Title: Method for removing foreign matter from surface of glass substrate
Inventor: MATSUMOTO KIYOSHI
IPC: B24B9/08
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To remove foreign matters such as top speck from the surface of a glass substrate produced by float-glass process by immersing the substrate in an aqueous solution of an inorganic acid containing bivalent chromium ion. SOLUTION: A float glass substrate is produced by continuously casting a molten glass on the surface of a molten metal bath and forwarding the formed glass ribbon along the surface of the molten metal bath. The glass substrate is immersed in an aqueous solution of an inorganic acid containing bivalent chromium ion to dissolve and remove small foreign matters existing on the surface of the glass substrate. The aqueous solution of the inorganic acid is e.g. a solution containing at least one kind of acid selected from hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid and hydrofluoric acid. Preferably, an organic acid such as citric acid is added to the inorganic acid solution to lower the deactivation rate of bivalent chromium ion to trivalent chromium ion caused by the oxidation with air.

Title: Radio receiver
Inventor: KOBAYASHI KEIJI
IPC: H04B1/06
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To reduce a time of AF search (a function that other broadcast station broadcasting a same program is searched when the electric field strength of a broadcast station listened to by the user at present is deteriorated and the searched broadcast station is automatically selected when the broadcast station has a prescribed electric field strength or over) in the case of receiving a radio data system(RDS) broadcast and to prevent a sense of incongruity in a listening sense by the AF search. SOLUTION: In the case of detecting a station during AF search, an electric field strength detection circuit 6 detects the reception electric field strength depending on an output signal from an IF amplifier circuit 4. When the reception electric field strength is higher than a reference level, a comparator circuit 8 provides an output signal of an 'H' level. Furthermore, when an output signal from an FM detection circuit 5 is within a range between reference values A and B of a window comparator 12, the window comparator 12b generates an output signal of an 'H' level. Thus, a 1st station detection signal is generated from a 1st station detection signal generating circuit 13 and fed to a control circuit 1 via a selection circuit 14 to detect a station for the AF search.  Since the station detection time of AF search is reduced because there is no delay element having a large delay time in a signal line.

Title: Production equipment for semiconductor element
Inventor: NISHIGUCHI KATSUNORI
IPC: B26F3/00
Filed: 1987-05-01
Abstract: PURPOSE:To prevent damage from developing in chips by a method wherein a tape, onto which a wafer is seated, is mounted under tension just under a flexible mat, which is supported peripherally, so as to press an upward projected spherical surface part against the rear surface of the wafer by pressing the mat, the tape and a pressing means against one another in order to separate chips from one another. CONSTITUTION:A wafer 3 is seated on a tape 8 under the state that the surface, onto which chips are formed, faces to a mat 2. Next, the mat 2 and the tape 8, which is located just under the mat 2, are moved downwards by a driving means in order to press them against a projected spherical surface part 7. Since the projected spherical surface part 7 is heated in advance up to a predetermined temperature, the ductility of the tape is enhanced. The wafer 3, which is pressed by the projected spherical surface part 7, deforms spherically and projects upward in the state where the wafer 3 is in contact with the rubber mat 2. As a result, the wafer starts to break at its central part and break spreads to its peripheral part. At that time, pressures having same intensities are applied on respective chips formed on the wafer 3, resulting in developing no damage in the chips and allowing to precisely separate the chips.

Examples of the functionalizing agent are water repellents (e.g. a silicone compound having both molecular ends aminated) and hydrophilic agents (e.g. polyethylene glycol having both molecular ends hydrolxylated). Ethylenediamine, diethylenetriamine and p-phenylenediamine are examples of the water-soluble diamine.

Abstract: PURPOSE:To stabilize the quality of the optical information recording and reproducing device by increasing the plate thickness of an outer periphery part around slits of an optical scale and promoting consequently its flexible rigidity. CONSTITUTION:A linear encoder plate 20 is fixed to pillars 21a and 21b via a screw 23 and a long hole 20a with a stepped screw 24. The slits 20b are provided at equal intervals with their lengths in the direction of B-B' on the plate 20, where the flexible rigidity is maintained by an extremely thin slit part 20c and a thick outer periphery part 20d. The encoder plate 20 is provided in a gap between a linear sensor light emitting part 33a and a light receiving part 33b. When an optical head 30 is moved in the direction of A-A', since the slit part 20c is thin with narrow slits 20b, excellent optical characteristics are obtained, while since the outer periphery part 20d has enough rigidity, neither flexure nor dislocation take place in the direction of B-B', thus obtaining the optical information recording and reproducing device having the optical scale and a detecting means for accurately counting the number of slits.
