Title: Measurement method of particle diameter and average particle diameter of ultrafine particle
Inventor: MITOME MASANORI
IPC: G01N15/02
Filed: 1992-02-20
Abstract: PURPOSE:To measure a particle diameter and an average particle diameter of an ultrafine particle by obtaining a plasmon energy from an electronic energy loss spectrum which is measured by an electron ray source and an electronic energy analysis device. CONSTITUTION:Plasmon energy which is generated within an ultrafine particle is affected by quantum size effect when the particle diameter is reduced and becomes larger than that of a large crystal. Since a relationship which is expressed by a specific expression exists between plasmon energy and a particle diameter d of the ultrafine particle, a single particle diameter of the ultrafine particle which exists in a minute area which is equal to or less than 10mum is calculated by measuring plasmon energy within the ultrafine particle. Furthermore, an average particle diameter of a plurality of ultrafine particles can be obtained by measuring plasmon energy of a plurality of ultrafine particles with a particle diameter distribution. Plasmon energy can be obtained by measuring an electronic energy loss spectrum. Namely, the electronic energy loss spectrum is measured by an electronic energy analysis device while being exposed to electron beam from electron ray source.

Abstract: PURPOSE: To provide an inertial navigation apparatus by which the function of every accelerometer can be inspected in a state that the body of an airplane has been aligned and placed horizontally. CONSTITUTION: Accelerometers 2a to 2c are attached in directions of coordinate axes (x, y, z) which have turned, by a prescribed angle, three airframe axes (X, Y, Z) of a flying body 1. The coordinate axes (x, y, z) of the accelerometers 2a to 2c are set in such a way that, after the coordinate axes (X, Y, Z) have been turned (pitched) by -45 deg. around, e.g. the Y-axis, they are turned (rolled) by +45 deg. around the X-axis. Then, accelerations which have been detected by the accelerometers 2a to 2c are input to an acceleration conversion and arithmetic part, and components which correspond to the x-axis, the y-axis and the z-axis are converted into components which correspond to the x-axis, the y-axis and the z-axis so as to be output to a computer part.  When the accelerometers are attached to the directions of the axes in which the reference axis of the body of an airplane has been turned to a pitching direction and a rolling direction, the respective accelerometers detect respective accelerations of gravity so as to be output even in a state that the body of the airplane has been aligned and placed in the horizontal state. As a result, the function of all the accelerometers can be inspected.

Title: Stabilized electrophotographic method
Inventor: MIYAGAWA NOBUHIRO
IPC: G03G15/043
Filed: 1983-04-22
Abstract: PURPOSE:To control the surface charge potential of an amorphous silicon type photoconductive layer practically at the same level in the 1st process and the 2nd process or after by exposing a photosensitive body precedently by the light having light intensity practically the same as that of picture exposure prior to the 1st process. CONSTITUTION:A stabilizing lamp 15 is arranged on the upper side of a corona charger 3 for main electrostatic charge. The stabilizing lamp 15 lights up at the 1st electrophotographic process and a photosensitive layer 2 is precedently exposed by the stabilizing lamp 15 at first before the start of copying and then copying processes are executed in the order of main electrostatic charge by the charger 3 and picture exposure. Although the stabilizing lamp 15 is turned on only in the 1st process at the time of continuous copying, a light fatigue effect is provided by picture exposure and exposure by a destatisizing lamp in the 2nd copying process or after, so that it is unnecessary to turn on the stabilizing lamp 15. The stabilizing light source 15 is defined so that the light intensity on the photosensitive layer 2 practically coincides with that of the photosensitive layer 2 at the time of picture exposure.

Title: Switch mechanism for copying machine
Inventor: SUZUKI SEIICHI
IPC: H01H21/28
Filed: 1985-04-04
Abstract: PURPOSE:To decrease the number of switches for securing operation and safety by turning off a main switch through an actuator when a front door is open and turning on the main switch when the front door is closed. CONSTITUTION:When a knob 3b is pressed while a copying machine is not used, the lower end 10b of an actuator 10 presses down the operating element 5a of the main switch 5, which is then turned on. When the front door 6 is opened, an actuator 11 moves to right associatively, so the actuator 10 is pressed up by the inflection part of the actuator 11 against the spring force of a leaf spring 8. Consequently, the operating element 5a moves up and the switch 5 is turned off. Then when the front door 6 is closed, the actuator 11 moves to left, so the inflection part of the actuator 11 disengages from the actuator 10, which moves down by the spring force of the spring 8. Consequently, the lower end 10b of the actuator 10 presses down the operating element 5a again to turn off the switch 5. Consequently, the function and safety are secured by only one main switch.

IPC: G01N1/10
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To enable accurate comparative assessment in a hydrogen determination assay by a decompression and solidification test by maintain the temperature of a molten metal constant at the time of starting decompression. SOLUTION: A K thermocouple 3 which is vertically moved by an electromagnet 2 is immersed in sampled molten aluminum in a crucible 4 by approximately 5mm in a vacuum container with a capacity of approximately 1000cc. A vacuum pump 6 which produces a vacuum through a suction valve 5 can be turned on/off via a power relay contact 7, and the output to the relay can be desirably set by measured values of a temperature measuring device 8. Differences occur owing to temperatures at the time of starting decompression even with the same molten metal in a conventional device, but differences hardly occur owing to the activation of sampling when the temperature at the time of starting decompression is maintained at e.g. 700 deg.C in the device of this invention.  Therefore, this invention enables accurate comparative assessment in a hydrogen determination assay by a decompression and solidification test and eliminates dispersion caused by operators.

Abstract: PURPOSE:To obtain an IC, the degree of integration thereof is high and which functions at high speed, by forming an electrode wiring layer in the multilayer constitution of poly Si and Al and doping the impurity of the same conduction type as the diffusion layer of a substrate to the connecting section of the diffusion layer of a substrate  to the connecting section of the diffusion layer and poly Si. CONSTITUTION:An opening is forned to a SiO2 film 12 on an N type Si substrate 11  and a P layer 13 is shaped, and the wiring layers of poly Si 14 and Al 15 are formed.  The P type impurity is diffused from the whole surface of diffused to poly Si from the  P layer 13 in the opening section in the poly Si 14, and both the poly Si 14 and the P  layer 13 are kept in the same conduction type. According to this constitution, even  when the opening of the film 12 protrudes from the layer 13, the layer 13 can small be  shaped because the direct alloying and short circuit of the upper Al wiring 15 with the Si substrate 11 can be avoided by the presence of the P type poly Si layer. Contact resistance does not increase in the contact of wiring and the layer 13 because both the  wiring and the layer 13 are made of Si, both may be connected in minute size, and the  IC, the degree of integration thereof is high and which functions at high speed, is obtained.
