Title: Level detector and treating device using the same
Inventor: SHIRATO MASATAKA
IPC: G01B11/00
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of reading a shape so that the ruggedness on the surface of a letter is accurately detected without being affected by print on the surface of the letter. SOLUTION: A reading area 220 on the surface of a letter 200 is irradiated with illuminating light rays 410, 415 different in wavelength from diagonally above at the left hand side and from diagonally above at the right hand side respectively. Reflected light rays from the reading area 220 are separated into light ray 420 corresponding to the light ray 410 light ray 425 corresponding to the light ray 415 by a dichroic mirror 520, and imaged by CCD line image sensors 540, 545 respectively. Both the images obtained by the CCD line image sensors 540, 545 become the same, except that in parts having a difference in level, a contrast between light and dark is reversed.  Therefore, by obtaining difference for every for the two images, information other than that of the parts having the difference in level is offset and position information of the parts having the difference in level can be obtained.

Title: Color display member
Inventor: KOBU MAKOTO
IPC: B41M5/26
Filed: 1992-09-02
Abstract: PURPOSE:To make it possible to provide the clear contrast of colors, to make the thickness thin, to achieve light weight and to improve conveying property by constituting a thermochromic layer by regularly arranging thermochromic materials, which repeat the coloring and fading of blue, green and red, respectively. CONSTITUTION:A thermochromic layer 1, whose heating is controlled by the current conduction, is held between intersecting stripe electrodes 2 and 2'. which are provided so as to face each other. In the thermochromic layer 1, thermochromic materials 1B, 1G and 1R, which perform the coloring of blue (B), green (G) and red (R), are regularly arranged at the intersecting positions of the facing electrodes 2 and 2'. This state indicates the mosaic alignment. When the thermochromic materials 1B, 1G and 1R are made to be the round shape or the cylindrical shape and the colors are arranged, the part other than the round-shaped thermochromic material is the heat resisting, or colored or transparent resin or pneumatic layer. Especially, when the pneumatic layer is provided, the diffusion of heat between the thermochromic materials is prevented, and the bleeding of the colors is less.

Title: Video tape recorder
Inventor: KOBAYASHI MASAAKI
IPC: H04N9/84
Filed: 1984-11-07
Abstract: PURPOSE:To avoid cross color disturbance when reproducing by removing cross color components with a comb-shaped filter in such a recording speed mode that crosstalk signals are reproduced after part of recorded tracks is sequentially overwritten when recording. CONSTITUTION:The color video signals are inputted to the input terminal 1 and supplied to the luminance signal processing circuit 2 and frequency separating circuit 4. When the recording mode A (track pitch 58mum) is selected with the speed selector switch 21, the interlocked switch circuit 7 operates to select BPF5. In such a case, the carrier chrominance signal is low frequency converted and recorded on the magnetic tape 13. On the other hand, when the switch 21 is set to the recording speed mode B (track pitch 19.3mum), the interlocked circuit 7 operates to select the comb-shaped filter 6. In this case, since the pitch is 19.3mum, when part of recorded tracks is overwritten, the carrier chrominance signal with the cross color components removed is low frequency converted and recorded on the tape 13.

Title: Alarm for vehicle
Inventor: KIMURA ATSUHIKO
IPC: G01S17/93
Filed: 1994-09-29
Abstract: PURPOSE: To obtain an alarm for vehicle which can detect a vehicle among objects with high accuracy and can deliver an alarm appropriately. CONSTITUTION: When a thermal infrared element 13 detects the intensity of infrared rays received in front of a vehicle, a comparator 22 and a human body alarming/determining section 30 determines the type of an object depending on the detected intensity of infrared rays including the reflected wave from a forward object. A distance calculating section 26 calculates the distance to the forward object based on a value corresponding to the time to be elapsed before detecting a reflected wave after emission of the infrared rays. Based on the distance thus calculated, an alarm section 29 delivers an alarm appropriately and thereby a vehicle can be detected accurately among objects. Furthermore, since a thermal infrared sensor is employed, the wavelength characteristics have no effect on the sensitivity and both vehicle and human body can be detected using a single sensor.

Title: Culture medium for culturing animal cell
Inventor: KAJIWARA YASUMASA
IPC: C12N1/38
Filed: 1993-08-27
Abstract: PURPOSE:To obtain a material capable of promoting proliferating action on an animal cell by adding the material to a culture medium containing fetal calf serum (FCS) and manifesting the proliferating action of the animal cell comparable to that of transferrin by adding the material to a serum-free culture medium. CONSTITUTION:This culture medium for culturing an animal cell is obtained by blending a hemoferrum composition in which a part of a globin chain is removed from hemoglobin. Since the proliferating action on the animal cell is remarkably promoted by adding a trace amount of the hemoferrum composition to the culture medium containing FCS, the amount of the expensive FCS used can be reduced. The hemoferrum composition can be used in place of transferrin in a serum-free culture medium.

Filed: 1989-09-11
Abstract: PURPOSE:To improve the overall processing time of a system by updating a reading data control table for each end of a data reading process and also performing a data multiplexing process for each lapse of a fixed time. CONSTITUTION:The data on a disk device (1) 15 are read as long as the corresponding data is not being read by another program when a data reading request is issued to a data control means 13 from a program. Meanwhile the copy data of the corresponding one is read if this data is being read by another program and a copy is included in a disk device (2) 16. When the reading process is over, a table updating means 12 is started and the reading frequency is counted for each data. Then a timer 11 starts a data multiplexing means 14 every fixed time to multiplex the necessary data and to delete the undesired data based on the data on a reading data control table. As a result, the overall system processing ability is improved.

Abstract: PURPOSE:To prevent short circuit between two power sources by detecting phases of the sources, and controlling an turnover timing of a solid state relay according to the detection output. CONSTITUTION:Phases of power sources of 220V and 60V generated from a power transformer 3 are detected by means of a detection circuit 5, and the detection signal Sc is applied to a switch changeover circuit 6.

The signal S controls changeover timing of solid state relay SW1, SW2. It is thus possible to prevent short circuit between both power sources without a time when both power sources are put ON simultaneously.
