Abstract: PURPOSE:To reduce the flaw of a track or the generation of chipping when the groove of the track is worked by forming a notched groove on the pole height side of a U-bar and forming a central part groove in a specified shape in the central part of the U-bar. CONSTITUTION:A notched groove 25 of a prescribed dimension is formed in a pole height side end part 24 of a U-bar 23, which is composed of an oxide ferromagnetic material, and a central part groove 26 of a prescribed dimension, for which width is made narrow in the direction of depth, is formed in the central part. Next, a non-magnetic thin film 29 formed in an I-bar 27, which is samely composed of the oxide ferromagnetic material, is faced to the above mentioned grooves 25 and 26, welded, and fixed by glass sticks 32 and 32. Afterwards, the non-magnetic thin film 29 fixed to the grooves 25 and 26 by the glass sticks 32 and 32 is ground to a degree that glass in the groove 25 of an obtained GB bar is slightly remained. After lapping is executed to the GB bar and a track groove 34 is worked so that the bottom part of the track groove 34 can be extended over the pole height side end part. Then, a track 38 is formed.

IPC: H04N5/265
Filed: 1989-03-28
Abstract: PURPOSE:To obtain the taking-out timing signal of a slave picture signal, which is converted at double speed with small circuit scale, without using a 1H line memory by using the output of a horizontal address counter as latch information and as comparison information according to bit selection. CONSTITUTION:A horizontal address counter 21 counts a clock from a preset value and obtains the count output of 10 bits for example. Out of the 10 bits, 9 bits (H1-H9) are supplied to an input part in one of first and second latch circuits 22(1) and 22(2). The outputs of the latch circuits 22(1) and 22(2) are respectively supplied to one of the comparators 25(1) and 25(2). The data cycle of the H0-H8 is double to the data cycle of the outputs H1-H9 and a coincident output EQS to be obtained from the comparator 25(1) is supplied to the set terminal of a flip-flop 26. Then, a coincident output EQR to be obtained from the comparator 25(2) is supplied through an OR circuit 30 to a reset terminal. Thus, the slave picture signal, which is converted at the double speed, can be obtained in an output terminal 28.

Filed: 1989-03-28
Abstract: PURPOSE:To obtain an image which is not black as a whole and has excellent gradation by providing converting means for converting multilevel pixel data into multilevel pixel data having low density value, and energizing means for energizing the converting means at each predetermined pixel period. CONSTITUTION:Since a digital image signal 116 has 4 bits, input data become a value of O-FH (H is hexadecimal number). The larger the value is, the nearer the data becomes white. A negative edge trigger flip-flop 123 outputs a video clock 111 divided by two as a VIDEO mask signal 124. The signal 116 is logically added with the signal 124 by OR gates 119-122, and input to a latch circuit 101 as a signal 117. Accordingly, the signal 117 becomes 'FH (white)' at its value at every other one.

IPC: B05D1/40
Filed: 1990-03-22
Abstract: PURPOSE:To equalize the film thickness by a method wherein a substrate is spinned in a vacuum vessel so as to dry up and solidify the coating solution. CONSTITUTION:An upper cup 14 is opened to mount a glass substrate 11 on a specimen base 13; liquid resist is dripped on the central part of the substrate 11 and then the cup 14 is closed; the substrate 11 is spinned at 300rpm for 5 minutes by a motor 12 to spread the resist over the whole surface; next the pump 12 is accelerated at 1000rpm; and after 10sec. exhaust step is started by a pump 24 to attain to the vacuum degree of 50Hg after 20sec. While preserving the vacuum degree using a pressure regulating valve 23, the spinning step is continued for 30sec. to be further prebaked at 90 deg. for 30 minutes in an oven. Through these procedures, coating solution in fluid state can be dried up and solidified in a vacuum vessel so that the phenomena of friction between air and the surface of coating solution as well as the sweeping wind may be eased thereby enabling the even distribution of film thickness to be realized while the drying and solidifying time are cut down.

Abstract: PROBLEM TO BE SOLVED: To effectively detect a failure without any additional complicated and expensive circuit by outputting an output pattern indicating failure from a plurality of sensors as a failure signal. SOLUTION: A vane 40 which has light blocking parts 41a-42h and light transmission parts 44a-44h and which is positioned on the shaft of rotor to reflect the angular position of rotor. When the part 44a-44h comes in front of a sensor 46a-46c emitting light while being positioned on a stationary member, the sensor detects the transmission light to send out a signal of logical zero (0) (space range). When one of the parts 42a-42h comes in front of one of the sensors 46a-46c, the light therefrom is blocked, and a signal of logical one (1) is sent out (mark range). The angular distance of 15 degrees between the respective sensors is smaller than the angular span in the mark region and space region, and the angular distance of 30 degrees between both end sensors is larger than the same. According to the relation, a sensor output pattern at the time of proper operation is 101, 100 or the like and is not 111. Accordingly when the sensor output is 111 or 000, a failure signal is generated without fail and it is detected.
