Title: Satellite navigation receiver
Inventor: KITAHATA ASAO
IPC: H03L7/02
Filed: 1991-03-06
Abstract: PURPOSE:To improve the stability of a reference oscillator in a satellite navigation receiver and to reduce the frequency error of a frequency signal to be given to a phase synchronizing circuit. CONSTITUTION:A reference oscillator 7 gives a reference frequency signal to a synthesizer 2 without special temperature correction. The synthesizer 2 gives the frequency signal, which is converted based on the frequency set value given from a control part 6, to a phase synchronizing circuit l. This circuit has the phase synchronized with the reception signal from a satellite. The control part 6 uses a temperature sensor 8 to measure the temperature of the reference oscillator 7 and corrects the frequency set value to be given to the synthesizer 2. This correction data is stored in a temperature correction data memory 5 as a table.

Abstract: PURPOSE:To enable the detecting of knocking accurately with a handy construction and enable checking of the soaring of cost. CONSTITUTION:A knocking sensor 1 is provided with a housing, a base, a terminal and the like and mounted securely on a cylinder block of an engine. A diaphragm 5 and a piezo-electric element 6 stuck on the diaphragm 5 are mounted at the tip part of the base held in the housing.

Moreover, the lengths of the axial lines of the vertical shaft and the horizontal shaft are subjected to a tuning beforehand so as to resonate with vertical vibration and horizontal vibration separately. When knocking is caused, the diaphragm 5 has two natural frequencies and a resonation is made as the vibration occurs at either of the frequencies. One diaphragm 5 only is used thereby achieving a simplification of the structure.

Abstract: PURPOSE:To recognize the cause of trouble with a high precision in a short time by online by comparing a transition actual result time and a transition standard time with each other to specify a faulty element device and estimating the cause of trouble by a cause estimate matrix. CONSTITUTION:Operation start and end signals of each element device are detected by a state detecting means 5a, and a time measuring means 5b measures the time from the operation start to the operation end of the element device itself or the transition actual result time required for the state transition between element devices by detected signals. A comparing means 5d compares the transition actual result time and the transition standard time with each other, and a judging means 5e judges transition in the normal sequence in the case of the transition actual result time shorter than the transition standard time but judges the existence of trouble in the pertinent element device itself or between element devices in the case of the transition actual result time longer than the transition standard time. The cause of trouble estimated by an estimating means 5g is displayed with a cause estimate matrix 5f. Thus, trouble of various manufacturing equipment in the manufacturing line is detected by online and its cause is quickly recognized.

Title: Film tension controller of article to be packaged at packaging machine
Inventor: TAKAMURA YOSHIYUKI
IPC: B65B25/04
Filed: 1990-02-20
Abstract: PURPOSE:To control the tension of a film corresponding to the ambient temperature for always maintaining a good package condition by a method wherein film hold release timing and film folding timing are relatively changed corresponding to the ambient temperature, and an article to be packaged is enveloped by a film with an optimum tension. CONSTITUTION:Driving timings of solenoids are stored in a program memory so that film hold release timing of a movable clamp member 18 becomes optimum corresponding to the set ambient temperature and the width and length of a tray 90. The film hold release timing of the movable clamp member 18 for a film 16a is changed according to the size of the tray 90 as well as the ambient temperature, so that film 16a is folded under the tray 90 with an optimum tension of the film 16a. As the film 16a expands well when the ambient temperature is high, the hold release of the film 16a is carried out in an earlier timing. As the film 16a does not expand well when the ambient temperature is low, the hold release is carried out in a delayed timing. Thus, the film 16a is hardly creased as film hold releasing timing is controlled.

Filed: 1988-02-25
Abstract: PURPOSE:To keep an adhesive property of a load feeding layer to a heat resistor good, by a method wherein a load feeding layer is composed of an adhesion layer and a gold conductive layer laminated thereon, and a line width of the adhesion layer is established as being wider than that of the gold conductive layer. CONSTITUTION:A load feeding layer 3 is composed of an adhesion layer 3a of NiCr or the like and a gold conductive layer 3b laminated this adhesion layer 3a, and a line width of the adhesion layer 3a is established as being about 5mum thicker each on one side than the line width of a gold conductive layer 3b. Consequently, since a photo resist pattern for patterning of the adhesion layer 3a is applied to a lower layer in a range of exceeding the line width of the gold conductive layer 3b in a manufacturing process of the load feeding layer 3, even through the lower layer positions corresponding to both side edge of the gold conductive layer 3b are over etched in an etching process, the line width of the adhesion layer 3a is never made narrower than the line width of the gold conductive layer 3b, and a practical adhesion area of the gold conductive layer 3b can be enough secured.

Title: Picture signal correcting device

IPC: H04N1/40
Filed: 1987-02-24
Abstract: PURPOSE:To surely eliminate an offset from a picture signal subjected to offset and level correction without losing the stability of an operation by providing a level conversion circuit, an A/D converter, a holding means, an arithmetic means and a gain control means. CONSTITUTION:In a picture signal correction, a level conversion circuit 5 converts the level of a black reference signal inputted from an image sensor 4 via an optical system 3, its output is digitized by the A/D converter 6 and stored in a storage means 7 as a black reference signal Ls. Then an arithmetic means 8 subtracts the signal Ls from a digitized picture signal Lo and gives the result as an output signal OUT externally and gives an output to the gain control means 9 for the level correction. The means 9 sets variably the conversion gain of the circuit 5 so that the maximum level of the input picture signal reaches a prescribed fixed level Lg to correct the offset Lo. Thus, both the offset and the level are corrected without losing the operation stability from the picture signal to attain the sure elimination of the offset.

Title: Liquid crystal driving device
Inventor: TOMITA HIDEO
IPC: G09G3/36
Filed: 1987-02-24
Abstract: PURPOSE:To prevent a friar on an image screen by a liquid crystal display element by detecting the second higher level among the levels of three primary colors signals and reducing the amplitude of a video signal when the detected peak value is large than a reference value. CONSTITUTION:The 2nd higher level among the levels of the three primary color signals R, G, B is detected by detecting means 4-7. The output of a max. value detecting circuit 7 is checked by a peak value detecting circuit 8 and the peak value thereof is detected. The detected peak value is compared with the reference value corresponding to the dynamic range of the liquid crystal display element by a comparator 11 and the amplitude of the video signal is reduced to the reference value or below when the peak value of this time is larger than the reference value. The generation of the friar on the image screen is thereby obviated even if the level of the video signal is large; in addition, the dynamic range of the liquid crystal display element is effectively utilized.
