Title: Production of thiophene derivative and novel dihydrothiophene 1-oxide
Inventor: ROOBERUTO RIPERU
IPC: C07D333/48
Filed: 1989-02-15
Abstract: Thiophene derivatives with an optionally substituted amino group on the thiophene ring are prepared by dehydrogenation of dihydrothiophenes which are substituted in the same manner as the desired thiophene derivatives, using H2O2, the dihydrothiophenes being reacted in a first reaction step with H2O2 in neutral medium to give the corresponding sulphoxides, and, in the second reaction step, these are then rearranged with acid to give the thiophene derivatives. The dihydrothiophene-1-oxides which are formed in this process as intermediates are novel compounds. They, and equally the thiophene derivatives obtained from them by rearrangement with acid, are intermediates mainly in the crop protection agent sector and pharmaceutical sector.

Filed: 1986-02-20
Abstract: PURPOSE:To easily perform the adjustment of the forward characteristics and the backward characteristics by adjusting the ratio of the contact areas of both metal layers to a semiconductor substrate to the prescribed ratio. CONSTITUTION:An oxide film (SiO2 film) 2 is adhered on an Si substrate 1 and after the central part of the film 2 is removed, a first barrier metal layer 4 is formed by evaporating Mos in a lattice type by a mask evaporation.

When the ratio of the contact area of the Tis having the phiB of 0.48V to the Si substrate is made larger, the forward rise voltage becomes smaller and when the ratio of the contact area of the Mos having the phiB of 0.67V to the Si substrate is made larger, the rise voltage becomes larger. Reversely, the backward leakage current is increased as the ratio of the contact area of the Tis becomes larger, and is decreased when the ratio of the contact area of the Mos becomes larger.

Abstract: PURPOSE: To prevent plastic burr at the border part of an exposed surface and a sealing plastic by surrounding a surrounding wall by providing fixed intervals between the exposed surface and the inside circumference part of the cavity formed at the part attached to the lower part of a heat sink.  
     CONSTITUTION: A sealing plastic 9 injected from an injecting hole 8 is filled up in a cavity 7 and is injected into a cavity part 10 through an injection hole 11. The plastic 9 passed the injecting hole 11 is divided into a surrounding grooves 10a and a center part 10b by surrounding walls 14 and the space between the lower part 2b of a heat sink 2 and the surrounding walls 14 is narrowly provided like the space H, so the sealing plastic 9 will be filled up in the surrounding grooves 10a and then in the center part 10b. Therefore, the air is concentrated on the vicinity of the center part of the lower surface 2b and the plastics 9d, 9e filled up in the center part 10b will easily be stripped and eliminated from the lower surface 2b by lightly applying external force. A that time, the adjoining part at the border of the lower surface 2b and the plastic 9 is not completely filled up by the plastic 9d. So plastic burr will not cause.
