Patent JP-S58151025-A (JP)
Title: Exposing method of photosensitive film of semiconductor wafer
Inventor: SAITOU KAZUYUKI
IPC: G03F7/20
Filed: 1982-03-04
Abstract: PURPOSE:To obtain accurate patterns, by a method wherein when a photosensitive film formed on the surface of a semiconductor wafer is adhered to a mask by vacuum extraction and exposed to light for performing photoetching, the sensitized surface is disposed to face the mask with interval determined based upon resolution, image quality and pitch error, and then they are adhered with each other by vacuum extraction. CONSTITUTION:Most defective adhesion between a photosensitive film formed on a semiconductor wafer and a mask concentrates upon the central part of the mask. This is because the adhesion can not be performed in the ideal manner as that begins at the center then spreads out to the periphery. Accordingly, when the mask is adhered to the photosensitive film by vacuum extraction, the surface and mask are disposed facing with each other with interval determined based upon resolution, image quality and pitch error, then the mask is shaped out to the convex form by vacuum extraction so that the surface and mask are first adhered at the central part then spreadingly adhered to the peripheral part. When the diameter of the wafer is 4 inches, the interval should be 30  10mum.

Abstract: PURPOSE:A copolymer of ethylene and an alpha-olefin is chlorinated through a three- staged process in which the temperatures are different from one another in individual steps to produce a chlorinated polyethylene with good processability, because of its low Mooney viscosity, high mechanical strength and good flowability. CONSTITUTION:At the first stage, the ethylene-alpha-olefin copolymer is chlorinated at a temperature more than 10 deg.C lower than the melting point of the copolymer to a level of 20-60% to the whole chlorination and at the second stage, the chlorination is effected at a temperature 5 deg.C higher than the above temperature and 5-15 deg.C lower than the melting point. At the third state, more than 10% of the total chlorination is effected at a temperature by 5-15 deg.C lower than the above reaction temperature. The resultant product has a density of 0.905- 0.940g/cm<3>, a melting point of 106-130 deg.C, a melt index of 0.01-100g/10min, a chlorine content of 20-55wt% in an ethylene-alpha-olefin copolymer with the number of side-chain alkyl groups of 3-35 per 1,000 of carbon atoms in the main chain, a Mooney viscosity of 10-60p at 100 deg.C and a peak caused by the amorphous portion between 8 and 15 deg. in the Black's angle theta of X-ray wide angle diffractiometry.

Title: Incoming call transfer control method for mobile terminal equipment
Inventor: INAGUMA TAKAO
IPC: H04W8/04
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To simplify the operation by adopting the configuration such that an exchange automatically discriminates whether or not incoming call transfer is to be conducted after the incoming call transfer is once registered and makes required connection so as to eliminate the need for registration/release of the incoming call transfer for every incoming call transfer. SOLUTION: When a mobile terminal equipment A is resident in a radio area Z1 at which th terminal equipment A desires incoming call transfer, the terminal equipment A dials a special number X and a telephone number B of a stationary terminal equipment B being a transfer destination sequentially to register the incoming call transfer. A mobile exchange 11 stores incoming call transfer information C obtained through combination of current position information of the terminal equipment A read from a mobile subscriber file 12 and to be registered automatically and the telephone number B to the file 12. When a connection request comes to the terminal equipment A, the exchange 11 reads the information C of the file 12 and connects the connection request call to the terminal equipment B or B depending whether the terminal equipment is resident in the area Z1 or Z2 .  Thus, the propriety of execution or release of the incoming call transfer is automatically discriminated and processed depending on the position of the terminal equipment A and then the operation for the incoming call transfer is simplified.
