Abstract: PURPOSE:To improve the braking efficiency by making a judgment on locking based on select-low effected between right and left rear wheels which are conditioned to select-low and each of right and left front wheels when a driving system is conditioned to a direct four wheel drive. CONSTITUTION:Right and left rear wheel sensors 3RR and 3RL are connected with a low select circuit 8a, the output side of which is connected with one of the input terminals of other low select circuits 8b and 8c. And the other input terminal of these low select circuits 8b and 8c is connected with right and left front wheel sensors 3FR and 3FL. Owing to this constitution, the right and left rear wheels RR and RL are conditioned to select-low by the low select circuit 8a wherein select-low is effected by the low select circuits 8b and 8c between said wheels conditioned to select-low and the right and left front wheels FR and FL thereby permitting a logic circuit 9a or 9b to make a judgment on locking based on the aforementioned situation. As a result, the braking efficiency can be improved even in two systems.

IPC: G03G21/00
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent execution of copy operation for reproducing a prohibited color input image faithfully without imposing uncomfortableness to a client. SOLUTION: A coin processing machine connected through a communication line 301 with the communication control section 199 of a copy machine 1 is provided with a switch 306 being operated at the time of setting an operation mode of the copy machine 1.

Filed: 1990-04-09
Abstract: PURPOSE:To easily convert an existing computer to enable high speed operation without changing any program by changing a CPU or the other circuit to a high-speed circuit in the conventional computer and further adding an address decision circuit and clock switching circuit. CONSTITUTION:When an address signal to be applied from a CPU 2 to a ROM 1 is a program part to be executed by a high-speed clock without changing the program part currently under execution, a switching signal to be outputted for an address decision circuit 5, which receives this address signal, is turned to 'H' corresponding to the high-speed clock and the CPU 2 is operated at high speed. Reversely, in the case of a program part not to be executed by the high-speed clock without changing the program part currently under execution, the switching signal to be outputted from the circuit 5 is turned to 'L' corresponding to a low-speed clock and the clock to be applied from a low/high- speed generator 4 to the CPU 2 is changed from high-speed to low-speed. Then, the CPU is operated at low speed.

Title: Magnetic polishing material and manufacture thereof
Inventor: TADENUMA KATSUYOSHI
IPC: B24D3/00
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide magnetic polishing material solving problems of strength, polishing force and chemical corrosion resistance in a conventional magnetic polishing method by improving the corrosion resistance of the magnetic polishing material, including grinding material, and forming the magnetic polishing material in porous structure. SOLUTION: This magnetic polishing material containing hard grinding material is low in the wear of polishing material and high in polishing force. Furthermore, corrosion resistant material is used as a magnetic component to permit the use of high concentration acid, and retainability of an etching solution is improved by forming porous structure. In the case of polishing particularly the side face or upper face of the inner surface of large diameter piping or a large-sized tank, the etching solution is not separated from the magnetic polishing material so as to dispense with the trouble of specially spraying the etching solution.  If the etching solution is formed in a micro granular state, for instance, magnetic adhesive strength to an external magnetic pole is increased to prevent a fall caused by the mutual collision of magnetic polishing material grain when the magnetic polishing material swings as the external magnetic pole flucuates, and this permits effective polishing and decontamination of radioactive contaminant.

Title: Manufacture of semiconductor device
Inventor: TANIDA TOSHIHIRO
IPC: H01L21/3205
Filed: 1979-07-25
Abstract: PURPOSE:To prevent disconnection of a metallic electrode in the semiconductor device by superimposing an oxide film containing a PSG layer by a low temperature vapor phase growth on a thermally oxide film and forming an opening thereat and forming an oblique surface on the inner wall. CONSTITUTION:The opening is perforated at the thermally oxide film 2 on an N type Si substrate to form a P<+> type source 3 and a drain 4. Then, an SiO2 layer 12 containing a PSG layer is formed by low temperature vapor phase growth, and is selectively perforated with openings. In this case the SiO2 film 12 is wrong with adhesivity with a resist to cause the etching speed of the PSG layer to become fast, and the film 2 is accordingly sidewisely etched to form oblique surfaces on the inner walls of openings 8c-8d. SiO2 film 12 is removed, and new thin SiO2 films 2a-2c are formed thereon, and electrodes 5-7 are attached as the conventional process. Since this configuration can form oblique surface on the wall of the opening for the electrodes, no disconnection occurs at the metallic electrode so as to obtain a highly reliable device.

Title: Copy density control method
Inventor: SEZOKO SHINICHI
IPC: G03G15/08
Filed: 1984-05-15
Abstract: PURPOSE:To raise quickly the copy density without time delay if an operator wants to raise it quickly and to supply a toner to a developing machine in accordance with this rise of the copy density, by operating a toner dispenser for toner supply for a certain period in accordance with the operation of a copy density selecting part when this selecting part is operated in the copy density raising direction. CONSTITUTION:When a ''thick'' button 10 is depressed, a developing roll voltage control pat 11 changes the voltage of a developing roll of a developing machine so that the copy density is raised. If the copy density is raised temporarily, the exposure may be changed by an exposure control part 12 otherwise. When the ''thick'' button 10 is depressed, the voltage of the developing roll is changed in this manner, and simultaneously, a dispense motor is operated for a certain period by a dispense motor control part 14 in parallel with the control of the developing roll voltage control part 11. That is, if the operator depresses the ''thick'' button 10, the copy density is raised without time delay, and the toner is supplied to the developing machine in parallel with this rise of the copy density.

Title: Image reading device
Inventor: ADACHI NOBUKAZU
IPC: H04N1/00
Filed: 1985-05-07
Abstract: PURPOSE:To provide possibility of smooth reverse feeding of an original text sheet without risk of jamming even after the sheet is exhausted from the separator part by rotating either of a transport member and a separating member in the direction of feeding the sheet reversely when the sheet is to be fed reversely, and by equipping the other member with a means not to transmit the torque. CONSTITUTION:A motor 13 is operated in the regular direction to send original text sheets to a separator part A. At this time, a one-way clutch 15 is put in locked condition to rotate both a transport belt 4d and a separator belt 5d clockwise, and the original text sheets 2 are transported upon being separated one from another while situated between the two belts 4d, 5d. When an original text sheet 2 which has passed the separator part A is to be fed reversely, the same motor 13 is operated in the reverse direction to put the one-way clutch 15 in free condition, so that no drive force is transmitted to the separating shaft 5a. Therefore, the separator belt 5d stops when the sheet 2 is fed reversely with running of the transport belt 4d, wherein the reverse feeding action will not encounter any obstacle. Accordingly there is no risk of jamming to ensure smooth reverse feeding.
