Abstract: PURPOSE:To simplify the constitution of a developing device and to reduce the cost by providing a doctor which controls the bristling of a developer between developing rollers in an upper and a lower adjacent developing tank, placing their two projection parts closely to the upper and lower developing rollers, and using the doctor in common. CONSTITUTION:The developing tanks 21 and 14 which have the developing rollers 22 and 25 and agitator rollers 23 and 26 are united vertically and adjacently and the doctor 27 which has the projection parts 27a and 27b is supported rotatably on a partition late 40a. When the doctor 27 swings clockwise about a point P, the projection 27a comes close to a sleeve 22a while an extremely small gap g1 is left to supply no developer to the surface of a photosensitive body, and the projection 27b comes close to a sleeve 25a while a gap g2 is left to supply a bristled developer to the photosensitive body. When the doctor 27 rotates counterclockwise, the opposite state is set. Thus, only one doctor swing to control the developer, so the number of component is decreased to simplify the constitution and reduce the cost.

Abstract: PURPOSE: To make it possible to select an outline on the definite basis of criteria by deciding a distribution of values of the time integration which maximizes the contents of information regarding an image for expressing a spin resonance distribution, and deciding in advance the number of impressions of a pulse and gradient array. CONSTITUTION: The apparatus, in which an object 5 having an atomic spin in a magnetic coil 2 is arranged, has a means 6 to impress the pulse and gradient array. In the case that the object 5 includes protons and the spin resonance distribution is measured as a proton density of the object 5, a generator 19 synchronizes with the Larmor frequency ω0 of protons, and, in the coordinate system that rotates with the frequency ω0 , a magnetized M is rotated by an angle which is decided by an rf pulse. Further, the first gradient Gy has a variable time integration against the different pulse and gradient array to obtain the resonance signal.  When the second gradient Gx is impressed in the period from t2 to t4 and the two-dimensional Fourier transform is carried out to the sample value 22, the spin resonance distribution is formed and the outline distribution PD is realized to obtain the maximum contents of information regarding the image during measuring spin resonance signals.

Title: Testing device for semiconductor parts
Inventor: HANDA HIROMITSU
IPC: G01R31/26
Filed: 1985-07-19
Abstract: PURPOSE:To test the electric characteristics of parts fitted to a printed circuit board highly accurately by forming a pad for directly extracting important signal and voltage supply on semiconductor parts without passing the signal and voltage supply through the printed circuit board. CONSTITUTION:When a signal having a large transient current or a power supply is connected to lead terminals 4, surface side wiring pads 5 of printed circuit boards 10, through holes 6, and spring pins 11 through back side wiring pads 5, a noise may be generated due to the resistance of the path and the influence of inductance. Thereby, a highly accurate test for the electric characteristics of the parts is impossible. Consequently, a large transient signal or current is connected to the pin 11 through the pad 7 directly fitted to the semiconductor parts without passing the signal or current through the terminal 4. In addition, the signal or current is connected to a signal power supply wiring 9 on the printed board 8 of the testing device to supply signal and voltage to the testing device. Consequently, a malfunction due to noise generation caused by the influence of resistance and inductance and the reduction of accuracy due to the deterioration of electric characteristics can be suppressed.

Title: Cache control
Inventor: SUZUKI MASAHIRO
IPC: G06F12/16
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To guarantee the rightness of data in a cache memory and to improve reliability by controlling a memory so as to store a data block in the cache memory only when a comparison result by means of a comparator is right. SOLUTION: The inspection part of a duplexed data block group is transferred from an external device 04 to a controller 03 with connection 12. The controller 03 executes control so as to transfer it to the comparator 05 with connection 10 and, at the same time, to output the data block stored in the memory 02 to the comparator 05 with connection 15. The comparator 05 compares data from connection 15 with that from connection 10 for the portion of data block length and outputs a right value or a false value to the controller 03 with connection 11. Only when an input value from connection 11 is right, the memory 02 is controlled so as to output the data block stored in the memory 02 to the cache memory 01 with connection 14.
