IPC: H04L1/00
Filed: 1992-05-25
Abstract: PURPOSE:To accurately decide the violation of declaration of cells by comparing the space between a cell to be decided and its precedent cell with the threshold space. CONSTITUTION:A supplied cell (a) is temporarily stored in a buffer 11 with a cell synchronizing pulse (b) received from a cell synchronizing circuit 12. A signal (d) which detected the cell detecting information (c) through a cell detecting circuit 14 is supplied to a cell inflow monitoring circuit 13A. Then a cell space detecting means consisting of a counter 21, a memory 22 and an adder 23 detects the space between a cell and another cell preceding by (n) cells and supplies the cell space to a comparator 24. Meanwhile a minimum call space computing circuit 27 calculates a prescribed minimum cell shape, and this space is supplied to the comparator 24 of each corresponding stage and compared with each corresponding cell space obtained by the cell space detecting means. When the cell space is smaller than the minimum cell space, it is decided that the cell to be decided runs counter to the declaring conditions. Thus the violation of declaration can be accurately decided for cells.

Filed: 1982-07-30
Abstract: PURPOSE:To make a device small-sized and reduce its production cost by moving back and forth a valve plate made in one body with a planet bearing to a valve seat section to open or close the fluid passage by means of the revolution movement of the planet bearing of a valve device. CONSTITUTION:When a drive gear 22 is driven by a motor 5, an engaged planet gear 21 starts its rotation and is revolved along an inner gear 20.

Title: Picture display device
Inventor: HIRONAKA NORIHIKO
IPC: H04N5/68
Filed: 1990-05-23
Abstract: PURPOSE:To prevent the luminance change and the color deviation by converting deflection data in a deflection memory to an analog current by a D/A converter and converting it to an analog voltage by an operational amplifier and inputting it to a differential amplifier to amplify the voltage and giving a deflecting signal to a horizontal deflecting electrode. CONSTITUTION:Deflection data sent from the deflection memory is converted to an analog current by a D/A converter 50 and is converted to an analog voltage by an operational amplifier 52 and its feedback resistor 52. The analog voltage is inputted to a transistor TR 54 and is shifted by a cascade TR 56 and a resistor 58. Thereafter, the current is amplified by a TR 64 to give horizontal deflecting signals h and h' to horizontal deflecting electrodes 18 and 18' by output buffer TRs 69 and 70. Thus, the variance in center voltage and amplitude voltage of the horizontal deflecting signal due to the voltage variance of horizontal deflecting high power and horizontal deflecting power or the temperature change is difficult, and a picture display device free from luminance change and color deviation is realized.

IPC: B01D63/02
Filed: 1985-06-19
Abstract: PURPOSE:To facilitate the mutual connection of modules and to reduce pressure loss, by receiving a hollow yarn bundle in a housing comprising a straight pipe having a side pipe and fixing the opening parts of hollow yarns to the end part of the side pipe and allowing the hollow yarn bundle to be partially present in the side pipe part and the straight pipe part. CONSTITUTION:A hollow yarn bundle bundled in a U-shape or a hollow yarn bundle 3 opened at one end thereof and sealed at the other end thereof is inserted in a straight pipe 1 having a side pipe 2 from the side pipe part thereof. A fluid to be treated is introduced into the straight pipe 1 from the end (a) thereof to be filtered by the hollow yarn membrane while the filtered fluid is passed through the hollow yarns to be taken out from the side pipe end (c). The fluid not filtered is taken out from the other end (b) of the straight pipe. Because the fluid to be filtered straightly flows through the straight pipe, pressure loss is reduced. When this module is connected in series, the necessary number of stages are connected by a connection straight pipe member 5.

IPC: H01L21/761
Filed: 1985-06-19
Abstract: PURPOSE:To increase the separation withstanding-voltage, by forming a second buried layer having a lower impurity concentration than that of a first buried layer, on the lowest withstanding-voltage section of junctions determining the separation withstanding-voltage. CONSTITUTION:An integrated circuit device comprises a one-conductive type semiconductor substrate 1, an epitaxial layer 2 of the opposite conductive type lying thereon, and a first high concentration buried layer 13 of the opposite conductive type being buried between the substrate 1 and the epitaxial layer 2. In this case, a second buried layer 14 with a lower impurity concentration than that of the buried layer 13 is formed so as to cover the side faces of the buried layer 13. At this time, the separation withstanding-voltage is not determined by the side faces of the buried layer 13, but is determined by the junction between the substrate 1 and the bottom of the buried layer 13 with a lower impurity concentration positioned below the dotted line as shown in the figure. In this way, a high separation withstanding voltage can be attained.

Title: Surface potentiometer
Inventor: SUZUKI KOUJI
IPC: G01R29/12
Filed: 1977-11-09
Abstract: PURPOSE: To measure the positive and negative surface potentials of a surface to be measured by generating the signals, which are synchronized with such a chopper as is rotating at a constant speed between the surface and a measuring electrode, so that the AC signals induced by the measuring electrode may e clamped by the signals.  
     CONSTITUTION: A chopper 2 is driven by a motor 6, and the surface potential (a) of a surface 1 to be measured acts upon a measuring electrode 7 to induce an AC voltage so that it is converted into signals (b) by a surface potential measuring circuit 9. On the other hand, by the actions of a Hall element 4 and a synchronous signal generating circuit 5, there are generated signals (c) which are synchronized with the rotations of the chopper 2. Since the synchronous signals (c) are generated when the chopper shields the electrode 7 with the maximum area, they are  synchronized with the minimum point of the output (b), when the surface potential is positive, and with the maximum point when the potential is negative. The signals (b) and (c) are fed to a synchronous circuit 10, and the DC reproducing output (d) is extracted so that the surface potential of the surface to be measured can be measured in accorance with the polarity of the signals (d).

Filed: 1992-05-27
Abstract: PURPOSE:To prevent the drift of the integration value and the overflow of a counter which are easily produced when the minute bias is superposed on an integrated input signal in regard of a digital integration circuit using an up-down counter. CONSTITUTION:A comparator 1 samples the polarity of an analog integrated signal SA and converts this signal into a 1-bit digital up-down signal UD. Then an up-down signal control circuit 6 is provided between the comparator 1 and a counter 2 which counts up or down the signals UD. Then the circuit 6 produces an UP or DOWN signal of the polarity opposite to the integration value SO for each input of an impulsive control signal SC and prevents the scattering of the value SO when the integration lasts for a long time by setting the value SO back to 0 by a single count amount.
