Title: Manufacture of semiconductor device
Inventor: TOKUHARA SHINOBU
IPC: H01L21/66
Filed: 1987-10-19
Abstract: PURPOSE:To improve a yield in a heat treatment process by forming a target pattern of a constant emissivity in a part of the surface of a semiconductor wafer, and by detecting electromagnetic waves from the pattern surface with a pyrometer and making an accurate temperature detection. CONSTITUTION:A semiconductor wafer 1, housed in a heat treatment device equipped with a temperature detection means composed of a pyrometer 13, is heat treated as specified by heating it with a lamp. On that occasion a target pattern 2 for detecting temperatures of constant emissivity is formed on a part of the surface of the wafer 1. Detection of electromagnetic waves emitted from the pattern 2 of constant emissivity makes it possible to make an accurate temperature measurement not affected by patterns of a circuit formed region or the quality of materials. This enables the yield in a heat treatment process to be improved.

Title: Depletion control type separation stage
Inventor: ROBAATO RAUNTORII
IPC: H01L27/02
Filed: 1992-09-30
Abstract: PURPOSE: To enhance the overvoltage protective function, by a method wherein a depletion controlled isolation resistor is formed in adjacent N<+> diffused regions so that one of the N<+> diffused region may be connected to an input bonding pad and the first protective element, while the other one may be connected to the second protective element and the protected inner circuit. CONSTITUTION: A high concentration doping N<+> regions 16, 18 are formed in an N well 14 while the region 16 is connected to an input bonding pad 20. The region 18 is connected to a protected circuit body structure 21. Besides, when the high concentration doping region 16 is biased by 5 V, a depletion end 22 of the N well 14 is formed in the N well 14 further forming a P well depletion end 30 in a substrate 12. In such a constitution, an N well isolation resistor 10 forms a linear relationship with respect to the voltage versus current curve within the range of 0-10 V but within the range of 15-20 V, the trend starts to form a curried line at a specific constant current value according to the increase in the voltage. Furthermore, the resistance value of the isolation resistor 19 is increased corresponding to the increase in the voltage as well as the N well depletion region recedes in the direction of the high concentration doping region 16, thereby enabling the current value to remain at a specific value.

Title: Vibro-isolating device of rotary compressor
Inventor: IWAMI KENICHI
IPC: F04C23/00
Filed: 1984-12-11
Abstract: PURPOSE:To suppress a vibration and promote the easiness of equipment design and the improvement of reliability, by constituting a device having a spring, connected and fixed from one end of a fixing metal fixture wound on the external shell of a compressor, and an absorptive weight connected to be fixed to the spring and absorbing the vibration. CONSTITUTION:A compressor, when it is operated, generates a large vibration in a peripheral direction as shown by an arrow head A in the drawing, and this vibration is propagated to a leaf spring 27 from a fixing metal fixture 25 wound on the external shell of the compressor 15, vibrating an absorptive weight 29 fixedly connected with the spring 27. Here resilience of the leaf spring 27 causes the absorptive weight 29 to vibrate generating a delay for the peripheral directional vibration (arrow head A) of the compressor 15. And the absorptive weight 29, reversely by its vibration giving reaction suppressing the vibration of the compressor 15 through the leaf spring 27, remarkably reduces the vibration. While a vibration in the vertical direction as shown by an arrow head B in the drawing is absorbed by vibro-isolating rubbers 16 supporting a plurality of legs 17 in the periphery of the compressor 15. By the above constitution, the compressor 15 suppresses the vibration further enables the equipment design to be facilitated while the reliability to be improved.

Abstract: PURPOSE:Specific amounts of an alkali hydroxide and a silicate salt are added to an aqueous metal salt solution containing specific amounts of Ba and Pe, the mixture is subjected to hydrothermic treatment, NaCl is added, then, roasting is effected at a specific temperature and the product is rinsed to give a barium ferrite powder of high dispersibility and high smoothness. CONSTITUTION:An aqueous metal salt solution containing Ba and Fe at an gram-atom ratio of 1/(5-11) is heated up to about 50-130 deg.C and an alkali hydroxide such as sodium or potassium hydroxide is added in such an amount as it exceeds the neutralization equivalent so that the concentration of the alkali becomes more than 3mol/l. Further, a silicate salt is added to the aqueous solution so that Si becomes 0.01-5atom% based on the Fe in the solution. The resultant slurry is subjected to hydrothermic treatment by keeping it at 130-270 deg.C to form fine crystals of barium ferrite and allow them to precipitate. The precipitate is separated, rinsed with water, combined with 10-80wt% of NaCl and/or BaCl and roasted at 650-950 deg.C, washed and dried. Thus, a magnetoplumbite type of hexagonal barium ferrite powder is obtained.
