Title: Measurement value processor for engine control sensor
Inventor: AONO SHIGEO
IPC: F02P5/15
Filed: 1979-01-16
Abstract: PURPOSE: To secure the accuracy higher than the resolution of the A/D converter by amplifying the sensor output via two amplifiers featuring different amplification factors and then selecting one of the output of the two amplifiers according to the level of the sensor output for the A/D conversion.  
     CONSTITUTION: The output of air current volume sensor 102 is amplified 106 and then applied in parallel to 1st amplifier 108 of 1-fold amplification factor as well as to 2nd amplifier 107 4-fold amplification factor each. And the output of one side is applied to A/D converter 110 after the selective switching given at switching circuit 109. The switching of circuit 109 is done by switching the output of amplifier 108 to the input of the A/D converter via control circuit 111 when the A/D conversion value of the output of amplifier 107 has overflowed. In such way, the accuracy higher than the resolution of the converter can be obtained via the A/D converter featuring the limited bit number. Thus the execution time can be decreased for the A/D conversion, and the efficiency can be enhanced for the measurement process.

Abstract: PURPOSE: To simplify fixation by disposing a housing and a support for the purpose of fixing the support in the housing and reversibly fixing the support into the housing. CONSTITUTION: When the element of a form for slabs is placed in its position, first layer concrete 1a is placed to form the slab of the front step after the aperture of the housing is closed by a cap 12. Pressure is thereafter applied on the support in such a manner that the support is snapped into the housing, by which the assembly of the support is executed. The cap is removed from the bushing support upon ending of the concrete placement and the shaft of the bushing cut with external screw threads in correspondence to the support cut with internal screw threads in a position 15 is tuned to fix the bushing. As a result, the direct introduction of the bushing support into the housing is made possible without carrying out cleaning work.

Title: Manufacture of thin film transistor
Inventor: MATSUMOTO TOMOTAKA
IPC: G02F1/1368
Filed: 1987-01-07
Abstract: PURPOSE:To obtain preferable contact characteristic and reproducibility and to provide the manufacture of a thin film transistor in simple steps by irradiating a laser light from behind a light transmission insulating substrate to decompose reaction gas, and selectively removing an N<+> type Si layer covered on a conductive material layer by radical generated as above. CONSTITUTION:Since laser light 10 passes through an N<+> type Si layer, fluorine or chlorine reaction gas is decomposed in the opening 11 of an opaque conductive material layer 2 to generate fluorine radical or chlorine radical. The fluorine or chlorine radical reacts with the N<+> type Si layer 3 to proceed an etching. Here, reaction gas pressure is controlled to reduce the mean free stroke of the fluorine or chlorine radical, thereby locally limiting the etching only to the vicinity of the position where the radical is generated. Accordingly, the etching is not proceeded at a part covered on the layer 2, but only the layer 3 covered on the opening 11 for transmitting the light 10 is selectively removed.

Title: Deceleration device for small prime mover
Inventor: AOKI YASUHIRO
IPC: F16H7/12
Filed: 1989-01-09
Abstract: PURPOSE:To make it possible to drive with extremely low noise and low vibration by constructing a deceleration device out of only a toothed pulley and a toothed belt. CONSTITUTION:When a rotational shaft 5 of an electric motor starts to rotate, the rotation is transmitted to an input pulley 6 that is fixed on the shaft 5, and the pulley 6 is rotated at the same rotational speed with the shaft 5. The rotation of the pulley 6 is then transmitted to a first toothed pulley 11 through a first toothed belt 15, and a second toothed pulley 12 that is solidly provided with the pulley 11 is rotated at the same lowered rotational speed with the pulley 11. The rotation of the pulley 12 is further transmitted to an output pulley 16 through a second toothed belt 21, and an output shaft 17 to which the pulley 16 is fixed is rotated. As the rotation is transmitted only by the toothed pulley and the toothed belt, engagement of toothed gears does not occur at all, and driving with extremely low noise and low vibration can thus be achieved.

Title: Impulse response measuring apparatus
Inventor: IWATA KAZUYA
IPC: G01M99/00
Filed: 1992-01-10
Abstract: PURPOSE:To highly accurately measure the impulse response of an object to be measured. CONSTITUTION:A digital signal read from a digital source or the like is input from an input terminal 1. A response signal from an object to be measured to a signal wherein the digital signal has been converted into an analog signal is input from an input terminal 4. The analog signal input from the input terminal 4 is synchronized with the digital signal input from the input terminal 1 and converted into a digital signal by an A/D-converter 5. The time shift between the converted signal and the digital signal input from the input terminal 1 is corrected with the digital signal used as a reference, the ratio of the corrected signal to the digital signal is calculated in a frequency region by a calculator 11, and this is again converted into a time-base signal by a calculator 13 to be output. Since no impulse signal need not be used as a measuring signal, average power in a time-base direction of the signal is large, while use of a signal of a wide frequency range allows measurement of the output response at the rime of a large input of the object to be measured.

(Mw/Mn), both measured by high-temp. gel permeation chromatography, is 10 or lower. The film is heated ion the temp. range of the melting point of the polyethylene to [(melting point of the polypropylene)+10 deg.C]. Monoaxial stretching is then conducted at -20 to 60 deg.C to make the film porous, followed by further stretching in the temp. range of 60 deg.C to [melting point of the polyethylene)-5 deg.C], thereby giving the porous film. It is suited for use as a battery separator.

Title: Method and device for measuring cable twist
Inventor: TANOMI YASUHIRO
IPC: G01B5/25
Filed: 1983-01-13
Abstract: PURPOSE:To make the measurement accurate and quick, by supporting a cable by a rotary body that is supported by a casing to which weights are attached, and measuring the degree of the twisting of the cable with respect to the casing by a rotation gage which is connected to the rotary body. CONSTITUTION:When a cable 3 is suspended by steel towers 2 and 2, a twisting roller 17 is firmly fixed to a specified position of the cable 3. When the cable 3 is suspended and twisted around, rollers 10 which support the twisting roller 17 are rotated, since the rotation of a casing 4 is regulated by weights 7 and 7. Therefore, rotation gages 16 and 16, which are coupled with the rollers 10 and 10, measure the direction and number of rotation of the cable 3. The measured values are transmitted to a worker's receiver from an FM transmitter. The cable 3 is corrected to the adequate state based on the number and direction of twisting, and thereafter the cable is suspended between the steel towers 2 and 2. Thus the measurement can be performed accurately and quickly.

CONSTITUTION:When the operation program is to be written or rewritten, an instruction from an external device 8 is decoded in a CPU6, and when the decoded instruction is the one for the writing of an operating processor, an operation program writing control program 6a in the CPU6 is started and executed. On the other hand, when identification information is already written, the identification information is read from an identification information storing part 3, and the collation between the read identification information and input identification information is executed. Further, it is decided whether both the pieces of identification information coincide with each other or not, and the input new identification information or attribute information is accepted only when both the pieces of identification information coincide with each other. The CPU6 decides whether both the pieces of identification information coincide or not, stores either the identification information or the attribute information to a corresponding storing part in either an attribute information storing part 2 or the identification information storing part 3, and executes rewriting processing for both pieces of information.
