Title: Press brake
Inventor: OKUBO YASUMI
IPC: B21D5/02
Filed: 1992-08-18
Abstract: PURPOSE:To provide a press brake by which the superior bending is attained by compensating the change of the lower limit position caused by temperature change and pressurizing force difference of hydraulic oil. CONSTITUTION:A work W is bent by relatively moving an upper die (one metallic die) 19 freely attachably/detachably provided on a ram 17 which is freely vertically moving by a hydraulic circuit and a lower die (another metallic die) 13 freely attachable/detachable provided on a frame (main body of the press brake) 3. A lower limit positioning valve (limitation positioning valve) 27 by which the hydraulic circuit is controlled is provided on the frame 3 to limit the amount of stroke of the ram 17 when the upper and lower dies 19 and 13 get near each other and an extention shaft (dog) 87 whose vertical position is freely adjusted by a compensating unit 55 is provided on the ram 17. Thus, since the minimum distance between the upper and lower dies 19 and 13 is fixed, the bending having a fixed angle is uniformly executed.

Title: Linear image sensor and its driving method
Inventor: YAMAMOTO YASUNAGA
IPC: H04N5/378
Filed: 1988-09-01
Abstract: PURPOSE:To reduce an after image by performing refresh sufficiently by performing supplementary charge simultaneously on all image elements in an N-th block after completing access to the image elements in the N-th block. CONSTITUTION:An image element string consists of N blocks in total setting every M image elements as one block, and consists of total (MXN) image elements. A scanning circuit 4, after the read of all image elements of each block being completed, generates a pulse to make access for the refresh of all image elements in the block for a certain constant period. After the access to the image elements in the N-th block is completed sequentially, the supplementary charge for the complete refresh of all image elements in the N-th block is performed for a constant period, and after that, the image elements in an (N+1)-th block are accessed sequentially. In such a way, it is possible to quite easily realize a linear image sensor with low after image even at the time of performing fast reading.

Title: Control and extinction methods of secondary flame in rocket and device thereof
Inventor: MITANI TOORU
IPC: F02K9/00
Filed: 1983-11-21
Abstract: PURPOSE:To control a secondary flame in an efficient manner, by emitting and mixing a combustion inhibitor in and around a nozzle skirt outlet end where exhaust gas of a rocket and the atmosphere are contacted with each other, while leading the combustion inhibitor into the peripheral part of an exhaust gas stream. CONSTITUTION:A gaseous combustion inhibitor is stored in a tank 3 and emitted to a peripheral part of an exhaust gas stream 6 being high in temperature and including unburnt fuel from a combustion controlling nozzle 5 being annularly installed in and around an outlet end 2 of a nozzle skirt 1 by way of a control valve 4. Here, at a region 9 where the gas stream 6 and an air stream 8 are mixed, usually an oxidizing exothermic reaction occurs most actively and a secondary flame is made up there. And, this region is one where thickness of the combustion flame is efficiently controlled and finally extingushed. Thus, since the combustion inhibitor is not added to a solid propellant, problems on a drop in combustion capacity or physical properties and manufacturing the propellant all can be solved.

Title: Circuit and device for driving actuator
Inventor: KAWABE KOTARO
IPC: H02N2/06
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To quiet beating sounds by setting the frequency of power supply noise in a specific range which is periodically produced from a drive voltage generating means and superposed upon the drive voltage generated from the generating means, and the frequency of drive pulse signals. SOLUTION: Since power supply noise is produced at rising of a synchronizing pulse signal VSYNC, the frequency of the power supply noise becomes equal to that of the signal VSYNC, and a spike voltage appears in a drive pulse signal due to the power supply noise appearing on an output line connected to the cathode of a diode D. When two waves are combined, beat sounds are produced due to the interference between the waves. A CPU 3 sets a switching frequency f2 of a transistor Q so that the relation between a frequency f1 of the drive pulse signal and a frequency f2 becomes such that 4,000<|m.f1-n.f2|, where m and n respectively represent positive integers which are smaller than a prescribed value. Therefore, an actuator drive circuit can be quieted, because the beat frequency becomes hard to be heard is by human ears.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/72
Filed: 1984-10-19
Abstract: PURPOSE:To improve durability in high-speed sliding contact with an alloy head by constituting a thin ferromagnetic film of pulverous crystal particles having holes and specifying the porosity thereof with a volume ratio. CONSTITUTION:The production of a magnetic recording medium is executed by subjecting a high-polymer substrate to vacuum drying, then using helium as a replacing gas, adsorbing the gas to the substrate to the saturation, using such substrate and forming a magnetic recording layer thereon by an electron beam vacuum deposition method, sputtering method, etc. The helium is then trapped in the pulverous crystal. The trapped gaseous helium is expelled by heating the substrate for a long period in a vacuum after the formation of the magnetic recording layer. The porosity in the pulverous crystal particles in this case is controlled from 3% to 15% in vol%, by which the time to the eventual breakdown of the magnetic recording layer as a result of the frictional grazes generated during the high-speed sliding contact with the alloy head is considerably extended.
