Title: Optical mask and mask blank and their production
Inventor: FUKUSHIMA YUICHI
IPC: G03F1/30
Filed: 1993-09-28
Abstract: PURPOSE:To obtain a high resolution in the transferred patterns obtd. by an optical mask by setting the wavelength of exposing light at the time of using the optical mask in such a manner as to make the transmittance which light transmits light transmission parts higher than the transmittance at which the light transmits phase shift parts. CONSTITUTION:A first transparent layer 2 is formed on a transparent substrate 1 and phase shift patterns are formed by a second transparent layer 3 thereon. Further, light shielding patterns are formed by a light shielding layer 4. There is a relation between the film thickness (d1) of the first transparent layer 2 and the film thickness (d2) of the second transparent layer 3. The difference in the transmittance (i.e., DELTA[TP1, TP2] between the transmitted light P1 (transmittance TP1) of the light transparent parts and the transmitted light P2 (transmittance TP2) of the phase shift parts is so set as to attain a positive value of >=1%. Consequently, the optimum phase shift effect is effectively obtd. and the variation in the size of the transferred resist patterns is prevented as well.

IPC: H03M1/36
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide an A/D converter that can reduce an offset of a comparator without increasing the power consumption and the circuit scale. SOLUTION: The A/D converter of this invention is provided with a plurality of comparators 1 each comparing an analog input voltage Vin with a reference voltage and a digital decoder 2 that generates a digital signal in response to the analog input voltage Vin based on an output of each comparator 1. Each comparator 1 has a preamplifier 3 and a multi-input differential amplifier section 4a connected to the post-stage of the preamplifier 3. The multi-input differential amplifier section 4a averages differential signals outputted from three adjacent preamplifiers 3 respectively to output a final differential signal. Thus, offsets by the preamplifiers 3 can be cancelled to attain highly accurate A/D conversion. Furthermore, since no resistor is employed for the averaging processing, the cost can be reduced and the power consumption can also be decreased.

IPC: G11B5/23
Filed: 1994-09-09
Abstract: PURPOSE: To obtain a process for producing a magnetic head capable of measuring the gap depth in the direction from the sliding surface of the magnetic head. CONSTITUTION: The opposite surface of one base material 1' of a pair of base materials 1', 2' constituting magnetic core half bodies is previously provided with a marking groove 7 of a prescribed size. For example, magnetic metallic films are formed on the opposite surfaces of these base materials and the gap is provided with a gap material. The base materials are welded to each other with glass and thereafter, the head sliding surface is lapped.

The management of the gap depth of even the heads having any shapes is, therefore, facilitated.  This method is also applicable to the magnetic heads of types not coated with the magnetic metallic films.
