Title: Weight sensor
Inventor: SHOJI MASATO
IPC: G01G23/37
Filed: 1995-05-09
Abstract: PURPOSE: To enhance the accuracy and response of a weight sensor. CONSTITUTION: When no weight is applied, a CPU 7 delivers an offset regulation signal 5 corresponding to the offset output drift of a weight sensor. A D/A converter 9 converts the offset regulation signal 5 into an analog signal which is inputted, through reset function, to a DC differential amplifier 4 in order to correct the drift. When a weight is applied, the CPU 7 releases the reset function and offsets the output from a detection circuit 3 immediately before releasing the reset function and outputs the weight of an object 10 in the form of a weight output signal 8. Since the offset output drift it canceled constantly by performing the reset operation automatically, a highly accurate measurement is realized and high response is also realized because the waiting time accompanying conventional manual reset is not required.

Title: Epoxy resin composition
Inventor: KOYAMA TOORU
IPC: C08G59/68
Filed: 1984-06-01
Abstract: PURPOSE:The titled composition good in both storage stability and curability, prepared by mixing an epoxy resin composition with an alkali (alkaline earth) metal and an organic monocarboxylic acid. CONSTITUTION:An epoxy resin composition prepared by mixing an epoxy resin composition with (A) an alkali metal or∧an alkaline earth metal [e.g., NaOH, KOH, Ba(OH)2, or sodium methylate] and (B) an organic monocarboxylic acid (e.g., acetic or propionic acid). When an epoxy resin composition contains a curing catalyst, its gelation occurs within few days at room temperature and within tens of hr at 60 deg.C. When the gelatim time is prolonged by reducing the amount of the curing catalyst added, the properties (for example, heat distortion temperature and mechanical properties) of a cured product become insufficient for lack of curability. By the use of a combination of components A and B, the obtained resin composition can show good curability and good storage stability.

Title: Dc-dc converter
Inventor: KUDO YASUNORI
IPC: H02M3/28
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To obtain a DC-DC converter which can quickly charge a battery by preventing overdischarge, regardless of the shape, performance, and type of the battery. SOLUTION: A DC-DC converter discriminates the type or the state of a power supply battery 1 by means of a discriminating means 6 and properly uses a first boosting means 2, which connects the battery 1 to its primary winding and generates a voltage which is obtained by boosting the power supply voltage in its secondary winding, by controlling a switching means 4 by means of a control means 7 and a second boosting means 3 having an impedance higher than that of the first boosting means 2 has in its primary winding in accordance with the discriminated type or the state of the battery 1.  Even when the battery 1 is one where it causes overdischarge when the battery is charged by using only the first boosting means 2, the converter uses the second boosting means 3 which suppresses current in an initial charging period in which the risk of causing overdischarge is high, and during charging, the boosting means 3 is switched to the first boosting means, based on the charged partial voltage of a capacitor 5 detected by means of a detecting means 8.

Abstract: PROBLEM TO BE SOLVED: To stabilize electric characteristic and increase the yield at low cost by reducing the wettability to Ag or Cu metal material in the surfaces other than the contact surface of a cylindrical contact, and then heating and bonding it to an electrode bar. SOLUTION: Before an oxygen free copper-made electrode bar 11 is bonded to the recessed part 12d of a cylindrical contact 12 formed of alloys of Ag or Cu with WC or W, the treatment for reducing the wettability to these metals in its non-contact surface 12a and circumferential surface 12b is performed. This treatment is preferably formed of the etching treatment with a nitric acid solution or the formation of a Cr metal film by plating. This treatment may be performed only to the non-contact surface 12a. Thereafter, the electrode bar 11 is heated and bonded to the recessed part 12d of the contact 12 by use of a brazing filler metal 13.  Even when the excess of the wax material 13 flows out from the recessed part 12d, since the excessive portion of the brazing filler metal 13, even when it flows out from the recessed part 12d, never reaches the contact surface 12c, the contact is electrically stabilized, and the removing work of the brazing filler metal 13 adhered to the contact surface 12c is dispensed with.
