Title: Seal print collator
Inventor: SUZUKI YOSHIO
IPC: G06K9/00
Filed: 1984-03-12
Abstract: PURPOSE:To attain collation with high accuracy between seal prints of different levels of density by giving photoelectric conversion to a seal print on the paper to form plural collation patterns of different levels of density, and comparing these patterns with a registered pattern. CONSTITUTION:The reflected light sent from a seal print registered original 2 illustrated by a light source 1 is detected by an image sensor 4 and stored together with the ID information corresponding to a registered seal print store area 14. Then an original containing a seal print to be collated is put into the position of the original 2 and detected by the sensor 4. The seal print information is fetched by a seal print segmenting circuit 8 with plural fetching levels set previously and stored to fetched seal print store areas 10-12 respectively. The information of the area 10 is first read out and supplied to a comparator 15 to be compared with the registered seal print information which is stored to the area 14 together with the ID information. Then the information of areas 11 and 12 are successively read ouf for comparison. Then the maximum similarity is selected for collation. Thus it is possible to perform collation between seal prints of different levels of density with high accuracy.

Abstract: PURPOSE:To improve the characteristics of a chromafringe and to reduce cross color by using a band limit circuit with single tuned configuration and providing the frequency characteristics of a carrier chrominance signal outputted from the band limit circuit with a prescribed band width from the center frequency. CONSTITUTION:A color synthesizing video signal S4 is outputted from a 1st video amplifying circuit 4 connected to a video detecting circuit 3 and inputted both a 2nd video amplifying circuit 5 and a band limit circuit 8 with single tuned configuration. The circuit 8 determines resonance frequency and outputs a carrier chrominance signal S7 with a prescribed band width. The signal S7 is inputted to a chromaticity circuit 10 through a demodulator 9 and an I signal SI and a Q signal SQ which are modulated by a chrominance subcarrier wave so as to have the frequency band of the chrominance subcarrier wave are fetched from the circuit 10 and inputted to a matrix circuit 11. On the other hand, a luminance signal S5 outputted from the amplifying circuit 5 is amplified by a 3rd video amplifying circuit 7 and inputted to the circuit 11. Thus, a delay line for the transmission system of the luminance signal S5 can be omitted, improving the chromafringe characteristics and reducing cross color.

Title: Color picture tube
Inventor: ARIMOTO NOZOMI
IPC: H01J29/07
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce weight of a picture tube by applying tension to shadow mask so that the tension becomes the specific ratio to the tension under which the movement of electron beams on a phosphor screen caused by thermal expansion of a shadow mask by the adsorption of electron beams is completely prevented. SOLUTION: When tension applied to a shadow mask is set so that the tension becomes 5-90% of the tension under which the movement of electron beams is completely prevented, the moving amount of electron beams on the phosphor screen caused by the thermal expansion of the shadow mask by the absorption becomes 10-90% that when the tension is not applied to the shadow mask, and irregular color is reduced to a level of paractically no problem. A mask supporting frame stretching the shadow mask having low strength and light weight can be used, and as a result, the weight of a picture tube itself is reduced.

Title: Main shaft speed stabilizing device for automatic tool exchanging device
Inventor: IWASAKI TOSHIOMI
IPC: B23Q15/00
Filed: 1983-03-19
Abstract: PURPOSE:To stabilize the main shaft speed even in case a rated revolving number is high and facilitate the exchange of tool by a method wherein a torque pattern cancelling a previously memorized load torque is added to a torque command during the exchanging operation of the tool in case an automatic tool exchange is effected during the rotation of the main shaft.

Filed: 1989-02-28
Abstract: PURPOSE:To reduce the size, weight, and cost by constituting surface acoustic wave resonators which differ in resonance on the same piezoelectric substrate and selecting one of the surface acoustic wave resonators among plural surface acoustic wave resonators by using electronic changeover switches. CONSTITUTION:Aluminum thin film electrodes 1b and 1c differs in shape slightly, so the resonance frequency of the surface acoustic resonator composed of the aluminum thin film electrode 1b and a piezoelectric substrate 1a is different from that of the surface acoustic wave resonator composed of the aluminum thin film electrode 1c and piezoelectric substrate 1a. Thus, plural surface acoustic wave resonators which differ in resonance frequency are constituted on the same piezoelectric substrate 1a and the electronic changeover switches 6 and 7 are used to select one surface acoustic wave resonator among the surface acoustic wave resonators. Consequently, the small-sized, lightweight surface acoustic wave oscillators which differ in oscillation frequency can be obtained.

Title: Concrete body mixed with magnetic substance for superconducting magnetically levitated railroad
Inventor: OZEKI MASANORI
IPC: B60L13/03
Filed: 1995-03-07
Abstract: PURPOSE: To increase the utilization factor of the generated magnetic line of force by mixing a magnetic substance for increasing permeability into a concrete body, using the horizontal plane including the central line in the vertical directions of a ground coil for levitation guide as a boundary plane, and setting the rate of the magnetic substance mixed into the upper-side concrete so that the rate is larger than the rate on the lower side. CONSTITUTION: A magnetic substance is mixed into a concrete body 3 in a running path. At this time, the horizontal plane including the central line in the vertical direction of a ground coil 5 for levitation guide is made to be the boundary plane. The rate of the magnetic substance, which is mixed into the upper-side concrete, is made larger than the lower-side rate. Thus, a superconducting magnet 8 receives the attraction toward the upper position. That is to say, a vehicle 7 receives the stronger levitation force than in the case of the constitution, wherein the rate of the magnetic substance mixed in the concrete body 3 becomes uniform. Therefore, the utilization factor of the magnetic line of force generated from the superconducting magnet 8 is increased, and the levitation/guiding force and the propulsing force can be increased.
