Patent JP-S5733832-A (JP)
Title: Output circuit
Inventor: HAYAMIZU SADAHIRO
IPC: H03K19/013
Filed: 1980-08-06
Abstract: PURPOSE:To realize a high output at a high speed, by connecting a PNP transistor in parallel to an NPN transistor for flowing out a current, which has been totem pole- connected, and making this PNP transistor execute a constant-current operation. CONSTITUTION:When the emitter area of an NPN transistor (TR)19 of the second constant-current circuit is made equal to the emitter area of an NPNTR20, the same current as a current flowing through a resistance 18 from an electric power supply terminal 2 flows to the collector of the NPNTR19. When the collector area of a PNPTR13 of the first constant-current circuit is made equal to the collector area of PNPTR16, the circuit is operated so that a current value which is equal to a collector current of the NPNTR19 is drawn out to the collector of the PNPTR13. Accordingly, it is operated as a normal constant-current circuit by compensating the shortage of hFE of the PNPTR13 and the PNPTR16. Therefore, not only high VDH is obtained at a high speed by an output terminal 4, but also there are no variations of a characteristic of an ''L'' level output current.

Title: Disk drive
Inventor: BELL R FRANK
IPC: G11B5/596
Filed: 1987-04-30
Abstract: PURPOSE:To remove an apparent position error by changing the format of the magnetic transition or magnetic zone written into a guard band and giving plural phases to a phase locking loop by the new guard band. CONSTITUTION:The format of a guard band is written together with two phases of the same phase magnetic zone as two phases in a servo code. Respective magnetic zones are arranged at the position separated in the circumferential direction of an adjoining track and the phase of the pulse read from the magnetic zone is mutually separated to 180 deg.. Since such the recording of two magnetic zones determines a magnetic cell on a servo disk, when the servo code of two corresponding phases is used to generate a position error signal, the influence due to a close guard band is the same concerning both phases of the servo code, and since the position error signal is the amplitude difference between two phases, the off-setting signal due to a near-by degree of the guard band is cancelled between both phases. Consequently, the apparent position error is eliminated.

Title: Television receiver
Inventor: KATSUMATA CHIYOTOSHI
IPC: H01J29/89
Filed: 1983-06-16
Abstract: PURPOSE:To maintain and improve the visibility of a picture displayed on a CRT even in the conditions in which ambient light violently varies by providing a filter that varies optical transmission factor according to the ambient light, on the front of the CRT. CONSTITUTION:A filter 4 is provided in front of the phosphor film 2 of a front face glass 1 of a CRT and a shadow mask 3 and has the characteristic of reducing optical transmission factor as ambient light increases. When the ambient light is bright, incident light E0 increases and the optical transmission factor T2 decreases. On the contrary, when it is dark, since E0 decreases and T2 increases, the T2XE0 value is not varied so sharply as compared with the case where T2 is fixed. As a result, the constant ratio is maintained almost constantly and the visibility of a displayed picture can be maintained for both strong and weak ambient light.

Title: Gas turbine control device
Inventor: NAGATA KAZUE
IPC: F02C7/057
Filed: 1990-04-24
Abstract: PURPOSE:To control temperature of a gas turbine in which a pressure of the exhaust gas of the gas turbine is varied largely by its practical use always to the fixed target value of inlet temperature by composing an exhaust gas temperature target value by a curve operated from a pressure corresponding to the turbine inlet equivalent pressure, such as a compressor outlet pressure and an exhaust gas pressure signal obtained from an exhaust gas pressure detector. CONSTITUTION:An exhaust gas pressure detector 22 is set at the exhaust gas outlet part of a gas turbine 1, and a pressure signal S22 detected by this is added to a target exhaust gas temperature setting curve so as to prepare an exhaust gas temperature setting signal S10 for temperature control and an IDV control exhaust gas temperature setting signal S13. In this case, a temperature setting curve in a temperature control setter 10 and a temperature setting curve in an IGV control setter 13 are set so as to seek an exhaust gas temperature target value from a compressor outlet pressure and the exhaust gas pressure at a fixed gas turbine inlet temperature. Thus, even if any of the combined cycle operation and a gas turbine single operation is selected, the target value of gas turbine exhaust gas temperature is automatically varied by a change of the exhaust gas pressure to realize a temperature control which does not deviate from the target of the inlet temperature.

Filed: 1985-05-22
Abstract: PURPOSE:To prevent the wasteful consumption of the electric power source by providing a timer circuit to time the time smaller than the searching period of all stations to be supervised after the response information is sent to the station to be supervised, and when the timer circuit is in the timing action condition, interrupting the supply of the electric power source to the receiving part to receive at least the call information. CONSTITUTION:In the polling transmitting system remote control equipment, when the calling information from a supervising station 1 is received, it is decided by a control device 6 whether the calling information is effective for the station to be supervised or not. After the supervising station completes the sending action of the response information, a timer circuit 7 is set by an output signal S1 of the control circuit 6 and the timing action is started. In such a way, when the timer circuit 7 starts the timing action, an output signal S2 from the timer circuit 7 comes to be an L level, and therefore, a switch circuit 8 is released, and the supply of the electric power source to a receiving part 5 is interrupted. Consequently, the action is executed so that the electric power source can be supplied only during the period when the effective calling information sent from the supervising station to the receiving part of the station to be supervised is received, and therefore, the power consumption can be decreased.
