Title: Method and apparatus for descaling
Inventor: SUKEGAWA KAZUYA
IPC: B21B45/08
Filed: 1982-07-26
Abstract: PURPOSE:To remove oxidized scales generated on the surface of band steel material with saving energy, by jetting compressed air mixed with water on the surface of the band steel material. CONSTITUTION:When the tip end of a band steel 15 to be descaled comes near to a header 8, a solenoid valve 23 is opened and compressed air from an air compressor 20 (air source in the plant) is supplied to a mixer 19. At the same time, a part of the compressed air passed through the solenoid valve 23 for changing over air actuates a switch valve 18 to open side to open it. Consequently, water from a water supply pump 17 is supplied to the mixer 19 through a stop valve 3 and the valve 18. In the mixer 19, water is mixed with the compressed air that flows in the piping at high speed and jetted on the surface of the band steel 15 from a nozzle 7 of the header 8. The surface temperature of the band steel is lowered by water and air, thus forming the countless cracks in the scales on the surface, and the scales are stripped off. At the same time, compressed air blows off stripped scales. Thus, descaling is performed.

Title: Pulse voltage generating circuit
Inventor: IZAKI NAOYUKI
IPC: H03K3/282
Filed: 1982-07-26
Abstract: PURPOSE:To attain a quick rising response with low power consumption by adopting a Darlington form for a constant current circuit section. CONSTITUTION:A Darlington circuit 30 is used for the 1st constant current circuit 1 connected in series between a power supply voltage and a ground level, the 2nd constant current circuit 2, and the 1st constant current circuit of a pulse voltage generating circuit provided with a buffer circuit 3 to a connecting point of the 1st and the 2nd constant current circuits 1, 2, so as to attain high-speed rising response. The adoption of the Darlington connection permits a large current to flow only for a short time when an output rises and to suppress the current to a value determined with the circuit 2 for the steady state. Thus, the rising response is quickened with low power consumption. Since the current is less than that of an output stage, the current amplification factor is increased and the area of the elements is reduced.

Title: Refreshing control system
Inventor: TOOYAMA OSAMU
IPC: G11C11/34
Filed: 1983-07-15
Abstract: PURPOSE:To shorten a refreshing wait time by performing refreshing operation successively plural times as predetermined. CONSTITUTION:When an execution signal is impressed from a successive refreshing control signal 3, a refreshing monitor register 11 outputs an internal refreshing signal 12. Then, a refreshing operation instruction 9 is outputted from a refreshing execution control register 8 to refresh after a refreshing operation wait time is elapsed. When the refreshing operation is completed, a control part 3 outputs a refreshing address carry-up signal 4 and the register 8 outputs the next instruction to perform successive refreshing operation; when the refreshing operation is performed as many time as predetermined, i.e. four times, the signal 12 is reset. Therefore, the refreshing operation is carried out plural times in only a wait time for signal operation and the refreshing wait time is shortened substantially.

Abstract: PURPOSE: To make a mercury coating device adaptable for a high speed automated equipment with a reduced variance of rolling distance of mercury grains by means of a mercury grain damping section comprising a convex or concave line 15 or 14 linked with the rim of a through hole provided on the inner surface of a funnel- shaped body of the device.  
     CONSTITUTION: An inclined surface inside a funnel-shaped body which is adapted to feed mercury in drops coated with an inert powder from a mercury gauge to an exhaust head is provided with a mercury grain damping section comprising a convex or concave line 15 or 14 linked with the rim of a through hole. The convex or concave line 15 or 14 is positioned close to the through hole 7 excluding the point where the mercury is trickling down. Such an arrangement, with the rotation of the funnel-shaped body 12, the mercury drops thus trickling down are spirally rolling along a powder layer 9 made of zirconia or the like while such a spiral motion of the drops is blocked against the convex or concave line 15 or 14. This checks a dense spiral rotation around the through hole 7 thereby minimizing the variance of the rolling distance.

IPC: H03K19/177
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a circuit monitoring method which can deal with restriction relevant to the size of a circuit board and carry out more flexible signal monitoring. SOLUTION: At the time when a signal applied to a circuit 18i in the inside of an ICi, of which the inner circuit can be programmed, such as FPGA(a field programmable gate array) is monitored through a test point TPi, of input and output terminals of the ICi, empty terminals 28i which are not used at that time are used. As compared with the case that test points are set corresponding to the input and output terminals of respective IC, the number of the test points is lessened. Moreover, since the ICi has the programmable inner circuit IC, the IC is utilized and the inner circuit 30i to connect an empty 28i and an object circuit 18i to be monitored is re-programmed based on the necessity.  Though the number of the empty terminals 28i is small as compared with the numbers of the input terminals 24i and the output terminals 26i utilized at that time, of signals sent to the object circuit 18i to be monitored, all of the signals to be monitored can be monitored responding to the necessity.

Title: Optical recording and reproducing apparatus
Inventor: MORITA HIDEJI
IPC: G11B7/139
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To stably reproduce a CD using an objective lens designed for a high density disk without any influence of shift of the objective lens. SOLUTION: A masking member 11 is provided on an objective lens 5. On the occasion of reproducing a CD which has a substrate thicker than a high density disk using the objective lens 5 designed for high density disk 1, this masking member 11 reduces the number of effective numerical apertures NA of the objective lens to remarkably reduce influence of aberration. Thereby, even if the objective lens 5, for example, is shifted, since the masking member 11 follows such shift, an optical spot of the adequate size is formed on the signal surface of the high density disk 1 or CD. Particularly, on the signal surface of CD, the optical spot of the adequate size is formed by means of the optical flux which passes through the internal side of the masking member 11 and has comparatively less amount of aberration.
