Title: Estimating method of cause of degradation of oil
Inventor: HAYAMIZU EIJI
IPC: G01N30/88
Filed: 1991-08-08
Abstract: PURPOSE:To apply prescribed references and techniques to execution of an estimating method of a cause of degradation of oil wherein the cause of degradation of a specimen oil is estimated from a plurality of causes of degradation on the basis of the distribution of composition of a gas component contained in the specimen oil. CONSTITUTION:The degree of assurance of the genuineness of some cause of degradation is set beforehand as a function for the composition ratio of each gas component, in regard to each of a plurality of causes of degradation. The composition ratio of the gas component of the specimen oil is multiplied by the degree of assurance corresponding thereto in regard to each of the causes of degradation in a plurality, and the degree of assurance of that cause of degradation is judged to be higher as the product of the multiplication is larger.

Title: Control apparatus for supply power
Inventor: TAKITA HIROKI
IPC: H05B41/28
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To obtain a control apparatus by which power can be supplied to a load with good efficiency by a method wherein a microcomputer detects whether the energy of a magnetic field generated in a coil is zero or whether a current flowing in the coil is zero, and a switching element is operated. SOLUTION: A microcomputer 10 judges whether a zero-crossing state is detected by a zero-crossing detection circuit 9. It generates one-shot pulses having a designated width when the zero-crossing state is detected. A switching element 3 is operated so as to be set to an ON state. Then, a rectified current is made to flow to a coil 4, the switching element 3 and a ground E from a DC power-supply circuit 2. A magnetic field is generated in the coil 4. Whether the one-shot pulses are being generated or not is judged. When they are being generated, this operation is repeated, and a voltage at the charging voltage or higher of a charge and discharge capacitor 5 is generated. The generated voltage is passed through a reverse-blocking diode 6, and the charge and discharge capacitor 5 is charged.

Title: Semiconductor device
Inventor: OTSUKI YASUMASA
IPC: H01L23/02
Filed: 1985-09-09
Abstract: PURPOSE:To protect a device from warpage by a method wherein linear protrusions are provided on the primary surface or both surfaces of the device. CONSTITUTION:Beam-shaped protrusions are built of resin on the primary surface or both surfaces of a semiconductor device to be sealed in resin. A protuberance at the central portion of the primary surface serves as a marking and, at the same time, equips the portion for a semiconductor chip with a greater thickness. In a device designed as such, tension works on both sides of the chip during the process of hardening and shrinking of the molding material, decreasing the warpage the semiconductor device itself may be subjected to because of the difference in quantity of resin on both sides of the chip. This adds to mechanical strength and stabilized the mechanical characteristics of the semiconductor device.
