Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items of an information detector moving mechanism and to improve the positioning accuracy by moving an information detector along a guide groove formed in a chassis substrate interlocking with a reel base moving mechanism and positioning it. SOLUTION: An information detecting member 50 as an information detector is moved a long a linear guide groove 51 formed in a mechanical chassis 3 associatively with the operation of a reel base moving mechanism. When the information detecting member 50 is moved to a position corresponding to a small tape cassette 4A, its front end part is butted to the groove end part 51a of the guide groove 51, stopped and then positioned. When the information detecting member 50 is moved to a position corresponding to a large tape cassette, its rear end part butts to the stopper 48a of a rack supporting member 48, stopped and then positioned. Thus, the number of part items for the information detector moving mechanism is reduced, an operation is made simple and positioning accuracy is improved.

Title: Production of silicon dioxide film
Inventor: KOGURE NAOAKI
IPC: C01B33/12
Filed: 1993-12-13
Abstract: PURPOSE:To efficiently form a sound silicon dioxide film containing a small amount of sticking particles. CONSTITUTION:This method for producing a silicon dioxide film is to add aluminum to an aqueous solution containing silicon dioxide in a saturated state (a stock solution), produce an aqueous solution of hydrosilicofluoric acid (a treating liquid) in which silicon dioxide is converted into a supersaturated state, bring the resultant treating liquid into contact with a substrate and deposit the silicon dioxide film thereon. The amount of the added aluminum based on 1l stock solution is 0.05-0.4mol and the temperature obtained by subtracting the temperature for producing the treating liquid from the temperature of the treating liquid in producing the silicon dioxide film (a rise in temperature of the treating liquid) is 0-25 deg.C. The relationship between the amount of the added aluminum and the rise in temperature of the treating liquid is kept within a range so as to provide a prescribed value or above of the deposition rate of the silicon dioxide film and regulate the number of sticking particles of the silicon dioxide having >=0.2mum particle diameter to a prescribed value or below.

Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To perform simple and speedy tests for continuity in anti-dim heating wire sealed in the window glass of a vehicle, etc. SOLUTION: A first sensor 1a is brought close to an anti-dim heating wire of the window glass of a vehicle to detect both short-distance heating coil magnetism M1a at the time of the energization of the heating wire A and short-distance complex magnetism M3a formed of peripheral magnetism M2 formed of leakage magnetism which occurs from geomagnetism and peripheral equipment. Long-distance complex magnetism M3b including long-distance heating wire magnetism M1b and peripheral magnetism M2 formed of leakage magnetism which occurs from geomagnetism and spherical equipment is detected by a second sensor 1b at a distance from the heating wire. Then the value of the long-distance complex magnetism M3b is subtracted from the value of the short-distance complex magnetism M3a to obtain the computed value of heating wire magnetism M1.  On the basis that the computed value of the heating wire magnetism M1 is equal to a predetermined value or more, it is determined that continuity in the sealed heating wire A is non-defective.
