Title: Thermal printer
Inventor: FUJIKAWA YOSHITAKA
IPC: B41J2/36
Filed: 1981-05-20
Abstract: PURPOSE:To constantly uniformalize typeprinting density, even when a typeprinting speed is changed, without necessity of adjusting voltage to be charged to a thermal head, by controlling the temperature of a platen in response to the typeprinting speed. CONSTITUTION:A thermal printer utilizes the phenomenum that deep typeprinting density can be obtained, even if voltage to be applied to a thermal head 1 is small, by properly heating a thermal paper sheet 2, running on a platen 3, through the platen. That is, the output voltage of a constant-voltage power source 5 to be applied to a resistance heater 4 arranged in the platen 3 is controlled by a voltage-controlling part 6 which is driven by a signal from a typeprinting speed-detecting part 7, to hold the thermal paper sheet 2 at a proper temperature through the platen 3 (the thermal paper sheet 2 is held at a high temperature when the typeprinting speed is high, while it is held at a low temperature when the typeprinting speed is slow). In addition, a signal from a sensor 8 having detected the temperature of the platen 3 may be utilized to drive the voltage-controlling part 6, so that influence from the change of an atmospheric temperature can be eliminated.

IPC: H01F1/06
Filed: 1981-05-20
Abstract: PURPOSE:To improve magnetic characteristic by a method wherein the mixture constituted of a resin solubke in a solvent and the solvent thereof is mixed with  the powder of magnetic material, and next, another solvent insoluble in said  resin is added to deposit a component constituting of said powder and the resin  coating powder surface. CONSTITUTION:The resin soluble to the powder of magnetic material and solvent for magnetic material containing paints and the solvent of the resin are put in a bowl mill to prepare mill base by milling. Next, this mill base is stirred up with the gradual addition of other solvent mutually soluble to the solvent of resin not dissolving resin to deposit a component constituting of magnetic material powder and resin coating powder surface. After washing the deposit until the perfect removal of the solvent of the resin by the solvent not dissolving resin, the deposit is dried. Thus, dispersible magnetic material composition can be obtained which causes no change in magnetic characteristic under long storage.

Title: Printing system for impact printer
Inventor: KODA YUTAKA
IPC: B41J35/14
Filed: 1986-04-01
Abstract: PURPOSE:To provide a printing system for an impact printer which enables the useful life of an ink ribbon to be prolonged while enclosing the ribbon in a small-type ribbon cassette, by using an ink ribbon while switching the part to be used of a color part of the ribbon, which has a width equal to a multiple of the height of characters to be printed, through turning a ribbon cassette enclosing the ribbon therein. CONSTITUTION:A ribbon cassette 1 is so mounted that it can be turned in the directions of arrows A, with (left and right) shafts 5 on a carriage 4 as a center of turning. With the cassette 1 turned about the shafts 5, an ink ribbon 2 is displaced relative to a printing head 3 in the width directions thereof (directions of arrows B), whereby the part to be used for printing of the ribbon is switched. When the ribbon has two or more colors, the width of at least one color part is set to be a multiple of the height of characters to be printed, and the ribbon part to be used is switched in the range of each unit color. Accordingly, the useful life of the ink ribbon can be prolonged to a multiple of that of an ink ribbon having the same length, and since it is sufficient for the size of the ribbon cassette to be enlarged only by an amount corresponding to the increase in the width of the ink ribbon, there is no need for greatly changing a mounting method for the cassette.

Title: Suspension controller
Inventor: EGAWA KENICHI
IPC: B60G17/015
Filed: 1995-03-31
Abstract: PURPOSE: To prevent chattering for completion of initializing by measuring dropping time when power voltage drops to lower voltage than preset voltage, and judging it as initializing failure if the total of dropping time is beyond preset time for stopping initializing. CONSTITUTION: When power voltage is beyond preset voltage by an initializing means, a control system begins to initialize. If power voltage drops to lower than monitoring voltage which is lower than preset voltage during initializing, dropping time is measured by an initializing stopping means. When the total of dropping time is less than preset time, initializing continues by the initializing means. If the total of dropping time is beyond preset time, it is judged as initializing failure to stop initializing by the initializing means. It is thus possible to prevent initializing start and stop from being repeated.

Filed: 1982-05-10
Abstract: PURPOSE:To prevent overconcentration of mixture gas when a choke will function, by heating a bellows during cool time of engine thereby increasing the expansion of bellow previously and increasing the bleed air. CONSTITUTION:When the engine is cool and the cooling water temperature is lower than the setting temperature of a water temperature switch 142, said switch 142 will conduct to flow current from a battery 140. Consequently the contact of a relay 138 will conduct to supply current from the battery 140 to a heating member 136 thus to produce heat from said member 136. Consequently a bellows 110 is heated and expanded to displace a sleeve 124 to the right thus to increase camber of a reed valve 120 and to increase the bleed air, resulting in the overconcentration of mixture gas upon operation of a choke.
