Title: Web tension control unit of rotary press
Inventor: IJICHI YUUJI
IPC: B65H23/16
Filed: 1984-02-17
Abstract: PURPOSE:To keep web tension constant and to maintain an estimate for a multicolor printing by displacing a floating roll disposed between an in-feed roll and a printing drum corresponding to fluctuations in web tension. CONSTITUTION:When tension of a web 11 increases, the web 11 is elongated to decrease the length of the web passing through an in-feed roll 5 and the length of the web 11' between the in-feed roll 5 and the printing drum 4 is integrally decreased, so that the tension of the web 11' is increased. A floating roll 12 which is unbalanced with tension of a spring 16 by an increase in tension of the web 11' is oscillated against the tension of the spring 16 to a position for balancing with tension increased for a change in length of the web 11' corresponding to an elongation percantage of paper, so that the length of the web 11' is controlled. Thus, the tension of the web 11' between the in-feed roll 5 and the printing drum 4 is kept constant to avoid a change in an estimate for multicolor printing.

Filed: 1987-02-12
Abstract: PURPOSE:To improve the withstand voltage characteristic under the normal operating condition by providing a projection on an outside grid electrode at the position facing one end of an inside grid electrode. CONSTITUTION:A cathode electrode K and the first-sixth electrodes 1-6 are provided almost coaxially, and the first-fifth electrodes are held by an insulating support bar 7 and insulated from each other. A circular body 16 is arranged and fixed inside the electrode 6 to face the end section 5a of the electrode 5 and constitutes a projection facing the end section 5a. The portion of the circular body 16 facing the end section 5a has a diameter nearly equal to that of the end section 5a, and the distance D1 is set to the distance D2 between the electrode 6 and the cylinder section of the electrode 5 or less. The projection is provided over the whole periphery of the end section 5a, thereby no distortion is generated on the electrostatic lens formed between the electrode 5 and the electrode 6, and it has an effect to concentrate the electric field at the time of knocking over the whole periphery of the end section 5a. Accordingly, a spark can be prevented from occurring during the normal operation, and the good withstand voltage characteristic can be obtained with the large-diameter lens maintained.

Abstract: PURPOSE:To prevent the reduction of store data, and the device from being complicated by switching an address of a display use storage means by a connection, so that whether it is placed in the same address as a random access memory or placed in a different address can be selected. CONSTITUTION:An allocated address of a storage means 105 is determined by an address selecting means 107, and since a connection of an address signal line 108 is switched by a selection switch 109, whether an allocation of an address of the storage means 105 is placed in an address overlapped with a random access memory 102 or placed in a different address can be selected. Accordingly, in the case of overlapping read-out of display data, the storage means 105 is placed in the address overlapped with the random access memory 102, and on the contrary, in the case of attaching importance to the data quantity to be stored, the storage means 105 can be placed in the address being different from the random access memory 102. In such a way, the reduction of store data and the complication of the device can be avoided.

Title: Commercial nonbreak changeover circuit for uninterruptible power source equipment
Inventor: OKAMURA KOICHI
IPC: H02J9/06
Filed: 1988-02-09
Abstract: PURPOSE:To prevent fluctuation of voltage upon switching a power source, by providing a means for detecting the voltage level of a commercial power source and inputting a detected commercial voltage level to the voltage regulating means for an uninterruptible power source equipment if a power source switching means is at the side of commercial power source. CONSTITUTION:When a load 8 varies and causes over current in an uninterruptible power source equipment 3, the power source for the load 8 is switched to a commercial power source 2. At the same time, one analog contact 23B of an analog switch 23 is opened while the other analog contact 23A is closed. Consequently, commercial source voltage detected through a metering transformer 21 and smoothing circuit 22 connected with the commercial power source 2 is inputted, in place of a set voltage set in a voltage setter 13, to a voltage regulating circuit 14. Consequently, output voltage from an uninterruptible power source equipment 3 is maintained continuously at a level matching with the commercial source voltage. As a result, the voltage does not drop excessively when switching to the uninterruptible power source equipment 3 is made, and surge current is suppressed.

Abstract: PURPOSE:To enable the black ground of a wide area and the black ground of a narrow area to be both developed with good reproducibility by providing the carrier of which the resistivity when a 10V/cm DC electric field is applied to 5-15 timee the resistivity when a 100V/cm DC electric field is applied. CONSTITUTION:The carrier of which the resistivity value when a 10V/cm DC electric field is applied is 10<8>-10<11>OMEGA.cm, the resistivity value when a 100V/cm DC electric field is applied is 10<7>-10<10>OMEGA.cm and the former is 5-15 times the latter is used. Such carrier is obtained by adding reduced iron powder into the water added with, for example, a silane coupling agent and controlled to 4.0pH with an acetic acid, and sticking a cationic conductivity imparting material to the heat- treated iron powder. By the use of the carrier, the formation of blank-out etc. on  the black ground of a wide area is eliminated, and the narrow balck ground of characters, line images, etc. is reproduced faithfully to the oringial. In addition, the  occurrence of the deterioration of the carrier after copying of multiple sheets is  made difficult.

Abstract: PURPOSE:To form regions having different life times simultaneously by providing two oxide films of different thicknesses. CONSTITUTION:When a substrate 11 has been prepared, a thick thermal oxide film is formed on the main surface of the substrate 11, the thermal oxide film located on an island region 17 is removed by performing an etching leaving the thermal oxide film on island regions 16 and 18. Then, the above is heat-treated in the dry O2 atmosphere containing HCl, and a thermal oxide film is formed. A Cl ion dose not reach the interfaces of films 19a and 19c at the part where thick thermal oxide films 19a and 19c exist, and even when HCl is mixed in, almost no change in life time is observed. On the other hand, the effect of HCl mixture is appearing at the part where the thin thermal oxide film 19b exists, thereby enabling to increase the life time. After the thermal oxide film 19 has been formed as above, p and n layers are formed by selectively diffusing impurities. Ohmic contacts 20-27 are then formed and an IC is completed by connecting these contacts.

Title: Spring material for dot printer
Inventor: SETO HIROYUKI
IPC: B41J2/28
Filed: 1986-02-14
Abstract: PURPOSE:To obtain a highly durable and reliable dot printer with minimum risk of breakage by using a molybdenum material molded of more than 99.0% purity molybdenum and capable of four 90-degree bendings. CONSTITUTION:A spring material 5 which regulates the operation of a printing wire 1 and dampens an impact inflicted on the printing wire 1 is formed in more than 99.0% purity molybdenum. The molybdenum material to be used should stand a 90-degree bending more than four times. Compared to the conventional dope tungsten material, the molybdenum material improves bending frequency until it is broken, and will not be broken even after printing of 100 million dots. Further if the purity of molybdenum is not more than 99.0%, the spring material can easily be broken during dot hammering and line drawing and its fabrication yield is very low. Thus the spring material 5 is exceedingly durable and is almost free from a breaking risk, contributing to the provision of a highly reliable not printer.
