Title: Device for supplying ultra-high-purity gas
Inventor: OMI TADAHIRO
IPC: C23C14/24
Filed: 1986-07-05
Abstract: PURPOSE:To enable the supply of gas having ultra-high purity to a semiconductor producing apparatus with a device for supplying the gas to said apparatus by providing a ceramic filter to a piping for conducting the gas to the gas introducing port of the producing apparatus. CONSTITUTION:A valve 4 is first closed and valves 2, 3 are opened to release gaseous Ar through a check valve 5 into the atm. Electric current is caused to flow from a power source 6 to the pipings 3', 7 to electrically heat the pipings and the gas is passed through the ceramic filter 1 and is then released to the outside of the system, by which the gaseous impurity adsorbed to the filter 1 are effectively removed. The power source 6 is then turned off to return the gas and pipings to the ordinary temp. The valve 3 is thereafter closed and the valve 4 is opened to supply the gaseous Ar to the semiconductor producing apparatus.

Title: Structure of cell stack assembly for fuel cell
Inventor: HIROTA TOSHIO
IPC: H01M8/24
Filed: 1984-07-28
Abstract: PURPOSE:To achieve improved rigidity of a cell stack assembly which is formed by stacking a few cell units by using horizontal beams to connect studs which are used to clamp and fix the cell stack. CONSTITUTION:While a clamping pressure is applied to a unit cell stack and terminal plates superimposed on the upper and the lower surfaces of the unit cell stack, reaction gas supply and evacuation manifolds 23-26 are attached to the four side surfaces of the stacked body to form a cell unit 2. Next, a few cell units 20 are stacked and then the stacked cell units 20 are fixed between end plates 3 and 5 through studs 6 by clamping. After that, T-shaped horizontal beams 9 made of a rigid steel are fixed to the studs 6 by means of bolts 11, thereby making a cell stack 1. Accordingly, it is possible to make the entire cell stack highly rigid, thereby improving the shock resistance of the cell stack.

Abstract: PURPOSE:To improve pressure resistance, to reduce the degrees of swelling and contraction and also to swell nonspecific adsorption of protein by forming a hydrophilic polymer layer of a thickness in a prescribed range on the surface part of a hydrophobic crosslinked polymer particle. CONSTITUTION:A hydrophobic monomer constituted of an aromatic compound having two or more vinyl groups and a polymerization initiator such as a benzoyl peroxide are diluted or dissolved by toluene, for instance, and added to a dissolution water phase of a suspension stabilizer.

Abstract: PURPOSE:To sufficiently enhance the error correction capability to each string even when an error rate differs from a modulation signal string by using a modulation signal replacement section and a restoration demodulation signal string replacement section to replace a signal string between an error correction coding function and a digital multi-value modulation state. CONSTITUTION:In the case of 16aAM multi-value modulation for a signal whose symbol is arranged at a sender side, four transmission input signals D11-D14 are used, a code error correction coding section 1 inserts different signals ID1-ID4 to each signal string as additional bits, error correction is coded independently to each string and the result is outputted as signals D21-D24. A modulation signal string replacement section 2 replaces matrix in the unit of 4 strings and spread to modulation signals D31-D34, and a 16aAM modulation section 3 is used to provide the signals D31-D34 as a signal D40. A receiver side demodulates the signal D40 by using a 16aAM demodulation section 4 to provide outputs of signals D51-D54, and a demodulation signal string replacement section 5 establishes decoding synchronization for error correction to restore the signals into the original signal string.

Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To allow a mobile robot to go forward by escaping an area incapable of traveling in the case of a mobile robot having a finite radius which travels by acknowledging a position error. SOLUTION: When an area N incapable of traveling is present on a path A leading to a prescribed target T in geographical data D obtained by sensing, an escapable traveling path A3 at a constant steering angle for escaping the area N incapable of traveling is set in a range capable of traveling of a mobile robot R itself in the geographical data D, and a traveling driving mechanism is controlled based on the escapable traveling path A3 until the geographical data D are obtained by the next sensing. Afterwards, in this method for controlling the traveling of the mobile robot, the setting of the escapable traveling path and the control of the traveling driving mechanism is operated for each updated geographical data D. Thus, the area N incapable of traveling can be surely escaped, and a calculation load can be saved by unnecessitating the overlapping of the geographical data D.

Title: Analog type electronic watch
Inventor: NAKAMURA JIYUNPEI
IPC: G04G5/02
Filed: 1977-12-26
Abstract: PURPOSE:To let the second hand position and second counter coincide by so arranging the watch that at least the second counter starts counting from 0 at the time of pushing the winding crown in the case of providing the second counter and starting hand operation after manual time setting. CONSTITUTION:A protrusion 9 is provided to a winding crown 8. When the hand operation is stopped by pulling the winding crown 8, a switch 5 is closed, hence the frequency dividing part 2 and second counter part 3 are put in a reset state and no second pulses are sent to the motor part 4 and therefore the hand operation stops. Hence, in the case of performing the hand setting of the watch, the hand operation is stopped by pulling the winding crown 8 when the second hand comes to the just hour position, at which time the hour and minute hands are set, thence the winding crown 8 is pushed in. This causes the switch 5 to open and the frequency dividing part 2 to be released of reset and start frequency division again. Since the second counter part 3 starts from 0, the second indicated by the second hand and the second indicated by the second counter part 3 coincide exactly.

Title: Impact dot printer

IPC: B41J29/08
Filed: 1992-06-18
Abstract: PURPOSE:To reduce the noise of an impact dot printer and increase the attenuation of a sound wave of 1kHz or more by partially changing the cross-sectional area of the printing paper discharge route between a paper guide member and a cover. CONSTITUTION:Sound suppressing members 1a are provided over two or more stages in close vicinity to the upper surface 17c of the paper discharge plate 17 positioned above a print head 8 and a platen 6 and the sound wave advancing along the upper surface 17c of the paper discharge plate 17 can be effectively suppressed. That is, when there is a part changed in cross-sectional area in the a sound wave transmission route, the particle speed of a medium becomes discontinuous across the part and the reflection of a sound wave is generated. Since the reflection of a sound wave becomes large as cross-sectional area change quantity becomes larger and the protruding quantity of the sound suppressing member 1a to the printing paper discharge route is larger than that of a sound suppressing member 2a and the cross-sectional change quantity of the member 1a is larger than that of the member 2a, large sound suppressing effect is obtained. Since the reflection of a sound wave is repeated by a plurality of the sound suppressing members 1a, 2a, the energy of a sound wave is attenuated.

Abstract: PURPOSE: To extract a character area out of various input images without performing any complicated processing and to exactly divide the area correspond ing to the attribute of an image by dividing the image area while defining proximate pixels, for which density level difference is less than a threshold value, as the same area. CONSTITUTION: As the image information of the image read by a scanner 1, a position coordinate and a density level for each picture-element (pixel) are stored in an image buffer 2, for example. A relation discriminating part 3 performs labelling processing for applying a common label to two pixels, for which the position coordinates are mutually proximate and the difference of density levels is smaller than the threshold from the image information stored in the image buffer 2. A divided result output part 5 divides the pixels in the image, for which the value of an element in a correspondent label buffer 4 is common, into the area composed of pixels having the same label. An area attribute discriminating part 7 discriminates the attributes of respective divided areas based on the geometrical features of respective areas, density distribution and mutual inclusive relationship.
