Title: Electric power amplifier
Inventor: SHIYOUJI MASASHI
IPC: H03F3/20
Filed: 1979-04-11
Abstract: PURPOSE:To obtain a vertically symmetrical half-cycle output waveform by inserting a transistor which has the emitter and the base connected to the collector of a transistor for bias and the connection point of two resistances and has the collector connected to the power source terminal in DC. CONSTITUTION:Since the base current of transistor TR23 is supplied from power source terminal 2 through resistance 15, the driving current of output TR21 becomes 1/earth forward current amplification factor of the collector current of TR11 for bias, namely, the emitter current of TR23, and therefore, the driving current above becomes a very small value. Then, voltage loss for charging of bootstrap condenser 6 is reduced, and stored electric charge is increased considerably, and driving TR19 and output TR20 which are driven this electric charge can drive load resistance 8 sufficiently. Consequently, a vertically symmetrical half-cycle output waveform without distortion can be obtained from terminal 4, and further, a waveform with a large maximum output amplitude can be obtained.

Abstract: PURPOSE:To test each processing circuit simply and reliably so as to meet the request of a reduction in the size of the whole circuit in a semiconductor integrated circuit comprising a plurality of processing circuits, which respectively have a prescribed function. CONSTITUTION:When a mode setting signal for making a test for a processing circuit 8, for example, is inputted from an external terminal 13, a mode setting circuit 11 outputs a prescribed change-over signal 15a to a switch part 10a on the basis of the signal. As a result, a connection point A only of a programmable link 19a is connected to the circuit 8, the circuit 8 can transfer a signal to from the outside through a test bus 16a, an internal bus 18a and a buffer part 12 and the test of the circuit 8 becomes possible. At this time, a connection of buses is not made at a switch part 10b. Accordingly, the circuit 8 only is obliged to operate singly. When the test for the circuit 8 ends, a prescribed mode setting signal is inputted from the terminal 13 to enable the circuit 11 to output the prescribed change-over signal 15a and each connection point of the programmable link constituting the switch parts 10a and 10b is put in an unconnected state as in the case where the data of an EEPROM are electrically erased.

Title: Refuel control device
Inventor: KURIYAMA HISASHI
IPC: B67D7/30
Filed: 1991-03-11
Abstract: PURPOSE:To reduce troubles incurred by maintenance by detecting actual refueling quantity after the completion of refueling by means of preset refueling to determine a new adjustment quantity based on the difference between the actual value and preset value so that the new adjustment quantity is substituted for the adjustment quantity having been stored. CONSTITUTION:After refueling is finished, actual quantity of refueling detected at a refuel device 2b is read out to calculate the difference between this quantity and a preset value, wherein if the calculated value is equal to beta value which is an adjustment quantity of the fed oil quantity having been read out, it is confirmed that the refueling has been precisely performed. If not, error has occurred between the inputted refueling quantity and actual one, and hence the calculated value gives a correct beta value for a present pump. Therefore, the calculated value, as a new beta value, is compared with the previous beta value and if an absolute value of the difference is larger than 0.1 liter, the new betavalue is written into a memory region.

Title: Electro-optical distance measuring equipment
Inventor: TANAKA MASAYOSHI
IPC: G01S17/36
Filed: 1993-03-05
Abstract: PURPOSE:To provide a highly accurate electro-optical distance measuring equipment requiring no optical diaphragm. CONSTITUTION:An emitted intensity modulated light 4 modulated by a modulator 2 and having the same phase as a reference signal emitted from a light emitter 3 is passed through a transmission optical system 5 and reflected by an object 7 and then received, as a reflected intensity modulated light 10, by a light receiving means 11 through a light receiving optical system 9. The light receiving means 11 comprising an avalanche diode, for example, outputs a detection signal having externally controllable level which is controlled by a control means 15 to come within a predetermined range. A phase difference detector 14 detects phase difference between the reflected intensity modulated light 14 and the reference signal and a distance calculator 16 determines the distance. Since the level of detected signal is not susceptible to the quantity of light received by the light receiver 11, it is matched with that of the reference signal without requiring any optical diaphragm thus realizing highly accurate measurement.
