Title: Level display device
Inventor: MEJIKA KENICHI
IPC: G11B27/36
Filed: 1994-10-31
Abstract: PURPOSE: To extend a level display range without increasing cost even when there is offset. CONSTITUTION: An input signal is supplied to a power amplifier 18 via a muting circuit 40, an output of the muting circuit 40 is made onto DC by a rectifying circuit 22, its rectified output is supplied to a system control circuit 24, the amount of offset included in the rectified output is detected, and the level display is performed based on the rectified output obtained based on the rectified output obtained by subtracting this offset amount. When the stop of a tape traveling system is controlled by the system control circuit 24, the offset amount is detected. By A/D-converting the offset based on the canceled rectified output, resolution of about 8 bits is achieved and a level display range of 30dB or more is achieved.

Abstract: PURPOSE:To simultaneously measure a time and a wavelength by a method wherein a sample irradiated with the beam of a laser apparatus is irradiated with probe beam and this probe beam is subjected to wavelength dispersion to be removed as an intensity change at every wavelength. CONSTITUTION:Laser beam is separated into a fundamental wave omega and secondary and tertiary high-frequency waves 2omega, 3omega by a prism 2 and the high-frequency wave 3omega is adjusted in time by a beam delay circuit 3 to irradiate a sample 11 as exciting beam 20 and the fundamental wave omega becomes white beam of a continuous spectrum by a cathode 10 and is adjusted in time to become probe beam 21 which in turn transmits through a spectroscope 13 to obtain a spectrum and a slit image is formed on a streak camera 14 and swept at high speed to be converted to a streak image. At this time, the high-frequency wave 2omega is converted to an electric signal by a PIN photodiode 6 and the electric signal is adjusted in time so as to synchronize with the exciting beam 20 and the probe mean by a delay circuit 12 to trigger the sweeping circuit of the camera 14. By this method, the spectrum data of beam to be measured and the data of the timewise change of the intensity of said beam are simultaneously obtained.

Title: Original picture reader
Inventor: MIURA TAKAHITO
IPC: H04N1/405
Filed: 1991-09-20
Abstract: PURPOSE:To prevent the deterioration of picture quality by performing the halftone reading processing of a multilevel picture signal of the output of an arithmetic means virtually increasing the number of bits of the multilevel picture signal of the aimed picture element based on the multilevel picture signal of the surrounding picture element having the maximum correlation relation with the aimed picture element by use of a non-linear threshold value. CONSTITUTION:When taking a picture element E in a chart (a) as an aimed picture element, surrounding picture elements B and D have the maximum correlation. When applying the coefficient of the digital filter in a chart (b), the level of the aimed picture element E becomes E'=2E+B+C. In this case, the number of bits of a multilevel picture signal of picture elements E, B, and D is 4 bits. As a result, the picture element E is virtually transformed into 6 bits in this calculation, and the gradient can be increased from 16 to 64. Then the 6-bit multilevel picture signal is subjected to halftone reading processing by applying the dither matrix in a chart (c) as the threshold value, thus obtaining a non-linear characteristic with the resolution of a part with low luminance level, that is, the one with high density level improved. Thus, the deterioration of the picture quality can be prevented.

Abstract: PROBLEM TO BE SOLVED: To effectively remove the trend component of a contour measuring instrument from a measurement data curve without increasing the load by dividing measurement data into an arbitrary number of segments and respectively assigning specific geometric shapes to the segments, and then, removing the components of the assigned geometric shapes. SOLUTION: A shape measuring machine 1 has a table 11 for placing a work 2. A column 12 is fixed to the table 11 and a slider 13 is attached to the column 12 in a vertically movable state.

The measuring machine 1 is actuated to sample measurement data and the data are divided into a plurality of segments at regular intervals H in the direction H. Then a straight line is assigned to each segment and the values of the straight lines are subtracted from the measurement data by executing trend correction. Consequently, trend components can be removed and data analysis, such as the spectrum analysis, correlation analysis, etc., can be performed.

