Title: Label printer
Inventor: YASUI YUJI
IPC: B41J2/35
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To check wire breaking of a thermal head without requirement of a host, and thereby have no bad influence to the smooth issuance of labels by checking the wire breaking of a thermal head at the time of recognition of paper jam and label end. SOLUTION: The wire breaking check of a thermal head is conducted immediately after an initial process or cover close, and in either case, it can be done independently by a label printer 1 by no requirement of the host side. If it is carried out right after the initial process or cover close, i.e., since it is not during the issuance process of labels, such a wire breaking check of the thermal head does not adversely affect the smooth issuance of labels. Inasmuch as a cover 3 is opened and closed even when refilling or replacing a label roller or at the time of treatment of jam, the wire breaking check of the thermal head can be conducted at a certain frequency.

Title: Organic el element
Inventor: ARAI MICHIO
IPC: C23C14/06
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain an electronic element having high efficiency and a long life by providing an organic layer having a luminescent layer between a hole injecting electrode and an electron injecting electrode, an inorganic hole transporting layer with high resistance between the luminescent layer and the hole injecting electrode and an organic hole injecting layer between the inorganic hole transporting layer and the hole injecting electrode. SOLUTION: In this organic EL element, a base 1, a hole injecting electrode 2, a hole injecting layer 3, an inorganic hole transporting layer 4 with high resistance, a luminescent layer 5 and an electron injecting electrode 7 are laminated in this order, and a driving power supply E is connected between the hole injecting electrode 2 and the electron injecting electrode 7, to adjust the color tone of a luminescent color and to produce multiple luminescent colors. Since the organic EL element has the inorganic hole transporting layer 4, its heat resistance and weather resistance are enhanced, and a long life is given to the element. Its connectivity to an electrode of an inorganic material is excellent and production of a leakage current and a dark spot is suppressed.  A vacuum deposition method is preferably used to form the luminescent layer 5 and the organic hole injecting layer 3 because a uniform thin film can be formed, and excellent characteristics can be obtained by preventing the interface of each layer from adsorbing impurities.

Title: Operation control method of pump
Inventor: TSUKUI HIROMI
IPC: F04B49/06
Filed: 1981-05-12
Abstract: PURPOSE:In a pump facility equipped with a rotation controller for the city water and sewerage, to stabilize the operation irrespectively of the actual lift by calculating the actual lift and the minimum allowable rotation from the water level of a suction tank and a delivery tank and controlling the delivery of the pump. CONSTITUTION:The water level signals LP, LS detected from the water level meters 7, 8 in a blow tank 1 and a delivery tank 2 are inputted into a subtractor 11 to operate the difference between LP, LS or the actual lift Ha, and a function generator 12 will input the minimum rotation NL corresponding to the actual lift Ha to a correction arithmetic unit 13. While since a rotation command NS operated from a target flow QM and a delivery flow signal QS is provided from a flow regulator 10 to said unit 13, NS is compared with NL to brake a motor 4 through a rotation controller 6 such that NS will never be lower than NL. Consequently the delivery higher than the predetermined level can be assured for any actual lift resulting in the prevention of the pump efficiency.

Title: Switching power supply
Inventor: TOKUNAGA ATSUO
IPC: H02M3/28
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain a switching power supply stabilized over a wide range of fluctuation for different loads and supplying power stably even for dynamic fluctuation of a load. SOLUTION: In a switching power supply 10, a microcomputer 13 calculates a gain correction coefficient g (=PWMn-1/Ifb) based on a previous PWM duty PWMn-1 and an output value thereof, i.e., a current detection value Ifb and corrects a control gain G with the gain correction coefficient to determine a corrected control gain (=G/g). When the corrected control gain (=G×g) exceeds a predetermined value GSL, a corrected value Δ of PWM duty is calculated by substituting the predetermined value GSL for the corrected control gain (=G×g) and then the previous PWM duty PWMn-1 is corrected based on the corrected value Δ of PWM duty thus determining a PWM duty PWMn.

Title: Brushless motor protecting device

IPC: F24F11/871
Filed: 1989-03-23
Abstract: PURPOSE:To prevent rupture of a semiconductor switching group in a way that an overcurrent is prevented from flowing to the winding of a brushless motor by a method wherein when an air velocity value exceeds a specified value, on on-off means is turned OFF. CONSTITUTION:A thermistor 21 is mounted in a place where an external air force is exerted and a thermistor 22 in a place where no external force is exerted. Since a thermistor self-generating heat produces a difference in a radiation amount according to the presence of an external air force and a thermistor temperature is changed, a difference in a resistance value is produced. By comparing resistors 23 and 24 with a partial voltage by means of a comparator 25, it is decided whether an external air force exceeds a specified value. Since the thermistor 21 is mounted in a place where the external force is exerted, when an external air velocity exceeds a specified value, and when voltage division points V1 and V2 are compared with each other, the resistance value of the thermistor 21 is increased to a value higher than the resistance value of the thermistor 22. Thereby, V1 is higher than V2, an output from the comparator 25 produces 'L', and a relay 30 is brought into an OFF-state through monostable multivibrator 26 for a specified time.
