Title: Information reader/writer for card type recording medium
Inventor: NAITO MASASHI
IPC: B42D15/10
Filed: 1989-05-15
Abstract: PURPOSE:To improve the security for the application of a recording medium by enciphering and decoding the information when this information is recorded and read respectively. CONSTITUTION:The insertion of a recording medium 1 is detected by an optical sensor PH1, fetched inside by a roll 103, etc., and detected again by an optical sensor PH2. Simultaneously, a punching means 104 which punches an information recording part 4 is provided between a roll 102 and the sensor PH2 together with a light emitting means 105 which heats partially an information recording part 2 with a laser beam. Then a magnetic sensor MR is provided to read the recorded information out of the part 4 together with the magnetic sensors MD1 and MD2 while read the recorded information out of the information recording parts 2 and 3. In this case, a decoding code having an algorithm adverse to the encipherement is used when the information is read out of the part 2 since the information recorded at the part 2 is enciphered. Thus the security is improved for the application of a recording medium.

The period T1 is rather short as compared with the period T. An AVR signal depends on a load side voltage.  A pause signal interrupts the supply of the AVR signal to a plurality of the switching semiconductor elements. When the AVR signal exists at the start end and the terminal end of the pause signal, the AVR signal has priority to the pause signal.

Title: Image forming device
Inventor: AZUMA HISAFUMI
IPC: H01J29/30
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device with high fineness, high color purity and high reliability, and with sharply reduced discharge to damage it by setting a conductor on a face plate to a specified distance or more from the outermost peripheral part irradiated with electron beams toward the side wall part. SOLUTION: A conductor on a face plate is set to have a distance W or more shown by W>=2αH from the outermost peripheral part irradiated with electron beams toward the side wall (wherein αrepresents a parameter depending on the structure of an image forming member on the face plate with α=0.6-1, and H represents the distance between the face plate and a rear plate). The distance W takes the maximum value represented by θ=π/4 and is obtained from W=2αH. Since the backward scattered electron beam generated in the peripheral part is re-landed in the distance of 2αH at maximum from the peripheral part, it never collides when an insulating part such as glass or the side wall part is absent within this range. Accordingly, the charge and discharge accompanying the release of secondary electron or gas can be reduced to provide a reliable device.

The inside of an apparatus is set to a high vacuum, and the surface of the sample is etched by an Ar ion gun 4. The surface is removed into a conical shape, its circumference is surrounded by a wall at a cross-sectional exposure angle θ as an angle of inclination, and an exposure width W is formed with reference to a film thickness D. Then, a primary electron beam which is emitted from an electron gun 1 is converged via a converging lens 2 and an objective lens 3 so as to be incident to the sample 7. Secondary electrons which are scattered from the surface of the sample 7 are detected by a secondary-electron detector 5, and Auger electrons are detected by an Auger-electron detector 6.  By using the exposure width W and the exposure angle θ which have been measured, the film thickness D is found by an expression of the film thickness D=Wtanθ.

Abstract: PURPOSE:To save the energy necessary for the operation of a membrane module setting a specified flow rate with a pump on the original liquid side, and setting a specified pressure with compressing force of the pump and pressure reducing force of a suction pump on the permeated liquid side. CONSTITUTION:The flow rate of the original liquid and the pressure difference of the original liquid at the membrane surface (pressure difference between the original liquid and the permeated liquid chamber in a module) are designated as I and P, and the pressure to be reduced by a suction pump 6 as -X. The pressure P1 to be increased by a booster pump 3 of the original liquid is suitably set to (P-X). The booster pump 3 of the original liquid is operated at the flow rate I and at the pressure to be increased (P-X) and the suction pump 6 is operated to operate the membrane module 1 (when the membrane is contaminated and the capacity is reduced to nil, the suction pump is operated at the maximum pressure to be reduced -X). Although a manual valve is usually used as a valve 60, a constant flow rate of the permeated liquid and a stable characteristic can be maintained by using a constant flow valve.

Filed: 1990-05-11
Abstract: PURPOSE:To enable the control of the dissipation speed of a liquid included in a gel by coating a silica gel bead with a polymer composition containing a water-insoluble alginic acid salt. CONSTITUTION:A silica sol having a pH of 8.0-8.5 and produced by mixing water glass with a mineral acid is ejected from a nozzle into air and the droplets are thrown into water and washed with water to obtain spherical silica beads 1 having particle diameter of 1-5 mm. The beads 1 are immersed in an aqueous solution of a water-soluble alginic acid salt or its mixture with a water-soluble polymer (e.g. PVA) to form a coating film of the polymer composition on the surface of the bead. The coating film is cured by throwing the beads into an aqueous solution of a water-soluble alkaline-earth metal salt to obtain a bead 1 coated with a polymer composition 2 containing a water- insoluble alginic acid salt. The bead 1 is thrown into an amphiphatic liquid (e.g. methanol) and left standing for 1-48 hr to substitute the water in the bead with the amphiphatic liquid.

Title: Electronic dictionary
Inventor: KUNISAWA KANJI
IPC: G06F17/28
Filed: 1984-06-14
Abstract: PURPOSE:To reduce the storage capacity of a using memory and the cost of an electronic dictionary by allocating a short coe to a character having high using probability and decreasing the number of bits when the equivalent words are totally coded. CONSTITUTION:When the words are supplied for their equivalents, the address of the corresponding equivalent stored in an equivalent word memory 1 is extracted out of a word-equivalent address table memory. Then the equivalent words are read out of the memory 1 according to the equivalent address and outputted. This outputted variable length code is converted into the character data of the original equi-length code by a decoding circuit 7 and based on a decoding table 8. Then the equivalents corresponding to the input words are displayed to a character display circuit 9. In other words, a Huffman coding method is applied to the memory 1. A short code is allocated to a character having high using probability. As a result, the number of bits is decreased when the equivalent words are totally coded. This can reduce the storage capacity of a using memory and the cost of an electronic dictionary.
