Title: Production of fine particle of vinyl chloride resin
Inventor: ISHIMATSU HIROSHI
IPC: C08F14/00
Filed: 1992-12-03
Abstract: PURPOSE:To obtain the title particles having no skin layer and improved in processibility, etc., by mixing a specific compd. into a vinyl chloride resin having a specified particle diameter and obtd. by an aq. suspension polymn. and subjecting the resulting mixture to shear fracture under controlled temp., shear stress, and kneading time. CONSTITUTION:100 pts.wt. vinyl chloride resin obtd. by the aq. suspension polymn. of vinyl chloride and having a particle size of 30-200mum is mixed with 0.1-10 pts.wt. compd. having a solubility parameter of 9.1-10.5 and an m.p. of 130 deg.C or lower (e. g. stearic acid). The resulting mixture is subjected to a mechanical shear fracture at a resin temp. of 105-130 deg.C under a shear stress of 0.5X10<8>-5X10<8>dyn/cm<2> for a kneading time of 0.5-2min, giving the title particles having particle diameters of 0.1-2mum. Since skin layers of the original particles are broken and removed in the above pulverizing process, the resulting particles have a good miscibility with additives, such as a stabilizer, a lubricant, and a filler, and a good thermal stability.

Abstract: PURPOSE:To set a high frequency coil at an arbitrary position corresponding to an imaging region without applying load to an examine by arranging the high frequency coil to a bed so as to surround the top plate and the examine thereon and supporting the same in a state movable along the longitudinal direction of the top plate. CONSTITUTION:The high frequency pulse outputted from a high frequency oscillator 17 is modulated in its amplitude according to the order of a sequencer 12 by a modulator 18 and amplified by a high frequency amplifier 19 to be supplied to a high frequency coil 20a while an examine 1 is irradiated with an electromagnetic wave. The high frequency coils 20a, 20b on the sides of transmission and reception, and an inclined magnetic field coil 21 are arranged in the magnetic field space of the static magnetic field generating magnet 10 arranged around the examine 1. Normally, the coil upper side 29a is detached and the coil lower side 29b is hidden under an auxiliary top plate 32 and, when the examine 1 lies down on the auxiliary top plate 32, he can not look the coils and feels no excessive anxiety. The coil upper said 29a is connected to the coil lower side 29b from the part above the examine 1 by a connector 30.

Title: Method for controlling pulse duration modulation of three-phase inverter
Inventor: UMEZAWA KAZUYOSHI
IPC: H02M7/48
Filed: 1992-12-04
Abstract: PURPOSE:To eliminate the influence of a load power factor, and to stabilize control by switching the decision of too phases to be controlled every pi/3 in a method for controlling pulse duration modulation of a three-phase inverter in which the absolute values of PWM pulses are compared with each other for each phase, and two phases to be controlled are decided by two pulses having a large phase, while the one remaining phase is clamped. CONSTITUTION:D.C. power from a D.C power supply 2 is converted into A.C. power by on-off operations of a switching element that constitutes a three-phase inverter 3, and the A.C. power thus converted is supplied to a load 5 via an LC filter 4. An oscillator is disposed in an inverter control circuit 20 for deciding an electrical angle of each phase. The absolute values of PWM pulses are compared with each other for each phase, and two phases to be controlled are decided by two pulses having a large phase every pi/3, while the one remaining phase is clamped. Thus, the influence of a load power factor is eliminated, and a phase difference between output voltage instruction signals UR, US and UT and a clamp signal C is maintained at zero. As a result of this, distortion of an output voltage of the inverter is reduced, and also stable control becomes possible.

Title: Semiconductor device
Inventor: HASEGAWA SHIGERU
IPC: H01L29/78
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To improve the breakdown voltage of an insulated gate semiconductor device when the current supply to the device is interrupted by changing the shapes of patterns in an N-type source area and a P-type base area at the central and peripheral parts of an effective element area. SOLUTION: The ratio of the contacting area between a cathode electrode 10 and a P-type base area 3 to the contact area between the electrode 10 and an N-type source area 4 in the peripheral section of an effective element area is made larger than that at the central part of the effective element area. When channel conduction is made, the density of Halls accumulated in an N-type base layer 2 becomes larger and the electron injecting efficiency into the layer 2 also become larger at the central part of the effective element area, because the Halls are discharged to the cathode electrode 10 from the P-type base area 3 through a contact hole 13. On the other hand, the density of the Halls accumulated in the layer 2 becomes lower and the electron injection efficiency into the layer 2 also becomes lower in the peripheral part of the effective element area.
