Title: Steel segment piece with joint box opened to its outer surface and method for constructing sunk body using the same
Inventor: SATO KAZUYOSHI
IPC: E02D23/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To improve a construction method whereby a cylindrical sunk body formed by connecting steel segment pieces is constructed as it is pressed, from a ring-shaped cutting edge installed along its lower edge, into the ground by the excavation of the ground inside it and the application of pressure from above, because the method requires scaffolding provided for connecting work inside the steel segment pieces to be installed and removed each time a process is repeated, so that the scaffolding does not get in the way of an excavator such as a hammer grab bucket when time excavator enters and exits. SOLUTION: A steel segment piece 21 has an approximately square skin plate 31, main girders 32 welded to the upper and lower ends of the square on the inner surface of the skin plate 31, a joint plate 25 welded to the right and left ends of the square, and a joint box 40 which opens to the edge of the skin plate 31. Operators insert hands into the joint box 40 from outside a sunk body to connect the adjacent steel segment pieces 21 together via the main girders 23 or joints. The need for inside scaffolding is eliminated.

Title: Electronic computer
Inventor: HAYAKAWA KAZUO
IPC: G06F13/28
Filed: 1991-07-01
Abstract: PURPOSE:To attain the transfer of data at a high speed by using properly a DMA system and an I/O system in response to the length of the data to be transferred between the processors. CONSTITUTION:In the processors 2-1 and 2-2, the DMA control parts 2-3 and 2-5 transfer the data in a DMA system and the CU control parts 2-4 and 2-6 transfer the data in an I/O system for each byte, word and double word. Then the data are transferred through the parts 2-4 and 2-6 in the case of the small length of data and through the parts 2-3 and 2-5 in the care of the large length of data respectively. That is, the time when a parameter is set for operation of the DMA system is compared with the time when the data are transferred in an I/O system when the data are transferred. If it is decided that the data transfer time of the I/O system is smaller than that of the DMA system, the data are transferred in the I/O system. If the time of the DMA system is smaller, then the DMA system is applied through the software having such a deciding logic.

Title: Detector for toner concentration
Inventor: AOKI MINORU
IPC: G03G15/08
Filed: 1983-08-31
Abstract: PURPOSE:To simplify the constitution of a toner concn. detector and detect toner concn. digitally and accurately by counting the oscillation frequency of a toner concn. detecting means on the basis of the zero-crossing point of a commercial electric power source. CONSTITUTION:When some of a developer falls in a sensor 1, a Colpitts oscillator 2 oscillates at the frequency corresponding to the toner concn. and sends its output signal to the counter terminal CT of CPU3. A detection timing signal generating circuit 4, on the other hand, outputs a pulse signal to the interruption terminal INT of CPU3 at every zero-crossing point of a commercial voltage. Consequently, the counting of the input signal from the oscillator 2 is started with the 1st pulse signal and stopped with the 2nd pulse. When the counted value is lower than a reference toner concn. set value, a toner supplement command is outputted from a terminal P to drive a motor 6 for a toner supplement member and when the counted value becomes coincident, a toner supplement stop command is outputted to hold the toner concn. inveriably at the set value.

Abstract: PURPOSE:To reduce the generation of unnecessary elements for moire generating factors caused by mixing the lower side wave component of the third higher harmonic wave of a frequency modulating signal into a used band by angle- modulating a special carrier with an input signal, and recording it on a magnetic recording medium. CONSTITUTION:When one cycle is set at T, a signal, whose level in zero to T/6 period is at zero, whose level in T/6 to T/2 period is at A, whose level in T/2 to (2/3)T period is at zero, and whose level in (2/3)T to T period is at -A, is made into the carrier, the carrier is angle-modulated by the input signal, and recorded on the recording medium. That is, at the time of recording, a video signal inputted from a terminal 1 is supplied to a frequency modulator 2, its frequencies are modulated, and its output signal is supplied to a 1/6 dividing circuit 3. The 1/6 dividing circuit divides the frequency modulating signal to the 1/6 frequencies, and two square signals whose phase are mutually different at 60 deg. are outputted. These two output signals are supplied to an adder 4, and added at the amplitude ratio of 1:1. Thus, the moire components can be reduced.

Abstract: PURPOSE: To install an acceptor impurity layer on the insulating film which covers the main surface of the semiconductor substrate and to diffuse the impurity through the window of the impurity layer into the substrate, thereby improving high voltage resistance of the planar-type thyristor, etc.  
     CONSTITUTION: An acceptor impurity layer, that is, borosilicate-glass layer 7, including window Wa formed on insulating film 5 which covers the main surface of a single-conductive-type semiconductor substrate (N-type silicon substrate) 1, is formed on the film 5, and another window Wb which is narrower than window Wa is formed. Through this window Wb, boron is thermally diffused into substrate 1 to from gate diffused region 3. At the same time impurity 9 (boron) in layer 7 is diffused into substrate 1 to lower the impurity concentration on the interface of film 5 in order to widen the width of the depletion layer on the main surface side of substrate 1, thereby making wider the radius of curvature of gate region 3. The device, which has been completed with the said arrangement and later steps, suppresses localized concentration of the electric field, thereby achieving improvement on dielectric strength.
