Patent JP-H11283363-A (JP)
Title: Semiconductor memory
Inventor: FUJIMA SHIRO
IPC: G11C11/401
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent the operating margin of a sense amplifier from depending upon external supply voltages by swinging a dummy word line between the two fixed voltages generated in a semiconductor substrate to make the swing quantity of the dummy word line constant. SOLUTION: The dummy word line is swung between the two fixed voltages generated in the semiconductor substrate. Since levels of an internal step-up power source and an internal step-down power source to be used in this are both higher than threshold values of enhancement type MOS transistors for capacity coupling, the swing quantity of the dummy word line does not depend upon the threshold values. Since dummy word lines are swung by the fixed voltages generated in voltage generating circuits being in the semiconductor substrate, that is, by utilizing the level of the internal step-don power source to be used in a memory cell array part and a sense amplifier part and the level of the internal step-up power source to be used in a word line driver, it is unnecessary to provide voltage generating circuits newly in the semiconductor substrate.

Title: Formation of phosphated film on steel surface by chemical conversion treatment
Inventor: MATSUDA SHIGEKI
IPC: C23C22/13
Filed: 1982-05-18
Abstract: PURPOSE:To principally cause an electrochemical general corrosion reaction, to facilitate the control of a chemical conversion treatment bath, and to stably form a dense phosphated film, by regulating the temp., pH and oxidation-reduction potential of the bath to proper values. CONSTITUTION:In the formation of a phosphated film on the surface of a steel material by chemical conversion treatment, a treatment bath to be used is regulated to 0-40 deg.C, 0.5-5.0pH and 300-700mV oxidation-reduction potential (standard hydrogen electrode potential). The amount of metallic zinc ions in the bath is adjusted to about 60-100pts.wt. per 100pts.wt. phosphoric acid. By controlling the bath as mentioned above, an electrochemical general corrosion reaction is caused on the steel surface at ordinary temp. to form a dense phosphated film. Since the bath is used at ordinary temp., it is easily controlled, and the consumption of energy can be reduced.

Title: Form carrier device in printer
Inventor: IWASHITA YOSHITAKA
IPC: B41J13/10
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To effectively utilize opening dimension of the click of a clamper and to prevent looseness from being generated in a timing belt by providing a back-up roller, in which dimension of outside diameter is nearly same as the turning diameter of a timing belt in a second pulley, between the second pulleys so as to be rotated coaxially with the second pulley. SOLUTION: A back-up roller 28 is provided on the same axis as a second pulley 25 between the second pulleys 25. The dimension of outside diameter of the back-up roller 28 is nearly the same as the turning diameter of a timing belt 26 in the second pulley 25. The back-up roller 28 supports the pressing force of a clamp lever together with the second pulley 25 and is integrally rotated together with the second pulley 25. As a result, sinkage of a clamper 5 is prevented at time of pressing. Thereby, opening dimension of the click of the clamper 5 is effectively utilized and unnecessary extension is not given to the timing belt 26. Insertion and hold of photographic paper are performed more surely.

Title: External magnetic field correction device for cathode ray tube
Inventor: SATO MITSUO
IPC: H04N9/29
Filed: 1995-04-10
Abstract: PURPOSE: To easily correct the tilt of a screen, the color slippage, etc., that are caused by an external magnetic field which is made incident on the screen of a cathode ray tube. CONSTITUTION: The correction of a magnetic field is inputted through an operation of a button of an input part 1, and the data corresponding to the input correction are generated by an MPU 2. Then the data are converted into the analog voltage by a DAC 3 and applied to an operational amplifier 4 to undergo the non-inverted amplification. The converted data are outputted in a low impedance and then applied to the NO bases of both transistors TR Q1 and Q2. The amplifier 4 sets the resistors R1, R2 and R3, so that the output voltage is set at 0V when the voltage applied from the DAC 3 is kept at a reference level and also that a desired amplification degree is secured.  The emitter current of the TR Q1 flows when the base voltage is set at (reference voltage + VBE) or higher, and the emitter current of the TR Q2 flows when the base voltage is set at (reference voltage - VBE) or lower respectively. These emitter currents flow to a magnetic field correction coil L. The coil L is placed on the screen of a cathode ray tube or at the outer circumference of a deflecting yoke, and an external magnetic field is corrected by a generated magnetic field.

Filed: 1987-04-08
Abstract: PURPOSE:To easily grasp and correct error control information by vidualizing and outputting information relating to the contents of an error based on designating information when the error exists in control information. CONSTITUTION:A host computer 1 sends formed and edited document information to an input buffer memory 2. A data analysis function part 3 sends the input document information as it is in case of no designation from a control part 10, and at the time of receiving a designation, analyzes the input document information and, when an error exists, generates information relating to the contents of the error. A page buffer memory 4 stores the input document information, control information, the error control information, and error contents information. An output processing function part 5 converts the contents of the memory 4 into dot pattern information and develops the converted information in an image buffer memory 6 (the input document information itself is not developed). After ending the development, the contents of the memory 6 are transferred to a printer engine part 8 through a printer I/F part 7. Consequently, the error contents information of the error control information can be converted into a visual image and sent to the printer.

Title: Portable information processor
Inventor: HIROYA MASAAKI
IPC: G06F3/048
Filed: 1990-04-02
Abstract: PURPOSE:To display new information on a screen continuously without changing a part where an operator reads characters by displaying data on a display part from its head line and overwriting new data from the head line again when the data comes to the tail line. CONSTITUTION:When a data display instruction is inputted from an input part 3, a control part 5 reads data out of a storage medium read part 1 and stores the data in a storage part 4. Then the control part 5 transfers the data from the storage part 4 to the display part 2 at a display speed equal to the speed of storage in the storage part 4 and displays the data. The display part 2 on receiving the data begins to display the data from its head line, displays the data on a next line when the line becomes full, and overwrites and displays the data on last data from the heat line again when the tail line is reached. Consequently, the new information can be displayed on the screen continuously without changing the part where the operator reads characters.
