Title: Oscillation mixing circuit
Inventor: OHIRA TAKASHI
IPC: H03D7/12
Filed: 1988-11-08
Abstract: PURPOSE:To prevent leak of an oscillation frequency signal to an external circuit to stabilize the operation of an oscillating circuit by mixing the oscillation frequency signal obtained by an oscillating part and a high frequency signal led from the other end of a transmission line to obtain an intermediate frequency signal. CONSTITUTION:A field effect transistor(FET) 33 oscillates, and an oscillation(LO) signal is obtained by this oscillation frequency, and the reflection coefficient of a micro strip line 31 is '0' for the frequency of the high frequency(RF) signal, that is, almost all of this signal passes the micro strip line 31. Consequently, the RF signal inputted from an RF input terminal 47 through an RF matching circuit 49 passes the micro strip line 31 as it is and is applied to the gate of an FET 35. The RF signal and the LO signal are mixed by the nonlinearity of the FET 35, and the intermediate frequency(IF) signal having a difference frequency (¦fRF=fLO¦) is obtained on the drain side of the FET 35. Since this drain is provided with a low-pass circuit 39, only the IF signal out of three signals passes this circuit 39 and is outputted to an IF output terminal 55. Thus, the LO signal is prevented from leaking to an IF input terminal 47.

Title: Object image high speed processing method and modular system
Inventor: UEIN MOORISU DOORAN
IPC: G06T5/00
Filed: 1992-09-30
Abstract: PURPOSE: To provide a system and a method for processing image data obtained by the scanning of a document and generating compressed binary data of the image data to apply the data for communication and other purposes. CONSTITUTION: The scanning line of pixel image data generated by an imager 18 on a scanning line 14 is divided into plural channels #1 to #N, and after starting the scanning of a document 12, the parallel processing of image data are completed before the completion of scanning of the whole document. In each of plural channels #1 to #N, the threshold conversion and compression of pixel data are executed in parallel. Threshold conversion is executed by comparing a pixel concerned with its peripheral average gray scale by the use of an inspection window. Each channel has at least one superposed pixel area, which is used for evading an error between plural channels. Compression is executed in a direction vertical to the scanning direction by a method adaptive to standard compression algorithm such as a CCITT group 4.

Title: Chemical for treating semiconductor substrate and treatment method thereof
Inventor: HASE USHIO
IPC: H01L21/308
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the change of treatment performance with the lapse of time, by providing a chemical, which contains quaternary ammonium hydroxide and ozone and has an OH<-> concentration within a specific range, and setting the ozone concentration at a specific value of more. SOLUTION: A treatment chemical contains quaternary ammonium hydroxide and ozone, has an OH<-> concentration within a range of 10<-5> -10<-3> mol/l and an ozone concentration of 10<-5> mol/l or more. The concentration of quaternary ammonium hydroxide is preferably 10<-3> -1 mol/1. In the cleaning to remove particulates by using this treatment chemical, the loss during treatment due to the volatility and self decomposition of the chemical component is small and the life of the chemical is lengthened. Since the fluctuation of the composition is small, the chemical treatment performance is stabilized, thereby improving the yield and reliability of a semiconductor device. Further, the consumption of the chemical is remarkably reduced and chemical purchase cost and exhaust and waste solution treatment cost can be also greatly reduced.

Filed: 1985-12-16
Abstract: PURPOSE:To permit easy processing of the output signal of YMR head by providing another shielding yoke which is so constituted as to extend from a front upper yoke and to cover the upper yokes to said head. CONSTITUTION:The upper yokes 2, 3 are usually manufactured of a 'Permalloy(R)' film, etc. having about 0.5-1.0mum film thickness and act as the magnetic path to conduct the signal magnetic field generated in a magnetic recording medium 9 to an MR element 4.

Filed: 1994-10-25
Abstract: PURPOSE: To provide an electronic hole playing machine capable of effective inspection to check an unfair practice to suppress the winning occurrence excessively by outputting display corresponding to the number of games from generation of inner winning until generation of technically intervening winning. CONSTITUTION: When a medal is put into the slot of this electronic hole playing machine and a start button 6 is pressed down, whether an inner winning is hit or not is decided by drawing lots in a calculation control unit 1 as an inner winning generation means.

When the rotary reel images are stopped by pressing a stop button 7, a technically intervening winning is generated if the three rows of images are success patterns. In this kind of playing machine, if a technically intervening winning is generated, an inner winning corresponding to the technically intervening winning is referred for recognition and judgement and, if there are, the winning is determined. An unfair prize can be prevented by this way.

IPC: H02P6/06
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To reduce an angle error of a rotation position signal by a method wherein a differential voltage between the 1st neutral voltage of the stator windings of a synchronous motor and the 2nd neutral voltage of resistors, which are connected in parallel to the respective stator windings is integrated, and the zero-cross of a signal which is obtained by synchronously adding a periodical signal with an advance phase to the integrated signal with a position signal having a constant amplitude, is detected. SOLUTION: A 1st neutral voltage VN obtained from the connection point of stator windings 5a, 5b and 5c is applied to the non-reverse input terminal of an operation amplifier 1a, and a 2nd neutral voltage VM obtained from the connection point of resistors 6a-6c is connected to the reverse input terminal of the operation amplifier 1a for obtaining the integrated signal of a differential voltage VMN. A synchronous signal whose phase is ahead of the phase of the integrated signal is added to the integrated signal to compensate the shift of the integrated signal to a delay phase direction. Furthermore, the summation signal of the integrated signal and the advance phase synchronous signal is supplied to a zero-cross comparator 3 to obtain a rotation position signal with a reduced angle error.  With this constitution, a motor can be driven stably, even if a load fluctuates near the maximum efficiency point of the motor.

Filed: 1989-10-31
Abstract: PURPOSE:To realize the change of rotary directions and improve transmission efficiency, by changing the rotation number of a planetary friction plate by providing at an input shaft a motive power slide transmission portion and a movement friction plate, and meshing the 1st bevel gear fitted to the planetary friction plate with the 2nd bevel gear. CONSTITUTION:When a handle 42 is turned, an input shaft 19 is moved, and a movement friction plate 21 fitted to the input shaft 19 is moved as it is butting against a planetary friction plate 28. The 1st bevel gear 26 connected with an internal gear 25 meshes with the 2nd bevel gear 27, and the planetary friction plate 28 is fitted to its rotary shaft 27. In the case in which the movement plate 21 is positioned at the outer periphery portion of the planetary plate 28, the revolution cycle of the plate 28 is slower than the cycle of being reversely rotated by means of the 1st bevel gear 26, so an output shaft 30 is reversely rotated. As the plate 21 is being moved to the inside, the revolution speed of the plate 28 is gradually reduced, and positiveness and negativeness are balanced at a certain point, and as the movement is further advanced to the inside, the output shaft 30 rotates positively. Also, as the motive power friction plate is only one step, its motive power transmission efficiency is good.
