Title: Manufacture of semiconductor device
Inventor: OYA AKIRA
IPC: H01S5/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent the angular deviation of a shadow mask due to vibrations and the cracking of a substrate due to thermal expansion by holding the shadow mask on the substrate by putting a projecting section provided on either one of the upper surface of the substrate or lower surface of the shadow mask into the recessed section on the other one. SOLUTION: One each linear projecting section 2 which has a normal mesa- like cross section, a height of 20μm, and a width of 50μm at the root of the mesa is formed near the center of a shadow mask 1 in the [011] and [01-1] directions. On the other hand, one each V-shaped groove which has an upper width of 55μm is formed on the surface of an n-type InP substrate 3 in the [011] and [01-1] directions after a silicon oxide film of 1μm in thickness is formed in the substrate 3. The position of the two grooves are decided correspondingly to those of the projecting sections 2. Then a shadow mask 1 is set on the InP substrate 3 so that the direction of the stripes of the mask 1 can become parallel to the [01-1] direction of the substrate 3.  When the shadow mask 1 is set on the substrate 3, the mask 1 is held by the substrate 3 by putting the projecting sections 2 in the recessed sections 4 of the substrate 3.

IPC: A61P43/00
Filed: 1993-12-24
Abstract: PURPOSE: To obtain a delayed and sustained release pharmaceutical preparation by including an ultrafine composite particle composed of a water-soluble core agent coated with a single hydratable diffusion barrier. CONSTITUTION: This pharmaceutical preparation can be produced by coating a water-soluble drug having a solubility of >=10 g per 1 liter of intestinal juice (e.g. propranolol hydrochloride) with a hydratable diffusion barrier having a thickness of >=20 μm. The barrier is produced by mixing a polymer capable of forming an insoluble film (e.g. acrylic resin) with an additive for controlling the hydration rate and permeability of the diffusion barrier and spray-coating the mixture to a core drug. The diffusion barrier delays the release of the drug for 2-10 hr after administration and then slowly releases the drug. The additive is selected from a completely esterified acrylic resin containing quaternary amine side chain, an anionic surfactant, a lubricant, a plasticizer, an inert water-soluble substance and their mixture.

After the dummy fuse has been blown, a blown trace is aligned. When the dummy fuse has not been blown correctly, a SCAN data (erroneous) is obtained. When it has not been blown correctly, a discrepancy is computed by means of the SCAN data and it is corrected by using the correction means 2. After it has been corrected, a genuine fuse is blown. Thereby, the alignment operation can be checked accurately and an accurate laser blowing operation can be always performed.

Title: Controller for helper roll speed
Inventor: UKATA HIDEO
IPC: C25D7/06
Filed: 1987-12-24
Abstract: PURPOSE:To prevent a band steel from being bruised by detecting the speed of a bridle roll for a speed master, converting the detected signal into a speed feedback signal of a helper roll to vector control a helper roll driving motor. CONSTITUTION:At the time of starting a bridle roll 4 for a speed master, a secondary magnetic flux operation circuit 25 of inverter devices 10-12 cannot accurately calculate the secondary magnetic flux from currents supplied to motors 7-9. Therefore, a speed control circuit 22 converts a speed reference of a generator 6 and a signal of a speed sensor 5 with a conversion circuit 27 and compares them with each other and outputs a q-axis current signal while a magnetic flux operation circuit 23 outputs a d-axis current signal corresponding to the magnetic flux. A vector control circuit 24, based on signals of both axis currents and of the speed conversion circuit 27, outputs current references for the motors 7-9, and controls the speeds of helper rolls 1-3 by way of a primary current control circuit 26 and an inverter 21. Then, when a controllable low speed range is reached, a uniform speed operation is performed with an output of the operation circuit 25. Thus, a band steel is prevented from being bruised.
