Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To provide the synchronization detector in which a horizontal synchronizing signal is not deviated in the unit of sampling time even when noise is included in an input video signal or a DC component is fluctuated. SOLUTION: The detector is provided with a comparator 8 extracting a horizontal synchronizing signal included in a digitized video signal, a variable phase oscillator 23 operated to match a phase with that of a comparator output by using a PLL circuit, and a control circuit controlling a phase of an output of a character synchronization generating circuit 25 with an output phase of the variable phase oscillator 23 when a phase difference between an output of the variable phase oscillator 23 and an output of the character synchronization generating circuit 25 exceeds a prescribed value.  A deviation in the unit of high frequency signal is eliminated by a PLL with respect to a deviation in an output of the comparator 8 in the unit of clock signals and when a phase difference between the output of the variable phase oscillator 23 and the output of the character synchronization generating circuit 25 does not exceed a prescribed value, since the output phase of the character synchronization generating circuit 25 is unchanged, deviation in the output phase of the character synchronization generating circuit 25 with respect to the synchronizing signal of the input video signal is not caused.

IPC: H01L21/027
Filed: 1984-07-03
Abstract: PURPOSE:To provide the superposition of semiconductor device with high precision while making resist coating shapes at both sides of a basic pattern symmetrical by a method wherein once coated resist is forced to resume flowing. CONSTITUTION:Phenol novolak base positive type photo resist 4 is dripped on a wafer 1 to be turned at around 5,000rpm for 3sec for coating the wafer 1. After a spinner stops turning, the resist 4 resumes flowing to be formed into symmetrical shapes at both sides of pattern. In such a status, the resist 4 is continuously prebaked to thoroughly remove any residual solvent. The interval between the coating and prebaking processes may be within 20sec. Through these procedures, the resist film thickness at both sides of basic alignment pattern 2 may be equalized to make the actual mark center C0 and the apparent pattern center C' correspond with each other providing superposition of semiconductors with high precision. The coating time may be recommended for 2-5sec. Besides, any resist film exceeding 2mum thick will not be practical in terms of the signal intensity level of chip alignment.

IPC: H03G3/20
Filed: 1980-10-03
Abstract: PURPOSE:To set an output level in a range sufficiently wider than the operation level range of a detector and to make a detector input level constant to reduce the temperature fluctuation, by providing a variable attenuator between a coupling circuit and the detector to change the attenuation quantity in accordance with the  output set level. CONSTITUTION:A part of the output of an amplifier 3 is taken out by a coupling circuit 5 and is inputted to a detector 6 through a variable attenuator 11. The output of the detector is compared with a reference voltage and is amplified in 7 and is applied to a variable attenuator 2. By this constitution, since the input level of the detector 6 is held in a narrow range when the attenuation quantity of the variable attenuator 11 is changed in accordance with the output set level of a  terminal 9, the output level is set in a range wider than operation level range of the  detector 6. By making the detector input level constant, temperature fluctuation is  made slight.

IPC: G10F1/02
Filed: 1991-06-11
Abstract: PURPOSE:To make a thrust constant irrelevantly to a stroke and to prevent an initial thrust from decreasing by providing a resistance correction part which is so formed that magnetic reluctance generated between a fixed yoke and a movable part is varied according to the movement of a movable part. CONSTITUTION:An armature 10 is joined with the front-side reverse surface of a key. A movable yoke 25 which has a tapered part 25a at the upper part is provided instead of a movable yoke whose upper part diameter is constant and the tapered part 25a is decreased in diameter gradually toward the top. Therefore, when a solenoid coil 5 is excited by an electronic controller, the movable yoke 25 is attracted toward the fixed yoke 1. Consequently, the interval to the fixed yoke 1 is varied with the stroke of the movable part, so the magnetic reluctance between them is varied. The magnetic reluctance between the movable part and the other end side of the fixed yoke is also varied with the stroke. The magnetic reluctance of the whole system is the sum of those magnetic reluctances, so the total magnetic reluctance is affected by the variation of both the magnetic reluctances of the respective parts.

Title: Oil pressure controller for automatic transmission
Inventor: SAKAGUCHI SHINYA
IPC: F16H61/06
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To control clutch pressure with high precision and no increase in the number of component parts employed. SOLUTION: When a manual bulb 80 is shifted to the reverse range, line pressure PL is led into a pressure passage A to bring R/C under high pressure. Between the R/C and the manual bulb 80 an accumulator 8 is disposed of which back pressure is controlled by the pressure in a pressure passage 31. The pressure passage 31 communicates with a pressure passage 122, or the output passage of a lockup control solenoid valve 110. The pressure control by the lockup control solenoid valve 110 thus includes the back pressure control of the accumulator 8 to thereby control clutch pressure with high precision and no increase in the number of component parts employed. The accumulator 8 is utilized also as the pressure relieving means for the reverse clutch to save the costs therefor.
