Title: Heat control method for thermal head
Inventor: WATANABE TETSUO
IPC: B41J2/345
Filed: 1986-06-10
Abstract: PURPOSE:To enable a high quality printing, by a method wherein a thermistor is mounted on a driver element driving a heating element to take out a detection signal on the basis of the temperature thereof and an input energy to the heating element is controlled according to the value of the detection signal. CONSTITUTION:In printing, a detection signal based on the temperature of the surface of a driver element 11 is taken out from a thermistor 12. The driver 11 heats for itself due to the conduction to a heating element 9 for heating the heating element 9. The temperature change of the surface of the driver element 11 is regarded as that of the vicinity of the heating element 9. In this manner, the detection signal taken out from the thermistor 12 immediately results in the value corresponding to the temperature change of the vicinity of the heating element 9. The feedback of the detection signal detected by the thermistor 12 based on the temperature of the surface of the driver element 11 is made to a control system, whereby an input energy to the heating element 9 is variably controlled according to the value of the detection signal i.e., the temperature change. Such a variable control of input energy is carried out either by varilably controlling the width of the conducting current to the heating element 9 or by controlling the value of the conducting current.

IPC: H03H7/24
Filed: 1977-11-09
Abstract: PURPOSE: To obtain an AD converter which can control the input range digitally without a number of precise resistors and analogue switches.  
     CONSTITUTION: Since resistance network 21 and input resistor 22 are constituted by R and 2R, the relation between voltage V 1  of analogue signal input 1 and output voltage VO of operational amplifier 10 is shown according to the state of current switches A 1  to A n  as follows; VO/V 1 =-1/[(a 1 /2 1 )+(a 2 /2 2 )+(a n /2 n )]=  -2 n /(2 n-1 a 1 +2 n-2 a 2 +...+a n ). However, 1 or 0 is used for a k =K=1 to n according to the truning-on and off of current switches A 1  to A n . Therefore, by controlling switches A 1  to A n  from the external, the ratio of VO/V 1  can be controlled within  the range from (-2 n /2 n -1) to (-2 n ) in 2 n-1 -number stages. That is, one of gains in  2 n-1 -number stages is selected according to the range of analogue signal input  voltage V 1 , and the output voltage of operational amplifier 10 is determined.

Title: Printing head for parallel dot printer
Inventor: AKIBA KIYUUZABUROU
IPC: B41J2/255
Filed: 1978-11-02
Abstract: PURPOSE:To miniaturize the power unit by arranging the second group of printing elements at a position which is deviated by a distance equivalent to n fold of the half dot space in the line direction or equivalent to n fold of the half paper feed peich in the row direction from the position of the first group of printing elements. CONSTITUTION:Printing elements mounted on the printing head are divided into two groups. The first group of the printing elements is arranged at the reference position while the second group of thereof is arranged at least in one of two directions, line and row from the reference direction. In the line direction, it is deviated by a distance equivalent to n fold (n is a positive integer) of the half dot space or in the row direction, by a distance equivalent to n fold of the half paper feed pitch from the reference direction. The conventional equipment has a shortcoming that the peak value of the solenoid drive power source to be fed the printing head with is unavoidably excessive since printing elements are often striken simultaneously due to its arrangement of the printing elements in one row at an equi-space along the printing direction. The arrangement according to the invention can reduce the frequency of the peak current generated so significantly to miniaturize the power unit.

Title: Masking mitigating method for automatic sound volume adjusting device
Inventor: TAKIZAWA TETSUYA
IPC: H03G3/32
Filed: 1981-08-31
Abstract: PURPOSE:To migigate masking, by discharging charges stored in a storage circuit, only when no effective signal exists in the output of an external noise detecting circuit and conducting a gate circuit only when the signal exists in the output. CONSTITUTION:Even if an output level of an external noise detecting circuit 12 intermittently decreases and an output level of an integration circuit 13 is lowered, since the output level of an integration circuit 14 drops more slowly than  the output level of the circuit 13, before the output level of the circuit 13 drops remarkably, the output level of the circuit 14 is larger than that of the circuit 13, and a gate circuit 17 is made nonconductive during this period, the output of the circuit 13 just before the output levels of the circuits 13 and 14 cross over is stored in a storage circuit 18, allowing to mitigate masking. If the output of the circuit 12 is temporarily at zero potential, the charges stored in the circuit 18 are discharged via a gate circuit 20, but this discharge time constant is suitably selected, allowing to mitigate masking similarly, without dropping the output of the circuit 18.

Title: Color liquid crystal display element and production thereof
Inventor: OGAWARA MASAO
IPC: G02B5/20
Filed: 1988-06-03
Abstract: PURPOSE:To prevent the damage of electrodes by rubbing and eventually the disconnection thereof by rubbing a 1st substrate in the same direction as the direction of the stripes of the transparent electrodes patterned on the 1st substrate. CONSTITUTION:Color filters are formed on the substrate and the transparent electrodes are formed thereon and are patterned to the stripe shape and are subjected to an orientation treatment by a rubbing method on the 1st substrate side. The orientation treatment is so executed that the rubbing direction of the 1st substrate is the same as the direction of the stripes of the transparent electrodes patterned to the stripe shape on the 1st substrate. The rubbing direction, therefore, coincides with the direction of the striped electrodes even if there is the ruggedness according to the presence or absence of the electrodes. The steps in the direction where the substrate is successively rubbed are substantially eliminated in this way and the disconnection of the electrodes is hardly generated.
