Title: Acceleration indicator to following vehicle
Inventor: MISAWA KENICHI
IPC: B60Q1/44
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To reliably detect the deceleration and acceleration of a running vehicle and indicate it so as to be visually recognized by passengers in following vehicles or other with ease. SOLUTION: An acceleration indicator means 9 arranged at the rear of a vehicle has lamps 1 to 8 symmetrized left and right to have gradually-varied sizes. The lamps are adapted to be successively turned on in warm color from 1 to 8 as the deceleration gets larger and in cold color from 8 to 1 as the acceleration gets larger, to thereby provide images of coming nearer or going away farther for passengers in following vehicles.

Abstract: PROBLEM TO BE SOLVED: To rotate effectively for cleaning on a rug by forming a guide port that guides air to a main body of suction device which keeps a rotary brush in the storage room for the blade of a rotary brush and setting the block control mean that brakes the air flow. SOLUTION: The main body of suction device 1 has an upper case 2 and a bottom case 3, and keeps a rotary brush in the rotary brush storage room 8 on facing a suction opening 7 on the bottom of the main body of suction device 1, that consists of a pair of brush body 17 and a pair of blade 18. In this case, it is formed an guide port 22 in cross direction on the upper case 2, and an intake port 23 which is possible to block with a block body 24 on the cover body 4. When the suction opening 7 is blocked with a rug on cleaning, the block body 24 is deformed to the rotary brush storage room 8 side as the pressure in the rotary brush storage room 8 fails. And outside air sucked from the intake port 23 comes into collision with the brush body 17 and the blade 18 through the guide port 22 to rotate a rotary brush 13 effectively.

Filed: 1990-10-01
Abstract: PURPOSE:To decrease exit light and to obtain the device for a scanner having high reading accuracy by dividing the exit light of a lens array to components in two directions according to a vibrating direction. CONSTITUTION:The reflected light of an original is usually irregularly polarized light and has the vibrations equiv. in respective directions. The irregularly polarized light passes the lens array 21 and enters a polarization beam splitter 22. The other direction component light S reflected by the splitter 22 is made incident on a line sensor 23 and the one direction component light P transmitted through the splitter 22 is made incident on a line sensor 24. The output signals of the sensors 23, 24 are inputted to a plotter, by which the original information is reproduced as a reading signal. The transmittance and reflectivity of the wavelength region for separating the light to the light component P and S are made into nearly 100% by the adoption of the polarization beam splitter 22 and the ratio of the transmittance and reflection to incident light is nearly >=0.85. The ratio of the separated light P and S is 1:1 and, therefore, this device is advantageous for the processing of the outputs of the sensors 23, 24.

Title: Character segment system
Inventor: ISHIGAMI MASAYUKI
IPC: G06K9/34
Filed: 1985-11-20
Abstract: PURPOSE:To segment a character speedily and stably and to speed up the character recognition processing by calculating a character segment position from the vertical project of a character string pattern on the 1st line and segmenting characters on lines hence onward. CONSTITUTION:Character images of one line on a slip are coded into a binary pattern, and stored in a line buffer 1. Simultaneously a binary pattern signal is given to a vertical project generation part 2, and the vertical project of character patterns of one line is generated. A reference segment position calculation and correction part 4 calculates and holds the character segment position of only the character pattern on the 1st line from the vertical projection. On the other hand, a character segment part 3 segments a character one by one in accordance with the segment position whenever the character pattern of one line on the slip is stored in the line buffer 1. After a recognition part 5 extracts the feature of the character pattern, it collates the feature with a feature dictionary and recognizes the character. By storing the segment position, the calculation of the position with respect to character strings on the 2nd and subsequent lines can be omitted, thereby segmenting characters quickly.

Abstract: PURPOSE:To achieve a higher detection accuracy with an easier manufacture of a flow cell by forming a sample passage with a circular cross-section thereof to pierce the flow cell parallel with first and second sides thereof while a refractive index of a flow cell base material coincides with or approximates to that of a liquid sample. CONSTITUTION:A base material 22a of a flow cell 22 is made of a transparent fluororesin having a light transmittance within 400-700nm (containing a wavelength of laser light) in a wavelength range of light and a refractive index of 1.34.

When the sample 2 is water or an aqueous solution, as the refractive index of water is 1.33, no lens effect due to the water 2 is caused within the passage 20. In addition, there is no reflected light generated on the boundary of the water 2 and the base material 22a. Furthermore, as a light beam in the luminous flux 6 is roughly orthogonal to sides 22b and 22c of the cell 22, there is no reflected light generated as being incident into a light receiving section 8.

IPC: G11B21/08
Filed: 1986-10-31
Abstract: PURPOSE:To obtain correct digital information by changing a sampling period in accordance with a travel speed when a magnetic head is moved in a magnetic disk radius direction. CONSTITUTION:A period generating means 7 generates a sampling signal having a period approximately in inverse proportion in accordance with the size of the travel speed of a disk 12 radius direction of a head 1. The means 7 outputs the sampling period to a sawtooth generating circuit 5 by stages and generates the slicing signal of the same period as the sampling signal. A slicing voltage control means 11 adjusts the gain of the circuit 5 corresponding to the period of a sampling signal outputted from the means 7 and controls the voltage of a slicing signal outputted from the circuit 5. By the constitution, when the head 1 is moved in the radius direction of the disk 12, a sampling period is made smaller in accordance with the travel speed. Thus, the correct digital information can be obtained.

Filed: 1985-11-22
Abstract: PURPOSE:To manufacture an InPMISFET whose current drift is extremely small, by specifying deposition temperature and a mol ratio of SiH4 and PH3, [SiH4]/[PH3], which are introduced into a reaction system. CONSTITUTION:In a process in which SiO2 containing phospharous is deposited on an InP or InGaAs substrate, the deposition temperature is kept higher than 400 deg.C, and the mol ratio of silane and phosphine is selected as smaller than 7. Accordingly, DELTAVFB can be less than 0.5V, so that a MISFET whose current drift is extremely small is obtained. When [SiH4]/[PH3] becomes larger than 7, DELTAVFB decreases rapidly and becomes less than 0.5V. In the case where the deposition temperature is higher than 400 deg.C, DELTAVFB becomes less than 0.5V all the same. In the case of DELTAVFB=0.5V, the amount of current variation of a MISFET is calculated as 5% of a drain saturation current, which is considered as the upper limit of practical use of an element.
