Title: Movable body-loaded target tracking device
Inventor: ASARI YUKIOKI
IPC: H04B7/26
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To correct the influence of oscillation and improve the tracking precision by analyzing the oscillation waveform included in an input to grasp the oscillation content, and performing a control in conformation to the analyzed frequency. SOLUTION: The oscillation of a movable body is detected by an oscillation detecting gyro 4 and inputted to an oscillation frequency identifying part 5a, and the detected oscillation data is recorded in an oscillation waveform recording part 11. This data is converted into a frequency spectrum by a Fourier transform arithmetic part 12, and an oscillation frequency calculating part 13 determines the dominant frequency component from the frequency spectrum and outputs it as oscillation frequency. A loop gain regulating part 6 changes a parameter so as to increase the loop gain near the dominant oscillation frequency. Consequently, the disturbance suppressing characteristic in the oscillation frequency is improved to suppress the oscillation, and the tracking precision can be enhanced.  The dominant oscillation frequency can be suppressed by the above operation, and high tracking precision can be kept.

Filed: 1979-12-21
Abstract: PURPOSE:To obtain the constant input and output frequency of a phase difference detecting circuit without regard to the rpn of the motor in a motor control circuit with a fail block loop, by changing the frequency division ratio of the output of the generator which is directly coupled to the motor. CONSTITUTION:The frequency of the output of an oscillator 1 is divided by a frequency divider C10, and the result is supplied to the phase difference detecting circuit 4. The output of the phase difference detecting circuit 4 passes a charging pump 6, and drives the motor 8 via an integrator 7. The frequency generator 9 is directly coupled to the motor 8, and the output of frequency generator 9 becomes the input  to a waveform shaping circuit 5. The output of the waveform shaping circuit 5 becomes the inputs to a switch 12 and a frequency divider B3. The rpm of the motor  8 can be changed by the selection of the switch 12. In this case, since the frequency  of the input and output of the phase difference detecting circuit 4 does not change  and the integrating constant of the integrator is constant, the circuit is not required  to be changed.

Filed: 1979-12-22
Abstract: PURPOSE:To improve performance and the degree of integration by simultaneously forming a high pressure resisting element region with a thick collector layer and a thin low pressure resisting element region in the same substrate. CONSTITUTION:An n layer 16 is selectively formed on a p type Si substrate 11 and n<+> layers 20, 21 at the outside and the inside. SiO2 on a surface is removed, an n epitaxial layer 23 is stacked, openings are made up to an SiO2 film 24 and As is diffused 27, 28. As is further diffused, n<+> layers 29, 30 are built up, B is diffused and p<+> layers 31 are formed, and the n epitaxial layer 23 is separated. A base 32, an emitter 33 and a collector extracting layer 34 of a high pressure resisting transistor and a base 35, an emitter 36 and a collector extracting layer 37 of a low pressure resisting transistor are built up. According to this constitution, the collectors of the high pressure resisting and low pressure resisting transistors are simultaneously formed thickly and thinly respectively, collector series resistance can be lowered  without increasing an area of the low pressure resisting transistor, and saturation  characteristics are improved. Since these elements can be made up for a short time  because of a shallow separating layer, a decrease of the specific resistance of the n  epitaxial layer can be prevented, and the pressure resisting of the transistors does  not lower.

IPC: G11B17/32
Filed: 1982-09-27
Abstract: PURPOSE:To stabilize the output of a magnetic head and prevent the abnormal wear of the magnetic head, by providing a regulating mechanism, which varies the press-contacting force of the magnetic head to a magnetic medium, in a carrier to which the magnetic head is attached while holding the magnetic head by a gimbals spring. CONSTITUTION:A magnetic medium 1 is held between magnetic heads 9 and 10, and a regulating screw 17 is loosened when the press-contacting force of them to the magnetic medium is too strong, and the regulating screw 17 is fastened to thrust up the magnetic head 9 when the press-contacting force is weak. Though this press-contacting force acts by the upper magnetic head 10, the magnetic head 10 is supported by a gimbals spring 12, and a strong force is supported by a supporting piece 13. Consequently, there is not a difference between outputs of magnetic heads 9 and 10, and they are stabilized. Further, the abnormal wear of magnetic heads 9 and 10 is prevented. When the bottom area of the magnetic head 9 is made slightly wider and the bottom is supported with three regulating screws 17 at least, the horizontality of the magnetic head 9 is determined more accurately.

Title: Method and device for lasing in gas laser using autogenous revolving gas flow
Inventor: MARUI TOMOTAKA
IPC: H01S3/03
Filed: 1990-06-28
Abstract: PURPOSE:To enable gas flow rate distribution within a discharge pipe in gas laser which oscillates due to excitation caused by discharge to be uniform by forming a high-speed turbulence restricting gas flow accompanied by autogenous revolving gas flow within the discharge pipe and by applying a high-frequency voltage to its outer periphery. CONSTITUTION:A pair of electrodes 2 are placed at an outer periphery of a discharge pipe 1 and a reducer 3 is connected to one edge part of the discharge pipe 1. A small-diameter edge of the reducer 3 is connected to the discharge pipe 1 and a large-diameter edge is connected to a semi-spherical shell body 5 through a direct pipe 4. When gas is flown from a gas introduction port 6, the flown gas flows along an inner surface of the semi-spherical shell body 5, thus forming a flow of spindle flow rate distribution with an annular minimum point within the reducer 3 or a taper pipe (a discharge pipe 1a) and resulting in autogenous revolving flow. Thus, gas flow within the discharge pipe 1 or 1a does not produce a turbulent flow even in a region with a large Reynolds number, thus resulting in a laminar flow accompanied by a revolving flow.

Title: Roman character/kanji converting system
Inventor: SHIYUDO TOMOKI
IPC: G06F17/22
Filed: 1985-07-30
Abstract: PURPOSE:To omit redundant procedures and mistakes and to ensure the highly efficient input of Japanese sentences by securing such a constitution where a Japanese sentence can be supplied according to its indicated reading. CONSTITUTION:An input Roman character string 'KINYUU' is compared with the header of a Roman character string of a forcible converting information storage means 5. Thus the coincident Roman character header is detected. In this case, the coincidence is secured with the Roman character header 'KINYUU'. Then the input Roman character string 'KINYUU' is replaced with the first one of plural corresponding KANA (Japanese syllabary) character strings, i.e., 'KINYU' of the first place. The result of this replacement is displayed on a display means 2. If no desired KANA character string is obtained, another applicable KANA character string is selected out of the means 5 by a next candidate selecting means 6. Thus the input Roman character string is converted into the second KANA character string 'KINYUU'. Thus a desired KANA character string 'KINYUU' is obtained to the input Roman character string 'KINYUU'.

Title: Speed change control method of vehicular automatic transmission
Inventor: YASUE HIDEKI
IPC: F16H61/08
Filed: 1984-08-10
Abstract: PURPOSE:To improve various characteristics such for example as specific fuel consumption, power performance, and shock produced in speed change, and thereby elimate uncomfortableness of a driver by achieving increased speed change stages in higher engine load while reduced speed change stage in lower engine load. CONSTITUTION:With higher engine load, many seed change stages are achieved, while with lower engine load, reduced speed changes achieved. Hereby, an engine can smoothly be changed in its speed without subjecting overload thereto, so that durability of a frictional member can be improved together with the improvement of specific fuel consumption, power performance, and speed change shock, etc. In addition, since the number of times of speed changes is reduced, uncomfortableness of a driver can be eliminated.
