IPC: B41J2/175
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To eliminate waste of paper or ink by detecting the residual quantity of ink in an ink tank based on the weight of residual ink. SOLUTION: Weight of ink in an ink tank 2 decreases as the residual quantity of ink decreases through printing and the ink tank 2 is lifted by the spring force of a spring 7 while turning about a pin 6a, as a fulcrum. Consequently, the bottom part 2b is separated from a proximity sensor 8. When the separating operation is sensed by the proximity sensor 8, ink is supplied from an ink supply passage 4 into the ink tank. When the ink tank is fully filled with ink again, the ink tank 2 descend while turning and the bottom part 2b approaches the proximity sensor 8. When the approaching operation is sensed by the proximity sensor 8, ink supply from the ink supply passage is interrupted.

Title: Tape recorder
Inventor: HASEOKA MASAHIDE
IPC: G11B5/027
Filed: 1985-05-07
Abstract: PURPOSE:To obtain a simple and inexpensive tape recorder which is also capable of dubbing by securing such a constitution where just a single reproduction amplifier is used and a reproduction level control means corresponding to the 1st or 2nd head can be selected with different logical commands of a control means. CONSTITUTION:A control means 20 delivers different logical commands in response to the reproduction state of the 1st or 2nd mechanisms 1 or 2. A selection means 11 selects the 1st or 2nd reproduction output level control means 9 or 10 in response to the logical command given from the means 20. Thus the means 9 or 10 can always be selected in response to the head at the reproduction side despite only a single reproduction amplifier 8 provided to the 1st and 2nd heads 3 and 4. Furthermore it is possible to secure a prescribed output level in a tape reproduction mode even though both heads 3 and 4 have the difference of reproduction sensitivity. In such a way, a tape recorder which is also capable of dubbing can be obtained with a simple constitution and at low cost.

Title: Array antenna device
Inventor: CHIBA TANEAKI
IPC: H01Q21/22
Filed: 1981-06-23
Abstract: PURPOSE:To realize the characteristics of an array antenna suitable for an ILS localizer by weighting current distribution ratios on the basis of the number of elements when the number of the whole elements is an even number. CONSTITUTION:The directional pattern EN of an array antenna is found from the current distribution factor An of each element. The current distribution factor An of each element is determined by the function (f) of the directional pattern. Since the number of elements of the array antenna is finite, the function (f) is generally uncontinuous. Therefore, the directional pattern is adjusted by the mean value method from the directional pattern EN and the current distribution factor An. A new directional pattern ENm is found from a new current distribution factor weighted on the current distribution factor An of each element found by converting the function (f) of the directional pattern through Fourier conversion. The new directional pattern has small oscillation and a clear beam shape and is suitable for a localizer having an effective course structure in a single frequency system.

Title: Circuit for preventing semiconductor device from overheat
Inventor: INOUE KIYOKAZU
IPC: H01L23/58
Filed: 1982-06-07
Abstract: PURPOSE:To prevent a semiconductor device to be monitored from thermal runaway by forming a temperature detecting transistor (TR) having at least one external terminal to be used as an output terminal on the same substrate as a semiconductor device. CONSTITUTION:If excess current due to the short circuit of a load or the like is flowed into a main TR1 when the TR1 is actuated by applying driving current to its base, heat is generated by the power loss. Simultaneously, a TR2 formed on the same substrate detects the temperature quickly and generates thermally excited leak current ICBO between its collector and base and the curent ICBO is amplified by the current amplification factor hFE of the TR2 itself and taken out as the leak current ICEO between the collector and emitter. At the time, the leak current ICEO is increased at the rate of exponential function in accordance with temperature and suddenly increased at a temperature T. Since the temperature T is determined by ICBO and hFE, it can be selected optionally by controlling the ICBO and hFE.
