Title: Object lens drive unit
Inventor: HOTTA HISAYA
IPC: G11B7/09
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To suppress the tilt of a lens holder at the recording/reproduction of an optical disc with a relatively simple construction. SOLUTION: An object lens drive unit has an electromagnetic force producing means which drives a lens holder 12 by which an object lens 11 is held at least in a tracking control direction by an electromagnetic force. Holes 24 are drilled in the yoke 20b of the magnetic circuit of the electromagnetic force producing means and notches are formed in the magnets 19a and 19b of the means in order to make the distribution of the density of flux generated by the electromagnetic force producing means approximately uniform in a range having influence upon the lens holder.  With this constitution, even if the center of the driving of the lend holder and the center of the flux density of the magnetic circuit do not agree with each other, the electromagnetic force applied to the lens holder can be approximately uniform, so that the inclination of the lens holder from the surface of an optical disc can be suppressed.

Title: Vehicle running control device
Inventor: YASUKAWA TAKESHI
IPC: F02D41/00
Filed: 1987-06-08
Abstract: PURPOSE:To enhance the safety of running control by forcibly retarding the vehicle speed when a vehicle runs on a curved road, and by releasing control of running in association with the operation of a brake switch. CONSTITUTION:A control unit 10 receives an inter vehicle distance, a vehicle speed and a steering angle from sensors 1, 3, 5. Further, the control unit 10 detects a curved road when the steering angle exceeds a reference value, and selects a constant speed mode or a speed retardation mode in accordance with the turn-on and -off of a resume switch 9. In this arrangement, when a lateral acceleration of a vehicle detected by a sensor 4 exceeds a reference value, the control unit forcibly selects a speed retarding mode, irrespective of the turn-on or-off of the resuming switch 9. Further, when a brake switch is turned on all control modes are released. Further, an acceleration slip detected by a sensor 30 exceeds a predetermined value, a brake control device 14 is actuated.

Abstract: PURPOSE:To permit the safe and sure ignition from the primary ignition agent to the secondary ignition agent by improving the thermal sensitivity in the outside heating, by arranging the primary ignition agent in the space which is formed by a sealing member and a recessed part having an opened port part outside a gas generator casing body. CONSTITUTION:When the gas generator casing body 12 of a gas generator 10 is heated from outside, for instance in the scrap processing of automobiles by combustion, the primary ignition agent 60 in an automatic ignitor 50 is ignited at the temperature below the temperature where the mechanical strength of the gas generator casing body 12 reduces, and the pressure in a recessed part 54 increases, and the bottom part 62 of the recessed part is broken and a part of an airtightness holding container 24 is broken, and the secondary ignition agent 22 is ignited. Then, similarly to the ordinary collision, the gas generating agent 36 is ignited, and the gas is liberated, and the gas in which residue is removed is liberated outside the gas generator 10 from a gas discharge hole 46. With this constitution, the trouble that the mechanical strength of the gas generator casing is reduced by the outside heating and the casing is destroyed and forms broken pieces scattered on the periphery is prevented.

IPC: H01C7/00
Filed: 1977-11-29
Abstract: PURPOSE:To improve the disadvantage that when pulse separation is shorter the temperature of heating portions keeps rising and make the thermal head suitable for high speed recording by reducing the temperature fall time of the heating resistor of the thermal head by utilization of electrostatic cooling effect. CONSTITUTION:When the driving signal of a thermal head is inputted to input  terminal 4, a switching circuit 3 goes ON. Power is then selectively inputted to the  heating resistor 1b of the head part encircled by a broken line 1, from a driving  power source 2. A one-shot multi circuit 7 detects the fall of the input signal to the terminal 4 and the output pulse thereof turns ON a switching circuit 6. A DC high voltage power source 5 causes DC discharging to be started between the resistor 1b and its electrodes 1c, 1d and a needle form electrode 1e with a grazed ceramic substrate 1a in-between, then the high temperature part causes rapid temperature fall owing to electrostatic cooling effect. This DC discharge time is so set as not to hamper the next temperature rise.

IPC: G06F17/21
Filed: 1995-06-09
Abstract: PURPOSE: To efficiently decide a character kind in an inputted document image and improve the process precision of a character recognizing process by deciding the character kind of a line of interest according to line height, the number of characters, and the width of a tentative character detected by a detecting means. CONSTITUTION: A bit map image inputted through an image scanner 6 is divided into blocks first. When a block to be processed at present includes characters, the data in the block are projected on a Y axis and the lines where the characters are present is extracted. Then respective lines are projected on an X axis and the characters are segmented. It is judged whether or not the longitudinal/lateral ratio of the character width and height of each character is larger than a previously set threshold value. When the judgement result is affirmative, it is judged that the line of interest consists of Japanese characters and the character recognizing process is instructed to refer to a Japanese dictionary or recognize the characters by referring to it preferentially.  When the judgement result is inaffirmative, on the other hand, it can be judged that the line of interest consists of English characters, so the recognizing process is instructed to refer to an English recognition dictionary or perform the processing by referring to it preferentially.

IPC: G06F11/10
Filed: 1995-06-09
Abstract: PURPOSE: To easily and fast calculate the checksum value by updating a data item against a data item changing command based on the relative change between the unchanged and changed data items and also updating the checksum value based on the relative change of the data items. CONSTITUTION: A database stores the data items A, B and C and also the checksum value (A+B+C) corresponding to the items A to C respectively. When the database starts the relative change processing of the data items, e.g. (A→A+1), the changed data item is updated to (A→A+1) based on the relative change +1 between unchanged and changed data items. Then the checksum value is updated based on the relative change of the data items. In other words, the value +1 obtained based on the relative change of the data item is added to the value (A+B+C) corresponding to the items A to C. Thus (A+B+C+1) is obtained.

Abstract: PURPOSE: To effectively dehydrate a coal-water slurry to a moisture content usable as a fuel, by a method in which a coal-water slurry is concentrated and classified, and then coarse coal particle slurry is dehydrated mechanically and water in fine coal particle slurry is replaced with a water-soluble, combustible low-boiling medium which is in turn removed.  
     CONSTITUTION: Coal used in steam-power plant, etc., is usually pulverized, suspended in water to a slurry, and then transported in order to raise the efficiency of transportation. In the dehydration of the coal-water slurry to a proper moisture content usable as fuel, the supernatant of the slurry is removed at a coat storage process and then classified into a slurry 5 consisting of coarse coal particles of more than a given size and a slurry 6 consisting of fine coal particles of less than a give grain size in a classification process. Then, the slurry 5 is dehydrated mechanically and water in the slurry 6 is replaced with a water-soluble, combustible low- boiling medium to form a fine coal-low-boiling medium slurry 12. Then, the slurry 12 is deprived of its medium contained at a medium-removing process. Thus, the dehydration of coal can be effectively attained.
