Title: Interpolation system for character pattern deformation
Inventor: ISHIZU TAKAYUKI
IPC: G09G5/24
Filed: 1989-02-14
Abstract: PURPOSE:To interpolate the breaking of a line due to deformation processing automatically and to improve the character quality after the deformation by comparing the dot pattern of each line with that of its last line and detecting the breaking of a line of a character pattern, and adding specific interpolation dots according to the line breaking state. CONSTITUTION:The quantity of inclined character deformation corresponding to the deformation angle of a character pattern is set in an inclined character deformation quantity register 31 and a relative deviation quantity arithmetic circuit 32 calculates the quantity of relative deviation of each line from a last line to generate a relative deviation quantity table 33. An inclined character deformation circuit 35 reads character pattern data before deformation out of an image memory 34 and refers to the relative deviation quantity table 33 to perform deformation processing, line by line. Then the dot pattern of each line is compared with that of its last line and when the breaking of a line of a character pattern is detected, specific interpolation dots are added corresponding to the line breaking state. Consequently, the line breaking is interpolated automatically to improve the character quantity after deformation.

Title: Self pumping type shock absorber
Inventor: TAKEMA SHUICHI
IPC: F16F9/44
Filed: 1995-01-31
Abstract: PURPOSE: To surely prevent a pumping reaction from increasing by providing an outlet passage for guiding a working fluid to a high pressure chamber and a going and returning passage for guiding the working fluid in the high pressure chamber to a working fluid chamber in a shock absorber and a variable throttle device for controlling the level of communicating of the going and returning passage in the middle way thereof. CONSTITUTION: By increasing the capacity of the pump chamber 54 of a pump 140 during the extension stroke of a shock absorber, a suction valve 64 is opened and oil is sucked from a low pressure chamber. By increasing a pressure in the pump chamber 54 during the contraction stroke of the shock absorber, a discharge valve 80 is opened and oil in the pump chamber 54 is discharged to the liquid chamber 124 of an accumulator 18. In this case, since the increase/ decrease of damping force is controlled by driving a variable throttle valve 132 by means of an actuator 134 and oil is supplied without passing through the variable throttle valve 132 during the contraction stroke of the shock absorber, the increase of a pumping reaction is prevented.

Title: Motor control circuit
Inventor: OKUMURA YOSHIHIRO
IPC: H02P7/288
Filed: 1987-02-18
Abstract: PURPOSE:To simplify the configuration of a driving mechanism section by extracting a pulsating component generated upon the rotation of a motor, and discriminating whether the motor is rotated. CONSTITUTION:When a motor 22 is driven, a pulsating component is generated in a driving current by brushes and a commutator. The pulsating component is applied through a current/voltage converter 27, a high pass filter 28 and a diode 29 to an integrator 32. An operational amplifier 33 compares an input voltage V1 from the integrator 32 with a reference voltage Vf from a reference voltage source 34, and outputs a signal for stopping the power energization of the motor 22 by a driver 25 when the voltage V1 becomes smaller than the voltage Vf. Thus, it is not necessary to provide a limit switch in a driving mechanism section.

Title: Distribution type fuel injection pump
Inventor: ICHIKAWA TATSUYA
IPC: F02M41/12
Filed: 1995-02-23
Abstract: PURPOSE: To enable an engine to quickly stop after stopping fuel supply thereto as well as to increase a fuel sucking quantity into a pressure chamber. CONSTITUTION: Two fuel sucking holes 32 for communicating a communicating part 21 formed on the outer wall part of a plunger barrel 20 with a barrel inside hole 20a are formed in both end positions in an angular range of the communicating part 21 and always communicating with each other through the communicating part 21. Each fuel sucking hole 32 comprises a sucking port 33 and a sucking slit 34 and a volume reducing member 30 is received in each sucking port 33. Each fuel through hole 31 formed in the volume reducing member 30 continues to the communication part 21 and the sucking slit 34. Since the fuel is sucked into a pressure chamber from two fuel sucking holes 32, the fuel sucking quantity is increased.  Furthermore, since the volume of the sucking port 33 is reduced by means of the volume reducing member 30 and the fuel quantity sucked into the pressure chamber becomes small after a fuel sucking-in passage is blocked, the engine stops quickly.

Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency with a low loss and raise the safety against the thermal runaway due to self heating by adding BeO at a specified mol.% or less. SOLUTION: Fe2O3, NiO, ZnO, CuO and BeO are weighed and mixed for 2 hrs., using an attritor, and granulated by a spray drier, the granulated powder is prebaked in a rotary kiln, crushed by the attritor, granulated by the spray drier, pressed into a toroidal shape, and baked at 1200 deg.C. The main components are Fe2O3, NiO, ZnO, CuO but the same effect is obtained when using a Ni-Zn ferrite containing Fe2O3, NiO, and ZnO as main components. BeO is set to 20 mol% or less (not contg.

Abstract: PURPOSE:To facilitate the handling of a measuring instrument by placing a cathode-ray tube, whose panel surface facing downward, on a measuring instrument, whose measuring surface facing upward, so that the influence of the earth magnesium is eliminated and the electron gun subjected to a high voltage is not adversely affected. CONSTITUTION:A cathode-ray tube 1, whose panel surface 2 facing downward, is placed on a measuring instrument 3, whose measuring surface facing upward. With the panel surface 2 facing downward, the influence of vertical field of the earth magnetism is eliminated so that the positional relation between the phosphor and the electron beam is never changed, thereby more simple positioning adjustment of a deflection yoke 4 can be carried out. In addition, with the panel surface 2 facing downward, a foreign material in the tube becomes more liable to drop onto the panel surface 2 by the action of gravitation, so that dielectric strength deterioration is prevented. Further, it is only required to place the tube 1 on the measuring instrument 3 for mounting the tube 1 and special mounting force is not required because the gravitation g serves as the mounting force.
