Title: Method for displaying abnormality generation history of robot
Inventor: TERADA AKIHIRO
IPC: G05B23/02
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality generation history display method which can concretely analyze the generation cause of an alarm by going back to the past from a time when the alarm is generated. SOLUTION: Torque commands or real current of robot respective parts against a servo motor are sampled at every prescribed set period Δt. Latest n-pieces of sampling data are always kept in a data storage file. When the alarm is generated, the writing of data which is obtained the latest is stopped and n-pieces of data before the alarm is generated are prevented from being carelessly rewritten. A data display processing is executed after the alarm is generated and n-pieces of sampling data or the square average, cube average or 10/3-power average are time-sequentially graph-displayed. Then, the generation cause of abnormality can be analyzed by going back to the past from time when the alarm is generated by the time width of n.Δt.

Title: Laser diode drive circuit
Inventor: AOYANAGI SHINICHI
IPC: H04B10/00
Filed: 1987-06-15
Abstract: PURPOSE:To drive a laser diode where an N-type conductivity region side is earthed and provide a laser diode drive circuit which is fit for a TTL circuit and is operated with a positive power source as well by using a high speed NPN transistor. CONSTITUTION:The N-type conductivity region side of a laser diode 11 is earthed and its P-type conductivity region side is connected to emitters of NPN transistors 21 and 22. The laser diode 11 is directly driven by the NPN transistor 22 and a constant current which is determined by a constant current circuit 47 flows through a PNP transistor 24. Since the control of the transistor 24 determines whether it allows currents to flow through the base of transistor 22 or transistor 37, this control makes it possible to perform a high speed operation. Further, as circuits are operated by a positive power source, the drive of the laser diode by the output of a TTL circuit makes the interface between the TTL circuit and laser diode drive circuit simple.

Title: Lighting circuit of laser diode
Inventor: MIYASHITA AKIRA
IPC: G11B7/125
Filed: 1989-06-12
Abstract: PURPOSE:To emit light with low noise stably by connecting a point in a circuit from a high-frequency current output terminal to a laser diode, with a power source terminal or grounding terminal through a resistor. CONSTITUTION:The high-frequency current output terminal of a high-frequency current superposed integrated circuit (HF-IC) 1 is capacitively connected to a terminal of a laser diode 4 through a capacitor 3, and connected to a power source terminal VDD through a resistor 2. The laser diode 4 controls the lighting level with a speed of a record readout signal according to a signal inputted from a signal terminal SIG through a buffer 5, and a high-frequency current is superposedly supplied to the laser diode 4 at the same time. As the output terminal off HF-IC 1 is connected to the power source terminal VDD through the resistor 2, the high-frequency current flowing in the laser diode 4 has a flat characteristic with respect to the oscillation frequency even if the oscillation frequency fluctuates because of the fluctuation of the power source voltage, etc., and it becomes possible for a stable high-frequency current to be superposed. And, this makes it possible to emit light with low noise stably.

Title: Etching of algaas substrate
Inventor: SHIMA AKIHIRO
IPC: H01L21/302
Filed: 1986-06-26
Abstract: PURPOSE:To change an etching rate ratio in accordance with composition of AlxGa1-xAs and to enable selective etching, by utilizing an etchant composed of aqueous solution of tartaric acid and H2O2 water and changing the mixing ratio of these components. CONSTITUTION:When an etchant has a composition ratio k of 0.2-0.5, etching rates of GaAs and of AlxGa1-xAs are approximately constant indenpendently from a mol fraction x of AlAs in the AlxGa1-xAs. As the composition ratio k is increased, namely, as the proportion of H2O2 water in the etchant is increased, the ratio of the etching rate of the AlGaAs to that of the GaAs is decreased. Further, the etching rate ratio is decreased also when the mol fraction x the AlAs in the AlGaAs is decreased. On the contrary, as k is decreased, namely, as the proportion of the H2O2 water is decreased, the etching rate ratio of the AlGaAs to the GaAs is increased. Consequently, k=0.2-0.5 can be considered as a boundary for discriminating a region where the AlAs in the AlGaAs is hardly etched from a region where the AlAs is not etched.

Title: Fan control device for air conditioner
Inventor: WATANABE MAKOTO
IPC: F24F11/04
Filed: 1986-06-27
Abstract: PURPOSE:To prevent cold air delivery at the time of stopping heating operation without impairing room temperature control function by causing a room fan to stop at the same time as the stoppage of the heating operation, and resuming the operation of the room fan after a set time period has elapsed from the time of the fan stoppage. CONSTITUTION:When the room temperature has reached a set temperature, a thermostat 1 is switched off to cause a compressor relay 2 to be deactivated. Because of this, the heating operation is stopped, and a fan motor 3 stops blowing air. At the same time, a timer relay 4 starts counting time, and, upon counting a set time, closes a contact 4a. The power source is, then, connected to a terminal L for low speed operation of an fan motor 3, and it starts the operation at a low speed. Then, light breeze is blown from the air conditioner to circulate the room air to the temperature sensor section of the thermostat 1 to allow the room temperature to be again detected. When the room temperature becomes lower than the set temperature, the thermostat 1 is again switched on to activate the compressor relay 2 to resume the heating operation.

Abstract: PURPOSE:To provide a rice-cooker wherein magnetic flux is not leaked even if a magnetoproofing plate is omitted by forming an outer frame wherein the magnetic flux from an induction coil is not leaked to the outside of a main body. CONSTITUTION:This rice-cooker is provided with a rice-cooker main body, a lid body 9 covering the opening part of the main body 1 and being opened and closed by a hinge mechanism 1 as a support, an inner pot 2 stored freely removably in a main body 1, an induction coil 4 for heating the inner pot 2 by means of electromagnetic induction action and an outer frame 8 covering the inner pot 2 and the induction coil and forming the main body.

Abstract: PURPOSE:To sufficiently recover the amount of developer in a first developing tank by controlling a developer supply means from a second developing tank to the first developing tank based on the amount of developer in the first developing tank. CONSTITUTION:The developer supply means 71e from the second developing tank 71 to the first developing tank 72 is driven and controlled only while the amount of developer in the first developing tank 72 is reduced. For example, the developer supply means 71e is controlled based on the output of a means 74 which detects the height of a liquid level in the tank 72. In such a way, since the recovery of the amount of developer in the first developing tank 72 can be sufficiently performed even when an image forming operation is performed in a short period, it is possible to prevent a state where the amount of developer is insufficiently supplied to a developing apparatus when the next time of developing is started due to the insufficiency of the developer in the first developing tank 72 occurring.
