Patent JP-H01310704-A (JP)
Title: Fluid purifier
Inventor: HATTORI SHUJI
IPC: B01D53/38
Filed: 1988-06-07
Abstract: PURPOSE:To make pressure drop small and also to improve purification capacity by arranging a plurality of pieces of activated carbon which has many holes perforated to the passage direction of fluid and is molded in series while keeping a specified interval. CONSTITUTION:Activated carbon 1a-1c wherein many holes 2 perforated respectively to the passage direction of fluid are provided and it is molded are arranged to the inside of a pipe 4 while keeping the intervals 3 to the flow direction of fluid. Fluid incorporating the components to be removed is allowed to flow to the direction shown in an arrow and the components are removed by adsorption of activated carbon 1a-1c and catalytic action thereof. In this case, pressure drop can be small inhibited by many through-holes 2 provided to activated carbon 1a-1c. Further, when activated carbon is divided into about three pieces and arranged in series in comparison with such a method that the molded form is used as it is long, the surfaces of the cutting planes can be effectively utilized and purification capacity is improved by causing turbulent flow in the space of the intervals 3.

Title: Wire cut electric discharge machine
Inventor: INOUE KIYOSHI
IPC: B23H7/02
Filed: 1987-06-05
Abstract: PURPOSE:To improve machining precision, by a method wherein a machining voltage or a machining current during control of an increase in tension is detected, and when it is similar to that during linear machining feed, control of an increase in tension is stopped, and control of the stop of machining feed is released to perform variation of the direction of the machining feed. CONSTITUTION:Though no influence is exercised on machining precision even when bending occurs to a wire electrode 2 during machining of a linear part, when a guide 5 is moved to a point A, a direction variation signal is outputted from an NC control device 12. However, since, in this case, the antinode part of bending of the wire electrode 2 is present at a point B, a control circuit 14 controls an increase of tension through braking of a brake 7 by means of a direction variation signal, and an NC device 12 stops a machining feed effected with the aid of motors 10 and 11. When a machining current detected by a detecting circuit 16 is similar to a machining current during linear machining feed, a control device 15 releases control of an increase in tension by means of a control device 14, releases control of the stop of a machining feed, effected by means of the NC device 12, and varies a machining feed direction. This constitution performs normally reliable correction of bending and enables improvement of machining precision.

Title: Manufacture of compound semiconductor device
Inventor: WATANABE KOJI
IPC: H01L21/338
Filed: 1990-05-29
Abstract: PURPOSE:To make an element, a constituent of a gas, mixed in the vicinity of the surface of a semiconductor substrate being shallower than the degree Rp of a range of ion implantation and thereby to facilitate the increase of carriers in the surface by forming a conductive layer in the surface by exposing it to a plasma discharge using a gas or by depositing a high-melting metal on it after it is exposed to this plasma discharge. CONSTITUTION:Si ions 100 are implanted selectively into a substrate so as to form thereon an active layer 2 to be an n-type conductive layer. Next, a plasma processing is applied to the surface of the substrate 1 by a reactive ion etching method wherein a mixed gas 200 of SF6 and CF4 is used, for instance. Then, WSi being a high-melting metal, for instance, is deposited on the substrate and a WSi gate 3 is formed by dry etching. Thereafter the plasma processing is executed again by using a mixed gas 300 of SF6 and CF4, and then an (n) conductive layer 4 to be a source, a drain and a resistor is formed by implanting Si ions 400. Afterward, an n<+> conductive layer 5 to be electrodes of low-resistance source and drain resistors is formed selectively by implanting Si ions 500. Thereafter an NSG film 6 is deposited and heat treatment is executed in an atmosphere of hydrogen. Lastly, an ohmic electrode 7 is formed by removing the NSG 6, and a transistor Tr and a resistor R are formed.

Title: Demodulation circuit for msk modulated wave
Inventor: KURIMURA SHIZUO
IPC: H04L27/14
Filed: 1993-05-21
Abstract: PURPOSE:To perform an easy and stable demodulation operation by sampling a standard wave by the trigger pulses of the same period as the baud rate of modulated data from MSK signals. CONSTITUTION:The output gate signals H of a gate signal preparation circuit 8 are sampled by a trigger signal B in a sampling circuit 9 and a signal for discharge is outputted when one part of the signals H is sampled. Thus, the MSK signals are accurately frequency-devided and outputted until the baud rate of the modulated data by a first frequency divider. The trigger pulses whose pulse width is narrow are prepared by a generator 3 for the respective cycles of the frequency division. A second frequency divider 5 frequency-divides highly accurate high frequency signals added to an input terminal 4 and prepares the standard wave equivalent to the non-modulation time of the MSK signals. Thus, the variation of phases at every cycle due to noise included in the MSK signals is cancelled in the process of the frequency division and thus, since sampling and demodulation are performed with the trigger pulses of the same period as the baud rate with strong S/N, the crack of the signals and mixed pulses are not present at all in demodulation data and the stable demodulation of MSK modulated waves becomes possible.

Title: Image forming device
Inventor: TOKIEDA KENICHI
IPC: G03G15/16
Filed: 1990-05-31
Abstract: PURPOSE:To excellently perform a transfer even if a sheet having a high moisture content is used by controlling a voltage applied on a transfer means corresponding to conducting between a pair of guiding members coming in contact with a recording medium. CONSTITUTION:A sheet P is carried from a right side to a left side between a photosensitive drum 201 and a transfer unit 301, and the guiding member 503 is formed with a conductive material such as stainless, and constituted of a upper guiding plate 503a and a lower guiding plate 503b. When a prescribed voltage is applied on a corona wire 301a, and the moisture content of the sheet is made high, a charge flows into the upper guiding plate 503a from the lower guiding plate 503b via the sheet P, and the self bias voltage of a control shield 301c is increased together with the increasing of the moisture content of the sheet. When the voltage applied on the transfer means is controlled corresponding to the increase of the flowing of the charge, the transfer corresponding to the electrical properties of the recording medium can be executed. Thus, even if the sheet having the high moisture content is used, the reduction in the density of an image and the disturbance of the image can be prevented.
