Abstract: PURPOSE:To print continuously by combining a one-side printing with a perfect printing, by a method wherein, a first font representing a normal character pattern and a second font representing a crosswise reverse character pattern are provided, and a video signal according to the setting direction of a recording paper is generated. CONSTITUTION:A page memory 43 stores per page unit an information 42 required for a printing on a recording paper. A character pattern generator 41 is provided with a first font representing a normal character pattern and a second font representing a crosswise reverse character pattern. According to the printing mode, i.e. a perfect printing or a one-side printing, a video signal generation controlling means 44 changes the order of reading the information stored in the page memory 43, and the read order per line in the font corresponding to the read character code, and sends it as a video signal. In the one-side printing, the information is read successively by every line from the first line in the page memory 43 ; in the perfect printing, it is read in the reverse order successively by every line from the last line in the page memory 43. In this manner, a continuous printing can be carried out without changing the paper setting direction even if a one-side printing is combined with a perfect printing.

IPC: H04B17/00
Filed: 1983-03-25
Abstract: PURPOSE:To discriminate a fault position speedily and securely in case of the occurrence of a fault by deciding on fault contents from the correlation between physical monitor information and logical monitor information. CONSTITUTION:If physical alarms 1', 3', 5', 6', and 7' and logical alarms 5'', 6'', and 7'' are generated within a specific time, the alarm generation is stored in a current-state storage area 23 and compared with the contents of a last-state storage area 24 to rearrange them in the increasing order of influence, e.g. 1', 3', 5', 6', 7', 5'', 6'', and 7''.

Title: Front and rear wheels steering apparatus for car
Inventor: SANO SHIYOUICHI
IPC: B62D6/02
Filed: 1984-03-15
Abstract: PURPOSE:To improve the turning performance by obtaining the smooth movement mode on turning traveling by controlling the steering for rear wheels according to the yaw angle acceleration. CONSTITUTION:The front-wheel steering-angle data obtained by a front-wheel steering-angle sensor 14 and the car-speed data obtained by a car-speed sensor 15 are input into a computer 12 and calculation-processed, and the rear-wheel steering control information is obtained. The final steering information increases as the yaw angle acceleration data increases. Therefore, if the yaw angle acceleration increases in the latter half of turning, rear wheels are steered largely in the direction having the equal phase for the front wheels. Even if the rear- wheel steering is controlled so that the turning movement of a car increases in the initial stage of turning, the turning movement is damped corresponding to the yaw angle acceleration in the latter half of turning.

IPC: B23K9/013
Filed: 1982-03-30
Abstract: PURPOSE:To perform stable gouging irrespectively of depth, by inserting a narrow groove gouging torch in the deepest part, and blowing off the metal melted by the arc heat by an inert gas in the atmosphere of the inert gas. CONSTITUTION:If the arc started part in the deepest part of a base material 11 during narrow groove welding exhibits a defective part 12 like a projection and obstructs the welding of the next layer, an arc is generated between a tungsten electrode 7 and the proejction 12 while an inert gas is flowed out under low pressure from a shielding gas pipe 3. The projection 12 is melted by the arc heat to molten state, whereafter an inert gas of a high flown rate is blow from a supply pipe 2 for gouging gas to blow off the molten metal in said part, whereby said part is removed. The projection 12 which is a welding defect is thus removed easily under the stable welding conditions.

Abstract: PURPOSE:To prevent adhesion of ink to a gap between a wire and a wire guide and to enable to perform a clear and steady printing, being excellent in quality, for a long period of time, by pressing air into a printing head which is constructed in an enclosing manner. CONSTITUTION:A printing head 10, which is constructed to an enclosed structure, and a pump 15 are connected with a connecting pipe 12 for installation on  a moving table 18.

Title: Helium leak-testing apparatus
Inventor: OKAMOTO HIDEKI
IPC: G01M3/20
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To improve efficiency and accuracy in leak tests by temporarily interrupting roughing of a chamber, introducing the air, then resuming the roughing, thereby flushing helium remaining in the chamber by some reason other then a leak. SOLUTION: A CPU 71 of a microcomputer system 7 constituting a roughing line from a chamber 2 to a discharge means 3 controls to close a first discharge valve BV in the middle of roughing, interrupts the roughing once and opens a leak valve LV. While the air is still discharged to a mass-analyzing part 1, a leak line is constituted to vent the air through an air-releasing part to the chamber 2. Thereafter, the leak valve LV is closed and the discharge valve BV is opened. The apparatus is returned to the discharge state and resumes the roughing by the discharge means 3. A flushing action is thus effected to an inner wall of the chamber 2 and a surface of a work W, and helium is diffused in the chamber. Accordingly, the helium is effectively discharged outside the chamber 2 through the discharge means 3, enabling effective leak tests.

Title: Terminal cap for covered conductor
Inventor: TAKAMOTO TAKEJI
IPC: H01B17/56
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the operability for waterproofing the terminal of a covered conductor. SOLUTION: A plurality of ring-shaped projections 13 are formed on the inner peripheral surface of a bottomed cylinder 12 at intervals along the direction of the axis of the cylinder. The ring-shaped projections 13 get smaller in bore so that the deeper one has a smaller bore. A terminal cap is made of elastic rubber or plastics. When the terminal cap 11 is put over the terminal of a covered conductor 2, either of the projections 13 undergoes elastic deformation and makes intimate contact with the outer peripheral surface of the covered conductor 2. Therefore, the terminal cap 11 is simultaneously secured to the covered conductor 2 and prevents entrance of water. This can be achieved simply by putting the terminal cap over the wire terminal, without the need for vinyl tape, etc.  The terminal cap can be used also for covered conductors of different outside diameters within the range of the bore of the projection 13.
