Title: Welding wire supplying device and method therefor
Inventor: KAWAMURA KENJI
IPC: B23K9/12
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent a generation of buckling on a welding wire between a push motor side which supplies a welding wire rewound from a welding wire coil, and a pull motor side which receives the wire and send it to a welding torch. SOLUTION: An air is supplied at a given pressure to an air motor which rotary drives a roller to push a welding wire pulled out from the welding wire coil 4 into one end of the wire inserting pipe 3. An electric motor 6m rotary drives the rollers to take out the welding wire pushed into the wire insertion pipe 3 at the other end of the wire insertion pipe and transfer it to the torch Tw.

Title: Optical wave distance measuring instrument
Inventor: KAWAKITA TADAHIRO
IPC: G01S17/36
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To shorten time required for distance measurement by measuring distances at a first distance measurement while sequentially switching all frequencies, measuring distances at a second distance measurement or later at frequencies of the first frequency or higher, omitting distance measurement at frequencies of the first frequency or lower, and using previously measured values. SOLUTION: An arithmetic unit 1 outputs a switching signal S10 of modulation signals from a first frequency to a fourth frequency, and distance data corresponding to each frequency converted from a phase difference measured by the fourth frequency is obtained. Then, by adding distance data corresponding to each frequency, the distance to a reflecting mirror 21 of a target object is obtained. In addition, the arithmetic unit 1 corrects measured distances from the difference between the measured distance of an external optical path 22 and the distance of a reference optical path passing through an internal optical fiber 20. In distance measurement over a plurality of times, the distance measurement through the use of all modulation signals from the first frequency to the fourth frequency is performed at the first distance measurement.  Measurement only by the first frequency is performed at the second distance measurement or later, and distance measurement is performed through the use of previously measured values for measured values corresponding to the second to fourth frequencies. Therefore, it is possible to shorten the overall time required for distance measurement by a great amount with accuracy as high as at the time of using all the frequencies.

Title: Latent heat recovery water heater
Inventor: KOSHIMIZU DAISUKE
IPC: F24H1/14
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To suppress lowering of precision when complicated control of a supply hot water temperature is executed in a latent heat recovery hot water supply apparatus. SOLUTION: A water heater (1) is provided with a neutralizing device (3) to mix city water flowing through a branch pipe (11) branched from a supply water pipe (9) to neutralize drain. A flow rate sensor (25) is situated in the portion, of the supply water pipe (9) situated upper stream and extending to a heat-exchanger (4), and detects a flow rate of city water. A supply hot water temperature control device (21) controls a supply hot water temperature by using a detected value. Since the branch position of the branch pipe 11 is situated upper stream from a position where the flow rate sensor (25) is situated, a detecting value is a value in a spot where a change hardly occurs after an influence by branching is exercised.

Filed: 1989-12-15
Abstract: PURPOSE: To efficiently perform access from an input/output device to a main storage device by performing access from the input/output device through an input/output cache to the main storage device. CONSTITUTION: A computer system is provided with a central processing unit (CPU) 12, a main storage device 20 and input/output devices 48 and 50. There is an input/output cache 30 between the input/output devices 48 and 50 and the main storage device 20, and the access from the input/output devices 48 and 50 to the main storage device 20 is performed through the cache 30 at all times. When performing access from the CPU 12 to the main storage device 20 which can be accessed by the input/output devices 48 and 50 as well, such access is performed through the input/output cache 30. Thus, the input/output devices 48 and 50 can efficiently access the main storage device 20. In this case, since the CPU 12 performs memory access to a shared memory 28 through the input/output cache 30 at all times, no problem concerning the consistency of cache occurs between a CPU cache 14 and the input/output cache 30.

Title: Device for permanently binding bundle of documents and method for binding bundle of documents using the device
Inventor: HABIERU BUSUKETSUTO FUONTOHIBE
IPC: B42B5/08
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To permanently bind a sheaf of paper through uniting pieces of paper by inserting a rod into a hole opened in a sheaf of paper and pushing the rod down until its stopper comes into contact with the upper face of the paper and further, forcing a sleeve onto the rod from the tip thereof to cut the tip of the rod. SOLUTION: A designated hole 12 is already opened in a sheaf of paper 13. When a rod 1 is inserted into the hole 12, a stopper 2 comes into contact with the upper face of the sheaf of paper 13 near the hole 12. Next, the stopper 5 of a sleeve 4 inserted along the rod 1 comes into contact with the lower side of the sheaf of paper 13. In this case, a rim 6 slipping on the rod 1 is partially forced into the rod 1 so that the rod 1 cannot be pulled out by a forcing action. Next, the rod 1 is cut flush with the stopper 5. Thus it is possible to certainly bind the sheaf of paper 13 in a rapid and effective manner and thereby ensure high use convenience.

Filed: 1994-12-27
Abstract: PURPOSE: To realize high speed picture reading by automatically selecting control for monitoring signals which a position detection means outputs at every one pulse period of the excitation phase switching of a pulse motor or at every plural pulse periods in accordance with a drive condition at that time and switching an excitation pattern at high speed. CONSTITUTION: Since an HP (home position) operation is not executed immediately after power is turned on, the HP operation is initialized. A system is changed from a macro interruption processing to a regular interruption processing by the switching of an interruption mode. Then, motor excitation pattern interruption is inhibited. A timer value (motor pattern switching period) for a homing operation is set in a timer, 14 is set in a scanner status, and the timer is started. When the timer is timed up, a motor excitation timer interruption request is generated and the processing is executed. In the processing, control for monitoring the signal which the position detection means outputs at every pulse period or plural periods of the excitation phase switching of the pulse motor is automatically selected in accordance with the driving condition at that time.
