Title: Grinder
Inventor: KAMEI HIROMASA
IPC: B24B49/16
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To perform highly accurate grinding work by properly detecting grinding force regardless of a shape of a grinding object surface by reliably holding a grinding wheel, by measuring displacement of a plate material to receive work reaction of the grinding wheel, and finding the grinding force on the basis of its measured result. SOLUTION: In the grinder a grinding wheel 17 driven in rotation is pressed to a grinding object surface 52 of a welding padding bead 51. At this time, a laser displacement gauge 26 measures pressing reaction Fu acting on a tip part of the grinding wheel 17 as a deflection quantity of a detecting plate 22. As a result, the grinding wheel 17 is reliably held without vibrating it, and grinding force can be properly detected regardless of a shape of the grinding object surface 52. A control part 27 performs an operation on pressing force FD of the grinding wheel 17 to the grinding object surface 52 from a displacement quantity of the detecting plate 22, and highly accurate grinding work can be performed by controlling an electric motor 14 so that this pressing force FD becomes proper.

Filed: 1981-08-27
Abstract: PURPOSE:To judge furnace conditions precisely and to prevent slips by suspending wire rods attached with weights at the preceding ends into a blast furnace, bringing the same downward together with charging materials, measuring the lengths at which the wire rods extend into the furnace with time and detecting the change in the descending speed of the charging materials. CONSTITUTION:Conduits 4a, 4b, 4c are inserted into a blast furnace through its side wall 3, and the preceding ends thereof are located in the core, middle and wall parts of the furnace respectively. Wire rods 11a, 11b, 11c attached with weights 12a, 12b, 12c at the preceding ends are suspended through the respective conduits 4a-4c into the furnace and are brought down onto the surface of the charging material layer. Raw materials are charged to capture the rods 11a-11c into the layer 13 and to allow the wire rods to descend together with the layer 13. Since the rods 11a-11c extend into the furnace as time passes by, the extended lengths are detected by the revolutions of drums 14a, 14b, 14c, and the revolutions are converted to lengths and the lengths are indicated and recorded on an indicating recorder 15. If these lengths are measured continuously, the change of the descending speed of the layer 13 with time is detected continuously and the occurrence of slips is prevented.

Title: Ignition timing controller
Inventor: TAMAI HIDEFUMI
IPC: F02P5/153
Filed: 1982-07-31
Abstract: PURPOSE:To improve economization yet more in fuel consumption as well as to aim to upping an engine output, by detecting the knocking of each cylinder with one knock sensor alone, while controling the ignition timing of individual cylinders separately. CONSTITUTION:A knock sensor 1 is installed each in a proper position of an engine and its signal is discriminated by a knocking discrimination device 2. In this connection, a combustion cylinder discrimination device 6 counts ignition command signals and discriminates the cylinder that is in a combustion stroke. When knocking occurs, an ignition lag timing value correction device 3 addes a specified value to an ignition lag timing value (d) at that time and then corrects the holding value of an ignition lag timing value holding device 4. Therefore, the ignition timing of the next cylinder is delayed as long as the specified value to a reference ignition timing signal out of a distributor 7 by means of an ignition timing generating device 8. Also at this time, when knocking still occurs there, the specified value is further added, thereby increasing the lag timing value as much as the amount added.

Title: Wiper device
Inventor: TERABAYASHI GOSAKU
IPC: B60S1/08
Filed: 1981-08-28
Abstract: PURPOSE:To prevent a bothersome operation of a wiper and upgrade the safety of operation by making said wiper to perform a non-intermittent operation when wiper intermittent operation time is below a specified value, and an intermittent operation when the intermittent is above a specified value. CONSTITUTION:When a mode dial 12 for a wiper switch 10 is set to an INT mode, a wiper makes an intermittent motion and the intermittent time is continuously adjusted by the rotary operation of an INT dial 14. In an other word, when the INT dial 14 is moved round from the maximum position on SLOW side where the intermittent time of a wiper is a maximum value, t1 to FAST side, intermittent time ''t'' is continuously decreased. When a dialed position exceeds S2, the operation of a wiper is shifted from intermittent motion with time to non-intermittent motion where intermittent time is 0. On the contrary, when the INT dial 14 is moved round from the FAST side to the SLOW side beyond the position of S3, the wiper is shifted from non-intermittent motion to intermittent motion.