Inventor: KAMIYA KAZUYUKI
IPC: B65D51/16
Filed: 1994-11-02
Abstract: PURPOSE: To prevent an aerosol container from bursting when it is exposed to a high temperature. CONSTITUTION: A through hole 22d is provided at the bottom of a mountain cap 22 which is fixed on a container body 21 of an aerosol container 1, a valve mechanism 3 being mounted to the cap 22, and the hole 22d is closed by a pin 4 made from shape memory alloy. The pin 4 is manufactured so that legs 4b, 4c thereof extend so as to be released from the hole 22d at a high temperature. When the container 1 is thrown into a fire or kept at a high temperature for a long period of time, the internal pressure of the container rises and there is a danger of bursting; however, the pin 4 is heated and deformed so that it can be released from the hole 22d, and hence the pressure can be relieved from the hole 22d and danger of bursting can be avoided.

IPC: H03K5/26
Filed: 1987-10-26
Abstract: PURPOSE:To save power consumption by providing a tri-state logic output circuit outputting a tri-state logic signal taking a 3rd logic level between 1st and 2nd logic levels in a path taking the logic level so as to make the size of the title circuit small. CONSTITUTION:When binary logic signal S3, S4 are both at the 2nd logic level, transistors(TRs) Q1, Q2 keep nonconductive state and then a constant current depending on a constant power supply line H1 flows through a resistor R2, a TR Q3 and a constant current source H1 from a power supply line E1 toward a power supply line E2. Moreover, when the binary logic signal S3 takes the 2nd logic level and a binary logic signal takes the 1st logic level, the TR Q3 keeps the conductive state and the TR Q2 keeps the conductive state, the TR Q1 keeps nonconductive state and the TR Q4 is nonconductive state. Thus, a tri-state logic signal is outputted as logic signals S1', S2' from output terminals T1', T2'.

Title: Optical assembly for observing panoramic scene
Inventor: JOHN E DAVIS
IPC: G03B37/00
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To generate the image of a panoramic scene on a flat focal plane by generating a small F-number by a visual field angle perpendicular to the output optical axis of an optical assembly. SOLUTION: Energy incoming from the panoramic scene involving the angle of elevation enters an aperture 110, and is reflected by a first element 102, and optical power forms an imaginative pupil 113. The energy is reflected downward by the element 102, and is reflected to the ternary surface of the subelement 42 of a third element by a concave mirror 78. The energy is moved between secondary and ternary surfaces 76 and 42, and passes a visual field diaphragm 112 and the imaginative pupil. A real pupil 146 is relayed to the second surface 148 of a filter and a cold diaphragm 48, and the visual field diaphragm 112 limits the visual field angle of the energy for a route descending from the element 42 to the element 44, and a baffle 74 normally limits incoming radiation deviated from a shaft abutting the surface of an optical element 44.  Thus, the small F-number is generated at the visual field angle nearly perpendicular to the output optical axis of the optical assembly on the panoramic scene.

Filed: 1989-10-16
Abstract: PURPOSE:To decide the center frequency with high accuracy by forming a throughhole and/or a non-throughhole to at least >=1 vibrator of plural vibrators including input and output side longitudinal vibration sound chips. CONSTITUTION:Throughhole groups 32a, 34a with a sufficiently smaller aperture than the longitudinal vibration resonance wavelength are formed to input and output side longitudinal vibration sound chips 32, 34. Thus, even when sufficient dimension accuracy is not obtained due to the etching processing when the said input and output side longitudinal vibration sound chips 32, 34 are manufactured as one element, the fluctuation of the center frequency of the composite longitudinal vibration mechanical filter, that is, the deterioration in the pass band characteristic is not caused by the effect of the throughhole groups 32a, 34a made by the etching processing or the like simultaneously.
