Title: Electrostatic latent image developing carrier, its production, developer and image forming method
Inventor: TAKAHASHI SAKON
IPC: G03G9/113
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To obtain a carrier which has excellent ability to give proper and stable electrification property to a toner and can maintain its ability for a long time by dispersing resin fine particles containing a conductive powder in a coating resin to produce the carrier. SOLUTION: Resin fine particles 13 containing a conductive powder 12 are dispersed in a coating resin 11, which is applied on the carrier core material 10 to form a coating layer 20. The conductive powder 12 may be dispersed by mixing during polymn., by dispersing in an emulsion, or by dispersing during suspending to disperse in the resin fine particles 13. The average particle size of the resin fine particles 13 is preferably 0.05 to 3 μm. If the size is smaller than 0.05 μm, resistance is hardly controlled. If the size is larger than 3 μm, the particles easily drop from the coating layer 20 and can not maintain its function. Therefore, the obtd. carrier has excellent ability to give proper and stable electrification property to a toner and can maintain this ability for a long time.

Title: Gas sensor
Inventor: HACHIMAN SATOSHI
IPC: G01N27/16
Filed: 1981-07-30
Abstract: PURPOSE:To obtain a low cost sensor which permits the use of dry cells as an electric power source and can detect the density of gas with slight electric power and good accuracy by vapor-depositing a Pt electrode havng prescribed resistance values on an SiO2 substrate and forming a sputtering layer of PdO on the electrode surface. CONSTITUTION:A Pt electrode 2 is vapor-deposited on an SiO2 substrate 1 (size L1=2mm., L2=1mm., L3=0.05mm. approximately) and a PdO sputtering layer 3 is formed on the surface of the electrode 2. For example, 1.5V is applied between the terminals 4 and 4' of the electrode 2 of such sensor from a dry cell. When the resistance of the electrode 2 is 100OMEGA, the electrode attains 260-400 deg.C which is the catalytic activating temp. of PdO with 15mA current. When the sensor is brought into contact with combustible gases such as municipal gas, gaseous propane, or the like, the resistance value of the electrode increases linearly with a change by 1,000-5,000ppm gaseous density. Thus the sensor of the simple construction usable for sufficiently a long time with the dry cell is obtained without the use of commercial AC 100V power sources.

Title: Buffer memory fault processing system
Inventor: FUKUCHI KOICHI
IPC: G06F12/08
Filed: 1988-05-16
Abstract: PURPOSE:To evade a fixed fault generated in a buffer memory by dividing the memory area of the buffer memory into plural pieces, simultaneously reading them, and processing them according to the number of times of detection. CONSTITUTION:The memory area of a buffer memory 10 is divided into four 1-4. Data are simultaneously read from the respective areas through a prohibiting gate 11, and the fault is detected by an error checking circuit 14. At such a time, when the faults in the prescribed number are detected, the memory area is made into an unused condition, and the processing is executed. Next, when the data of the buffer memory 10 are read and the fault in the prescribed number are detected again, the divisions of the memory area to be made into the unused condition are switched division by division by a selector 16 until the fault is not detected. Thus, the effect of the fault can be evaded in the most effective form in which only one divided memory area having the fault is made into the unused condition.

Filed: 1979-09-20
Abstract: PURPOSE: To enable early decision on the identity of A-type hepatitis within a time range of four weeks by calculating the ratio of HA antibody value of serum and antibody value of serum having one gram of M antibody destroyed by 2-mercaptoethanol treatment.  
     CONSTITUTION: The HA antibody of test serum in the early stage of hepatitis is measured by RIA method. In the meantime, 2-mercaptoethanol is added to the test serum and inclubated. Then the HA antibody of serum having one gram of M antibody destroyed is measured by RIA method. The ratio of these measured values is calculated as M index. In case this M index value is equivalent to almost more than 1.5, the case is diagnosed as A-type acute hepatitis. While if the said value is equivalent to less than 1.5, the case is diagnosed as hepatitis other than the A-type. M-index is obtained as 1g M treated serum cpm/untreated serum cpm (cpm indicates the radioactivity in free second antibody by the competitive immunity radiactivity counting method).

Abstract: PURPOSE:To prevent any effect from being given to the transmission of an auxiliary signal such as a DSC signal by sending a signal having a constant logical value at the sending side with synchronous multiplex conversion with respect to the sending of a the fault signal of an appliance. CONSTITUTION:When a fault is detected by a fault detection circuit 102, a fault detection signal 4 fixed to a logical value 1 and an output signal 5 are led to an OR circuit 111.
