IPC: G01N23/20
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a sample high-temperature device by which the temperature of a sample can be controlled in an oxidizing gas atmosphere, a reducing gas atmosphere and other various gas atmospheres irrespective of the characteristic of a heating element. SOLUTION: The sample high-temperature device is used to change the temperature of a sample S. The sample high-temperature device is provided with a protective tube 8 which surrounds the sample S, which transmits heat and through which a gas is not permeated and with a heater wire 22 which is arranged and installed at the outside of the protective tube 8. The protective tube 8 is heated by heat from the heater wire 22, and the sample S is heated by heat from the protective tube 8. The heating structure is a heating structure of indirectly heated type, and it can control a temperature in a state that the sample S as a whole is in a uniform temperature distribution as compared with a heating structure of directly heated type. In addition, since the sample S and the heater wire 22 are partitioned spatially by the protective tube 8, they can be placed in different gas atmospheres.

Title: Lithium ion battery charger
Inventor: NONAKA TOMOKI
IPC: H02J7/10
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a lithium ion battery charger where there are few integrated errors of charge currents, with a simple circuit. SOLUTION: A charge voltage detecting circuit 4 detects the voltage of a battery, and a charge current detecting circuit 5 detects the voltage proportionate to a charge current. A control logic circuit 8 performs the abnormal check of the battery voltage and the control on the preliminary charge of a constant current by a very small current and the quick charge. In the quick charge, it performs the constant current charge by a charge maximum current until the battery voltage reaches the full charge level, and then, it performs the constant current charge by the charge current being reduced in phases each time the battery voltage reaches the full charge voltage, and when the charge current reaches the charge completion current value, the charge is finished.  Since the feedback circuit to an output drive circuit is composed of only a constant current control circuit, the circuit constitution becomes simple, and the quantity of the charge current being reduced in phases is clear, so the temporal integral value of the charge current can be obtained accurately.

Abstract: PROBLEM TO BE SOLVED: To set time required for a base film to pass a dry part to be almost equal, even with different device region length, when related to manufacturing of TCP, drying a resin film coated to seal a semiconductor chip mounted in each device region of a long base film. SOLUTION: Six nozzles 61 are used to coat resin, if the length of a device region corresponds to, for example, three times the pitch of the sprocket hole of a base film 11, while three nozzle 61 are used to coat resin, if it corresponds to, for example, six times the pitch of sprocket hole.

IPC: H02M3/28
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To enhance safety by arranging a circuit for interrupting a primary switching element of a converter when a control current flowing through an element in a control circuit is interrupted by detecting the DC secondary output voltage of a converter transformer so that the DC secondary output voltage can be feedback controlled. SOLUTION: DC secondary output voltage of a converter transformer is detected by comparing a voltage divided through voltage dividing resistors 8, 9 with a reference voltage produced through a Zener voltage establishing resistor 16 and a Zener diode 7. When a photocoupler is employed as an element in a control circuit, current flowing through a light emitting diode is interrupted. In this regard, a circuit for interrupting a primary switching element of a converter is arranged. Since the DC secondary output voltage can be feedback controlled through a simple arrangement, overcharge due to failure of a battery charger, i.e., the element in a control circuit, can be prevented resulting in a ringing choke converter circuit excellent in safety.
