Title: Failure detector for semiconductor bridge main circuit
Inventor: SUZUKI TETSUJI
IPC: B62D6/00
Filed: 1994-09-09
Abstract: PURPOSE: To detect conduction failure of a semiconductor bridge main circuit element under shutdown state by providing a small circuit additionally. CONSTITUTION: Under a state where the upper arms U, V of a semiconductor bridge main circuit 1 are turned ON by a control circuit 7, voltage between the input terminals is detected by means of a voltage detection circuit 11. When the detected voltage is lower than a set voltage, the control circuit 7 makes a decision that a conduction failure is present in lower arm X, Y. On the contrary, a decision is made that a conduction failure is present in the upper arm based on a voltage detected when the lower arm is turned ON. The decisions are made under shutdown state of a unit comprising the semiconductor bridge main circuit.

Title: Automatic file restoring system
Inventor: YAMASHITA MASAO
IPC: G06F12/00
Filed: 1990-08-17
Abstract: PURPOSE:To relieve a secondary storage medium by saving an unupdated file information control table into the secondary storage medium. CONSTITUTION:A computer system is interrupted in an updating state by a factor like a software fault, a hardware fault, etc., which a file information control table 3 is updated in a memory and then started again at production of a new file 10. Under such conditions, the information storing records 5, 6 and 8 of the table 3 are copied to a file information control table 2 from a save area 4 where the unupdated table 3 is saved. Thus a state where no fault occurred yet is automatically restored. As a result, the table 2 stored in a secondary storage medium 1 is turned into its unupdated state and therefore contributes to the relief of the medium 1.

Filed: 1988-09-01
Abstract: PURPOSE:To shorten a time required for correction by providing a mode to perform X<1-gamma> (X: arbitrary Galois field data) in the mode of Galois field operation. CONSTITUTION:A circuit which calculates X<(1-gamma)> is provided in a Galois arithmetic circuit when G(X) in the generating function of reed-solomon is expressed in equation I. For example, a ROM 13 which outputs X<1-gamma> setting an address as a register X1, and a selector 14 which selects and outputs the output of an X<1-gamma> arithmetic circuit and that of a multiplier circuit 8 are provided. In other words, the Galois field arithmetic circuit inputs the data alpha<->pHi of a Galois field to a register in the Galois arithmetic circuit, and outputs alpha<->i<(1-gamma)> via the X<1-gamma> arithmetic circuit by the designation of an arithmetic mode. In such a way, operation alpha<->i<(1-gamma)> (i: arbitrary integer) on the Galois field required for the calculation of an error numeric value can be obtained without performing the operation repeatedly.

Title: Developing device which prevents image stain owing to defective ear cutting
Inventor: SUZUKI HIROHARU
IPC: G03G15/01
Filed: 1984-10-17
Abstract: PURPOSE:To convey effectively and uniformly a developer and to prevent the defective ear cutting on a developing sleeve by making the width of the lower magnets among the magnets provided in several stages toward an image carrying body shorter than the width of the upper magnets. CONSTITUTION:Both ends in the transverse direction of the magnets have a larger magnetic field inclination and the developer sticks more thereto than to the other parts. A large amt. of the developer accumulates gradually on the rollers in the positions corresponding to both ends of the respective magnets and the sure ear cutting is not executed from a lower scooping roller 27 toward a developing sleeve 24 if all the magnets 35, 34, 28, 29, 31, 32 are made to the same width. The length in the transverse direction of the magnets is thereupon made shorter with the magnets existing in the position further from a photosensitive body 1 with respect to the magnets 35, 34 in the sleeve 24 and the magnets 28, 29 in an upper scooping roller 27. Then the developer is effectively and uniformly conveyed and the defective ear cutting on the developing sleeve is prevented.

IPC: G06F9/52
Filed: 1986-09-12
Abstract: PURPOSE:To prevent abnormal decision of a terminal equipment by providing a control means which interrupts the command of data transmission and reception request of the terminal equipment during a processing time when this processing time required for completion of processing is inputted from the terminal equipment. CONSTITUTION:If a terminal equipment J cannot respond to the command sent from a master equipment M because the time for the processing is too long, the signal which interrupts the command request from the master equipment M and data of the command interruption time are outputted together with an acknowledge (ACK) signal from the terminal equipment J. The time sufficient for completion of the processing in the terminal equipment J is set as this command interruption time. That is, when the command interrupting request is issued, a command interrupting timer is started in the master equipment M to count, for example, one second. No commands are outputted to a terminal equipment J3 during this time. A prescribed processing is performed in the terminal equipment J3 during this time, and thereafter, the command signal is sent to the terminal equipment J3 because it can communicate with the master equipment M.

Title: Touch keyboard device
Inventor: NISHIHARA KAZUHIKO
IPC: G06F3/0487
Filed: 1990-08-17
Abstract: PURPOSE:To improve the operability and the workability of a touch keyboard at occurrence of an error by switching automatically the screen to a new screen where the image of a clear key is shown when an error state is set due to the misinput of a key. CONSTITUTION:If the misinput of a key occurs on a liquid crystal touch key board 21, the display screen of a liquid crystal display device 21b is switched to a screen showing the image of a clear key only. Thus the error is canceled with the input of the clear key. Thus it is possible to omit the conventional complicated operations where the display screen is shifted before and after one by one screen and the screen showing the image of the clear key is selected. In addition, an operator is urged to push the clear key since this key has a size larger than other keys. Consequently, the error caused by the misinput of a key can be simply canceled and the operating efficiency is improved.
