Title: Reflow method and device therefor
Inventor: ABE NOBUHIDE
IPC: B23K101/42
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a reflow method and a device therefor by which an electric part can be surely soldered without affetcting it. SOLUTION: A work (w) coated with solder pasts is transferred by a transfer conveyor 7. In a furnace 8a, the temperature of the work (w) is increased to a room temperature in about 50 seconds, and the work (w) is preheated at about 150 deg.C for about 75±15 seconds in furnaces 8b and 8c. Then it is heated at about 230 deg.C for about 30 or 40 seconds in furnaces 8d and 8e and a solder paste is melted by reflow, and it is quenched by a cooling fan 9 and is soldered. The soldering temperature is kept in a range 5 or 10 deg.C higher than the liquidus of solder for 30 or 40 seconds, so that a semiconductor is hard to be affected at a high temperature and a melting time is made longer enough to permit the growth of alloy layer, thereby improving the joint strength and suppressing the production rate of lift-off.

Abstract: PROBLEM TO BE SOLVED: To secure the running performance and running distance of an electromotive vehicle even in a case when the ambient temperature is low, by controlling the tolerable maximum discharge current to the level where it does not reach the drive stop of load, in case that the detected battery temperature is at or under the set temperature. SOLUTION: The electric system 2 of an electromotive vehicle 1 is equipped with a controller 20, and it turns on a switch 3 by the command from a discharge control means 27, and a storage battery 4 performs discharge and supplies power to the load 5, but at the time of discharge of the storage battery 4, current information is sent to a battery current detection means 23 from a discharge current detector 8 so as to detect the discharge current. Battery temperature information is sent to a battery temperature detection means 21 from a temperature sensor 10 so as to detect the temperature of the storage battery 4.  Then, a judging means 22 judges the magnitude by comparing the detected battery temperature with set temperature, and a discharge current setting means 25 sets the tolerable maximum discharge current to the level where it does not reach the drive stop of the load 5 in case that the battery temperature is at or under the set temperature.

Title: Four-pole two-pair-driving electrostrictive rotor motor
Inventor: KUMADA AKIO
IPC: B60B1/06
Filed: 1989-12-28
Abstract: PURPOSE:To double the output torque by connecting a motor and a DC power source directly with a gate and employing the doubled-voltage driving method. CONSTITUTION:The four surface electrode pieces 2, 3, 4, and 5 and the four rear electrode pieces 6, 7, 8, and 9 of an electrostrictive disc rotor 1 are divided into four short-circuited pairs. In this time, the electric potential of the electrode 2 is the same as that of the electrode 5 in the first quarter of he period of frequency (f), as that of the electrode 3 i the second quarter, as that of the electrode 5 in the third quarter, and as that of the electrode 3 in the last quarter. Because the voltage applied between the four surface electrode pieces 2, 3, 4, and 5 and the four rear electrode pieces 6, 7, 8, and 9 is changed over alternately with frequency (f), the electric potentials of the electrodes 2, 3, 4, and 5 change every quarter of the period and act as a rotation electric field. Constant voltage V or -V is always applied between the surface and rear electrodes, doubling the action effect.

IPC: G06F17/21
Filed: 1989-12-28
Abstract: PURPOSE:To process the input/output documents of different systems in the same way as the documents of the same system by separating the control codes used to the documents of different systems out of a text and then converting these control codes by reference to a control code dictionary. CONSTITUTION:A document system is designated by a document system designa tion means 13 and a code separation processing means 15a separates the control codes from the document data of an input system by making a document system conversion means 15 refer to a control code dictionary 14. Then a code conver sion processing means 15b converts the separated control codes into those of an output system by reference to the dictionary 14. A code connection processing means 15c connects the control codes of the output system to each other to obtain the document data of an output system. Then the document systems are converted in the same process. Thus it is possible to perform the proper conversion processing of the document systems in a simple and sure way. At the same time, the input/output documents of different systems can be easily handled and obtained quickly. Then a specific conversion tool can be omitted to each document system.

Title: Controller for electric refrigerator
Inventor: YAMAMOTO IZUMI
IPC: F25D17/06
Filed: 1992-12-18
Abstract: PURPOSE:To simplify a control of a fan motor and an alarming means by a method wherein an output signal of a power source interval detecting means is inputted into a fan motor controlling part and a door open-and--close detecting and controlling part. CONSTITUTION:A photo coupler 4 used as a power source interval detecting means operates when a door is closed, and becomes unable to operate when the door is opened, because at that time, power source is interrupted by a door switch 3. The photo coupler 4 inputs pulse signals into a door open-and- close detecting and controlling part 5 and a fan motor controlling part 7. If this input is stopped, a control signal from the fan motor controlling part 7 is also stopped, and a fan motor 8 also stops. If no signals are inputted during a prescribed time period, it is determined that the door is kept open, and the door open-and-close detecting and controlling part 5 sends a signal to a buzzer 6, which informs that the door is open. Thus, the number of parts such as the photo coupler 4 can be decreased, and thereby reduction of size can be realized.
