Title: Recording method and apparatus
Inventor: KOBAYASHI TOSHIMASA
IPC: B41J2/325
Filed: 1994-04-15
Abstract: PURPOSE:To always perform visually good recording not causing a white stripe or high density joint like stripe between lines even in the recording of an image having graduation properties by superposing first recording and second recording one upon another so that density is made lower than that of other region in the adjacent region of them. CONSTITUTION:In the overlap of recording dots, the terminal dot jm of an Ai line and the head dot j1 of an Ai+1 line are overlapped to set the recording density of both dots to 1/2 that of other dots. For example, in the case of shift, quantity S=0, the recording deNsity of the mutually overlapped dots jm, j1 is 1/2 the recording density of other dots not overlapped each other and, therefore, at the overlapped place, sum total recording density is same to other density and no recording density difference is generated. In the case of S=+1, dots jm-1, j1 are overlapped and the sum total recording density is only 1.5 times the recording density of other dots and, since an overlap position is expanded to a position of two dots, it is inconspicuous.

Filed: 1982-06-17
Abstract: PURPOSE:To obtain a sliding surface which has higher slidability and wear resistance than by the prior art, by smoothing the surface of the dispersion plating applied on the surface of a metallic object then subjecting the surface to liquid honing with the abrasive grain mixture mixed with two kinds of large and small abrasive grains thereby making said surface rugged and projecting the dispersant. CONSTITUTION:Powder (dispersant) of SiC is dispersed uniformly in an Ni plating soln. With an object to be plated as a cathode and an Ni bar facing said object as an anode, electric current is flowed between both electrodes to apply dispersion plating 2 on a substrate 1. After the surface of the plating 2 is smoothed with a known method, the smoothed surface is subjected to liquid honing with the abrasive grain mixture mixed with two kinds of large and small abrasive grains having different grain sizes. As a result, large ruggedness 4, 5 is formed on said smooth surface; at the same time, the SiC (dispersant) is projected from the plated surface with the small abrasive grains. Since the surface is free from contamination by chemicals that arises with electrochemical polishing and is finished to the good appearance, the surface has excellent merchandise value.

Title: Detection of fault point for cable
Inventor: YOSHIDA SHOTARO
IPC: G01R31/08
Filed: 1986-05-06
Abstract: PURPOSE:To locate a fault section accurately, by measuring a fault current flowing through a metal sheath at each insulated connection box to compare measured values between adjacent connection boxes. CONSTITUTION:At each insulated connection box 20, three cross-bonded wires 24 are grouped at one point to measure currents flowing through the wires 24 with current sensors 28. In other words, a ground-fault current flowing through a cross-bonded wire 24a at a position D on the side of a power source 16 at a fault point 30 is measured as large current value with the current sensor 28 provided at the position D. A fault current is divided equally in three through a ground wire 26 with an ordinary connection box 22 provided at the subsequent position E while flowing to the power source 16 side in the same phase and hence, a measured value with the wires 24 grouped will be almost the same as the current value at the position D. At positions F, G,... a large current is also measured with the sensors 28. On the other hand, current hardly flows through the wires 24 and only a small current is measured with the sensor 28 on the load 18 side. The same results are obtained at the positions J, K,.... The sizes of outputs of the sensors 28 between adjacent boxes 22 are compared thereby determining the location of the fault point 30 to be between the positions D and H with a simple construction.

Filed: 1995-04-27
Abstract: PURPOSE: To provide the structure of a packing case of which the cushioning/supporting effect is improved without increasing the using quantity of a cushioning material. CONSTITUTION: When an internal frame 3 is formed by folding a corrugated fiberboard sheet from respective folding lines, one edge 6 of the corrugated fiberboard sheet is formed on the inside of a cushioning member 4a at a specified location. When an article 5 to be packed is placed in the internal frame 3, a protruding part 5a of the article 5 to be packed comes into contact with the cushioning member 4 with the one edge 6 of the corrugated fiberboard in-between. An impact due to dropping, etc., can be received by the one edge 6 of the corrugated fiberboard and cushioning member 4.  By the cushioning property of the corrugated fiberboard itself, and because of the linkage between the one edge 6 of the corrugated fiberboard sheet and other sheet area, a reaction wherein the impact is received with a cushioning effect is presented, and the impact being applied to the cushioning member 4 is dispersed. Therefore, even when the cushioning member 4 and article 5 to be packed are confronted with a small area, the cushioning member 4 is prevented from being broken due to the impact, and the cushioning/supporting action by the cushioning member 4 is sufficiently displayed.

Filed: 1979-08-15
Abstract: PURPOSE: To enable the measurement of a part of a wave form in an enlarged scale, by coupling a diode in parallel with an oscilloscope to prevent the input of phenomena except for the measured part.  
     CONSTITUTION: Both the terminals of a noninductive resistor 2 for converting a current, which flows through a diode 1 to be measured, into a voltage are connected to a measuring instrument (oscilloscope) 4 through a limiting resistor 3. A diode 5, which serves to remove the positive part of a wave from to change it into another wave form shown in Fig. (a), is connected to the measuring instrument 4. The diode 5 is effective if its forward voltage drop is small. A resistor 3 is connected to reduce the forward current of the diode 5 to hold its forward voltage drop down. According to this constitution, the electric wave form is trimmed and the scale of its part to be measured is enlarged. Thus, the part of the wave form can be measured in the enlarged scale independently of the dynamic range of oscilloscope.

The quantity E of irradiated light in each unit area of the hologram base plate is Pl/V when the energy density of incident light speed is P, the width of the light flux is l and the moving speed is V. Thereby, the incident optical energy can be optionally controlled by changing P or V.
