Title: Recording head and thermal recording device using the same recording head
Inventor: OHASHI TETSUHIRO
IPC: B41J2/345
Filed: 1989-04-28
Abstract: PURPOSE:To bias the density of current conducted through heat generating resistant bodies and permit the representation of medium tone by a method wherein a second electrode, separated from a first electrode connected to one side of the heat generating resistant bodies and connected to two sides of the same except the opposing side of the same body which is connected to the first electrode, is provided in the title recording head. CONSTITUTION:Resistant bodies 3 generate heat by electric current which flows from a common electrode 12, impressing a voltage on the heat generating resistant bodies 3 respectively, to a signal electrode 1. Since the current, conducted through the heat generating resistant bodies 3, has a tendency to flow through the shortest part of a distance between electrodes, the temperature of an area (a) becomes high when an impressing energy is small. When the impressing energy is increased gradually, the area, whose temperature becomes high, is shifted in the sequence of c d e and, finally, all of the areas of the heat generating resistant bodies 3 become high-temperature areas substantially. Accordingly, the area of ink, molten and transferred in thermal transfer recording, is increased as such high-temperature area is increased. Recording density is increased linearly as the impressing energy is increased. According to this method, the area of the transferred ink may be controlled depending on the magnitude of the impressing energy whereby gradation may be represented while utilizing one dot as one printing element and medium tone recording of high resolution may be represented.

Title: Physical quantity detecting device
Inventor: SUGANO MASASHI
IPC: G01D5/24
Filed: 1981-07-09
Abstract: PURPOSE:To compensate the temperature characteristics of an electrostatic capacitive sensor for detection of a physical quantity such as pressure without a special temperature compensating element, by utilizing the temperature characteristics of the delay time of a circuit. CONSTITUTION:When transistors (TR)10 and 11 are changed to the turn-off state from the turn-on state, voltages of plus input terminals of voltage comparators 20 and 21 drop from a power source voltage VCC with a time constant determined by capacitors 8 and 9 of a pressure sensor 100 and resistances 12-15 and 16-19, and therefore, outputs of comparators 20 and 21 are lowered to the low level from the high level. When the output of the comparator 20 is inverted to the low level, TRs 10 and 11 are turned on again, and voltages of plus input terminals of comparators 20 and 21 become the voltage VCC again. Then, the output of the comparator 20 is inverted to the high level to turn off TRs 10 and 11, and this operation is repeated. The temperature characteristics of the sensor 100 are compensated by the time delay for the change of a TR22 from the turn- on state to the turn-off state, and the conversion to a DC voltage V0 is performed by a low-pass filter 23.

Title: Insulated dc-dc converter
Inventor: WATANABE MINORU
IPC: H02M3/335
Filed: 1978-09-04
Abstract: PURPOSE: To prevent a photo coupler from lowering its control accuracy due to time aging by operating the photo coupler in switching operation.  
     CONSTITUTION: The output of an AC signal generator OSC is applied to a second coupler light emitting diode LD2 to operate a phototransistor PT2 inserted into the input circuit of a triangular wave generator TOS to thereby intermittently operate a light emitting diode LD1 through a voltage comparator CMP. Since the phototransistor RT1 operates in response to the on-off time of the light emitting diode LD1 as above, the feedback gain of the constant voltage control is determined by the ratio of on time to off time of the photo coupler to be retained at its optimum value. Even if the photo coupler used for the constant voltage control occurs time aging at its current transmission rate, the feedback gain does not alter to thereby  prevent the photo coupler from lowering its constant voltage control accuracy.

IPC: H04N5/265
Filed: 1983-06-16
Abstract: PURPOSE:To prevent disturbance of synchronism attended with changeover by changing video image signals from each of plural video image signal sources being independent including a synchronizing signal and extracting selectively the signals. CONSTITUTION:In the state where a video image signal S1 obtained from a television camera 1 is extracted by a changeover circuit 4 and led out of an output terminal 5, a television camera 2 generating a video image signal S2 not extracted by the circuit 4 is synchronized with the camera 1. A vertical synchronizing signal V2 in the signal S2 is made synchronized with a vertical synchronizing signal V1 in the signal S1. Thus, the circuit 4 is changed over together with changeover circuits 6 and 13 so as to connect a moving contact 4c of the circuit 4 to a contact 4b. Even if the state is changed over into a state that the signal S2 obtained from the camera 2 is extracted by the circuit 4 and led out to the terminal 5, the disturbance of the vertical synchronism attended with the changeover is not caused in the video image signal obtained from the terminal 5.
