velocity with respect to time, as shown in formula I in which the substrate-pulling velocity from t=0 to t=T1 is V1, and the velocity from t=T1 to t=T2 is V(t), and it is accelerated from V1 to V2 in the coating step of the charge generating layer. T1, V1, and V(t) are controlled so that formula I may be valid and T2 is claculated. Since the charge transfer layer becomes constant in film thickness beyond this length, the substrate is pulled up in the constant velocity of V2 from the time T2 till all of the substrate is pulled up. The charge transfer is formed on the charge generating layer by coating.

Title: Amorphous solar battery
Inventor: SASAKI HAJIME
IPC: H01L31/052
Filed: 1984-05-15
Abstract: PURPOSE:To improve efficiency, by providing an irregular structure on an Ti/ Ag/Ti layer, which is provided in the interface between an amorphous film and a stainless steel substrate, irregulary reflecting light, thereby lengthening the entire light path length to the length twice the thickness of the amorphous film. CONSTITUTION:On a stainless steel substrate 2, whose surface is finished in a mirror, Ti/Ag is evaporated by using an electron beam evaporation method at a room temperature. Thus the mirror surface substrate is obtained. The substrate is annealed at 300-800 deg.C, and Ti is evaporated. A Ti/Ag/Ti layer 3b having an irregular structure is prepared in this way. Light is scattered from the irregular structure of the amorphous solar battery, which has the Ti/Ag/Ti layer 3b having the irregular structure, which is obtained by annealing Ag. Therefore the length of the light path becomes long. Even if the thickness of an amorphous film is the same as that of the conventional device, the amount of light absorption is increased in comparison with the conventional device. Thus the conversion efficiency of the amorphous solar battery can be improved. The irregular structure of the Ti/Ag/Ti layer by the annealing can be readily realized by a relatively inexpensive, simple device.

Title: Hydraulic wrench used for mounting and demounting of bolt and nut
Inventor: SHIBATA TSUGIO
IPC: B25B21/00
Filed: 1992-04-17
Abstract: PURPOSE:To shorten a time required for transfer to a subsequent fastening work after completion of fastening of a bolt and a nut and to improve working efficiency by providing a switching valve unit by which an oil pressure circuit to a pilot valve is switched to the backward movement direction of a drive rod when a working oil pressure is reduced. CONSTITUTION:Operation of a hydraulic pump is stopped by means of the spool 6d of a pilot valve interlocked with the drive rod 5a of a hydraulic cylinder 5, and a switching valve unit 7. When a working oil pressure is reduced, working oil flowing from the switch valve unit 7 toward the pilot valve flows in a direction in which the drive rod 5a is moved backward. Thus, when a frame is brought into contact with a reaction force support after fastening of a bolt and nut or completion of fastening, operation by the hydraulic cylinder 5 does not work on the bolt and nut, whereby a constraining force between the reaction force support and the frame is rendered ineffective. As a result, working time can be shortened.
