Filed: 1986-02-13
Abstract: PURPOSE:To enable high-speed and high-quality printing to the performed by covering an electrode layer and a glazed layer with a resistance heating element layer and further covering the resistance heating element layer with an abrasion- resistant protective layer to form a thermal head. CONSTITUTION:After forming an electrode layer 4 so as to cover a glazed layer 2, the part near a top area of the glazed layer 2 is truncated almost parallel with a substrate 1 so that part of the glazed layer 2 may be exposed. Because of this, the top surface of the glazed layer 2 is formed into an almost flat surface. Next a resistance heating element layer 3 is formed so as to cover the electrode layer 4 and the exposed glazed layer 2, and then the resistance heating element layer is covered by a protective layer 5 to form a thermal head. In this thermal head, the adherence between a thermal paper or a thermal transfer ink ribbon and the protective layer 5 is high. Therefore, heat generated in the resistance heating element layer 3 can be transmitted effectively to thermal paper through the protective layer 5.

Title: Elastic surface wave filter
Inventor: ASAKAWA KIYOSHI
IPC: H03H3/08
Filed: 1980-03-10
Abstract: PURPOSE:To reduce the transmission loss of an elastic surface wave when a higher harmonic wave action is utilized, by dividing one of a paired reed screen type electrode selectrodesinto the reed screen type electrode groups having a small number of  electrode fingers and distributing the transmission lines of each surface wave so that they never overlap with each other. CONSTITUTION:One or more pairs of reed screen type electrodes are formed on a piezoelectric substrate to satisfy a relation of p/lambda>0.5 between the length lambda of an elastic surface wave and the period (p) of the finger of the reed screen type electrode. Then one of a paired reed screen type electrodes is divided into the reed screen type electrode groups 23-27 having a small number of fingers. These electrode groups are distributed so that the transmission lines of the energized elastic surface wave never overlap with each other. For instance, the electrode pattern of the 3-fold higher harmonic surface wave filter using a double electrode is divided into the five reed screen type electrode groups 23-27 that are distributed as shown in the figure. Then the RF voltage is applied between the lead electrodes 21 and 22. As a result, each electrode group energizes the surface wave with the electrode  groups connected in series. This energized wave is received at a normal electrode 28.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To correct a DC component by detecting the size and direction of a DC component by interval-integrating a primary current of a transformer, deviating the zero point of an AC output voltage detected value in a direction of canceling the quantity of magnetic deviation, and definitely detecting the DC component contained in an AC voltage. SOLUTION: Instantaneous values of the primary currents Iuv ACL and Iwv ACL of a transformer are detected by interval-integration in synchronization with the power supply period of an output voltage power supply, and further the amount of voltage corrections Xuvb and Xwvb corresponding to the quantity of magnetic deviation is generated by averaging. Next, in a voltage detecting circuit, these amount of voltage corrections Xuvb, Xwvb and feedback values of Vuv, Vvw of output voltage at AC side are added together and the zero point of Vuv, Vvw of the output voltage detected values at AC side is deviated. That is, the zero point of the output voltage detected value can be deviated by the amount of voltage corrections as to cancel the magnetic deviation of the output voltage.  By this operation, the magnetic deviation of the output voltage at AC side can be restricted and a predetermined inverter output voltage can be obtained.

Title: Direct current feeding method
Inventor: ISHIBASHI MASAYUKI
IPC: H02M7/757
Filed: 1987-02-12
Abstract: PURPOSE:To carry out a constant voltage control and to reduce the cost of the feeder equipment, by installing power converting devices combining a direct power converter and an inverse power converter at the power line to combine plural tramcar trucks which are divided by dead section and an AD power source respectively. CONSTITUTION:At power lines combining plural tramcar trucks divided by dead sections and an AD power source, power converting units 22a are installed respectively. The power converting unit 22a is composed by connecting inversely parallel self-arc-suppression type semiconductor control elements such as a gate turnoff thyristor GTO, as well as thyristor SCRs are connected in three- phase bridging. Therefore, the current to an accident point of the tramcar truck can be cut off by the gate off control of the SCR, and a power running breaker is unnecessary. Furthermore, when a communication failure of the GTO control occurs, a regenerative breaker is unnecessary because the accident current breaking can be performed by giving the gate off signal to the GTO. Therefore, the equipment can be reduced, and a low cost is realized.
