Title: Thermal head driving circuit device and printer
Inventor: TAGASHIRA FUMIAKI
IPC: B41J29/38
Filed: 1991-07-19
Abstract: PURPOSE:To obtain a thermal head of thick-film center type wherein it is not necessary to divide printing data into two at a control circuit. CONSTITUTION:A pulse conversion unit 1 and a power switch circuit 2 are provided at a thermal head. A control circuit applies a synchronizing signal PL to the pulse conversion unit 1 at the thermal head and applies a serial printing data synchronizing with the PL to a shift register. The power switch circuit 2 operates every time it receives a start signal START so as to switch to power source lines C1 and C2 in sequence and supplies supply voltage. The pulse conversion unit 1 outputs a clock pulse CP only when the serial printing data to be added to the shift register is a data for the power source line to which voltage is not supplied at that time, and the data is stored in the shift register.

IPC: B29C48/91
Filed: 1982-10-15
Abstract: PURPOSE:To improve the transparency, twistability, tear resistibility and charging preventive capacity of an elongated polyethylene film by adding 0.05- 2.0wt% part of a surface active agent to a kind of polyethylene of which melt flow ratio (MI10/MI2.16) is 7.5-15. CONSTITUTION:A surface active agent (e.g.; glycerine fatty acid ester, etc.) which has charging preventive effect and less bloom and bleed is added by an amount of 0.05-2.0wt% part to a kind of polyethylene of which density is more than 0.94g/cm<2> and MI10/MI2.16 is 7.5-15. This molten polyethylene is extruded from a T die and cooled and solidified on a cooling roll at 70-120 deg.C to obtain a non-elongated film, and after this non-elongated film is preheated up to 80- 130 deg.C by a preheating device composed of a heating roll and pinch rolls, the temperature of the resin is raised to 190-280 deg.C and molten resin is extruded from the T die to obtain an elongated polyethylene film. Although this film is excellent in transparency, twistability, vertical tear resistibility, etc., it is permissible to add a copolymer such as polybutadiene, etc. and polyethylene of low molecular weight, etc. as required to further improve such properties.

Filed: 1987-07-20
Abstract: PURPOSE:To obtain the excellent characteristic and reproducibility by forming a superconductor with the specific composition as a thin film on an oxide substrate with the composition of Dy2MCuO5. CONSTITUTION:A superconductor with the composition of LnM2Cu3O7-k is formed as a thin film on an oxide substrate with the composition of Dy2MCu5, where Ln is at least one kind among La, Nd, Pm, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, Y; M is at least one kind among Ba, Sr, Ca; and (k) is 0<k<1. An oxide made of the same or similar component element to the component element of the Ln-M-Cu-O composite oxide superconductor is used as the substrate material, thus the thermal expansion coefficients of the superconductor and the substrate are very close values. The thermal stress and thermal distortion are rarely generated between the substrate and the thin film, and the reaction between the substrate and the superconductor at a high temperature is prevented. The good superconductive characteristic can be thereby obtained stably.

Title: Drawing control system by xor mode
Inventor: IGARASHI TSUYOSHI
IPC: G06T11/40
Filed: 1985-08-20
Abstract: PURPOSE:To attain a picture processing method which has no omitted joining point of vectors at a necessary part when a closed pattern is drawn, by controlling the drawing of a start point at the joining point according to the tilt of two adjacent vectors. CONSTITUTION:The Y coordinates Y0 and Y1 of the start and end points of a vector are loaded on register 1 and 2 respectively. A comparator 3 compares both coordinates Y0 and Y1 with each other. Then coordinate tilt information Y0>Y1, Y0<Y1 or Y0=Y1 is delivered to a register 4. A decoder 6 reads out the tilt information from a register 4 and 5 and the tilt information of the register 4 is held by the register 5. Thus the register 5 always holds the preceding tilt information, i.e., the tilt information on the preceding vector. The decoder 6 knows vector changes from the tilt of the present vector given from the register 4 and the tilt of the preceding vector given from the register 5 for drawing control of a start point. Thus the drawing processing is possible with no omission of the vector at a desired position and the joining point of vectors.

Abstract: PROBLEM TO BE SOLVED: To provide a multi-input A/D converter and a multi-input A/D conversion method for realizing the high-efficiency and high-speed processing of A/D conversion by performing control so as to read digital signals at the time other than critical time bands before and after the edge timing of clock signals for sampling analog signals and outputting the digital signals. SOLUTION: At the time t4, since interruption signals inputted to a CPU become high in level, the CPU performs interruption processing, changes output enable signals to be active and reads the digital signals from an A/D conversion means. Since the timing of the time t4 is positioned outside the critical time bands before and after the time t3 at which the A/D conversion means generates the digital signals corresponding to the analog signals A0 and the time t5 for starting the sampling of the analog signals A1, the digital signals are safely read.

Title: Method for manufacturing electric motor
Inventor: MORIZAKI MASAHIKO
IPC: H02K1/06
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of an air gap by accommodating a rotor into a stator cylindrical space by tight insertion or press fit, fixing a bearing for supporting a rotor output shaft to a stator, and then setting the outer diameter of the rotor to a specific dimension that is slightly smaller than the diameter of the stator cylindrical space. SOLUTION: When a rotor is inserted into a stator, the outer diameter of a rotor 2 has a slight clamping margin for the inner diameter of a stator 1. Specifically, when the rotor 2 is to be inserted into the stator 1, a protrusion 5 where a clamping margin is added to an air gap is provided at the inner diameter of the stator 1 or the outer diameter of the rotor, press fit is conducted by utilizing the protrusion 5, and burning is made for example, by a laser after an electric motor is completed. Also, the temperature of the rotor 2 is maintained at a high value for the stator 1 and press fit is made by utilizing the difference in thermal expansion, and a prescribed air gap is achieved when the rotor is cooled and the temperature becomes identical to that of the stator due to shrinkage after the electric motor is completed.  The air gap can be set to a small value, thus achieving an highly efficient electric motor.

Title: Steering gear for vehicle
Inventor: SHIMIZU YASUO
IPC: B62D3/12
Filed: 1995-06-22
Abstract: PURPOSE: To judge inclined degree of a wheel only by looking at an angle of a steering wheel by setting a pitch of rack teeth so that the maximum rota tion angle of the steering wheel generating a maximum steering angle to a wheel is within one rotation on a single side in a rack and pinion steering gear. CONSTITUTION: In a front wheel steering gear, in a normal area of steering at the time of traveling at medium-high speed, a stroke of a rack shaft 5 to a steering quantity of a steering wheel 1 is made small compared with the time of a large steering angle, that is, a relatively large gear ratio area is provided, while the stroke of the rack shaft 5 is made large in a large steering angle range of the steering wheel 1 so as to be suited to perform large steering in low speed travel. Rack teeth 5a are formed at variable pitch in order to make the whole rotation angle of the steering wheel 1 small. That is, the pitch of the rack teeth 5a is made larger as it goes away from neutral so that a pinion 4 reaches the terminal end of the rack teeth 5a when it is rotated almost one round, thus affording a maximum steering angle.
