Title: Electrode for resistance welding
Inventor: HANEDA OKITOSHI
IPC: B23K11/30
Filed: 1994-05-24
Abstract: PURPOSE:To lessen a change in the area at which the front end of an electrode comes into contact with a material to be welded and to suppress excess degradation in current density by gradually expanding the sectional area orthogonal with the axial direction of the electrode toward the inner side from the front end and gradually expanding the area of a hole bored in the central part toward the inner side from the front end. CONSTITUTION:A convergent taper 12a is formed it the front end 12 of an electrode body 11. Namely, the diameter is gradually expanded toward the inner side from the front end. The front end 12 is bored with the hole 13 made larger in the diameter toward the inner side. The taper 13a larger toward the inner side is formed therein. Namely, the diameter of the hole 13 is made gradually larger toward the inner side from the front end. Then, the hole diameter is gradually expanded even if the front end 12 is worn and the diameter is gradually expanded by intermittent use and, therefore, the substantial increase rate of the contact area is not so much and the execussive degradation in the current density is suppressed. Welding conditions are stabilized and the life thereof is greatly prolonged.

Abstract: PURPOSE:To stabilize passing of a steel strip and compact a looper for a thick plate by deciding a drum diameter as small as possible in accordance with an elasto-plastic bending stress area of a steel strip and providing a guide and a spring up suppressing roll on the back of the drum. CONSTITUTION:The steel strip 1 is reversed at a loop car drum 3, coiled forcedly by guide rolls 4 on a drum 3, pressed by a holding roll 12 so that it is not brought into contact with the ceiling of a pit and then guided to a tube manufacturing equipment. Many guide rolls 4 are supported by a frame 11 and the holding roll 12 is supported freely rotatably by frame 13. The loop car gives a tension to the steel strip through a wire 2 engaged with a bracket 8 installed on a frame 7 and by pulling a loop car traveled by a wheel 9 on a rail 10 through a winch. Plastic deformation is generated on the steel strip and makes so called coiling tendency but tends to be corrected on the succeeding stage. Further, a bend in time of tube manufacturing is generated in the direction orthogonal to this direction, consequently, is not influenced by the winding tendency.

Title: Printer controller
Inventor: MONNO TAKASHI
IPC: H04N1/36
Filed: 1990-04-25
Abstract: PURPOSE:To obtain the printer controller to synchronize with a picture by a CPU by providing a reading means to read out a data, which is written into a line buffer, within the data holding time of a DRAM corresponding to a horizontal synchronizing signal from a printing part. CONSTITUTION:The line buffer uses a FIFO memory 41. The read side and write side of this memory 41 are asynchronously operated, and address signals are generated on the inside. Therefore, it is not necessary for the memory 41 to generate the address signals when performing access. For the FIFO 41 composed of the DRAM, each unit to store the data is equipped with a capacitor and stores the information according to the presence/absence of electric charges accumulated in this capacitor. It is necessary to charge again the electric charge within prescribed time, and it is enough to output the data written into the memory 41 within the specified time. Therefore, when detecting write control timing, the data for one line are immediately written into the memory 41 on the write side and the memory 41 is read out corresponding to the synchronizing signal from the printer on the read side.

Filed: 1984-05-31
Abstract: PURPOSE:To use a high-speed digital circuit efficiently in common to wide-band calls and narrow-band calls by employing two-story constitution for the exchange processing of wide-band calls. CONSTITUTION:Communication with a corresponding terminal within the same station is carried out through a corresponding exchange function without any discrimination between a narrow-band and a wide-band call. When there are a narrow-band and a wide-band call from the outside of the station, the narrow- band call is sent to a demultiplexing function part 3 and the wide-band call is divided by a separation part 7, equalized in speed to the demultiplexed narrow- band call, and sent to the demultiplexing function part 3. Consequently, both band calls are multiplexed smoothly and the multiplexed wide-band and narrow- band call is sent out to a trunk line 8. The wide-band and narrow-band call sent from an external station through the trunk line 8 is demultiplexed by the demultiplexing function part 3 informed of the transmission through a narrow- band call multiplex incoming line 9, so that the narrow-band call is passed to an exchange function part 2 and the wide-band call is sent to an exchange function part 10.

Filed: 1986-05-15
Abstract: PURPOSE:To form a resistor easily with excellent controllability by shaping the silicide layer of a transition metal as the resistor formed by the interface reaction of an amorphous silicon layer or an amorphous silicon compound layer and a transition metal layer. CONSTITUTION:An amorphous silicon hydride layer 2 is deposited on a predetermined substrate 1, and a chromium layer 3 is shaped selectively only in regions 3a as electrodes and a region 36 as a resistor through a sputtering method using a metallic mask to the upper layer of the layer 2. Lastly, the chromium layer on another region, the region 3b as the resistor, is removed through etching, leaving the chromium layers 3 only in the regions 3a as the electrodes through a photolithographic method. A chromium silicide layer formed by the interface reaction of the chromium layer and the amorphous silicon layer remains in the region as the resistor at that time, and the chromium silicide layer functions as a resistance layer R1. Accordingly, the desired resistance layer can be acquired extremely easily.

Filed: 1980-08-12
Abstract: PURPOSE:To quickly shift an engine to safe side when output from knock detection circuit is intercepted by troubles like lead wire breakage etc. by organizing retard angle control to bring ignition timing to a delayed position from knocking area. CONSTITUTION:Knock detection circuit 1 judges knocking volume from output of knock sensor 19 and issues output voltage V01 to meet the said knocking. Retard angle setting circuit 2 defines the retard angle to conform with the above output V01 and outputs on the ignition circuit 3, which, in turn, taking in the detective signal from distributor 14, makes out ignition signal delayed for the above mentioned retard angle and outputs on the ignition section 20. With this system, the retard angle detection circuit 2 is composed including retard angle setting section 23, thus is capable to detect a wire breakage by sensing variation of electric current i11 which is charged on terminal 11 at the breakage of lead wire 4. In this way, it outputs a certain fixed angle retard signal at an ignition time delayed position from the knocking area.

Filed: 1981-07-16
Abstract: PURPOSE:To countervail pressures at discharge and suction sides by forming each intermediate chamber between a plurality of Wesco pump and opposing the suction port of every intermediate chamber to the discharge port of preceding casing, and the dischare port thereof to the suction port of a subsequent casing. CONSTITUTION:Each intermediate chamber 17 is formed between a plurality of Wesco pumps 13, 14. Suction ports 7b, 8c and discharge ports 7c, 8d of respective Wesco pumps 13, 14 are arranged at an angle which is fond by such equations as (each circumference angle/the number of wesco pump)=360 deg./2=180 deg.. The suction port 7b of each Wesco pump 13 is in opposed communication with the discharge port 7d of each Wesco pump 14, while an intermediate chamber 17 is interposed between the pumps. Since discharge and suction pressures produced in each Wesco pump are countervailed, the multi-stage Wesco pump may be less apt to be damaged and the life is therefore prolonged.
