Title: Radar equipment
Inventor: ONOZAWA KAZUO
IPC: G01S7/42
Filed: 1982-10-20
Abstract: PURPOSE:To simplify a radar equipment and to avoid the interferential influence of a same polarized wave component, in the radar equipment for utilizing a circular polarization electric wave and a linear polarization electric wave, by transmitting only the circular polarization electric wave. CONSTITUTION:The transmission electric wave fabricated in a transmitter 1 is emitted from a circular polarization antenna 5 through a transmission and reception change-over circuit 3 as a circular polarization electric wave. The circular polarization component with a direction same to the direction at the time of emission among reflected waves from an object is received by a circular polarization antenna 5 and guided to a receiver 7 through the transmission and reception change-over circuit 3 to be outputted to a circular polarization receiving output terminal 9. The linear polarization component same to the polarization of a linear polarization antenna 6 among the reflected waves is received by the linear polarization antenna 6 and guided to a receiver 8 to be outputted to a linear polarization receiving output terminal 10. One transmission and reception change-over circuit and a distribution circuit are eliminated and, because an antenna for performing electron emission is one, the problem of electric wave interference is not generated.

Title: Picture reader
Inventor: HASHIMOTO YOSHIYUKI
IPC: H04N1/19
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent an AF(autofocus) driving motor from becoming a power swing condition even at a part in which a large driving force is needed in order to adjust the focus in a photographing optical system and the height change of an object is radical and also to minimize a vibration at the part in which a small driving force is sufficient and the height change of the object is slight. SOLUTION: The focus of a photographing system is adjusted based on height information of an object. At the that time, the driving force of an AF motor 20 is made large at the part in which the height change is radical and it is made small at the part in which the height change of the object is slight. Thus, the AF motor 20 can be made not to become the power swing condition at an operating time when the large driving force is needed and also the vibration can be minimized at the operating time when the small driving force is sufficient.

Abstract: PROBLEM TO BE SOLVED: To control delicate dose amount readily without complicating the manufacturing step, by performing heating treatment, and diffusing impurities into a region to become a channel from a thin film containing the impurities for imparting one-conductivity type. SOLUTION: After an active layer 103 is formed on a crystalline silicon film 102, a thin film 104 containing impurities for imparting one-conductivity type is formed on a region, which becomes the channel of the active layer 103. Then, heating treatment is performed, the impurities are diffused in a region becoming the channel from the thin film 104, and a diffused region 105 is formed. In this case, by the dopant which is doped into the channel, a region 100 is formed wherein the dopant required for forming a source/drain region is partially offset (the role is offset). The conducting type of the region 100 becomes the somewhat weak conducting type in a drain region 110. The region, whose conducting type becomes womewhat weak, functions as the high resistance region wherein the resistance becomes high in the region of 110.

Title: Multipurpose compass
Inventor: ODAWARA SUTEO
IPC: G01C17/04
Filed: 1992-06-17
Abstract: PURPOSE:To simply decide the pole position or the like of a steel tower without requiring a special knowledge or technique by a method wherein a compass is formed after an entire-circle protractor, an alidade and a square-arrangement recognition plate have been attached to a shaft in the central point. CONSTITUTION:By means of a stopper screw 10, the direction of an alidade 7 is set to a graduation O on an entire-circle protractor 3, and a pointer protrusion 4a on a square-arrangement recognition plate 5 is set to the graduation O on the protractor 3. The movement in the horizontal direction of an adjusting attachment is made free, and its horizontality is confirmed by a bubble level 11. By looking into a sighting hole in the alidade 7, its sighting is set to an already installed steel tower, the adjusting attachment is tightened and the protractor 3 is fixed. Then, by loosening a stopper screw 10 for the square- arrangement recognition plate 5, the sighting of the alidade 7 is set to a steel tower (or a mark on a place where a steel tower is to be constructed) at the rear. When the pointer protrusion 4a on the recognition plate 5 reads out an angle indicated on the protractor 3 and an angle is moved backwards by 1/2 of the angle, a square figure 6 indicated by the recognition plate 5 indicates the direction of the steel tower to be constructed.

Title: Controller of ultrasonic motor
Inventor: IZUNO YUJI
IPC: H02K11/00
Filed: 1990-07-11
Abstract: PURPOSE:To control the output frequency of a power supply means variably so as to minimize a speed deviation by a method wherein a plurality of fuzzy rules concerning an identical speed deviation and a switching means which switches the applicable fuzzy rules in accordance with a speed region are provided in a speed control means. CONSTITUTION:For instance in a high speed operation, when a speed deviation is +10rpm, i.e., the speed is too high, the compatibility of a fuzzy expression, 'a little faster (PS)', is '1' and a frequency deviation corresponding to the compatibility is +0.05kHz. Therefore, the output frequency of a power supply means 5 is increased from the present value by 0.05kHz. In a region where a plurality of membership functions overlap each other, a weighted average value is obtained in accordance with the rations of the compatibilities of the respective membership functions. That is to say, if the speed is higher than the target speed, the output frequency is increased to reduce the speed and, if the speed is lower than the target speed, the output frequency is reduced to increase the speed, so that the speed is always controlled to be the target speed. The rate of the variation of the output frequency is determined by a membership function produced in accordance with empirical values obtained by experiments.

Abstract: PURPOSE:To provide a modulator for antilock brake which permits the reduction of dimension of the modulator and provides the superior responsiveness in the initial variation of the brake hydraulic pressure in the switching from the normal brake application state to the antilcok brake control. CONSTITUTION:Since, in a modulator 30, a return spring 38 is arranged in inclination by a prescribed angle to the displacement direction of an expander piston 10, the max. necessary torque of a motor reduces, and the reduction of the dimension of the modulator 30 can be realized. Further, since a regulating means for deflecting the upper limit position of the expander piston 10 by a prescribed quantity toward the bottom dead center direction from a top dead center in the turning direction is provided, the displacement quantity of the expander piston 10 increases in the selection of the control state, and the initial variation quantity of the brake hydraulic pressure increases, and the responsiveness can be improved.
