Filed: 1986-05-14
Abstract: PURPOSE:To make a snubber circuit compact, by a method wherein one of the snubber circuit is constituted so as to absorb overvoltage of the whole, and other is constituted so as to absorb overvoltage applied to the element. CONSTITUTION:Three-phase power source U, V, W is controlled by arm constitution elements U<+>, U<->, V<+>, V<->, W<+>, W<->, and supplied through a series reactor Ld to a load LL. A capacitor Cf is constituted by a smoothing capacitor, and the constituent element U<+> is composed of a first snubber circuit comprising a transistor UTr<+>, a diode UD<+>, a snubber capacitor Ct and a snubber resistor Rt, and of a second snubber circuit comprising a snubber capacitor Cd and a snubber resistor Rd. Overvoltage at cutoff state of the transistor UTr<+> is absorbed by the first snubber circuit. Reverse voltage generated at power source commutation and applied to the diode UD is absorbed by the second snubber circuit. Since the second snubber circuit may absorb the overvoltage by inductance component of wiring around the diode, it can be made compact.

Title: Thin film magnetic head
Inventor: OKAWA GENICHI
IPC: G11B5/31

Abstract: PURPOSE:To prevent a depth measuring error which follows a size displacement of a marker, by providing a pair of triangle-shaped markers which have been provided in parallel by displacing each apex position by 180 deg. against an equal depth line. CONSTITUTION:A core 11 and a marker part 12 are formed on a substrate 10. As for this marker part 12, a pair of triangle-shaped markers 14, 15 are formed by a thin film by displacing each apex position by 180 deg. so as to corre spond to an equal depth line 13. When widths to the line 13 of each depth d1, d2 of the markers 14, 15, the base and the height are denoted as W1, W2, and D, and L, respectively, an average value (d) of the depth d1, d2 is derived as d=L/2{1+(W2-W1)/D}. As for the markers 14, 15, even if its widths are displaced by DELTAW1 and DELTAW2 by a processing process after the thin film has been formed, the errors DELTAW1, DELTAW2 become roughly constant, therefore, no influence is exerted on said (d). Accordingly, by measuring the widths W1, W2 of the markers 14, 15 and polishing a depth terminal, an adverse influence which follows a size displacement of the markers 14, 15 is eliminated, and the depth accuracy can be improved.

Title: Moisture-proof container sealed by own weight
Inventor: FUJITA HIDEO
IPC: B65D47/06
Filed: 1994-04-11
Abstract: PURPOSE:To prevent moisture from entering a container without any operation before and after use by sealing a seasoning exit with a synthetic rubber packing and a plastic ball constantly by an own weight of the container and seasoning and sealing a slit of a shaft with bellows. CONSTITUTION:When a container is picked up, a total weight of a bottom plate 10, a shaft 1, bellows 2 and a plastic ball 4 makes a distance between a synthetic rubber packing 3 and a plastic ball 4. When the container is put upside down, seasoning may come out of an exit hole with the distance maintained by a coil spring 8. When the container is returned to a normal posture thereafter, the seasoning which has come near the exit hole drops in the container body. When the container is put on a table or the like, the weight of the container body 6 and the seasoning is applied to the plastic ball 4 to have them sealed. Therefore no operation for preventing moisture from entering the container is necessary, wherein the more the seasoning, the heavier the whole container, thereby increasing sealability.

Filed: 1980-08-07
Abstract: PURPOSE: To obtain the optimum recording exposure conditions, by reproducing the previously recorded address signal on a guide track provided to an information carrier and controlling the laser output with the reproduced address signal.  
     CONSTITUTION: An address signal SI is separated by a signal separating circuit 34 from signals SAWSD received a photoelectric conversion through a photodetector 17. The signal SI is a code signal modulated by a PE or an MFM and demodulated by the clock supplied from a clock reproducing circuit 37 through an address signal reproducing circuit 36. A modulated series address signal (a) is stored in a series- parallel converting circuit 38 and turned into an analog signal through a D/A converting circuit 39 to be applied to a laser driving circuit 35 through a bias switching circuit 40. Thus the bias current of a semiconductor laser 3 is controlled. As a result, a proper laser output is ensured although the speed is different between the inner and outer circumferences of an information carrier 1.

Abstract: PURPOSE:To improve the leading characteristics of arithmetic with a small hardware quantity by processing accesses in parallel with each other to both arrays from a time point when no bank conflict occurs when an equal bank width at every machine cycle is obtained. CONSTITUTION:The start address of the 1st array data is set to a register 10 through an input signal line 100; while the start address of the 2nd array data is set to a register 11 via an input signal line 101 respectively.
