Inventor: YAMAMOTO SHINJIROU
IPC: C07D495/04
Filed: 1982-07-21
Abstract: NEW MATERIAL:The compound of formula I (R1 and R2 are H or methyl at the same time or R1 is methyl and R2 is H; R3 is methyl or ethyl; R4 is alkyl or allyl; R5 is H, methyl or Cl; R6 is H or methyl) or its acid addition salt.

Title: Dropout inspection instrument
Inventor: NISHIWAKI SEIJI
IPC: G11B20/18
Filed: 1985-06-12
Abstract: PURPOSE:To discriminate whether dropout comes from a foreign material in a base or abnormality of a recording face by detecting respectively the luminous strength of two regions of a reflected light and obtaining its sum and difference signals. CONSTITUTION:The luminous strength of two regions divided by a straight light orthogonal to the optical axis in the reflected light reflected in the recording face 16 of an optical disc and collected by an aperture lens 14 is detected, the sum and difference signals are compared at their detection levels respectively and it is discriminated when they exceed both the detection level from when only the sum signal exceeds the detection level. While the effect due to foreign material in the base on the reflected light intensity distribution appears symmetrically with respect to the optical axis, since the effect due to a fault on the recording face has no symmetry, the amplitude of dropout of the foreign material in the base due to the difference signal is smaller than the dropout amplitude due to a fault on the recording face of the difference signal. Thus, whether the dropout comes from the foreign material in the base or the abnormality of the recording face is discriminated by comparing the dropout amplitudes in the difference signal at a proper detection level.

Abstract: PURPOSE:To improve power/mechanical conversion efficiency of an ultrasonic wave motor by forming a plurality of rows of groove rows along the moving direction of a moving element on the contacting boundary of a stator and the element, and mounting a vibration source on the side. CONSTITUTION:The stator 12 of an ultrasonic motor has outer groove row formed with 4 grooves 17 of grooves 17a-17d circumferentially with a motor shaft to become the axial center of a moving element as a coaxial center, and inner groove row formed with 4 grooves 18 of grooves l8a-18d.

Filed: 1990-05-19
Abstract: PURPOSE:To suppress the Barkhausen noises by the movement of the magnetic wall in a magneto-resistance effect element by disposing the magneto-resistance effect element in the gap of an electromagnet consisting of a ferromagnetic film and a coil and impressing the leaking magnetic field from the electromagnet to the easy axis direction of the element.

The static magnetic energy by the diamagnetic field in the MR element 11 is lowered by the magnetic field H from the electromagnet 20 impressed in the easy axis direction of the MR film and, therefore, the MR element 11 is made into the single magnetic domain structure free from the magnetic wall. Since there is no movement of the magnetic wall, the Barkhausen noises are suppressed.

Title: Semiconductor device
Inventor: SHIMIZU AKIHIRO
IPC: H01L29/78
Filed: 1987-05-27
Abstract: PURPOSE:To obtain a device, breakdown strength of which is increased and a short channel effect of which is inhibited, by separating a diffusion end at the time of the formation of a punch-through stopper layer from a gate end, further separating a diffusion end at the time of the formation of a high- concentration diffusion layer from the diffusion end of the punch-through stopper and diffusing the punch-through stopper layer up to the inside of a substrate. CONSTITUTION:Punch-through stopper layers 8 are diffused and shaped from a first sidewall spacer 4, and high-concentration diffusion layers 6 are diffused and formed from second sidewall spacers 5 successively shaped after the layers 8 are formed. When diffusion ends at the time of the formation of the P-pocket layers 8 are separated from gate electrode ends 3, the concentration of a substrate surface section as a channel just under a gate is not increased even in the large diffusion depth of the P-pocket layers 8. Accordingly, it is most excellent that the diffusion ends of the P-pocket layers 8 are parted from the gate electrode ends 3 and the high-concentration diffusion layers 6 are not separated. That is, when each parameter is shaped so as to satisfy r2<=r1+l1 and r3<l1+l2, the elevation of breakdown strength and the control of a short channel effect can be realized simultaneously.
