Title: Toner cartridge for picture forming device
Inventor: SHIINA YOSHIO
IPC: G03G15/08
Filed: 1989-02-28
Abstract: PURPOSE:To reduce the fluctuation of resisetance and force by toner to eliminate the occurrence of noise and fault and vibrations of a driving section by making a toner stirring and carrying member to a spiral form. CONSTITUTION:A toner stirring and carrying member 6 is constituted in such a way that the section of the member 6 which is slid on the inner wall of a toner cartridge 1 has a spiral form and part of the member 6 can be exposed always to the space formed of the toner 4 in the cartridge 1 and inner wall of the cartridge 1. Therefore, since the influence caused by the fluctuation of a rotating load to a driving section when the member 6 gets into the toner from the space can be eliminated, the rotating load to driving source can be reduced and the fluctuation of the load can be uniformized. As a result, the capacity of the cartridge 1 for toner can be increased and the cartridge exchanging frequency can be reduced.

Title: Insulated gate type field-effect transistor
Inventor: ISHIZAKA MASASHIGE
IPC: H01L29/78
Filed: 1990-02-27
Abstract: PURPOSE:To increase working speed by burying a magnetic substance layer into a section adjacent to a gate region except source-drain. CONSTITUTION:A magnetic substance layer 4 generating a magnetic field perpendicular to the direction of source-drain and parallel with the surface of a gate electrode 2 in a region including at least a channel is formed to a section adjacent to a gate region except the source-drain. Consequently, electrons to be moved in the direction of the drain while having charges (e) by an electric field between the source-drain region is subjected to Lorentz's force in the direction of CC' by a magnetic filed formed in the direction of A'A by two opposed magnetic substance layers, in a channel formed near the interface of Si-SiO2 upon application of a voltage between the gate electrode 2 and a P-type silicon substrate 1. Since electrons in the channel are separated from the interface of Si-SiO2 by the Lorentz's force, scattering on the interface of Si-SiO2 of electrons is reduced, thus maintaining electrons in high mobility. Accordingly, high speed can be attained.

Title: Pseudo fault generating system for information processing system
Inventor: NAKAMURA AKIHIKO
IPC: G06F11/22
Filed: 1989-02-28
Abstract: PURPOSE:To automatically produce a fixed pseudo fault as well as the intermittent pseudo faults by setting a pseudo fault code to a pseudo fault generating means of a processor via a pseudo fault setting means of a diagnosing device and producing a pseudo fault. CONSTITUTION:If a mode flag (A)40 of a diagnosing device 4 is set while a pseudo fault is being set together with a mode flag (B)41 set in a fixed pseudo fault mode, a pseudo fault setting means 45 sets again a pseudo fault code to a pseudo fault generating means 30 of a processor 3 during execution of a test program of the processor 3. Thus a fixed pseudo fault is apparently produced. If the flag (A)40 is set while a pseudo fault is being set together with the flag (B)41 set in an intermittent pseudo fault mode, the intermittent pseudo faults are produced since no pseudo fault is produced during execution of a test program of the processor 3. No pseudo fault is produced in a normal system operation state as long as the flag (A)40 is kept in a normal state.
