Title: Fet solution component sensor
Inventor: UNO SHIGEKI
IPC: H01L29/78
Filed: 1988-03-22
Abstract: PURPOSE:To prevent the infiltration of water and moisture into electrode parts and to improve reliability by forming the sensitive gates, electrode pads and leads of FET elements to an opposite surface and molding the pads and leads by using a frame and resins. CONSTITUTION:Islands 2 of silicon are formed by etching the upper silicon layer of a silicon wafer. The electrode pads 3, 3' of the drains and sources of the FET elements are provided on the islands 2 and further, the sensitive gates are provided to the base of the islands 2 to form chips. Chip holding holes 13 and leads 12 are previously provided on the substrate 11 and the chips are installed in the holes 13 to electrically connect the pads 3, 3' and the leads 12. The frame 14 larger than the holes 13 are thereafter placed on the chips and the silicone resin and epoxy resin are packed into the frame. Since the pads and leads are provided on the surface opposite to the sensitive gates, the immersion of the pads and leads in a soln. is obviated and the infiltration of the water and moisture is prevented by the frame and the packed resins. The reliability is thus improved.

IPC: G21K7/00
Filed: 1988-03-22
Abstract: PURPOSE:To enhance resolution and magnification by detecting X-ray images while finely adjusting a two-dimensional X-ray detector in perpendicular biaxial directions with respect to the optical axis and processing many sheets of the resulted X-ray images. CONSTITUTION:This X-ray microscope has the two-dimensional X-ray image detector 201 and a piezo element 203 which finely adjusts the detector in a direction X. The detector and the element are moved respectively in the directions X, Y by the voltage values from a driving section 204. A sample 105 is excited to emit fluorescent X-rays by the excitation X-ray emitted from an X-ray source 101. The magnified fluorescent X-ray image of the sample is formed on an X-ray detector 107 by an X-ray objective optical element 103. This X-ray image is converted by an image pickup section 108 to an electric signal which is sent as a digital image to a memory and data processing section 109. The detector holder is thereafter finely adjusted by 0.5mum in the X-axis direction by a driving section 111 and the image is taken into an image memory. The same effect as the effect of using the X-ray detector having the substantially high resolution is thereby obtd.

IPC: B65H75/02
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To facilitate printing on a bobbin and facilitate the maintenance of a printing mechanism by printing on the bobbin for winding up a transcribing sheet or an image receiving sheet by a laser. SOLUTION: For example, a bar code 2 is printed on a curved face part on the surface of a bobbin 1 by a laser, a lot number is printed on the curved face part on the surface of the bobbin 1, or a lot number is printed in a hollow part inner face of the bobbin 1. A timing in printing on the bobbin by the laser is preferable to be at the same time of winding up a transcribing sheet or an image receiving sheet and it is preferable to print on the cassette case in a type using a cassette case for storing the bobbin. This constitution can facilitate printing on the bobbin having no flat part and also facilitate the maintenance of the printing mechanism. This can also facilitate the printing on parts, which are hard to be printed by an ink jet, such as a curved part and a bobbin inside.

Title: Fm demodulator
Inventor: AOKI MASAYUKI
IPC: H03D3/00
Filed: 1987-03-20
Abstract: PURPOSE:To obtain a stable output without an influence due to the dispersion of element by digital-converting an FM modulated wave by using two conversion clocks with different delay times, and further, multiplying the difference of the outputs, inverse-sideconverted, by a constant. CONSTITUTION:A signal, inputted from an FM modulated wave input terminal 1, is digital-converted by A/D converters 4, 5. The conversion clock of the converter 5 lags behind the conversion clock of the converter 4 by a very short time  t, because it is inputted through a delay line 3. The outputs of the converters 4, 5 are inverse-sine-converted respectively by ROM tables 6, 7, and the phase part of the FM modulated wave is taken out and inputted to a subtracter 8. The subtracter 8 subtracts the output of the table 7 from the output of the table 6, and the derivative of the phase is obtained by multiplying the result of said subtraction by 1/ t by a multiplier 9, and the FM demodulated wave is outputted from a terminal 10.

Abstract: PURPOSE: To prevent the occurrence of imperfect separation phenomena and obviate the production of defects in the patterns printed on the substrates to be processed such as semiconductors by letting an organic compound be adsorbed on the surface of a photo mask in its vapor.  
     CONSTITUTION: An inert gas is introduced from a lead-in pipe 6 inot an outside box 1 and the gas in the box 1 is exhausted to the outside through an exhaust pipe 7. Next, an organic compound 4 such as sulfonic acid derivative is evaporated by the heating heater 2 connected to a power source transformer 3 and is adsorbed in island or laminar form on the surface of a photo mask 5 having been drawn with desired patterns. Next, this mask 5 and the substrates to be processed having been coated with photosensitive material are contacted, whereby the patterns of the mask 5 are contact-printed to the substrates to be processed and are then exposed. This obviates the production of the defects owing to the entry of opaque foreign material in the patterns having been printed on the substrates to be processed.

Title: In-busy channel switching method for mobile communication system
Inventor: KANAI TOSHIHITO
IPC: H04B7/26
Filed: 1988-03-18
Abstract: PURPOSE:To eliminate hitting time attended with a busy channel switching by applying time division multiplex to plural speech channels so as to synchronize with each other in each carrier frequency and assigning the channel such that the timewise consecutive speech channel group is not used in adjacent radio zones. CONSTITUTION:In order to synchronize carrier frequencies f1, f2...fn respectively, 12 speech channels are subject to time division multiplex to constitute speech channel groups T1-T12 a by the speech channels in the same timing. The speech channel groups T1-T12 are assigned to each radio base station so that the timewise consecutive speech channel group is not adjacent radio base stations. If the mobile terminal equipment in a BS-A using the speech channel of the speech channel group T1 is moved to the radio zone of the adjacent radio base station, the speech channel group assigned newly has a time difference of one time slot or over, the speech test is conducted by selecting the speech channel group assigned newly while the communication is being made by the speech channel T1.

Title: Take-up roller
Inventor: KITAMURA KICHIJI
IPC: B65H75/38
Filed: 1986-03-25
Abstract: PURPOSE:To dispense with the lashing and releasing of an operated member as well as to aim at improvement in controllability over rope winding operation, by making the lock and rotation of a winding drum so as to be automatically performed by diametral expansion and contraction of a coiled spring in a fixed tube. CONSTITUTION:When an input shaft 4 is rotated clockwise, a working piece 4a comes into contact with one side hook part 8b of a coiled spring, pressing it. And, a coil diameter of the coiled spring 8 is contracted whereby a pressure state to a fixed tube 6 is released, while the hook part 8b comes into contact with a taction part 5 of a winding drum 5, pressing it. With this pressure, the winding drum 5 is rotated together with the coiled spring 8 in the same direction, thus drawing or winding of an operated member is carried out. Next, when operation is stopped, working force is loaded on the drum 5 from the side of the operated member, and the drum 5 is loaded so as to be rotated clockwise or counterclockwise, but the taction part 5b presses one side of these hook parts 8a and 8b of the coiled spring 8, expanding the coil diameter of the coiled spring 8 and forcibly pressing it to the fixed tube 6, thus rotation is locked by frictional force so that no lashing is required.
